Description

Method, base station and the subscriber equipment of transfer pre-coding control indication information

Technical field

The present invention relates to the communications field, and more specifically, relate to method, base station and the subscriber equipment of transfer pre-coding control indication information in the communications field.

Background technology

Develop rapidly along with the communication technology, Wideband Code Division Multiple Access (WCDMA) (Wideband Code Division Multiple Access, WCDMA) as one of mainstream technology of 3-G (Generation Three mobile communication system), broad research and application have been obtained in the world, WCDMA has had the 99th version (Release99 at present, R99), the 4th version (Release4, R4)～a plurality of versions such as the 10th version (Release10, R10).

In sixth version this (Release6, R6), introduced F-DPCH (Fractional Dedicated Physical Channel, fractional dedicated physical channel).F-DPCH is a kind of special descending DPCCH (Dedicated Physical Control Channel, Dedicated Physical Control Channel), is used for carrying TPC (Transmission Power Control, transmitting power control) order.Comprise time slot #0 to 15 time slots of time slot #14 in a F-DPCH frame, time slot has corresponding time slot format, can distinguish different subscriber equipmenies by time slot format, and a certain subscriber equipment is corresponding preallocated a kind of time slot format on F-DPCH.

The time slot format of F-DPCH is as shown in table 1, one of them time slot comprises 20 bits that are comprised of NOFF1 bit, TPC bit and NOFF2 bit, the NOFF1 bit is the side-play amount that is represented the position of TPC bit in a time slot by standard definition, and the NOFF2 bit is to satisfy the required additional bit of 20 bit lengths by standard definition.Network side is by distributing the time slot format numbering to come the time slot format that uses at F-DPCH to subscriber equipment and this subscriber equipment of base station assigns, thereby can determine the quantity of the NOFF1 bit, TPC bit and the NOFF2 bit that send in time slot and the symbol that takies.Because 2 bits are modulated onto on 1 symbol, so corresponding 10 symbols of time slot.As can be seen from Table 1, no matter in which kind of time slot format, the TPC bit number is 2 all, takies a symbol.

Table 1

In addition, along with the development of WCDMA business, the user constantly promotes the demand of WCDMA network performance.In order further to improve up covering and uplink transmission rate, introduced Closed-Loop Transmit Diversity (Closed Loop Transmit Diversity, CLTD) technology.

When after up link is introduced CLTD, precoding control indication (Pre-coding Control Indication need to be fed back to subscriber equipment in the base station, PCI) information, so that subscriber equipment is determined pre-coding matrix according to the PCI information of feedback, and carry out pre-encode operation, thereby the block length that subscriber equipment maximization existing channel condition is supported.No matter be that double fluid or single current send, because inferior pre-coding matrix that subscriber equipment can choice for use is unique definite function of main pre-coding matrix, so main pre-coding matrix can be fed back to subscriber equipment in the base station

Because the weight factor of first antenna of main pre-coding matrix

It is constant

The weight factor of second antenna

Can from following set, select, be specially which value, can be indicated by the PCI information of encoding with 2 bit code books:

$\left\{\begin{array}{cccc}\frac{1+j}{2}& \frac{1-j}{2}& \frac{-1+j}{2}& \frac{-1-j}{2}\end{array}\right\}$

At present, after up link is introduced CLTD, substantially determined in down link with F-PCICH (Fractional Precoding Control Indication Channel, part precoding control indicating channel) feedback PCI information, user that it must receives the PCI information of 2 bits could upgrade pre-coding matrix.Owing on F-PCICH, distinguishing the different user terminals of supporting CLTD with time slot format, therefore under different time slot formats, the timing that sends PCI information at F-PCICH also can be distinguished to some extent, so that the PCI information of feedback can be used in the uplink physical channel subframe timely by subscriber equipment.But, in the prior art, also do not provide the mechanism of base station to subscriber equipment feedback PCI information.

Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme of the embodiment of the invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiment.Based on the described embodiment among the present invention, the every other embodiment that those skilled in the art obtain under the prerequisite of not making creative work should belong to the scope of protection of the invention.

At first, in conjunction with the method 100 of Fig. 1 description according to the transmission PCI information of the embodiment of the invention.

As shown in Figure 1, method 100 comprises: in S110, obtain the frame shifting amount of F-PCICH; In S120, take timeslot number on the F-PCICH according to the time slot format of the F-PCICH of update cycle of PCI information, subscriber equipment and PCI information, determine the first time slot sequence number collection of carrying PCI information, and the character position that in a time slot, takies of definite PCI information, wherein, described PCI information is corresponding with a pre-coding matrix; In S130, send the F-PCICH frame according to frame shifting amount and time slot format to subscriber equipment, in time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number in character position carrying PCI information.

For example, method 100 can be carried out by the base station.When subscriber equipment was supported CLTD, the base station need to be by F-PCICH to subscriber equipment feedback PCI information.By said method, can realize the timing of PCI information in F-PCICH.By according to time slot format, take the first time slot sequence number collection that timeslot number, update cycle are determined carrying PCI information, be conducive to subscriber equipment after the F-PCICH frame extracts PCI information, at the pre-coding matrix corresponding to initial boundary use PCI information of uplink physical channel subframe.Below, describe the S110 to S130 according to the embodiment of the invention in detail.

In S110, the frame shifting amount of F-PCICH can be for fiducial time.Determining of fiducial time can be with P-CCPCH (Primary Common Control Physical Channel, Primary Common Control Physical Channel) original position is as the reference time point of other channels, the frame shifting amount of other channels defines with the skew with respect to the original position of P-CCPCH, can be other modes, the present invention limit yet.

The base station can be passed through equipment of the core network (for example, the radio network controller) signaling that issues and determine the frame shifting amount of F-PCICH, also can determine by being arranged in advance computation rule in the base station frame shifting amount of F-PCICH, and this will be described in more detail below.

