Description
Technical field
The present invention relates to Wideband CDMA Technology, code channel resource using method and equipment in particularly a kind of broadband CDMA system.
Background technology
It is the important technology that developed recently gets up in Wideband Code Division Multiple Access (WCDMA) (WCDMA, the Wideband Code Division Multiple Address) communication system that the high-speed downstream bag inserts (HSDPA, High Speed Downlink Packet Access).Than R99 technology before this, three physical channels have been increased in the HSDPA technology newly, that is: High-Speed Shared Control Channel (HS-SCCH, High Speed Shared Control Channel), high-speed downstream Physical Shared Channel (HS-PDSCH, High Speed Physical Downlink SharedChannel) and high-speed dedicated control channel (HS-DPCCH, High Speed Dedicated ControlChannel).
Wherein, HS-SCCH and HS-PDSCH are two down channels.The HS-SCCH channel is used for communicating control information, comprise user terminal (UE, User Equipment) information such as ID, modulation system, new data indication, transmission block size and HS-PDSCH channel code collection, (SF SpreadingFactor) is fixed as 128 to the spreading factor of this channel.The HS-PDSCH channel be the service surface data after handling through coding and rate-matched etc., the SF of this channel is fixed as 16.UE need utilize the service surface data of the control information on the HS-SCCH channel on could the correct HS-PDSCH of reception channel.
In the HSDPA technology, channel code is an important downlink resource.Base station controller (RNC, Radio Network Controller) reshuffles signaling (PHYSICAL SHAREDCHANNEL RECONFIGURATION REQUEST) by Physical Shared Channel and issue request, set up DSCH Downlink Shared Channel HS-SCCH and HS-PDSCH to the NodeB side.The concrete form that Physical Shared Channel is reshuffled signaling please refer to the related description in existing 3rd Generation Partnership Project (3GPP, Third Generation Partnership Project) technical specification (TS) 25.433 agreements.
RNC reshuffles signaling by Physical Shared Channel, specifies one of NodeB side to support in the sub-district of HSPDA the channel code which SF the HS-SCCH channel can use equal 128, and the channel code of specifying the HS-PDSCH channel can use which SF to equal 16.And the channel code that is assigned to HS-SCCH and HS-PDSCH channel can not be used by other R99 channel or other HSDPA channel again.
In realizing process of the present invention, the inventor finds that there are the following problems at least in the prior art:
In the HSDPA technology, when UE inserts the NodeB rear flank, at a transmission time interval (TTI, Transmission Time Interval) in, the NodeB side is if send data to UE, need use some HS-PDSCH code channels according to the size that sends data volume, use a HS-SCCH code channel simultaneously.In actual applications, the HS-SCCH channel code occurs through regular meeting and can not satisfy the UE demand, cause the problem of HS-PDSCH code channel resource waste simultaneously.
Illustrate: RNC has promptly disposed 4 HS-SCCH code channels for the NodeB side has disposed 4 channel code, 15 HS-PDCH code channels, but current needs provide the HSDPA UE of service to have 10.Because the HS-SCCH code channel number is less than the UE number, these 10 UE just can only obtain service in turn.When these 10 UE are to delay requirement during than higher and UE that volume of transmitted data is less, during as ip voice business (VoIP, Voice Over IP) UE, the service quality that will occur causing because HS-SCCH channel yardage is limited descends.And meanwhile, because the data volume of VoIP class business is all smaller, so, in each TTI, each UE may only need a HS-PDSCH code channel can satisfy the requirement that its data transmits, thereby causes 11 HS-PDSCH code channel resources to be wasted.

Embodiment
In the embodiment of the present invention,, propose a kind of channel code and share scheme for solving the problems of the prior art.Change in the prior art the fixedly way of HS-SCCH and HS-PDSCH channel code number, when permission can not satisfy the demands at the code channel resource as HS-SCCH, one in the HS-PDSCH channel code of configuration or part are split into the HS-SCCH channel code, utilize the HS-SCCH code channel that splits the HS-SCCH channel code generation that obtains that UE is dispatched, thereby improve the code channel resource utilance in the HSDPA technology, and provide better service quality for UE.
Because the SF of HS-SCCH channel is 128, the SF of HS-PDSCH channel is 16, so a HS-PDSCH sign indicating number can be split as 8 HS-SCCH channel code.Concrete fractionation mode is known in this field, repeats no more.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing embodiment that develops simultaneously, the present invention is described in further detail.
Fig. 1 is the flow chart of the inventive method first embodiment.As shown in Figure 1, may further comprise the steps:
Step 101:NodeB side determines that the code channel resource of current HS-SCCH can not satisfy the demands, and the HS-PDSCH channel code that disposes is split as the HS-SCCH channel code.
