There are multiple reporting modes for CSI, and reporting Semi-Persistent (SP) CSI through a Physical Uplink Shared Channel (PUSCH) as one of the CSI reporting modes may be triggered by Downlink Control Information (DCI). In a transmission scene of a multi transmission and reception point (multi-TRP), transmitting SP-CSIreport on a PUSCH through DCI trigger, wherein one semi-persistent CSI trigger in the PUSCH corresponds to one report ID reported on the PUSCH. Transmission of multi-TRP can be classified into transmission based on multi-DCI (multi-DCI based) and transmission based on single-DCI (single-DCI based).
For a multi-DCIbased transmission service scenario, two base stations do not interact with each other in time and respectively send DCI to a user terminal, and the user terminal can distinguish which TRP the received DCI belongs to according to a related high-level parameter in a Control resource set (CORESET) related to each DCI.

In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a flowchart of a semi-persistent scheduling method in multi-transmission receiving point transmission in the embodiment of the present invention is shown, and the method is used for a base station, and specifically includes the following steps:
and step 11, generating a target RRC signaling in the service based on single DCI transmission and sending out the target RRC signaling.
In specific implementation, the base station may determine the current service type according to the information interaction condition of each base station within the interaction delay range. In multi-transmission reception point (multi-TRP) transmission, if the current service of a base station is based on single-DCI (DCI based) transmission, a target Radio Resource Control (RRC) signaling is generated and sent out.
In a multi-TRP transmission scene, in single-DCI based transmission, information can be interacted between two or more TRPs in time, so that the DCI can be sent through one TRP, and the DCI at the moment contains control information which needs to be issued by the two or more TRPs.
In a specific implementation, the target RRC signaling includes CSI report configuration information. The CSI report configuration information may include arrangement positions corresponding to a plurality of semi-persistent CSI trigger states and a plurality of semi-persistent CSI trigger states, respectively.
In particular implementations, the plurality of semi-persistent CSI trigger states may correspond to a plurality of different deployment locations. For example, one permutation position corresponds to one semi-persistent CSI trigger state, each semi-persistent CSI trigger state indicating one or more semi-persistent CSI reports. As another example, one arrangement location corresponds to multiple semi-persistent CSI trigger states, each indicating one semi-persistent CSI report.
In the embodiment of the invention, the CSI report configuration information in the target RRC signaling is carried in a list mode. For example [ CSI-semi PersistentOnPUSHTrigRegState _0; CSI-semiPersistentOnPUSHTriggerState _1; CSI-semiPersistentOnPUSHTrigge rState _2; CSI-semiPersistentOnPUSHTriggerState _3; CSI-semi PersistentOnPUSC HTriggERState _4]. The CSI report configuration information includes 5 semi-persistent CSI trigger states, in punctuation; the boundary is used for distinguishing arrangement positions where the semi-persistent CSI trigger states are located, and one semi-persistent CSI trigger state is located at each arrangement position. As another example, [ CSI-semipersistent on puschhtriggerstate _0; CSI-semiPersistentOnPUSHTriggerState _1, CSI-semiPersistentOnPUSHTriggerState _2; CSI-semiPersistentOnPUS CHTriggerState _2, CSI-semiPersistentOnPUSHTriggerState _4; CSI-semi persistent tOnPUSHTriggerState _3; CSI-semi PersistentOnPUSHTriggerState _4]. The first configuration position is CSI-semi persistent ON PUSCHTRIGGERSTATE _0, the second configuration position is CSI-semi persistent ON PUSCHTRIGGERSTATE _1 and CSI-semi persistent ON PUSCHTRIGGERSTATE _2, and the third configuration position is CSI-semi persistent ON PUSCHTRIGGERSTATE _2 and CSI-semi persistent ON PUSCHTRIGGERSTATE _4.
In particular implementations, the target RRC signaling may be generated in a variety of ways, as illustrated below.
