Description

The transmission of information, receiving handling method and equipment in a kind of long evolving system
Technical field
The present invention relates to wireless communication technology, transmission, receiving handling method and the equipment of information in particularly a kind of long evolving system.
Background technology
MBMS (Multimedia Broadcast/Multicast Service, multimedia broadcasting multicast service) technology is used to that the user provides multimedia broadcasting and multicast services in the wireless area.In LTE (Long Term Evolution, the Long Term Evolution) system, the frequency layer of MBMS special use and with the professional frequency layer of sharing of non-MBMS on MBMS can both be provided.Support that the LTE sub-district of MBMS can be that the MBMS dedicated cell also can be a MBMS/ clean culture mixed cell.MBMS can carry out single cell transmission, also can carry out many cell transmission.
In the foregoing, MBMS dedicated frequency layer is meant the frequency layer that is specifically designed to the MBMS transmission.When a sub-district is configured to MBMS dedicated frequency layer, claim that this sub-district is the MBMS dedicated cell; Being configured to when a sub-district is not when being specifically designed to the frequency layer of MBMS transmission, claim that this sub-district is a MBMS/ clean culture mixed cell, that is: in MBMS/ clean culture mixed cell, unicast service and MBMS are collaborative to be transmitted, some is used for the MBMS transmission constantly, and other the moment is used for the unicast service transmission.Single cell transmission of MBMS is meant that MBMS only transmits in the coverage of a designated cell, do not support the merging that the MBMS from other sub-districts is transmitted; Many cell transmission of MBMS adopt MBSFN (MBSFNMulticast Broadcast Single Frequency Network, Multicast Broadcast Single Frequency Network) transmission means.
So-called MBSFN is meant the transmission means that sends identical content at one time with same frequency in a plurality of sub-districts simultaneously.So, UE (User Equipment, subscriber equipment) receiver just can be considered as a plurality of MBSFN sub-district a big sub-district, not only can not be subjected to the presence of intercell interference of neighbor cell transmission, and will benefit from the stack from the signal of a plurality of MBSFN sub-district.In addition, if utilize advanced UE receiver technology can also solve the time difference problem of multipath transmisstion, disturb thereby eliminate in the sub-district.This multiple sectors at same keeps pouring in to fail and not only can improve the availability of frequency spectrum, and the diversity that is brought can also solve problems such as blind area covering, strengthens the reliability that receives, and improves coverage rate.MBMS dedicated cell and MBMS/ clean culture mixed cell can adopt the MBSFN transmission means.
Because the MBSFN transmission relates to the synchronous transmission of a plurality of minizones, therefore there is following related definition:
(1) the MBSFN retaining zone is meant the zone of having the ability to carry out the MBSFN transmission, and all eNB (evolution base station) this zone in can be by synchronously and carry out MBSFN and transmit.The MBSFN retaining zone can be supported one or more MBSFN zone.On given frequency layer, each NodeB/eNodeB (base station/evolution base station) can only belong to a MBSFN retaining zone.
(2) the MBSFN zone is made up of a group sub-district in the MBSFN retaining zone scope of network, and these sub-districts coordinate to realize the MBSFN transmission mutually.A sub-district in MBSFN retaining zone scope can become the part in a plurality of MBSFN zone.Each MBSFN zone can have different transmission contents to participate in set with different sub-districts.For the UE that receives the MBSFN transmission, whole M BSFN zone can be counted as a MBSFN sub-district.
The MBSFN retaining zone generally realizes by configuration, and the MBSFN zone both can also can be realized by dynamic management by configuration.
