Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
In NR version 16 (Rel-16), it has been supported that one cell can deploy multiple TRansmission points (TRPs) to serve terminals at the same time. In the Beam Failure Recovery based on multiple TRPs, at most 2 SR resources have been configured for multiple TRPs through support, and a terminal applies for resources to send a BFR (Beam Failure Recovery) MAC-CE for the multiple TRPs, respectively. For example, the spatial relationship of the 2 SR resources is beams pointing to two TRPs, respectively, and when one TRP fails, the terminal may select to send an LRR (Link Recovery Request) to the TRP that does not fail, so as to increase the transmission reliability of the LRR and reduce the delay of transmission failure Recovery.
However, a cell group may contain multiple cells, some may have only one TRP, and some may have multiple TRPs; the terminal of some cells does TRP level beam failure report, the terminal of some cells does cell level beam failure report, and even the same cell may support both TRP level beam report and cell level beam report. In this case, all cells in a cell group may only be configured with a maximum of 3 SR resources (SR resources at one cell level and SR resources at 2 TRP levels), and it is a problem how to determine suitable SR resources for failed beam reporting of each cell or TRP. If the SR resource determination is not appropriate, the terminal may send the LRR to a cell or TRP with poor link quality, reduce the transmission reliability of the LRR, and increase the delay of beam failure recovery. Especially, a cell using a cell-level BFR may have large-scale parameters such as a similar propagation environment and a spatial relationship with a certain TRP of another cell (e.g., in-band carrier aggregation (intra-band CA)), and when selecting SR resources, a cell or a TRP having similar link transmission conditions should select the same SR resources.
Therefore, the embodiments of the present application provide a resource determining method and apparatus, so as to select a more appropriate SR resource for a physical resource where a transmission failure occurs when a BFR occurs, thereby increasing transmission reliability of an LRR and reducing a time delay of beam failure recovery.

The embodiment of the present application provides a Scheduling Request (SR) resource determining scheme, which is used for a terminal to select a suitable SR resource when a physical resource (e.g., a cell or a TRansmission Point (TRP)) has a beam failure (i.e., a TRansmission failure), further to select a corresponding spatial relationship (i.e., a TRansmission filter related parameter used when an LRR is transmitted on the SR resource indicates a direction of a TRansmission beam), and to transmit the LRR (Link Recovery Request) to a cell or a TRP that has no failure, so as to increase TRansmission reliability of the LRR and reduce a delay of TRansmission failure Recovery.
Specifically, in the embodiment of the present application, the terminal determines, according to the number or the spatial relationship of the SR resources configured by the network device, and one or a combination of the following parameters, the SR resources and the spatial relationship parameters on the SR resources for the cell or the TRP where the beam failure occurs, and sends the LRR on the determined SR resources:
a BFR level of a failed cell or TRP, a number of Beam Failure Detection (BFD) Reference Signals (RSs), an association of BFD RSs to SR resources, a control resource set (CORESET, a set of physical resources, i.e., a specific area on the NR downlink resource grid) high level parameters, an association of CORESET subsets (subset) to SR resources.
In the embodiment of the present application, the beam fails, that is, the transmission fails.
Specifically, the method comprises the following steps:
the terminal determines the SR resource in the following ways:
the first method is as follows: and establishing an incidence relation between the SR resource and the BFR grade, and further establishing an incidence relation between the SR resource and a TRP index (index). And the terminal determines corresponding SR resources according to the determined BFR level. The BFR level may be a first level, a second level, or two levels, that is, a first level and a second level, configured for the BFR level in advance. The first level is for example the TRP level and the second level is for example the cell level.
Step 1: a network side configures a plurality of SR resources for a cell group in advance, wherein one part of SR resources are used for reporting BFR at a cell level, and the other part of SR resources are used for reporting BFR at a TRP level;
for example, the network device configures N (actually, it may only be applicable to the case of N = 3) SR resources (N =1,2,3, … …, etc.) for one cell group, where N1 (N1 = 1) SR resources are used for cell-level BFR reporting, and N2 (N2 = 2) SR resources are used for TRP-level BFR reporting; n = N1+ N2;
step 2: when a certain cell or TRP fails to generate beam, the terminal determines the BFR level according to the rules configured or predefined by the network equipment side:
in the configuration of the network device side, the network device side may configure, in a certain cell, a BFR of the cell level (i.e., a second-level BFR), or a BFR of the TRP level (i.e., a first-level BFR), or both of the cell and the TRP level. For example, the high-level parameter BFR _ level may be configured in a Cell configuration or a BWP (BWP-UplinkCommon or BWP-uplinkcredicted) or a BFR related configuration (BeamFailureRecoveryConfig or BeamFailureRecoveryConfig), which indicates a BFR level, and its value may be Cell _ specific, TRP _ specific, or Cell _ specific and TRP _ specific. For example, the following 2 configurations indicate that one cell (or CC) can only configure one BFR level:
BFR_level CHOICE{
Cell_specific NULL
TRP_specific NULL
}
or
BFR_level ENUMERATED{Cell_specific,TRP_specific}
For another example, the following configuration indicates that one cell (or CC) may configure one or two BFR levels:
BFR_level SEQUENCE{
Cell_specific NULL
TRP_specific NULL
}
for another example, more detailed parameters, such as the number of BFD RS sets, and BFD RSs included in each BFD RS set, may also be configured under the Cell _ specific or TRP _ specific parameter, for example:
cell _ specific SEQUENCE (SIZE (1.. 2)) OF BFD _ RS _ list, or
Cell _ specific BFD _ RS _ list, or
TRP _ specific SEQUENCE (SIZE (1.. 2)) OF BFD _ RS _ list, or TRP _ specific BFD _ RS _ list.
