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 capacity-enhancing distributed transmission scheduling system of the present invention reports channel information to mobile terminals whose signal-to-noise ratio is higher than the response threshold in the service-providing cell, and reports channel information to mobile terminals whose interference level is lower than a predetermined value in the service-assisting cell. Information reporting can greatly reduce the amount of reversely transmitted information when bandwidth resources are scarce and unstable, improve system capacity, and increase the efficiency of border cell users participating in distributed transmission.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a distributed transmission scheduling system based on capacity improvement. 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...
