Description

Method, system and equipment for indicating uplink resource configuration

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a method, a system, and a device for indicating uplink resource configuration.

Background

In Long Term Evolution (LTE) and previous wireless communication systems, there is only one carrier under one base station (eNB), and the maximum bandwidth is 20MHz in LTE systems, as shown in fig. 1.

In an LTE Advanced (LTE-a) system, the peak rate of the system is greatly improved compared to the LTE system, and it is required to achieve 1Gbps downlink and 500Mbps uplink. The peak rate requirement cannot be achieved if only one carrier with a maximum bandwidth of 20MHz is used. Therefore, the LTE-a system needs to extend a bandwidth that can be used by a terminal, thereby introducing a Carrier Aggregation (CA) technology that aggregates a plurality of continuous or discontinuous carriers under the same eNB while serving the terminal (UE) to provide a required rate. Cells (cells) or component carriers under different enbs cannot be aggregated. In order to ensure that the UE in the LTE system can operate under each aggregated carrier, each carrier does not exceed 20MHz at maximum. The CA technology for LTE-A is shown in FIG. 2.

There are 4 carriers that can be aggregated under the base station of LTE-a shown in fig. 2, and the base station can perform data transmission with the UE on the 4 carriers simultaneously, so as to improve the system throughput.

In an LTE-a system, a UE can simultaneously aggregate multiple cells for signaling scheduling and traffic transmission. The current discussion regarding measurements defines the concepts of primary and secondary serving cells for multiple cells aggregated by a UE, corresponding to the primary carrier (PCC) and secondary carrier (SCC) currently aggregated by the UE, respectively. In the handover process, the UE can only initiate random access on the primary cell of the target eNB, while the secondary cell of the target eNB provides the resources required for carrier aggregation transmission. From the resource allocation perspective, the current configuration of some uplink resources, including resources for channel quality feedback (CQI), Dedicated Scheduling Request (DSR), and uplink hybrid automatic repeat request (HARQ) feedback, is limited to the primary cell. The choice of primary cell is UE-level, i.e. it is not required that all UEs in the system must use the same primary cell or cells on the same carrier. In addition, the uplink and downlink carriers constituting the primary carrier need to satisfy the correspondence relationship indicated in the system information SIB 2. The eNB may not configure uplink resources of the secondary cell, and only configure downlink resources for it.

In the CA system, some cell management processes (e.g., deleting a secondary cell, reconfiguring a secondary cell, activating/deactivating a secondary cell, reporting signal quality of a serving cell, etc.) need to frequently search for the aggregation cell of the UE. Cells within an aggregation range can be uniquely determined by frequency points and Physical Cell Identities (PCIs). From the point of view of signaling overhead, the cell number parameter can be introduced to avoid the heavy reuse of the two parameters, i.e. carrier frequency and PCI. The current standard discussion has decided to introduce the UE level cell number parameter, coded as 3 bits (bit), and the number of a cell will be assigned to the UE by the network at the same time as the cell is added.

Currently, uplink resources and downlink resources are configured for a secondary cell through a Radio Resource Control (RRC) connection reconfiguration message, and uplink resource related parameters appearing in the RRC connection reconfiguration message include:

an uplink carrier frequency (UL-CarrierFreq) parameter, an uplink Bandwidth (UL-Bandwidth) parameter, a PUSCH common configuration (PUSCH-ConfigCommon-r10) parameter, a Physical Uplink Shared Channel (PUSCH) common configuration sounding reference signal (soundgrs-UL-ConfigCommon-r 10) parameter, an uplink cyclic prefix length (UL-cyclic prefix length-r10) parameter, an uplink powercontrolcommon-r10 parameter, an uplink dedicated configuration sounding reference signal (soundgrs-UL-configdivided) parameter, and the like.

In the Access Service Network (ASN) protocol, an OPTIONAL (option) is noted after some Information Element (IE), meaning that this IE may or may not be present in the signaling. If the IE is present in the signaling, the UE uses the configuration value of the IE; if this IE is not present in the signaling, the UE's behavior needs to refer to the Need code noted after the OPTIONAL and the corresponding literal description in the protocol.

