Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing communication transmission, and a communication device.

Background

For the terminal, the BWP (Bandwidth partial, partial bandwidth) can effectively reduce the terminal energy consumption, and the terminal can dynamically switch the BWP.

In network energy saving, energy consumption is a main index of the operator OPEX (Operating Expense, operation cost). Operator data shows that the operating cost of energy consumption in mobile networks is-23% of the total operating cost, most of the energy consumption being derived from the radio access network, especially from the AAU (Active Antenna Unit ). Currently, in a 5G (5 th-Generation, fifth Generation mobile communication technology) network, the energy consumption is about 2 to 3 times that of a 4G (the 4th th Generation mobile communication technology, fourth Generation mobile communication technology) network, so that research on energy saving technology for the 5G network energy consumption is urgent.

Detailed Description

In the embodiment of the invention, the term "and/or" describes the association relation of the association objects, which means that three relations can exist, for example, a and/or B can be expressed as follows: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

The term "plurality" in the embodiments of the present application means two or more, and other adjectives are similar thereto.

The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

For the terminal, the BWP can effectively reduce the terminal energy consumption. When the radio frequency bandwidth of the terminal is adjusted, the power consumption of the corresponding RF, A/D converter, D/A converter and digital front end can be further reduced along with the reduction of the bandwidth, so that the power consumption of the terminal is effectively reduced. For a terminal, when DL (downlink) or UL (uplink) traffic varies with time, or different BWP parameters are changed to adapt to traffic demand, SCS (subcarrier spacing), CP (control Plane) configurations are different, or the utilization of radio resources is optimized according to traffic demand, and interference is reduced, so that dynamic BWP can be switched.

When the BWP changes, the transmission bandwidth of the corresponding channel/signal also changes correspondingly, and at this time, the UE (User Equipment) cannot know the change of the BWP in time, which is easy to cause abnormal transmission. The base station BWP is a BWP indicating a transmission configuration to the base station. When the base station BWP changes, the transmission bandwidth of the corresponding channel/signal changes accordingly. For example, taking a CSI-RS signal as an example, the frequency domain resource of the CSI-RS transmission changes with the change of the first BWP information; while CSI-RS may be used for channel state estimation, time-frequency tracking, mobility measurements, beam measurements, time-domain tracking, frequency-domain tracking, etc. Thus, when the transmission frequency domain resource of the CSI-RS changes, the base station does not send the CSI-RS any more at the possible position of the original CSI-RS; or in the frequency domain position where the CSI-RS was not transmitted, the base station may increase the frequency domain range of the CSI-RS transmission. At this time, since the UE cannot know the change of the transmission band of the CSI-RS, there are two cases when receiving: 1) The UE transmits the position of the CSI-RS at the moment N of the base station, and the position of the frequency domain of the CSI-RS is not transmitted at the moment N+k after the position is changed, so that the measurement of the relevant CSI-RS can be still carried out; 2) And the UE does not send the position of the CSI-RS at the moment of the base station N, changes the frequency domain position of the CSI-RS sent at the moment of the N+k, and does not measure the CSI-RS. Both the above cases may cause inaccuracy in channel state information acquisition, thereby causing UE link adjustment bias; inaccuracy of the beam measurement may result in failure of beam reselection, unacknowledged for mobility measurement, and erroneous mobility operations, such as reselection, handover, etc., of the wrong cell.

Based on this, it is considered that the base station further reduces power consumption of the base station by adopting BWP, and signal reception is incorrect due to a corresponding channel caused by BWP handover, thereby affecting terminal performance, for example, link adaptation error caused by CSI-RS estimation error, error of mobility management, error of beam selection, error of estimation of channel time-frequency tracking, and the like. However, the prior art lacks a BWP scheme for a base station and fails to have a problem of CSI (Channel State Information ) performance impact on a terminal due to BWP change of the base station.

In the prior art, BWP is a continuous frequency domain resource, including DL BWP and UL BWP, and in the present protocol, BWP of each UE supports configuration of multiple sets of CSI-RS, i.e., CSI-resource control.

First, the UE BWP includes bwp#0 and normal data transmission BWP, wherein bwp#0 is initial BWP. The role of the initial BWP includes for the idle state UE to receive system information and complete random access.

Second, each terminal can support at most 4 dedicated BWP for connection-state UE data transmission, handover, etc. Further, the dedicated BWP includes: the active BWP and the inactive BWP, and the simultaneous active BWP is only 1.

Again, when BWP needs to be switched, for example, as the amount of UE data changes between larger and smaller BWP, or as the UE traffic changes, the UE switches to BWP of a different subcarrier spacing, so that an activation/deactivation operation of BWP is required. For activation and/or deactivation of BWP, the following several ways may be included: DCI based, RRC based, timer based. In the method based on the DCI, the scheduling information in the DCI indicates the resource allocation in the current BWP, and the DCI indicates the target BWP ID, wherein the BWP ID adopts 2bit explicit indication.

Timer-based BWP switching is a protection mechanism for dynamic BWP switching reliability. The idea is as follows: defining an default BWP, and switching back to the default BWP when a specific condition is satisfied. Specifically, when the UE switches to non-default BWP, a timer is started; restarting a timer every time the UE receives scheduling DCI at an active BWP; if the timer times out, the UE switches back to default BWP.

That is, the current frequency domain BWP is only applied to the terminal side, and a BWP scheme for the base station is absent. Moreover, when the base station BWP changes, the transmission bandwidth of the corresponding channel/signal also changes accordingly. At this time, for the UE, since the change of the transmission band of the CSI-RS cannot be known, the channel state information is obtained inaccurately during the reception, thereby causing the link adjustment deviation of the UE; inaccuracy of the beam measurement may result in failure of beam reselection, unacknowledged for mobility measurement, and erroneous mobility operations, such as reselection, handover, etc., of the wrong cell. That is, in the prior art, the UE cannot know the change of the BWP in time, which is easy to cause abnormal transmission.

