Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a transmission type for a physical downlink shared channel, wherein the transmission type is a multicast transmission type or a unicast transmission type. The UE may determine, based at least in part on the transmission type for the physical downlink shared channel, a transmission configuration indicator state, of a plurality of possible transmission configuration indicator states, that corresponds to a quasi-co-location assumption, of a plurality of possible quasi-co-location assumptions, for the physical downlink shared channel. The UE may decode the physical downlink shared channel based at least in part on the transmission configuration indicator state. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, information that identifies an association between a first cell of a first radio access technology (RAT) and a second cell of a second RAT. The UE may perform a measurement for the first cell. The UE may determine that the measurement for the first cell satisfies a threshold value. The UE may perform an interference canceling operation for a reference signal of the second cell, or a de-weighting operation for one or more resource elements in which the reference signal interferes, based at least in part on the determination that the measurement for the first cell satisfies the threshold value and the association between the first cell and the second cell. Numerous other aspects are described.

Abstract: The base station may receive a first indication that the UE supports NR-CA with multiple PUCCH groups or NR-DC with multiple cell groups and a second indication that the UE does not support simultaneous Rx/Tx in a first frequency band and a second frequency band, and schedule communication with the UE to avoid scheduling the simultaneous Rx/Tx based on the first and second indications. The base station may avoid scheduling simultaneous Rx/Tx in a first cell group or a first PUCCH group including the first frequency band and a second cell group or a second PUCCH group including the second frequency band. The UE may skip reporting to the base station that the UE supports the NR-DC or the NR-CA with the first frequency band and the second frequency band.

Abstract: A UE may receive, from a serving cell, an activation indication for an SCell, receiving a first reference signal from the SCell, the first reference signal including at least one temporary reference signal, identify whether a second reference signal is received after processing the activation indication and before an expiration of an SCell activation time, and activate, upon identifying that the second reference signal is received, the SCell based on one or more reference signals including at least one of the first reference signal or the second reference signal. The UE may activate the SCell no later than in slot n+K, and K may be determined based on at least in part the SCell activation time.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a first common frequency resource (CFR) configured for multicast downlink communications and associated with a first bandwidth part, and an indication of a second CFR configured for broadcast downlink communications and associated with a second bandwidth part. The UE may determine whether to switch a bandwidth part for receiving downlink communications based at least in part on the indication of the first CFR and the indication of the second CFR. Numerous other aspects are provided.

Abstract: A method for wireless communication at a user equipment (UE) includes receiving, from a base station, multicast data via a multicast channel. The method also includes transmitting, to the base station, multicast feedback based on receiving the multicast data. In some examples, the multicast feedback is associated with a group of UEs including the UE. The method further includes receiving, from the base station, a re-transmission of the multicast data on the multicast channel or a unicast channel based on one or more of a number of UEs served by the base station, a number of UEs from the group of UEs providing the multicast feedback, or a radio channel condition.

Abstract: A method for wireless communication performed by a user equipment (UE) includes receiving, from a base station, a first indication to disable hybrid automatic repeat request (HARQ) feedback for a number of instances of a multicast transport block (TB). The method also includes receiving, from the base station, a second indication identifying a value of the number of instances of the multicast TB. The method further includes receiving, from the base station, one or more instances of the multicast TB. The method still further includes determining, based on the one or more received instances, whether the multicast TB is recoverable. The method further includes selectively transmitting, to the base station, HARQ feedback after all instances of the multicast TB have been transmitted by the base station based on the determination of whether the multicast TB is recoverable.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE or a component thereof configured to receive, from a base station, SPS configuration information for broadcast and/or multicast indicating a set of resources configured for feedback, with each transmit (TX) beam of a set of TX beams corresponding to a respective subset of the set of resources. The apparatus may be further configured to receive SPS signaling from the base station via one or more TX beams of the set of TX beams over each of a set of SPS occasions. The apparatus may be further configured to transmit feedback to the base station on one or more subsets of the set of resources respectively corresponding to the one or more TX beams based on the SPS signaling, the feedback indicating one of acknowledgement (ACK) or non-acknowledgement (NACK).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a single downlink control information (DCI) message that schedules communications on multiple cells, wherein the single DCI message indicates multiple time domain resource assignments (TDRAs) corresponding to the multiple cells, wherein each of the multiple TDRAs corresponds to a different scheduled communication; and communicate using the multiple TDRAs corresponding to the multiple cells, wherein the communicating comprises: transmitting the communications using the multiple TDRAs corresponding to the multiple cells, or receiving the communications using the multiple TDRAs corresponding to the multiple cells. Numerous other aspects are provided.

Abstract: Aspects of this disclosure provide methods, devices and systems for concurrently transmitting control information and data information. In some more specific aspects, a base station may transmit one or more parameters to a user equipment (UE) that indicate to the UE to refrain from transmitting uplink control information together with uplink data information in an uplink data channel. Instead, the one or more parameters may configure the UE to transmit the uplink control information and the uplink data information using overlapping resources in different channels. In some more specific aspects, the UE may transmit the uplink control information in a slot of an uplink control channel and transmit the uplink data information in a slot of the uplink data channel that at least partially overlaps with the slot of the uplink control channel.
