Method and device for obtaining and indicating frequency point of cell center

Abstract

The embodiment of the invention provides a community center frequency acquisition and indication device and device. The acquisition method of community center frequency comprises following steps: receiving wireless frequency point channel number UARFCN in wireless access to UTRA corresponding to a first frequency point sent out by a reception base station and difference information used for indicating the frequency difference between the first frequency point and a second frequency point; utilizing the second frequency point as the community center frequency; and acquiring the second frequency point based on UARFCN and difference information. The community center frequency acquisition and indication device and device provided by the embodiment of the invention have following beneficial effects: information of the second frequency point is transmitted based on existing UARFCN corresponding to the first frequency point and the frequency difference between the first frequency point and the second frequency point such that the second frequency point can be used for indicating center frequencies of all communities in all frequency bands.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for obtaining and indicating a cell center frequency point. Background technique [0002] In the Third Generation Partnership Project (Third Generation Partnership Project, hereinafter referred to as 3GPP), the center frequency point of the cell that can be used by the user equipment corresponds to the absolute wireless frequency point channel number of the cell of the Universal Mobile Telecommunications System (Universal Mobile Telecommunications System Absolute Radio Frequency Channel Number, hereinafter referred to as UARFCN), the user equipment can obtain the frequency value of the center frequency point corresponding to the UARFCN through the UARFCN, so as to realize the detection of the cell corresponding to the center frequency point. [0003] Currently in 3GPP, the frequency value of the center frequency point corresponding to UAR...

Problems solved by technology

However, the interval between the center frequency points of each cell is not necessarily an integer multiple of 200KHz, and the existing UARFCN cannot indicate the center frequency points of all cells.

[0004] In addition, with the increase of newly allocated frequency bands, currently 3GPP does not define the corresponding UARFCN for the frequency points in these newly allocated frequency bands, so these newly allocated frequency bands cannot be used in 3GPP yet.