Currently, there are three kinds of Need codes:

the first method comprises the following steps: need OP, meaning that if the IE is not present in the signaling, the UE performs the behavior specified in the protocol procedure, or performs the behavior specified in the IE's domain description;

and the second method comprises the following steps: need ON, meaning that if the IE is not present in the signaling, the UE does not perform any operation, i.e., does not configure the IE, or continues to use the original value of the IE;

and the third is that: need OR, meaning that if the IE is not present in the signaling, the UE deletes OR stops using the current value of the IE.

Currently, the addition, modification and deletion of the secondary cell are all performed by RRC connection reconfiguration message, where the IE deleting the secondary cell is a cell deletion list (secCellToReleaseList-r 10). The list may include cell numbers (cell indexes), and the cells corresponding to these numbers are deleted. The IE for adding and modifying the secondary cell is a cell addition modification list (secCellToAddModList-r10), and the IE includes the cell number of the cell to be added or modified and the corresponding configuration parameters.

In the process of implementing the invention, the inventor finds that the following technical problems exist in the prior art: the LTE system is a single carrier system, the UE only operates in the serving cell, and the uplink and downlink resources of the primary cell are configured. However, for a system employing carrier aggregation technology, the eNB may configure downlink resources only for the secondary cell. In this case, how the terminal knows whether the network side configures or deletes the uplink resource of the secondary cell needs to be considered, and at present, there is no solution to this problem.

Detailed Description

In order to solve the problem how a terminal in a multi-carrier system knows whether a network side configures uplink resources or deletes uplink resource configuration of an auxiliary cell, an embodiment of the present invention provides an uplink resource configuration indication method in a multi-carrier system.

Referring to fig. 3, the method for indicating uplink resource configuration in a multi-carrier system according to the embodiment of the present invention specifically includes the following steps:

step 30: the base station determines whether uplink resources need to be configured for the auxiliary cell of the terminal or uplink resource configuration of the auxiliary cell of the terminal needs to be deleted;

step 31: and the base station indicates whether the terminal configures the uplink resource for the auxiliary cell or deletes the uplink resource configuration of the auxiliary cell according to the determination result.

Specifically, the base station determines whether to configure uplink resources for the secondary cell of the terminal; and indicating whether the terminal configures the uplink resource for the auxiliary cell according to the determination result. Or, the base station determines whether to delete the uplink resource of the secondary cell of the terminal; and when the determination result is yes, indicating the terminal to delete the uplink resource of the secondary cell.

The specific implementation of step 31 may be as follows:

firstly, a base station generates a resource allocation signaling according to a determination result and a setting rule, wherein the resource allocation signaling contains or does not contain a specific information element IE or the value of the specific IE is set as a set value;

and then, the base station sends the generated resource configuration signaling to the terminal so as to instruct the terminal to determine whether to configure uplink resources for the auxiliary cell or delete the uplink resource configuration of the auxiliary cell according to whether the resource configuration signaling contains the specific IE or the value of the specific IE.

Specifically, the following cases are classified:

the first condition is as follows:

if the specific IE is a preset indication IE for indicating whether to configure the uplink resource for the secondary cell or delete the uplink resource configuration for the secondary cell, when the base station determines that the uplink resource needs to be configured for the secondary cell of the terminal, the base station generates a resource configuration signaling according to a set rule, and specifically, the following three schemes can be adopted:

firstly, a base station generates a resource configuration signaling containing the specific IE and an uplink resource configuration parameter related IE;

secondly, the base station generates a resource configuration signaling containing the specific IE and an IE related to the uplink resource configuration parameter, and the value of the specific IE is set as a value for indicating the configuration of the uplink resource;

thirdly, the base station generates a resource configuration signaling which does not contain the specific IE and contains the IE related to the uplink resource configuration parameter.

Case two:

if the specific IE is a preset indication IE for indicating whether to configure the uplink resource for the secondary cell or delete the uplink resource configuration of the secondary cell, when the base station determines that the uplink resource does not need to be configured for the secondary cell of the terminal or the uplink resource configuration of the secondary cell of the terminal needs to be deleted, the base station generates a resource configuration signaling according to a set rule, and the following three schemes can be specifically adopted:

first, the base station generates a resource configuration signaling not containing the specific IE;

secondly, the base station generates a resource configuration signaling containing the specific IE, and the value of the specific IE is set as a value for indicating that uplink resources are not configured or deleted;

thirdly, the base station generates a resource configuration signaling containing the specific IE.

