BEAMFORMING CODEBOOK ADAPTATION FOR FLEXIBLE WIRELESS DEVICES

Abstract: methods, systems, and devices for wireless communications are described. a codebook adaptation may be performed for a flexible user equipment (ues) to determine a codebook for a physical configuration of the ue. for example, if the ue determines that the physical configuration does not correspond to a pre-loaded codebook in its memory, the ue may provide information about the physical configuration to a base station to determine a corresponding codebook. additionally, the ue may request that the base station provide channel information to assist with the codebook determination. in some cases, this request may indicate for the base station to allocate a specific number of channel state information reference signal symbols that the ue can use for the codebook determination. additionally or alternatively, the ue may generate the codebook internally and then signal to the base station a request for a beam refinement procedure with the generated codebook.