The BFD _ RS _ list is a high-level parameter corresponding to the BFD RS set, and may also be a high-level parameter failuredetectionresourcesttoaddmodlist or a radiolinkmentingrs in the existing protocol.
Through the explicit configuration of the network side equipment, the terminal can determine the BFR level of a certain cell. The terminal can also determine the number of BFD RS sets according to the BFR level configured by the network side equipment.
If the number of the BFD RS sets is not explicitly configured, the terminal can determine that the number of the BFD RS sets is 1 when the network side equipment configures a second-level BFR (Cell-level BFR, corresponding parameter Cell _ specific) for the terminal; when the network side device configures a first level BFR (TRP level BFR, corresponding parameter TRP _ specific) for the terminal, the number of BFD RS sets is 2. Even if the network side does not explicitly configure the BFD RS set, the terminal can determine the number of the BFD RS set according to the related configuration of the BFR level, and further determine the BFD RS. For example, the terminal determines the BFD RS contained in each BFD RS set according to the number of the BFD RS sets and/or a CORESET related high-level parameter (CORESETPoolIndex). For example, if the number of BFD RS sets is 1, the terminal determines that the BFD RS sets include a reference signal index in the TCI state of CORESET containing the PDCCH to be monitored; if the number of the BFD RS sets is 2, the terminal determines that the first BFD RS set (BFD RS set 0 or the BFD RS set with a lower index value in the cell) comprises a reference signal index in the CORESET with a CORESETPoolindex value of 0 and contains the CORESET of the PDCCH to be monitored in the TCI state; the terminal determines that the second BFD RS set (BFD RS set 1 or the BFD RS set with a higher index value in the cell) comprises a reference signal index in the TCI state of the CORESET containing the PDCCH to be monitored in the CORESET with a CORESETPoolIndex value of 1. If the PDCCH to be monitored is not contained in the CORESET with the coresetpoolndex value of 0 or 1 in a certain time slot or a certain time unit (i.e. there is no search space set to be monitored), the corresponding BFD RS set is empty, i.e. there is no corresponding BFD RS set.
If the cell and the BFR of the TRP level are configured, the terminal may further determine the BFR level of the cell at a certain failure according to predefined rules or dynamic indication on the network device side.
The predefined rule may be that a BFR level is determined according to the number of BFD RS sets, and when one BFD RS set is configured or activated for the cell, it indicates that the cell performs cell-level BFR; and when the cell is configured or activated with 2 BFD RS sets, indicating that the cell performs the BFR at the TRP level.
The BFR level is determined according to predefined rules. For example, determining the BFR level according to the number of BFD RS sets, and when one BFD RS set is configured or activated in the cell, indicating that the cell performs cell-level BFR; and when the cell is configured or activated with 2 BFD RS sets, indicating that the cell carries out the BFR at the TRP level.
Step 3: and the terminal determines the SR resources according to the determined BFR level. If the BFR level is a cell level, the terminal can directly determine the corresponding SR resource; if the BFR is at the TRP level, the terminal determines the corresponding SR resource according to the TRP index (i.e. a group of physical resource indexes, such as the index of BFD RS set or the index of New candidate beam set (NBI) set, the BFR process index, the value of control resource set index (CORESETPoolIndex), the CORESET subset index and the like). The value of coresetpoolndex may be 1 value, or 2 values, or there may be no value allocated to coresetpoolndex, that is, 0 values.
The terminal determines which SR resource should be used to transmit the LRR according to a predefined rule. The predefined rule may be at least one of:
in each cell, the value of BFD RS set, or NBI set, or BFR procedure, or CORESET subset, or coresetpoilndex with the k-th (k =0 or 1) index is associated with SR resource with k-th index among SR resources for TRP level, i.e. failure occurs, SR resource with k-th index is selected to transmit LRR.
When the BFD RS set, NBI set or BFR procedures of all cells are numbered uniformly, the SR resources may be determined according to a predefined formula, for example, a modulo result value of N2 according to an index of the BFD RS set, an index of the NBI set or an index of the BFR procedure, and the corresponding SR resources are determined.
