Embodiment
Referring to Fig. 3, under ofdm system, the assumed wireless resource comprise 30 fundamental frequency resources and 6 basic time resource, one of them fundamental frequency resource is 16 subcarriers, 1 basic time resource be 1 OFDM symbol, then this part Radio Resource is the rectangle of 30 fundamental frequency resource * 6 resource basic time.This part resource is called physical radio resource, also is physical resource.Handle in order to simplify top signaling, we will set up a logic Radio Resource of this part physical resource, also be logical resource, also be the rectangles by 30 fundamental frequency resource * 6 resource basic time.And the mapping mode of two kinds of logical resources to physical resource arranged, comprise DRCH mapping or BRCH mapping.
BRCH and DRCH can adopt two kinds of multiplex modes to be mapped to physical resource, and first kind takies different sub-bands for DRCH respectively with BRCH, and non-overlapping copies is referring to Fig. 4; Second kind is disperseed in whole frequency band for DRCH, and BRCH uses DRCH to take the remaining physical resource in back then, referring to Fig. 5.
As shown in Figure 6, in the present embodiment this part Radio Resource is divided into a public control section, take 2 fundamental frequency resource * 6 resource basic time, 28 remaining fundamental frequency resources are divided into 4 equal-sized zones, and each zone takies 7 fundamental frequency resource * 6 resource basic time.
Wherein public control section comprise in have:
1). the resource mapping method that adopt in each zone.
Comprise DRCH or BRCH.1 bit is used in each zone, so need 4 * 1=4 bit altogether.
2) what control channels each zone has.
The control channel of each terminal is a control channel resource in this zone, can stipulate that each zone can only have 3 control channels at most, and each zone is represented with 2 bits, so need the indication of 4 * 2=8 bit control channel number.
3) modulation or the coded system of each control channel in each zone.
The coded system that can stipulate each control channel is all identical, different just modulation systems, for example comprise QPSK or 16QAM, because each zone has 3 control channels at most, each control channel has only two kinds of modulation systems, so each zone needs 3 bits, need 4 * 3=12 bit altogether.The coded system that can certainly stipulate each control channel can be different with modulation system, just will cause the indication information of presentation code and modulation system of being used for of needs to increase like this, increase the expense of public control section.
Include control channel and data channel in described each zone, wherein control channel can be arranged on the place that each area dividing begins, and a plurality of control channels are by elder generation's time sequence arrangement of frequency again, each control channel takies 1 fundamental frequency resource * 3 resource basic time, the data channel of control channel in the one's respective area in can the assignment one's respective area, untapped resource in also can the public control section of assignment, the data channel in can also other zone of assignment.Different resource mapping method can be used in each zone, also can use identical resource mapping method, and the resource mapping method that use in each zone is by public control section indication.
Continuation is referring to Fig. 6, and the embodiment of the invention supports each zone to adopt different resource mapping method, and for example the mode of DRCH is adopted in zone 1 and zone 2, and the mode of BRCH is adopted in zone 3 and zone 4.
Which type of resource mapping method concrete certain zone adopts to be determined by base station each band channel quality information according to terminal to report.
For example, the channel quality indication of terminal to report oneself on this 4 sub-frequency bands, if it is all high more a lot of than the channel quality on other sub-bands at the channel quality on certain sub-frequency bands that terminal is found in the base station, and be higher than a threshold value, (this threshold value can be set in advance), the base station just can judge that the resource mapping method of this terminal use BRCH is better so, and knows that the channel quality of terminal on which zone is best; If the base station finds that the channel quality of terminal on 4 sub-frequency bands that report is all similar, the resource mapping method of this terminal use DRCH just can be judged in the base station so.This sub-district is calculated in the base station, and all need the optimum resource mapping method of the terminal of scheduling resource, then according to the quantity of the terminal of using DRCH and BRCH and the resource size of needs, and terminal is optimum on which frequency band when using BRCH, decided what DRCH and BRCH and when use BRCH which terminal should be placed on which BRCH zone.3 terminals are for example arranged at the 3rd sub-frequency bands upper signal channel optimal quality, the base station just can become BRCH with the 3rd area dividing so; Have 2 terminals to use the DRCH optimums, so the base station just can the 1st or the 2nd or the 4th zone be set to DRCH and give this 2 terminals uses.
