Abstract: Methods, systems, and devices for wireless communication are described. According to one or more aspects, the described apparatus includes one or more stacks of patch radiators (such as patch antennas) comprising at least a first patch radiator and a second patch radiator. The first patch radiator is associated with a low-band frequency; the second patch radiator is associated with a high-band frequency. The first patch radiator and the second patch radiator may overlap a ground plane, which may be asymmetric. Some or all patch radiators in a stack may be rotated relative to the ground plane, such that some or all edge of a patch radiator may be nonparallel with one or more edges of the ground plane. Further, each patch radiator stack may include separate feeds for each of at least two frequencies and two polarizations, and thus at least four feeds (one for each frequency/polarization combination) in total.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a user equipment (UE) may receive a control message indicating a reference signal configuration for beam calibration by the UE based on a beamforming characterization status. The UE may receive a set of beam calibration reference signals based on the reference signal configuration. The UE may measure the set of beam calibration reference signals and generate a set of beamforming weights for use in communications by the UE based on the measuring and the beamforming characterization status. In some cases, the UE may transmit or forward a beamforming codebook based on the beamforming weights to a network entity. The network entity or the UE may forward the beamforming codebook to other UEs of a same design class as the UE.

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.
