Background

Currently, a protocol defines multiple candidate values of a period of a resource of an unlicensed scheduling/grant free cg/GF and a semi-persistent scheduling (SPS), and for a specific service, a period of a matched resource may be selected according to the period of the service, so that data may be transmitted and received between a terminal device and a network device for the service of the terminal device according to the period of the selected resource. For example, when the periodic candidate values for the resource include: a. b, c, d, etc., if the period of the service is a, the period of the resource configured for the service by the network device is a, and if the period of the service is b, the period of the resource configured for the service by the network device is b.

The problems of the method are as follows: because the candidate value of the period of the resource is limited, the period of the service may not have a corresponding period of the resource, that is, the period of the service does not match the period of the resource, at this time, there is a deviation between the period of the service and the period of the resource, and the deviation becomes larger and larger as time goes by, which causes that the time delay becomes larger when the terminal device receives and transmits the service each time, and the communication efficiency is reduced.

The network device and the terminal device may operate on a New Radio (NR) communication system, and the terminal device may communicate with the network device through the NR communication system.

Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiation Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), tablet computers (pads), and computers with wireless transceiving functions. A wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a Mobile Station (MS), a remote station (remote station), an Access Point (AP), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), a Subscriber Station (SS), a user terminal device (CPE), a terminal (terminal), a User Equipment (UE), a Mobile Terminal (MT), etc. The wireless terminal device may also be a wearable device and a next generation communication system, for example, a terminal device in a 5G network or a terminal device in a Public Land Mobile Network (PLMN) network for future evolution, a terminal device in an NR communication system, etc.

A network device is an entity, such as a new generation base station (gdnodeb), in a network side for transmitting or receiving signals. The network device may be a device for communicating with the mobile device. The network device may be an AP in a Wireless Local Area Network (WLAN), a Base Transceiver Station (BTS) in a global system for mobile communications (GSM) or Code Division Multiple Access (CDMA), a base station (NodeB, NB) in a Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB, or eNodeB) in a Long Term Evolution (LTE), or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device in a future 5G network or a network device in a future evolved Public Land Mobile Network (PLMN), or a network device in an NR system, etc. In addition, in this embodiment of the present application, a network device provides a service for a cell, and a terminal device communicates with the network device through a transmission resource (for example, a frequency domain resource or a spectrum resource) used by the cell, where the cell may be a cell corresponding to the network device (for example, a base station), and the cell may belong to a macro base station or a base station corresponding to a small cell (smallcell), where the small cell may include: urban cells (Metro cells), Micro cells (Micro cells), Pico cells (Pico cells), Femto cells (Femto cells), and the like, and the small cells have the characteristics of small coverage area and low transmission power, and are suitable for providing high-rate data transmission services. Furthermore, the network device may be other means for providing wireless communication functionality for the terminal device, where possible. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices. For convenience of description, in the embodiments of the present application, an apparatus for providing a wireless communication function for a terminal device is referred to as a network device.

Wireless communication technology has penetrated many traditional industries and has spawned many emerging applications such as autopilot, telemedicine, smart robots, and the like. An intelligent robot is an important application in the field of modern industrial control, and not only is a communication network of the robot required to achieve a low-delay and high-reliability data transmission function, but also unified and standard clock information needs to be obtained from the communication network so as to ensure cooperative work among the robots. Currently, in some high-precision industrial control fields, the absolute clock deviation between robots is required to be within 1 microsecond (us), that is, the robots operate simultaneously based on instructions, such as simultaneously carrying a certain part, or 2 robot arms lifting the part, and other arms performing operations such as welding, painting and the like.

The current standard discusses a method of periodically interacting TSN related information between a network device and a terminal device, where the information may be transmitted on configured scheduled (CG) resources or SPS (semi-persistent scheduling) resources, where CG is currently applied in uplink and SPS is in downlink.

In NR, uplink transmission is classified into the following three types:

1. uplink transmission based on dynamic grant (grant).

That is, uplink scheduling information (UL grant in a DCI) is transmitted in the downlink control information.

