Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for TCI state activation and deactivation under multiple transmit receive point (TRP) operation. In some aspects, a number of activated transmission configuration indicator (TCI) states, and TCI state types, can be indicated using a single codepoint. In some implementations, codepoints may include multiple TCI states. Each TCI state identifier in the codepoint may correspond to a TCI state type, such as uplink, downlink, or both. In some implementations, the base station (BS) may configure two separate TCI state lists, one for downlink and one for uplink. Each codepoint may include an indication of one of the two configured lists with which the TCI state identifier is associated. In some implementations, the BS may configure two bitmaps, where a first bitmap corresponds to downlink TCI states, and a second bitmap corresponds to uplink TCI states.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a serving cell, information indicating a set of activated channel state information (CSI) trigger states that are respectively associated with a set of transmission configuration indication (TCI) states each having a respective source reference signal. The UE may track, based at least in part on a capability to concurrently track multiple TCI states, a subset of TCI states, of the set of TCI states, including at least one TCI state for which the respective source reference signal is a non-serving cell synchronization signal block (SSB). Numerous other aspects are provided.

Abstract: To facilitate TCI state update and activation to provide common QCL information, methods, apparatuses, and computer-readable storage medium are provided. An example method includes receiving, from a network entity (e.g., a base station), an indication indicating a reference bandwidth part (BWP) or component carrier (CC) for a common transmission configuration indicator (TCI) pool shared by a set of BWPs or CCs. The example method further includes communicating with the network entity (e.g., the base station) based on the reference BWP or CC.

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 beam report that indicates that the UE is to switch to a beam for a physical uplink channel. The UE may switch to the beam a specified time offset after one of: transmitting the beam report to the base station, receiving a beam switch response from the base station in response to the beam report, or a scheduled communication on the physical uplink channel. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a user equipment (UE) may receive downlink control information (DCI) from a base station, indicating a set of codepoints corresponding to a set of beam configurations, and including an uplink grant. The UE may select a codepoint from the set of codepoints corresponding to a default uplink beam for transmitting an uplink message based at least in part on a beam configuration selection criteria that indicates criteria for selecting a subset of valid beam configurations from the set of beam configurations. The UE may transmit the scheduled uplink message according to the uplink grant using the default uplink beam.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit an indication of support for one or more of panel-specific reporting or beam-specific reporting of maximum permissible exposure (MPE) parameters. The UE may receive an indication to report the MPE parameters with panel-specific reporting or beam-specific reporting. Numerous other aspects are described.

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 beam failure recovery request based at least in part on a beam failure between a transmit-receive point (TRP) of the base station and a panel of the UE. The UE may receive, from the base station, a beam failure recovery response based at least in part on the beam failure recovery request. The UE may perform, to the base station, an uplink channel transmission based at least in part on per-TRP-and-panel power control parameters that are associated with the TRP and the panel. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for allocating channel state information (CSI) processing unit (CPU) for user equipment (UE) initiated CSI. For example, the UE may receive an indication from a network entity (e.g., a base station or gNB) configuring the UE with a number of one or more CPUs allowed to be occupied for UE-initiated CSI feedback. The UE uses the at least one of the CPUs to calculate UE-initiated CSI feedback. The UE transmits at least one report including the UE-initiated CSI feedback if one or more conditions are met, such as when a mismatch between a CSI metric for a scheduled physical downlink shared channel (PDSCH) and a CSI metric calculated as part of the UE-initiated CSI feedback is equal to or exceeding a threshold value.

Abstract: Certain aspects of the present disclosure provide techniques for interference avoidance in full duplex communications. A method that may be performed by a user equipment (UE) includes transmitting, to a network entity, a request to provide a configuration for interference avoidance between a first signal and a second signal, wherein the first signal is scheduled in a same transmission occasion as the second signal is scheduled for reception. The method further includes receiving, from the network entity, the configuration and configuring resources for at least one of transmission of the first signal or reception of the second signal in response to receiving the configuration. The method also includes transmitting the first signal via the configured resources and receiving the second signal in the transmission occasion.

Abstract: Methods, systems, and devices for wireless communications are described. A unified transmission configuration indicator (TCI) framework may be implemented by a wireless communication system may support joint common TCI states for downlink and uplink channels or reference signals associated with communications between devices. A base station may transmit downlink control information (DCI) to a user equipment (UE) indicating the one or more TCI states and a scheduling for a downlink channel. The UE may transmit an acknowledgment message that is either an explicit acknowledgement or an implicit acknowledgment to confirm whether the one or more TCI states were successfully received in the DCI.
