Abstract

The invention discloses a method and system for coordinating and scheduling frequency band resources in a cellular network. The method comprises the following steps of: classifying user terminals into UE-CO (User Terminals to be Coordinated) and UE-NCO (User Terminals not to be Coordinated) according to the quality of a channel; dividing frequency band resources into a plurality of equal frequency bands, and determining the starting point of each frequency band; measuring the average value of receiving power RSRP (Reference Signal Receiving Power) of each sector in the periphery by using the UE-CO, determining the maximum interference source, and allocating the frequency band resources according to the maximum interference source; assuming that the maximum interference source of the UE-CO is eliminated, and calculating the rate gain value delta C increased by a user by a base station accessed to a cell; and when the rate gain value delta C is greater than a preset threshold, sending a request for coordinating interference to the base station in which the maximum interference source isby using the UE-CO, and simultaneously reporting the quantized delta C'. The invention can increase the throughput of users in the edges of a cell and the total throughput of the system by less data exchange, and is helpful for improving the effectivity and the justification of the system.

Description

technical field

[0001] The invention relates to the technical field of mobile communication, in particular to a method and system for coordinated scheduling of frequency band resources in a cellular network. Background technique

[0002] The modern wireless cellular network is an interference-limited system, especially for cell-edge users, the high-intensity interference makes the SINR very unsatisfactory, which greatly limits the user's performance. CoMP (Coordinated Multi-Point) coordinated scheduling technology emerged as the times require. Through dynamic information interaction and coordination between APs (Access Points, Access Points), the most reasonable resource allocation strategy and resource coordination strategy are made to minimize the number of APs. Mutual interference of edge users. Specifically, through decision-making negotiation to prohibit the use of part of the frequency resources or reduce the transmission power in some cells, to help users who are dee...
