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: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may support two or more uplink switching periods for transmit chain switching. The UE may transmit a UE capability message indicating the UE capability to support a first uplink switching period and a second uplink switching period for transmit chain switching. The first uplink switching period and the second uplink switching period may each correspond to different switching periods associated with configuration switches between different transmit chain configurations of the UE. The UE and a base station may select an uplink switching period from among the first uplink switching period and the second uplink switching period. The UE may transmit an uplink data message to the base station after a preparation time that is based on the uplink switching period.

Abstract: Aspects relate to power headroom reporting for carriers unconfigured for uplink communication are described. In some aspects, a user equipment (UE) may transmit, to a network entity, a power headroom report (PHR) including first power headroom information for a configured carrier configured for uplink communication and second power headroom information for at least one unconfigured carrier that is unconfigured for uplink communication. The UE may further receive, from the network entity, a message indicating a selected carrier comprising one of the configured carrier and the at least one unconfigured carrier in response to the PHR, and may transmit, to the network entity, an uplink transmission via the selected carrier. Other aspects, embodiments, and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, a multi-cell downlink control information (MC-DCI) that indicates scheduling information for co-scheduled component carriers (CCs), wherein the MC-DCI indicates one or more of an antenna port(s) field or a modulation and coding scheme (MCS) field to be commonly applied to one or more of the co-scheduled CCs. The UE may perform a transmission based at least in part on the scheduling information indicated by the MC-DCI. Numerous other aspects are described.

Abstract: Aspects of the disclosure provide techniques and apparatuses for improving reception of concurrent transmissions from different network entities. A user equipment may receive a first instance of a transmission in a first component carrier from a first network entity and also receive a second instance of the transmission in a second component carrier from a second network entity. The UE may then dynamically adjust a number of receivers used for the reception of the first component carrier and the reception of the second component carrier based on whether a receive time difference, between receipt of the first instance of the transmission and receipt of the second instance of the transmission, exceeds a maximum receive time difference (e.g., a cyclic prefix duration of the transmission).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more physical downlink shared channel (PDSCH) communications scheduled by downlink control information (DCI). The UE may transmit, for the one or more PDSCH communications, hybrid automatic repeat request (HARQ) feedback using a sub-codebook of a set of sub-codebooks, wherein the sub-codebook is a single-cell scheduling sub-codebook, of the set of sub-codebooks, or a multi-cell scheduling sub-codebook, of the set of sub-codebooks, based at least in part on whether the DCI is a first format configured for scheduling on a single carrier or a second format configured for scheduling on a plurality of carriers. Numerous other aspects are described.

Abstract: Aspects described herein relate to energy headroom report (EHR) and sustainable duty cycle (SDC) reporting for dynamic power aggregation. In one example, a user equipment (UE) may identify an available energy or available time period for an uplink transmission via uplink carrier aggregation or dual connectivity. The UE may further transmit, to a network entity, a report including the available energy or available time period for uplink transmission. In another example, a network entity may transmit a configuration message to configure the UE with carrier aggregation or dual connectivity. The network entity may further receive a report including the available energy or time for uplink transmission via carrier aggregation or dual connectivity. The network entity may further adjust uplink communication with the UE based on the received report.

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, a multicast message or a broadcast message that uses a radio link control (RLC) format associated with an RLC acknowledged mode (RLC-AM). The UE may decode the multicast message or the broadcast message to identify information associated with an RLC unacknowledged mode (RLC-UM) based at least in part on a capability of the UE. The UE may operate in accordance with the RLC-UM based at least in part on decoding the multicast message or the broadcast message. Numerous other aspects are provided.

Abstract: A wireless communication device can flexibly change subcarrier spacing (SCS) and/or cyclic prefix (CP) in wireless communication. The wireless communication device can transmit, in a first sidelink resource of a sidelink resource pool, a first sidelink transmission using a first configuration of suhcarrier spacing (SCS) and cyclic prefix (CP). The wireless communication device can further transmit, in a second sidelink resource of the sidelink resource pool., a second sidelink transmission using a second configuration of SCS and CP, the second configuration being different from the first configuration in terms of at least one of an SCS or a CP. The techniques allow more efficient switching between SCS and CP configurations withing a resource pool, in the same bandwidth part.
