    Abstract: Aspects are provided which enhance Mode 2 multi-TRP operation by allowing a UE to recover and reconfigure a failed PDCCH beam of a first TRP in a serving cell by using a second TRP which still has a working PDCCH in the same serving cell. If the first TRP undergoes beam failure but the second TRP in the same cell has an operational beam, the UE may send a beam failure indication indicating a new beam for the PDCCH of the first TRP. The base station comprising the second TRP may then reconfigure the PDCCH serving beams of the first TRP based on the beam failure indication. The reliability of a serving cell may thus be increased.

    Abstract: Certain aspects of the present disclosure provide techniques for supporting multiple semi-persistent resource allocations per serving cell. Embodiments include determining an association between one or more semi-persistent resource allocations and one or more identifiers. Embodiments include receiving signaling indicating activation or deactivation of at least one of the one or more semi-persistent resource allocations. Embodiments include determining an identifier of the at least one of the one or more semi-persistent resource allocations based on the association. Embodiments include sending an acknowledgment of the activation or deactivation. The acknowledgment may indicate the identifier of the at least one of the one or more semi-persistent resource allocations.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit to a base station (BS), information indicating a medium access control (MAC) security capability of the UE. The UE may receive from the BS, a communication that includes an indication of a MAC security configuration for communications between the UE and the BS. The indication of the MAC security configuration may be based at least in part on the MAC security capability of the UE. Numerous other aspects are provided.

    Abstract: Aspects presented herein provide an enhanced power management solution, such that an apparatus may configure a UE with more than one DRX configuration for different cells. The apparatus determines a configuration of a plurality of discontinuous reception (DRX) groups for communicating with a UE. The apparatus configures the UE with a first DRX group for a first set of serving cells. The apparatus configures the UE with a second DRX group for a second set of serving cells.

    Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.
