Patent ID: 10778318

Abstract:
A wireless device activates a first downlink bandwidth part (BWP) of a cell and a first uplink BWP of the cell. An active downlink BWP, identified with a second downlink BWP index, is switched from the first downlink BWP to a second downlink BWP. It is determined that the second downlink BWP is configured with one or more beam failure recovery (BFR) parameters. An active uplink BWP, identified with a second uplink BWP index that is the same as the second downlink BWP index, is switched, based on the determining, from the first uplink BWP to a second uplink BWP. The active downlink BWP is switched from the second downlink BWP to a third downlink BWP. Based on a determination that the third downlink BWP is not configured with one or more BFR parameters, the second uplink BWP is kept as the active uplink BWP.
