Description

Indicating means, base station and user terminal to multiplexing service position

Technical field

The present invention relates to communication technical field, relate in particular to a kind of indicating means, base station and user terminal multiplexing service position.

Background technology

Along with the development of 3G (Third Generation) Moblie technology, 3G (Third Generation) Moblie can provide as visual telephone, picture download, the more service of high data rate of high speed browsing internet (Internet) geometric ratio second generation mobile communication, thereby supports the multiple business form.Wherein have a class business can by air interface give once subscribed in the wireless network should business all online user's terminals send such as programs such as weather forecast, news film, the sports tournament collection of choice specimens, mobile TVs, and need not set up man-to-man the connection with each user terminal.Such business is multimedia broadcast multi-broadcasting business (MBMS).

Multimedia broadcast multi-broadcasting business has defined a plurality of channels, multicast control channel (MCCH) for example, multicast transmission channel (MTCH) etc.The control information of the main transport service of multicast control channel, this control information comprise service lists, professional beginning or finish indication, professional semi-persistent scheduling information etc.Professional semi-persistent scheduling information such as modulation coding mode, initial subframe etc.Except multicast control channel and multicast transmission channel, also may there be multicast scheduling channel (MSCH).Multicast scheduling channel implicit expression or the explicit schedule information of each multicast transmission channel in certain dispatching cycle of having indicated, promptly each multicast transmission channel occupancy which sub-frame resources.Because the multicast control channel carrying is semi-persistent scheduling information, it is slow that schedule information is compared in variation, thereby being also referred to as dynamic scheduling information with respect to this schedule information, the frequency that the semi-persistent scheduling information of multicast control channel transmission occurs also is lower than the frequency of occurrences of dynamic scheduling information.Dynamic scheduling information can also be carried by other carrier such as non-MSCH, all uses dynamic scheduling information one speech in subsequent descriptions.

Wherein, sub-frame resources promptly sends under the situation of identical data with identical temporal frequency resource in a plurality of sub-districts, the wireless sub-frame resource that is used for the multicast and broadcast transmission of the Broadcast Control Channel of sub-district (BCCH) broadcasting.The configuration information that the while Broadcast Control Channel is broadcasted these sub-frame resources comprises the cycle that sends configuration information and should can be used as multicast broadcast single frequency network (MBSFN) subframe by which wireless sub-frame in the cycle.As being the cycle, defined and which radio frames to have contained multicast broadcast single frequency network subframe in the cycle, and multicast broadcast single frequency network subframe specifically being concrete which subframe of radio frames the inside with 320ms or 32 radio frames.For the multicast and broadcast dedicated cell, ten subframes of a radio frames the inside can be used as multicast broadcast single frequency network subframe.For multicast and broadcast and clean culture mixed cell, a radio frames has 6 subframes at most as multicast broadcast single frequency network subframe in existing protocol regulation Frequency Division Duplexing (FDD) (FDD) system; 5 subframes are arranged as multicast broadcast single frequency network subframe at most for radio frames in time division duplex (TDD) system.With the frequency division duplex system is example, then contains 32 * 6=192 subframe among the 320ms at most as multicast broadcast single frequency network subframe.Support the demand of 16 television channels simultaneously for the 5M bandwidth that in Long Term Evolution plan (LTE), proposes with the speed rates of 300kbps, each television channel on average can be assigned to 192/16=12 multicast broadcast single frequency network subframe, and the requirement of the speed of 300kbps also can be satisfied by dispatching 18 multicast broadcast single frequency network subframes.These multicast broadcast single frequency network subframes are the carrier of multicast control channel, multicast transmission channel, dynamic scheduling information.

For the transmission of saving base station system is consumed energy, and save the wireless sub-frame resource, different multicast transmission channels are multiplexed in together.With the TV programme is example, because the compression of television image frame makes that the data volume size of (for example 320ms) is variable in the final time period along with the variation of time, thus a plurality of television channels are together multiplexing, can more economize on resources.Like this, different dispatching cycle (example) as 320ms), the shared multicast broadcast single frequency network subframe starting point of each multicast transmission channel may be different with end point, and the feasible definite starting and ending multicast broadcast single frequency network subframe of each multicast transmission channel occupancy in dispatching cycle of indicating is more important.

