Description
Technical field
The present invention relates generally to Wideband Code Division Multiple Access (WCDMA) (WCDMA), relates in particular to sending method, method of reseptance and the realization equipment thereof of multimedia broadcast multi-broadcasting business in the WCDMA system (MBMS).
Background technology
MBMS, the evolution as WCDMA strengthens broadcasting service defines in the protocol version of 3GPP Release 6.It provides, and a data source realizes that Internet resources are shared, raising Internet resources, especially utilization ratio of wireless resources to the point-to-multipoint service that a plurality of users send data from wireless network.MBMS has realized the broadcasting and the multicast of high-speed multimedia business, makes the ip multicast data can put the transmission of multiple spot in wireless access network.
In order to obtain the optimal transmission of MBMS bearer service in wireless access network (RAN), 3GPP in RAN standard multinomial technology, as put multiple spot (p-t-m) transmission, 1/ selectivity merges (L1/Selective combining) and transformat selection (between p-t-m and the p-t-p (point-to-point)).
Point can allow all users that customize same MBMS business at a transmission channel to multiple spot (p-t-m) transmission---and forward access channel (FACH) is gone up the identical data of reception.In the WCDMA system, transmission channel FACH is mapped on inferior-Common Control Physical Channel (S-CCPCH).Usually, physical channel can multiplexing a plurality of transmission channels, when two or more MBMS business hours is multiplexed on the single S-CCPCH channel, just need radio network controller (RNC) to carry out MBMS Traffic Channel (MTCH) scheduling, dispatch these MBMS business and go up transmission at arranged Transmission Time Interval (TTI).The different delivery times of MTCH schedule information (MTCH Scheduling Information) record different business, and utilize special channel---MTCH scheduling channel (MSCH) is mapped in and sends to subscriber equipment (UE) on the same S-CCPCH channel.After UE receives the MSCH Frame, can carry out discontinuous reception (DRx) to this S-CCPCH channel, and can carry out the soft merging of part (partial soft combining) according to the MTCH schedule information according to the MTCH schedule information.
According to the result that current standard is discussed, for each scheduling interval, periodically the MSCH that sends comprises the information that following needs transmit at each business:
-MBMS service identification;
The duration of-the zero hour and transfer of data.
Follow such rule, Fig. 1 has provided MTCH scheduling and the multiplexing example of S-CCPCH in the prior art.
In this example, as shown in Figure 1, (40msTTI) provides three kinds of business on the S-CCPCH channel of a 64kbps:
A 32kbps business (MBMS business 1),
A variable bit rate business, tolerable 640ms postpones (MBMS business 2),
A low rate traffic is allowed very big delay (MBMS business 3),
The every 640ms of schedule information provides once, and as shown in fig. 1, its system-frame number (SFN) is 255,319 etc.Form institute record among the content of schedule information such as Fig. 2 in this example.
By this form as can be seen, be positioned at SFN and be 255 schedule information and represent that be that SFN is 256 frame the zero hour of MBMS business 1, its duration is 32 frames.If user is only interested in MBMS professional 1, then after SFN 255 receives above-mentioned schedule information, beginning at interval (256, receive the data of MBMS business 1 in 256+32).
Receive next MBMS scheduling message at SFN 319, SFN is that 319 schedule information represents that be that SFN is 320 frame the zero hour of MBMS business 1, and its duration is 32 frames.
Afterwards, this user is 319 schedule information reception subsequent frame again according to SFN.Reception and said process to other business and schedule information thereof are similar.
In the meeting of 3GPP about MBMS, wireless access network working group (RAN 1) has agreed that hypothetical layer 1 merges under (soft merging) prerequisite, and UE must be able to be incorporated in the transmission link from different districts in the 2TTI+1 time slots window.That is to say that UE can carry out the synchronization time difference of two links of soft merging must be within the 1TTI+1 time slot.
Fig. 3 has provided the example of the time difference of a professional transmission of different districts MBMS, in this example, is selected to carry out soft merging, selectivity merging or mix to merge by UE.
In this example, the pane of grey is the TTI transmission block of a 40ms, and representative sends identical MBMS data on the S-CCPCH of different districts channel.Can see that the time difference of neighbor cell 3 surpasses the 1TTI+1 time slot, and neighbor cell 1 and neighbor cell 2 and Serving cell is synchronous in the receiver window of UE.Therefore, the UE of Serving cell can select the S-CCPCH channel of neighbor cell 1 or neighbor cell 2 to carry out soft merging, perhaps can select the S-CCPCH channel of neighbor cell 3 to carry out the selectivity merging.In addition, if the ability of UE permission can also all receive the S-CCPCH channel of each neighbor cell and does to mix and merge.
At the scheduling and the synchronous situation of above-mentioned Serving cell, neighbor cell 1, neighbor cell 2 and neighbor cell 3, the schematic diagram that UE receiver execution selectivity merges and mixing merges as shown in Figure 4.In the selectivity of Fig. 4 A merges, the soft bit of Serving cell is stored and decoded with a Turbo decoder, the soft bit of neighbor cell 3 is stored and decoded with the 2nd Turbo decoder, again both are carried out selectivity and merge.In the mixing of Fig. 4 B merges, store and decode with the bit of a Turbo decoder after the soft merging of Serving cell and neighbor cell 2, the soft bit of neighbor cell 3 is stored and decoded with the 2nd Turbo decoder, again the selectivity merging is carried out in storage and decoded result.
