Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a beam configuration for each physical cell identifier (PCI) of a set of candidate PCIs. A beam configuration for a PCI may include, for example, transmission configuration indicator (TCI) states for downlink channels and reference signals or spatial relations for uplink channels and reference signals. The UE may receive an indication of a selected subset of PCIs of the set of candidate PCIs. The UE may apply the beam configuration for each PCI of the selected subset of PCIs based on the indication of the selected subset of PCIs. The UE may then communicate according to the beam configurations for the selected subset of PCIs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may communicate in a wireless communications system. The UE may receive first control signaling indicating a first radio network temporary identifier (RNTI) and a first feedback process identifier, where the first RNTI indicates scheduling of a unicast downlink transmission. The UE may also receive second control signaling indicating a second RNTI and a second feedback process identifier, where the second RNTI indicates scheduling of a multicast downlink transmission. The UE may manage a hybrid automatic repeat request (HARM) process at the UE associated with the unicast downlink transmission and the multicast downlink transmission based on the first RNTI, the first feedback process identifier, the second RNTI, and the second feedback process identifier. The UE may also simultaneously process multicast downlink transmission and broadcast signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine a transmission beam configuration for transmitting multicast data to a user equipment (UE) in a joint transmission using a set of transmission/reception points (TRPs) based on outcomes of listen before talk (LBT) procedures performed at the TRPs. In some examples, the base station may indicate to the UE that the UE is to determine a UE beam configuration and a quasi co-location (QCL) relationship associated with the TRPs for receiving the multicast data based on signaling from the TRPs. In some examples, the base station may transmit multicast data from a first TRP (e.g., a serving cell) during a first transmission opportunity (TxOP), and the UE may determine the QCL relationship for the set of TRPs. During a second TxOP, the base station may transmit multicast data in a joint transmission from the set of TRPs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier scheduling. A base station may transmit downlink control information (DCI) messages via physical downlink control channel (PDCCH), to the UE to schedule the multiple PDSCH over multiple component carriers. The UE may monitor for the multiple PDSCH over the multiple component carriers, respectively. The UE may identify resource allocations to use for HARQ feedback transmissions associated with the multiple PDSCH, based on the DCI messages received. The DCI may include a number of control fields that the UE may use to determine resource allocations to use for the HARQ feedback transmissions. The UE may thus improve coverage for wireless communications by supporting HARQ feedback for multiple PDSCH scheduled via cross component carrier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive first downlink control information corresponding to a first group of downlink transmissions and second downlink control information corresponding to a second group of downlink transmissions. The UE may calculate a number of information bits for a feedback message including first feedback for one or more downlink transmissions of the first group and second feedback for one or more downlink transmissions of the second group. The number of information bits may include first information bits of the first feedback and second information bits of the second feedback. The UE may identify a transmission power for the feedback message based on the calculated number of information bits. The UE may transmit the feedback message including the first feedback and the second feedback using the identified transmission power.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a control resource set (CORESET) associated with decoded downlink control information (DCI) or a search space associated with the decoded DCI. The user equipment may determine a transmit receive point (TRP) differentiation between TRPs associated with a multi-TRP mode based at least in part on the CORESET associated with the decoded DCI or the search space associated with the decoded DCI. Numerous other aspects are provided.

Abstract: Since multiple transmit-receive point (TRP) communications may increase the number of physical downlink control channel (PDCCH) candidates without increasing the number of cells, new limits for multi-TRP communications may be defined. A UE may determine a PDCCH monitoring capability across all downlink serving cells that may account for multiple-TRP cells and for carrier aggregation and dual connectivity using a multiplication factor. Further, the UE may determine a limit of a number of serving cells based on the capability and a configuration of serving cells. The UE may determine a total limit of PDCCH candidates and non-overlapped control channel elements (CCEs) to monitor in a slot for a cell group and a per cell limit single TRP cells and for multiple TRP cells based on the limit of the number of serving cells. Alternatively, the limits may be defined per control resource set (CORESET) group.

Abstract: This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a multi-transmit-receive point (TRP) approach for hybrid automatic repeat request (HARQ) acknowledgment (ACK) feedback using counter downlink assignment indicators (DAIs) (cDAIs) and total DAIs (tDAIs) is provided. For example, some techniques and apparatuses described herein may provide a joint counting method in which cDAIs and tDAIs are implemented and tracked jointly between the TRPs of a multi-TRP group. This may be useful in the ideal backhaul scenario when the multi-TRP group is jointly scheduled, and may be more robust against errors than a separate counting method. Some techniques and apparatuses described herein may provide a separate counting method, in which cDAIs and tDAIs are implemented and tracked separately by the respective TRPs of a multi-TRP group.
