Description
Technical field
The present invention relates to field of wireless communication, particularly at TD-SCDMA (Time DivisionSynchronization Code Division Multiple Access, the TD SDMA access) in the system, the collocation method of MBMS (multimedia broadcast/multicast system) special carrier and data transmission method, method of reseptance.
Background technology
The MBMS special carrier technology of TD-SCDMA passes in 3GPP (third generation partner program) meeting, the MBMS business only is provided on this special carrier, the spectrum efficiency of MBMS has obtained raising under this structure, but this scheme is based on existing frame structure, be not suitable for bigger cell transmission, and spectrum efficiency neither be very high, and the frame structure of TD-SCDMA as shown in Figure 1.Requirement for the big cell networking that satisfies the MBMS of operator broadcasting, obtain higher spectrum efficiency, guarantee UE (user equipment, mobile subscriber equipment) the MBMS quality of service under the high-speed mobile, frame structure for TD-SCDMA improves at present, and this frame structure is applicable to the MBMS special carrier.
After having carried out simple improvement for frame structure shown in Figure 1, go for the MBMS special carrier, its main feature is: all time slots all are used for downlink transfer and do not have ascending time slot; 3 special time slot (protection between the uplink and downlink timeslot is GP at interval for descending pilot frequency time slot DwPTS, uplink pilot time slot UpPTS) free time do not send any data; Each common time slot still adopts midamble (intermediate code) to carry out channel estimating.
In order further to improve the spectrum efficiency of special carrier carrying MBMS business, frame structure for TD-SCMDA has carried out improving further, it mainly improves: 3 special time slots are merged into a crack (MBMS special burst in short-term, be called for short MS burst), be used to carry MBMS control signaling and system broadcast message etc., with other 7 common time slots (Time slot=0 ... 6, MBMStraffic burst is called for short MT burst) carrying MBMS business information; And adopt Preamble (lead code) to replace the Midamble sign indicating number and carry out channel estimating.At present, disclosed new improvement frame structure as shown in Figure 2, its main feature is:
(1) all time slots all are descending, all are used for downlink transfer;
(2) do not protect (GP) at interval between the time slot;
(3) there is not the switching point of uplink and downlink timeslot;
(4) 3 special time slots (protection between uplink pilot time slot, descending pilot frequency time slot and the up-downgoing at interval) are merged into a crack in short-term;
(5) on a TD-SCDMA subframe, comprise 7 common time slots and 1 crack in short-term;
(6) crack is used to carry sub-district public control signaling and system broadcast message and paging indication information etc. in short-term, comprise particularly: the control information of MBMS business, as: MCCH (MBMS control channel), MICH (MBMS indicating channel) etc., and system broadcast message etc.;
(7) common time slot is used to carry the Traffic Channel (MTCH, MBMS trafficchannel) of MBMS;
(8) adopt Preamble sign indicating number (lead code) to replace midamble (centre) sign indicating number and carry out channel estimating, be used for protection and isolation between time slot with CP (cyclic sequence) replacement GP.
Frame structure spectrum efficiency after the improvement is higher, also supports the big zone of MBMS business to cover.Frame structure after this improvement, the sub-district that only is used to carry the MBMS special carrier, the common time slot of all of this sub-district all is used to carry the MBMS business.In the present invention, sub-district on the MBMS special carrier is exactly MBSFN pattern (MBSFN mode:Transmission mode where a set of synchronizedcells transmit exactly the same data for provision of MBMS service, the MBMS business of transmission identical data in some synchronized cells) sub-district, the MBMS business is only carried in this sub-district.
The problem that exists is at present, many variations have taken place in the TD-SCDMA frame structure of the sub-district on the MBMS special carrier, channel estimating especially for each time slot adopts preamble sign indicating number rather than midamble sign indicating number, because scrambler and basic preamble are one to one each other, so each basic preamble sign indicating number sign and scrambler sign primordial this preamble sign indicating number and scrambler are to identifying, according to agreement TS25.223, as shown in table 1.
