  • Downlink control channel skipping
    Patent number: 11818733
    Abstract: A wireless device receives configuration parameters indicating duration values for skipping physical downlink control channel (PDCCH) monitoring on a bandwidth part (BWP). The duration values are from: first values in response to the BWP having a first subcarrier spacing (SCS) and second values in response to the BWP having a second SCS, with each value of the second values being equal to multiplication of a respective value, of the first values, and a same granularity value. The wireless device may receive a downlink control information (DCI) indicating skipping PDCCH monitoring on the BWP for a time duration based on a duration value of the duration values. The wireless device may skip monitoring the PDCCH on the BWP for the time duration, based on the DCI.

  • Method and apparatus for designing broadcast channel for NR in wireless communication system
    Patent number: 11818703
    Abstract: According to the present invention, a common control signal via a group common control channel (GCCC) for a new radio access technology (NR) is defined. A user equipment (UE) receives the common control signal from a network via GCCC. The common control signal is for all UEs or a group of UEs in a cell. The UE handles the priority of the common control signal compared to other signals. For example, the priority of the common control signal may be higher than a semi-static UE-specifically configured configuration, and may be lower than a cell-commonly or group-commonly configured configuration.