In S120, the time slot format of the F-PCICH of subscriber equipment can pre-determine.For example, the time slot format of F-DPCH that can be as shown in table 1 is such, design in advance the time slot format of F-PCICH, different time slot formats can be distinguished different subscriber equipmenies, and then selects a time slot format for a certain subscriber equipment from designed time slot format.For instance, equipment of the core network can be simultaneously to base station and subscriber equipment sending time slots form numbering, time slot format corresponding to this subscriber equipment to notify.

Time slot format can comprise the first sets of bits and the first sets of bits second sets of bits before of carrying PCI information.

Can comprise a plurality of bits in the first sets of bits.For example, if identical dibit of symbols carry in a time slot, then when PCI information took a symbol in a time slot, the first sets of bits contained 2 bits, when PCI information took two symbols in a time slot, the first sets of bits contained 4 bits.Because the codebook size of PCI information is 2 bits, so PCI information can take at most 2 symbols in a time slot.For example, when the timeslot number that takies when PCI information was 1, PCI information took 2 symbols in the time slot of carrying PCI information; When the timeslot number that takies when PCI information was 2, PCI information took 1 symbol in each time slot of carrying PCI information.

A plurality of bits can be comprised in the second sets of bits, also any bit can be do not comprised.When the second sets of bits included bit, each bit in the second sets of bits can be specific bit, also can be VB vacancy bit, and so-called VB vacancy bit represents to reserve the position of bit but do not have actual bit to exist.Bit number in the second sets of bits can represent the side-play amount of the first sets of bits in a time slot.

Time slot format also may comprise the first sets of bits the 3rd sets of bits afterwards except comprising the first sets of bits and the second sets of bits.The bit number that the 3rd sets of bits can be used for a time slot is comprised satisfies the required total number of bits of time slot.When the total number of bits that comprises when the second sets of bits and the first sets of bits equaled bit number that a time slot requires, the 3rd sets of bits did not comprise any bit.When the 3rd sets of bits included bit, each bit in the 3rd sets of bits can be specific bit, also can be VB vacancy bit.

For example, the time slot format of F-PCICH can comprise the second sets of bits, the first sets of bits and the 3rd sets of bits successively.The second sets of bits can have the form such as the NOFF1 bit in the time slot format of F-DPCH; The first sets of bits is carried PCI information, may carry complete PCI information by the first sets of bits in the time slot, also may be carried by the first sets of bits in the time slot PCI information of part, complete PCI information represents to obtain the PCI information that pre-coding matrix is required; The 3rd sets of bits can have the form such as the NOFF2 bit in the time slot format of F-DPCH, when the sum of bit in the second sets of bits and the first sets of bits satisfies the total number of bits of a time slot requirement, the 3rd sets of bits in the time slot format does not comprise any bit, and namely the bit number in the 3rd sets of bits is 0.

The timeslot number that the corresponding pre-coding matrix of PCI information, PCI information take on the F-PCICH can preset, also can be by equipment of the core network to base station and subscriber equipment dynamic assignment.According to embodiments of the invention, when the PCI information corresponding with pre-coding matrix was transmitted at least two time slots, PCI information took continuous time slot.When PCI information was transmitted at least two time slots, the time slot that PCI information takies may be arranged in same F-PCICH frame, and also possibility part time slot is positioned at the afterbody of a F-PCICH frame, and the part time slot is positioned at the head of next F-PCICH frame.No matter whether PCI information takies the time slot in the same F-PCICH frame, the time slot sequence number that the first time slot sequence number of determining in S120 is concentrated is PCI information time slot sequence number that the actual time slot that takies is corresponding in the F-PCICH frame, F-PCICH frame herein may be a F-PCICH frame, also may be to relate to two F-PCICH frames in the time slot situation of two F-PCICH frames in PCI information.

The update cycle of PCI information can characterize the transmission frequency of PCI information.The base station periodically sends PCI information according to the update cycle, the corresponding pre-coding matrix of the PCI information that sends in each update cycle.According to embodiments of the invention, a F-PCICH frame can be comprised of the F-PCICH subframe, and a F-PCICH subframe comprises 3 time slots, and a uplink physical channel subframe comprises 3 time slots, therefore the update cycle can be 3 time slots.

The time slot sequence number that the first time slot sequence number is concentrated may be the time slot sequence number in the same F-PCICH frame, also may be the time slot sequence number in the adjacent F-PCICH frame.The complete PCI information of time slot carrying that the time slot sequence number that the first time slot sequence number is concentrated is corresponding.Subscriber equipment can be brought into use pre-coding matrix corresponding to this PCI information at the initial boundary of uplink physical channel subframe extract PCI information from time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number after.The uplink physical channel subframe can comprise (the E-DCH Dedicated Physical Control Channel such as the subframe in the lower channel: E-DPCCH, the E-DCH Dedicated Physical Control Channel), E-DPDCH (E-DCH Dedicated Physical Data Channel, the E-DCH Dedicated Physical Data Channel), DPDCH (Dedicated Physical Data Channel, Dedicated Physical Data Channel), DPCCH (Dedicated Physical Control Channel, Dedicated Physical Data Channel), S-DPCCH (Second Dedicated Physical Control Channel, the second Dedicated Physical Control Channel).

The character position that PCI information takies in a time slot is relevant with time slot format.For example, after the time slot form comprises the second sets of bits and the second sets of bits carry the first sets of bits of PCI information the time, the character position that PCI information takies is immediately following after the character position that the second sets of bits takies, that is to say, the character position that the character position that PCI information takies and the second sets of bits take is adjacent and after the character position that the second sets of bits takies.

Although S120 carries out after S110 in method 100, it doesn't matter if S120 determines the first time slot sequence number and frame shifting amount, and S120 also can carry out before S110 so, can also carry out simultaneously with S110.

In S130, the base station is passed through with reference to time slot format, and according to the first time slot sequence number collection that carries PCI information, can generate the F-PCICH frame, and the frame shifting amount according to F-PCICH sends the F-PCICH frame again.Like this, subscriber equipment can extract PCI information according to time slot format, timeslot number, update cycle and the frame shifting amount identical with the base station from the F-PCICH frame that receives.After subscriber equipment extracted PCI information, the initial boundary of first uplink physical channel subframe that can send after receiving PCI information used the pre-coding matrix corresponding with PCI information.

