Abstract: This disclosure relates to techniques for multi-RAT and DSDA capable wireless devices to handle frame blanking in a wireless communication system. A wireless device may establish wireless links according to a first radio access technology and a second radio access technology. The wireless device may determine to perform transmit and receive blanking for one or more antennas of the wireless device for the first radio access technology to perform sounding reference signal transmissions for the second radio access technology based at least in part on a band combination for the wireless links. The wireless device may determine a modification to channel state feedback reporting for the first radio access technology based at least in part on the transmit and receive blanking. The wireless device may perform channel state feedback reporting using the determined modification.

Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for storing a codebook in an integrated circuit. One of the methods includes storing, for an integrated circuit that comprises a memory, first data for a codebook in the memory; determining second data for the codebook using the first data; and sending, over a bus, the second data for the codebook to an antenna module separate from the integrated circuit.