The second method comprises the following steps: the network equipment configures the incidence relation between the SR resources and a high-level parameter list, wherein the high-level parameter list comprises a physical resource table or a BFR table (BFR _ list). The physical resource table, such as TRP table (TRP _ list) or cell or TRP set of similar spatial relationship, and the BFR table (BFR _ list) is used to represent cell or TRP set with similar BFR characteristics. And establishing the association between the TRP _ list or the BFR _ list and the SR resource.
Step 1: the network device configures N SR resources (N =1,2,3, … …, etc.) and K TRP _ list or BFR _ list for one cell group, wherein each TRP _ list or BFR _ list is associated with one SR resource.
For example, each trplist contains a set of cells or TRPs with similar TCI states or spatial relationships,
TRP_list1:CC index p,CC index q,CC index r TRP 1,CC index s TRP 1……
TRP_list2:CC index o,CC index r TRP 2,CC index s TRP 2……
each cell or index may only appear in one TRP _ list.
As another example, each BFR _ list contains a set of cells with similar TCI status or spatial relationship or a set of BFR procedures corresponding to TRPs (the BFR procedures may be global numbering within the cell group),
BFR_list1:BFR procedure a,b,c,d……
BFR_list2:BFR procedure x,y,z……
each BFR procedure may only occur in one BFR _ list.
Step 2: when the terminal detects the BFR, the TRP _ list or the BFR _ list where the cell or the TRP or the BFR process index where the wave beam fails is located is determined according to the BFR process, the BFD RS set index, the CORESET high-level parameter CORESETPoolIndex, the CORESET subset index and the like.
Step 3: the terminal determines the SR resource associated with the list according to the determined cell or the TRP or BFR process index, and sends the LRR on the determined SR resource
The third method comprises the following steps: and establishing an incidence relation between the SR resource and the BFD RS set, wherein the difference of the mode I is that the BFR level is not judged.
Step 1: the network equipment configures one associated SR resource for each BFD RS set, and the number of the associated SR resources of the BFD RS sets of all the cells in one cell group does not exceed N.
Step 2: when the terminal detects that the measured values of all the RSs in a BFD RS set are lower than a certain threshold, the terminal transmits the LRR on the SR resource associated with the BFD RS set.
The method four comprises the following steps: and establishing the correlation between the SR resource and the parameter CORESETPoolIndex or the index of the CORESET subset configured at the high layer, wherein the difference between the method I and the method II is that the BFR level is not judged.
Step 1: the network device configures N SR resources (N =1,2,3, … …, etc.) for one cell group, where SR resource i is used for a beam failure condition corresponding to CORESET group i.
Step 2: the terminal determines the related SR resource according to the CORESETPoolIndex value or the CORESET subset index of the CORESET group with beam failure, and sends LRR on the resource.
For example, the SR resource i determined by the terminal is used for a CORESET i where a transmission failure occurs; wherein the content of the first and second substances,
CORESETPoolIndex is 0 or CORESET without CORESETPoolIndex is CORESET group 0, and CORESET with CORESETPoolIndex is 1 is CORESET group 1;
or the CORESETPoolIndex value is 0 or the CORESET without the CORESETPoolIndex is 0 in the CORESET group, the CORESET with the CORESETPoolIndex value of 1 in the CORESET group 1, and the CORESETPoolIndex values of 0 and 1 in the CORESET group 2;
or the CORESET with the CORESETPoolIndex value of 0 is the CORESET group 0, the CORESET with the CORESETPoolIndex value of 1 is the CORESET group 1, and the CORESET without the CORESETPoolIndex value is the CORESET group 2;
or the CORESET with the CORESETPoolIndex value of 0 is the CORESET group 0, the CORESET with the CORESETPoolIndex value of 1 is the CORESET group 1, and the CORESET with the CORESETPoolIndex value of 2 is the CORESET group 2;
or the kth CORESET subset of the high-level parameter configuration is a CORESET group k.
Optionally, the method provided in the embodiment of the present application may further include the steps of: the terminal determines the spatial relationship of the SR resources.
Specifically, when the SR resource determined for the physical resource has a plurality of active spatial relationships, a spatial relationship associated with a physical resource index in which a transmission failure has not occurred is selected from the plurality of active spatial relationships to transmit the link recovery request LRR. The physical resource index comprises one or more of the following: an index of a beam failure detection reference signal set BFD RS set or an index of a New candidate beam set (NBI) set, a beam failure recovery BFR process index, a value of a resource set group index CORESETPoolIndex, and an index of a subset CORESET subset of a resource set.
For example, if each SR resource has 2 or more spatial relationships activated, the spatial relationship on the selected SR resource needs to be further determined.
For example, when the number of cells or TRPs selecting the same SR resource is greater than 1, the terminal determines a spatial relationship according to the TRP having a smaller cell index or TRP index among the TRPs in which the beam failure occurs, for example, selects a spatial relationship associated with the TRP in which no beam failure (non-failed) occurs (for example, 2 activated spatial relationships are respectively associated with TRP1 and TRP 2).