In an embodiment of the present invention, the target RRC signaling is configured in the following manner: and the original RRC signaling output by the RRC layer is configured and adjusted through the MAC layer to obtain the target RRC signaling. In the CSI report configuration information of the original RRC signaling, each configuration position corresponds to one semi-continuous CSI trigger state one by one, each semi-continuous CSI trigger state corresponds to one CSI report configuration identifier one by one, and one CSI report configuration identifier indicates one semi-continuous CSI report. In the CSI report configuration information of the target RRC signaling, at least one configuration position corresponds to a plurality of semi-continuous CSI trigger states, and each semi-continuous CSI trigger state corresponds to one CSI report configuration identifier one by one.
In a specific implementation, the RRC layer may configure a semi-persistent CSI trigger state list (CSI-semi persistent on PUSCH-triggerstatlist) on one PUSCH, and configure at most 64 semi-persistent CSI trigger states (CSI-semi persistent on PUSCH-triggerstatlist) on one PUSCH.
The CSI report configuration information of the original RRC signaling output by the RRC layer adopts a mode of a list CSI-semipersistent OnPUSCH-TriggerStateList, and the configuration position of the semi-persistent CSI trigger state refers to the position of each row of the CSI-semipersistent OnPUSCHTriggerState in the list. The CSI-semipersistent OnPUSCH-TriggerStateList comprises 8 CSI-semipersistent OnPUSCH-TriggerStaterespectively, the CSI-semipersistent OnPUSCH-TriggerStaterespectively corresponds to 8 configuration positions, each configuration position corresponds to one CSI-semipersistent OnPUSCH-TriggerStaterespectively, each CSI-semipersistent OnPUSCH-TriggerStatecorresponds to one CSI-reportConfigId one by one, namely the CSI-reportConfigId corresponds to 8 CSI-reportConfigIds in total.
For example, the CSI report configuration information in the original RRC signaling output by the RRC layer is as follows: the CSI-semiPersistentOnPUSHTriggerStatList includes [ CSI-semiPersistentOnPUSHTriggerState _0; CSI-semiPersistentOnPUSHTriggerState _1; CSI-semiPersistentOnPUSHTriggerState _2; CSI-semiPersistentOnPUS CHTriggerState _3; CSI-semiPersistentOnPUSHTriggerState _4; CSI-semi persistent tOnPUSHTriggerState _5; CSI-semiPersistentOnPUSHTriggerState _6; CSI-semiPersistentOnPUSHTriggerState _7]. The corresponding relationship between CSI-semipersistent ONPUSCHTRIGGERSTATE and CSI-reportConfigId is as follows: CSI-semiPersistentOnPUSHTriggerState _0 corresponds to CSI-reportConfigId _0; the CSI-semipersistent ONPUSCHTRIGGERSTATE _1 corresponds to CSI-reportConfigId _1; the CSI-semipersistent ONPUSCHTRIGGERSTATE _2 corresponds to CSI-reportConfigId _2; the CSI-semiPersistentOnPUSHTriggerState _3 corresponds to CSI-reportConfigId _3; the CSI-semiPersistentOnPUSHTriggerState _4 corresponds to CSI-reportConfigId _4; the CSI-semiPersistentOnPUSHTriggerState _5 corresponds to CSI-reportConfigId _5; the CSI-semipersistent ONPUSCHTRIGGERSTATE _6 corresponds to CSI-reportConfigId _6; CSI-semiPersistentOnPUSHTriggerState _7 corresponds to CSI-reportConfigId _7. The fourth configuration position is SI-semiPersistentOnPUSHTriggerState _3, and CSI-semiPersistentOnPUSHTriggerState _3 corresponds to CSI-reportConfigId _3.
The original RRC signaling is input to an MAC layer, and the CSI report configuration information in the original RRC signaling is configured and adjusted through an MAC CE, so that one configuration position can correspond to a plurality of CSI-semipersistent ONPUSCHRterTiggerState, and each CSI-semipersistent ONPUSCHRtRgState corresponds to one CSI-reportConfigId.
