Scheduling and data transmission method

Abstract

The invention discloses a scheduling and data transmission method, which performs more careful selection on edge users according to a channel quality threshold and channel quality of the edge users, does not perform combined treatment on the edge users with the channel quality smaller than the channel quality threshold, and again selects users with a second tall scheduling priority level in users to be scheduled in a base station to be possible users to be scheduled. The scheduling and data transmission method can improve neighborhood average frequency spectrum efficiency and neighborhood edge frequency spectrum efficiency.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a scheduling and data transmission method. Background technique [0002] In the wireless communication system, take the downlink communication system as an example, because the cell edge user is far away from the base station, the power received by the base station is relatively small, and at the same time, the interference from the neighboring cell base station is relatively large, so the channel quality is poor , resulting in lower throughput. With the development of new technologies and services in wireless communication, the requirements for channel quality and throughput of edge users are getting higher and higher. [0003] In the technical discussion process of LTE-Advanced, a method of using geographically separated points for coordinated transmission or reception is proposed, which is called Coordinated Multi-Point (CoMP) technology by 3GPP. CoMP technology concentra...

Problems solved by technology

[0006] However, there are certain defects in the scheduling and data transmission methods in the prior art: there are some edge users with poor channel quality, even if joint processing is performed on such edge users, the performance cannot be significantly improved, and instead the CoMP Operation concentrates the resources of all base stations, resulting in a decrease in the average spectral efficiency of the cell and the spectral efficiency of the cell edge

[0007] At the same time, when the channel quality of the user is improved, the throughput of the user may be improved due to the joint processing of the user, thereby reducing the scheduling priority factor value of the user, so that the edge user has a lower channel quality. When it gets better, it won't get joint treatment
