| 摘要 | A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station is provided. The user equipment comprises a buffer. Directly or indirectly responsive to receiving data into the buffer to be transmitted to the base station, the user equipment generates a scheduling request trigger. The scheduling request trigger is configured to trigger the sending of a scheduling request to the base station if the trigger is pending at the next scheduling request opportunity, and to remain pending until it is cancelled. The user equipment cancels the pending scheduling request trigger when the data is accounted for in a buffer status report, which reports the size of the buffer to the base station, or when the data is included directly in a scheduled uplink data transmission whichever occurs first. | ||

| 主权项 | 1. A method in a user equipment for requesting that a base station schedule the user equipment for an uplink data transmission to the base station, the user equipment comprising a buffer, the method comprising: receiving data into said buffer that is to be transmitted to the base station via a scheduled uplink data transmission; and sending a scheduling request to the base station when a next scheduling request opportunity occurs, only if the buffer contains data that has both not been accounted for in a buffer status report, which reports the size of said buffer to the base station, and will not be included directly in a currently scheduled uplink data transmission. | ||