For example, the CSI report configuration information in the target RRC signaling is as follows: the CSI-semiPersistentOnPUSHTriggerStatList includes [ CSI-semiPersistentOnPUSHTriggerState _0; CSI-semiPersistentOnPUSHTriggerState _1, CSI-semiPersistentOnPUSHTriggerState _2; CSI-semiPersistentOnPUS CHTriggerState _2; CSI-semiPersistentOnPUSHTriggerState _3, CSI-semiPersistentOnPUSHTriggerState _5; CSI-semiPersistentOnPUSHTriggerState _4; CSI-semiPersistentOnPUSHTriggerState _5; CSI-semi PersistentOnPUSHTrigger rState _6, CSI-semi PersistentOnPUSHTrigger rState _0; CSI-semiPersistentOnPUSC HTrigger State _7]. The correspondence between the CSI-semipersistent on puschhtriggerstate and the CSI-reportConfigId is as follows: CSI-semiPersistentOnPUSHTriggerState _0 corresponds to CSI-reportConfigId _0; the CSI-semiPersistentOnPUSHTriggerState _1 corresponds to CSI-reportConfigId _1; the CSI-semiPersistentOnPUSHTriggerState _2 corresponds to CSI-reportConfigId _2; the CSI-semipersistent ONPUSCHTRIGGERSTATE _3 corresponds to CSI-reportConfigId _3; the CSI-semiPersistentOnPUSHTriggerState _4 corresponds to CSI-reportConfigId _4; the CSI-semiPersistentOnPUSHTriggerState _5 corresponds to CSI-reportConfigId _5; the CSI-semipersistent ONPUSCHTRIGGERSTATE _6 corresponds to CSI-reportConfigId _6; CSI-semiPersistentOnPUSHTriggerState _7 corresponds to CSI-reportConfigId _7. After the configuration adjustment is performed by the MAC CE, CSI-semipersistent on puschtriggerstate _3 and CSI-semipersistent on puschtriggerstate _5 are located at the fourth configuration position, and since CSI-semipersistent on puschtriggerstate _3 corresponds to CSI-reportConfigId _3 and CSI-semipersistent on puschtriggerstate _5 corresponds to CSI-reportConfigId _5, all the half-holding CSI triggered states CSI-semipersistent on puschriggerstate _3 and CSI-semipersistent on puschriggerstate _5 at one configuration position may correspond to SP-CSI-reportof two TRPs.
It can be understood that the number of CSI-semipersistent on puschtriggerstate included in CSI-semipersistent on pusch-triggerstatestlist is not limited to 8 in the above example, and may be other numbers, the number of CSI-semipersistent on puschtriggerstate corresponding to one arrangement position is not limited to 2, and may be 1, 3 or other numbers, and the base station may be set according to the requirement actually used in the scene.
In another embodiment of the present invention, the target RRC configuration signaling is obtained as follows: and configuring and generating target RRC signaling in an RRC layer. In the CSI report configuration information of the target RRC signaling, each configuration position corresponds to one semi-continuous CSI trigger state, at least one semi-continuous CSI trigger state corresponds to a plurality of CSI report configuration identifications, and one CSI report configuration identification indicates one semi-continuous CSI report.

For example, the CSI report configuration information in the target RRC signaling is as follows: the CSI-semiPersistentOnPUSHTriggerStatList includes [ CSI-semiPersistentOnPUSHTriggerState _0; CSI-semiPersistentOnPUSHTriggerState _1; CSI-semiPersistentOnPUSHTrigge rState _2; CSI-semiPersistentOnPUSHTriggerState _3; CSI-semi PersistentOnPUSC HTriggerState _4; CSI-semiPersistentOnPUSHTriggerState _5; CSI-semiPersistentOnPUSHTriggerState _6; CSI-semi PersistentOnPUSHTrigger rState _7]. The corresponding relationship between CSI-semipersistent ONPUSCHTRIGGERSTATE and CSI-reportConfigId is as follows: CSI-semiPersistentOnPUSHTriggerState _0 corresponds to CSI-reportConfigId _0, CSI-reportConfigId _2; the CSI-semiPersistentOnPUSHTrigger State _1 corresponds to CSI-reportConfigId _1 and CSI-reportConfigId _4; CSI-semiPersistentOnPUSHTriggerState _2 corresponds to CSI-reportConfigId _2 and CSI-reportConfigId _3; the CSI-semiPersistentOnPUSHTrigger State _3 corresponds to CSI-reportConfigId _3; CSI-semiPersistentOnPUSHTriggerState _4 corresponds to CSI-reportConfigId _4 and CSI-reportConfigId _2; CSI-semiPersistentOnPUSHTriggerState _5 corresponds to CSI-reportConfigId _7 and CSI-reportConfigId _6; the CSI-semiPersistentOnPUSHTriggerState _6 corresponds to CSI-reportConfigId _6; CSI-semiPersistentOnPUSHTriggerState _7 corresponds to CSI-reportConfigId _7 and CSI-reportConfigId _1. The fourth configuration position corresponds to CSI-semiPersistentOnPUSHTriggerState _3, and CSI-semiPersistentOnPUSHTriggerState _3 corresponds to CSI-reportConfigId _3. As another example, the sixth configuration position corresponds to CSI-semiPersistentOnPUSHTriggerState _5, and CSI-semiPersistentOnPUSHTriggerState _5 corresponds to CSI-reportConfigId _7 and CSI-reportConfigId _6.

