Description
Technical field
The present invention relates to Long Term Evolution (LTE, Long Term Evolution) system, relate in particular to a kind of multimedia broadcasting and multicast service (MBMS, the implementation method and the system of transmission channel Multimedia Broadcast Multicast Service) (MTCH, MBMS Traffic Channel) carrying.
Background technology
Along with the fast development of Internet and popularizing of large-screen multi-functional mobile phone, a large amount of mobile data multimedia services and various high bandwidth multimedia service have appearred, for example, video conference, television broadcasting, video request program, advertisement, online education, interactive game etc., like this, both satisfy the business demand that the mobile subscriber constantly rises, brought new business growth point for mobile operator again simultaneously.These mobile data multimedia services require a plurality of users can receive identical data simultaneously, compare with general data service, have characteristics such as data volume is big, longer duration, delay sensitive.
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd Generation Partnership Project) the MBMS business has been proposed, this MBMS business is to transmit the technology of data to a plurality of targets from a data source, realized comprising that the Internet resources of core net and Access Network are shared, Internet resources have been improved, especially the utilance of air interface resource.The MBMS business of 3GPP definition not only can realize the classes of messages multicast and the broadcasting of plain text low rate, but also can realize the broadcasting and the multicast of high-speed multimedia business, multiple rich video, audio frequency and multimedia service are provided, this has complied with the trend of following mobile data development undoubtedly, for the development of 3G provides better professional prospect.
In LTE, the MBMS business can adopt the mixed carrier mode to send, and the mixed carrier mode is meant unicast service, and the multicast service of many cell patterns is that the MBMS business sends on same carrier wave in time-multiplexed mode, and time-multiplexed least unit is a subframe.Stipulate among the LTE at present, use the collocation method of dual unit to dispose the radio frames and the subframe of carrying the MBMS business, specifically describe as follows:
The first order realizes the radio frames configuration of carrying MBMS business, the equation SFN mod radioFrameAllocationPeriod=radioFrameAllocationOffset below satisfying.
Wherein, SFN is the abbreviation of System Frame Number System Frame Number, and promptly the radio frames of system is numbered, from 0 to 1023.RadioFrameAllocationPeriod represents multimedia broadcasting single frequency network (MBSFN) wireless frame period, its can get 1,2,4,8,16, and among the 32} any one.RadioFrameAllocationOffset represents the skew of MBSFN radio frames, and its value is an integer and less than the numerical value of selected MBSFN wireless frame period, more than or equal to 0.Mod represents that SFN is to radioFrameAllocationPeriod delivery or complementation.Above-mentioned be configured to carry the professional radio frames of MBMS and be called the MBSFN radio frames.
The second level is realized concrete which the subframe carrying MBMS business in the professional radio frames of carrying MBMS, uses the method for bit map (bitmap), owing to stipulate that subframe #0, #4, #5, #9 can not carry the MBMS business under Frequency Division Duplexing (FDD) (FDD) pattern among the LTE; Subframe #0, #1, #5, #6 can not carry the MBMS business under time division duplex (TDD) pattern, therefore, use the bitmap of 6 bits to describe which carrying MBMS business of remaining 6 subframes.The sub-frame configuration of the carrying MBMS business in each MBSFN radio frames is identical.Because the dual unit configuration signal sends to terminal on system broadcast message (BCCH, Broadcast Control Channel), therefore, the sub-frame configuration in the MBSFN radio frames in each BCCH modification cycle can not change.The subframe of carrying MBMS business is called the MBSFN subframe in the above-mentioned MBSFN radio frames, also claims multicast subframe.
At present preceding 1 or 2 OFDM (OFDM of MBSFN subframe in LTE, Orthogonal Frequency Division Multiplexing) symbol is used to transmit the control information of unicast service, be also referred to as Physical Downlink Control Channel (PDCCH, Physical Downlink Control CHannel), in this subframe residual resource to be used for sending MBMS professional or other are professional.
Can realize the configuration of MBSFN radio frames and MBSFN subframe by the collocation method of above-mentioned existing dual unit, the MBSFN subframe that configures is exactly the physical resource that has constituted actual transmissions MBMS business, be physics multicast channel (PMCH, Physical Multicast CHannel).PMCH bear multicast channel (MCH, Multicast Channel).MCH is the multicast transmission channel of LTE regulation, and a series of MBSFN subframes that disposed by the collocation method by dual unit constitute.Further, do not get rid of MCH among the LTE R9 and can be divided into a plurality of MCH by rule.For example, by the part MBSFN subframe in the MBSFN subframe of dual unit configuration as MCH1, remaining MBSFN subframe as MCH2.
