Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate control signaling to a network entity comprising a time-varying beam correspondence indicator. In some examples, the network entity may transmit the time-varying correspondence indicator to the UE. In other examples, the UE may transmit the time-varying correspondence indicator to the network entity. The UE may select a first set of beam weight values for an uplink beam and a second set of beam weight values for a downlink beam based on the time-varying correspondence indicator. The UE may perform wireless communications with the network entity using the uplink beam according to the first set of beam weight values, the downlink beam according to the second set of beam weight values, or both.

Abstract: Methods, systems, and devices for wireless communications are described. Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support methods for selection of antenna arrays and beamforming feedback. In some cases, a user equipment (UE) may monitor for an antenna blockage condition at the UE and may select a set of antenna arrays for the UE for communications between the UE and a network entity based at least in part on whether the antenna blockage condition is detected, the set of antenna arrays selected from a multiple predetermined sets of antenna arrays of the UE. Additionally, the UE may transmit, to the network entity, a message indicative of whether the antenna blockage condition is detected and may communicate with the network entity using the set of antenna arrays in accordance with whether the antenna blockage condition is detected.

Abstract: A network device is provided that uses power measurements to measure a relative phase between a received signal from a reference antenna in a plurality of antennas and a received signal from each antenna in the plurality of antennas except the reference antenna. The network device may use a direct phase measurement to measure the phase of other received signals from additional antennas.

Abstract: The described techniques provide a first device configured to transmit, to a second device, an indication of a beam switching capability. In response, the second device schedules resources for a set of shared channel transmissions based on a first beam switching configuration. If the first beam switching configuration exceeds the beam switching capability of the first device, the first device applies a set of selection rules to the first beam switching configuration to obtain a second beam switching configuration and communicates with the second device according to the second beam switching configuration.

Abstract: The present disclosure provides for beam selection by a mobile device based on a sensor state of the mobile in order to mitigate hand blockage. The mobile device detects, during operation of the mobile device, a sensor state caused by a hand of an operator on the mobile device. The mobile device selects for communication, while operating in the sensor state, a refined beam set corresponding to the sensor state based on reference signals. The mobile device trains a machine learning model based on a set of training data including pairs of the sensor state and the refined beam set to select a first set of beam weights from a second set of beam weights based on a detected sensor state. The mobile device selects for communication a hand blockage state including the first set of beam weights for a current detected sensor state based on the machine learning model.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a first user equipment (UE) identifies a trigger condition associated with a first communication link with a base station and establishes a second communication link with a second UE. The UE may transmit a relay request to the second UE based on the trigger condition, wherein the relay request instructs the second UE to relay communications for the first UE. The first UE communicates with the base station via the second communication link. In another example, a base station establishes communication links with a first and second UE. The base station receives a data forwarding request that instructs the base station to use the second UE to relay communications between it and the first UE. The base station communicates with the first UE via the second communication link based at least in part on the relay request.
