Method and apparatus for distributing time frequency resource

Abstract

The embodiment of the invention discloses a time-frequency resource allocating method used for a multicast service of media broadcasting. The method comprises the following steps: an MBSFN (multicast broadcasting single frequency network) area is matched with each adjacent area in a gathering way; the adjacent areas which satisfy the preset matching requirements are selected to allocate the time-frequency resources of the MBSFN area in a gathering way. The embodiment of the invention further discloses a time-frequency resource allocating equipment. By utilizing the embodiment of the invention, the MBSFN area is matched with the adjacent areas in a gathering way and the resources are allocated according to the matching condition, thus leading more small areas to use the same time-frequencyresources, increasing the gains of the combination of the small areas, and avoiding the contradiction that remains of the time-frequency resources are incurred in the random allocation, but no resources can be allocated at present.

Description

A method and device for allocating time-frequency resources technical field The present invention relates to the field of communication technologies, and in particular to a method and device for allocating time-frequency resources. Background technique MBMS (MultimediaBroadcastandMulticastService, Multimedia Broadcast Multicast Service) refers to a point-to-multipoint service in which a data source sends data to multiple users, which can realize network resource sharing, including mobile core network and access network resource sharing, especially air interface resource sharing . MBMS defined by 3GPP (the3rdGenerationPartnerProject, Third Generation Partnership Project) can not only realize plain text low-rate message multicast and broadcast, but also realize high-rate multimedia multicast and broadcast, conforming to the trend of future mobile data development . According to the distribution of users receiving services, MBMS has two transmission modes, one is multi-cel...

Problems solved by technology

Embodiments of the present invention provide a method and device for allocating time-frequency resources, so as to solve the problem of how to re-allocate when MCE has no standard to follow when resource allocation selection fails in multi-cell transmission mode.