In the LTE Ran2 65bis meeting among the decision LTE R9 regulation MTCH be mapped among the MCH and carry, but also do not provide concrete carrying, mapping mode at present.So, how should MTCH be carried on MCH and go up? the data volume of considering the MTCH of the different MBMS business of carrying differs bigger, more needs a kind of load multiplexing method on MCH that can be fit to different MTCH here; To consider that also a MTCH uses the carrying under a plurality of complete subframes and the parton frame condition; And when the MBMS of single sub-district business model, how multiplexing in subframe the MTCH of unicast service and multicast service is, all do not provide the method for solution.In sum, at present, there is not the specific implementation of relevant MTCH carrying.

Embodiment
Basic thought of the present invention is: when the data volume of a certain MTCH surpasses a MBSFN subframe, for a plurality of MBSFN subframes that the data allocations of this MTCH is continuous are used.When a certain MTCH data carried by data amount does not surpass a MBSFN subframe,, uses this MTCH for distributing a MBSFN subframe.
Be described in further detail below in conjunction with the enforcement of accompanying drawing technical scheme.
A kind of implementation method of MTCH carrying, this method is at the difference of MTCH data carried by data amount, comprise two kinds of specific implementations, first kind of specific implementation is: when a certain MTCH data carried by data amount surpasses a MBSFN subframe, use for this MTCH distributes continuous, complete, a plurality of MBSFN subframes, realize the Data-carrying of MTCH; This moment, the high priority data of MTCH was filled in a plurality of MBSFN subframes of being distributed continuously, not the data of other MTCH of carrying in these MBSFN subframes.Second kind of specific implementation is: when a certain MTCH data carried by data amount does not surpass a MBSFN subframe, use for this MTCH distributes a MBSFN subframe, realize the Data-carrying of MTCH; This moment, the data of MTCH can be monopolized this subframe, also can share a subframe with MTCH.Employing the present invention is directed to the difference of MTCH data carried by data amount, comprise two kinds of different specific implementations, so, just provide higher, resource allocation granularity more flexibly for the carrying of MTCH, reduced MTCH waste to resource in carrying, thus the spectrum efficiency of elevator system.
Wherein, with regard to first kind of specific implementation, use a plurality of MBSFN subframes to realize that the Data-carrying of MTCH is specially: the preferential filling time of MTCH data carried by data is gone up forward MBSFN subframe.
Here under the MBMS business model that it is pointed out that in many sub-districts or the MBMS business model of single sub-district, have nothing in common with each other, below set forth respectively at above two kinds of specific implementations.And, terse in order to describe, below the MBMS business model of many sub-districts is called many cell patterns; The MBMS business model of single sub-district is called single cell pattern.
Under many cell patterns, at above first kind of specific implementation, under many cell patterns, use a plurality of MBSFN subframes to realize under the Data-carrying situation of MTCH, when the remaining data volume of current MTCH can not be filled a full complete current MBSFN subframe, the multiplex mode that adopts specifically comprises two kinds of situations, first kind of situation: current MTCH and other MTCH is multiplexing in current MBSFN subframe; Second kind of situation: current MTCH is not multiplexing in current MBSFN subframe with other MTCH, that is to say, only carry current MTCH in the current MBSFN subframe.Wherein, carrying out the described base unit that adopts when multiplexing comprises: Physical Resource Block (PRB) or OFDM symbol, subcarrier or cluster of subcarriers.
Under many cell patterns, at above second kind of specific implementation, under many cell patterns, use a MBSFN subframe to realize under the Data-carrying situation of MTCH, when the data volume of current MTCH self can not be filled a full complete MBSFN subframe, the multiplex mode that adopts specifically also comprises two kinds of situations, first kind of situation: directly that current MTCH and other MTCH is multiplexing in the MBSFN subframe; Second kind of situation: current MTCH is not multiplexing in the MBSFN subframe with other MTCH, that is to say, only carry current MTCH in the MBSFN subframe.Wherein, carrying out the described base unit that adopts when multiplexing comprises: PRB or OFDM symbol, subcarrier or cluster of subcarriers.
Here it is to be noted, under many cell patterns, also has a kind of specific implementation, specifically, under many cell patterns, use a MBSFN subframe to realize the Data-carrying of MTCH, and under MBMS service conditions of a MTCH carrying, as shown in Figure 1, the multiplex mode of employing may further comprise the steps:
Here, a plurality of MTCH after binding this moment can not fill full MBSFN subframe.
Also can be in a MTCH MBMS bundling with identical QOS, at this moment owing to bundled a plurality of MBMS business, so this MTCH can fill full subframe.
