Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
See Fig. 1, be the schematic flow sheet of the pilot frequency collocation method based on shared community of the first embodiment provided by the invention, the method comprises:
Step S100: encode to the information of carrying on shared control channel HS-SCCH, generates the shared control channel HS-SCCH carrying phase reference instruction;
Particularly, network side can design HS-SCCH channel, by encoding to the information of carrying on shared control channel HS-SCCH, generates the shared control channel HS-SCCH carrying phase reference instruction; The instruction of this phase reference can comprise launch point mark or pilot channel mark.The corresponding launch point sending described public guide frequency of described launch point mark; The corresponding pilot channel sharing community of described pilot channel mark.In the present embodiment, the shared control channel HS-SCCH carrying phase reference instruction namely carries the instruction of described phase reference by the information of this HS-SCCH channel.Carry out coding to the information of carrying on shared control channel HS-SCCH can be considered to encode to shared control channel HS-SCCH.
Again particularly, a LPN launch point can launch a Common Pilot Channel separately, namely a Common Pilot Channel is just corresponding with a launch point.But in order to reduce the number of Common Pilot Channel as far as possible, reduce code channel and take number, two or more LPN launch points can not overlapping each other (namely non-conterminous) in coverage send identical Common Pilot Channel; At this moment which launch point UE can distinguish this Common Pilot Channel from when receiving, and only needs to distinguish pilot channel and identifies.
Step S102: send pilot configuration information to subscriber equipment by the shared control channel HS-SCCH of described generation, described phase reference indicates the phase reference being used for determining high-speed physical downlink shared channel (HS-PDSCH) HS-PDSCH by described subscriber equipment.
Particularly, when described phase reference is designated as launch point mark, described subscriber equipment can determine public guide frequency that launch point the sends phase reference as high-speed physical downlink shared channel (HS-PDSCH) HS-PDSCH according to described launch point mark;
When described phase reference is designated as pilot channel mark, described subscriber equipment can determine the phase reference of pilot channel as high-speed physical downlink shared channel (HS-PDSCH) HS-PDSCH of the shared community that described pilot channel mark is corresponding.
It should be noted that, the Common Pilot Channel in the embodiment of the present invention includes but not limited to demodulation pilot frequency D-CPICH.
Particularly, the schematic flow sheet that the embodiment of the present invention as shown in Figure 2 is encoded to HS-SCCH, comprising:
Step S200: obtain phase reference instruction and customer equipment identification;
Step S202: carry out assembly coding to described phase reference instruction and described customer equipment identification, generates combination mark;
Step S204: carry out shared control channel HS-SCCH coding according to described combination mark.
Particularly, the cyclic redundancy check (CRC) that the embodiment of the present invention can carry out shared control channel HS-SCCH according to described combination mark adds; Or add according to the user equipment (UE) that described combination mark carries out shared control channel HS-SCCH and cover.Be designated as launch point with phase reference below and be designated example, point above-mentioned two situations are described in detail:
A, carry out CRC interpolation:
Particularly, the control information bit x on the first time slot is inputted 1,1, x 1,2..., x 1,8, the control information bit x on second and third time slot 2,1, x 2,2..., x 2,13, by following 6 step algorithms:
1) by x 1,1, x 1,2..., x 1,8, x 2,1, x 2,2..., x 2,13obtain CRC check bit p im1, p im2..., p im16.
2）[c 1c 2... c 16]=[p im16p im15... p im1]
3）[y 1... y 13]=[x 2,1... x 2,13]
4）x ue,tx,k=x ue,kfor k=1,2,...16-n
5）x ue,tx,k=(x ue,k+x tx,k-16+n)mod2for k=17-n,...15,16
6）y k=(x ue,tx,k-13+c k-13)mod2for k=14,15...29

It should be noted that, because UE mark and launch point mark are all network side configurations, therefore net the uniqueness that side needs to ensure combination mark in combined cell community, thus avoid confusion.
B, carry out UE and add and cover:
Particularly, the coded bit r of the control information on first time slot is inputted 1,1, r 1,2... r isosorbide-5-Nitrae 0, by following 5 step algorithms:
A) x ue, 1, x ue, 2..., x ue, 16through 1/2 convolution code, obtain b i, i=1,2..., 48.
B) b i, i=1,2..., 48 destroy b 1, b 2, b 4, b 8, b 42, b 45, b 47, b 48, obtain c 1, c 2... .c 40.
c)c tx,k=c kfor k=1,2,...40-n
d)c tx,k=(c k+x tx,k-40+n)mod2for k=41-n,...39,40
e)s 1,k=(r 1,k+c tx,k)mod2for k=1,2...40

Understandably, UE can also be carried out by 5 step algorithms below to add and cover:
a)x ue,tx,k=x ue,kfor k=1,2,...16-n
b)x ue,tx,k=(x ue,k+x tx,k-16+n)mod2for k=17-n,...15,16
C) x ue, tx, 1, x ue, tx, 2..., x ue, tx, 16through 1/2 convolution code, obtain b i, i=1,2..., 48
D) b i, i=1,2..., 48 destroy b 1, b 2, b 4, b 8, b 42, b 45, b 47, b 48, obtain c 1, c 2... .c 40
