Abstract

A wireless device receives one or more RRC messages comprising configuration parameters of a cell. The configuration parameters indicate uplink BWPs of an uplink carrier of the cell. The uplink BWPs comprise a first uplink BWP and a second uplink BWP. The configuration parameters further indicate a sidelink BWP of the uplink carrier of the cell. A numerology of the second uplink BWP is different than a numerology of the sidelink BWP. The wireless device activates the first uplink BWP. The wireless device activates the sidelink BWP. The wireless device switches from the first uplink BWP to the second uplink BWP as an active uplink BWP. The wireless device deactivates, based on the switch, the sidelink BWP.

Dependent claims

A method comprising:

receiving, by a wireless device, configuration parameters indicating a first value for a bandwidth part (BWP) inactivity timer of a downlink BWP of a cell;
receiving, via the downlink BWP, first control information indicating a downlink grant on the downlink BWP;
starting or restarting, based on the first control information indicating the downlink grant, the BWP inactivity timer with the first value;
receiving, via the downlink BWP, second control information indicating a sidelink grant on a sidelink BWP of the cell;
and
stopping, based on the second control information indicating the sidelink grant, the BWP inactivity timer at a second value.