Before this step, further comprise: RNC is NodeB side X HS-SCCH channel code of configuration and Y+1 HS-PDSCH channel code, and wherein, the initial code Taoist monastic name of Y+1 HS-PDSCH channel code is N.0＜N＜16, and 0＜(Y+N)＜=16.The concrete configuration mode is a prior art, repeats no more.
RNC is for after the NodeB side configures HS-SCCH channel code and HS-PDSCH channel code, the UE that the request of receiving of NodeB side joint inserts.For the UE of new access, the NodeB side can be distributed available HS-SCCH channel code for it, comprises the HS-SCCH channel code of being distributed by RNC and the HS-SCCH channel code that can obtain by fractionation.In the subsequent process, whether UE monitors the NodeB side and utilizes a certain code channel wherein to send control information to it on the HS-SCCH code channel of the HS-SCCH channel code correspondence of being distributed, after monitoring and receiving the control information of NodeB side transmission, can determine corresponding HS-PDSCH according to the information such as HS-PDSCH channel code collection of wherein carrying, and and then obtain business datum from HS-PDSCH.Usually, UE can only monitor 4 HS-SCCH code channels at most simultaneously.
In this process, the NodeB side is can may in fact not existing by the HS-SCCH channel code that fractionation obtains of UE distribution, because when the NodeB side is distributed the HS-SCCH channel code at the UE that is new access, may can also satisfy the demands owing to current HS-SCCH code channel resource, so also do not carry out the fractionation of HS-PDSCH channel code.But self can know the NodeB side in advance, can obtain which HS-SCCH channel code if split, so, can in advance it be distributed to UE.But in actual applications, can or can not use the HS-SCCH channel code that splits gained on earth, also need to be determined on a case-by-case basis.In the subsequent process, the code channel of the available HS-SCCH channel code correspondence that the NodeB side can be by distributing to UE sends control information to UE, promptly UE is dispatched.
Along with constantly there being UE to add, the a certain moment, the UE quantity of going into when the NodeB side joint, then needs to obtain required HS-SCCH channel code by splitting the HS-PDSCH channel code that is disposed, to satisfy ever-increasing UE demand during for the HS-SCCH channel code number X of its configuration greater than RNC.Specific implementation can be: the NodeB side is split as eight HS-SCCH channel code with RNC respectively for last M channel code in Y+1 the HS-PDSCH channel code of its configuration.Wherein M can be one or more.
Specifically needing to split what HS-PDSCH channel code need be determined according to self by the NodeB lateral root, such as, the NodeB side can be known the number of the UE that needs to provide service in self scope in advance, can determine that according to this information what HS-PDSCH channel code needs split and could probably meet the demands.Certainly, also can determine according to other known condition.But the NodeB side is in case after determining to need to split what HS-PDSCH channel code, during follow-up the fractionation, will carry out practical operation according to this quantity of determining.
Step 102: use the HS-SCCH code channel that splits the HS-SCCH channel code correspondence that obtains that UE is dispatched.
In this step, in line with the preferential principle of using the HS-SCCH channel code of distributing by RNC, when the NodeB side uses the HS-SCCH code channel that splits the HS-SCCH channel code correspondence that obtains that UE is dispatched at needs, at first judge in advance in the available HS-SCCH channel code for the UE distribution, whether have in the code channel of the HS-SCCH channel code correspondence of distributing by RNC and to be in idle state, if have, then utilize this code channel that UE is dispatched; If no, then use the code channel that splits gained channel code correspondence in the available HS-SCCH channel code of distributing as UE, UE is dispatched.When utilizing the HS-SCCH code channel that UE is dispatched, the NodeB side utilizes the code channel that is not used more than in the HS-DPSCH code channel to send business datum to UE according to the incremental order of sign indicating number Taoist monastic name from N to N+Y-M.That is to say, suppose that the HS-DPSCH code channel of sign indicating number Taoist monastic name from N+5 to N+Y-M all is not used, so, in this step, the NodeB side can be according to the size of data volume to be sent, use the code channel of sign indicating number Taoist monastic name as N+5, and perhaps the sign indicating number Taoist monastic name is that the code channel of N+5, N+6...... sends business datum to UE.
Along with continuous use, the quantity of available HS-DPSCH channel code can be fewer and feweri.When not having the HS-DPSCH channel code,, also can't transmit information to UE even also have available HS-SCCH channel code.So, before this step, also will further may further comprise the steps, that is, the NodeB side determines whether there is the code channel that is not used in the Y-M+1 from N to N+Y-M HS-DPSCH code channel of sign indicating number Taoist monastic name, if having, ability execution in step 102.