For example, when hope will in time be used on the uplink physical channel by the PCI information of F-PCICH feedback, can configure the particular kind of relationship between the frame shifting amount of the frame shifting amount of F-PCICH and F-DPCH or descending DPCH, subscriber equipment can be used for E-DPCCH, E-DPDCH, DPCCH, the S-DPCCH etc. that up link be alignd in time with the PCI information by the F-PCICH feedback.Like this, subscriber equipment can be on the channels such as E-DPCCH, E-DPDCH, DPCCH, S-DPCCH the initial boundary of subframe, in time use the pre-coding matrix corresponding with PCI information, be conducive to like this shorten and receive that PCI information is to the time-delay of using between the PCI information, enhanced uplink data is to the speed-adaptive of channel condition, thereby improves systematic function.

According to embodiments of the invention, can according to the time slot format of the F-PCICH of update cycle of PCI information, subscriber equipment, PCI information take on the F-PCICH timeslot number and based on the Connection Frame Number of frame shifting amount, determine the second time slot sequence number collection of carrying PCI information in F-PCICH frame corresponding to Connection Frame Number, and the character position that in a time slot, takies of definite PCI information, the second time slot sequence number collection is the subset of the first time slot sequence number collection.

Time slot format, timeslot number, update cycle are identical with the explanation among the S120.

(Connection Frame Number, CFN) is identical with definition of the prior art for Connection Frame Number, can equal (SFN-frame shifting amount) mod 256, and wherein SFN is System Frame Number (System Frame Number, SFN).For F-PCICH, the CFN of F-PCICH frame can equal (frame shifting amount of SFN-F-PCICH) mod 256.Therefore, according to the frame shifting amount of the F-PCICH that in S110, obtains, can obtain the CFN of F-PCICH frame.

Can obtain in the following way the second time slot sequence number collection of carrying PCI information in F-PCICH frame corresponding to specific CFN.Easy for what describe, represent the timeslot number that the PCI information corresponding with pre-coding matrix takies with n, use N _Off1Represent the bit number in the second sets of bits, pass through N _Off1Can indicate the side-play amount of the first sets of bits in a time slot of carrying PCI information:

(A) determine in F-PCICH frame corresponding to CFN the time slot sequence number i of first time slot of carrying PCI information:

When n is 1, if N _Off1Be 0, then the time slot sequence number i of first time slot satisfies:

(15*CFN+i)modPCI_Update_cycle＝0 (1)

If N _Off1Greater than 0, then the time slot sequence number i of first time slot satisfies:

(15*CFN+i+1)modPCI_Update_cycle＝0 (2)

When n is 2, if N _Off1Be 0 or 2, then the time slot sequence number i of first time slot satisfies:

(15*CFN+i+1)modPCI_Update_cycle＝0 (3)

If N _Off1Greater than 2, then the time slot sequence number i of first time slot satisfies:

(15*CFN+i+2)modPCI_Update_cycle＝0 (4)

When n is 3, if N _Off1Be 0 or 2, then the time slot sequence number i of first time slot satisfies:

(15*CFN+i+2)modPCI_Update_cycle＝0 (5)

If N _Off1Greater than 2, then the time slot sequence number i of first time slot satisfies:

(15*CFN+i+3)modPCI_Update_cycle＝0 (6)

Wherein, a F-PCICH frame comprises 15 time slots of time slot sequence number from 0 to 14, and PCI_Update_cycle is the update cycle of PCI information.When the update cycle of PCI information was 3 time slots, this can save the 15*CFN in the expression formula (1) to (6).

(B) then, determine the second time slot sequence number collection of carrying PCI information in F-PCICH frame corresponding to CFN:

Owing to having determined the time slot sequence number of first time slot of carrying PCI information in previous step, in conjunction with the timeslot number that PCI information takies, can determine the second time slot sequence number collection.Particularly, when time slot corresponding to several time slot sequence numbers of continuous slot that the time slot sequence number from first time slot begins is all F-PCICH frame corresponding to CFN, several time slot sequence numbers of continuous slot that the second time slot sequence number collection begins for the time slot sequence number from first time slot; When time slot corresponding to several time slot sequence numbers of continuous slot that the time slot sequence number from first time slot begins was not all F-PCICH frame corresponding to CFN, the second time slot sequence number collection was last the time slot sequence number from the time slot sequence number of first time slot to this F-PCICH frame.

By above-mentioned (A) and (B), can determine the second time slot sequence number collection.

When the element number of the second time slot sequence number collection equals timeslot number, send F-PCICH frame corresponding to Connection Frame Number according to frame shifting amount and time slot format to subscriber equipment, in time slot corresponding to the time slot sequence number of concentrating with the second time slot sequence number in character position carrying PCI information.

If the element number of the second time slot sequence number collection equals timeslot number, then explanation can be carried complete PCI information this moment in F-PCICH frame corresponding to CFN, and the second time slot sequence number collection is exactly the first time slot sequence number collection.In this case, the F-PCICH frame that sends in S130 is F-PCICH frame corresponding to CFN.

When the element number of the second time slot sequence number collection during than the little N of timeslot number, send the next F-PCICH frame of F-PCICH frame corresponding to Connection Frame Number and this F-PCICH frame according to frame shifting amount and time slot format to subscriber equipment, in a beginning N time slot of time slot corresponding to the time slot sequence number of concentrating with the second time slot sequence number and next F-PCICH frame, carry PCI information at character position.

If the element number of the second time slot sequence number collection is less than timeslot number, then explanation can not be carried complete PCI information this moment in F-PCICH frame corresponding to CFN, the second time slot sequence number collection is less than the first time slot sequence number collection, need a beginning N time slot of F-PCICH frame corresponding to CFN to come together to carry complete PCI information with the corresponding time slot of time slot sequence number that the second time slot sequence number is concentrated, wherein N is the poor of the element number of the second time slot sequence number collection and timeslot number.In this case, the F-PCICH frame that sends in S130 is the next F-PCICH frame of F-PCICH frame corresponding to CFN and this F-PCICH frame.

