Adjacent sector data coordinated sending method

Abstract

The invention provides a method for coordinately sending data in adjacent sectors. The method comprises the following steps: defining threshold values of an RSRP (Reference Signal Received Power) value and an SINR (Signal to Interference plus Noise Ratio) value received by a terminal at first, independently scheduling a terminal service by a main cell base station if the received values of the terminal are higher than the threshold values, coordinately scheduling the terminal service by the main cell base station and an adjacent base station if the received values of the terminal are lower than the threshold values, copying data sent to the terminal by an EPC (Evolved Packet Core), respectively sending the data to the main cell base station and the adjacent base station, respectively sending the same data to the terminal simultaneously by the main cell base station and the adjacent base station, and demodulating the same data sent by the main cell base station and the adjacent base station in an MIMO (Multiple Input Multiple Output) manner by the terminal. According to the method in the embodiment of the invention, interference information in an adjacent area is converted into useful signals; the receiving quality of cell edge users is increased; the utilization rate of the transmitting power of the base station is increased; the workable bandwidth of the cell edge users is expanded from a partial bandwidth to a fully available bandwidth; and thus, the throughput rate of the cell edge users can be effectively increased.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a method for coordinating and sending adjacent sector data. Background technique [0002] LTE (Long Term Evoution, Long Term Evolution) network coverage generally uses the same frequency, but using the same frequency will cause interference between sectors. In order to eliminate LTE network interference, related technologies mainly divide the coverage area into a central area and an edge area. The central area uses all frequency bands, and the edge area uses narrower frequency bands. Adjacent cells use different frequency bands in the edge area to reduce inter-cell interference. , this method is called Cell Interference Coordination (ICIC), but ICIC avoids interference by limiting the use of spectrum in the edge area to significantly reduce the throughput of cell edge users. [0003] Another common method for avoiding LTE network interference is to control sector transmit po...