When the scheme is adopted, the resource configuration signaling may include an uplink resource configuration parameter related IE or may not include the uplink resource configuration parameter related IE.

When the base station determines that the uplink resource configuration of the secondary cell of the terminal needs to be deleted and generates a resource configuration signaling containing the specific IE, the specific IE may be located in a secondary cell deletion list in the resource configuration signaling.

The indication IE is an existing IE or a newly defined IE of the resource configuration signaling. The existing IEs in the resource configuration signaling are: IE not configured to secondary cell and configured to primary cell, i.e. primary cell dedicated IE.

Case three:

if the specific IE is an IE related to the uplink resource configuration parameter, when the base station determines that the uplink resource needs to be configured for the secondary cell of the terminal, the base station generates a resource configuration signaling according to a set rule, which may be specifically implemented as follows:

and the base station generates a resource configuration signaling containing the IE related to the uplink resource configuration parameter.

Case four:

if the specific IE is an IE related to the uplink resource configuration parameter, when the base station determines that the uplink resource does not need to be configured for the secondary cell of the terminal or the uplink resource configuration of the secondary cell of the terminal needs to be deleted, the base station generates a resource configuration signaling according to a set rule, which can be specifically implemented as follows:

and the base station generates a resource configuration signaling which does not contain the IE related to the uplink resource configuration parameter.

In the invention, after the base station indicates that the terminal does not configure the uplink resource for the auxiliary cell or deletes the uplink resource configuration of the auxiliary cell according to the determination result, the base station can configure the uplink resource for the terminal by adopting an increment delta configuration method according to the uplink resource configuration information stored by the terminal.

Referring to fig. 4, an embodiment of the present invention further provides an uplink resource allocation indication application method in an uplink multi-carrier system, which specifically includes the following steps:

step 40: the terminal receives an indication sent by the base station whether to configure uplink resources for the auxiliary cell of the terminal or delete the uplink resource configuration of the auxiliary cell of the terminal;

step 41: and the terminal determines whether to configure uplink resources for the auxiliary cell or delete the uplink resource configuration of the auxiliary cell according to the indication.

In step 40, the indication may be a resource configuration signaling, and then, the specific implementation of step 41 may be as follows:

and the terminal determines whether to configure uplink resources for the auxiliary cell or delete the uplink resource configuration of the auxiliary cell according to whether the resource configuration signaling contains the specific IE or the value of the specific IE.

Specifically, the following two cases are classified:

the first condition is as follows:

if the specific IE is a preset indication IE for indicating whether to configure uplink resources for the secondary cell or delete uplink resource configuration of the secondary cell, the terminal determines whether to configure uplink resources for the secondary cell or delete uplink resource configuration of the secondary cell, and the following three schemes can be adopted for specific implementation:

first, the terminal determines whether the resource configuration signaling includes the specific IE, if so, determines to configure the uplink resource for the secondary cell, otherwise, determines not to configure the uplink resource for the secondary cell or deletes the uplink resource configuration of the secondary cell. And when the resource configuration signaling does not contain the specific IE, if the terminal configures the uplink resource for the auxiliary cell, the terminal determines to delete the uplink resource configuration of the auxiliary cell, and if the terminal does not configure the uplink resource for the auxiliary cell, the terminal determines not to configure the uplink resource for the auxiliary cell.

And secondly, the terminal determines whether the value of the specific IE contained in the resource configuration signaling is a preset value used for indicating the configuration of the uplink resource, if so, determines to configure the uplink resource for the auxiliary cell, otherwise, determines not to configure the uplink resource for the auxiliary cell or deletes the uplink resource configuration of the auxiliary cell. When the value of the specific IE contained in the resource configuration signaling is not a preset value used for indicating the configuration of the uplink resource, if the terminal has configured the uplink resource for the auxiliary cell, the terminal determines to delete the uplink resource configuration of the auxiliary cell, and if the terminal has not configured the uplink resource for the auxiliary cell, the terminal determines not to configure the uplink resource for the auxiliary cell;

and thirdly, the terminal determines whether the resource configuration signaling contains the specific IE, if so, determines not to configure uplink resources for the auxiliary cell or delete the uplink resource configuration of the auxiliary cell, otherwise, determines to configure the uplink resources for the auxiliary cell.