According to one embodiment of present invention, if time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number is not in the pressing mold state, then in time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number in character position carrying PCI information; If arbitrary time slot is in the pressing mold state in time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number, then in time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number, do not carry described PCI information at character position.

May be owing to the restriction of resource, power etc., so that time slot is in the pressing mold state.When time slot is in the pressing mold state, do not send any information at this time slot.Therefore, in the time need to carrying PCI information in time slot corresponding to the time slot sequence number that the first time slot sequence number that S120 determines is concentrated, the time slot of carrying PCI information needs not to be in the pressing mold state, so just transmits a complete PCI information.If have any time slot to be in the pressing mold state in time slot corresponding to the time slot sequence number that the first time slot sequence number that S120 determines is concentrated, even remaining time slots is not in the pressing mold state, remaining time slots is not carried PCI information yet.For example, if the first time slot sequence number collection that S120 determines is 2 and 3, then be in the pressing mold state and the time slot of time slot sequence number 2 correspondences when not being in the pressing mold state when the time slot of time slot sequence number 3 correspondences, do not carry the PCI information in time slot sequence number 2 and 3.Again for example, if the first time slot sequence number collection that S120 determines is the time slot sequence number 14 of a F-PCICH frame and the time slot sequence number 0 of next F-PCICH frame, then be in the pressing mold state and the time slot of this time slot sequence number 0 correspondence when not being in the pressing mold state when the time slot of these time slot sequence number 14 correspondences, carrying PCI information in the time slot of this time slot sequence number 14 and this time slot sequence number 0.

Owing to concentrating in the situation that has time slot corresponding to time slot sequence number to be in the pressing mold state in the first time slot sequence number, not carrying out the transmission of PCI information, therefore can reduce descending interference.In addition, because the first time slot sequence number that subscriber equipment can not receive under the pressing mold state is concentrated time slot corresponding to time slot sequence number, therefore can reduce the power loss of subscriber equipment.

The method of the transmission PCI information that provides according to the embodiment of the invention, by sending PCI information according to frame shifting amount, time slot format, timeslot number and update cycle, can realize the channel of F-PCICH transmission PCI information regularly, thereby be convenient to the base station to subscriber equipment feedback PCI information, and be conducive to subscriber equipment in time upgrades needs use at the initial boundary of uplink physical channel subframe after receiving PCI information pre-coding matrix, thereby be conducive to improve upstream data to the speed-adaptive of channel condition, improve systematic function.

Next, the method 200 of describing according to the transmission PCI information of the embodiment of the invention with reference to figure 2.

In S210, obtain the frame shifting amount of F-PCICH, the frame shifting amount of F-PCICH equals the frame shifting amount of fractional dedicated physical channel (F-DPCH) or the frame shifting amount of downward special physical channel (DPCH).

Because equipment of the core network can be to the frame shifting amount of base station and notification of user equipment F-DPCH or the frame shifting amount of descending DPCH, the frame shifting amount of F-DPCH or the frame shifting amount of descending DPCH also are the side-play amounts with respect to the original position of P-CCPCH, so the base station by obtaining F-DPCH frame shifting amount or the frame shifting amount of descending DPCH, can determine the frame shifting amount of F-PCICH.In both identical situations of namely aliging in time of frame shifting amount, carry out the channel of PCI information regularly, because the obtain manner of frame shifting amount is simple, therefore realize conveniently.

In S220, according to update cycle, time slot format and timeslot number, determine the time slot sequence number of first time slot of carrying PCI information.

The update cycle of supposing PCI information is 3 time slots, so the timeslot number that complete PCI information takies can be 1,2 or 3.The time slot format of supposing again the time slot format of F-PCICH and F-PDCH is similar, namely in a time slot format, comprise 20 bits, symbol of 2 bit stealings, before carrying the first sets of bits of PCI information, has the second sets of bits that is similar to the NOFF1 bit, after the first sets of bits, has the 3rd sets of bits that is similar to the NOFF2 bit, bit number in the second sets of bits and the 3rd sets of bits can be used for distinguishing different time slot formats, and can not have bit in the second sets of bits or the 3rd sets of bits.Owing to can originally represent PCI information by 2 bit code, although and a symbol can carry 2 bits, 2 bits are identical dibits, so carry 2 symbols of a complete PCI informational needs.

Represent the timeslot number that the PCI information corresponding with pre-coding matrix takies with n, use N _Off1Represent the bit number in the second sets of bits, can indicate the side-play amount of the first sets of bits in a time slot of carrying PCI information, represent the time slot sequence number with i, the time slot sequence number increases progressively numbering since 0 in a F-PCICH frame, differs 1 between the adjacent time-slots sequence number.If 15 time slots are arranged in the F-PCICH frame, then the value of i is from 0 to 14 continuous integral number.In addition, as mentioned above, the update cycle of PCI information is 3 time slots.Next, the time slot sequence number of first time slot of how to confirm carrying PCI information under the different situations is described.

(1) when n is 1, if N _Off1Be 0, then the time slot sequence number of definite first time slot is satisfied divides exactly 3, if the bit number in the second sets of bits is to be not equal to 0 value, determines that then the satisfied remainder divided by 3 of time slot sequence number of first time slot is 2.

If be formulated, then can calculate in the following way the time slot sequence number of first time slot:

When n is 1, if N _Off1=0, then when time slot sequence number i satisfied i mod 3=0, this time slot sequence number was the time slot sequence number of carrying first time slot of PCI information.Therefore, when a F-PCICH frame comprised 15 time slots of time slot sequence number from 0 to 14, the time slot sequence number that can carry first time slot of PCI information was 0,3,6,9 or 12;

When n is 1, if N _Off1Greater than 0, then when time slot sequence number i satisfied (i+1) mod 3=0, this time slot sequence number was the time slot sequence number of carrying first time slot of PCI information.Therefore, when a F-PCICH frame comprised 15 time slots of time slot sequence number from 0 to 14, the time slot sequence number that can carry first time slot of PCI information was 2,5,8,11 or 14.

