Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive, from a network entity, control signaling identifying two or more transmission configuration indicator states that are to be applied to communications of one or more channels subsequent to a determined time; receive, from the network entity, control information associated with one or more resource allocations for communications after the determined time; and communicate via the one or more channels according to a first transmission configuration indicator state of the two or more transmission configuration indicator states based at least in part on a parameter associated with the control information and the two or more transmission configuration indicator states.

Abstract: One innovative aspect of the subject matter described in this disclosure can be implemented in a method for wireless communication. The method includes determining a configuration of reference signal (RS) resources to be used by a user-equipment (UE) to perform beam measurements, transmitting, to the UE, an indication of the configuration of the RS resources, and receiving, from the UE, a report indicating a plurality of RS resource indicators based on the beam measurements, each of the RS resource indicators being associated with one of the RS resources. In some aspects, the BS selects a subset of the RS resources based on the report from the UE, transmits, to the UE, an indication to provide channel measurement information for the subset of the RS resources, and receives a report including the channel measurement information from the UE. The BS may also perform joint precoding of signals for transmission via the RS resources based on the channel measurement information.

Abstract: Aspects described herein relate to detecting maximum permissible exposure (MPE) events and/or reporting cell metrics related to MPE events. A cell group metric for multiple cells configured in inter-band carrier aggregation (CA) can be measured. Based on the cell group metric, occurrence of a maximum permissible exposure (MPE) event can be detected, and/or the cell group metric can be reported to one or more cells of the multiple cells based on detecting occurrence of the MPE event.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may support multiple communications schemes, including a time division multiplexing (TDM) scheme, a frequency division multiplexing (FDM) scheme, a spatial division multiplexing (SDM) scheme, and a single transmission/reception point (sTRP) scheme. The UE may receive control signaling that indicates the multiple communications schemes and downlink control information (DCI) that schedules an uplink data message. The DCI may indicate one or more sounding reference signal (SRS) resource sets associated with the uplink data message. The UE may transmit the uplink data message in accordance with a switching arrangement for switching between the communications schemes. The switching arrangement may be indicated for the uplink data message by one or more of the control signaling, the DCI, or the one or more SRS resource sets.

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, a virtual power headroom report (PHR) that is based at least in part on a beam-specific pathloss reference signal (PLRS). The UE may receive, from the base station, a downlink transmission based at least in part on the virtual PHR. Numerous other aspects are described.

Abstract: A user equipment (UE) detects beam failure associated with a transmission/reception point (TRP) of a plurality of TRPs transmitting to the UE. Each TRP is associated with separate Physical Uplink Control Channel (PUCCH) resources for beam failure recovery (BFR). The UE applies, in response to detecting, a BFR procedure across PUCCH resources of the TRPs. In some aspects, the procedure is described by a single set of parameters/variable (s) across the PUCCH resources. Further, each of a plurality of TRPs transmits to a UE on a beam. A first of the TRPs receives, from the UE, a scheduling request (SR) in BFR PUCCH resources. The SR indicates that an uplink grant is requested by the UE to transmit beam failure information for at least one failed beam of the TRPs. The SR is a result of a single BFR procedure applied by the UE across the PUCCH resources of the TRPs.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for a sounding reference signal (SRS) resource set configuration to facilitate uplink panel selection between a set of asymmetric panels of a user equipment (UE), each panel of the set of asymmetric panels of the UE being associated with a different number of SRS ports. In one aspect, the UE may receive such an SRS resource set configuration indicating one or more SRS resource sets and SRS resources of the one or more SRS resource sets may be associated with different numbers of SRS ports or a dynamically configurable number of SRS ports. The UE may receive control signaling from a base station (BS) and the control signaling may indicate a panel for an uplink transmission from the UE by indicating an SRS resource, an SRS resource set, or a number of SRS ports.

Abstract: Downlink schemes are disclosed for a cooperative user equipment (UE) with joint baseband processing. UEs may establish a cooperative UE unit with one or more neighboring UEs, where one of the UEs operates as the primary UE. The participating UEs of the cooperative UE unit determine a downlink transmission scheme for the cooperative transmissions from a serving base station and receive cooperative transmissions of one or more transport blocks from the serving base station according to the downlink transmission scheme. The secondary UEs of the cooperative UE unit generate and transmit cooperative process data to the primary UE, where the cooperative process data is based on the receipt of the cooperative transmissions by the secondary UEs. The primary UE processes its received cooperative transmission along with the cooperative process data to decode the one or more transport blocks. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first control message indicating an uplink power control configuration for the UE. The uplink power control configuration may be associated with a power control identifier and a resource set identifier. The UE may receive a second control message that schedules an uplink message for the UE. The second control message may indicate the resource set identifier and the power control identifier for transmission of the uplink message. The UE may determine a transmit power for the uplink message based on a set of power control parameters, the set of power control parameters corresponding to the resource set identifier and the power control identifier. The UE may transmit the uplink message using a resource set associated with the resource set identifier and in accordance with the determined transmit power.