The embodiment of the invention provides a communication transmission processing method, a device and communication equipment. The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

As shown in fig. 1, a communication transmission processing method provided in an embodiment of the present invention is executed by a second communication device, and includes:

step 101, configuring first BWP information and/or second BWP information; wherein the first BWP information is network side BWP information, and the first BWP information and the second BWP information are associated.

It should be noted that, the first BWP information is network side BWP information, and may also be understood as BWP information configured for transmission by the second communication device (e.g., base station). Wherein the first BWP information and/or the second BWP information may be configured by the network (e.g., base station node, core network, terminal node, etc.). The following description will be given by taking the second communication device as a base station and the first communication device as a UE as an example.

And configuring the first BWP information and/or the second BWP information may be: based on RRC signaling, based on SIB (System information block, system message block) signaling, at least one of the dynamic signaling is performed.

Step 102, transmitting the first BWP information and/or the second BWP information.

It should be noted that, the first BWP information of the second communication device is a segment of resources on the frequency domain, where the resources may be located on different carriers, may be located on different cells (for example, a primary cell or a secondary cell), and may be located on different frequency bands (for example, an licensed frequency band, a shared frequency band, etc.). The second BWP information is also a section of resource in the frequency domain, and as such, the resource may be located in a different carrier; or may be located in different cells (e.g., a primary cell or a secondary cell), or may be located in different frequency bands (e.g., licensed bands, shared bands, etc.).

The first communication device may determine BWP information used by the first communication device according to the first BWP information and/or the second BWP information after receiving the first BWP information and/or the second BWP information.

In this way, when the BWP of the second communication device changes, by configuring the first BWP information and/or the second BWP information, at this time, the first BWP information and the second BWP information are associated and transmitted to the first communication device, so that the first communication device can perform a corresponding applicable operation based on the change of the BWP of the second communication device according to the first BWP information and/or the second BWP information, thereby avoiding the problem of abnormal transmission.

In this embodiment, by configuring the associated first BWP information and/or second BWP information and transmitting the first BWP information and/or second BWP information, the UE can timely learn the change of the BWP when the BWP changes, thereby realizing network energy saving.

It should be noted that, in this embodiment, the first BWP information is BWP information of the second communication device, and the second BWP information is BWP information of the first communication device. The first network side device may configure one or more first BWP information; one or more second BWP information may be configured.

Optionally, each of the first BWP information and the second BWP information may include at least one configuration of at least one of the following parameters:

BWP identification ID;

BWP resource indication;

a Physical Downlink Control Channel (PDCCH);

a physical downlink shared channel PDSCH;

sounding reference signals, SRS;

channel state information reference signal CSI-RS;

discontinuous reception, DRX;

a Physical Uplink Control Channel (PUCCH);

a Physical Uplink Shared Channel (PUSCH); or (b)

The radio resource control RRC.

As such, taking the CSI-RS parameter as an example, the first BWP information and the second BWP information may include at least one of the following: the resource set configuration of at least one CSI-RS, the resource configuration of a plurality of CSI-RSs contained in each resource, the configuration of a plurality of measurement parameters or the configuration of a plurality of reporting parameters.

Optionally, the association of the first BWP information and the second BWP information includes that the first BWP information and the second BWP information have a preset mapping relation.

It should be noted that, the mapping relationship between the first BWP information and the second BWP information may be an association relationship preconfigured by the network.

The preset mapping relation comprises at least one of the following:

In case one, a mapping between the first BWP information and at least one of the second BWP information.

That is, the preset mapping relationship may be a one-to-one mapping relationship, and may be a one-to-many mapping relationship.

For example, N first BWP information and M second BWP information are configured, wherein the mth second BWP information may be associated for the nth first BWP information; the nth first BWP may be associated with m second BWP information.

Specifically, if the first BWP information is associated with one second BWP information, the BWP information used by the first communication device may be switched to the second BWP information associated with the first BWP information;

if the first BWP information is associated with a plurality of second BWP information, BWP information used by the first communication device may be switched to at least one of the plurality of second BWP information associated with the first BWP information.

It should be noted that, according to the at least one second BWP information and the preset rule, the first communication device may switch the BWP information used by the first communication device to at least one of the plurality of second BWP information, which may specifically be: the BWP information used by the first communication device is switched to the second BWP information determined according to the preset rule.

priority of the second BWP information;

the number may be an identification number of the second BWP information or a sequence number of the second BWP information; or (b)

The size of the data packet to be transmitted.

As an optional embodiment of the present invention, the preset rule includes at least one of the following:

and (one) determining at least one of the plurality of second BWP information satisfying the priority of the first preset condition as BWP information used by the first communication device according to the predefined priorities of the plurality of second BWP information. The priority meeting the first preset condition may include at least one of the following:

The second BWP information with the highest priority;

second BWP information with the lowest priority;

the second BWP information having the first priority.

And (II) determining at least one of the plurality of second BWP information satisfying the number of the second preset condition as the BWP information used by the first communication device according to the number predefined by the plurality of second BWP information. Wherein, satisfying the second preset condition number may include at least one of:

the second BWP information with the largest number;

the second BWP information with the smallest number;

and the second BWP information numbered as the first number.

For example, when the configuration of the first BWP information is changed, the change of the configuration of the second BWP information may be implicitly indicated according to the mapping relationship between the first BWP information and the second BWP information, i.e., the configuration of the second BWP information associated with the first BWP information is changed according to the implicit indicated relationship. For example, when the first BWP information is configured as bwp_1, the corresponding second BWP information is configured as bwp_3; when the configuration of the first BWP information is changed to bwp_2, the configuration of the corresponding second BWP information is also changed to bwp_4.

