Method for transmitting down user data and distributed antennae mobile communication system

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...
