Embodiment Construction

[0019] A method and device for allocating distributed spectrum resources provided by embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] Such as figure 1 As shown, a distributed spectrum resource allocation method provided by an embodiment of the present invention, the method includes:

[0021] 101: The receiving end of the distributed system receives a request message, and the request message carries a spectrum resource occupancy list of the sending end and parameters of services to be transmitted; wherein, the specific representation of the spectrum resource occupancy list can be in bit The map (bitmap) represents a spectrum resource occupancy list, or a list of bandwidths and central frequency points, and the number of bandwidths, or a column of bandwidths and starting frequency points, and the number of bandwidths, and so on. The parameters of the service to be transmitted include: the size of the se...

Abstract

The invention discloses a method and a device allocating distribution type spectrum resource, which relates to the technical field of radio. The invention aims to solve the problem that the distribution type network in the prior art can not realize dynamic allocation of discontinuous spectrum. The method for allocating distribution type spectrum resource comprises the following steps of: receiving request information, which carries a spectrum resource occupying condition list and parameters of the service to be transmitted at the sending end; acquiring an idle spectrum resource collection available for the service to be transmitted according to the received spectrum resource occupying condition list and the local spectrum resource occupying condition list, wherein the idle spectrum resource collection is the idle spectrum resource collection shared by the sending end and the transmitting end; and allocating at least one section of spectrum resource in the idle spectrum resource collection available for the service to be transmitted to the service to be transmitted according to the parameters of the service to be transmitted.

Description

technical field [0001] The present invention relates to the field of radio technology, in particular to a method and device for allocating distributed frequency spectrum resources. Background technique [0002] In a traditional radio communication system, its spectrum resource is a pre-allocated fixed resource. The radio communication system performs service transmission through the pre-allocated spectrum resource. Under this mechanism of fixed frequency spectrum allocation, even if the system does not use the frequency spectrum resource, other systems must not use the frequency spectrum resource, so that the wireless frequency spectrum utilization rate in the prior art is low. [0003] In order to solve the problem of low wireless spectrum utilization in the traditional radio communication system, cognitive radio technology is proposed. The principle of the cognitive radio technology is that the equipment in the cognitive radio system has the ability to detect spectrum oc...
