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.

Abstract: This disclosure relates to techniques for opportunistically depowering receiver chains of a wireless device. Based on control information, a device may determine whether the current number of active receiver chains can be reduced while maintaining a target achievable code rate for a period of data reception associated with the control information. Additionally, the device may generate and use a lookup table to determine whether to depower receiver chains, and which receiver chains to depower.

Abstract: Apparatuses, systems, and methods for a wireless device to perform user equipment (UE) initiated beam management procedures with a base station or gNB. A wireless device in communication with a 5G base station may detect degradation in the pair of transmit and receive beams between the gNB and the device. The device may select a preferred beam management procedure and indicate the preference to the gNB.

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: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

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.
