Abstract: An electronic device includes a transceiver and processing circuitry that is operatively coupled to the transceiver. The processing circuitry is configured to transmit, via the transceiver and to a second electronic device, a request for a wireless communication session with the second electronic device. The processing circuitry is also configured to communicate, via the transceiver, one or more first wireless signals during the wireless communication session with the second electronic device. Additionally, the processing circuitry is configured, after communicating the one or more first wireless signals, to extend the wireless communication session by transmitting, via the transceiver and to the second electronic device, one or more second wireless signals based on no wireless signals being communicated via the wireless communication session for a duration of time.

Abstract: Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.

Abstract: A terminal may include configured to receive, from a network, multiple downlink signals. The terminal may include a processor configured to identify, from the downlink signals, at least one configuration parameter including a bandwidth part switching indicator. The processor may then identify at least one resource from a target bandwidth part indicated by the bandwidth part switching indicator. The processor may then determine a bandwidth part mismatch based on whether a signal is received using the at least one resource from the target bandwidth part.

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 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.

CPC classification number: H04L5/0053
Abstract: The techniques provide solutions for a user equipment (UE) and base station to switch between T1R4 and 2T4R for sounding reference signals (SRS). The UE and base station may communicate SRS using 2T4R. The UE and/or base station may detect and evaluate a signal quality trigger and/or condition relating to switching from T2R4 to T1R4. The trigger and/or condition may correspond to a channel or radio frequency (RF) quality, conflicting or problematic band combinations used in a non-standalone (NSA) scenario, whether dedicated data subscription (DDS) subscriber identity module (SIM) or non-DDS SIM is being used in a dual SIM dual active (DSDA) scenario, etc. The UE and base station may either continue using T2R4 communications or switch to T1R4 communications based on the trigger and/or evaluation.

Abstract: Systems and methods for enhanced power control at a user equipment (UE) under poor channel conditions respective to antenna transmit diversity (ATD) mechanisms are discussed herein. In some embodiments, a UE may reset a transmit power control (TPC) power adjustment value when an ATD antenna switch of the ATD mechanism is performed. In some embodiments, a UE may reduce the value of an ATD hysteresis timer upon determining that a reference signal receive power (RSRP) change on a monitored reference signal that drives a pathloss calculation at the UE exceeds a threshold. In some embodiments, a UE may scale a filtering coefficient of a pathloss calculation mechanism upon determining that an RSRP change on a monitored reference signal that drives a pathloss calculation at the UE exceeds a threshold.