(2) when n is 2, if N _Of1Be 0 or 2, determine that then the satisfied remainder divided by 3 of time slot sequence number of first time slot is 2, if N _Off1Greater than 2, determine that then the satisfied remainder divided by 3 of time slot sequence number of first time slot is 1.

If be formulated, then can calculate in the following way the time slot sequence number of first time slot:

When n is 2, if N _Off1=0 or 2, then when time slot sequence number i satisfied (i+1) mod 3=0, this time slot sequence number was the time slot sequence number of carrying first time slot of PCI information.Therefore, when a F-PCICH frame comprised 15 time slots of time slot sequence number from 0 to 14, the time slot sequence number that can carry first time slot of PCI information was 2,5,8,11 or 14;

When n is 2, if N _Of1Greater than 2, then when time slot sequence number i satisfied (i+2) mod 3=0, this time slot sequence number was the time slot sequence number of carrying first time slot of PCI information.Therefore, when a F-PCICH frame comprised 15 time slots of time slot sequence number from 0 to 14, the time slot sequence number that can carry first time slot of PCI information was 1,4,7,10 or 13.

(3) when n is 3, if N _Off1Be 0 or 2, determine that then the satisfied remainder divided by 3 of time slot sequence number of first time slot is 1, if N _Off1Greater than 2, then the time slot sequence number of definite first time slot is satisfied divides exactly 3.

If be formulated, then can calculate in the following way the time slot sequence number of first time slot:

When n is 3, if N _Off1=0 or 2, then when time slot sequence number i satisfied (i+2) mod 3=0, this time slot sequence number was the time slot sequence number of carrying first time slot of PCI information.Therefore, when a F-PCICH frame comprised 15 time slots of time slot sequence number from 0 to 14, the time slot sequence number that can carry first time slot of PCI information was 1,4,7,10 or 13;

When n is 3, if N _Of1Greater than 2, then when time slot sequence number i satisfied (i+3) mod 3=0, this time slot sequence number was the time slot sequence number of carrying first time slot of PCI information.Therefore, when a F-PCICH frame comprised 15 time slots of time slot sequence number from 0 to 14, the time slot sequence number that can carry first time slot of PCI information was 0,3,6,9 or 12.

In S230, according to time slot sequence number and the timeslot number of first time slot, determine several time slot sequence numbers of time slot that the first time slot sequence number collection begins for the time slot sequence number from first time slot.

Owing in S220, having determined the time slot sequence number of first time slot of carrying PCI information, in conjunction with the timeslot number that PCI information takies, can determine time slot sequence number that complete PCI information is required of carrying.Several time slot sequence numbers of time slot can be continuous time slot sequence numbers, and time slot corresponding to continuous time slot sequence number is adjacent.For example, in the situation that n=2, if determine that in S220 the time slot sequence number of first time slot is 7, the time slot sequence number of then carrying PCI information is 7 and 8; If determine that in S220 the time slot of first time slot is 14, the time slot sequence number of then carrying PCI information is the time slot sequence number 14 of a F-PCICH frame and the time slot sequence number 0 of next F-PCICH frame; Etc..

Several time slot sequence numbers of time slot can be several time slot sequence numbers of continuous slot in the same F-PCICH frame.Several time slot sequence numbers of time slot also can be several time slot sequence numbers of continuous slot in adjacent two F-PCICH frames, wherein, at least one time slot sequence number is arranged in the end of the previous F-PCICH frame of these adjacent two F-PCICH frames, and at least one time slot sequence number is arranged in the head of a rear F-PCICH frame of these adjacent two F-PCICH frames.

In S240, according to time slot format, determine the character position that PCI information takies in a time slot.

When n was 1, the first sets of bits took adjacent and continuous two symbols behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits.Thereby, can determine that PCI information takies adjacent and continuous two symbols behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits in a time slot.

Because n is 1, so a complete PCI information only can be carried in the time slot.Because a complete PCI informational needs takies 2 symbols, so PCI information takies immediately following continuous two symbols behind the symbol that the second sets of bits takies.

When n was 2, the first sets of bits took the adjacent and symbol behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits.Thereby, can determine that PCI information takies the adjacent and symbol behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits in a time slot.

Because n is 2, so a complete PCI information can be carried in continuous two time slots, and because a complete PCI informational needs takies 2 symbols, so can in each time slot in continuous two time slots PCI information be taken immediately following a symbol behind the symbol that the second sets of bits takies, like this in each time slot with a symbols carry part PCI information, in two time slots with two PCI information that symbols carry is complete.

When n was 3, the first sets of bits took the adjacent and symbol behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits.Thereby, can determine that PCI information takies the adjacent and symbol behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits in a time slot.

Because n is 3, so a complete PCI information can be carried in continuous three time slots.Because a complete PCI informational needs takies 2 symbols, by redundancy encoding or other coding forms, can make a complete PCI information take 3 symbols, can make like this each the time slot bearing part PCI information in continuous three time slots, PCI information takies immediately following a symbol behind the symbol that the second sets of bits takies, thereby can carry PCI information in three time slots.

Although S240 carries out after S210, S220 and S230, it doesn't matter for the execution sequence of S240 and S210, S220 and S230, only needs to carry out before S250 to get final product.

In S250, send the F-PCICH frame according to frame shifting amount and time slot format to subscriber equipment, in time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number in character position carrying PCI information.

Below, describe according to the channel of the PCI information of method 200 regularly in conjunction with the object lesson of Fig. 3 and Fig. 4.Can see from Fig. 3 and example shown in Figure 4, subscriber equipment can be in time uses the pre-coding matrix corresponding with PCI information at the initial boundary of uplink physical channel subframe.

Fig. 3 is at N _Off1Be 0, n is the schematic diagram of the example of transmission PCI information in 1 the situation.

Descending (DL) P-CCPCH is synchronizing channel, determines fiducial time by this channel, thereby determines the frame shifting amount of other channels.The descending P-CCPCH of UTRAN (UMTS Terrestrial Radio Access Network, UMTS Terrestrial radio access network) side is used for the P-CCPCH frame that the expression base station sends to subscriber equipment.