In this scheme, if the resource configuration signaling carries an uplink resource configuration parameter related IE, after the terminal determines that the uplink resource is not configured for the secondary cell, the terminal may receive and store the uplink resource configuration parameter related IE information, and prohibit the uplink resource configuration parameter related IE from being applied; or the terminal stops receiving the IE information related to the uplink resource configuration parameter; or, after receiving the uplink resource configuration parameter related IE information, the terminal deletes the uplink resource configuration parameter related IE information.

If the resource configuration signaling carries an uplink resource configuration parameter related IE, the terminal may delete the existing uplink resource configuration of the secondary cell after the terminal determines to delete the uplink resource configuration of the secondary cell; or the terminal stores the existing uplink resource configuration IE information of the secondary cell and forbids to apply the IE related to the uplink resource configuration parameter.

After prohibiting the application of the IE related to the uplink resource configuration parameter, if the terminal receives the indication sent by the base station for configuring the uplink resource for the secondary cell again, the IE related to the uplink resource configuration parameter prohibited from being applied may be used to perform uplink resource configuration.

After prohibiting the application of the IE related to the uplink resource configuration parameter, if receiving uplink resource configuration information configured for the secondary cell by the base station using an incremental delta configuration method, the terminal configures the uplink resource for the secondary cell according to the uplink resource configuration information.

Case two:

if the specific IE is an IE related to the uplink resource configuration parameter, the terminal determines whether to configure the uplink resource for the secondary cell or delete the uplink resource configuration of the secondary cell, which may be specifically implemented as follows:

and the terminal determines whether the resource configuration signaling contains the uplink resource configuration parameter related IE, if so, determines to configure the uplink resource for the auxiliary cell, otherwise, determines not to configure the uplink resource for the auxiliary cell or deletes the uplink resource configuration of the auxiliary cell.

Preferably, in the present invention, after the terminal determines to configure the uplink resource for the secondary cell, a Radio Resource Control (RRC) layer of the terminal may notify a Media Access Control (MAC) layer to enable an uplink process of an uplink component carrier corresponding to the secondary cell.

After the terminal determines to delete the uplink resource configuration of the secondary cell, the RRC layer of the terminal notifies the MAC layer to reset a hybrid automatic repeat request (HARQ) process of the uplink component carrier corresponding to the secondary cell, and stops using the uplink component carrier.

The MAC layer resets the HARQ process of the uplink component carrier corresponding to the secondary cell, and specifically includes two steps: completely emptying buffers of all uplink HARQ processes of the uplink member carrier; and setting the new data indication NDI of all uplink HARQ processes of the uplink component carrier to be 0. The NDI is a new data transmission indication stored in an uplink process of the MAC layer, and the NDI is set to be 0 and then prohibits the uplink process from transmitting new data

The resource configuration signaling in the invention can be RRC dedicated signaling, MAC signaling and Physical Downlink Control Channel (PDCCH) signaling. The RRC dedicated signaling includes an RRC connection reconfiguration message, etc.

The invention is illustrated below with reference to specific examples:

the invention provides an indication method of uplink resources of a secondary cell, which has the core idea that: the eNB indicates whether the UE configures/deletes the uplink resource of the secondary cell in an explicit or implicit mode. The explicit indication mode is that an IE is newly defined or an existing IE is multiplexed to indicate whether the UE configures/deletes uplink resources in dedicated signaling (RRC connection reconfiguration message); the implicit indication method is to indicate whether to configure/delete uplink resources by using "option status" in asn.1. Three schemes are listed below, wherein the scheme one and the scheme two are explicit indications, and the scheme three is an implicit indication, specifically as follows:

the first scheme is as follows: multiplexing existing IEs

Multiplexing premise: the IE that is not associated with the secondary cell and must be configured to the primary cell may be multiplexed to indicate whether to configure/delete the uplink resource of the secondary cell.