In the prior art, a kind of indicating means is that Multimedia Broadcast Multicast Service is classified into can not multiplexing service and multiplexing service group.Multiplexing service group the inside comprises the service lists that is re-used.Multicast control channel indicates can not multiplexing service and the beginning subframe of multiplexing service group, indicates the end subframe of all business then in the dynamic scheduling information the inside.With Frequency Division Duplexing (FDD) and mixed carrier system is example, because the 320ms the inside has 192 multicast broadcast single frequency network subframes at most, per 8 bits are represented the end subframe numbers of a business in dynamic scheduling information, user terminal is according to the end subframe numbers in the dynamic scheduling information and can not multiplexing service and the beginning subframe of multiplexing service group, the multicast broadcast single frequency network subframe resource information that the business of obtaining takies.Because the business that is re-used can only when previous business just in time takes a subframe, can cause the user terminal mutiread to get a subframe with the end subframe of the previous business initial subframe as oneself.If the professional reality that active user's terminal receives only takies a subframe, the number of sub frames that such mutiread is got will reach 50%.Therefore there are inaccurate characteristics in this kind indicating means.

Another kind of indicating means is indicated each multicast transmission channel shared multicast broadcast single frequency network subframe starting point and end point by dynamic scheduling information.Wherein dynamic scheduling information comprises each multicast transmission channel or professional initial subframe and the sub-frame number that takies.User terminal is according to initial subframe and sub-frame number in the schedule information, the multicast broadcast single frequency network subframe resource information that the business of obtaining takies.

In realizing process of the present invention, the inventor finds that there is following defective at least in prior art: it is more that dynamic scheduling information takies resource.

Dynamic scheduling information no longer provide can not multiplexing service schedule information, thereby further reduced the data volume of dynamic scheduling information, saved air interface resource.

After user terminal receives indication in dynamic scheduling information and the multicast control channel, can by in dynamic scheduling information and the multicast control channel can not multiplexing service indication calculate and obtain professional initial subframe, promptly the business of in the dynamic scheduling information that adds up, indicating take sub-frame number the time add the number of subframes of the fixed length business of the not reusable of before professional K, dispatching.Sub-frame number-multiplexing service 1 that the shared sub-frame number+multiplexing service of the multiplexing service that provides in the shared sub-frame number+dynamic scheduling information of the multiplexing service of indicating in the initial subframe=multicast control channel as multiplexing service 3012 is shared-service numbers is shared bits value=2+1+1-0-1-1=2 of 2.

Another flow chart that Fig. 8 provides for the embodiment of the invention to the indicating means of multiplexing service position.This method comprises:

Step 81, by multicast control channel send can not multiplexing service initial subframe and the initial subframe of multiplexing service group.

This action can be carried out by the base station.In the present embodiment, the base station is classified into business can not multiplexing service and multiplexing service group, and providing each on multicast control channel can not multiplexing service and the initial subframe of multiplexing service group, and in dynamic scheduling information not to adding shared bits by multiplexing service.

Step 82, the dynamic scheduling information of the shared bits include can not multiplexing service shared sub-frame number and each multiplexing service and shared sub-frame number is set; Described shared bits sees the explanation of above-mentioned steps 11 for details.

This action can be carried out by the base station.The base station is provided with dynamic scheduling information, and providing can not shared sub-frame number and the shared bits of each multiplexing service and the shared sub-frame number of multiplexing service.

Step 83, send described dynamic scheduling information, the initial subframe that sends according to described dynamic scheduling information and described multicast control channel with indicating user terminal is obtained the initial subframe of each multiplexing service.

This action can be carried out by the base station.The base station sends to user terminal with dynamic scheduling information,

With accordingly embodiment illustrated in fig. 8, Fig. 9 provide for the embodiment of the invention another obtain the flow chart of the method for multiplexing service position.This method comprises:

Step 91, receive that multicast control channel sends can not multiplexing service initial subframe and the initial subframe of multiplexing service group;

This action can be carried out by user terminal.User terminal by multicast control channel obtain can not multiplexing service initial subframe and the initial subframe of multiplexing service group.