And thirdly, determining BWP information used by the first communication device according to the size of the data packet to be transmitted estimated by the base station. For example, a handover to an appropriate BWP is indicated by the DRS (Demodulation Reference Signal ), that is, the first BWP information and/or the second BWP information is carried in the DRS.

Alternatively, in the above manner, the BWP information used by the first communication device may be determined based on the predefined default second BWP information, that is, at least one of the predefined default second BWP information.

In case two, a mapping between the first BWP information and at least one configuration of at least one parameter in the second BWP information.

That is, the first BWP information includes at least one configuration of at least one parameter of the second BWP information.

In particular, the base station indicates the first BWP information, and the at least one configuration of the at least one parameter of the second BWP information is changed according to the mapping between the at least one configuration of the at least one parameter of the first BWP information and the second BWP information; the at least one configuration of the at least one parameter of the second BWP information may be switched to the at least one configuration of the at least one parameter of the second BWP information associated with the first BWP information.

For example, a configuration of a parameter of the second BWP information associated with the first BWP information is changed by implicitly indicating that a configuration of a parameter of the associated second BWP information is also changed when the first BWP information is changed. Taking CSI-RS as an example, when the first BWP information is configured as bwp_1, the resource configuration of CSI-RS of the corresponding second BWP information is configured as CSI-RS-config1, and when the first BWP information configuration is changed to bwp_2, the resource configuration of CSI-RS of the corresponding second BWP information is also changed to CSI-RS-config2.

In case three, a mapping between at least one configuration of at least one parameter in the first BWP information and the second BWP information.

That is, the second BWP information includes at least one configuration of at least one parameter of the first BWP information.

Specifically, the base station indicates the second BWP information, and obtains at least one configuration of at least one parameter of the first BWP information according to a mapping between the second BWP information and the at least one configuration of at least one parameter of the first BWP information.

For example, when the second BWP information is changed, a configuration of a parameter of the associated first BWP information is changed. Taking CSI-RS as an example, when the second BWP information is configured as bwp_3, the resource configuration of CSI-RS of the corresponding first BWP information is configured as CSI-RS-config3, and when the second BWP information configuration is changed to bwp_4, the resource configuration of CSI-RS of the corresponding first BWP information is also changed to CSI-RS-config4.

In addition, it is known from the above that the first BWP information and the second BWP information may each include at least one configuration of at least one parameter, and then a mapping between the at least one configuration of the at least one parameter in the first BWP information and the at least one configuration of the at least one parameter in the second BWP information satisfies a mapping between the at least one configuration of the at least one parameter in the first BWP information and the second BWP information or a mapping between the at least one configuration of the at least one parameter in the first BWP information and the second BWP information.

In case four, at least one of the first BWP information and the second BWP information is mapped.

For example, configuring N first BWP information, M second BWP information, wherein the nth first BWP information is associated with the mth second BWP information; it is also possible that the N first BWP associates the mth second BWP information.

Optionally, the parameter includes at least one of:

BWP identification ID;

BWP resource indication;

a Physical Downlink Control Channel (PDCCH);

a physical downlink shared channel PDSCH;

sounding reference signals, SRS;

channel state information reference signal CSI-RS;

discontinuous reception, DRX;

a Physical Uplink Control Channel (PUCCH);

a Physical Uplink Shared Channel (PUSCH); or (b)

The radio resource control RRC.

Specifically, as an optional embodiment of the present invention, at least one configuration of at least one parameter of each first BWP information associated with the second BWP information is configured. Taking CSI-RS as an example, the following can be used:

(1) The nth first BWP information (identified by the number n) may be associated with the mth 1 CSI-RS resource set configuration, the mth 2 CSI-RS resource configuration, the mth 3 CSI-RS measurement parameter configuration, and the mth 4 CSI-RS reporting parameter configuration of the second BWP information;

(2) The nth first BWP information (identified by the number n) may also be associated with b1 CSI-RS resource set configuration, b2 CSI-RS resource configuration, b3 CSI-RS measurement parameter configuration, and b4 CSI-RS reporting parameter configuration of the second BWP information. Optionally, in this embodiment, the second BWP information is a subset of the first BWP information. For example, the first BWP information is a complete set of second BWP information of the at least one UE, and if the first BWP information includes N BWP configurations, N is a positive integer greater than or equal to 1, the second BWP information includes M BWP configurations, M is a positive integer greater than or equal to 1, and may specifically include at least one of the following:

(1) The nth BWP configuration in the first BWP information includes M BWP configurations of the at least one UE. For example, the first BWP information includes N BWP configurations, and an nth (e.g., 1 st, 2 nd, 3 rd, … th, etc.) BWP configuration includes M BWP configurations of the at least one UE.

(2) The N BWP configurations in the first BWP information include M BWP configurations of the at least one UE. For example, the first BWP information includes N BWP configurations including M BWP configurations of at least one UE.

The first BWP information includes N BWP configurations and the second BWP information includes M BWP configurations. The second BWP information comprises at least one configuration of at least one parameter, wherein the parameter comprises at least one configuration. Taking CSI-RS parameters as an example, each of the second BWP information may include at least one of: the method comprises the steps of configuring a resource set of at least one CSI-RS, configuring resources of a plurality of CSI-RSs contained in each resource, configuring a plurality of measurement parameters and configuring a plurality of reporting parameters.

