Embodiment Construction

[0066] The technical solutions provided by the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0067] The implementation of the resource allocation method provided by the embodiment of the present invention at the resource request sending end is as follows: figure 1 As shown, it specifically includes the following operations:

[0068] Step 1. Determine resources used in the cell for CoMP scheduling.

[0069] Taking cell A as an example, resources (time-frequency resources) used by the cell (that is, cell A) for CoMP scheduling are determined.

[0070] Step 2. Send a coordinated resource request message to each neighboring cell of the cell, so as to request the resource of the cell for CoMP scheduling from each neighboring cell.

[0071] Still taking cell A as an example, a coordinated resource request message is sent to each neighboring cell of cell A.

[0072] Step 3: Receive a coordinated resource fee...

Abstract

The invention discloses a method and device for cooperation resource allocation. The method comprises the steps: 1, determining a resource, which is used for cooperating with multipoint scheduling, of a local cell; 2, transmitting cooperation resource request messages to all adjacent cells of the local cell, so as to request all adjacent cells for the resource used by the local cell for cooperating multipoint scheduling; 3, receiving cooperation resource feedback messages transmitted by all adjacent cells, wherein the cooperation resource feedback messages are used for indicating whether to accept the request of the cell for the resource used for cooperating with multipoint scheduling or not: executing step 4 if each adjacent cell accepts the request of the cell for the resource used for cooperating multipoint scheduling, distributing a cooperation resource for a terminal, and notifying an adjacent cell participating the terminal cooperation multipoint transmission of the cooperation resource allocation result, wherein the cooperation resource is all or a part of resources used by the local cell for cooperating with multipoint scheduling.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for cooperative resource allocation. Background technique [0002] Coordinated Multipoint (Coordinated MultiPoint, referred to as CoMP) transmission technology can use multiple cells to serve the same user equipment, such as jointly sending or receiving data signals for this user equipment (joint transmission / joint reception), or through multi-point joint Scheduling or beamforming can reduce the interference received by the user equipment (coordinated scheduling / coordinated beamforming), and can also provide services for the user equipment by selecting the most suitable transmission point (dynamic transmission point selection). Because the coordinated multi-point technology mainly brings gains by eliminating the interference of adjacent cells or converting the interference of adjacent cells into useful signals, it is most suitable for edge users...
