Disclosed herein are a method and a device for transmitting an uplink channel in a wireless communication system. According to the present disclosure, a UE transmits to a base station information associated with uplink transmission supported by the UE and the UE information includes a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive from the base station uplink transmission information including a TPMI for transmitting an uplink channel and transmit to the base station the uplink channel based on the uplink transmission information, and the uplink channel may be transmitted through full transmission power configured by the base station based on a case where the TPMI is included in the subset.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may receive at least two reference signals from a base station. The apparatus may determine CSI associated with at least one of the at least two reference signals. The apparatus may determine at least one parameter based on the CSI. The apparatus may transmit, to the base station, the at least one parameter and the CSI to enable a predicted CSI to be determined based on the at least one parameter and the CSI. The apparatus may receive data or control information from the base station based on predictive CSI determined by the base station using the transmitted at least one parameter and CSI.

A terminal includes a transmission unit configured to transmit, to a base station, information indicating whether or not transmission diversity is supported, a reception unit configured to receive, from the base station, information indicating a transmission diversity scheme in a case where transmission diversity is supported, and a control unit configured to switch to a transmission diversity scheme based on the information indicating the transmission diversity scheme, wherein the transmission unit is configured to perform transmission by applying the transmission diversity scheme to which the switch was made.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a capability message indicating at least one of parameters associated with one or more beam management features or whether the UE supports the one or more beam management features, the one or more beam management features including a unified transmission configuration indicator (TCI) state, inter-cell beam measurements, antenna-panel-specific uplink transmissions, or multiple transmission reception point (TRP) beam failure recovery. The UE may receive configuration information for at least one beam management feature based at least in part on transmitting the capability message. Numerous other aspects are provided.

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for techniques for beam failure detection and recovery. A UE may support autonomous determination of a beam failure timer for a beam failure procedure, such as a beam failure detection (BFD) timer for a BFD procedure or a beam failure recovery (BFR) timer for a BFR procedure. For example, a network entity may transmit reference signals to the UE that are associated with the beam failure procedure. For instance, the UE may measure the reference signals as part of a BFD procedure or may initiate a BFR procedure in response to receiving the reference signals. The UE may determine a timer value for the beam failure timer using, for example, a machine learning (ML) model or a mapping and may perform the beam failure procedure in accordance with the UE-determined beam failure timer.

Certain aspects of the present disclosure provide techniques for beam switching gaps. An example method by a user equipment (UE) generally includes receiving signaling, from a network entity, indicating a beam switch from a first beam to a second beam, performing the beam switch from the first beam to the second beam, identifying a gap time after the beam switch when one or more conditions are met, and communicating with the network entity, after the gap time, using the second beam.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a first sounding reference signal (SRS) configuration, wherein the first SRS configuration indicates a number of antenna ports on which an SRS is to be transmitted. The UE may determine that the number of antenna ports indicated by the first SRS configuration exceeds an antenna capability of the UE. The UE may transmit one or more SRSs using a second SRS configuration based at least in part on determining that the first SRS configuration exceeds the antenna capability of the UE. Numerous other aspects are described.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a control message indicating a capability of the UE to identify and report a reciprocity parameter between downlink communications and uplink communications of a channel between the UE and the base station. In some examples, the base station may request a reciprocity report from the UE. The UE may identify a reciprocity parameter based on one or more parameters associated with an array of antennas at the UE. The reciprocity parameter may indicate a reciprocity between an uplink beam and a downlink beam, such as a degree of overlap between the uplink beam and the downlink beam. The UE may report the reciprocity parameter via a reciprocity report to the base station. In some examples, the base station may identify one or more parameters based on the reciprocity report.

The present disclosure relates to electronic device, method for wireless communication system and storage medium. The present disclosure proposes an electronic device on a control device side for a wireless communication system, comprising: a processing circuit configured to group a plurality of terminal devices of the wireless communication system into one linear precoding terminal device group and one or more nonlinear precoding terminal device groups based on respective nonlinear precoding capabilities and channel state information of the plurality of terminal devices; and notify each terminal device whether nonlinear precoding or linear precoding is to be employed in communication for the terminal device by means of a nonlinear precoding indicator based on the grouping.

A method and apparatus for performing beam failure recovery in a wireless communication system are disclosed. A method for performing beam failure recovery by a user equipment according to embodiment of the present disclosure may include transmitting, to a base station, capability information including a maximum number of BFD-RSs per a BFD-RS set supported by the UE and receiving, from the base station, configuration information including information related to at least one BFD-RS set, and each of the at least one BFD-RS set may include the maximum number of BFD-RSs or less.