The mapping table of table 1, basic lead codes and scrambler
| Scrambling Code ID (scrambler sign) | Basic preamble Code ID (basic lead codes |
| ? | Sign) |
| 0? | 0? |
| 4? | 1? |

RNC can also for MBMS on carrier cell dedicated the basic preamble sign indicating number of each MS burst time slot configuration and scrambler to sign; Basic preamble sign indicating number that is disposed and scrambler also can be identical or different to sign.
B, RNC send the NBAP message of MBMS on carrier cell dedicated to Node B, set up request message or Common transport channel in described sub-district and set up that to carry RNC in the request message be that the basic preamble sign indicating number that disposed of the MT burst time slot of MBMS on carrier cell dedicated and scrambler are to sign; If RNC has been each MS burst time slot configuration basic preamble sign indicating number and scrambler to sign, also carries RNC in the then described NBAP message is that the basic preamble sign indicating number that disposed of MBMS each MS burst time slot on carrier cell dedicated and scrambler are to sign.Described NBAP message comprises that request message is set up in the sub-district, Common transport channel is set up request message etc.
After C, Node B received described NBAP message, Node B was that the carrier cell dedicated basic preamble sign indicating number of each MT burst time slot configuration of MBMS and scrambler are to sign according to described message; If also carry the basic preamble sign indicating number of promising each MS burst time slot configuration and scrambler in the described message, be that the carrier cell dedicated basic preamble sign indicating number of each MS burst time slot configuration of MBMS and scrambler are to sign also then according to described message to sign.
If the sub-district set up do not carry in the request message into the basic preamble sign indicating number of certain time slot configuration and scrambler to sign, then this time slot of Node B adopts the basic preamble sign indicating number of a time slot and scrambler to sign; If a described last time slot does not dispose basic lead codes and scrambler to sign yet, then adopt the basic lead codes that goes up a time slot again and scrambler to sign, by that analogy at this time slot.If Common transport channel set up do not carry in the request message into the basic preamble sign indicating number of certain time slot configuration and scrambler to sign, then Node B adopts the basic preamble sign indicating number of original configuration and scrambler to sign at this time slot.Time slot described here is a MT burst time slot, does not comprise MS burst time slot.
D, RNC send the MBMS business datum, and Node B, carries described MBMS business datum and gives UE sign according to basic preamble sign indicating number that current time slots disposed and scrambler.
The present invention also provides a kind of MBMS data receive method on carrier cell dedicated, is applied to may further comprise the steps in the TD-SCDMA system:
A, RNC be MBMS on carrier cell dedicated the basic preamble sign indicating number of MT burst time slot configuration and scrambler to sign; Described basic preamble sign indicating number and scrambler be to being used to indicate a pair of basic preamble sign indicating number and scrambler, can but be not limited to a numerical value; Basic preamble sign indicating number that is disposed and scrambler can be identical or different to sign.
B, RNC send MBMS on carrier cell dedicated system broadcast message or RRC message to UE, in described system broadcast message, carry RNC and be basic preamble sign indicating number that the MTburst time slot of MBMS on carrier cell dedicated disposed and scrambler to sign.Described system broadcast message comprises system broadcast message 5, and described RRC message comprises that the point that is carried on the MCCH channel is to the multiple spot control messages.
After c, UE receive described system broadcast message, according to the RNC that wherein carries is that basic preamble sign indicating number and the scrambler that the MT burst time slot of MBMS on carrier cell dedicated disposed receives the MBMS business datum to sign, be exactly specifically: according to the basic preamble sign indicating number and the scrambler of message authentication current time slots employing, to extract the preamble sign indicating number in the time slot, finish the decoding of MBMS business datum then in conjunction with scrambler; The same prior art of process of extracting and decoding.
If do not carry in system broadcast message or the RRC message into the basic preamble sign indicating number of certain time slot configuration and scrambler to sign, then the preamble sign indicating number and the scrambler of UE time slot on this time slot adopts are right, if a last time slot does not dispose basic lead codes and scrambler to sign yet, then UE adopts the basic lead codes that goes up a time slot again and scrambler to sign, by that analogy at this time slot.
Further be illustrated with an application example of the present invention below.