Descending F-PCICH is the base station to the channel of the subscriber equipment feedback PCI information of supporting CLTD, uses the method for the transmission PCI information that embodiment of the invention provides at this channel.The descending F-PCICH of UTRAN side is used for the F-PCICH frame that the expression base station sends to subscriber equipment.The descending F-PCICH of UE side is used for the F-PCICH frame that the expression subscriber equipment is received from the base station.The base station sends the F-PCICH frame and the user receives that transmission delay T0 is arranged between the F-PCICH frame.

Up (UL) DPCCH is subscriber equipment sends channel from upstream data to the base station, need to use therein pre-coding matrix, and pre-coding matrix can be adjusted by the PCI information of base station feedback.The up DPCCH of UE side is used for the DPCCH frame that the expression subscriber equipment sends to the base station, and the up DPCCH of UTRAN side is used for the DPCCH frame that receive from subscriber equipment the expression base station.In the DPCCH frame, transmit such as PILOT (Pilot, pilot tone), TFCI (Transport Format Combination Indicator, transformat combination is indicated) and TPC (Transmit Power Control, transmitting power control) and so on data need to be used in the pre-coding matrix corresponding to PCI in the corresponding moment and be weighted, process is same as the prior art, does not repeat them here.

Although up channel shown in Figure 3 is DPCCH, up channel also can be the E-DPCCH, the E-DPDCH that align in time with up DPCCH, S-DPCCH etc.

The frame shifting amount τ of F-PCICH _F-PCICHWith the frame shifting amount of F-DPCH or the frame shifting amount τ of descending DPCH _F-DPCH/DPCHIdentical, so that subscriber equipment receives after the F-PCICH frame, be 1024 chips of standard code through descending and up timing slip (DL-UL timing offset, DL-UL timing slip), begin to send the upstream data of corresponding time slot sequence number.Frame shifting amount τ _F-PCICHBe the F-PCICH frame with respect to the time migration of P-CCPCH frame, frame shifting amount τ _F-DPCH/DPCHThat F-DPCH frame or descending DPCH frame are with respect to the time migration of P-CCPCH frame.

For example, in the radio frames on P-CCPCH shown in Figure 3, having SFN mould 2 and be 0 radio frames (Radio Frame) and having SFN mould 2 is that 1 radio frames is adjacent radio frames, can be by having the initial boundary definition frame shifting amount that SFN mould 2 is 1 radio frames.The F-PCICH frame is defined as τ with respect to the time migration on this initial border _F-PCICH, F-DPCH frame or descending DPCH frame are defined as τ with respect to the time migration on this initial border _F-DPCH/DPCHCertainly, on P-CCPCH, when the previous radio frames in adjacent two radio frames has SFN mould 2 when being 1, it is 0 that the rear radio frames in adjacent two radio frames has SFN mould 2.

Although the time slot #0 that has only specifically illustrated the F-PCICH frame in Fig. 3 carries the situation of PCI information to time slot #2, but because per 3 time slots of PCI information upgrade once, time slot #0 can carry PCI information to the situation that time slot #2 has represented to carry in the update cycle PCI information at subsequent timeslot as time slot #0 carries PCI information to time slot #2 mode.In addition, a subframe lengths is 2ms.In addition, in Fig. 3 and follow-up Fig. 4, Fig. 6 and Fig. 7, represent time slot corresponding to time slot sequence number i with time slot #i.For example, time slot #0 represents the time slot of time slot sequence number 0 correspondence.

Because N _Off1Be 0, n is 1, so time slot #0 can be first time slot that carries PCI information.Because n is 1, so carry complete PCI information in time slot #0, takies 2 symbols.Because N _Off1Be 0, thus the bit number in the second sets of bits be in 0, the second sets of bits without any bit, PCI information takies first symbol and second symbol of time slot #0.

Because F-PCICH and F-DPCH are similar, so 1 symbol is 256 chips (chip), two symbols of carrying PCI information take 512 chips.After subscriber equipment is received PCI information, regulation according to standard, need to could use pre-coding matrix corresponding to PCI information through the time of at least 512 chips, therefore last symbol of the complete PCI information of carrying received of subscriber equipment needs at least 512 chips in initial border of distance D PCCH uplink physical channel subframe, the PCI information that subscriber equipment just can use the time slot #0 of F-PCICH frame to carry at the initial boundary of uplink physical channel subframe.In Fig. 3, by utilizing the timing mode of the embodiment of the invention, the distance that time slot #0 carries between the initial border of the symbol of PCI and DPCCH uplink physical channel subframe is 1024-512=512 chip, satisfy the subscriber equipment needs and wait for that at least the time of 512 chips could use the requirement of pre-coding matrix corresponding to PCI information, therefore subscriber equipment has pre-coding matrix corresponding to sufficient time application PCI information to be weighted, and can in time use pre-coding matrix corresponding to PCI information.

Fig. 4 is at N _Off1Be 0, n is the schematic diagram of the example of transmission PCI information in 2 the situation.The related channel of the related channel of Fig. 4 and Fig. 3 is identical, and difference is, because the timeslot number that PCI information takies changes, so that the channel of PCI information is regularly different.

Because N _Off1Be 0, n is 2, so time slot #14 can be first time slot that carries PCI information.Because n is 2, so in time slot #14 and follow-up time slot #0, carry complete PCI information, in time slot #14, take a symbol, in time slot #0, take a symbol, the symbol of time slot #14 and time slot #0 is combined the complete PCI information that obtains.Because N _Off1Be 0, take first symbol of time slot #14 and first symbol of time slot #0 so the bit number in the second sets of bits is 0, PCI information.

Because the frame shifting amount of F-PCICH equates with the frame shifting amount of F-DPCH or the frame shifting amount of descending DPCH, the DL-UL timing slip has the timing offset of 1024 chips, 1 symbol is 256 chips, so that the spacing between the initial border of first symbol of time slot #0 and DPCCH uplink physical channel subframe is 1024-256=768 chip, receive that greater than subscriber equipment PCI information is to using 512 required chips of PCI information, so that subscriber equipment is after receiving PCI information, can in time use pre-coding matrix corresponding to this PCI information, thereby can improve upstream data to the speed-adaptive of channel condition, improve systematic function.

