Abstract: This disclosure relates to techniques for supporting message mapping via time and/or frequency indexing. For example, these techniques may be applied to device-to-device wireless communication. For example, device to device discovery may use message mapping via frequency indexing. A portion of the payload of a message, such as a discovery message, may be offloaded to a frequency and/or time index. A receiving device may determine the offloaded portion of the payload based on the frequency and/or time (e.g., subcarrier and/or slot) used to transmit the message.

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: A communication terminal is described comprising a first transceiver configured for communication according to a first radio access technology and a second transceiver configured for communication according to a second radio access technology. The second transceiver is configured to determine whether a frequency range is occupied by a transmission according to the second radio access technology and to notify the first transceiver whether the frequency range is occupied by a transmission according to the second radio access technology. The first transceiver is configured to receive signals transmitted in the frequency range based on the notification from the second transceiver.

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 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: A method is disclosed where a user equipment (“UE”) is operating in a carrier aggregation mode and connected to a first cell operating on a licensed band and a second cell operating on an unlicensed band. The method may include the UE performing a carrier sensing operation on the unlicensed band, determining, from the carrier sensing operation, a duration that the unlicensed band will be occupied, refraining from transmitting data to the second cell on the unlicensed band for the duration that the unlicensed band will be occupied and setting a transmitter in communication with the second cell to a low power mode for the duration that the unlicensed band will be occupied.