MBMS need transmit by corresponding logic channel and transmission channel.Logic channel is MAC (Medium Access Control, medium access control) layer definition and interface upper-layer protocol, and MAC provides data transmission service for logic channel, and logical channel type is used to distinguish the type of data transmission service.Transmission channel is the interface that is used to transmit data that physical layer provides to layer 2 (as: MAC layer), and the type of transmission channel defines according to the transmission feature and the transmission means of data on physical layer.In the LTE system, the logic channel relevant with the MBMS transmission mainly contains: BCCH (Broadcast Control Channel, Broadcast Control Channel), MCCH (Multicast Control Channel, multicast control channel) and MTCH (MBMS Traffic Channel, the MBMS Traffic Channel), transmission channel mainly contains: MCH (Multicast Channel, Multicast Channel) and DL-SCH (DL-Shared CHannel, DSCH Downlink Shared Channel).Fig. 1 is logic channel and transmission channel mapping relations schematic diagram, and as shown in the figure, in current standard, the mapping relations of logic channel and transmission channel are:
In single cell transmission of MBMS, MTCH and MCCH are mapped on the DL-SCH;
In many cell transmission of MBMS, MTCH and MCCH are mapped on the MCH;
In the MBMS dedicated cell, MTCH and MCCH are mapped on MCH or the DL-SCH;
In the MBMS/ clean culture mixed cell, MTCH and MCCH are mapped on MCH or the DL-SCH.
The main effect of each channel is as follows:
BCCH is used for the broadcast system control information;
MTCH is used for sending the MBMS business datum by eNB to UE;
MCCH is used for sending the MBMS control information corresponding with one or more MTCH by eNB to UE.According in the definition in MBSFN zone as can be known, a sub-district in the MBSFN retaining zone scope can belong to a plurality of MBSFN zone, Fig. 2 is the overlapping situation schematic diagram in MBSFN sub-district, as shown in Figure 2, all comprises sub-district 4 in the MBSFN zone 1,2,3.
Therefore, not only to comprise the general-purpose control information of MBMS among the MCCH of MBSFN overlay cells (as: sub-district 4), also will comprise the information that the MBSFN transmission merges that is used at variant MBSFN zone, as: the schedule information of each corresponding MTCH in MBSFN zone.For this reason, designed the MCCH structure of layering in the prior art, Primary MCCH (one-level MCCH) and SecondaryMCCH (secondary MCCH) have been defined, Fig. 3 is the MCCH and the MBSFN regional relation schematic diagram one of each sub-district, Fig. 4 is the MCCH and the MBSFN regional relation schematic diagram two of each sub-district, as shown in the figure, comprise the control information commonly used of MBMS among the PrimaryMCCH (for being shown P-MCCH among the succinct figure), can also comprise in the schedule information, certain MBSFN zone of Secondary MCCH (being shown S-MCCH) and be used for the information such as information that MBSFN merges among the succinct figure.When being used for the information of MBSFN merging in comprising a MBSFN zone among the Primary MCCH, this Primary MCCH will participate in MBSFN transmission merging, situation as shown in Figure 3 in certain MBSFN zone; Otherwise Primary MCCH will not participate in concrete MBSFN transmission and merge, as shown in Figure 4 situation.
Among Fig. 3, not carrying any certain concrete MBSFN zone among the P-MCCH (one-level MCCH) is used for the information that the MBSFN transmission merges and (describes for simplifying, be called the not corresponding concrete MBSFN zone of P-MCCH), as: the MBMS schedule information of MTCH correspondence, only carry the schedule information of Secondary MCCH and the contents such as control information commonly used of MBMS, be used for the information that MBSFN transmission merges in each MBSFN zone and carry by the corresponding S-MCCH (secondary MCCH) in this MBSFN zone.Among Fig. 4, carry among the P-MCCH and be used for the information that MBSFN transmission merges in certain MBSFN zone, that is: P-MCCH is corresponding with certain MBSFN zone.
Secondary MCCH and concrete SFN (Single Frequency Network, Single Frequency Network) transmission region is corresponding, to carry the concrete MBMS business information of transmitting in the corresponding MBSFN zone, as: the pairing resource location of MTCH (subframe position and/or physical resource position) that carries professional particular content.Corresponding Secondary MCCH in each MBSFN zone (, so should the zone not needing corresponding Secondary MCCH in Primary MCCH) if the MBMS business information of transmitting in certain MBSFN zone is carried.