The eNB explicitly indicates whether to configure/delete the uplink resource of the secondary cell by configuring or not configuring a certain multiplexing IE for the secondary cell (or by configuring a special value);

and the UE judges whether to configure/delete the uplink resource configuration of the cell according to the indication of the multiplexing IE in the secondary cell.

Scheme II: new definition IE

The disadvantage of multiplexing the existing IE to indicate the uplink resource configuration of the secondary cell is that the IE is given two meanings, which is easy to cause confusion. This problem does not occur if an IE is newly defined to indicate the secondary cell uplink resource configuration exclusively.

The eNB explicitly indicates whether to configure/delete the uplink resource of the secondary cell by configuring or not configuring some new defined IE for the secondary cell (or by configuring a special value);

and the UE judges whether to configure/delete the uplink resource configuration of the cell according to the indication of the newly defined IE in the secondary cell.

For the first and second schemes, although the eNB explicitly indicates whether to configure uplink resources for a certain secondary cell, the uplink resource configuration of the secondary cell may still occur in the RRC connection reconfiguration message configuring the secondary cell; meanwhile, if the UE determines that the eNB does not configure the uplink resource for a certain secondary cell, but the secondary cell configuration signaling includes the uplink resource configuration, the UE may select to reserve (but not apply) or not reserve the uplink resource configuration.

The third scheme is as follows: using OPTIONAL fragments

The eNB indicates whether to configure/delete the uplink resource of the secondary cell through the option status, that is, the eNB implicitly indicates whether to configure/delete the uplink resource of the secondary cell by whether to allow the uplink resource configuration to appear in the configuration of the secondary cell;

and the UE judges whether to configure/delete the uplink resource configuration of the cell according to the presence or absence of the uplink resource configuration in the auxiliary cell configuration.

Examples are given below:

the first embodiment is as follows:

in this embodiment, corresponding to the first scheme, when the base station only configures the downlink resource for the newly added secondary cell, an RRC connection reconfiguration message that does not include the specific IE and includes the uplink resource configuration information is sent to the terminal.

The specific IE may be an IE that is independent of the secondary cell and must be configured to the primary cell, such as: freqBandIndicator, plmn-IdentityList, si-WindowLength, systemInfo ValueTag, ac-BarringInfo, and the like. In this embodiment, freqBandIndicator is multiplexed as an example. The following method is used to indicate whether uplink resources are configured/deleted for a certain secondary cell: indicating whether freqBandIndicator exists or indicating by different values of freqBandIndicator (for example, a value of freqBandIndicator of 1 indicates that uplink resources need to be configured for the auxiliary cell, and a value of freqBandIndicator of not 1 indicates that the auxiliary cell has no uplink resources or deletes the uplink resources of the auxiliary cell). In this embodiment, it is taken as an example that occurrence of freqbandwidth indicator indicates that uplink resources need to be configured for the secondary cell, and non-occurrence of freqbandwidth indicator indicates that uplink resources are not configured for the secondary cell.

Suppose that two cells, namely cell 1 and cell 2, are operated by UE under a certain eNB in a converged manner, where cell 1 is a primary cell and cell 2 is a secondary cell. At this point, the eNB decides to configure a cell 3 containing only downlink resources (no uplink resources) for the UE. Then, the eNB issues an RRC connection reconfiguration message, and freqBandIndicator is located in a radio resource cell common configuration (radioresourceconfigcommonsercecell-r 10) IE in the message.

In the RRC connection reconfiguration message, the configuration information corresponding to the cell 3 does not include a freqbandwidth indicator, and includes uplink resource configuration information of the cell 3. After receiving the RRC reconfiguration message, the UE finds that the configuration information of the cell 3 does not include a freqbandwidth indicator, thereby determining that the eNB does not configure the uplink resource for the cell 3. At this time, the UE may have two behaviors:

the UE deletes the uplink resource configuration of cell 3. If the subsequent eNB needs to configure the uplink resource for the cell 3, the explicit mode is used for reconfiguration; or,

the UE receives the base station uplink resource configuration information on cell 3, but does not apply. If the subsequent eNB configures the uplink resource for the cell 3, the UE may directly use the existing configuration, or the eNB performs incremental (delta) configuration based on the existing uplink resource configuration of the UE, that is, the eNB configures the uplink resource for the UE by sending an RRC connection reconfiguration message only including the changed uplink resource configuration IE.

