Problems solved by technology

[0009] At present, a new carrier type (New Carrier Type, NCT) is proposed in the LTE Rel-11 standard. Since the existing RSRP measurement method is to detect neighboring cells based on the design structure of the PSS and SSS corresponding to the traditional carrier type The PSS and SSS corresponding to the new carrier type and the PSS and SSS corresponding to the traditional carrier type have different design structures, so the existing RSRP measurement method can only detect adjacent cells using the traditional carrier type

Abstract

The invention discloses a method and device for measuring reference signal received power. The method comprises the steps that measurement configuration information sent by an eNB is received, wherein the measurement configuration information carries a work frequency point and a measurement reporting condition; a PSS and an SSS of first-kind neighboring cells are detected in a preset time window on the work frequency point, and the RSRP value of each first-kind neighboring cell is measured according to the detected PSS and the detected SSS; when it is determined that RSRP measurement needs to be conducted on second-kind neighboring cells, a PSS and an SSS of the second-kind neighboring cells are detected in the time window on the work frequency point, and the RSRP value of each second-kind neighboring cell is measured according to the detected PSS and the detected SSS; the RSRP values, meeting the measurement reporting condition, of the first-kind neighboring cells and the RSRP values, meeting the measurement reporting condition, of the second-kind neighboring cells are reported to the eNB. Compared with the prior art, the method and device for measuring the reference signal received power has the advantages that RSRP measurement can be conducted on both a neighboring cell and a traditional carrier wave type and a neighboring cell with a new carrier wave type.

Description

technical field [0001] The present application relates to mobile communication technology, in particular to a method and device for measuring received power of a reference signal. Background technique [0002] Reference Signal Received Power (RSRP) refers to all resource elements ( Resource Element, RE) the average value of the received signal power. It is one of the important bases for user equipment (UE) to perform cell reselection and handover, and its accuracy directly determines the accuracy of UE's cell reselection and handover, thereby affecting the performance of the entire system. [0003] In the existing Long Term Evolution (LTE) system, the evolved base station (Evolved Node B, eNB) will send measurement configuration information to the UE in the connected state, and judge according to the received measurement results reported by the UE Whether the UE performs handover. Specifically, the measurement quantities triggered when the eNB sends measurement configurat...
