An SR is triggered in response to uplink resources not being available for transmission of a triggered BSR, where the triggered BSR is in response to uplink data becoming available for one of the first logical channel or the second logical channel. The SR is transmitted via an SR resource that corresponds to a logical channel that triggered the BSR. The base station receives an uplink grant for transmission of transport block(s) in a transmission duration that corresponds to the one of the first logical channel or the second logical channel. ## Claims ### Claim 1 A method comprising: receiving, by a wireless device from a base station, one or more messages indicating: a first scheduling request (SR) resource, of the base station, corresponding to a first logical channel, the first logical channel corresponding to one or more first transmission durations up to a first value;