Step 92, receive the dynamic scheduling information of the shared bits include can not multiplexing service shared sub-frame number and each multiplexing service and shared sub-frame number; Described shared bits sees the explanation of above-mentioned steps 11 for details.

This action can be carried out by user terminal.User terminal receives dynamic scheduling information, and acquisition can not shared sub-frame number and the shared bits of each multiplexing service and the shared sub-frame number of multiplexing service.

Step 93, the initial subframe that sends according to described dynamic scheduling information and described multicast control channel are obtained the initial subframe of each business.

This action can be carried out by user terminal.User terminal is on the initial basis of sub-frames that multicast control channel provides, and the sub-frame number that provides according to dynamic scheduling information obtains the initial subframe of each multiplexing service.

When still being example with multicast and broadcast service scheduling information shown in Figure 3, can provide the initial subframe 0 of multiplexing service 0 and the initial subframe 2 of multiplexing service group in multicast control channel, at this moment, the indication in the dynamic scheduling information is as shown in table 2.

User terminal can according to the information on the multicast control channel obtain can not multiplexing service initial subframe.For the business in the reusable service groups, can obtain the initial subframe of first business in the multiplexing service group according to the initial sub-frame information of the multiplexing service group on the multicast control channel, the subsequent reuse business can obtain the initial subframe of each business in the multiplexing service group according to the sub-frame number of each multiplexing service in the initial sub-frame information of multiplexing service group and the dynamic scheduling information.It as the initial subframe of multiplexing service 1 the initial subframe 2 of the multiplexing service group that provides on the multicast control channel; Sub-frame number-multiplexing service 1 that the initial subframe+multiplexing service 1 of the initial subframe=multiplexing service 1 of multiplexing service 2 is shared=2+1-1=2; Sub-frame number-multiplexing service 1 that the shared sub-frame number+multiplexing service of the initial subframe+multiplexing service 1 of the initial subframe=multiplexing service 1 of multiplexing service 32 is shared-service numbers is shared bits value=2+1+1-1-1=2 of 2.

Among the above-mentioned indicating means embodiment to multiplexing service position, also the excursion of the sub-frame resources quantity that can take in a dispatching cycle according to business should business be sorted out, promptly according to excursion on multicast control channel, indicate in the dynamic scheduling information should business the shared bit number of sub-frame number, also be that dynamic scheduling information is indicated this professional sub-frame number with several bits.Suppose that a certain business may take 0 to 2N-1 subframe in a dispatching cycle, then the bit number that indication is used to identify the shared sub-frame number of this business on the multicast control channel is N, correspondingly indicates this business shared sub-frame number in current dispatching cycle with N bit in dynamic scheduling information.

After user terminal receives the classified information such as N of indicating on the multicast control channel, then from dynamic scheduling information, read the shared sub-frame number of this business according to N bit.

Like this, the actual subframe that is used for indicating services in dynamic scheduling information the inside takies several bit numbers and just can be provided with flexibly according to the difference of business, thereby by take the excursion of sub-frame resources number at the multicast control channel indicating services, further reduced bit number shared in the dynamic scheduling information, saved air interface resource the indication of number of services.

The sub-frame number that the foregoing description takies by indicating services implicitly indicates the initial subframe of each business and finishes subframe, and need not indicate initial subframe or finish subframe, because the sub-frame number that each business took in dispatching cycle approximately is about 192/16=12, so the indication to sub-frame number in the dynamic scheduling information approximately just can meet the demands with 4 to 5 bits, has reached efficient purpose of indicating.Even add shared bits, each professional indication bit number mostly is 5 to 6 bits most, uses initial subframe or finishes 8 required bits of subframe so compare, and has saved the data volume more than 25%.And guaranteed that user terminal can accurately calculate the initial subframe of each Multimedia Broadcast Multicast Service and finish subframe according to above-mentioned information fully.Like this, the multicast control channel of format and dynamic scheduling information with the Data-carrying of less amount amount of information same as the prior art, make in the base station in the transmission of user terminal, saved air interface resource in short supply.

