A user equipment comprising: a receiver which, in operation, receives from a radio base station configuration information used to configure a second trigger condition, processing circuitry, coupled to the receiver, which, in operation, determines whether a first trigger condition is fulfilled, the first trigger condition requiring a buffer status report, BSR, being triggered due to data becoming available in a transmission buffer, and determines whether the second trigger condition is fulfilled when the first trigger condition is fulfilled, the second trigger condition requiring a timer related to the data of the transmission buffer being expired, wherein the timer is started when the first trigger condition is fulfilled and triggering of a scheduling request transmission is postponed until the timer is expired, and the timer is not started when the first trigger condition is fulfilled for a logical channel for which the timer of the second trigger condition is not configured, and a transmitter, coupled to the processing circuitry, which, in operation, triggers transmission of a scheduling request to the radio base station requesting uplink resources when defined conditions are fulfilled including the first and second trigger conditions being fulfilled. a receiver which, in operation, receives from a radio base station configuration information used to configure a second trigger condition, processing circuitry, coupled to the receiver, which, in operation, determines whether a first trigger condition is fulfilled, the first trigger condition requiring a buffer status report, BSR, being triggered due to data becoming available in a transmission buffer, and determines whether the second trigger condition is fulfilled when the first trigger condition is fulfilled, the second trigger condition requiring a timer related to the data of the transmission buffer being expired, wherein the timer is started when the first trigger condition is fulfilled and triggering of a scheduling request transmission is postponed until the timer is expired, and the timer is not started when the first trigger condition is fulfilled for a logical channel for which the timer of the second trigger condition is not configured, and determines whether a first trigger condition is fulfilled, the first trigger condition requiring a buffer status report, BSR, being triggered due to data becoming available in a transmission buffer, and determines whether the second trigger condition is fulfilled when the first trigger condition is fulfilled, the second trigger condition requiring a timer related to the data of the transmission buffer being expired, wherein the timer is started when the first trigger condition is fulfilled and triggering of a scheduling request transmission is postponed until the timer is expired, and the timer is not started when the first trigger condition is fulfilled for a logical channel for which the timer of the second trigger condition is not configured, and a transmitter, coupled to the processing circuitry, which, in operation, triggers transmission of a scheduling request to the radio base station requesting uplink resources when defined conditions are fulfilled including the first and second trigger conditions being fulfilled.