Optionally, in case of transmitting the first BWP information, the second BWP information is determined by the first BWP information and a first mapping relation; in case of transmitting the second BWP information, the first BWP information is determined by the second BWP information and a second mapping relation; in case of transmitting the first BWP information and the second BWP information, the first BWP information and the second BWP information satisfy a third mapping relation;

In case one, the second BWP information implicitly associates the first BWP information, i.e., the second BWP information implicitly associates the first BWP information through the first mapping relation:

for example, a preconfigured multiple sets of CSI-RS transmission resource sets are determined, and the base station side configures second BWP information through RRC signaling, including multiple groups resource sets, for example: CSI-RS for CSI report (report), CSI-RS for mobility, CSI-RS for tracking, wherein each set of resources is implicitly associated with the first BWP information. The specific process comprises the following steps:

(1) The base station side configures a resource group for the terminal through high-layer signaling;

(2) The UE receives switching indication information of first BWP information sent by a base station;

(3) The UE determines a resource group associated with the first BWP information and receives the CSI-RS according to the configuration.

In case two, the second BWP information explicitly associates the first BWP information, i.e., the first BWP information displays the associated first BWP information through the third mapping relation.

Here, DCI, or a power saving signal, may be employed, with the association indicating the first BWP information and the second BWP information. That is, one DCI or one power saving signal may be used to simultaneously indicate the first BWP information and the second BWP information. The specific process comprises the following steps:

(1) Configuring first BWP information and second BWP information;

(2) And transmitting switching information of the first BWP information (i.e., switching indication information) and/or switching information of the second BWP information, which is carried on the DCI, and may indicate both the first BWP information and the second BWP information.

(3) The UE receives switching indication information of first BWP information sent by a base station;

(4) The base station transmits information (for example, CSI-RS) according to the configured first BWP information;

(5) The UE receives the CSI-RS according to the received switching indication information of the second BWP information.

In case three, the first BWP information implicitly associates the second BWP information, i.e., the first BWP information implicitly associates the second BWP information through the second mapping relation:

for example, the UE receives handover indication information of the second BWP information transmitted by the base station, and the UE can determine first BWP information associated with the second BWP information.

Optionally, the validation time of the first BWP information and the validation time of the second BWP information are the same; or, there is a time interval between the effective time of the first BWP information and the effective time of the second BWP information; wherein the validation time represents a time when the corresponding BWP information is used.

For example, at time N, the base station uses the first BWP information, i.e., the first BWP information effective time is time N; at time n+k, the UE uses the second BWP information, k being a time interval, i.e., the second BWP information validation time is time n+k. Alternatively, at time N, the base station uses the first BWP information, the UE uses the second BWP information, and the effective time of the first BWP information and the second BWP information is time N. The specific process may include the steps of:

(1) Configuring first BWP information and second BWP information;

(2) The base station transmits DCI at the moment N, wherein the DCI carries switching information of first BWP information;

(3) At time n+k, the base station transmits information on the configured first BWP information, the information including CSI-RS information;

at time n+k, the UE side acquires update information of the second BWP information and receives CSI-RS information.

It should be noted that, the first communication device may determine, according to the first BWP information and/or the second BWP information, BWP information used by the first communication device, including at least one of the following:

(1) And determining at least one second BWP information according to the received first BWP information and the first mapping relation, and determining BWP information used by the first communication device according to the at least one second BWP information.

Specifically, at least one of the following may be notified via the target carrier:

It should be noted that, the second communication device may also transmit the first BWP information and/or the second BWP information through a MAC (Media Access Control ) -CE (Control Element), and the transmission process may be triggered based on a timer.

Here, the sequence may be a signal. The signals may be sent periodically, aperiodically, or on demand. For example, the signal may include at least one of: wake-up signal, synchronization signal, channel state indication reference signal, time-frequency tracking reference signal, discovery signal.

It should be noted that, the wake-up signal is used for carrying wake-up information; the synchronous signal is used for performing coarse synchronization or fine synchronization; the channel state indication reference signal is used for indicating the channel state; the time-frequency tracking reference signal is used for performing time-frequency tracking; the discovery signal is used for node discovery, including node identification, channel quality to the measuring node. Here, channel quality includes large scale channel quality, possibly small scale channel quality.

As an optional embodiment of the present invention, the carrying manner of the first BWP information and/or the second BWP information includes at least one of the following:

(1) The first BWP information is carried on the first signal, wherein the first signal may comprise at least one of: cell-specific signal, UE-group signal, UE-specific signal;

(3) The first BWP information and the second BWP information are carried on a third signal, wherein the third signal may include at least one of: cell-specific signal, UE-group signal, UE-specific signal.

If the first BWP information and the second BWP information are transmitted, the first signal and the second signal may be transmitted simultaneously or may be transmitted according to a certain time difference, in addition to being carried on the third signal. The first BWP information is carried on the first signal, e.g. at a first instant in time, and the second BWP information is carried on the second signal, e.g. at or after the first instant in time.

Here, the first signal, the second signal, and the third signal may be multiplexed or orthogonal.

As another optional embodiment of the present invention, when the target carrier is a signal, the first BWP information and/or the second BWP information is transmitted through the target carrier, including at least one of the following:

(1) Transmitting first BWP information through a first signal;

(2) Transmitting the second BWP information and/or at least one configuration of at least one parameter of the second BWP information through the second signal;

(3) And transmitting the first BWP information and the second BWP information and/or at least one configuration of at least one parameter of the second BWP information through the third signal.

Wherein the first BWP information is transmitted via the first signal at a first instant in time and the second BWP information and/or the at least one configuration of the at least one parameter of the second BWP information is transmitted via the second signal at or after the first instant in time.

Wherein the signal multiplexing condition includes at least one of:

Here, DCI (Downlink Control Information ) carrying the first BWP information and/or the second BWP information handover may be carried in the first common search space, for example, in CORESET #0, and/or other CORESETs.

It should be noted that the first common search space may be multiplexed with other resources (common search space resources) or orthogonal to the resources. For example, the first dynamic signaling carrying the first BWP information may be carried in a first common search space, which is multiplexed or orthogonal with other common search space resources.

Wherein the first common search space comprises at least one of the following search spaces: type0, 0A, 1A, 2A, type3.

