Problems solved by technology

[0006] In the existing distributed antenna mobile communication system, generally, each cell simultaneously transmits the same downlink signal on all wireless signal processing units. In addition, the uplink signal is processed by all wireless signal processing units in the cell. It can be seen that in the existing distributed antenna mobile communication system, the uplink receiving and processing of the data stream is almost unchanged, while in the multi-antenna system, the effective information of a user is generally only carried in some Therefore, if a transmitting antenna does not carry the effective information of the user, the data on the antenna received at the receiving end is noise relative to the user information
At present, there is no particularly effective method for distributing data streams on multiple antenna arrays. The downlink user data transmission method in the existing distributed antenna mobile communication system has always been an important research direction for wireless communication technicians.

Abstract

A method for sending downlink user data is provided, which is used in distributed antenna mobile communication system. The method includes: Collecting all antennae signals; Determining effective antennae to bear every user's data according to the antennae signals; Allocating user's downlink data to the corresponding effective antennae and then sending them.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for sending downlink user data and a corresponding distributed antenna mobile communication system. Background technique [0002] In the past ten years, with the rapid development of mobile communication, the available wireless spectrum resources have been continuously moved up, the attenuation of wireless signals has become more and more serious, and the radius of cells has been continuously reduced. The continuous shrinking of the cell radius means that the base station density increases and the cost of network construction increases. At the same time, frequent handovers result in waste of air resources and lower spectrum efficiency. [0003] In the traditional smart antenna system, multiple antennas are placed on the base station, and multiple antennas are also placed on the mobile station. A communication link is formed between the base station and the mo...