A description of several specific embodiments is given below.
Example 1:
multiple SR resources can be configured for the terminal, and are respectively used for BFR reporting at different levels. The method comprises the following specific steps:
step 1: the network equipment configures N SR resources (N =1,2,3, … … and the like) for a cell group, wherein N1 SR resources are used for reporting the BFR at the cell level, and N2 SR resources are used for reporting the BFR at the TRP level;
in the N SR resources configured for one cell group by the network device, which SR resource may be used for BFR reporting at the cell level or the TRP level may be configured by the network device side, or determined by the terminal according to a predefined rule.
For example, when N =3, SR resource 1 is configured for cell level BFR reporting, and SR resources 0 and 2 are configured for TRP level BFR reporting. A higher layer parameter may be included in the SR resource configuration to indicate the BFR level corresponding to the corresponding SR resource. For another example, when N =2, the network device side may configure SR resource 0 for cell-level BFR reporting, and SR resource 1 for TRP-level BFR reporting.
When N =3, it may also be determined by a predefined rule that SR resource 0 is used for cell-level BFR reporting, and SR resources 1 and 2 are used for TRP-level BFR reporting. And when N =2, determining that the SR resource 0 is used for reporting the BFR at the cell level and the SR resource 1 is used for reporting the BFR at the TRP level through a predefined rule.
For example, taking N1=1 and N2=2 as an example, as shown in fig. 1, if there are 4 cells in the Cell group, namely scells (Secondary cells) a, B, C, and D, and only scells are taken as an example for description here, one of the scells may be replaced by a PCell (Primary Cell). In fig. 1, scells a and C perform a TRP level beam failure recovery mechanism, and scells B and D perform a cell level beam failure recovery mechanism. SR resource 0 is used for cell-level beam failure recovery, and SR resources 1 and 2 are used for TRP-level beam failure recovery, which is equivalent to establishing an association relationship between SR resources and BFR levels.
Step 2: when a certain cell or TRP fails to generate a beam, the terminal determines the BFR level of the cell according to the BFR level configured on the network equipment side or according to a predefined rule.
When a beam failure occurs, the terminal may determine the BFR level according to at least one of the following methods:
the network equipment side can configure the BFR of a certain cell with the BFR level of the cell being the cell level BFR, or the BFR of the TRP level, or both the cell and the TRP level BFR. For example, the configuration may be performed in serving cell related configuration (higher layer parameter ServingCellConfig) or BWP (BandWidth Part) configuration (higher layer parameter BWP-downlink dedicated or its following higher layer parameter radiolinlummonitongconfig). If the BFRs of the cell and the TRP are configured, the terminal can further determine the BFR level of the cell when the cell fails in a certain time according to a predefined rule or a dynamic indication of a network equipment side. The predefined rule may be that the BFR level is determined according to the number of BFD RS sets, and when one BFD RS is configured or activated in the cell, it indicates that the cell performs cell-level BFR; when the cell configures or activates 2 BFD RSs, it indicates that the cell performs TRP level BFR.
The BFR level is determined according to predefined rules. For example, determining the BFR level according to the number of BFD RS sets, and when one BFD RS is configured or activated in the cell, indicating that the cell performs cell-level BFR; when the cell configures or activates 2 BFD RSs, it indicates that the cell performs TRP level BFR.
Through this step, the terminal can determine the BFR level occurring in each cell.
Step 3: and the terminal determines the SR resource according to the determined BFR level. If the BFR level is the cell level, the terminal can directly determine the corresponding SR resource; if the BFR is at the TRP level, the terminal determines the corresponding SR resource according to the TRP index (index of BFD RS set or NBI set, index of BFR process, value of CORESETPoolIndex, index of CORESET subset, etc.).
If the BFR level is a cell level, the cell only corresponds to one SR resource, namely, further selection is not needed; if the BFR level is the TRP level, it may correspond to at most 2 SR resources, and when the number of SR resources for the TRP level is 2, it is further required to determine which SR resource to use to transmit the LRR. In this embodiment, the terminal may determine, according to the TRP index (index of BFD RS set or index of NBI set, BFR procedure index, value of coresetpoolndex, index of CORESET subset, etc.), the corresponding SR resource according to at least one predefined rule as follows:
in each cell, a BFD RS set with a k-th (k =0 or 1) index, or an NBI set, or a BFR procedure, or an index of CORESET subset, or a coresetpoilndex whose value is k (k =0 or 1) is associated with an SR resource with a k-th index among SR resources for a TRP level, i.e., a failure occurs, an SR resource with a k-th index is selected to transmit an LRR. The above-mentioned k-th index refers to a k-th index determined in descending order of index values. When N =3, SR resources 1 and 2 are used for BFR reporting of the TRP level, and the kth index in the SR resources for the TRP level refers to the kth index in SR resources 1 and 2.
