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 establish 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 simultaneous uplink activity for multiple RATs in the same carrier using multiplexing at a layer above the physical layer. The wireless device may establish wireless links with first and second base stations, respectively, according to first and second radio access technologies (RATs), respectively. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether inter-RAT uplink coexistence in the same frequency band is enabled. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth by multiplexing uplink data for the first RAT and uplink data for the second RAT at a layer above the physical layer.

Abstract: A device and method for power saving between a scheduling request and a grant. A user equipment (UE) establishes a connection to a network, the UE and the network may be configured with a Connected Discontinuous Reception (C-DRX) functionality, the C-DRX functionality including a cycle with at least one onDuration. The UE transmits, during a first subframe a scheduling request (SR) to the network, the SR corresponds to data that is to be transmitted by the UE. The UE determines a second subframe for the UE to enter an active mode of processing for a reception of a grant, the second subframe is subsequent to the first subframe and prior to a next onDuration. The UE initiates an active mode of processing for the reception of the grant during the second subframe.

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: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for Fifth Generation New Radio (5G NR) frequency range two (FR2) based communications beam management. The UE may configure, via communications with a base station, serving the UE, a group ID for PUCCH resources within a group of PUCCHs, e.g., for FR2 based communications. The UE may receive, from the base station, an update to one or more PUCCH resources within the group of PUCCHs via a medium access control (MAC) control element (CE) that may include one of a resource ID indicating an update to a PUCCH resource or the group ID to update the group of PUCCH resources. The UE may update, based on the MAC-CE, the one or more PUCCH resources within the group of PUCCHs.