2. There is no uplink transmission of the dynamic grant.

Uplink transmission without a dynamic grant is also referred to as a Configured Grant (CG) or a Grant Free (GF).

The uplink transmission modes are divided into the following two types:

2.1、Configured grant Type1

the Type1 is semi-persistent scheduling (SPS), and specifically, the terminal device receives a higher layer parameter configurable grant configuration including a rrc-configurable uplink grant, and does not need to receive DCI, and is called "configured uplink grant" in the protocol.

After receiving the parameters configured by the high layer, the terminal device can send data information on the time frequency resources configured periodically.

2.2、Configured grant Type2

The Type2 is similar to SPS in LTE, and the terminal device receives a higher layer parameter configuredturnconfig that does not include a rrc-configurable uplink grant, and then is activated or deactivated by L1 signaling, which is called "configurable dual link grant based on L1 signaling".

And the terminal equipment receives the parameters of the high-level configuration and receives the activation instruction in the DCI, and then the terminal equipment can send data information on the time-frequency resources configured periodically.

In NR, downlink transmission is divided into two types:

1. downlink transmission based on dynamic grant (grant)

That is, Downlink scheduling information (DL grant in a DCI) is transmitted in Downlink Control Information (DCI).

2. Semi-Persistent Scheduling (SPS)

The SPS is similar to Configured grant Type2 in uplink transmission, and some parameters are Configured through higher layer signaling, and then activated by DCI.

For a Time Sensitive Network (TSN), traffic of the TSN arrives periodically, but the period of the traffic may not be completely matched with the resource period configured by the current protocol.

The value ranges of the resource periods of the uplink CG given by the current NR protocol are shown in table 1:

table 1 value ranges of resource periods of uplink CG

The resource period of the downlink CG given by the current NR protocol is a minimum of 10ms, which may be subsequently reduced to 1 slot (slot) or less.

For the periods of the various resources given by the above protocol, there may be a case that the period of the service cannot be found in the value range of the period of the resources given by the protocol (or referred to as the candidate value of the period of the resources). For example, when the period of the service is 3 symbols or 16.67ms, the value range of the period of the resource does not have 3 symbols or 16.67 ms.

In view of the above problems, the solutions presented so far include:

1) a period for configuring smaller resources.

The method has the defects that: may result in a waste of resources. This is wasteful of resources because the method may require that the periodicity of the resources be configured to be very small so that the periodicity of the traffic can be matched.

For example, the period of a service is 6 slots, and a resource period of 1 slot may be required to meet the requirement, which is equivalent to that 6 resources are configured in each service period. In addition, the network device or the terminal device needs to detect data frequently, because the CG/SPS is semi-persistent scheduling, the transmitting end does not need to schedule signaling but transmits data on periodic resources configured in advance every time, and does not transmit data if the transmitting end has no traffic. However, due to the semi-static configuration, the receiving end cannot predict whether the transmitting end has data to transmit, so blind detection of data on the corresponding configuration resource is required, which wastes power consumption and resources.

2) And adopting the periodic joint configuration of a plurality of sets of resources.

This method also has resource waste and power consumption problems. For example, the period of a service is 3 slots, in order to match, it may be necessary to configure 2 sets of resources having a period of 2 slots, and the two sets of resources are staggered by one slot, so that the 2 sets of resources having a period of 2 slots may be combined to obtain a resource configuration having a period of 1 slot. Therefore, when the period of the service is 3 slots, 3 parts of resources are configured in the period of each service, which also results in waste of power consumption and resources.

Also, the period of the minimum resource in method 2) is also symbol-based, and if the period of the service is an integer multiple of a non-symbol, such as 0.833ms or 16.6667ms, then the method 2) may not be able to find the period of the appropriate resource.

In summary, neither of the two implementation methods can solve the problem that the service period is not matched with the resource period. Moreover, with the periodic transmission of the service, the deviation between the service and the resource will be accumulated continuously, so that the delay requirement of the service cannot be met.