When indexes of the BFD RS set, NBI set, BFR procedure or CORESET subset of all cells are numbered uniformly, the SR resources may be determined according to a predefined formula, for example, when the index of the BFD RS set, the index of the NBI set, the index of the BFR procedure or the index of the CORESET subset modulo 2 is 0, the SR resource having the lowest index among the SR resources for the TRP level is selected to transmit the LRR; and when the modulus result is 1, selecting the SR resource with the highest index in the SR resources used for the TRP level to transmit the LRR. The reverse is also possible, for example, when the index of BFD RS set, NBI set, BFR procedure index, or CORESET modulo 2 is 1, the SR resource with the lowest index among SR resources for TRP level is selected to transmit LRR; and when the modulus result is 0, selecting the SR resource with the highest index in the SR resources used for the TRP level to transmit the LRR.
For example, SR resource 1 is associated with TRP index of 1 per cell (e.g., TRP1 of SCell a and SCell C), and SR resource 2 is associated with TRP index of 2 per cell (e.g., TRP2 of SCell a and SCell C). The method is suitable for the situation that the TRP1 in each cell is deployed together and the TRP2 is deployed together (and the TRP2 and the TRP1 are separated at a certain distance on the physical position). Thus, when the TRP1 of the SCell a fails, the TRP1 of the SCell C also fails with a certain probability, and the spatial relationship of the SR resources may be set to point to the direction of the TRP2 of each cell, so that when the TRP1 of the SCell a and the SCell C fails, the LRR may be sent to the TRP2 where no failure occurs, so as to increase the transmission reliability of the LRR and reduce the time delay of transmission failure recovery. The TRP2 where no failure occurs may be a TRP of a cell in which the SR resource is located. For example, in a CA (Carrier Aggregation) scenario, a PCell or a PSCell may configure an SR resource (i.e., a PUCCH), and a TRP2 may be a TRP2 of the PCell. In a DC (Dual Connectivity) scenario, the TRP2 may be TRP2 on a PCell or a PSCell (Primary SCG Cell, primary Secondary Cell Group Cell). Depending on which PUCCH the network device side configures the SR resource on.
Optionally, this embodiment may further include the following steps:
step 4: the terminal determines the spatial relationship of the selected SR resources.
If each SR resource has 2 or more active spatial relationships, the spatial relationship on the selected SR resource needs to be further determined. For example, when the number of cells or TRPs selecting the same SR resource is greater than 1, the terminal determines a spatial relationship according to the TRP having a smaller cell index or TRP index among the TRPs where failure occurs, for example, selects a spatial relationship associated with a non-failed TRP (for example, 2 activated spatial relationships are respectively associated with TRP1 and TRP 2).
The specific method may be that 2 spatial relationships on the SR resource configured on the network device side respectively correspond to TRP index 1 and TRP index 2, and the TRP index may be an index of BFD RS set or an index of NBI set, a BFR process index, a value of coresetpoolndex, an index of CORESET subset, or the like. When the terminal judges that the TRP index 1 related to the TRP generates BFR, the terminal uses the spatial relation corresponding to the TRP index 2 to send the LRR; similarly, when the terminal determines that the TRP index 2-related TRP has BFR, the spatial relationship corresponding to TRP index 1 is used to transmit LRR.
It should be noted that Step 4 is applicable to all embodiments in the present application, and the optional steps may be performed after each SR resource determination method.
Example 2:
in order to make TRP or cell select appropriate SR resource (proper spatial relation in essence) when beam failure recovery occurs, LRR can be sent to cell or TRP where no failure occurs. The network device side may also explicitly configure a higher-layer parameter TRP _ list or BFR _ list for representing cells or TRP sets with similar BFR characteristics or similar spatial relationships, and establish an association between the TRP _ list or BFR _ list and the SR resource. When the BFR occurs, the terminal may determine a list (list) where the cell or the TRP is located according to the TRP index (index of BFD RS set or index of NBI set, BFR procedure index, value of coresetpoolndex) or cell index selection that fails to send, and further select the SR resource associated with the corresponding list to send the LRR. Since the list is configured or indicated to the terminal for the network device side, the network device side can configure a suitable SR resource for the terminal according to an actual deployment situation, and ensure that the terminal sends the LRR to a cell or a TRP that has not failed.
Step 1: the network device configures N SR resources (N =1,2,3, … …, etc.) and K TRP _ list or BFR _ list for one cell group, wherein each TRP _ list or BFR _ list is associated with one SR resource.
For example, each trplist contains a set of cells or TRPs with similar TCI states or spatial relationships,
TRP _ list1: carrier unit (CC) index p, CC index q, CC index r TRP1, CC index s TRP1 … …
TRP_list2:CC index o,CC index r TRP 2,CC index s TRP 2……
Each cell or index may only appear in one TRP _ list.
As another example, each BFR _ list contains a set of cells with similar TCI status or spatial relationship or a set of BFR procedures corresponding to TRPs (the BFR procedures may be global numbering within the cell group),
BFR _ list1: BFR Process (procedure) a, b, c, d … …
BFR_list2:BFR procedure x,y,z……
Each BFR procedure may only occur in one BFR _ list.