It should be further noted that, the DCI carrying the first BWP information and/or the second BWP information, that is, the switching DCI of the first BWP information (i.e., the switching indication information) and/or the switching DCI of the second BWP information, may also be carried in the first UE-specific search space.

Wherein the first UE-specific search space includes at least one of:

DL scheduling DCI;

UL scheduling DCI;

the first BWP information and/or the second BWP information.

As an optional embodiment of the present invention, when the target carrier is dynamic signaling, the first BWP information and/or the second BWP information is transmitted through the target carrier, including at least one of the following:

(1) The first BWP information is carried on the first dynamic signaling, wherein the first dynamic signaling may include at least one of: cell-specific DCI, UE-group DCI, and UE-specific DCI;

(2) The second BWP information is carried on second dynamic signaling, wherein the second dynamic signaling may include: UE-specific DCI and/or UE-group DCI;

(3) The first BWP information and the second BWP information are carried on third dynamic signaling, wherein the third dynamic signaling may comprise at least one of: at least one of Cell-specific DCI, UE-group DCI and UE-specific DCI.

Wherein, if the first BWP information and the second BWP information are transmitted, the first BWP information is carried on the first dynamic signaling at the first time, and the second BWP information is carried on the second dynamic signaling at the first time or after the first time.

For example, as shown in fig. 7, the first BWP information is switched, and/or the second BWP information is changed, and/or at least one configuration of at least one parameter of the second BWP information may indicate the first BWP information and the second BWP information simultaneously through one DCI (DCI for indicating the base station side BWP switch and the terminal side BWP switch), and then the first BWP information and the second BWP information are changed simultaneously at this time.

As another example, as shown in fig. 8, the base station changes the first BWP information after a first time window after transmitting DCI (DCI for indicating a base station side BWP handover and a terminal side BWP handover); the UE changes the second BWP information after a second time window after correctly receiving the DCI.

It should be noted that, the base station may use the first dynamic signaling (e.g., cell-specific DCI or ue-group DCI) to carry the handover signaling of the first BWP information, after the first BWP information is handed over, if the underlying second BWP information is handed over to the default second BWP information, and further no additional signaling is needed for the handover indication of the second BWP information; or if the current second BWP information and the first BWP information after the base station side handover have an intersection, the second BWP information may not be handed over; otherwise, the second BWP information is switched through the second dynamic signaling.

As an alternative embodiment of the present invention, as shown in fig. 6, when the first BWP information is switched, the base station transmits the second BWP information (DCI for indicating the terminal side BWP switching) by switching DCI1 of the first BWP information (DCI for indicating the base station side BWP switching) after transmitting the DCI, for indicating the second BWP information.

Specifically, if the first BWP information is transmitted through the first dynamic signaling, the first BWP information implicitly correlates with the second BWP information;

the first BWP information may be transmitted through the first dynamic signaling at the first time, and after the first time, the UE side acquires the information of the BWP updated at the UE side, that is, the UE acquires the second BWP information according to the association relationship between the first BWP information and the second BWP information.

As shown in fig. 2, when the first BWP information is changed, the base station informs the first BWP information (i.e., the first BWP information used by the second communication device) of the UE handover through DCI1 (DCI for indicating the base station side BWP handover); the UE simultaneously determines BWP information, i.e., second BWP information, used by the first communication device based on the first mapping relation.

As shown in fig. 3, when the first BWP information is changed, the base station informs the UE of the first BWP information for handover through DCI1 (DCI for indicating the base station side BWP handover); the UE acquires second BWP information (i.e., determines BWP information used by the first communication device) at some point after receiving the first BWP information, based on the first mapping relation, after receiving the indication information indicating the change of the first BWP information and acquiring the indication information content (e.g., the first BWP information).

As shown in fig. 4, when the first BWP information is changed, the base station informs the UE of the second BWP information of the handover through DCI2 (DCI for indicating the terminal-side BWP handover); the UE uses the second BWP information at the same time after receiving the indication information indicating the change of the second BWP information and acquiring the indication information content.

As shown in fig. 5, when the first BWP information is changed, the base station informs the UE of the second BWP information of the handover through DCI2 (DCI for indicating the terminal-side BWP handover); after receiving the indication information indicating the change of the second BWP information and acquiring the indication information content, the UE may use the second BWP information at a time when there is a need, such as when data/signal transmission is required. The UE does not need to perform data/signal transmission and may not perform update of the second BWP information.

Here, taking signaling as an example of the target carrier, the following is specifically described:

optionally, in the case that the target carrier is signaling, specifically including at least one of the following cases:

Optionally, in some embodiments, the second bit field includes at least one sub-field, each sub-field including at least one terminal packet information;

the terminal packet information includes the second BWP information.

Wherein each terminal group may include one or more terminals.

Specifically, the following description is given with reference to the accompanying drawings:

in case one, the signaling includes a first bit field for carrying the first BWP information and a second bit field for carrying at least one of the second BWP information.

Example 1: as shown in fig. 9, a signaling format diagram of a cell-specific signaling carrying first BWP information and second BWP information is shown. The first common search space carries first BWP information and second BWP information.

In this example, the first BWP information and the second BWP information may be carried in cell-specific signaling (i.e., a target bearer) as handover indication information, and thus, the cell-specific signaling is used to indicate handover of the first BWP information and handover of the second BWP information.

At this time, the second bit field in the cell-specific signaling includes two sub-fields, the first sub-field carries the second BWP information of UE1, and the second sub-field carries the second BWP information of UE 2. Here, one UE is one terminal group (UE-group).

Example 2: as shown in fig. 10, one of signaling format diagrams (i.e., diagrams of handover indication information) when the first BWP information and the second BWP information are carried in the UE-group DCI is shown. The first common search space carries first BWP information and second BWP information.

