Abstract: This disclosure relates to techniques for performing radio link monitoring and cell searching when moving at high speeds. A movement speed of a wireless device may be determined. When performing a cell search, the manner of the cell search may depend on the movement speed of the wireless device, potentially including cells that are associated with high movement speed being more highly prioritized when the wireless device is determined to be at a higher movement speed than when the wireless device is determined to be at a lower movement speed.

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: This disclosure relates to techniques for a wireless device to detect and operate in an elevator or elevator-like conditions. The wireless device may establish a cellular link with a cellular base station. One or more conditions associated with being in an elevator may be detected. The wireless device may determine to operate in an elevator mode based at least in part on detecting the one or more conditions associated with being in an elevator. The wireless device may operate in the elevator mode. One or more conditions associated with exiting an elevator may be detected. The wireless device may determine to operate in a normal mode based at least in part on detecting the one or more conditions associated with exiting an elevator. The wireless device may operate in the normal mode.