In specific implementation, the DCI includes a CSI request (request) field codeword, where the CSI request field codeword is used to indicate a target configuration location, and the target configuration location corresponds to a target semi-persistent CSI trigger state in CSI report configuration information. The target semi-persistent CSI trigger state corresponds to a plurality of semi-persistent CSI reports. The target semi-persistent CSI trigger state is included in the plurality of semi-persistent CSI trigger states, that is, the target semi-persistent CSI trigger state may be one of the plurality of semi-persistent CSI trigger states, two of the plurality of semi-persistent CSI trigger states, or another number.
After receiving the target RRC signaling and the DCI, the UE may obtain, according to a CSI request field codeword in the DCI, a target configuration position indicated by the CSI request field codeword from CSI report configuration information in the RRC signaling, obtain a target semi-persistent CSI trigger state of the target configuration position in the CSI report configuration information, obtain a plurality of semi-persistent CSI trigger reports corresponding to the target semi-persistent CSI trigger state, and report a plurality of semi-persistent CSI reports corresponding to the target semi-persistent CSI trigger state on the PUSCH.
For example, the CSI request domain codeword received by the UE is 011, the target semi-persistent CSI trigger states corresponding to the fourth arrangement position in the CSI report configuration information are CSI-semipersistent on puschtriggerstate _3 and CSI-semipersistent on puschtriggerstate _5 when the CSI request domain codeword in the DCI is 011, thereby implementing that one DCI activates two semipersistent on puschriggerstaterstate, CSI-semipersistent on puschhtriggerstate _3 and CSI-semipersistent puschriggerstate _5, and implementing that one CSI request domain codeword of one DCI corresponds to two semipersistent puschriggerstate, and one CSI request domain codeword corresponds to trpsp-CSI-report of two DCI.
For another example, when the CSI request domain codeword received by the UE is 101, the CSI request domain codeword corresponding to 101 at this time is in a sixth target semi-persistent CSI triggered state CSI-semipersistent on transmit state _5, and the CSI-semipersistent on transmit state _5 corresponds to two CSI-reportconfigs (CSI-reportConfigId _7 and CSI-reportConfigId _ 6), at this time, it may be implemented that the CSI request domain codeword of one DCI triggers SP-CSI-ports of two TRPs.
As can be seen from the above, in the single-DCI transmission-based service of the semi-persistent scheduling transmitted by multiple transmission/reception points, the generated target RRC signaling includes CSI report configuration information, where the CSI report configuration information includes multiple semi-persistent CSI trigger states and arrangement positions corresponding to the multiple semi-persistent CSI trigger states, and a CSI request field codeword included in the generated DCI is used to indicate a target arrangement position, where the target arrangement position corresponds to the target semi-persistent CSI trigger state in the CSI report configuration information, the target semi-persistent CSI trigger state is included in the multiple semi-persistent CSI trigger states, and the target semi-persistent CSI trigger state corresponds to the multiple semi-persistent CSI reports, so that the user terminal reports the multiple semi-persistent CSI reports on one PUSCH according to the received DCI.
The embodiment of the invention also provides a semi-persistent scheduling method in the transmission of the multi-sending receiving point, which is used for the UE. Referring to fig. 2, a flowchart of another semi-persistent scheduling method in multi-transmission receiving point transmission in the embodiment of the present invention may specifically include the following steps:
step 21, receiving target RRC signaling and DCI.
