Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to switch a beam used by the UE, wherein the indication triggers at least one of a reference signal for a beam measurement or a transmission of a measurement report, based at least in part on an association of the beam with the reference signal or the measurement report. The UE may receive the reference signal associated with the beam measurement based at least in part on receiving the indication to switch the beam. The UE may transmit, using one or more transmission parameters, the measurement report indicating a measurement of the reference signal, wherein the one or more transmission parameters are based at least in part on receiving the indication to switch the beam. Numerous other aspects are described.

Methods and apparatuses for transmission or reception using beamforming in a wireless communication system are disclosed herein. In one method, a user equipment receives a second signal indicating a first information. The UE derives at least one specific UE beam based on the first information. The UE uses the at least one specific UE beam to receive or transmit at least one transmission, in which the at least one transmission is periodic channel state indication, scheduling request, and/or scheduling information for downlink assignment or uplink resource.

Provided are a beam recovery processing method, a beam recovery method, a base station and a terminal. The beam recovery processing method includes: determining, by a transmitting end, a configuration information set for instructing a receiving end to perform a beam recovery; and transmitting, by the transmitting end, the configuration information set to the receiving end.

Certain aspects of the present disclosure provide techniques for using multiple timing advances for simultaneous uplink reception, for example, using multiple antennas, beams, and/or antenna panels. A method that may be performed by a user equipment (UE) includes configuring a plurality of timing advances (TAs) for a plurality of uplink transmissions using a plurality of antennas. The UE transmits the plurality of uplink transmissions to a base station (BS) using the plurality of antennas based on the plurality of timing advances. A method that may be performed by a BS includes receiving a plurality of uplink transmissions from a UE and transmitting timing information to the UE in a message, the timing information based on when each of the plurality of uplink transmissions was received at the BS.

A terminal according to one aspect of the present disclosure includes: a receiving section that receives a Downlink Control Information (DCI) format 0_0 for scheduling a Physical Uplink Shared Channel (PUSCH) within a bandwidth part or a cell to which a Physical Uplink Control Channel (PUCCH) resource with spatial relation information is not configured when a higher layer parameter satisfies a condition; and a control section that determines a spatial relation for the PUSCH. According to one aspect of the present disclosure, it is possible to appropriately transmit UL transmission.

A wireless device (10) sends LBT (listen before talk) based uplink wireless transmissions on a serving transmission beam (22) to an access node (100-1, 100-2). The serving transmission beam (22) is selected from a plurality of transmission beams (21, 22, 23). Further, the wireless device (10) detects LBT failures on the serving transmission beam (22). Based on the number of the detected LBT failures on the serving transmission beam (22), the wireless device (10) sends a failure report to the access node (100-1, 100-2. The failure report indicates the detected LBT failures on the sewing transmission beam (22).

A communication resource unit allocation method, includes: receiving a message sent by a second radio communication device, wherein the message comprises an information element indicating a number of antennas of the second radio communication device.

In a multiuser (MU) multiple antenna system (MAS), a central processing unit is communicatively coupled to multiple distributed wireless terminals (WTs) via a network. The central processing unit processes channel measurements indicative of channel conditions between the multiple distributed WTs and a plurality of user devices and selects a plurality of WTs from the multiple distributed WTs to enhance channel space diversity within the MU-MAS. The central processing unit calculates (Multiple Input, Multiple Output) MIMO weights from the channel measurements for precoding a plurality of data streams that are transmitted concurrently from the plurality of WTs to the plurality of users, wherein the MIMO weights provide for a plurality of independent MIMO channels.

An information processing method and apparatus, a terminal, and a communications device are provided. The method includes: determining, based on detection of a reporting trigger event, whether to report an event-based beam report and/or an event-based channel state information (CSI) report to a network-side device.

A communications method and apparatus to implement radio frequency link sharing, improve radio frequency link utilization, and increase an uplink transmission rate. The method includes a terminal that receives first configuration information and second configuration information from a first network device. The first configuration information is used to indicate a first reference signal resource of a first antenna port, and the second configuration information is used to indicate a second reference signal resource of a second antenna port; or the first configuration information is used to indicate a third reference signal resource of a first quantity of antenna ports, and the second configuration information is used to indicate a fourth reference signal resource of a second quantity of antenna ports. The terminal sends a first reference signal based on the first configuration information and sends a second reference signal based on the second configuration information.
