A wireless device receives configuration parameters for a first logical channel indicating a first mapping restriction of the first logical channel to at least one first radio resource type of a plurality of radio resource types. The at least one first radio resource type indicates one of a licensed radio resource type or an unlicensed radio resource type. An uplink grant indicating radio resources of a radio resource type in the plurality of radio resource types is received. Based a determination that the radio resource type of the uplink grant is one of the at least one first radio resource type based on the first mapping restriction, a first buffer status report (BSR) retransmission timer for triggering a BSR indicating an amount of data comprising data of a buffer of the first logical channel is restarted. A BSR transmission is triggered in response to the first BSR retransmission timer expiring.