In addition, at N _Off1Be 2, n is that the channel of PCI information is regularly similar to Fig. 4 in 2 the situation, difference is to also have a symbol before the symbol that carries PCI information, and this symbol may carry concrete bit, also can not carry any bit, just occupy the position of a symbol.

Although Fig. 3 and Fig. 4 only show channel two examples regularly of PCI information, under the inspiration and instruction of Fig. 3 and Fig. 4, those skilled in the art also can easily derive the channel timing of PCI information in other situations, do not repeat them here.

Next, the method 500 of describing according to the transmission PCI information of the embodiment of the invention with reference to figure 5.

In S510, according to the frame shifting amount of F-DPCH or frame shifting amount, time slot format and the timeslot number of descending DPCH, obtain the frame shifting amount of F-PCICH.

Because equipment of the core network can be to the frame shifting amount of base station and notification of user equipment F-DPCH or the frame shifting amount of descending DPCH, so the base station can calculate the frame shifting amount of F-PCICH again in conjunction with time slot format and timeslot number.Send the F-PCICH frame by the frame shifting amount according to F-PCICH, can make subscriber equipment in time use pre-coding matrix corresponding to PCI information.

The update cycle of still supposing PCI information is 3 time slots, and the time slot format of F-PCICH and the time slot format of F-PDCH are similar, describes the frame shifting amount that how specifically to obtain F-PCICH under the different situations.Hereinafter, represent the timeslot number that PCI information takies with Tq, use N _Off1Represent the bit number in the second sets of bits, use τ _F-PCICHThe frame shifting amount of expression F-PCICH is used τ _F-DPCH/DPCHThe expression frame shifting amount of F-DPCH or the frame shifting amount of descending DPCH, wherein frame shifting amount is same index that same subscriber equipment or network side are distributed.

(1) when Tq is 1, if N _Off1Be 0, then determine τ _F-PCICHEqual τ _F-DPCH/DPCHIf, N _Off1Greater than 0, then determine τ _F-PCICHWith τ _F-DPCH/DPCHDifference be 1 side-play amount that time slot is corresponding.Wherein, 1 time slot can comprise 10 symbols, and 1 symbol has 256 chips, so 1 side-play amount corresponding to time slot can be 2560 chips.

If be formulated, then can obtain in the following way the frame shifting amount of F-PCICH:

When Tq=1, if N _Off1=0, then

τ _F-FPCICH＝τ _F-DPCH/DPCH；

When Tq=1, if N _Off1Greater than 0, then

τ _F-FPCICH＝τ _F-DPCH/DPCH-2560。

(2) when Tq is 2, if N _Off1Be 0 or 2, then determine τ _F-PCICHWith τ _F-DPCH/DPCHDifference be 1 side-play amount that time slot is corresponding, if N _Off1Greater than 2, then determine τ _F-PCICHWith τ _F-DPCH/DPCHDifference be 2 side-play amounts that time slot is corresponding.Wherein, 1 side-play amount corresponding to time slot can be 2560 chips.

If be formulated, then can obtain in the following way the frame shifting amount of F-PCICH:

When Tq=2, if N _Off1=0 or 2, then

τ _F-FPCICH＝τ _F-DPCH/DPCH-2560；

When Tq=2, if N _Off1Greater than 2, then

τ _F-FPCICH＝τ _F-DPCH/DPCH-5120。

(3) when Tq is 3, if N _Off1Be 0 or 2, then determine τ _F-PCICHWith τ _F-DPCH/DPCHDifference be 2 side-play amounts that time slot is corresponding, if N _Off1Greater than 2, then determine τ _F-PCICHWith τ _F-DPCH/DPCHDifference be 3 side-play amounts that time slot is corresponding.Wherein, 1 side-play amount corresponding to time slot can be 2560 chips.

If be formulated, then can obtain in the following way the frame shifting amount of F-PCICH:

When Tq=3, if N _Off1=0 or 2, then

τ _F-FPCICH＝τ _F-DPCH/DPCH-5120；

When Tq=3, if N _Off1Greater than 2, then

τ _F-FPCICH＝τ _F-DPCH/DPCH-7680。

In S520, according to the update cycle, determine the time slot sequence number of first time slot of carrying PCI information.

For the F-PCICH frame of a certain CFN, the time slot sequence number i of first time slot satisfies:

(15*CFN+i)modPCI_Update_cycle＝0

Wherein, a F-PCICH frame has 15 time slots, and PCI_Update_cycle is the update cycle of PCI information.

When PCI_Update_cycle was 3, the time slot sequence number i of first time slot satisfied i mod 3=0.Therefore, when the F-PCICH frame comprised 15 time slots of time slot sequence number from 0 to 14, the time slot sequence number that can carry first time slot of PCI information was 0,3,6,9 or 12.

In S530, according to time slot sequence number and the timeslot number of first time slot, determine several time slot sequence numbers of time slot that the first time slot sequence number collection begins for the time slot sequence number from first time slot.

Owing in S520, having determined the time slot sequence number of first time slot of carrying PCI information, in conjunction with the timeslot number that PCI information takies, can determine time slot sequence number that complete PCI information is required of carrying.Carrying a required time slot sequence number of complete PCI information can be continuous time slot sequence number, thereby can carry by continuous time slot a complete PCI information.According to embodiments of the invention, because first time slot of the F-PCICH subframe that the time slot sequence number of first time slot of determining among the S520 is the F-PCICH frame to be comprised, and the update cycle is 3 time slots, so the time slot sequence number that the first time slot sequence number is concentrated is the time slot sequence number of same F-PCICH frame.

In S540, according to time slot format, determine the character position that PCI information takies in a time slot.

When Tq is 1, according to time slot format, determine that PCI information takies adjacent and continuous two symbols behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits.Wherein, in time slot format, the first sets of bits takies immediately following continuous two symbols behind the symbol that the second sets of bits takies.

When Tq=2 or 3, according to time slot format, determine that PCI information takies the adjacent and symbol behind the symbol that the second sets of bits takies of the symbol that takies with the second sets of bits.Wherein, in time slot format, the first sets of bits takies immediately following a symbol behind the symbol that the second sets of bits takies.