In this example, the first BWP information and the second BWP information are carried as handover indication information in dynamic signaling of the UE-group (e.g., UE-group DCI), which includes the first BWP information and/or the second BWP information. Wherein the second BWP information is second BWP information corresponding to one UE-group.

At this time, the second bit field in the cell-specific signaling includes N sub-fields, and each sub-field carries the second BWP information of the corresponding terminal group. Here, a plurality of UEs is one terminal group. Each sub-field may also carry first information, such as wake-up information.

Example 3: as shown in fig. 13, a signaling format diagram of the first BWP information and the second BWP information carried in the UE-specific DCI is shown. The first UE-specific search space carries first BWP information and second BWP information.

In this example, the handover indication information is carried in dynamic signaling of the UE-specific, which is used to carry the handover information of the second BWP information and the first BWP information.

In case two, the signaling includes at least one third bit field, where the third bit field is used to carry the first BWP information and the second BWP information;

example 4: as shown in fig. 11, the second signaling format diagram is shown when the first BWP information and the second BWP information are carried in the UE-group DCI. The first common search space carries first BWP information and second BWP information.

In this example, the handover indication information is carried in dynamic signaling of the UE-group, and one third bit field of the dynamic signaling corresponds to one terminal group, where the third bit field carries the first BWP information and the second BWP information of the corresponding terminal group.

In case three, the signaling comprises at least one fourth bit field for carrying the first BWP information or the second BWP information.

Example 5: as shown in fig. 12, the third signaling format diagram when the first BWP information and the second BWP information are carried in the UE-group DCI is shown. The first common search space carries first BWP information and second BWP information.

In this example, the first BWP information and the second BWP information are carried as handover indication information in dynamic signaling of the UE-group, and one fourth bit field of the dynamic signaling corresponds to one terminal group, and the fourth bit field is used to carry the second BWP information or the first BWP information of the corresponding terminal group. Wherein the second BWP information is second BWP information corresponding to one UE-group.

Optionally, in the case that the target vector is a sequence, specifically at least one of the following cases is included:

the terminal packet information includes the second BWP information.

Wherein each terminal group may include one or more terminals.

In a first case, the sequence includes a first-level sequence for carrying the first BWP information and a second-level sequence for carrying at least one of the second BWP information.

As yet another alternative embodiment of the present invention, when the target carrier is a signal, specific examples are as follows:

example 1: as shown in fig. 14, a signal format of a cell-specific signal carrying the first BWP information and the second BWP information is shown. The first cell-level signal carries first BWP information and/or second BWP information. In this example, the handover indication information may be carried in a cell-specific signal (i.e. a target bearer, in particular, a first cell-level signal), so that the cell-specific signal is used to indicate the handover of the first BWP information and/or the handover of the second BWP information.

At this time, the second level sequence carrying the second BWP information in the cell-specific signal includes 2 sub-level sequences, where one sub-level sequence carries the second BWP information of UE1 and the other sub-level sequence carries the second BWP information of UE 2. Here, one UE is one terminal group (UE-group).

Note that the handover indication information may be carried in the same signal, for example, the third signal. Wherein the first BWP information and the second BWP information may be carried on different resources of the same signal, the resources including at least one of: time domain, space domain, code domain, frequency domain; the first BWP information and the second BWP information may also be carried on different signals; the first BWP information and the second BWP information may also be carried on different levels (e.g., different cell levels) of the same signal.

Example 2: as shown in fig. 15, a signal format diagram of the case where the handover indication information is carried in the UE-group level signal is shown. The first UE-group level signal carries first BWP information and second BWP information. In this example, the handover indication information is carried in a UE-group level signal (i.e. a target bearer, in particular a first UE-group level signal), which may include: the first BWP information and/or the second BWP information; wherein the second BWP information is second BWP information corresponding to one UE-group.

At this time, the second-level sequence carrying the second BWP information in the UE-group level signal includes 3 sub-level sequences, each sub-level sequence carries the second BWP information of the corresponding terminal group, the sub-level sequence of UE-group1 carries the second BWP information of UE-group1, the sub-level sequence of UE-group2 carries the second BWP information of UE-group2, and the sub-level sequence of UE-group3 carries the second BWP information of UE-group 3. Here, a plurality of UEs is one terminal group. Wake-up information may also be carried in each sub-level sequence.

Example 3: as shown in fig. 18, a signal format diagram of the first BWP information and the second BWP information when they are carried in the first UE-specific signal is shown. The first UE-specific signal carries first BWP information and second BWP information.

In this example, the handover indication information is carried in a first UE-specific signal that is used to indicate the handover of the second BWP information and the handover of the first BWP information.

At this time, the second-level sequence in the first UE-specific signal carries second BWP information.

It should be noted that, here, the first BWP information and the second BWP information may be carried on different time-frequency resources.

In case two, the sequence includes at least one third-level sequence for carrying the first BWP information and the second BWP information.

Example 4: as shown in fig. 16, a signal format diagram (i.e., a diagram of handover indication information) when the first BWP information and the second BWP information are carried in the UE-group level signal is shown. The first common search space carries first BWP information and second BWP information.

In this example, the handover indication information is carried in a UE-group level signal, and the third level sequence is used to carry the handover information of the first BWP information and the second BWP information. Here, the BWP information of the UE-group includes second BWP information of at least one UE-group.

At this time, the UE-group level signal includes 3 third-level sequences, each of which carries the first BWP information and the second BWP information, and the third-level sequences may also carry the first information, such as wake-up information.

In case three, the sequence includes at least one fourth-level sequence for carrying the first BWP information or the second BWP information.

Example 5: as shown in fig. 17, is an intention of a signal format when the first BWP information and the second BWP information are carried in the UE-group level signal. The first UE-group level signal carries first BWP information and second BWP information.

In this example, the handover indication information is carried in a signal of the UE-group, and the fourth order sequence is used to carry handover information of the second BWP information. Here, the second BWP information is second BWP information corresponding to one UE-group.

