Dispatching method, device and system of wireless cellular network

Abstract

The embodiment of the invention discloses dispatching method, device and system of a wireless cellular network, which relate to the field of communication and can realize high-performance dispatching in a cognitive wireless cellular system. The dispatching method comprises the following steps of: determining resource allocation target information by a relay station according to obtained frequency spectrum perception information and channel quality information, and sending the resource allocation target information to a base station; allocating network resources to the relay station and notifying an allocation result to the relay station by the base station according to the obtained frequency spectrum perception information and channel quality information as well as the resource allocation target information sent by the relay station, and sending data to the relay station according to the allocation result; allocating resources to an accessed mobile terminal and notifying the allocation result to the mobile terminal by the relay station according to the data sent by the base station, the frequency spectrum perception information and the channel quality information, and sending data to the mobile terminal according to the allocation result.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless cellular network scheduling method, device and system. Background technique [0002] In order to improve spectrum utilization, the idea of ​​cognitive radio (Cognitive Radio, CR) is proposed. This idea divides the wireless system into primary system (Primary System) and secondary system (Secondary System). [0003] Among them, the primary system is usually an existing wireless communication system, which is composed of primary users (Primary User, PU) and primary base station (Primary Base Station). System interference. [0004] The secondary system may consist of only secondary users (Secondary User, SU), or may consist of secondary users and secondary base stations. The secondary system has no legal spectrum authorization, and can only use the idle main system frequency band for communication, and actively withdraws when it detects that the primary user starts to...

Problems solved by technology

[0007] However, since the above two algorithms are only suitable for point-to-point communication, they cannot be applied to cellular systems, and it is currently impossible to achieve high-performance scheduling in cognitive radio cellular systems
