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.

Abstract: Aspects described herein relate to indicating downlink control information (DCI) for multicast and/or broadcast (MB) communications using DCI formats that may be based on existing DCI formats and/or size for unicast communications, paging signals, system information signals, etc., or may include shortened formats without fields for information that may not be used in MB communications.

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.