At this time, the UE-group level signal includes 3 fourth-level sequences, each of which carries the first BWP information or the second BWP information, and the third-level sequences may also carry the first information, such as wake-up information.

In this way, when the BWP (i.e., the first BWP information) of the base station changes, the base station BWP parameters (the first BWP information) are associated through the UE configuration parameters (the second BWP information), so that after the BWP of the base station is switched, the UE can receive the configuration parameters (e.g., CSI-RS) corresponding to the new BWP of the base station according to the indication of the base station, so that the UE can perform normal operations (e.g., CSI-Report, channel estimation or channel tracking operation, etc.) based on the signal, thereby solving the problems of UE link adaptation error, inaccurate channel estimation and time/frequency accurate synchronization, etc. caused by the frequency domain resource adjustment of the CSI-RS due to the BWP change of the base station.

Optionally, the first communication device may further determine BWP information used by the second communication device according to the first BWP information and/or the second BWP information.

Optionally, this embodiment may specifically include the following implementation manner:

according to the received second BWP information and the second mapping relation, taking first BWP information having the second mapping relation with the second BWP information as BWP information used by the second communication device; or, the received first BWP information is used as BWP information for the second communication device.

According to the communication transmission processing method provided by the embodiment of the invention, the associated (implicit or explicit) first BWP information and/or second BWP information are configured, and the first BWP information and/or the second BWP information are transmitted, so that when the change of the base station BWP occurs, the UE can timely know the change of the base station BWP, the problem of abnormal transmission is avoided, and the network energy saving of the frequency domain BWP is realized.

As shown in fig. 19, a communication transmission processing method provided in an embodiment of the present invention is executed by a first communication device, and includes:

step 1901, receiving first BWP information and/or second BWP information; wherein the first BWP information is network side BWP information, and the first BWP information and the second BWP information are associated;

Step 1902, determining BWP information used by the first communication device according to the first BWP information and/or the second BWP information.

The following description will be given by taking the second communication device as a base station and the first communication device as a UE as an example. The UE may transmit according to the received first BWP information and/or second BWP information, and may perform corresponding operations on the corresponding resources, for example: channel state measurement based on CSI, channel state report, mobility measurement based on CSI-RS, channel time-frequency tracking based on CSI-RS, beam measurement and management based on CSI-RS.

Wherein the second BWP information includes information of BWP of the at least one UE or information of BWP of the at least one UE packet.

In this way, when the BWP of the second communication device changes, the first communication device may determine the BWP information used by the first communication device through the configured first BWP information and/or second BWP information, so that a corresponding applicable operation can be performed based on the change in BWP of the second communication device, thereby avoiding the problem of transmission abnormality.

It should be noted that, the second BWP information of the first communication device is a segment of resources on the frequency domain, and the resources may be located on different carriers, may be located on different cells (for example, a primary cell or a secondary cell), and may be located on different frequency bands (for example, an licensed frequency band, a shared frequency band, etc.).

the preset mapping relation comprises at least one of the following:

Optionally, the parameter includes at least one of:

BWP identification ID;

BWP resource indication;

a Physical Downlink Control Channel (PDCCH);

a physical downlink shared channel PDSCH;

sounding reference signals, SRS;

channel state information reference signal CSI-RS;

discontinuous reception, DRX;

a Physical Uplink Control Channel (PUCCH);

a Physical Uplink Shared Channel (PUSCH); or (b)

The radio resource control RRC.

That is, the second BWP information includes at least one of the following parameters: BWP id, BWP resource indication, configuration of PDCCH on BWP, configuration of PDSCH on BWP, configuration of CSI-RS, parameter configuration of DRX, configuration of PUCCH, configuration of PUSCH, configuration of SRS, configuration of RRC parameters.

It should be noted that, the second BWP information may display or implicitly associate the first BWP information, which is specifically described as follows:

the first BWP information is implicitly associated with the second BWP information, i.e., the second BWP information is implicitly associated with the first BWP information through the first mapping relation.

The base station side configures the second BWP information through RRC signaling, including a plurality of group resource sets, for example: CSI-RS for CSI report (report), CSI-RS for mobility, CSI-RS for tracking, wherein each set of resources is associated with first BWP information.

The second BWP information explicitly associates the first BWP information, i.e., the first BWP information displays the associated first BWP information through the third mapping relation.

Specifically, DCI, or a power saving signal, may be used to associate the first BWP information and the second BWP information. That is, one DCI or one power saving signal may be used to simultaneously indicate the first BWP information and the second BWP information.

(III) the first BWP information implicitly associates the second BWP information, i.e., the first BWP information implicitly associates the second BWP information through a second mapping relation:

For example, at time N, the base station uses the first BWP information, i.e., the first BWP information effective time is time N; at time n+k, the UE uses the second BWP information, k being a time interval, i.e., the second BWP information validation time is time n+k. Alternatively, at time N, the base station uses the first BWP information, the UE uses the second BWP information, and the effective time of the first BWP information and the second BWP information is time N. The specific process comprises the following steps:

(1) Configuring first BWP information and second BWP information;

For example, at time N, the DCI indicates the first BWP information update, or at time n+k, the first BWP information and the second BWP information update.

It should be noted that, considering that additional receiving processing time is required after the UE receives the DCI, the base station estimates or confirms that the UE side performs the update of the first BWP information after receiving the update indication information, so that the UE side also performs the update of the corresponding second BWP information.

For another example, at time N, the DCI indicates the first BWP information update, and at time n+x, the second BWP information update. The method is suitable for the situation that when the UE side needs to perform signal or data transmission, the second BWP information update is required. For example, for periodic CSI-RS, the UE may update the second BWP information before the reception moment arrives.