The associated description of MCCH structure in the current standard is as follows:
-BCCH carries the schedule information (may have two Primary MCCH, a MCCH is at the single cell transmission on the DL-SCH, and at the many cell transmission on the MCH) of Primary MCCH.If there is Secondary MCCH among the MCH, the Primary MCCH on the MCH can indicate the position of Secondary MCCH;
-BCCH only points to the resource that can find Primary MCCH, not the availability of display business;
-in a MBSFN zone, for single cell transmission, Primary MCCH sends on DL-SCH; For many cell transmission, Primary MCCH sends on MCH;
-overlapping MTCH-MBSFN zone can cause a plurality of MCCH.In this case, can utilize Secondary MCCH to distinguish different MBSFN zones.
MCH and DL-SCH all can be used for the MBMS transmission, but MCH supports MBSFN to merge, and DL-SCH does not support MBSFN to merge.
For many cell transmission of MBMS, a carrier frequency can be supported a plurality of MCH.Each MCH only comprises the data that belong to a MBSFN zone, but a MCH can carry a plurality of MBMS data.
The distribution of each MCH physical resource is by specifying a sub-frame pattern to realize for it, and each subframe that is comprised in time need not adjacent (this mode be called MCH sub-frame allocation pattern (MSAP)).Each MSAP that carries the MCH of MTCH is notified by MCCH.Comprising on the MCH of a plurality of MTCH, the order of transmission of each MTCH is also notified by MCCH.
In sum, in the current LTE standard, MBMS information transmitted indication process is as follows:
1, the BCCH indication can be used for the subframe position and the P-MCCH subframe position of MBSFN transmission;
2, in P-MCCH, read S-MCCH subframe position and other information (as: general information of MBMS);
3, in S-MCCH, read the MTCH information of carrying corresponding MBSFN area data.
By the definition in MBSFN zone as can be known, a MBSFN synchronized cells can belong to a plurality of MBSFN zone simultaneously.Because each MBSFN zone can corresponding S-MCCH, therefore, when a sub-district belongs to a plurality of MBSFN zone with a plurality of S-MCCH of correspondence.In addition, multiple MBMS business can be supported in each MBSFN zone, and every kind of business can be mapped on the different MTCH to be transmitted.The deficiencies in the prior art just are: though provided mapping relations between logic channel and transmission channel in the current standard, but the information relevant with the MBMS business tine (as: catalogue of business tine that MBMS provides) how to send to UE and how UE does not point out to corresponding MCCH and MTCH resource according to the relevant information searching with business tine that receives.

When implicit expression was related, the business tine relevant information is residing position or each business tine relevant information this professional MBSFN area identification of ordering implicit expression indication transmission in BCCH in BCCH, promptly the 3rd kind; Perhaps send the sign of the corresponding S-MCCH (or P-MCCH) in this professional MBSFN zone, promptly the 4th kind.
Two, carry out association by P-MCCH.
Carry the relevant information of business tine at BCCH, carry related information, then can comprise when related setting up at P-MCCH:
The information of the MCCH that the MBSFN zone of this business tine of acquisition transmission is corresponding;
According to the position of the P-MCCH that indicates among the BCCH, read the content among the P-MCCH;
MCCH in P-MCCH that the relevant information of business tine is corresponding with the MBSFN zone that sends this business tine is associated.
Under this mode, BCCH only carries the relevant information of business tine, as the business tine tabulation, and service identification (as: traffic ID number) etc.Obtain to send the position of the informational needs of the corresponding S-MCCH (or P-MCCH) in this professional MBSFN zone, read the content among the P-MCCH according to the P-MCCH that indicates among the BCCH.
Then MCCH (S-MCCH or P-MCCH) that the relevant information of business tine is corresponding with the MBSFN zone that sends this business tine can be in the following ways when being associated in P-MCCH:
1), the relevant information of business tine is left in the resource of corresponding MCCH position, MBSFN zone that the P-MCCH indication sends this business tine being distributed, the residing position of business tine relevant information is associated with the regional corresponding MCCH resource location of the MBSFN that sends this business tine.
