Embodiment 1

[0079] Such as image 3 As shown, taking the allocation of reusable sub-bands to user equipment after negotiation between macro base stations in LTE as an example, the method for allocating spectrum resources in the embodiment of the present invention will be described in detail. The method includes steps 301-step 309:

[0080] Step 301: When the base station A detects that the serving first user equipment needs to increase sub-frequency bands, if there is no idle sub-frequency band allocated to the first user equipment in the total spectrum resources, then obtain the first base station's frequency measured by the first user equipment Interference value of neighboring base stations.

[0081] Step 302: Base station A determines candidate sub-frequency bands according to the occupancy of the sub-frequency bands. The candidate sub-frequency bands do not include the sub-frequency bands occupied by neighboring base stations whose interference value is greater than the first threshold...

Embodiment 2

[0091] Such as Figure 4 As shown, taking the allocation of reusable sub-frequency bands to user equipment when the resource list is stored in femto as an example, the method for allocating spectrum resources in the embodiment of the present invention will be described in detail. The method includes steps 401-413:

[0092] Step 401: When the first femto detects that the serving user equipment m needs more sub-bands due to service requirements, it inquires whether there are free sub-bands in its own resource list, if so, executes step 402, and if not, executes Step 403.

[0093] In step 402, the first femto allocates an idle sub-band to user equipment m, and notifies the adjacent femto of the identity of the sub-band newly occupied, so that the adjacent femto can update the resource list.

[0094] Step 403: the first femto obtains the user equipment m and measures the RSRP of the adjacent femto.

[0095] Step 404: The first femto determines, according to the RSRPs of neighbor...

Abstract

The invention discloses a method for allocating frequency spectrum resource and a device thereof. The method comprises a step of obtaining the interference value of an adjacent base station measured by first user equipment when a sub band is needed to be added to the served first user equipment and if total spectrum resource has no idle sub band which is allocated to the first user equipment, a step of determining a candidate sub band according to the occupation of the sub band, wherein the candidate sub band does not comprise a sub band whose interference value is larger than a first threshold occupied by the adjacent base station and does not occupy a sub band occupied by the first base station, a step of sending same frequency resource multiplex application to the adjacent base station which occupies the candidate sub band, and a step of multiplexing the sub band and allocating the sub band to the first user equipment for use through the first base station for any candidate sub band in the same frequency resource multiplex application when the multiplexable responses of all the adjacent base stations which occupy the sub band are received, wherein the multiplexable responses comprise the identification of the sub band. According to the method, the utilization of spectrum resources can be improved.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for allocating frequency spectrum resources. Background technique [0002] With the development of wireless communication technology and the increase of users, spectrum resources become more and more tight. How to serve more users through limited spectrum resources is very important for communication systems. Spectrum resource reuse has made a certain contribution to solving the problem of wireless resource shortage. [0003] In a base station using frequency reuse technology, for example, with the popularization and application of femto (femtocell base station) equipment, a technology of how to realize frequency spectrum resource reuse in the application of femto equipment has emerged. Spectrum resource reuse needs to consider the problem of adjacent cell interference. In related technologies, usually adjacent femtos use orthogonal sub-bands to...