On the interface (Iub interface) of RNC and Node B, as shown in Figure 4, the sub-district that sends to Node B by RNC in the NBAP agreement (application protocol of Node B) sets up request message (CELLSETUP REQUEST) and Common transport channel is set up request message (COMMON TRANSPORTCHANNEL SETUP REQUEST), RNC be the identical or different basic preamble sign indicating number of each carrier cell dedicated time slot configuration of the MBMS of Node B and scrambler to sign (each basic preamble sign indicating number and scrambler to the scrambler in the sign and substantially the preambel sign indicating number be unique correspondence).
Wherein the preamble sign indicating number on MS burst (crack in short-term) is a preset parameter value that all MBMS dedicated cells are identical with scrambler.
Wherein the preamble sign indicating number on each MT burst (common time slot) is identical to being configured to scrambler, also can be configured to different.
Set up in the request message in the sub-district, RNC need for each MT burst (7 altogether, time-gap number 0～6) all dispose the preamble sign indicating number and scrambler right.And in the practical application, RNC may not all not dispose the preamble sign indicating number for each MT burst and scrambler right; If RNC does not dispose preamble sign indicating number for certain MT burst and scrambler is right, then the preamble sign indicating number of this time slot and scrambler are right to the preamble sign indicating number and the scrambler that adopt previous numbering configuration, as: time-gap number 0 do not dispose the preamble sign indicating number and scrambler right, then time-gap number 0 adopts the preamble sign indicating number and the scrambler of time-gap number 7 right, if time-gap number 7 is not configuration also, then time-gap number 0 adopts time-gap number 6, and the like, for another example: time-gap number 3 do not dispose the preamble sign indicating number and scrambler right, it is right that then this time slot adopts the preamble sign indicating number and the scrambler of time-gap number 2, if it is right that time-gap number 2 does not dispose preamble sign indicating number and scrambler yet, then adopt the preamble sign indicating number and the scrambler of time-gap number 1 right.
Set up in the request message at Common transport channel, RNC can be (7 altogether of part or all of MT burst, time-gap number 0～6) basic preamble sign indicating number of configuration and scrambler are to sign, when RNC not for certain MT burst configuration preamble sign indicating number and scrambler during to sign, then this MT burst adopts the basic preamble sign indicating number of original configuration and scrambler to sign.Should with RNC in the example do not dispose the preamble sign indicating number for MS burst and scrambler right.
After Node B received above-mentioned message from RNC, fixing basic preamble sign indicating number of configuration and scrambler were to sign on MS burst, and identical or different basic preamble sign indicating number of configuration and scrambler are to sign on 7 MT burst.
On the eating dishes without rice or wine of RNC and UE on (Uu interface), as shown in Figure 5, send to system broadcast message 5 (SIB 5) or the RRC message of MBMS in carrier cell dedicated by RRC agreement (radio resource control) as: RNC, for the identical or different basic preamble sign indicating number of descending MT burst (common time slot) configuration of MBMS on carrier cell dedicated and scrambler to sign (every pair basic preamble sign indicating number corresponding one by one to scrambler), and basic preamble sign indicating number on the MS burst on the MBMS special carrier (crack in short-term) and scrambler do not need configuration to sign, adopt the fixed value of default configuration, network side (comprising RNC and Node B) and UE are known in advance, and the MS burst of all sub-districts on the MBMS special carrier adopts this identical fixed value.
Wherein, among the SIB 5 or RRC message that on MBMS is carrier cell dedicated, sends, need comprise basic preamble sign indicating number and scrambler the configuration to identify of RNC to each MT burst (7 altogether, time-gap number 0～6).And in the practical application, RNC may not all not dispose the preamble sign indicating number for each MT burst and scrambler right; If do not dispose basic preamble sign indicating number and scrambler to sign among the SIB5 for certain MT burst, then the basic preamble sign indicating number of this time slot and scrambler adopt the basic preamble sign indicating number of previous numbering configuration and scrambler to sign to sign, do not dispose basic preamble sign indicating number and scrambler to sign as: time-gap number 0, then the basic preamble sign indicating number of time-gap number 0 employing time-gap number 7 and scrambler are to sign, if time-gap number 7 is not configuration also, then time-gap number 0 adopts time-gap number 6, by that analogy.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the present invention.
