Abstract

The invention discloses dynamic resource allocation method and equipment of a multi-cell wireless communication system. In the invention, a controller receives channel state information, intercell interference information and flow demand information; global optimization is carried out on sub-channel allocation according to the received information so as to ensure that uplink throughput and downlink throughput of the system realize maximization; a sub-channel allocation result is sent to a base station, the base station is used for designating all time slots of all frames by using a proportional fair scheduling algorithm aiming at all service varieties according to the received sub-channel allocation result; and results designated by the time slots are sent to a mobile station. According to the technical scheme of the invention, by considering factors of a QoS requirement of a user, the intercell interference and the uplink flow requirement and the like, the invention ensures that each user can obtain broadband resources matched with the flow requirement and the QoS requirement, and improves the uplink and the downlink throughput of the system.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a dynamic resource allocation method and equipment for a multi-cell wireless communication system. Background technique [0002] Currently, the demand for mobile voice and data services in next-generation wireless communication systems is increasing. Ensuring the quality of service (QoS) requirements of each user while increasing the user capacity of the system is the main issue that needs to be considered when building these systems. [0003] The conventional cellular communication system has a relatively simple structure, but cannot effectively utilize wireless resources. In the cellular communication system, the frequency reuse technology is generally used, that is, the same frequency is reused to improve the system capacity and spectrum efficiency, and this frequency reuse technology is generally static. figure 1 A prior art cellular communication system with a r...
