Description

Reference signal measurement method, user equipment and network equipment

The present application is a divisional application of patent applications filed on 9.6.2014.2014.under the name of "reference signal measurement method, user equipment and network equipment" with the application number of 201480000326.2.

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a reference signal measurement method, a user equipment, and a network device.

Background

Currently, CRS (Cell Reference Signal) measurement in LTE (Long Term Evolution) refers to measurement of a Cell common Reference Signal. In order to obtain the position where the CRS appears, the UE needs to first detect a synchronization channel of the Cell, define a frame boundary according to the synchronization channel, and then determine the position where the CRS appears, including a time domain position and a frequency domain position, according to frame boundary information and a Cell PCI (Physical Cell Identifier). The sending positions of the CRSs of the LTE cell are fixed, and a UE (User Equipment) may determine the PCI of the cell according to a synchronization channel, and after determining the PCI, the time domain position and the frequency domain position of the CRS are also determined.

The prior art has at least the following problems: the CRS may be transmitted in either a licensed or unlicensed spectrum. The unlicensed spectrum refers to a common spectrum which can be used by any organization or person, but when the unlicensed spectrum is used, the rule of listening before transmitting is followed, that is, only when the spectrum is sensed to be idle, the CRS signal can be transmitted on the unlicensed spectrum, so that the CRS signal of some cells is discontinuous. In this case, when the CRS signal of the cell is not continuous, even if the UE knows the PCI, the CRS signal corresponding to the PCI may not be transmitted at the time domain position and the frequency domain position of the CRS corresponding to the UE. Inaccurate measurements may occur if the UE performs CRS measurements for these locations and processes the measurements.
