Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for configuring a power savings signal in fifth generation (5G) new radio (NR) networks. The wireless device may transmit, to a base station within a network, power savings requirements and receiving, from the base station, a configuration of a power saving signal, where the configuration indicates one or more functionalities of the power saving signal. The wireless device may periodically receive, from the base station, the power saving signal and interpret the power saving signal based on the configuration. The configuration of the power saving signal may be received via radio resource control signaling.

Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including performing one or more of periodic beam quality measurements and/or event-based beam quality measurements, determining, based at least in part on one or more of the periodic beam quality measurements and/or the event-based beam quality measurements, a recommended beam quality measurement configuration, and transmitting, to a base station serving the UE, the recommended beam quality measurement configuration. In addition, the UE may perform receiving, from the base station, instructions regarding the beam quality measurement configuration. The instructions may include instructions to activate, deactivate, and/or modify at least one beam quality measurement configuration. In addition, the instructions may be based, at least in part, on the recommended beam quality measurement configuration.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for determining resources for scheduling side-link communications. The resources may be semi-persistent and/or dynamic resources. A user equipment device (UE) may determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node. The UE may transmit a resource map request message indicating preferred resource blocks, where each resource block may be defined by a time and a frequency. The UE may receive a confirmation message that may include a report regarding a set of resource blocks. The set of resource blocks may be from the preferred resource blocks included in the resource map request message. The UE may determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications and initiate the side-link communications using the determined resource blocks.

Abstract: This disclosure relates to techniques for dynamically adjusting a number of active receiver chains of a wireless device. Based on communication parameters exchanged with a base station, a device may determine a maximum number of receiver chains needed for data reception during one or more time periods. Such dynamic adjustment may enable power savings.

Abstract: A base station and mobile device (UE) may coordinate transmission of reference signals and reception of corresponding channel state information (CSI) reports. If a periodic reference signal is scheduled for transmission outside the on-duration period of the UE, even if the reference signal corresponds to a periodic CSI report scheduled to be transmitted by the UE during the on-duration period, the base station may not transmit the periodic reference signal, thereby allowing the UE not to prematurely exit a low-power state. The base station may instead transmit an aperiodic reference signal at a specified point in time later than the scheduled transmission of the periodic reference signal. The UE may receive the aperiodic reference signal and either transmit the periodic CSI report or an aperiodic CSI report in response, depending on how close to the start of the on-duration period the transmission of the periodic CSI report is scheduled.

Abstract: This disclosure relates to techniques for a wireless device to indicate a preferred bandwidth part and duty cycle in a cellular communication system. A wireless device and a cellular base station may establish a radio resource control connection. The wireless device may transmit an indication of a preferred bandwidth part, or a preferred communication duty cycle, or both, to the cellular base station. The cellular base station may select a bandwidth part, or communication duty cycle, or both, based at least in part on the indication provided by the wireless device, and may transmit an indication of the selected bandwidth part, communication duty cycle, or both, to the wireless device. The cellular base station and the wireless device may perform cellular communication using the selected bandwidth part, communication duty cycle, or both.
