Description
Technical field
The present invention relates to Multimedia Broadcast Multicast Service (MBS, Multicast Broadcast Service) bearing mode indication technology, relate in particular to MBS carries in the multicast broadcasting service area territory (MBS Region) in a kind of World Interoperability for Microwave Access, WiMax (WiMAX, World Interoperabilityfor Microwave Access) network indicating means and device.
Background technology
MBS is that MBS can improve Internet resources, especially the utilance of air interface resource from the technology of a data source to a plurality of targets transmission data.Along with the application and the popularization of multimedia shared service, carry out the Multimedia Broadcast Multicast Service transmission efficiently, become particularly important for wide-band mobile communication system of future generation.
MBS based on WiMAX supports two kinds of access modules: single base station is inserted and many base stations are inserted.Under the access module of many base stations, defined the notion of MBS territory (MBS zone), i.e. the set of one group of base station, the corresponding MBS zone sign of each MBS zone (MBS zone ID).A base station can belong to a plurality of MBS zone simultaneously.Grand diversity can be carried out in a plurality of base stations that belong to same MBS zone when sending MBS, promptly send the multicast service of identical content on same running time-frequency resource, and user terminal can obtain macro diversity when receiving.
In order to satisfy high-performance in the wide-band mobile communication system of future generation and the low service application that postpones, eat dishes without rice or wine frame structure among the evolution standard 802.16m of WiMAX has adopted three layers of design of superframe, frame and subframe.Fig. 1 is a frame structures specified schematic diagram in the 802.16m standard, as shown in Figure 1.Each superframe is made up of four frames, also is provided with frame head (figure bend overlay area) before first frame, and each frame is made up of eight subframes, comprises six symbols in each subframe.
In WiMAX technology of future generation, Multimedia Broadcast Multicast Service is called the Multimedia Broadcast Multicast Service (E-MBS of enhancing, Enhanced-Multicast Broadcast Service), expectation obtains the MBS more performance than 802.16e, and the MBS zone of 802.16e is called E-MBS zone in WiMAX technology of future generation.In addition, in WiMAX technology of future generation, system has introduced multicarrier, and the carrying of E-MBS business can be adopted dual mode: a kind of is the special carrier mode, and promptly the E-MBS business is monopolized all running time-frequency resources on certain carrier wave; Another kind is to share carrier system, and promptly E-MBS business and unicast service are shared the running time-frequency resource on the carrier wave.
In the technical scheme of WiMAX of future generation, the resource allocation indication is divided into two parts: the indication of E-MBS zone (E-MBS region is also referred to as the multicast broadcasting service area territory) and the indication of E-MBS MAP.Wherein the indication in E-MBS zone is the distribution of describing the E-MBS subframe on some superframes, and these MBS subframes can belong to an E-MBS zone, also can belong to a plurality of E-MBS zone; And E-MBS MAP is the further resource allocation of E-MBS business, description be each Multimedia Broadcast Multicast Service or each the Multimedia Broadcast Multicast Service component concrete resource that arrive of an E-MBS zone in a scheduling interval.
The method indication E-MBS zone of superframe, frame, three grades of indications of subframe is arranged in the existing scheme of industry, though this mode has very strong flexibility, expense also can acutely increase along with the enhancing of flexibility.Sending because the indication information in E-MBS zone is a broadcast message, therefore, is unpractical by superframe, frame and three grades of descriptions of subframe without any the Multimedia Broadcast Multicast Service subframe of the regularity of distribution fully.
The method that also has the segmentation indication in the existing scheme of industry, promptly describe N and in the superframe whether the Multimedia Broadcast Multicast Service subframe is arranged continuously with 1 bit information, if bit value represents to contain the Multimedia Broadcast Multicast Service subframe, then all comprise the Multimedia Broadcast Multicast Service subframe in the Dui Ying N superframe, and all frames in these superframes all comprise the Multimedia Broadcast Multicast Service subframe with identical subframe distribution pattern.The indicating mode in this multicast zone be a little that expense is very little, but exist very important disadvantages: flexibility is very poor; The resource allocation granularity is too big, is 4 * N subframe; When resource requirement hour, may need share out equally on a lot of frames because the resource allocation granularity is excessive on the other hand because granularity problem can not be finished distribution on the one hand, the Multimedia Broadcast Multicast Service sub-frame number of every frame is fewer, is unfavorable for the terminal power saving.
