    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, downlink control information that indicates a single precoder indication associated with non-codebook usage. The UE may transmit, to the base station, a single antenna-panel uplink transmission or a multiple antenna-panel uplink transmission based at least in part on a determination of whether the single precoder indication indicates the single antenna-panel uplink transmission or the multiple antenna-panel uplink transmission. 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 indication associated with multiplexing uplink control information (UCI) on a physical uplink shared channel (PUSCH), wherein the indication is associated with multiple component carriers (CCs) on which respective PUSCH transmissions are to be performed; identify one or more CCs, of the multiple CCs, to which the indication applies; and selectively transmit the UCI via the PUSCH on a CC, of the one or more CCs, in accordance with the indication. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a control message associated with an uplink transmission from one or more antenna panels. In some cases, the control message may include a first indication associated with an uplink transmission configuration indicator and a second indication of an uplink power control parameter set identifier associated with the first indication. In some cases, the control message may include a bit, where a value of the bit indicates whether an uplink transmission configuration indicator is included in the control message or an uplink power control parameter set identifier is included in the control message. The UE may then communicate with the base station based on receiving the control message.

    Abstract: Aspects described herein relate to detecting maximum permissible exposure (MPE) events and/or reporting the MPE event, related metrics, associated requests for beam switching or new time division duplexing (TDD) patterns, etc. In an aspect, a MPE event can be detected on at least one component carrier (CC) of multiple CCs configured with a first cell in inter-band carrier aggregation (CA), and one of a MPE report or a beam switching request can be transmitted to a second cell on a different CC of the multiple CCs. In another aspect, the cell can detect the MPE and can transmit, to the device, a beam switching command to switch to a new beam for uplink communications. In another aspect, the cell can transmitting, to another cell having another CC of the multiple CCs configured with the device, an indication to perform beam switching for the device.

    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: A user equipment (UE) and a base station may utilize downlink control information (DCI) based beam indication to switch beams for wireless communications. The base station may transmit and the UE may receive on a control beam for a control resource set (CORESET), a downlink control information (DCI) that includes a transmission configuration indicator (TCI) and schedules a transmission between the UE and the base station. The UE and the base station may communicate the scheduled transmission. The UE and the base station may determine an acknowledgment of the DCI based on the scheduled transmission. The UE and the base station may switch the control beam for the CORESET based on the TCI after a time offset from the acknowledgment.

    Abstract: Certain aspects of the present disclosure provide techniques for wireless communication. A method for wireless communication by a user equipment (UE) generally includes signaling, to a network entity, one or more capabilities of the UE for uplink panel switching associated with simultaneous multiple-panel (multi-panel) uplink transmission. The method generally includes receiving, from the network entity, an uplink panel switching configuration for the UE in response to the one or more capabilities of the CE.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of at least two timing advance groups (TAGs) per serving cell for multiple transmit receive point operation, wherein each TAG is associated with an uplink or joint transmission configuration indicator (TCI) state. The UE may receive an activation message that activates one or more TCI states for one or more uplink channels or reference signals. The UE may select a common TAG for the one or more uplink channels or reference signals based at least in part on a common TAG rule. The UE may transmit a reference signal or a communication on an uplink channel using the common TAG. Numerous other aspects are described.