In specific implementation, the received target RRC signaling includes CSI report configuration information, where the CSI report configuration information includes configuration positions corresponding to a plurality of semi-persistent CSI trigger states and a plurality of semi-persistent CSI trigger states, respectively.
In an embodiment of the present invention, at least one of the arrangement locations corresponds to a plurality of semi-persistent CSI trigger states, and each of the semi-persistent CSI trigger states corresponds to one semi-persistent CSI trigger report, so that the plurality of semi-persistent CSI trigger states at one arrangement location correspond to a plurality of semi-persistent CSI trigger reports in total. The CSI-semipersistent on puschriggerstatelist in the CSI report configuration information includes 8 CSI-semipersistent on puschriggerstates, which are CSI-semipersistent on puschriggerstate _0 to CSI-semipersistent on puschriggerstate _7, respectively, and there are 8 CSI-reportconfigids, which are CSI-reportConfigId _0 to CSI-reportConfigId _7, respectively, and each CSI-semipersistent on puschriggerstate corresponds to one CSI-reportConfigId.
In another embodiment of the present invention, one semi-persistent CSI trigger state corresponds to one configuration location, and one semi-persistent CSI trigger state may correspond to a plurality of semi-persistent CSI trigger reports. For example, the CSI report configuration information of the target RRC signaling adopts a list CSI-semipersistent onpusch-TriggerStateList manner. The CSI-semi persistent on PUSCHRIGGERStatList includes 8 CSI-semi persistent on PUSCHRIGGERSTATes, which are respectively CSI-semi persistent on PUSCHRIGGERSTATe _0 to CSI-semi persistent on PUSCHRIGGERSTATe _7,8 CSI-semi persistent on PUSCHRIGGERSTATes sequentially corresponding to 8 arrangement positions, and each CSI-semi persistent on PUSCHRIGGERSTATe corresponds to one or two CSI-reportConfigIDs.
In a specific implementation, the DCI includes a CSI request field codeword, where the CSI request field codeword is used to indicate a target semi-persistent CSI trigger state at a target arrangement position, the target semi-persistent CSI trigger state is included in a plurality of semi-persistent CSI trigger states, and the target semi-persistent CSI trigger state corresponds to a plurality of semi-persistent CSI reports. All the semi-persistent CSI trigger states at the target deployment location are target semi-persistent CSI trigger states, so that the target semi-persistent CSI trigger states may include one semi-persistent CSI trigger state, or 2 or other numbers of semi-persistent CSI trigger states.
For example, a CSI request field codeword of 000 is used to indicate a target semi-persistent CSI trigger state CSI-semi persistent on puschhtrigggerstate _0 at a first deployment location. The CSI request field codeword is 001 for indicating a target semi-persistent CSI trigger state CSI-semipersistent onwishtriggerstate _1 and CSI-semipersistent onwishtriggerstate _2 at the first deployment location. The CSI request field codeword of 011 is used to indicate a first configuration position, and the target configuration positions correspond to target semi-persistent CSI trigger states CSI-semi persistent on puschhtriggerstate _3 and CSI-semi persistent on puschhtriggerstate _5 in the CSI report configuration information.
As another example, a CSI request field codeword of 000 is used to indicate a first arrangement location corresponding to a target semi-persistent CSI trigger state CSI-semi persistent on puschhtriggerstate _0. The CSI request field codeword of 001 is used to indicate a second configuration position, and the second configuration position corresponds to the target semi-persistent CSI trigger state CSI-semi persistent on transmit state _1. The CSI request field codeword of 010 is used to indicate a third configuration position, and the third configuration position corresponds to the target semi-persistent CSI trigger state CSI-semi persistent on puschhtriggerstate _2. The CSI request field codeword of 011 is used to indicate a fourth arrangement position, which corresponds to the target semi-persistent CSI trigger state CSI-semi persistent on puschhtriggerstate _3. The CSI request field codeword of 100 is used to indicate a fifth configuration position, where the fifth configuration position corresponds to the target semi-persistent CSI trigger state CSI-semi persistent on transmit state _4. The CSI request field codeword of 101 is used to indicate a sixth configuration position, where the sixth configuration position corresponds to the target semi-persistent CSI trigger state CSI-semi persistent on puschhtriggtstate _5. The CSI request field codeword of 110 is used to indicate a seventh configuration position, which corresponds to the target semi-persistent CSI trigger state CSI-semi persistent on puschhtriggerstate _6. The CSI request field codeword of 111 is used to indicate an eighth configuration position, where the eighth configuration position corresponds to the target semi-persistent CSI trigger state CSI-semi persistent on puschhtriggerstate _7.