Under this interrelational form, the business tine relevant information directly can be left in P-MCCH is to send in the resource of distributing this corresponding S-MCCH (or P-MCCH) position, professional MBSFN zone, according to the residing position of business tine relevant information, just know the resource location that sends the corresponding S-MCCH (or P-MCCH) in this professional MBSFN zone, concrete can be S-MCCH place subframe position, perhaps can also comprise the physical resource position in the subframe of S-MCCH (or P-MCCH) place.
2), with the related MBSFN zone corresponding identification that sends this business tine of the relevant information of business tine, this sign is associated with the regional corresponding MCCH resource location of the MBSFN of this business tine of transmission.
Under this interrelational form, related one of business tine relevant information can be sent this professional MBSFN zone corresponding identification (as: MBSFN area I D number); Can in P-MCCH, obtain to send the resource location of the corresponding S-MCCH (or P-MCCH) in this professional MBSFN zone by this sign, this resource location is specifically as follows S-MCCH place subframe position, can be subframe numbers, subframe deviation post or other are used to determine the parameter of relevant sub-frame position, perhaps can also comprise the physical resource position in the subframe of S-MCCH (or P-MCCH) place.
That is, in above-mentioned association process, the MCCH resource location can be S-MCCH place subframe position; The perhaps physical resource position in S-MCCH or the P-MCCH place subframe.
Wherein, subframe position can be for comprising the parameter that is used to determine the relevant sub-frame position of subframe numbers and/or subframe deviation post.
In order to allow the UE side can read the content of S-MCCH fast, can the S-MCCH resource location information in P-MCCH in concrete the enforcement comprise the physical resource position in S-MCCH place subframe position and the place subframe thereof by the S-MCCH resource location information among the P-MCCH.Describe with instantiation below.
Fig. 6 is a FDD wireless frame structure schematic diagram, and as shown in the figure, each radio frames length is 10ms, is made of 10 subframes, and the length of each subframe is 1ms.The control information of BCCH transmitting system is made of MIB (Master Information Block, Master Information Block) and SIB (System Information Block, system information block), SIB be divided into again SIB1, SIB2 ....Point out in the current standard to be used to transmit Master Information Block (MIB) and system information block 1 (SIB1), and subframe #0, the #4, #5 and the #9 that are used to the paging (Paging) carried out can not be used for the MBSFN transmission, other subframe all can be used for the MBSFN transmission.
If be used for indicating the information of MBSFN regional location and P-MCCH subframe position to carry in the SIB2 that subframe #6 transmits, the sub-frame configuration that then can be used for the MBSFN transmission is #2, #3, #7, #8.If there are two MBSFN zones in this sub-district, P-MCCH place subframe is #8, and then having the S-MCCH place subframe of MBSFN zone 1 correspondence is #8, and the S-MCCH place subframe of MBSFN zone 2 correspondences is #3 (that is: adopt situation shown in Figure 3).
If the information that business tine is relevant sends to the user by BCCH, business tine (relevant information) S-MCCH corresponding with sending this professional MBSFN zone that sends to UE undertaken related by P-MCCH, and in P-MCCH this professional MBSFN area I of a transmission of direct correlation D number after the business tine relevant information; Then in P-MCCH, can identify subframe position and the physical resource position of S-MCCH in this subframe that obtains to send corresponding S-MCCH place, this professional MBSFN zone by this.
Like this, after UE received the MBMS business datum, utilizing the indication of P-MCCH and S-MCCH to obtain the process of relevant information can be as follows:
1, UE is earlier by reading slot # 6 subframes that SIB1 (#5 subframe) finds SIB2;
2, in SIB 2, obtain the relevant information of the MBMS business tine that all subframe position information (#2, #3, #7, #8), P-MCCH subframe position (#8) and this sub-districts that can be used for MBSFN transmission send.