In order to solve the above problems, the present application provides various methods for determining resources, and the general idea of the solution provided by the present application is: and dynamically adjusting the use time of the resource so that the arrival time of the service can be matched with the adjusted use time of the resource. The term "matching" in this application may refer to overlapping, that is, the arrival time of the service overlaps the use time of the adjusted resource, or may refer to "within a preset error range", that is, the difference between the arrival time of the service and the use time of the adjusted resource is smaller than a preset error/deviation.

In the present application, as an implementation method, when there is no period that is the same as a period of a service in a period of candidate resources (i.e., a value range of the period of the resource, or a candidate value of the period of the resource), the present application may select a period of a resource that is closest to the period of the service from the periods of the candidate resources as the period of the resource corresponding to the service. For example, a minimum period greater than the period of the service may be selected from the periods of the candidate resources, or a maximum period less than the period of the service may be selected from the periods of the candidate resources.

For convenience of description, the present application takes an example of selecting a minimum period from the periods of the candidate resources, which is greater than the period of the service.

Fig. 2 is a diagram illustrating an exemplary relationship between a period of a resource and a period of a service provided by the present application. Wherein, the period of the service is Pt, the period of the resource is P, and P-Pt is d. The period P of the resource is the minimum period which is larger than the period of the service in the periods of the candidate multiple resources. Since the period Pt of the traffic and the period P of the resource are both constant values, the difference d between them is also constant value.

When the first service arrives, the use time of the resource is matched with (or overlapped with) the arrival time of the service, so that the terminal equipment can directly use the resource at the time of R1;

when the second service arrives, the resource use time does not yet arrive, and the terminal device waits for the time length d before the resource use time arrives (i.e., at the time point R2), so that the cumulative value of the deviation between the service arrival time and the resource use time is d;

when the third service arrives, the resource use time has not yet arrived, and the terminal device waits for the time duration 2d before the resource use time arrives (i.e., at the time R3), so that the cumulative value of the deviation between the service arrival time and the resource use time is 2 d;

when the fourth service arrives, the resource use time has not yet arrived, and the terminal device waits for the time length 3d before the resource use time arrives (i.e., the time point R4), so that the cumulative value of the deviation between the service arrival time and the resource use time is 3 d;

when the fifth service arrives, the resource use time has not yet arrived, and the terminal device waits for the duration 4d before the resource use time arrives (i.e., at the time R5), so that the cumulative value of the deviation between the service arrival time and the resource use time is 4 d;

when the sixth service arrives, the resource use time has not yet arrived, and the terminal device waits for the time duration 5d before the resource use time arrives (i.e., the time R6), so that the cumulative value of the deviation between the service arrival time and the resource use time is 5 d;

and so on.

Therefore, as time increases, the cumulative value of the deviation between the arrival time of traffic and the usage time of resources becomes larger. Therefore, the implementation method provided by the application comprises the following steps: and when the accumulated value of the deviation between the service arrival time and the resource use time is greater than a preset deviation threshold value, adjusting the resource use time to enable the service arrival time of the terminal equipment to be matched with the resource use time.

Fig. 3 is a schematic diagram of a method for determining resources. The method is performed by a communication device, which may be a terminal device or a network device. That is, the network device and the terminal device both execute the method shown in fig. 3, so that the terminal device and the network device make the same adjustment on the usage time of the resource, so as to ensure the correctness of the communication between the terminal device and the network device.

The method comprises the following steps:

step 301, the communication device adjusts the service time of the resource according to the adjustment value, so that the service arrival time of the terminal device matches with the service time of the resource.

The service is a periodic service, and the resource is a periodic resource.

Step 302, the communication device determines transmission resources for the service according to the adjusted service time of the resources.

Based on the scheme, the communication equipment enables the service arrival time of the terminal equipment to be matched with the service time of the resource by adjusting the service time of the resource, so that the service arrival time of the terminal equipment can be matched with the service time of the resource, the delay time of waiting for the resource by the terminal equipment is reduced, and the communication efficiency between the terminal equipment and the network equipment is improved.

