Abstract
The present disclosure discloses a method for detecting a signal in an LTE system, the method includes that: an eNodeB calculates a signal power Ps and a noise power Pn according to the data part of a signal sent by a UE on a channel resource, a Constant Amplitude Zero Auto-Correlation (CAZAC) sequence, an orthogonal sequence W distributed to the UE, and a sequence Wn orthogonal to the W stored by itself; and the ratio of Ps to Pn is compared with a predetermined threshold and a corresponding detection result is determined according to the comparison result. The present disclosure further discloses a device for detecting a signal in an LTE system. The method and device can be used for accurately, simply and easily detecting whether the UE initiates a scheduling request or whether DTX occurs to the UE, so that the eNodeB can determine to whether to continuously send a subsequent message or whether to resend the message which the UE has failed to receive, thereby improving the scheduling performance of the eNodeB.