Another method is exactly that terminal is to the optimum resource mapping method of base station feedback oneself, and when using BRCH at that regional channel quality optimum, the base station can be adopted as top method and be calculated DRCH zone and the BRCH zone number that needs then, and which zone uses DRCH and which zone to use BRCH.
Then the data channel of terminal and control channel preferably all are placed on the zone of selected best resource mapping method,, the control channel of this terminal can be put into other zone so if control channel that should the zone is piled.
By this method, can make the good terminal of frequency diversity gain use the resource mapping method of DRCH, make the resource mapping method of the terminal use BRCH that it is good that frequency selectivity gains, and adopt this method can make the control channel of terminal and data channel adopt identical mapping mode, to avoid making certain user's control channel and data channel performance difference bigger.
Fig. 7 is a kind of control channel indication of embodiment of the invention current region schematic diagram, wherein, and data 1 and data 2 in the control 1 in zone 1 and the control 2 difference assignment one's respective areas 1; Data 1 in the control 1 assignment one's respective area 2 in the zone 2; The zone in 3 control 1, control 2 and control 3 data 1, data 2 and data 3 in the assignment one's respective areas 3 respectively; Zone 4 does not have control channel.
Fig. 8 is the transregional indication schematic diagram in a kind of control channel of embodiment of the invention territory, and wherein the resource assignation of the control channel in zone 1, zone 2 and the zone 3 all is in the intra-zone assignment, and is identical with top description.And the data channel signal 2 in the control channel of zone in 4 zone 2 of having controlled 1 assignment has been represented the method for this trans-regional assignment.This trans-regional assigning method mainly is used in to work as and uses certain regional user many, but because the restriction of control channel number, and can only put into other zone to the control channel of this area data channel of this assignment.
In addition, control channel in each zone also can be by the first frequency arrangement mode of time again, for example the regulation control channel on time resource, fixedly take 1 basic time resource, and take 3 fundamental frequency resources on the frequency, the position that just is mapped to sub-band with top difference is different.
Also have, control channel also can use the arrangement mode of space division multiple access, is about on the different layer that a plurality of control channels are arranged in space division multiple access, and terminal need be resolved one's own control channel on the different layers at identical running time-frequency resource when resolving.Data channel can adopt identical space division multiple access mode with control channel.
Each regional control channel can also comprise the position of the data channel that is used to refer to terminal, and whether the modulation coding mode of data channel continues assignment, whether increment assignment, and the information of whether using multi-antenna technology etc.
The embodiment of the invention provides control channel of two kinds of method indications to belong to which terminal or a plurality of terminal.
Method one, the base station comprises user totem information in each control channel that sends, be public to identify this control channel, one group of user's still unique user.Terminal then identifies according to this judges whether own needs of certain control channel.
Method two, the base station does not comprise user totem information in each control channel that sends, but increase a cyclic redundancy code in each control channel information back, the scrambler of knowing in advance with known or one group of user is to the cyclic redundancy code scrambling of control channel and increase then, make each or one group of terminal can both resolve control channel this broadcasting or multicast like this, thereby solve the information that broadcast data or multi-case data need allow these users receive with the acquisition system.The cyclic redundancy code of each control channel and increase also can use the sign of the independent prior distribution of each user to carry out scrambling, this control channel just has only this user can and check whether CRC correctly judges whether oneself by descrambling like this, thereby obtain the control information of oneself, other user then abandons the control channel that this can not correctly be resolved.
Be that each user's control channel is also encoded separately as a control channel in embodiments of the present invention, each user resolves these control channels to judge whether one's own control channel then.Can certainly use another method to finish same function, just in a zone, a plurality of users' control channel combined coding is become a control channel piece, the identification information that each user is arranged in this control channel, and also has the information that comprises in the above-mentioned control channel, to notify the user how resolution data channel.The user resolves the The whole control block of channels, to find one's own control information.
So when user's control channel adopted independent coding, the just corresponding control channel piece of each control channel then just had a plurality of control channel pieces this moment; And when user's control channel adopts combined coding, just having only a control channel piece, this control channel piece has comprised a plurality of users' control channel.
In addition, the resource in all right public control section of assignment of the control channel in each zone in residual resource or other zone, these needs increase public control section resource assignation sign in control channel or other area identification gets final product.