Various different implementations of the embodiment of fig. 3 are given below, and are described separately below.

The implementation method 1, the terminal device and the network device are independently adjusted respectively.

Based on the implementation method, if the communication device in the embodiment of fig. 3 is a terminal device, before step 301, if the terminal device determines that an accumulated value of a deviation between an arrival time of a service of the terminal device and a usage time of a resource configured by the network device is greater than a deviation threshold, the terminal device determines the adjustment value according to the accumulated value.

For example, referring to fig. 2, if the preset deviation threshold is 3.5d, the network device and the terminal device may expect that when the fifth traffic arrives, the cumulative value of the deviation between the arrival time of the traffic of the terminal device at this time and the usage time of the resource configured by the network device is determined to be equal to 4d and thus greater than the deviation threshold, and thus the terminal device is triggered to determine the above adjustment value according to the cumulative value. For example, when the accumulated value is an integer multiple of a symbol or a slot, the accumulated value may be used as an adjustment value; for another example, when the accumulated value is not a symbol or not an integer multiple of a slot, the accumulated value may be slightly processed, such as rounded to an integer multiple of a symbol or an integer multiple of a slot, to obtain an adjustment value.

Or, the adjustment may be performed after the accumulated value of the deviation exceeds the preset deviation threshold, for example, after the fifth accumulated deviation value reaches 4d and exceeds the preset threshold 3.5d, the usage time of the resource corresponding to the sixth service is adjusted.

For example, referring to fig. 2, the resource occurrence time R5 may be adjusted forward by an adjustment value (denoted by R in fig. 2) so that the adjusted usage time of the resource is R5', even if the arrival time of the traffic of the terminal device matches the usage time of the resource. Therefore, the terminal equipment does not need to wait, can quickly use resources to receive and transmit data, and can reduce time delay and improve communication efficiency.

Alternatively, the preset deviation threshold may be pre-configured, or protocol predefined. Specifically, the determination of the deviation threshold may be network device determination, and configured to the terminal device in advance through a signaling; the terminal device and the network device may also be determined according to the delay requirement of the service, for example, the deviation threshold is equal to the delay requirement of the service, or the deviation threshold is equal to half of the delay requirement of the service, or the maximum value of the error value of the hardware device is subtracted from the delay requirement. The delay requirement may be a maximum waiting time for the receiving end to wait for receiving the data sent by the sending end.

Based on the scheme, the method for the terminal device to adjust the use time of the resource according to the adjustment value includes, but is not limited to, the following methods:

in the method 1, the terminal equipment adjusts the service time of the resource within a preset time range according to the adjustment value, so that the service arrival time of the terminal equipment is matched with the service time of the resource.

And 2, the terminal equipment adjusts the service time of the resource before or after the appointed subsequent Nth service arrives according to the adjustment value, wherein N is a positive integer, so that the service arrival time of the terminal equipment is matched with the service time of the resource.

Namely, the use time of the resource corresponding to the Nth service or the (N +1) th service or the (N-1) th service is adjusted.

For example, if N is 1, the terminal device adjusts the resource usage time before the appointed subsequent 1 st service arrives according to the adjustment value. For another example, if N is 2, the terminal device adjusts the resource usage time before the appointed subsequent 2 nd service arrives according to the adjustment value, and so on.

And 3, after the terminal equipment determines the adjustment value, triggering the terminal equipment to start a pre-configured timer, and adjusting the service time of the resource by the terminal equipment before the timer times out according to the adjustment value, or adjusting the service time of the first resource after the timer times out according to the adjustment value so that the service arrival time of the terminal equipment is matched with the service time of the resource.

For the network device, the same method as the terminal device is also used to adjust the service time of the resource, so that the service arrival time of the terminal device is matched with the service time of the resource. Reference may be made to the foregoing description without further elaboration.

And the implementation method 2 is that the network equipment autonomously adjusts and informs the terminal equipment of corresponding adjustment.

Based on the method, the network equipment can acquire the service attributes of each service in advance, such as the service period and the like, so that the network equipment can be adjusted autonomously and inform the terminal equipment of corresponding adjustment.