The configuration independent of the uplink resources of cell 3 is configured according to the existing procedure.

Note that, in the RRC connection reconfiguration message, the configuration information corresponding to the cell 3 may not include the freqbandwidth indicator, and may not include the uplink resource configuration information of the cell 3.

Example two:

in this embodiment, corresponding to the second scheme, when the base station needs to delete the uplink resource of the secondary cell in the configuration set, an RRC connection reconfiguration message containing the value of the specific IE as a set value and the uplink resource configuration information is sent to the terminal.

In this embodiment, a new IE is defined to indicate the uplink resource configuration of the secondary cell exclusively. Let the IE be named ul-presentationor type Boolean (bool). If the ul-presence indicator parameter of a certain secondary cell is "false", it indicates that the uplink resource configuration of the secondary cell is not configured/deleted, and the UE ignores any uplink resource configuration of the secondary cell; if the ul-presentationindicator parameter is "true", it indicates that the uplink resource configuration of the secondary cell is configured/reserved (it may also be indicated that the uplink resource configuration of the secondary cell is not configured/deleted by "true", and "false" indicates that the uplink resource configuration of the secondary cell is configured/reserved, depending on the meaning of the newly defined IE).

Suppose that three cells, namely cell 1, cell 2 and cell 3, are operated by the UE under a certain eNB in an aggregation manner, where cell 1 is a primary cell, the remaining two cells are secondary cells, and cell 3 has been configured with uplink resources. The numbers of the three cells are index1, index2, and index3, respectively. At this time, the eNB determines to delete the uplink resource allocation of the cell 3. Then, the eNB issues an RRC connection reconfiguration message, and for simplicity, it is assumed that the location of the ul-prcsencentidicator is the same as that of the freqBandIndicator in the first embodiment, and is also located in the radioresourceconfigcommonsercecell-r 10 in the RRC reconfiguration message.

In the RRC connection reconfiguration message, the ul-presence indicator value in the configuration information corresponding to the cell 3 is "false". After receiving the RRC connection reconfiguration message, the UE finds that the ul-presence indicator value in the configuration information of the cell 3 is "false", thereby determining that the eNB decides to delete the uplink resource configuration of the cell 3. At this time, the UE may have two behaviors:

the UE does not delete the uplink resource configuration information for cell 3 but is no longer applied. If the subsequent eNB reconfigures the uplink resource for the cell 3, the UE may directly use the reserved configuration, or the eNB may perform delta configuration based on the uplink resource configuration saved by the UE.

For the scenario described in this embodiment, the ul-presentationindicator may also be placed in the secondary cell deletion list in the RRC reconfiguration message instead of being placed in the above-mentioned location, that is, the ul-presentationindicator may be placed in the secondary cell deletion list in parallel with the index3 to represent that the uplink resource configuration of the cell 3 is deleted.

Example three:

in this embodiment, corresponding to the second scheme, when configuring the uplink resource for the secondary cell in the configuration set, an RRC connection reconfiguration message that includes the specific IE and includes the uplink resource configuration information is sent to the terminal.

Suppose that three cells, namely cell 1, cell 2 and cell 3, are operated by the UE under a certain eNB in an aggregation manner, where cell 1 is a primary cell, the other two cells are secondary cells, and cell 3 is not configured with uplink resources. At this time, the eNB determines to allocate uplink resources for the cell 3. Then, the eNB issues an RRC connection reconfiguration message, where the message includes uplink resource configuration of the cell 3, and the value of ul-presentationindicator is "true". After receiving the RRC connection reconfiguration message, the UE finds that the ul-presence indicator value in the configuration information of the cell 3 is "true", thereby determining that the eNB determines to configure the uplink resource for the cell 3. At this time, the UE configures the parameters related to the uplink resource according to the uplink resource configuration information in the RRC reconfiguration message.

Example four:

in this embodiment, corresponding to the second scheme, when the base station needs to configure downlink resources only for the newly added secondary cell, an RRC connection reconfiguration message that includes the specific IE and does not include uplink resource configuration information is sent to the terminal.

