Uplink wireless cooperative multipoint transmission communication network and transmission method thereof

Abstract

The invention discloses an uplink wireless cooperative multipoint transmission communication network and a transmission method thereof. The communication network comprises a plurality of base stations and a plurality of cooperative receiving points, wherein the cooperative receiving points participate in cooperative transmission in a mode of certain base station privacy or adjacent base station public control. A master base station establishes a cooperation relationship with the cooperative receiving points belonging to a current cell and determines the cooperative receiving points which participate in cooperative receiving when the cooperative receiving is needed; the cooperative receiving points which participates in cooperative receiving receives data of a user terminal at the corresponding idle time slot after receiving a data receiving trigger signal of the master base station, and transmits the received data of the user terminal or the signal to the master base station; and the master base station carries out combined detection for demodulating uplink data according to the data or signal transmitted by the cooperative receiving points which participate in the cooperative receiving together with the data received by the master base station. Due to application of the uplink wireless cooperative multipoint transmission communication network and the transmission method thereof, larger uplink throughput can be obtained under the condition of not changing the layout of the existing site, and pay expenses to an X2 port and occupancy to wireless resources of adjacent regions cannot be caused.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to an uplink wireless coordinated multi-point transmission communication network and a transmission method thereof. Background technique [0002] Cooperative Multi-Point transmission (CoMP) is a technical means to improve the throughput of cell edge users and thereby improve the throughput of the entire network. The traditional coordinated multi-point reception technology is to perform cooperative reception between the main cell (also called "serving cell") and the cooperative cell. It is sent to the main cell through the X2 port, and the main cell performs joint detection and combination. [0003] The above-mentioned CoMP uplink data transmission scheme requires a large amount of data interaction between the main cell and the cooperative cell, which puts a lot of pressure on the transmission of the X2 interface, and the cross-cell joint detection and combina...