For a specific implementation method for the autonomous adjustment of the network device, reference may be made to the adjustment method of the network device in the implementation method 1, which is not described again.

And for the terminal equipment, the network equipment notifies the terminal equipment of adjustment. Specifically, when the network device determines that the usage time of the resource needs to be adjusted, for example, if the network device determines that an accumulated value of a deviation between an arrival time of a service of the terminal device and the usage time of the resource configured by the network device is greater than a deviation threshold, the network device determines an adjustment value according to the accumulated value, and notifies the terminal device to adjust according to the adjustment value.

Optionally, the network device sends a notification signaling to the terminal device, where the notification signaling is used to notify the terminal device to adjust the resource usage time. The notification signaling may be DCI, or a medium access Control element (MAC CE), or Radio Resource Control (RRC) signaling.

Optionally, the notification signaling indicates the adjustment value, and the implementation method of the notification signaling indicating the adjustment value includes, but is not limited to, the following methods:

method 1, the notification signaling includes the above adjustment value.

For example, the adjustment value is, for example, 2,4, etc., and the unit may be symbol, slot, millisecond, microsecond, etc.

Method 2, the notification signaling comprises indication information, the indication information is used for indicating one of a plurality of predefined adjustment values.

For example, the terminal device presets or the network device pre-configures (e.g., semi-statically configures) a plurality of candidate adjustment values to the terminal device, and the notification signaling indicates different adjustment values through different values (i.e., bit states) of the indication information. For example, the indication information is 2 bits, and four adjustment values of 0, 2 symbols, 4 symbols, and 8 symbols are configured in the higher layer, and the specific values (i.e., adjustment values) that the network device expects the terminal device to adjust can be indicated by using the indication information as 00,01,10, and 11, respectively. Of course, the network device also adjusts according to the same adjustment value.

Method 3, the network device does not inform the adjustment value.

In the method, the terminal equipment and the network equipment decide the same calculation method of the adjustment value in advance, and after receiving the notification signaling, the terminal equipment is triggered to calculate the adjustment value and adjust the service time of the resource according to the adjustment value.

Optionally, the notification signaling may include 1-bit information, and when the terminal device determines that the 1-bit information is "1", the terminal device is triggered to calculate an adjustment value, and adjust the use time of the resource according to the adjustment value.

Optionally, based on any implementation method of the foregoing indication adjustment value, the notification signaling may further include an identifier of one or more terminal devices. Or, the notification signaling includes a terminal group identifier, where the terminal group identifier is used to indicate a terminal group, and the terminal group includes one or more terminal devices. For example, different Identifiers (IDs) are used to identify different terminal devices, different terminal group identifiers are used to identify different terminal groups, or different signaling resource locations are configured to distinguish different terminal devices or terminal groups.

The adjustment signaling may notify the terminal devices in a terminal group to adjust according to the same adjustment value, or the adjustment signaling may also notify different terminal devices in the terminal group to adjust according to different adjustment values. For example, with the method 2, the adjustment signaling includes indication information, and when the indication information is "11", different terminal devices understand that "11" is different, for example, the terminal device 1 understands that the adjustment value corresponding to "11" is 3 symbols, and the terminal device 2 understands that the adjustment value corresponding to "11" is 5 symbols, and so on, thereby implementing that one adjustment signaling indicates that different terminal devices adjust according to different adjustment values.

Based on the implementation method 2, after receiving the notification signaling, the terminal device adjusts the use time of the resource according to the adjustment value, and the specific method includes, but is not limited to, the following methods:

the method 1 comprises the step that the terminal equipment adjusts the service time of the resources within a preset time range according to the adjustment value.

And 2, the terminal equipment adjusts the service time of the resource before or after the appointed subsequent Nth service arrives according to the adjustment value, wherein N is a positive integer.

The resource may be a resource corresponding to the nth service, may also be a resource corresponding to the N-1 st service, and may also be a resource corresponding to the N +1 st service.