In the subsequent process, along with part UE winding-up withdraws from the NodeB side, the a certain moment, the UE quantity that inserts the NodeB side may be less than or equal to the HS-SCCH channel yardage of being distributed by RNC, in this case, the NodeB side can be reassembled into the HS-PDSCH channel code with each the HS-SCCH channel code that splits gained, and uses according to normal HS-PDSCH channel code.How to be combined as prior art, to repeat no more.
As seen, adopt the technical scheme of the embodiment of the invention,, realized that code channel resource shares, thereby improved the code channel resource utilance, and provide better service quality for UE by fractionation and combination to the HS-PDSCH channel code.
Below by other specific embodiment, scheme of the present invention is described in further detail:
Fig. 2 is the flow chart of the inventive method second embodiment.Among this embodiment, when the HS-SCCH channel code of distributing as RNC can not satisfy the demands, the NodeB side only split in the HS-PDSCH channel code of being distributed last.As shown in Figure 2, may further comprise the steps:
Step 201:RNC is NodeB side configuration HS-SCCH channel code and HS-PDSCH channel code.
In this step, RNC is carrying out Physical Shared Channel when reshuffling, and is x HS-SCCH channel code of NodeB side configuration, and yard Taoist monastic name of corresponding SF=128 is A1, A2......, Ax.In the present embodiment, will be called special-purpose HS-SCCH channel code, abbreviate private code as by the HS-SCCH channel code of RNC configuration.
Simultaneously, RNC is y+1 HS-PDSCH channel code of NodeB side configuration, and the sign indicating number Taoist monastic name of wherein initial HS-PDSCH channel code is n, promptly, the sign indicating number Taoist monastic name of SF=16 of this y+1 HS-PDSCH channel code correspondence be n, n+1, n+2 ..., n+y, wherein 0＜n＜16 and 0＜(y+n)＜=16.
Step 202:NodeB side is distributed available HS-SCCH channel code for the UE that inserts.
In this step, in the process that connects for the new UE that inserts, the NodeB side is that UE distributes available HS-SCCH channel code, specific implementation is: from private code with split and to choose num and 4-num channel code the HS-SCCH channel code of gained respectively and distribute to UE, num=MIN (x, 3) wherein.The front was introduced, and a UE can only monitor 4 HS-SCCH code channels at most simultaneously, so in this enforcement, when the channel code of choosing from private code was num, the channel code number of selecting from share sign indicating number just can only be 4-num.Need to prove, be 4 to describe with the HS-SCCH code channel number only in the present embodiment, in actual applications, can also be as required UE HS-SCCH code channel number of monitoring simultaneously be set to other value, such as 2,3 etc.
Be example with x=2 below, illustrate in the present embodiment how to be the available HS-SCCH channel code of UE distribution, B1～B8 wherein represents to split the HS-SCCH channel code of gained.
Table one HS-SCCH channel code allocation example
| The user | The HS-SCCH channel code of distributing | ? |
| UE1 | A1、A2 | B1、B2 |
| UE2 | A1、A2 | B3、B4 |
| UE3 | A1、A2 | B5、B6 |
| UE4 | A1、A2 | B7、B8 |
| UE5 | A1、A2 | B1、B2 |
| UE6 | A1、A2 | B3、B4 |
| UE7 | A1、A2 | B5、B6 |
| UE8 | A1、A2 | B7、B8 |
| UE9 | A1、A2 | B1、B2 |
| UE10 | A1、A2 | B3、B4 |
| ...... | ...... | ...... |
As shown in Table 1, the HS-SCCH channel code of distributing for each UE is formed by channel code two parts of private code and fractionation gained.In table one example shown, A1 and A2 are distributed to each UE, and different UE according to insert order assignment to fractionation gained channel code be respectively B1, B2, B3, B4, B5, B6 ....
In this step, the NodeB side is can may in fact not existing by the HS-SCCH channel code that splits gained of UE distribution, because when the NodeB side is distributed the HS-SCCH channel code at the UE that is new access, because current HS-SCCH code channel resource can also satisfy the demands, so also do not carry out the fractionation of HS-PDSCH channel code.But self can know the NodeB side in advance, can obtain which HS-SCCH channel code if split, so, can in advance it be distributed to UE.Each UE monitors own 4 corresponding HS-SCCH code channels respectively according to the method for salary distribution shown in the table one.
Step 203:NodeB side judges whether the UE quantity that inserts is less than or equal to x, if then execution in step 204; Otherwise, execution in step 205.
In present embodiment, judge exactly whether the UE quantity that inserts is less than or equal to 2.
