The invention discloses a channel condition representation-based dynamic spectrum sharing method and system. The method comprises the following steps: modeling the channel conditions of a primary system and a secondary system respectively according to service features and a scheduling algorithm; establishing a unified model for a dynamic spectrum sharing system according to the respective models of the primary and secondary systems; and obtaining the communication performance of a secondary user according to the unified model, and determining the access strategy of the secondary user according to the communication performance of the secondary user. The invention also discloses the channel condition representation-based dynamic spectrum sharing system. By the scheme of the invention, more practicable condition assumptions can be provided for performance analysis and emulation of the dynamic spectrum sharing system, so that the performance analysis and emulation of the dynamic spectrum sharing system are more accurate, and the channel condition representation-based dynamic spectrum sharing method and system provided by the invention are beneficial to switching the secondary user to a channel with relatively small switching occurrence probability in advance, thereby reducing the collision and switch time delay.
Description
technical field [0001] The invention relates to a dynamic spectrum sharing technology in a wireless communication system, in particular to a dynamic spectrum sharing method and system based on channel state representation. Background technique [0002] With the rapid development of wireless communication services, wireless spectrum resources become increasingly tight. However, according to existing measurement data, the existing spectrum allocation system based on fixed spectrum allocation has very low resource utilization. In order to improve the utilization rate of the existing spectrum, the concept of dynamic spectrum sharing came into being. [0003] The communication system that has the right to use the spectrum is called the primary system, and the communication system that does not have the right to use the spectrum and can only use the idle spectrum for communication in the form of "opportunistic spectrum access" is called the secondary system. The current dynamic ...