Method 3, notifying that the signaling includes adjusting time; the communication device adjusts the usage time of the resource within the adjustment time according to the adjustment value.

And 4, after receiving the notification signaling, the terminal equipment starts a pre-configured timer, and adjusts the service time of the resource before the timeout of the timer according to the adjustment value, or adjusts the service time of the first resource after the timeout of the timer according to the adjustment value.

A specific implementation of the implementation method 2 is given below.

For example, the notification signaling is a DCI. Currently, both the CG type2 and the SPS activation/deactivation are performed by using DCI, and in a specific protocol, some information fields are set to be fixed values through the following table 2 to transfer messages, and the terminal device is notified of activation, for example, one or more fields are set to all "0"; and, through the following table 3, messages are delivered with certain information fields set to fixed values, which have informed the terminal device to deactivate, such as one or more fields all set to "0" or "1".

As shown in table 2, is an active table. As shown in table 3, is a table of deactivations.

Table 2 activated form

Table 3 table of deactivation

From table 2, it can be seen that when all bits in DCI for indicating retransmission process number and redundancy version are set to "0", it indicates that the DCI is used for indicating terminal device activation.

From table 3, it can be seen that, when all bits used for indicating the retransmission process number and the redundancy version in the DCI are set to "0" and all bits used for indicating the modulation coding scheme and the frequency domain resource allocation are set to "1", it indicates that the DCI is used for indicating the terminal device to deactivate.

Based on the existing definitions, the following table 4 may be added to the present application, where the table 4 is used to instruct the terminal device to adjust the usage time of the resource.

TABLE 4 indication of adjustment of usage time of resources

Based on table 4, the present application is defined as follows: when all bits used for indicating retransmission process number, redundancy version, modulation coding mode and frequency domain resource allocation in the DCI are set to "0", it indicates that the DCI is used for indicating the terminal device to adjust the use time of the resource.

Based on table 4, the adjustment value of the usage time of the resource may be indicated by using a time domain resource allocation field (time domain resource allocation) in the DCI.

At present, a method for indicating time domain resources pre-configures multiple groups (at most 16 groups) of information for a high layer, where each group of information can indicate slot offset (time offset between DCI and data, that is, how many slots transmit data information after DCI is received), a start symbol in a slot, and duration of information transmission. When the base station actually schedules, it indicates which set of preconfigured information (4 bits at most) is used in the time domain resource allocation field of the DCI. The invention can multiplex the indication field (4 bits) to indicate the adjustment value:

method 1, multiplexing the existing indication method, the time domain resource allocation field of the DCI indicates the time information of the next data transmission after receiving the DCI, and other information, such as frequency domain resource, period, Modulation and Coding Scheme (MCS), continues to use the previous indication without change. Of course, the DCI type may also be indicated in a field such as a frequency resource, an MCS, or the like, by a new value or a corresponding frequency/MCS modulation value, and a fixed value of other information is used for indicating the DCI type, which is not limited herein.

Based on this method, the information indicated by the time domain resource allocation field of the DCI may indicate the adjusted time position of the used resource, and the unit may be a symbol, a slot, or the like.

That is, the method may indicate one of 16 time positions through a time domain resource allocation field of DCI and take the position as an adjusted time position of using a resource.

Method 2, because the time domain resource allocation domain of the DCI is 4bits, it may be defined to indicate that a slot may be indicated using 2 bits of the 4bits, and 2 bits indicate a symbol, so that 4bits constitute an adjustment value; or 4bits are used for indicating symbols; or 3 bits for indicating slots, 1 bit for indicating symbols, etc. Or 1 bit of the 4bits is used to indicate that the adjustment value is a negative value or a positive value, i.e., whether the adjustment value is adjusted forward or backward, and 3 bits of the 4bits are used to indicate the adjustment value.

Based on the method, a specific adjustment value is carried in a time domain resource allocation domain of the DCI.

In the method 3, since the time domain resource allocation domain of the DCI is 4bits, values of 16 adjustment values can be predefined, and then one of the 16 adjustment values is indicated by the 4 bits.

