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: Certain aspects of the present disclosure generally relate to radio frequency (RF) front-end circuitry. For example, certain aspects provide an apparatus having a first converter circuit configured to upconvert a first baseband (BB) signal to a first RF signal based on a mode of operation, and a second converter circuit configured to upconvert a second BB signal to a second RF signal based on the mode of operation. The apparatus also includes a first RF weight adjustment circuit configured to selectively apply an amplitude weight or a phase weight to at least one of the first RF signal or the second RF signal based on the mode of operation, and a controller configured to control a power state of the second converter circuit in dependence on the mode of operation.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity, a first indication of one or more antenna element selection parameters including one or more antenna element performance thresholds for antenna element selection by the UE. The UE may select one or more antenna elements based on the one or more antenna elements satisfying the one or more antenna element performance thresholds. The UE may transmit, to the network entity, a second indication of one or more transmission configuration indicator (TCI) states that correspond to the usage of the one or more antenna elements selected by the UE.
