A SENDING METHOD AND DEVICE FOR SCHEDULING REQUEST (SR) SIGNAL

摘要

A sending method and device for scheduling request (SR) signal is used for UE to send an uplink signal to a base station in the long term evolution (LTE) system. The method involves that:  after a starting sub-frame of the first radio frame in several consecutive radio frames whose total time length is equal to the SR cycle is moved for a SR sub-frame deviation, a sending frame and sub-frame for the SR signal is confirmed, when the time length of a radio frame is less than the SR cycle; each radio frame is confirmed as the sending frame of the SR signal, when the time length of the radio frame is equal to or greater than SR cycle, and: a starting sub-frame of the sending frame is moved for a SR sub-frame deviation and located to the sub-frame of the sending frame when the time length of the radio frame time length is equal to the SR cycle; a starting sub-frame of a radio semi-frame is moved for a SR sub-frame deviation and located to the sub-frame of the sending frame when the time length of the radio frame is greater than the SR cycle; the SR signal is transmitted by UE to a base station on the sub-frame of the confirmed sending frame.
