Embodiment Construction

[0028] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0029] As mentioned earlier, interference coordination techniques complicate the spectrum resources available within the base station coverage. In a co-frequency networking system, within the system bandwidth, considering the factor of interference coordination, the spectrum resources available for base station i Ω i can be divided into three parts: resources shared with neighboring cells (hereinafter referred to as shared resources), resources orthogonal to adjacent cells (hereinafter referred to as orthogonal resources) and central resources

[0030] Within the coverage of the same base station, the relationship among shared resources, orthogonal resources and central resources is: The relationship between shared resources, orthogonal resources and c...

Abstract

The invention discloses a dispatching method in a relay network, which comprises the following steps of: allocating a relay link resource to relay equipment by taking the relay equipment as a terminal of a base station; when the allocated relay link resource is a shared resource, dispatching the resource by using a centralized dispatching mode; when the allocated relay link resource is an orthogonal resource, receiving the shared resource occupancy rate which is reported by user equipment (UE); if the shared resource occupancy rate is less than a preset threshold, dispatching the resource by using a distributed dispatching mode and taking the shared resource as the access link resource; and otherwise, dispatching the resource by using the centralized dispatching mode. The method can be suitable for a complex wireless environment and a resource allocation mode after using the interference coordination technology; and a proper dispatching mode is chosen according to different scenes so as to reduce the expenditure of the signaling dispatching while ensuring interference suppression.

Description

technical field [0001] The invention relates to a resource scheduling technology in a wireless communication system, in particular to a scheduling method in a relay network. Background technique [0002] In the follow-up mobile communication system of 3G, as the user's demand for system bandwidth increases, the frequency band used by the mobile communication system has to develop to a higher frequency band, such as using a frequency band exceeding 3GHz, etc. At this time, radio wave transmission The reduction of the distance leads to the reduction of the coverage of the base station; at the same time, the increase of the user capacity makes the researchers have to find a way to expand the network capacity based on the architecture of the cellular network, so that the introduction of relay equipment (that is, the base station and user The transmission of wireless signals between wireless devices is relayed by relay equipment) has gradually attracted more and more attention in...
