Patent ID: 8363566

Claim:
A method for sending a scheduling request (SR) signal, which is used for a user equipment (UE) in a long term evolution system to send an uplink signal to a base station, comprising: the UE determining a radio frame and a subframe for sending the SR signal: if a time length of a radio frame is less than an SR periodicity, a sending frame and a subframe for the SR signal are determined after shifting an SR subframe offset from a starting subframe of a first radio frame of multiple consecutive radio frames which have a total time length equal to the SR periodicity; if a time length of a radio frame is equal to or greater than the SR periodicity, each radio frame is determined as the sending frame for the SR signal, and if a time length of a radio frame is equal to the SR periodicity, a subframe of the sending frame is determined after shifting the SR subframe offset from the starting subframe of the sending frame, and if a time length of a radio frame is greater than the SR periodicity, a subframe of the sending frame is determined after shifting the SR subframe offset from the starting subframe of a radio half-frame; and the UE sending the SR signal to the base station in the determined subframe of the sending frame.