And step 22, judging whether the current service is based on single DCI transmission according to the DCI and is in a semi-persistent scheduling activation state.
In a specific implementation, whether the service is based on single DCI transmission may be determined according to the DCI. In addition, if the CRC scrambling of the DCI is SP-CSI-RNTI scrambling, and a codeword corresponding to an automatic retransmission process number (HARQ process number) field in the DCI is 0000 and a codeword corresponding to a Redundancy version (Redundancy version) field is 00, it is determined to be in the semi-persistent scheduling active state.
For example, if the UE receives the DCI0_1 scrambled by the SP-CSI-RNTI, the codeword corresponding to the CSI request field is 101, and the codeword corresponding to the HARQ process number field is 0000, and the codeword corresponding to the Redundancy version field is 00, it is determined that the UE is in the semi-persistent scheduling active state.
Step 23, if the current service is based on single DCI transmission and is in a semi-persistent scheduling activation state, acquiring the target semi-persistent CSI trigger state corresponding to the CSI request field code word according to the CSI request field code word in the DCI and the CSI report configuration information in the target RRC signaling.
For example, the UE receives DCI0_1 scrambled by SP-CSI-RNTI, and the CSI request field codeword is 011, and at this time, the codeword corresponding to the HARQ process number field is 0000, and the codeword corresponding to the Redundancy version field is 00, the UE is in the half-scheduling activation state, and may acquire, according to the CSI report configuration information in the target RRC signaling, that CSI request field codeword 011 corresponds to CSI-semipersistent on puschrigger state _3 and CSI-semipersistent on puschrigger state _5, that is, the DCI activates two semipersistent on puschrigger states, CSI-semipersistent on puschrigger state _3 corresponds to CSI-persistent _3, CSI-semipersistent puschrigger state _5 corresponds to CSI-persistent _5, thereby implementing one CSI-CSI request field codeword corresponding to two CSI-id codes of the DCI.
And 24, reporting a plurality of semi-continuous CSI reports corresponding to the target semi-continuous CSI trigger state on a PUSCH.
As can be seen from the above, since the CSI request domain codeword in the DCI indicates the target configuration location, the target configuration location corresponds to the target semi-persistent CSI trigger state in the CSI report configuration information, and the target semi-persistent CSI trigger state may correspond to multiple semi-persistent CSI reports, it is possible to implement reporting of multiple semi-persistent CSI reports on the PUSCH by using one DCI trigger when transmitting based on a single DCI.
In practical application, when the transmission is switched from the multi-sending receiving point to the single-sending receiving point, one semi-persistent CSI report is selected from a plurality of semi-persistent CSI reports corresponding to a target semi-persistent CSI trigger state and reported.
In specific implementation, each semi-persistent CSI report has a CSI report configuration identifier corresponding to one-to-one, and one of the semi-persistent CSI reports can be selected from a plurality of semi-persistent CSI reports corresponding to a target semi-persistent CSI trigger state in a plurality of ways and reported.
In an embodiment of the invention, the CSI reporting configuration of the plurality of semi-persistent CSI reports is selected to identify the first ranked semi-persistent CSI report. For example, the target semi-persistent CSI trigger state corresponds to CSI-reportConfigId _7 and CSI-reportConfigId _6, selecting CSI-reportConfigId _7 ranked on the first bit.
In another embodiment of the present invention, the CSI reporting configuration of the plurality of semi-persistent CSI reports is selected to identify the smallest semi-persistent CSI report. For example, the target semi-persistent CSI trigger state corresponds to CSI-reportConfigId _7 and CSI-reportConfigId _6, and the CSI-reportConfigId _6 with the smaller CSI-reportConfigId is selected.
