Abstract

The invention provides a method and device for realizing transmission of a cell reference signal for a base station, and the base station. The method comprises the following steps of: obtaining the power of the cell reference signal and the transmitting power of a remote radio unit RRU channel; according to the power of the cell reference signal and the transmitting power of the RRU channel, obtaining a rate of the power of the cell reference signal to the transmitting power of the RRU channel; and, generating a time-domain cell reference signal according to a communication protocol and the rate, and transmitting the cell reference signal. By means of the method disclosed by the invention, the base station can accurately transmit the cell reference signal.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, a device and a base station for realizing cell reference signal transmission by a base station. Background technique [0002] At present, Long Term Evolution (3GPP LTE, Long Term Evolution,) is the current mainstream communication method. The uplink and downlink of 3GPP LTE adopt single-carrier OFDMA and OFDMA respectively. This orthogonal frequency division multiplexing method can greatly improve spectrum utilization, is suitable for high-speed data transmission services, and also supports flexible configuration of various bandwidths. [0003] LTE downlink physical layer channels include Physical Downlink Shared Channel (PDSCH, Physical DownlinkShared Channel), Physical Control Format Indicator Channel (PCFICH, Physical Control Format Indicator Channel), Physical Downlink Control Channel (PDCCH, Physical Downlink ControlChannel), etc. Physical s...