Optionally, the targeting vector comprises at least one of:

The signaling, for example, may be RRC signaling, or SIB signaling; or (b)

A sequence;

wherein the signaling includes at least one of:

static signaling;

semi-static signaling; or (b)

Dynamic signaling.

It should be noted that the bandwidths of the first BWP information and the second BWP information may be irrelevant.

As an alternative embodiment of the present invention, the switch indication of the first BWP information and the switch indication of the second BWP information are independent, i.e. can be transmitted using two different DCIs.

Here, the switch indication of the first BWP information and the switch indication of the second BWP information may be transmitted simultaneously, specifically as follows:

step 1: the base station sends CELL-specific DCI (or UE-group DCI) for bearing the switching instruction of the first BWP information;

step 2: the base station transmits UE-specific DCI for carrying a handover indication of the second BWP information: when the base station has a handover (and regardless of whether the UE is scheduled) the handover indication of the second BWP information is carried in its scheduling DCI.

Alternatively, the following specific steps may be employed:

step 1: the base station sends CELL-specific DCI to bear the switching instruction of the first BWP information;

step 2: the base station transmits UE-group DCI (or UE-specific DCI) for carrying a handover indication of the second BWP information: when the base station has a handover (and regardless of whether the UE is scheduled) the handover indication of the second BWP information is carried in its scheduling DCI.

As a further alternative embodiment of the present invention, the switch indication of the first BWP information and the switch indication of the second BWP information are carried in one DCI. For example, the switch indication of the first BWP information and the switch indication of the second BWP information are both carried in a third dynamic signaling (e.g., UE-Specific DCI or UE-group DCI).

Optionally, the determining, according to the first BWP information and/or the second BWP information, BWP information used by the first communication device includes at least one of the following:

and (one) determining at least one second BWP information according to the received first BWP information and the first mapping relation, and determining BWP information used by the first communication device according to the at least one second BWP information.

As an optional embodiment of the present invention, the at least one second BWP information is second BWP information having the first mapping relation with the first BWP information; alternatively, the at least one second BWP information includes: the received second BWP information, and second BWP information having the first mapping relation with the first BWP information.

And (II) using the received second BWP information as BWP information used by the first communication device.

the at least one second BWP information is used as BWP information for the first communication device; or determining BWP information used by the first communication device according to the at least one second BWP information and a preset rule.

Indicating the first BWP information, the second BWP information is also changed according to an association relationship between the first BWP information and the second BWP information, and the BWP information used by the first communication device may be switched to the second BWP information associated with the first BWP information.

Here, the at least one second BWP information is used as BWP information for the first communication device, and may specifically include the following cases:

if the first BWP information is associated with one second BWP information, the BWP information used by the first communication device may be switched to the second BWP information associated with the first BWP information;

It should be noted that, the determining, according to the at least one second BWP information and the preset rule, the BWP information used by the first communication device may specifically be: the switching of the BWP information used by the first communication device to the second BWP information determined according to the preset rule may also be: the BWP information used by the first communication device is switched to at least one of the plurality of second BWP information signaled.

priority of the second BWP information;

The size of the data packet to be transmitted.

the second BWP information with the highest priority;

second BWP information with the lowest priority;

the second BWP information having the first priority.

the second BWP information with the largest number;

the second BWP information with the smallest number;

and the second BWP information numbered as the first number.

For example, when the configuration of the first BWP information is changed, the change of the configuration of the second BWP information may be implicitly indicated according to the mapping relationship between the first BWP information and the second BWP information, i.e., the configuration of the second BWP information associated with the first BWP information is changed according to the implicit indicated relationship. For example, when the first BWP information is configured as bwp_1, the configuration of the corresponding second BWP information is changed to bwp_3; when the configuration of the first BWP information is changed to bwp_2, the configuration of the corresponding second BWP information is also changed to bwp_4.

And (iii) predefining default second BWP information, that is, determining at least one of the predefined default second BWP information as BWP information used by the first communication device.

Optionally, the method further comprises:

In this embodiment, the terminal may determine BWP information used by the second communication device according to the received first BWP information and/or second BWP information, thereby solving the problem that the UE is likely to cause abnormal transmission due to the inability to timely learn about the change of the BWP of the base station.

As an optional embodiment of the present invention, the determining BWP information used by the second communication device according to the first BWP information and/or the second BWP information includes at least one of the following:

(1) And according to the received second BWP information and the second mapping relation, taking the first BWP information with the second mapping relation with the second BWP information as the BWP information used by the second communication device.

Here, that is, the case where the first BWP information implicitly associates the second BWP information, that is, the first BWP information implicitly associates the second BWP information through the second mapping relation. For example, the UE receives handover indication information of the second BWP information transmitted by the base station, and then the UE can determine the first BWP information associated with the second BWP information, that is, the BWP information used by the second communication device.

(2) And using the received first BWP information as BWP information used by the second communication device.

In this embodiment, the UE may perform the signal-based operation according to the acquired updated first BWP information (e.g., CSI-RS), i.e., the BWP information used by the second communication device, when the first BWP information is changed, by associating the first BWP information (implicitly or explicitly) with the second BWP information. For example, CSI-Report, channel estimation (channel estimation), channel tracking operation (channel tracking operation), etc., thereby solving the problems of UE link adaptation error (UE link adaptation error) caused by the original CSI-RS being processed due to the change of the first BWP information, channel estimation with white noise and time/frequency fine synchronization, etc.

In the embodiment of the invention, by receiving the configured associated (implicit or explicit) first BWP information and/or second BWP information, updated second BWP information can be acquired according to the first BWP information and/or the second BWP information when the base station BWP changes, so that the change of the base station BWP can be known in time, the problem that the UE is easy to cause abnormal transmission due to the fact that the change of the base station BWP cannot be known in time is solved, and network energy saving of the frequency domain BWP is realized.
