Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more pathloss reference signals based at least in part on whether a configuration, that indicates a set of pathloss reference signals, has been received and based at least in part on whether a pathloss reference signal activation command has been received; and estimate pathloss using the one or more pathloss reference signals. 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 an activation command for a pathloss reference signal (PLRS). The UE may estimate a pathloss using the PLRS based at least in part on an applicable time for the PLRS that indicates a time at which the PLRS is to be ready for use in estimating the pathloss. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a message type for a random access message associated with a two-step random access channel procedure. The message type may be either a first message type or a second message type that is different from the second message type. The message type may be determined based at least in part on whether a signal strength satisfies a signal strength threshold. The user equipment may transmit the random access message based at least in part on the determined message type. 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 transmit, to a base station, an indication of whether the UE is enabled to receive a simultaneous spatial relation update for a physical uplink control channel (PUCCH) resource group of PUCCH resources that share a same spatial relation. The UE may receive, from the base station based at least in part on the indication, the simultaneous spatial relation update for the PUCCH resource group. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for dynamically updating transmission configuration information (TCI) state and spatial relation information. For example, downlink control information (DCI) or media access control control element (MAC-CE) is used to update a large number of TCI states. As such, high efficiency, such as in terms of low overhead or usage of memory, is achieved with an increase of the upper limit of configured trigger state numbers. The DCI or MAC-CE is used to dynamically update the content in the large number of TCI states.

Abstract: Various aspects of the present disclosure generally relate to indicating beams for user equipment beam reporting. In some aspects, a user equipment (UE) may receive, from a base station, an indication of a plurality of candidate beams on which the base station is able to simultaneously transmit communications to the UE, and determine a first beam and a second beam from among the plurality of candidate beams, based at least in part on one or more measurements of the plurality of candidate beams. The UE may transmit an indication of the first beam and the second beam to the base station, and receive communications simultaneously on the first beam and the second beam. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for processing transmissions with multiple beams. For example, the techniques may be implemented in wireless systems in which any type of network entity (gNB or transmission reception points TRPs) send directional transmissions to user equipments (UEs) that receive the directional transmissions with receive beams.
