Abstract: A base station may transmit a quasi-collocation (QCL) relationship indication to a user equipment (UE) that indicates different QCL groups (e.g., QCL relationships corresponding to different port groups). The QCL relationship indication may include a tuple of transmission configuration indication (TCI)-states, TCI-states configured with TCI-state-sets, or multiple TCI-states indicated via an extended media access control (MAC) control element (CE). The QCL relationship indication may indicate a QCL relationship between one or more port groups of a first reference signal set and a plurality of port groups associated with a target reference signal. For example, the QCL relationship indication may indicate two QCL groups, where each QCL group includes a QCL relationship between a reference signal resource and a port group associated with a target reference signal. Using QCL group information, the UE may perform channel estimation for demodulating target reference signals, using the QCL antenna port group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may transmit an indication to a base station to configure a control channel of a downlink beam in accordance with a full duplex failure detection control resource set (CORESET), wherein the full duplex failure detection CORESET is used based at least in part on the UE being associated with a full duplex communication link that includes the downlink beam and an uplink beam; and monitor a reference signal on the control channel of the downlink beam based at least in part on the full duplex failure detection CORESET in order to detect a beam failure on the downlink beam while transmitting the uplink beam, wherein monitoring the reference signal is based at least in part on a threshold that is based on one or more uplink transmission parameters. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for data transmission in synchronization slots. A method for use by a base station for data transmission in synchronization slots includes transmitting a synchronization signal (SS) burst, wherein different SS blocks of the burst are transmitted using different transmit beams and performing frequency division multiplexing (FDM) or time division multiplexing (TDM) to include one or more other types of signals that need to be multicast and are also transmitted using the different transmit beams.

Abstract: A base station (BS) can determine a beamforming configuration for communicating with a user equipment (UE) using aggregated slots or mini-slots, wherein the beamforming configuration can comprise multiple beamformed channels. The BS can then indicate, and the UE can identify, the beamforming configuration. The BS and the UE can then communicate with each other across the aggregated slots or mini-slots based on the beamforming configuration. Also, the BS and the UE can transmit and/or receive a transport block across the aggregated slots or mini-slots.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to channel state operations using full-duplex communication. One example method generally includes receiving at least one channel state information-reference signal (CSI-RS) from a base station, transmitting at least one sounding reference signal (SRS) to the base station, wherein the CSI-RS is received simultaneously with the transmission of the at least one SRS, and transmitting, to the base station, at least one channel state feedback message comprising channel state information based on the at least one CSI-RS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may provide, to a first cell, a beam failure indication associated with a beam of a secondary cell. The beam failure indication may be provided via a dedicated physical uplink control channel (PUCCH) resource. The user equipment may provide, based at least in part on providing the beam failure indication, a beam index report to a second cell. The beam index report may be provided to cause recovery of the secondary cell to be triggered. The beam index report may include information that identifies a preferred beam associated with the recovery of the secondary cell. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Uplink random access channel (RACH) transmissions may be sent on multiple beams by a user equipment (UE). For example, a UE may transmit a random access preamble to a base station in a first RACH transmission, and the base station may respond with a random access response in a second RACH transmission. The second RACH transmission may include an indication for the UE to use multiple transmit beams for a third RACH transmission. Using the indication received from the base station, the UE may proceed to use the indicated two or more beams when sending the third RACH transmission to the base station. Upon receiving the third RACH transmission from the UE, the base station may respond with a fourth RACH transmission, which may further include an indication to the UE to transmit an acknowledgment using one or more beams.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a downlink traffic query to a base station based at least in part on an expectation of downlink traffic from the base station over an unlicensed frequency spectrum band and an absence of downlink traffic from the base station over the unlicensed frequency spectrum band for a threshold duration of time. The UE may receive a downlink traffic indication response from the base station based at least in part on the downlink traffic query. The UE may monitor the unlicensed frequency spectrum band based at least in part on the downlink traffic indication response.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine, during a beam failure recovery period, that a configured control resource set at least partially overlaps with a beam failure recovery control resource set. The UE may configure, based at least in part on the at least partial overlap, a receive beam to receive the beam failure recovery control resource set. The UE may receive a control signal over the beam failure recovery control resource set during the beam failure recovery period.

Abstract: Aspects described herein relate to transmitting a set of downlink reference signals corresponding to a set of uplink beams, receiving, from a user equipment (UE) and based on measuring at least one of the set of downlink reference signals, an indication to use a separate uplink beam that is different from a downlink beam for transmitting uplink communications, configuring, based on the indication, the UE with the downlink beam and the separate uplink beam, and receiving, from the UE, uplink communications based on the separate uplink beam.