It may be understood that a semi-persistent CSI report with a largest CSI report configuration identifier in the plurality of semi-persistent CSI reports may also be selected, and one of the semi-persistent CSI reports may also be selected from the plurality of semi-persistent CSI reports corresponding to the standard semi-persistent CSI trigger state in another manner, which is not illustrated here.
The embodiment of the invention also provides a semi-persistent scheduling method in the transmission of the multi-sending receiving point, which is used for the UE. Referring to fig. 3, a flowchart of a method for semi-persistent scheduling in multi-transmission/reception point transmission in an embodiment of the present invention is shown, which may include the following steps:
and step 31, judging whether the current service is based on multi-DCI transmission according to the received DCIs.
In a specific implementation, the UE may distinguish which TRP the DCI received at this time belongs to according to the associated higher layer parameter in the control resource set (CORESET) associated with each DCI, so as to determine whether the traffic is based on multi-DCI transmission. For example, when the control resource set pool indexes (coresetpoolndex) are different, it may be determined that the DCI is from different TRPs, i.e., traffic transmitted for multiple DCIs.
Step 32, if the current service is a service transmitted based on a plurality of DCIs and the CSI request fields in the DCIs are the same, the UE does not perform the semi-persistent scheduling processing, or selects one of the DCIs as a target DCI, and reports a semi-persistent CSI report corresponding to the semi-persistent CSI trigger state indicated by the target DCI.
In specific implementation, for multi-DCI based transmission, when CSI request domain codewords in two DCIs are the same, the same CSI-reportConfig corresponds to a joint CSI report, and the UE may consider an error scene and does not perform semi-persistent scheduling processing. The UE can also select one of the DCIs as a target DCI, perform semi-persistent scheduling based on the target DCI, and report a semi-persistent CSI report corresponding to the semi-persistent CSI trigger state indicated by the target DCI. By making explicit the semi-persistent scheduling behavior of the UE, only one DCI is selected as the target DCI, and the semi-persistent scheduling processing is performed based on the target DCI, so that repeated calculation is not needed, and the CPU overhead can be saved.
In a specific implementation, a plurality of DCI-associated control resource sets (CORESET) respectively correspond to different control resource set identifiers (CORESET ids), and at least two different CORESET pool indexes (CORESET pool indexes) are different.
For example, the UE receives DCI _0 and DCI _1 transmitted by two TRPs, where the CORESET associated with the two DCIs corresponds to different CORESET ids respectively, and the different CORESET corresponds to different CORESET poilndex. DCI _0 corresponds to CORESETID _2, coresetpoilndex =1.DCI _1 corresponds to coreset id _4, coreset poilndex =0.
In a specific implementation, one of the DCIs may be selected as a target DCI in a variety of ways.
In an embodiment of the present invention, a target DCI is selected from a plurality of DCIs according to control resource set identifiers corresponding to control resource sets associated with the plurality of DCIs, respectively.
For example, DCI _0 corresponds to CORESETID _2, coresetpoilndex =1.DCI _1 corresponds to coreset id _4, coreset poilndex =0. And the UE selects DCI _0 corresponding to CORESET with smaller default CORESETID, discards DCI _1 and takes DCI _0 as target DCI. At this time, the UE does not process the DCI _1 to avoid repeated calculation and reduce resource occupation.
For another example, the UE selects DCI _1 corresponding to CORESET with a larger CORESET id, discards DCI _0, and takes DCI _1 as the target DCI.
In another embodiment of the present invention, a target DCI is selected from a plurality of DCIs according to a control resource set pool index corresponding to a control resource set associated with the plurality of DCIs.
For example, the UE selects DCI corresponding to the default coresetpoilndex =0, that is, DCI _1 is used as the target DCI, and DCI _0 is discarded.
For another example, the UE selects the DCI corresponding to coresetpoilndex =1, that is, DCI _0 is used as the target DCI, and DCI _1 is discarded.
As can be seen from the above, in the transmission of multi-DCI based, when two DCIs trigger the same CSI report (joint reporting), the processing behavior of the terminal is determined by not performing semi-persistent scheduling processing or selecting one from the multiple DCIs as a target DCI, and reporting a semi-persistent CSI report corresponding to a semi-persistent CSI trigger state indicated by the target DCI, so as to save the CPU overhead.
