Problems solved by technology

Since RB0 of sector 11 cannot be allocated to UE1 and UE2 at the same time, a conflict will occur when allocating RB0 of sector 11
Similarly, conflicts will also occur when allocating other RBs of sector 11

Embodiment Construction

[0039] The basic idea of ​​the present invention is: each cell divides frequency resources according to the number of cooperation sets, and dynamically adjusts the division ratio of resources based on frequency according to the resource ratio required by edge users of each cooperation set; The cells exchange the division ratio of their respective resources and determine the ratio of cooperation resources; according to the ratio of cooperation resources, edge users and central users are scheduled for resource allocation.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0041] The present invention implements a resource allocation method based on CoMP, such as image 3 As shown, the method includes the following steps:

[0042] Step 101: each cell performs frequency resource division according to the number of cooperating sets;

[0043] Specifically, each cell divides resources by f...

Abstract

The invention discloses a resource allocation method based on joint multipoint processing (CoMP). Each cell divides frequency resources according to the number of cooperative sets, and dynamically adjusts resources based on frequency according to the resource ratio required by edge users of each cooperative set. Division ratio; the division ratio of each resource between the serving cell and the coordination cell of each coordination set and the determination of the ratio of cooperation resources; according to the ratio of coordination resources, edge users and central users are scheduled for resource allocation; the present invention also discloses a CoMP-based The resource allocation device and the base station can solve the problem of resource allocation conflicts and avoid resource residues through the solution of the present invention.

Description

technical field [0001] The present invention relates to a joint multipoint processing (CoMP, Coordinated MultiplePoint) technology in a wireless communication system, and in particular to a CoMP-based resource allocation method, device and base station. Background technique [0002] At the beginning of 2008, the International Telecommunication Union (ITU) started the formulation of the fourth generation mobile communication (4G) standard IMT_Advanced, which especially put forward requirements on the spectrum efficiency of the cell edge. Long Term Evolution-Advanced (LTE-A), a candidate standard for 4G, introduces CoMP technology to improve cell edge performance. [0003] For cell edge users, wireless signals from adjacent cells can be received, and the transmitted signals of cell edge users can also be received by multiple evolved base stations (eNBs). Such as figure 1 As shown, multiple eNBs serve the cell edge users at the same time, thereby enhancing the communication e...
