Methods for selection of antenna arrays and beamforming feedback

An apparatus for wireless communications at a user equipment (UE), comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors, the one or more memories storing instructions executable by the one or more processors to cause the apparatus to:
• monitor for an antenna blockage condition at the UE;
• switch to a set of one or more antenna arrays of the UE for communications between the UE and a network entity, the set of one or more antenna arrays selected from a plurality of predetermined sets of antenna arrays of the UE based at least in part on whether the antenna blockage condition is detected;
• transmit, to the network entity based at least in part on the set of one or more antenna arrays being switched to, a message indicative of whether the antenna blockage condition is detected;
• and
• communicate with the network entity using the set of one or more antenna arrays in accordance with whether the antenna blockage condition is detected.

An apparatus for wireless communications at a network entity, comprising:

• one or more processors;
• and
• one or more memories coupled to the one or more processors, the one or more memories storing instructions executable by the one or more processors to cause the apparatus to:
• receive a message indicative of whether an antenna blockage condition is detected at a user equipment (UE) that includes a plurality of antenna arrays based at least in part on the UE switching to a set of one or more antenna arrays of the plurality of antenna arrays;
• switch to a set of one or more communication parameters for communications between the UE and the network entity based on receiving the message, the set of one or more communication parameters selected from a plurality of sets of communication parameters that each correspond to communications with the UE via respective predetermined sets of antenna arrays of the UE, wherein the set of one or more communication parameters correspond to communications with the UE via the set of one or more antenna arrays switched to by the UE;
• and
• communicate with the UE in accordance with the set of one or more communication parameters.
