Abstract

A wireless device receives configuration parameters indicating a mapping restriction, of a plurality of mapping restrictions, of a logical channel to one or more radio resource types of a plurality of radio resource types. A buffer status report is triggered based on uplink data becoming available. An uplink grant indicating radio resources of a radio resource type of the plurality of radio resource types is received. A scheduling request is triggered in response to: the triggering the buffer status report; and the radio resource type not being of at least one first radio resource type, of the plurality of radio resource types, determined based on the plurality of mapping restrictions.
