Problems solved by technology

However, there is a problem in this way: if a certain MCH only allocates a part of the MBSFN subframes in a certain MBSFN frame, the resource allocation of another part of the MBSFN subframes will be wasted if the frame is allocated.

Embodiment Construction

[0025] At first, explain the key of the present invention:

[0026] 1. The resource allocation granularity of each MCH is MBSFN subframe;

[0027] 2. Extract the MBSFN frame and the MBSFN subframe from all the frames and subframes in one cycle, and renumber them consecutively;

[0028] 3. Each MCH allocates resources continuously. The first MCH allocates resources from the first MBSFN subframe of the first MBSFN frame, and each MCH is followed by the MBSFN frame or MBSFN subframe of the previous MCH. frame to allocate resources.

[0029] Such as figure 2As shown, the present invention is a method for allocating MBSFN subframes for one or more MCHs within one period, which specifically includes: within one period, such as a repetition period, it may also be a modification period or a scheduling period, etc., Generally 80ms, 160ms, 320ms, etc. All MBSFN frames are allocated to one or more MCHs, each MCH corresponds to one MSAP, and the MBSFN subframes configured by all MCHs...

Abstract

The invention relates to a multicast channel resource allocating method, which distributes each multicast channel to one or more MBSFN subframes. The method reduces allocation granularity, can make full use of all MBSFN frame and MBSFN subframe resources in a period to avoid resource waste; and further, any MBSFN frame has the MBSFN subframes with the same number and the subframe numbers of the MBSFN subframes are fully same, a plurality of MCHs of different MBSFN areas can be allocated to all MBSFN frames and all MBSFN subframes in a period on a network side on an MCCH channel by adopting simple order allocation, so the MBSFN frames and the MBSFN subframes allocated by the plurality of MCHs can be indicated by few bytes on the MCCH.

Description

technical field [0001] The present invention relates to wireless communication, especially in LTE (Long Term Evolution, long-term evolution) system, in one period, for one or several MBMS (Multimedia BroadcastMulticast Service, multimedia broadcast multicast service) distribute MBSFN (Multicast / Broadcastover Single Frequency Network, single frequency network multicast / broadcast) frame and subframe method. Background technique [0002] In 2005, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) launched a working group for LTE (Long Term evolution long-term evolution) research, researching and designing 3.9G (improved 3G) for the evolution of third-generation mobile communication technology next generation network. The overall goals of its design are: simple system structure, higher transmission rate, low overall cost, economical and good backward compatibility, flexible spectrum usage methods, and flexible business support capabilities.
