Problems solved by technology

However, for border cell users, bandwidth resources are inherently scarce and unstable, and the above-mentioned excessive amount of transmitted information will greatly increase the overhead of the reverse link, and in severe cases will lead to a decrease in actual system capacity

Abstract

The invention relates to a distributed transmission scheduling method based on a capacity increase. By reporting the channel information a mobile terminal with a signal-to-noise ratio higher than a response threshold value in a service-providing cell and reporting the channel information of a mobile terminal with an interference level lower than a preset value in a service-assisting cell, the method may greatly decrease the amount of information transmitted in reverse direction, increases system capacity, and improves the efficiency of a boundary cell user participating in distributed transmission when bandwidth resources are insufficient and unstable.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a distributed transmission scheduling method based on capacity enhancement. Background technique [0002] With the sharp increase in the number of mobile communication users and the rapid rise of wireless broadband services (such as multimedia services), it is expected that mobile communication systems can provide higher data transmission rates (above 100Mbps) and higher spectral efficiency (above 10bps / Hz) ). [0003] The multiple-input single-output system is a smart antenna technology that configures multiple antennas at the transmitting end and a single antenna at the receiving end. It is an effective means to improve spectrum efficiency. However, in the actual application of multiple-input single-output systems, the interference from the same cell and adjacent cells will greatly affect the system performance, so interference needs to be suppressed. At the same time, us...