Besides using RRC signaling configuration, TRP _ list and BFR _ list can be further activated or updated by using MAC-CE or DCI signaling to adapt to real-time change of transmission condition. For example, 2 TRPs (TPR 1 and TRP 2) are configured for a cell, and only one TRP is used for transmission (e.g., dynamic Point Selection, DPS) at a time, and a cell-level BFR is configured on TRP _ list in the form of a cell, for example, CC index k, so that the cell may appear on TRP _ list1 (i.e., CC index k appears on TRP _ list 1) when using TRP1 for communication, and may appear on TRP _ list2 (i.e., CC index k appears on TRP _ list 1) when using TRP for communication. When further activation or update is performed using media access control element (MAC-CE) or DCI signaling, it needs to be ensured that each cell or TRP can only appear on one list after update or activation, but one cell or TRP can appear on 2 lists at RRC configuration. In addition, one cell may also perform different levels of BFR at different time periods, for example, perform the cell level BFR at a certain time period, and perform the TRP level BFR at another time period, so before updating using MAC-CE or DCI signaling, indexes corresponding to the TRP level and the cell level BFR may both appear on the list, for example, CC index k appears on the list1, CC index k TRP1 appears on the list2, and CC index k TRP2 appears on the list 3. When the MAC-CE signaling or the DCI signaling is activated or updated, the MAC-CE signaling or the DCI signaling may be updated in units of list (for example, list1 is updated to list 2), or may be updated in units of a certain cell on list (for example, CC index k on list1 is updated to CC index k TRP 2).
Step 2: when the terminal detects BFR, determining the TRP _ list or BFR _ list of the failed cell or TRP or BFR process index according to the BFR process, the BFD RS set index, the CORESET high-level parameter CORESETPoolIndex, the CORESET subset index and the like.
Step 3: and the terminal determines the SR resource associated with the list according to the determined cell, the TRP or the BFR process index, and sends the LRR on the determined SR resource.
Example 3:
and an incidence relation between the SR resources and the BFD RS sets can be established, and the terminal can directly select the corresponding SR resources to transmit the LRR after detecting that a certain BFD RS set fails.
Step 1: the network equipment configures one associated SR resource for each BFD RS set, and the number of the associated SR resources of the BFD RS sets of all the cells in one cell group does not exceed N.
Specifically, in the configuration of each BFD RS set, an SR resource-related identifier is added, which may be, for example, a scheduling request identifier (scheduling request id). For example, a cell includes 4 cells, each cell has 2 BFD RS sets, 8 BFD RS sets in total, and each set has an associated schedule requestid configured therein, e.g., when N =3, the schedule requestids configured for the 2 BFD RS sets of cell 1 are 0 and 1, the 2 BFD RS sets of cell 2 are 1 and 2, the 2 BFD RS sets of cell 3 are 0 and 2, and the 2 BFD RS sets of cell 4 are 1 and 2. It can be seen that the values of the schedulingrequestids of all cell configurations are the values in the set {0,1,2 }.
For another example, when N =2, cell 1 and cell 2 each have one BFD RS set, the schedulingrequestids configured for the BFD RS sets in these 2 cells are 0 and 1, respectively, cells 3 and 4 have 2 BFD RS sets, and the schedulingrequestids configured for the 2 BFD RS sets in these 2 cells are 0 and 1, respectively. It can be seen that the values of the schedulingrequestids of all cell configurations are the values in the set {0,1 }.
In this embodiment, the index of the BFD RS set may be numbered in one cell, or may be globally numbered in one cell group, which is not limited in the present invention, and no matter what kind of numbering method is adopted, only the configuration of the SchedulingRequestId needs to be added to the configuration of the BFD RS set.
Step 2: when the terminal detects that the measurement values of all the RSs in one BFD RS set are lower than a certain threshold, the cell or TRP corresponding to the BFD RS set is considered to have beam failure, and the terminal sends the LRR on the SR resource associated with the BFD RS set.
For example, the measured values of the RSs in the 2 nd BFD RS set in cell 3 are all below the threshold, and the terminal may send the LRR to the base station on the SR resource with scheduling request id of 2.
In this embodiment, each SR resource is configured with a spatial relationship, for example, the spatial relationship of each SR resource points to one TRP or one cell, and the network device side may configure one suitable SR resource for each BFD RS set according to a deployment situation, so that the LRR may be sent to one suitable cell when a beam failure occurs. For example, when N =2, the spatial relationship of 2 SR resources (SchedulingRequestId is configured to 0 and 1) points to TRP2 and TRP1, respectively. The network device side can associate the TRP1 of the cell 1 with the SR resource 0 and associate the TRP2 with the SR resource 1, so that when the TRP1 fails, the terminal can use the SR resource 0 to send the LRR, that is, the LRR is sent to the TRP2 (i.e., there is no failed cell, the channel quality is better), which can increase the transmission reliability of the LRR and reduce the delay of the transmission failure recovery.