In the LTE system, the configuration of MBSFN being transmitted subframe position can be the cycle with 1 radio frames or 4 radio frames.Concrete which subframe is used for carrying out adopting the mode of bit mapping (bitmap) to indicate in the block of information that MBSFN is transmitted in system broadcast message in the radio frames.Because not all subframe can be configured to carry out the MBSFN transmission in the radio frames, so bit mapping (bitmap) only needs to indicate and get final product disposing the subframe of carrying out the MBSFN transmission.Fdd mode has 6 the configurable MBSFN of carrying out transmission of subframe, TDD (Time Division Duplex, time division duplex) 5 the configurable MBSFN of carrying out transmission of subframe is arranged, therefore, the length of bit mapping (bitmap) was 6 bit when configuration cycle was 1 radio frames, the length of bit mapping (bitmap) was 4*6=32 bit (annotate: because LTE system requirements FDD and TDD compatibility, therefore, the length of bit mapping (bitmap) all is unit with 6bit) when configuration cycle was 4 radio frames.
3, in SIB2, find the business tine information that needs after, subframe position according to the P-MCCH place of SIB2 indication, read the data on the P-MCCH, this professional MBSFN area I of transmission that is associated by required business tine relevant information D number obtains to send the subframe position and the physical resource position of S-MCCH in this subframe at corresponding S-MCCH place, this professional MBSFN zone.
4, read the S-MCCH that sends this professional MBSFN zone correspondence, in S-MCCH, read professional pairing MTCH information.
By said process as can be seen, comprise by the S-MCCH resource location information in P-MCCH and physical resource position in S-MCCH place subframe position and the place subframe thereof just can allow the UE side can read the content of S-MCCH fast by the S-MCCH resource location information among the P-MCCH.
Accordingly, when the S-MCCH resource location information in P-MCCH comprises physical resource position in S-MCCH place subframe position and the place subframe thereof, in following LTE system, certainly take this mode to read the content of S-MCCH fast in the reception processing scheme of information.
The MTCH information of Fig. 7 when comprising physical resource position in S-MCCH place subframe position and the place subframe thereof in resource location information reads schematic flow sheet, as shown in the figure, can comprise the steps:
Step 701, find SIB2 by SIB1;
Step 702, find the subframe position of P-MCCH by SIB2;
Step 703, obtain the resource location of S-MCCH by P-MCCH;
Step 704, in S-SCCH, read corresponding M TCH information.
Enforcement by the way, as can be seen the relevant information by setting up the MBMS business tine and send business tine the MBSFN zone, with the regional corresponding MCCH resource location three of MBSFN between related, just can be after sending the relevant information of described business tine to the user by BCCH or MCCH, make the UE side receiving the MBMS business tine, and the relevant MTCH information of this business tine.For this reason, also provide the receiving handling method of information in the LTE system in the embodiment of the invention, described below.
Fig. 8 is the receiving handling method implementing procedure schematic diagram of information in the LTE system, as shown in the figure, can comprise the steps: when message pick-up is handled
The relevant information of the business tine of the MBMS communication service that step 801, reception base station send;
Step 802, according to the relevant information of MBMS business tine and send the MBSFN zone, MBSFN zone of business tine and corresponding MCCH resource location three between relatedly determine the MCCH resource location;
Step 803, basis read business tine from the information that described MCCH resource location receives from MTCH.
It is corresponding that related when sending set up scheme, when receiving corresponding processing scheme arranged also, concrete, sets up related enforcement and see also and above-mentionedly carry out association and carry out association by P-MCCH by BCCH, below the processing execution mode that receives is introduced.
One, carrying out related reception by BCCH handles.
When relevant information that receives the business tine that the base station sends from BCCH and incidence relation, determine that then the MCCH resource location can comprise:
Determine P-MCCH resource location indicated among the BCCH;
In the P-MCCH resource location according to the relevant information of business tine determine this professional MBSFN of associated transmission zone or with the corresponding MCCH resource location in MBSFN zone.