A plurality of MTCH after step 102, the binding are in this MBSFN subframe of distributing, and it is multiplexing to be with PRB, OFDM symbol, subcarrier or cluster of subcarriers that base unit carries out.
Here, in addition, under many cell patterns, also has another kind of specific implementation, specifically, under many cell patterns, use the Data-carrying of an integer MBSFN subframe realization MTCH, and a MTCH carries under a plurality of MBMS service conditions, as shown in Figure 2, the multiplex mode of employing may further comprise the steps:
Here, a MTCH after binding this moment can not fill full MBSFN subframe far away.
A MTCH after step 202, the binding is in an integer MBSFN subframe of current distribution, and it is multiplexing to be with PRB, OFDM symbol, subcarrier or cluster of subcarriers that base unit carries out.
It is to be noted: under single cell pattern, because not having the MBMS service bearer of instruction book cell pattern at present still is common unicast sub in the MBSFN subframe, therefore the professional employed subframe of the MBMS of single cell pattern is not limited in the present invention, the MBSFN subframe still is that common unicast sub can adopt.
Under single cell pattern, at above first kind of specific implementation, use subframe to realize under the Data-carrying situation of MTCH, when the remaining data volume of current MTCH can not be filled a full complete current subframe, the multiplex mode of employing specifically comprised: with current MTCH and other MTCH or non-MBMS business datum for example the unicast service data in current subframe, carry out multiplexing.Wherein, carrying out the described base unit that adopts when multiplexing comprises: PRB, OFDM symbol, subcarrier or cluster of subcarriers.
Under single cell pattern, at above second kind of specific implementation, under single cell pattern, use a subframe to realize under the Data-carrying situation of MTCH, when the data volume of current MTCH self can not be filled a full complete subframe, the multiplex mode of employing specifically comprised: directly for example the unicast service data are multiplexing in subframe with current MTCH and other MTCH or non-MBMS business datum.Wherein, carrying out the described base unit that adopts when multiplexing comprises: PRB, OFDM symbol, subcarrier or cluster of subcarriers.
In sum, main contents of the present invention comprise following content:
The first, for the MBMS of many cell patterns is professional, the MTCH data volume surpasses under the situation of a MBSFN subframe, and MTCH when multiplexing, is that the continuous complete MBSFN subframe of MTCH priority allocation is used on MCH.Here, when the remaining data volume of MTCH can not be filled a full complete MBSFN subframe, two kinds of processing modes are arranged, first kind of mode: this MTCH can carry out multiplexing in this subframe with other MTCH.Can be base unit with PRB, OFDM symbol, subcarrier or cluster of subcarriers when multiplexing.The second way: this MTCH does not carry out multiplexingly with other MTCH, only carries this MTCH in this subframe.
The data volume of MTCH own just can not be filled under the situation of a full MBSFN subframe, two kinds of processing modes is also arranged, first kind of mode: directly this MTCH and other MTCH, perhaps with non-MBMS business datum for example the unicast service data carry out in the subframe multiplexing.Can be base unit with PRB, OFDM symbol, subcarrier or cluster of subcarriers when multiplexing.The second way: this MTCH does not carry out multiplexing with other MTCH.
The second, for the MBMS of single cell pattern is professional, the MTCH data volume surpasses under the situation of a subframe, during MTCH multiplexing on the sub-frame data territory, is that the continuous complete subframe of MTCH priority allocation is used.Here, when the remaining data volume of MTCH can not be filled a full complete subframe, the mode of employing was: this MTCH can with other MTCH or non-MBMS business datum for example the unicast service data in this subframe, carry out multiplexing.Can be base unit with PRB, OFDM symbol, subcarrier or cluster of subcarriers when multiplexing.
The data volume of MTCH own just can not be filled under the situation of a full MBSFN subframe, directly this MTCH and other MTCH or non-MBMS business datum for example the unicast service data carry out in the subframe multiplexing.Can be base unit with PRB, OFDM symbol, subcarrier or cluster of subcarriers when multiplexing.
Here it is to be noted: the implementation method of the MTCH carrying that the present invention describes also is fit to the realization of MCH carrying.Only need replace with MCH to MTCH gets final product.
