When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity. ## Claims ### Claim 1 A method for operating a wireless user equipment (UE), the method comprising: receiving configuration information comprising a first value, comprising a 1 or a 0, of a pool index for a first control resource set (CORESET), wherein the pool index is configured to be either 1 or 0, wherein respective values of the pool index have one to one associations with respective transmission and reception points (TRPs); receiving a plurality of Physical Downlink Control Channel (PDCCH) transmissions scheduling a plurality Physical Downlink Shared Channel (PDSCH) transmissions; transmitting, in response to a first PDSCH transmission, a first report of control information including a hybrid automatic request (HARQ) acknowledgement or negative acknowledge in a first Physical Uplink Control Channel (PUCCH) transmission, wherein the first report of control information: is associated with the first value of the pool index corresponding to the first CORESET when a first PDCCH transmission scheduling the first PDSCH is received on the first CORESET; or is associated with a second value of the pool index corresponding to a second CORESET when the first PDCCH transmission scheduling the first PDSCH is received on the second CORESET, wherein the pool index is not configured for the second CORESET. ### Claim 2 (depends on 1) The method of claim 1, wherein the configuration information directs the UE to configure a pool index value for a particular PUCCH resource. ### Claim 3 (depends on 1) The method of claim 1, wherein the configuration information includes spatial relation information. ### Claim 4 (depends on 1) The method of claim 1, wherein the configuration information directs the UE to configure a pool index value for a particular PUCCH resource group. ### Claim 5 (depends on 1) The method of claim 1, wherein the first PDCCH also schedules the first report of control information in the first PUCCH transmission. ### Claim 6 (depends on 5) The method of claim 5, wherein the first value is used to select appropriate control information to include in the first PUCCH transmission. ### Claim 7 (depends on 1) The method of claim 1, further comprising receiving a downlink message that configures resources for transmission of a semi-persistent type or a periodic type of control information in the PUCCH. ### Claim 8 (depends on 1) The method of claim 1, further comprising selecting a selected CORESET from a plurality of configured CORESETs, wherein the selected CORESET is the CORESET having a highest or lowest CORESET ID among said configured CORESETs. ### Claim 9 (depends on 1) The method of claim 1, further comprising selecting a selected CORESET from a plurality of configured CORESETs, wherein the selected CORESET is a CORESET that has been indicated by higher layer signaling. ### Claim 10 (depends on 1) The method of claim 1, further comprising selecting a selected CORESET from a plurality of configured CORESETs, wherein the selected CORESET is a CORESET with lowest CORESET ID among monitored CORESETs from a last slot before a present PUCCH opportunity. ### Claim 11 (depends on 1) The method of claim 1, further comprising selecting a selected CORESET from a plurality of configured CORESETs, wherein the PUCCH is activated in response to receiving the configuration information. ### Claim 12 An apparatus, comprising: a processor configured to cause a user equipment (UE) to perform operations including: receiving configuration information comprising a first value, comprising a 1 or a 0, of a pool index for a first control resource set (CORESET), wherein the pool index is configured to be either 1 or 0, wherein respective values of the pool index have one to one associations with respective transmission and reception points (TRPs);