Step 204:NodeB side uses the code channel of private code correspondence that UE is dispatched, and after this step finishes, returns execution in step 203.
In this step,, then can use the code channel of A1 or A2 correspondence that this UE is dispatched if the actual UE that inserts the NodeB side has only one.If the actual UE that inserts the NodeB side has two, then can use the code channel of A1 correspondence that UE1 is dispatched, use the code channel of A2 correspondence that UE2 is dispatched, perhaps, use the code channel of A1 correspondence that UE2 is dispatched, use the code channel of A2 correspondence that UE1 is dispatched.
Step 205:NodeB side is split as 8 HS-SCCH channel code with last HS-PDSCH channel code.
Along with constantly there being new UE to insert the NodeB side, because a UE need use a HS-SCCH code channel, so a certain moment, the HS-SCCH private code can not satisfy the UE demand.In this case, just need be with last M HS-PDSCH channel code, M is one in the present embodiment, is about to last HS-PDSCH channel code and is split as 8 HS-SCCH channel code, i.e. B1～B8.As shown in Figure 3, Fig. 3 is that the HS-PDSCH channel code splits the mode schematic diagram in the embodiment of the invention.Because B1～B8 can use with the HS-SCCH Channel Sharing,, be called for short and share sign indicating number so it is referred to as to share the HS-SCCH channel code.So, available HS-SCCH channel code has just become x+8, i.e. a private code A1～Ax and a shared sign indicating number B1～B8.
In the said process, because the SF of HS-SCCH channel is 128, the SF of HS-PDSCH channel is 16, so a HS-PDSCH sign indicating number can be split as 8 HS-SCCH channel code.Concrete fractionation mode is known in this field, repeats no more.
Step 206:NodeB side is used the HS-SCCH private code and is shared sign indicating number UE is dispatched.
In this step, the NodeB side uses the shared sign indicating number of original HS-SCCH private code and fractionation gained that UE is dispatched, and specific implementation comprises:
The preferential private code that uses the sign indicating number Taoist monastic name as A1, A2, promptly working as need be to a certain UE, when UE3 dispatches as shown in Table 1, at first judge in the available HS-SCCH channel code of UE3 correspondence, whether the code channel of A1 or A2 correspondence is idle, if then use this free time code channel that UE3 is dispatched; Otherwise, use the code channel of B5 or B6 correspondence that UE3 is dispatched.When using the HS-SCCH code channel that UE3 is dispatched, also need by the HS-PDSCH code channel to the UE3 transmit traffic data.The using priciple of HS-PDSCH code channel is in the embodiment of the invention: use according to the incremental order from initial code Taoist monastic name n to n+y, guarantee that promptly n+y bar code channel is used at last.
After having dispatched UE3, if also have residue in the HS-PDSCH code channel of sign indicating number Taoist monastic name from n to n+y-1, promptly be not used in addition, so then can continue to use and share other UE of sign indicating number scheduling, such as UE4; After having dispatched UE4, if also have residue in the HS-PDSCH code channel of sign indicating number Taoist monastic name from n to n+y-1, then can continue to dispatch UE5, and the like, all finish using up to the HS-PDSCH code channel of sign indicating number Taoist monastic name from n to n+y-1, perhaps all HS-SCCH code channels all are used and finish.
Illustrate: Fig. 4 is channel code occupation mode schematic diagram in the embodiment of the invention.As shown in Figure 4:
Wherein, figure A represents to use the scheduling code channel UE1 of private code A1 correspondence, promptly to the UE1 communicating control information, uses simultaneously yard Taoist monastic name as the HS-PDSCH code channel of n, n+1 and n+2 to the UE1 transmit traffic data.
Figure B represents to use the scheduling code channel UE2 of private code A2 correspondence, uses simultaneously yard Taoist monastic name as the HS-PDSCH code channel of n+3 and n+4 to the UE2 transmit traffic data.
Figure C represents, after dispatch UE1 and UE2, use to share yard scheduling code channel UE3 of B5 correspondence, use simultaneously yard Taoist monastic name as the HS-PDSCH code channel of n+5 and n+6 to the UE3 transmit traffic data.
Scheme D and represent, use a scheduling code channel UE4 who shares sign indicating number B7 correspondence, use the sign indicating number Taoist monastic name to arrive the HS-PDSCH code channel of n+y-1 to the UE4 transmit traffic data simultaneously as n+7.So far, owing to being used, the HS-PDSCH code channel finishes, so process ends.
Based on said method, Fig. 5 is the composition structural representation of present device embodiment.As shown in Figure 5, this equipment comprises: split cells and transmitting element;