In particular, the present embodiment is applicable to the case where BFD RS sets are explicitly configured in the BFR procedure.
Example 4:
the association of BFD RS sets and SR resources may also be established in a predefined manner. For example, the network device side may configure N SR resources for one cell group (for example, the SchedulingRequestId value is 0,1, …, N-1), and may establish the association between the BFD RS set and the SR resources according to the following predefined rule:
when N =2, if the index of the BFD RS sets is numbered in each cell, each cell has K =2 BFD RS sets at most, and the BFD RS sets may be explicitly configured on the network device side or determined by the terminal according to a predefined rule. The terminal may determine that the BFD RS set index k (k =0 or 1) and the SR resource scheduling request id k are associated. When the terminal detects that the measured values of all RSs in the BFD RS set k are lower than the threshold, the terminal sends the LRR to the base station on the SR resource with the scheduling request Id of k. In particular, when a certain cell performs a TRP-level BFR, the number of BFD RS sets is 2 (index value is 0 or 1), and when a certain cell performs a cell-level BFR, the number of BFD RS sets is 1 (index value is 0), the above predefined rule is applicable to both the cell-level BFR and the TRP-level BFR.
If the indexes of the BFD RS set are numbered in the cell group, the association between the BFD RS set and the SR resource can be established in a modular mode. Assuming that the index value of the BFD RS set is P, when it fails, the SR resource transmitting the LRR is mod (P, N).
N =3, if the index of the BFD RS set is globally numbered within the cell group, the method is similar to that of N =2, i.e., assuming that the index value of the BFD RS set is P, when it fails, the SR resource for transmitting the LRR is mod (P, N).
If the index of the BFD RS sets is numbered in each cell, each cell has K =2 BFD RS sets at most, and the BFD RS sets may be explicitly configured on the network device side or determined by the terminal according to a predefined rule. The terminal first determines the number of BFD RS sets in the cell, and if the number is 1, associates with one SR (e.g., SR resource 0); if the number is 2, then there are 2 more SR resources associated (e.g., SR resources 1 and 2). For a cell configured with 2 BFD RS sets, it may be determined that a BFD RS set index k (k =0 or 1) and an SR resource scheduling request id n (n is 1 or 2) are associated. When the terminal detects that the measured values of all the RSs in the BFD RS set k are lower than the threshold, the terminal sends the LRR to the base station on the SR resource with the scheduling request Id being n.
In this way, the network device side can ensure that a suitable SR resource can be selected to transmit an LRR when it fails by configuring the BFD RS set index value, i.e., the spatial relationship points to the TRP or the cell that has no failure.
In particular, the present embodiment is applicable to the case of explicit configuration of BFD RS sets and implicit determination of BFD RS sets in the BFR procedure. In the implicit determination of BFD RS sets, the terminal may also determine up to 2 BFD RS sets for each cell (or BWP) according to the configuration of CORESET (explicitly configured higher layer parameter CORESET poilndex or configured CORESET subset).
Example 5:
the association between the CORESET group and the SR resource may also be established in a predefined manner, for example, the CORESET group may be an implicit packet determined according to a higher-layer parameter CORESET poialindex, or may be a CORESET subset (subset) configured on the network device side, where each CORESET subset includes one or more CORESET indexes.
Step 1: the network device configures N SR resources (N =1,2,3, … …, etc.) for one cell group, where SR resource i is used for a beam failure condition corresponding to CORESET group i.
The CORESET group is an implicit group determined according to a CORESET high-level parameter CORESETPoolIndex or a group explicitly configured by high-level signaling. For example, coresetpoindidex is 0 or CORESET without coresetpoindidex is CORESET 0, CORESET with coresetpoindidex is 1 is set 1;
or the coresetpoinidex value is 0 or a CORESET without coresetpoinidex is a CORESET group 0, a CORESET with coresetpoinidex value 1 is a group 1, and a group with coresetpoinidex values of 0 and 1 is a group 2 (for example, such configuration is suitable for CORESET configuration under the condition that the PDCCH adopts SFN (Single Frequency Network) transmission);
or the CORESET with the coresetpoinidex value of 0 is CORESET group 0, the CORESET with the coresetpoinidex value of 1 is group 1, the CORESET without the coresetpoinidex is group 2, the group numbers corresponding to the three types of CORESETs can also interact with each other, and the embodiment of the application does not limit the group numbers;
or the CORESET with coresetpoilndex 0 is CORESET 0, the CORESET with coresetpoinindex 1 is set 1, and the CORESET with coresetpoinindex 2 is set 2 (for example, this configuration is suitable for CORESET configuration when PDCCH adopts SFN transmission);
or the kth CORESET subset of the high-level parameter configuration is a CORESET group k. The network equipment configures an SR resource for each CORESET group. The number of CORESET groups is at most 3, and the number of SR resources is also at most 3.
