  • Channel access priority for NR-U data bearers
    Patent number: 11304086
    Abstract: Wireless communication devices, systems, and methods related to mechanisms to aid a user equipment in determining the channel access priority (CAPC) to use for a data radio bearer (DRB) on the response link, such as uplink (UL), that includes multiple quality of service (QoS) flows for an UL transmission (such as for a configured grant UL transmission). The UE may receive a plurality of QoS flows in a common DRB from a base station. The UE may apply a rule to select a CAPC to apply for all QoS flows in the common DRB on an UL transmission. This rule may alternatively include the base station making the selection of the CAPC to apply and informing the UE of the selected CAPC for implementation. The UE may then apply the selected CAPC to the UL transmission.

  • Controlling device modem scan duty cycle based on device sensor or wireless data
    Patent number: 11304141
    Abstract: Various different types of computing devices include a modem that allows the computing device to communicate wirelessly with other devices using various different radio access technologies (RATs). During operation of the computing device, the modem scans for a cell to connect to using a particular RAT, and once found connects to the cell. The computing device also includes a modem scan management system that manages the modem scanning for a cell to connect to, controlling the modem's scanning for a cell to connect to, such as stopping scanning using a particular RAT or reducing the frequency of the scans until movement of the computing device by a significant amount is detected.