Here it is to be noted: with the present existing technology of LTE as a setting, introduce the present invention and specifically how to use.Being in the following example with the subframe internal resource under the Cyclic Prefix (CP, Cyclic Prefix) of expansion is that example is described.Expansion CP and standard C P cause the difference of subframe internal resource to be: during expansion CP, the inherent time orientation of subframe is 12 OFDM symbols; During standard C P, the inherent time orientation of subframe is 14 OFDM symbols.The interior resource of subframe obtains different Resource Block according to different division methods among the LTE at present.For example, it is the Resource Block of unit that Resource Block can obtain with the OFDM symbol, and also can obtain with PRB is the Resource Block of unit, and also can obtain with subcarrier or cluster of subcarriers is the Resource Block of unit.At present, preceding 1 or 2 OFDM of regulation MBSFN subframe are used to carry PDCCH in LTE R9, and for unicast service is served, residual resource is used for the MBMS transmission business, is used for carrying MTCH specifically, does not carry unicast service.So in the good a series of MBSFN subframes of system configuration, how distribute the resource of oneself for each MTCH? below to the elaboration of giving an example of the present invention's content described above.Below example if not otherwise specified, think that all each MTCH correspondence only carries the data of a MBMS business.And example one and example two are: the specific implementation of MTCH carrying; Example three～example five is: MTCH is carried on multiplexing specific implementation in the MBSFN subframe; Example six is: MTCH is the multiplexing specific implementation of base unit with the MBSFN subframe.
Below the example one, two, three, four, six, seven of concrete application also be to be fit to MCH, only need in the example one, two, three, four, six, seven MTCH to replace with MCH and get final product.
Example one: for the MTCH average amount surpassed the situation of a MBSFN subframe, system side was distributed corresponding bearer resource according to the data carried by data amount of each MTCH for it.Specifically, for distributing continuous MBSFN subframe, each MTCH is used for carrying the data of MBMS business.The high priority data filling time of this MTCH is gone up forward subframe, when last MBSFN subframe is expired in the not enough filling of the remaining data volume of this MTCH, can handle according to following dual mode.
First kind of mode: continuing with PRB, OFDM symbol, subcarrier or cluster of subcarriers is that base unit is filled last MBSFN subframe, but this MBSFN subframe is no longer carried other MTCH data.The second way: continuing with PRB, OFDM symbol, subcarrier or cluster of subcarriers is that base unit is filled last MBSFN subframe, and allowing other MTCH to continue with PRB, OFDM symbol, subcarrier or cluster of subcarriers for this MBSFN subframe residual resource is that base unit is filled.
Multiplexing reference in the concrete subframe describes below MTCH and carry out multiplexing example three～example five in subframe.
Beneficial effect is: in the time of can not filling full MBSFN subframe for the data volume of MTCH, allow the data of this part data and other MTCH multiplexing a subframe, can avoid resource waste like this.
Example two: hour for the MTCH average amount, for example can not fill the situation of a full MBSFN subframe, a kind of simple processing method is: system side is directly distributed a MBSFN subframe for this MTCH, and other MTCH of discord carry out multiplexing in this MBSFN subframe.So the easiest realization of resource allocation, the signaling consumption minimum, but the resource utilization of system is lower.Other processing method is: system side is assessed the data volume of each MTCH, after a plurality of suitable MTCH bindings, makes it can fill full MBSFN subframe, the full MBSFN subframe of perhaps very approaching filling.System side all is distributed in these MTCH on the MBSFN subframe, and a plurality of MTCH are with PRB or OFDM symbol, subcarrier or cluster of subcarriers that base unit carries out in the MBSFN subframe multiplexing.Wherein, at the data volume of each MTCH of assessment, and, will carry a plurality of MTCH bindings of MBMS business in fact exactly, a MBMS business of a MTCH carrying here with identical QOS demand a plurality of suitable MTCH bindings.
Here, give the specific implementation that a kind of MTCH of avoiding can not fill a full MBSFN subframe situation far away, specifically, further can directly be bundled in the data of a plurality of MBMS business on the MTCH, transmit by a MTCH.The principle that bundle the MBMS business this moment is the binding by a plurality of MBMS business datums, finally makes the data volume after its binding can fill a full integer MBSFN subframe, and perhaps very approaching filling is an integer MBSFN subframe completely.Wherein, directly be bundled in a MTCH at the data of a plurality of MBMS business and go up, will carry the MBMS business with identical QOS demand in fact exactly and directly be bundled in a MTCH and go up transmission, a MTCH here carries a plurality of MBMS business.
Multiplexing reference in the concrete subframe describes below MTCH and carry out multiplexing example three～example five in subframe.
Example three is: one or more MTCH is that base unit carries with PRB on the MBSFN subframe, and realizes multiplexing.
As shown in Figure 4, in subframe, a MTCH being expressed as MTCH1, is that base unit carries with PRB; Another MTCH that will be different from MTCH1 is expressed as MTCH2, also is that base unit carries with PRB, has so also just realized a plurality of MTCH multiplexing in subframe.Part resource in PRB when for example system message, control information etc. are used, should be removed occupied resource by other information from this PRB.