In addition, each professional shared bits and initial subframe or end subframe also can be set in the dynamic scheduling information.As shown in figure 10, another flow chart of providing for the embodiment of the invention of Figure 10 to the indicating means of multiplexing service position.This method comprises:

Step 101, the dynamic scheduling information of the shared bits include each multiplexing service in the multiplexing service group and the initial subframe of described each multiplexing service is set, or setting includes the dynamic scheduling information of the end subframe of the shared bits of each multiplexing service in the described multiplexing service group and described each multiplexing service; Described shared bits is used to represent whether described each multiplexing service and follow-up business take a subframe jointly, see the explanation of above-mentioned steps 11 for details.

This action can be carried out by the base station.When the base station is provided with the shared bits of multiplexing service and initial subframe in dynamic scheduling information, the end subframe that user terminal can obtain each business by the initial subframe and the shared bits of multiplexing service.When the base station is provided with the shared bits of multiplexing service and finishes subframe in dynamic scheduling information, the initial subframe that user terminal can obtain each business by the end subframe and the shared bits of multiplexing service.

If include in the Multimedia Broadcast Multicast Service that the base station sends can not multiplexing service the time, can further in dynamic scheduling information, be provided with can not multiplexing service shared bits and initial subframe; Or be provided with can not multiplexing service shared bits with finish subframe.Information that can not multiplexing service also can send to user terminal by multicast control channel.

Step 102, send described dynamic scheduling information, obtain the end subframe of described each multiplexing service with indicating user terminal according to described shared bits and described initial subframe, or obtain the initial subframe of described each multiplexing service according to described shared bits and described end subframe.

This action can be carried out by the base station.The base station sends dynamic scheduling information to user terminal, and user terminal just can obtain each professional shared bits and initial subframe by dynamic scheduling information, or shared bits and end subframe, thereby obtains the schedule information of multicast transmission channel.As when being each professional shared bits and initial subframe in the dynamic scheduling information, the end subframe of professional K can be calculated acquisition by the initial subframe of professional K+1 and the shared bits of professional K; When in the dynamic scheduling information being each professional shared bits and end subframe, the initial subframe of professional K can be calculated acquisition by the end subframe of professional K-1 and the shared bits of professional K-1.

This action can be carried out by user terminal.User terminal receives dynamic scheduling information, obtains the shared bits and the initial subframe of multiplexing service, or shared bits and end subframe.

Step 112, obtain the end subframe of described each multiplexing service, or obtain the initial subframe of described each multiplexing service according to described shared bits and described end subframe according to described shared bits and described initial subframe.

This action can be carried out by user terminal.When user terminal obtains each professional shared bits and initial subframe, need to obtain the end subframe of each business, just can obtain the schedule information of multicast transmission channel.When user terminal obtains each professional shared bits and finishes subframe, need to obtain the initial subframe of each business, just can obtain the schedule information of multicast transmission channel.Computational methods see the explanation of above-mentioned steps 102 for details.If what dynamic scheduling information provided is each professional shared bits and initial subframe, the end subframe of professional K can be calculated acquisition by the initial subframe of professional K+1 and the shared bits of professional K.Particularly, when the value of the shared bits of professional K was 0, the end subframe of professional K was the initial subframe-1 of professional K+1; When the value of the shared bits of professional K was 1, the end subframe of professional K was the initial subframe of professional K+1.If what dynamic scheduling information provided is each professional shared bits and end subframe, the initial subframe of professional K can be calculated acquisition by the end subframe of professional K-1 and the shared bits of professional K-1.Particularly, when the value of the shared bits of professional K-1 was 0, the initial subframe of professional K was end subframe+1 of professional K-1; When the value of the shared bits of professional K-1 was 1, the initial subframe of professional K was the end subframe of professional K-1.

If include in the Multimedia Broadcast Multicast Service that the base station sends can not multiplexing service the time, user terminal also can be further according to be provided with in the dynamic scheduling information can not multiplexing service shared bits and initial subframe, or be provided with can not multiplexing service shared bits with finish subframe and obtain all professional schedule informations.User terminal also can be further according to multicast control channel send can not multiplexing service information obtain all professional schedule informations.