Step 2: the terminal determines the related SR resource according to the CORESETPoolIndex value or the CORESET subset index of the CORESET group with beam failure, and sends LRR on the resource.
In particular, if there are multiple, e.g., 2, CORESET groups in which a beam failure occurs, the terminal may select SR resources corresponding to the 2 CORESET groups to transmit LRRs.
In other embodiments of the present application, if there is a BFR condition for more than one list, or there is a BFR condition for more than one TRP or cell, the terminal may send LRR on all other corresponding SR resources.
This embodiment is applicable to the case of implicit determination of BFD RS sets. When the BFD RS set is implicitly determined, the terminal can directly determine the associated CORESET group by the failed RS or the BFD RS set, and further select a proper SR resource to send the LRR.
Example 6:
SR resources can be respectively configured for each cell, each SR resource respectively corresponds to the resource for transmitting LRR when the BFR at the cell level or the BFR at the TRP level occurs, and the number of the SR resources configured for all the cells does not exceed N;
or, the SR resource of each cell represents an LRR transmission resource when the RS in the first BFD RS set fails and an LRR transmission resource when the RS in the second BFD RS set fails, respectively; when one SR resource is configured, indicating the LRR transmission resource used when the RS in the first BFD RS set fails;
or, the SR resources of each cell correspond to the first TRP index and the second TRP index, respectively. When one SR resource is configured, it is indicated for the first TRP index.
One benefit of such direct configuration of SR resources for each cell is that it can accommodate various deployments on the network equipment side. Especially a cell performing cell level BFR, which essentially can also configure multiple TRPs, selecting one TRP to work for a period of time. Thus, the network device side can configure the LRR transmission resource when the cell fails according to the deployment situation.
Similar to other embodiments, the terminal may determine that the BFD RS set or the TRP index fails, and then determine the LRR transmission resource based on the association relationship between the BFD RS set or the TRP index and the SR resource. According to the method in the embodiments 1-6, if more than one TRP or cell has transmission failure and the determined number of SR resources is more than 1, the terminal performs LRR transmission on more than one SR resource. In embodiment 7, if there is more than one TRP or cell transmission failure, the terminal first determines one cell (CC) or one TRP, and then performs LRR transmission on the SR resource corresponding to the selected cell or TRP.
Example 7:
if a beam failure or transmission failure occurs for multiple TRPs of multiple cells, for example: when the beam failure or the transmission failure occurs on the CC1 TRP2, the CC2 TRP1, and the CC3 TRP2, a default or predefined TRP index (or BFD RS set index, etc.) is determined first, and then the SR resource corresponding to the default or predefined TRP index is selected to transmit the LRR. Procedure for determining the corresponding SR resource according to the predefined TRP index refer to examples 1-6. Determining a default or predefined TRP index by one of:
firstly, selecting physical resources with beam failure through a sequence from small to large of CC indexes and then a sequence from small to large of TRP indexes, selecting TRP2 with beam failure in CC1, further selecting SR resources corresponding to TRP2 as finally determined SR resources, and carrying out LRR transmission;
and secondly, selecting physical resources with beam failure through the sequence of TRP indexes from small to large and then the sequence of CC indexes from small to large, selecting TRP1 in CC2, further selecting SR resources corresponding to TRP1 as finally determined SR resources, and carrying out LRR transmission.
And thirdly, if the TRP index has a global number, selecting one SR resource corresponding to the TRP with the largest or smallest TRP index through the TRP index as the finally determined SR resource. The global numbering refers to the uniform and continuous numbering of all TRPs (or BFD RS sets) within a cell group, for example, the TRP or BFD RS set index in CC1 is 0 and 1, the TRP or BFD RS set index in CC2 is 2, the TRP or BFD RS set index in CC3 is 3 and 4, and so on.
Optionally, the TRP index may be a BFD RS set index, a CORESET subset or group index, or a CORESET high-level parameter coresetpoilndex value, a BFR process index, or the like.
To sum up, in the embodiment of the present application, the terminal selects an appropriate SR resource for a failed cell or TRP when BFR occurs according to configuration of the network device side or according to an association relationship between a predefined SR resource and the TRP or related parameters of the cell. When the BFR occurs, the terminal may select a suitable SR resource for the failed cell or TRP to transmit the LRR, i.e., transmit the LRR to the cell or TRP that has not failed, so as to increase the transmission reliability of the LRR and reduce the delay of transmission failure recovery.
On the terminal side, referring to fig. 2, a resource determining method provided in an embodiment of the present application includes:

By the method, the terminal can determine more appropriate SR resources for the physical resources with transmission failure according to the incidence relation between the SR resources of the scheduling request and the relevant parameters of the physical resources configured or predefined by the network side. Therefore, when the BFR occurs, the terminal may select an appropriate SR resource for the failed cell or TRP (physical resource where the transmission failure occurs) to transmit the LRR, and transmit the LRR to the cell or TRP where no transmission failure occurs, so that the transmission reliability of the LRR may be increased and the delay of the transmission failure recovery may be reduced.