Beneficial effect is: for MTCH uses the PRB of the unicast service of present LTE regulation, the maximum utilance of elevator system resource in the MTCH carrying is avoided resource waste like this.Similar to the unicast service resource allocation, can directly use the control signaling format that has unicast service now.
Example four is: MTCH is that base unit carries with OFDM on the MBSFN subframe, and realizes multiplexing.
As shown in Figure 3, in subframe, a MTCH being expressed as MTCH1, is that base unit carries with the OFDM symbol; Another MTCH that will be different from MTCH1 is expressed as MTCH2, is that base unit carries with the OFDM symbol also, has so also just realized a plurality of MTCH multiplexing in subframe.Part resource in the OFDM symbol is by other information, and for example system message, control information etc. during use, should be removed occupied resource from this OFDM symbol.And, be used for carrying the OFDM symbol of MTCH in the subframe, should the OFDM symbol that PDCCH uses in next-door neighbour's subframe after.
Beneficial effect is: provide and carried out time division multiplexing between the MTCH, available smallest particles degree when the OFDM symbol is LTE system time division multiplexing.The benefit of time division multiplexing maximum is to avoid terminal to receive own uninterested business, thus power saving.
Example five is: with PRB to be that base unit carries out multiplexing for MTCH and unicast service data in subframe.It is also right and wrong MBSFN subframe unicast service subframe for example of MBSFN subframe that the subframe is not here distinguished, and both all can.The difference of additional here MBSFN subframe once and unicast service subframe, the MBSFN subframe is used expansion CP, and front 1 or 2 OFDM symbols are used for carrying PDCCH; The unicast service subframe is used long CP or is lacked CP, and 1 to 4 the OFDM symbol in front is used for carrying PDCCH, and wherein 4 OFDM symbol situations only are used for the system of 1.4M.
As shown in Figure 5, in subframe, a MTCH being expressed as MTCH1, is that base unit carries with PRB; Another MTCH that will be different from MTCH1 is expressed as MTCH2, also is that base unit carries with PRB; Is the unicast service data that user's 1 data and user's 2 data still are that base unit carries with PRB, has so also just realized multiplexing in subframe of MTCH and unicast service data.Part resource in PRB when for example system message, control information etc. are used, should be removed occupied resource by other information from this PRB.Herein, also be applicable to multicast control channel (MCCH, Multicast Control Channel), MBMS scheduling channel (MSCH, MBMS Scheduling Channel), MBMS notice indication information and unicast service data multiplex, only needing that MTCH is replaced with MCCH or MSCH or MBMS notice indication information can implement.
Beneficial effect is: for MTCH uses the PRB of the unicast service of present LTE regulation, the maximum utilance of elevator system resource in the MTCH carrying is avoided resource waste like this.Similar to the unicast service resource allocation, can directly use the control signaling format that has unicast service now.
Example six is: MTCH carries with subframe unit and is multiplexing.
Be used for carrying for each MTCH distributes an integer complete subframe, the part resource in this subframe when for example system message, control information etc. take, should be removed this part resource during carrying MTCH by other information.Even the data of MTCH can not be filled when expiring a subframe, also must distribute a subframe.
Beneficial effect is: realizes simply can avoiding terminal to receive uninterested data, thus power saving.
Example seven is: MTCH is that base unit carries with subcarrier or cluster of subcarriers on the MBSFN subframe, and realizes multiplexing.
As shown in Figure 6, in subframe, a MTCH being expressed as MTCH1, is that base unit carries with subcarrier or cluster of subcarriers; Another MTCH that will be different from MTCH1 is expressed as MTCH2, is that base unit carries with subcarrier or cluster of subcarriers also, has so also just realized a plurality of MTCH multiplexing in subframe.Be a subcarrier or cluster of subcarriers, these subcarriers or cluster of subcarriers can be continuous or discrete.Part resource in subcarrier is by other information, and for example system message, control information etc. during use, should be removed occupied resource from this subcarrier or cluster of subcarriers.
The subcarrier that the cluster of subcarriers here can be decided to be some constitutes a cluster of subcarriers, and the subcarrier that constitutes a cluster of subcarriers can also can disperse on the frequency of reality continuously.Constitute in order to meet the principle of PRB scheduling among the LTE, can be defined as a cluster of subcarriers by 12 subcarriers.
Beneficial effect is: provide and carried out frequency division multiplexing between the MTCH, available smallest particles degree when subcarrier is LTE system frequency division multiplexing.The benefit of frequency division multiplexing maximum is to obtain bigger frequency diversity gain, improves performance of services.