Can see that from top description existing MTCH channel dispatch technology is with on a plurality of MBMS service integration to a physical channel, and the message of MSCH channel bearing can be so that the user carries out discontinuous reception.But under the definition of existing MSCH schedule information, in each dispatching cycle, a MBMS business can only send in flakes continuously, as shown in Figure 1.Therefore, though the user can receive discontinuously, thereby when not receiving data, close receiver to save energy, but, when the user receives data, receiver must have very big one memory headroom to store many soft symbols that receive branch, and receiver must dispose two or more Turbo decoders simultaneously, as shown in Figure 4.
Though the ability of definition UE must be able to support selectivity to merge and soft merging in protocol specification, but, when having three links all good signal to noise ratio to be arranged, UE can can't implement to mix the selectivity merging of merging or three branch roads because of limited ability, and the idle moment of wait is gone processing because UE does not have enough internal memories that the soft bit of bulk is left.

The present invention also provides the MBMS among a kind of RNC professional transmitting apparatus, is used to carry out MBMS method for transmitting service of the present invention.According to the structural representation of the professional transmitting apparatus 800 of MBMS of the present invention as shown in Figure 8, it comprises and disperses schedule information creation apparatus 801, mapping device 802 and dispensing device 803.Wherein, disperse schedule information creation apparatus 801 to disperse schedule information according to MBMS service creation waiting for transmission, this dispersion schedule information comprises transmission block information at interval.Mapping device 802 is according to the dispersion schedule information of disperseing schedule information creation apparatus 801 to create, finish MSCH and MTCH mapping to S-CCPCH, make the professional ground interlaced with each other of each MBMS, and respectively with the form of transmission block, be mapped on time Common Control Physical Channel according to the interval of transmission block interval information indication.The mapping of finishing according to mapping device 802 sends to UE by S-CCPCH with signal by dispensing device 803.
The present invention also provides a kind of MBMS service reception equipment of UE end, is used to receive the signal that sends according to MBMS method for transmitting service of the present invention.According to the structural representation of MBMS service reception equipment 900 of the present invention as shown in Figure 9, it comprises that receiving system 901 and decoding merge device 902.Wherein, receive the signal that sends through S-CCPCH, and read dispersion schedule information wherein by receiving system 901.This dispersion schedule information comprises the duration and the transmission block information at interval of MBMS service identification, the zero hour and transfer of data.Afterwards, receiving system 901 disperses schedule information at required business according to these, respectively in each transmission block interval, receive with the merging mode corresponding district branch road of determining on a transmission block corresponding at interval with this transmission block, and the transmission block that receives sent into the merging device 902 of decoding successively.Decoding merges the transmission block of 902 pairs of inputs of device or merges after the transmission block after the soft merging is decoded again, and the result is exported.
The schematic diagram that the transmission block that carries out in the above-mentioned receiver merges as shown in figure 10, wherein, Figure 10 A represents the schematic diagram that selectivity merges, Figure 10 B represents to mix the schematic diagram of merging.In the present embodiment, be that example describes to receive MBMS professional 1 still, wherein also have three neighbor cells except that the service sub-district, and the time difference of transmitting between these four sub-districts as shown in Figure 3, transmission block is spaced apart 3TTI.
Shown in Figure 10 A, when carrying out the selectivity merging, because transmission block is spaced apart 3TTI, receiving system 901 is after receiving the MSCH sign thus, in first transmission block interval, first transmission block corresponding to MBMS business 1 in receiving Serving cell, also utilize transmission block blanking time reception of neighboring cell 3 corresponding to first transmission block of MBMS business 1, and carry out the selectivity merging again after will above-mentioned two transmission blocks sending into the Turbo decoder successively and decoding.After the merging of this first transmission block is finished dealing with, again in second transmission block interval, receive in the Serving cell corresponding in second transmission block of MBMS business 1 and the neighbor cell 3 corresponding to second transmission block of MBMS business 1, carry out selectivity again after sending into the Turbo decoder successively and decoding and merge.Carry out follow-up reception, decoding and merging by that analogy.
Similarly, mixing for Figure 10 B merges, also be in transmission block 3TTI at interval, receive the corresponding transmission block of Serving cell and corresponding neighbor cell respectively, after soft merging is finished, to send into the Turbo decoder decode successively through the transmission block on the sub-district branch road of transmission block after the soft merging and time difference overtime window, and mix merging afterwards again, and the follow-up corresponding transmission block of reception is decoded and merged in the transmission block interval of back.
Though UE can bump when receiving different branch datas, also not receive such as a TTI data block, another data that merge branch arrive, and this collision only needs the very little metadata cache of receiver just can solve.In the definition of 25.302 pairs of UE abilities of 3GPP TS, stipulated that a UE can support to receive simultaneously and surpassed one S-CCPCH channel on same Frequency point.Thereby UE can be when receiving soft mergings branch, and the 1TTI data block of receiver selectivity merging branch also is placed in the TTI buffer memory.In case the Turbo decoder discharges from the decoding of soft merging branch data, data in buffer just can be right after see processed.For example the selectivity to continuous transmission shown in Figure 3 merges and the mixing merging, only needs the soft symbol values spatial cache of 1TTI and 1 Turbo decoder to get final product.
Find out thus, after implementing above-mentioned dispersion scheduling transmission, the processing of UE receiver just can be as pipelining, receive earlier this sub-district branch data (comprise soft merging after data), deliver to the Turbo decoder decode, branch data that again can reception of neighboring cell 1 in blanking time is delivered to the Turbo decoder decode.If blanking time long enough, branch data that then can also reception of neighboring cell 2 is delivered to the Turbo decoder decode.Therefore, MBMS method for transmitting service of the present invention can just can be implemented to mix the selectivity merging of merging or three branch roads as extra internal memory and Turbo decoder, thereby obtain bigger receiving gain so that UE does not need extra ability.
