Abstract: The present disclosure relates to dynamic antenna array reconfiguration and signaling in millimeter wave bands. A user equipment (UE) may detect an antenna array change condition. The UE may transmit a request for beam training for an antenna array configuration in response to the detecting. The request for beam training may include a requested antenna array configuration for the UE and an indication of beam weights to use with the requested antenna array configuration. A base station may determine whether to grant or deny the requested antenna array configuration for the UE. The UE may receive, from the base station, an indication of an antenna array configuration for the UE. The base station may transmit the number of reference signals as a set of contiguous channel state information reference signals (CSI-RS). The UE may train the reconfigured active antenna array configuration based on the reference signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a network node, a polarization performance loss indication that is indicative of a loss in polarization performance based on transitioning from a first operating state associated with a first frequency range to a second operating state associated with a second frequency range, wherein the first operating state corresponds to a first antenna configuration and the second operating state corresponds to a second antenna configuration, wherein the first antenna configuration corresponds to a first antenna orientation and the second antenna configuration corresponds to a second antenna orientation. The UE may receive, from the network node, configuration information indicative of at least one communication parameter associated with the at least one antenna array and based on the polarization performance loss indication. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A receiver may orient its antenna arrays based on signaling from a transmitter and a distance between the receiver and the transmitter. The transmitter may transmit an indication of an orientation of its antenna array. The receiver may receive the indication and may determine the distance between the receiver and the transmitter. Based on whether the distance between the receiver and the transmitter satisfies a threshold distance from the transmitter, the receiver may select an orientation for its antenna array. The receiver may select a first antenna orientation based on the distance failing to satisfy the threshold distance and may select a second orientation based on the distance satisfying the threshold distance

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may utilize parameterized codebooks to support reconfigurable intelligent surface (RIS)-assisted communications. For example, a network entity may receive an indication of one or more codebooks associated with respective sets of parameters including one or more of a respective field of view (FOV) or a respective configuration switching latency, among other parameters. The network entity may select a codebook for RIS-assisted communications based on whether the codebook satisfies one or more thresholds. The network entity may indicate the codebook to a RIS controller and may communicate one or more messages with a user equipment (UE) using a RIS in accordance with the indicated codebook.
