Patent ID: 11811706

Abstract:
A base station may transmit, to a wireless device, first downlink control information (DCI) via a physical downlink control channel (PDCCH) of an active bandwidth part (BWP), of the wireless device, during a discontinuous reception (DRX) active time. The base station may switch to a first downlink BWP as the active BWP during the DRX active time. The base station may start, in response to the switching, a BWP inactivity timer of the first downlink BWP. The base station may transmit a second DCI via a PDCCH of the first downlink BWP. The base station may receive a packet via a transmission interval of periodic resources indicated by a configured grant. The base station may restart the BWP inactivity timer at a time based on the transmission interval. The base station may switch, in response to an expiration of the BWP inactivity timer, to a second downlink BWP as the active BWP during the DRX active time. The base station may transmit a third DCI via a PDCCH of the second downlink BWP.