The implementation method 3 is that the network device performs adjustment based on the trigger of the terminal device and notifies the terminal device to perform corresponding adjustment.

This implementation method 3 is similar to the implementation method 2 described above, but differs therefrom in that: for the uplink TSN data transmission, the network device does not know the period of the traffic of the terminal device, or the network device cannot accurately obtain the deviation value between the resource used by the network device and the arrival time of the traffic due to the jitter of the arrival time of the traffic of the terminal device (for example, the clock of the terminal device has a deviation), so the network device cannot accurately obtain the above adjustment value.

Therefore, in implementation method 3, on the basis of implementation method 2, before the network device determines the adjustment value, the terminal device determines an adjustment reference value, and then sends the adjustment reference value to the network device, where the adjustment reference value is used to assist the network device in determining the adjustment value, that is, the network device may determine the adjustment value according to the adjustment reference value.

The terminal device may determine the adjustment reference value by the following method: when the terminal equipment determines that the accumulated value of the deviation between the arrival time of the service and the use time of the resource is greater than a preset deviation threshold value, the accumulated value at the moment is used as an adjustment reference value, or the adjustment value is obtained according to the accumulated value and is used as the adjustment reference value. The other parts of the implementation method 3 are the same as the implementation method 2, and reference can be made to the foregoing description.

Or, in another implementation method, the terminal device may send an uplink signaling to the network device instead of sending the adjustment reference value, so as to trigger the network device to adjust or reconfigure the resource usage time, and after receiving the uplink signaling, the network device may adjust the resource usage time of the network device according to the method of the implementation method described above, and notify the terminal device to adjust the resource usage time.

In addition, the present application also provides another implementation method 4 for solving the background problem, and the implementation method 4 is different from the embodiment of fig. 3 and the implementation methods 1 to 3.

And 4, realizing the method 4 and increasing the scaling factor.

The current resource period allocation method has a problem of resource waste because there may not be a period of the resource that is the same as the period of the traffic in the candidate values of the period of the resource, and if only a simple candidate value of the period of the current resource is added with more candidate values of the period of the resource, the total number of the candidate values of the period of the resource is more, which needs more bits to indicate the information. For example, when the periodic candidate value of the resource is 8, a 3-bit indication is required; when the periodic candidate for a resource is 9-16, then a 4-bit indication is required, and so on.

Based on this, in the implementation method 4 of the present application, on the basis of the candidate value of the period of the existing resource, the candidate value of the period of the resource is not increased any more, but when there is no period matching the period of the service of the terminal device in the candidate value of the period of the resource, a scaling factor is added to indicate the period of the resource selected for the service of the terminal device.

For example, the period of the service is 6 slots, and the candidate value of the period of the resource corresponding to 15kHz includes: 2,7, n × 14, where n ═ 1,2,4,5,8,10,16,20,32,40,64,80,128,160,320,640}, where it can be found that there is no period of 6 slots in the candidate values of the period of the resource, the period in which the network device can configure the resource for the terminal device is 2 slots, and it is determined that the scaling factor is equal to 3, so that the network device sends the period of the resource (value of 2 slots) and the scaling factor (value of 3) to the terminal device through the DCI, and then the period in which the terminal device can calculate the actual resource configured by the network device is: 2slot 3 ═ 6 slot. That is, in this example, the period of the resource actually configured for the terminal device by the network device is 6 slots, and the terminal device is notified by the period of the resource being 2 slots and the scaling factor being 3.

The scaling factor may be an integer value, such as 3, or may be a decimal value, such as 0.5.

The network device may carry the scaling factor in the signaling of the period of the resource configured for the terminal device, or may carry the scaling factor in an independent signaling, or may carry the scaling factor in a higher layer signaling or a dynamic signaling.

The implementation method does not need to increase the candidate value of the period of the resource, and can realize configuring more adaptive period values for the terminal equipment. Therefore, the period of configuring proper resources for the terminal equipment is realized on the premise of not obviously increasing signaling overhead.
