Abstract: Methods, systems, and devices for wireless communications are described. Multiple user equipments (UEs) may communicate as part of a sidelink communications system. The UEs may identify a frame for a sidelink connection. The frame may include a control portion and a data portion. One UE of a pair of UEs may receive a data signal from the other UE of the pair, and the data signal may be received in the data portion of the first instance of the frame and in the control portion of a second instance of the frame. Another pair of UEs may attempt to reserve a subsequent data portion by transmitting a request signal in the control portion in the second instance of the frame, and the second pair of UEs may receive a suppression signal from the first pair of UEs indicating ongoing data transmission by the first pair of UEs.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may detect a material proximate to the UE and may determine one or more properties of the material which may affect beamformed communications. The UE may transmit (e.g., based on the detected material) an indication of a switch from a codebook-based hybrid beamforming procedure to an adaptive beam weight-based hybrid beamforming procedure. The UE may receive, from a network entity, one or more reference signals to use for adaptive beam weight selection in response to the indication of the switch to the adaptive beam weight-based hybrid beamforming procedure. The UE may communicate, with the network entity, in accordance with one or more beam weights selected based on the adaptive beam weight-based hybrid beamforming procedure and the one or more reference signals.

Abstract: Aspects of the disclosure relate to beam management systems and procedures. In one example, a network node is configured to determine beam-specific gain adjustments for use with a set of wireless communication beams, wherein the wireless communication beams have one or more different beamformed spatial orientation parameters. The network node is also configured to apply the beam-specific gain adjustments to wireless communications with an access terminal. In another example, an access terminal is configured to receive beam-specific gain adjustments from a network node for use with a set of wireless communication beams, wherein the wireless communication beams have one or more different beamformed spatial orientation parameters. The access terminal is also configured to apply the beam-specific gain adjustments to wireless communications with the network node. Hierarchical beam management systems and procedures are also described. Illustrative examples exploit frequencies above 24.25 gigahertz (GHz).

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus of a user equipment (UE) may transmit a power headroom (PHR) parameter. The PHR parameter may be based at least in part on a beam being associated with a grating lobe and a main lobe. A power of the grating lobe may be within a power threshold of a power of the main lobe. The apparatus may perform a communication using the beam based at least in part on the PHR parameter. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, control signaling indicating a capability of the UE to apply an amplitude control procedure to one or more antenna elements for beamforming and indicating that the UE is applying the amplitude control procedure. The UE may receive a control message scheduling transmission of an uplink message. The UE may generate a signal including the uplink message using the amplitude control procedure, which may adjust one or more amplitudes of the signal. The UE may transmit the signal via the one or more antenna elements. In some cases, UE may indicate an amount of power loss in the signal based on the amplitude control procedure, and the base station may transmit downlink transmissions using a lower order modulation and coding scheme or an applied power boost to compensate for the power loss.

Abstract: Methods, systems, and devices for wireless communications are described in which a first wireless device and second wireless device may establish communications using a first beam and a second beam. The first wireless device may perform separate radio link monitoring (RLM) procedures to monitor beam quality for each of a transmit beam and receive beam that are used for communications with a second wireless device. The separate RLM procedures may be used at the first wireless device to determine that one of the transmit or receive beams is experiencing a quality degradation or a radio link failure (RLF), and an RLF indication may be provided to the second wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. Aspects may include a base station coordinating a first UE and a second UE establishing relay link for directly communicating with one and other. In some cases, the relay link may be a beamformed relay link and the base station and one of the UEs may use to the relay link to communicate if a direct communication link between the base station and the UE fails. The base station may transmit reference signal information to the first and second UE for establishing a relay link. The first and second UE may perform one or more relay link beam sweeping procedures based on the reference signal information and establish the relay link based on the beam sweep procedures. In some cases, coordinating the relay link may be based on one of the UEs transmitting a triggering message to the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a multi-panel device may determine, for each antenna panel of the multi-panel device, a coverage region over which the multi-panel device may communicate using that antenna panel based on an array gain pattern of that antenna panel. For example, the multi-panel device may determine, for each antenna panel of the multi-panel device, a coverage region over which the multi-panel device may communicate using that antenna panel to avoid the formation of a grating lobe from that antenna panel. The multi-panel device may dynamically adjust the coverage regions associated with the antenna panels of the multi-panel device based on determining that an interference metric exceeds a threshold interference level or based on determining that a power or thermal condition of the multi-panel device fails to satisfy a power or thermal constraint of the multi-panel device.