Suppose that two cells, namely cell 1 and cell 2, are operated by UE under a certain eNB in a converged manner, where cell 1 is a primary cell and cell 2 is a secondary cell. At this point, the eNB decides to configure a cell 3 containing only downlink resources (no uplink resources) for the UE. Then, the eNB issues an RRC connection reconfiguration message, where the message does not include the uplink resource configuration of the cell 3, and the ul-presentationindicator value is "true". After receiving the RRC connection reconfiguration message, the UE finds that the ul-presence indicator value in the configuration information of the cell 3 is "true", thereby determining that the eNB does not configure the uplink resource for the cell 3. At this time, the UE configures parameters unrelated to the uplink resource of the cell 3 according to the existing process.

Example five:

in this embodiment, corresponding to the third scheme, when the base station needs to delete the uplink resource of the secondary cell in the configuration set, the RRC connection reconfiguration message that does not include the uplink resource configuration information is sent to the terminal.

For the third scheme, the domain description of the IE related to the uplink resource configuration of the secondary cell should be first explicit. Currently, the ul-CarrierFreq and ul-Bandwidth domains are described as follows:

ul-Carrier Freq: for a Frequency Division Duplex (FDD) system, if the IE does not occur, a default transmit/receive frequency interval is employed; for a Time Division Duplex (TDD) system, if the IE is not present, the value is equal to the downlink frequency.

ul-Bandwidth: for an FDD system, if the IE does not appear, the uplink bandwidth adopts the same value as the downlink bandwidth; for TDD systems, this IE is always absent and the uplink and downlink bandwidths take the same value.

For this scheme, it is desirable that the UE does not use any value when a certain uplink resource configuration does not occur, rather than using a default value. Therefore, the domain descriptions of the two IEs need to be modified and deleted. Meanwhile, the Need codes of the two IEs are set to Need OR.

The field description of other uplink resource configurations is not yet defined, and therefore, the simplest method is to set their Need codes to Need OR as well. For the scene without configuring/deleting the uplink resource, the uplink resource configuration related IE does not appear in the RRC reconfiguration message; these IEs would then appear for the scenario where uplink resources are configured.

Suppose that three cells, namely cell 1, cell 2 and cell 3, are operated by the UE under a certain eNB in an aggregation manner, where cell 1 is a primary cell, the remaining two cells are secondary cells, and cell 3 has been configured with uplink resources. At this time, the eNB determines to delete the uplink resource allocation of the cell 3. Then, the eNB issues an RRC connection reconfiguration message, wherein the message does not contain IE related to the uplink resource configuration. After receiving the RRC connection reconfiguration message, the UE finds that there is no uplink resource configuration information in the configuration information of the cell 3, thereby determining that the eNB decides to delete the uplink resource configuration of the cell 3, and the UE performs an operation of deleting the uplink resource configuration.

The disadvantage of this approach is that the domain descriptions of existing IEs need to be modified, which may cause compatibility issues, making the understanding of these IEs by the Rel-8UE ambiguous (e.g., still understood in terms of the original domain descriptions), resulting in erroneous UE behavior.

To avoid this problem, a method of adding description to the existing IE field description may be adopted, specifically as follows:

ul-Carrier Freq: for FDD systems, if the IE is not present, a default transmit/receive frequency interval is employed; for a TDD system, if the IE is not present, the value is equal to the downlink frequency. If all the uplink resource configurations do not appear, the UE does not configure the IE or delete the configuration of the IE;

ul-Bandwidth: for an FDD system, if the IE does not appear, the uplink bandwidth adopts the same value as the downlink bandwidth; for TDD systems, this IE is always absent and the uplink and downlink bandwidths take the same value. If all the uplink resource configurations do not appear, the UE does not configure the IE or delete the configuration of the IE;

following the modification of the above two IE domain descriptions, the domain descriptions of other uplink resource configurations are also supplemented with a UE behavior description of "if all uplink resource configurations do not appear, the UE does not configure the IE or deletes the configuration of the IE". Then, the Need code of each uplink resource configuration IE is set to Need OP. The specific behaviors of the UE and the eNB are consistent with those of the first half in this embodiment, and are not described again.