In S550, send the F-PCICH frame according to frame shifting amount and time slot format to subscriber equipment, in time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number in character position carrying PCI information.

Wherein, the F-PCICH frame can be the F-PCICH frame corresponding with a certain CFN.

Below, describe according to the channel of the PCI information of method 500 regularly in conjunction with the object lesson of Fig. 6 and Fig. 7.Can see from Fig. 6 and example shown in Figure 7, subscriber equipment can be in time uses the pre-coding matrix corresponding with PCI information at the initial boundary of uplink physical channel subframe.

Fig. 6 is at N _Off1Be 0, Tq is the schematic diagram of the example of transmission PCI information in 1 the situation.

The description of descending P-CCPCH, descending F-PCICH and up DPCCH is identical with Fig. 3.But in Fig. 6, the frame shifting amount of F-PCICH is not necessarily identical with the frame shifting amount of the frame shifting amount of F-DPCH or descending DPCH.

Although the time slot #0 that has only specifically illustrated the F-PCICH frame in Fig. 6 carries the situation of PCI information to time slot #2, but because per 3 time slots of PCI information upgrade once, can as time slot #0 carries PCI information to time slot #2 mode, carry PCI information at subsequent timeslot.

Because Tq is 1, so carry complete PCI information at time slot #0, takies 2 symbols, and τ _F-PCICHWith τ _F-DPCH/DPCHEquate.Because N _Off1Be 0, take first symbol and second symbol of time slot #0 so the bit number in the second sets of bits is 0, PCI information.

Because F-PCICH and F-DPCH are similar, so 1 symbol is 256 chips, two symbols of carrying PCI information take 512 chips.Subscriber equipment is received the downlink frame of F-PCICH frame and DPCCH through transmission delay T0, and process DL-UL timing slip is the uplink frame that 1024 chips can send DPCCH.Therefore as can see from Figure 6, last symbol and the distance between the DPCCH uplink physical channel subframe of carrying PCI information are 1024-512=512 chip, satisfy the subscriber equipment needs and wait for that at least the time of 512 chips could use the requirement of pre-coding matrix corresponding to PCI information, so subscriber equipment can in time use pre-coding matrix corresponding to PCI information.

Fig. 7 is at N _Off1Be 0, Tq is the schematic diagram of the example of transmission PCI information in 2 the situation.The related channel of the related channel of Fig. 7 and Fig. 6 is identical, and difference is, because the timeslot number that PCI information takies changes, so that the channel of the frame shifting amount of F-PCICH and PCI information is regularly different.

Because Tq is 2, so time slot #0 and time slot #1 carry a complete PCI information, and τ _F-PCICHCompare τ _F-DPCH/DPCHThe side-play amount of little 2560 chips namely sends the time of F-PCICH frame than 1 time slot of time advance of the downlink frame that sends DPCCH.Because N _Off1Be 0, take first symbol of time slot #0 and first symbol of time slot #1 so the bit number in the second sets of bits is 0, PCI information, the symbol of time slot #0 and time slot #1 is combined the PCI information that obtains.

When the base station according to τ _F-PCICHSend after the F-PCICH frame, subscriber equipment receives the F-PCICH frame through T0, and therefrom obtains PCI information.The base station is according to τ _F-DPCH/DPCHSend the downlink frame of DPCCH, subscriber equipment is received the downlink frame of DPCCH through T0, wait for the descending time that turns 1024 chips of uplink timing error, begins to send DPCCH uplink physical channel subframe.Distance between the initial border of last symbol of the PCI information that subscriber equipment is received and DPCCH uplink physical channel subframe is 1024-256=768 chip, receive that greater than subscriber equipment PCI information is to using 512 chips corresponding to pre-coding matrix required time corresponding to PCI information, so that subscriber equipment after receiving PCI information, has pre-coding matrix corresponding to this PCI information of sufficient time application to be weighted.

In addition, at N _Off1Be 2, Tq is that the channel of PCI information is regularly similar to Fig. 7 in 2 the situation, difference is to also have a symbol before the symbol that carries PCI information, and this symbol may carry concrete bit, also can not carry any bit, just occupy the position of a symbol.

Although Fig. 6 and Fig. 7 only show channel two examples regularly of PCI information, under the inspiration and instruction of Fig. 6 and Fig. 7, those skilled in the art also can easily derive the channel timing of the PCI information in other situations, do not repeat them here.

The above has described the channel timing of PCI information when the base station sends PCI information, and the channel of PCI information regularly when describing subscriber equipment reception PCI information below in conjunction with Fig. 8 to Figure 11.Because subscriber equipment need to adopt the channel timing mode identical with the base station to obtain PCI information, therefore subscriber equipment determines that the channel of PCI information regularly determines that with the base station channel of PCI information is regularly identical, can be by help understand the channel mode regularly that subscriber equipment is determined PCI information referring to figs. 1 to the description of Fig. 7, for fear of repetition, the below simply describes.

Fig. 8 is the flow chart according to the method 800 of the transmission PCI information of the embodiment of the invention.

As shown in Figure 8, method 800 comprises: in S810, obtain the frame shifting amount of F-PCICH; In S820, take timeslot number on the F-PCICH according to the time slot format of the F-PCICH of update cycle of PCI information, subscriber equipment and PCI information, determine the first time slot sequence number collection of carrying PCI information, and the character position that in a time slot, takies of definite PCI information, wherein, PCI information is corresponding with a pre-coding matrix; In S830, receive the F-PCICH frame that the base station sends according to frame shifting amount and time slot format, in time slot corresponding to the time slot sequence number of concentrating with the first time slot sequence number, extract PCI information from character position.

For example, method 800 can be carried out by subscriber equipment.When subscriber equipment was supported CLTD, the base station need to be by F-PCICH to subscriber equipment feedback PCI information.By said method, can realize the timing of PCI information in the F-PCICH frame.By according to time slot format, take the time slot sequence number that timeslot number, update cycle are determined carrying PCI information, subscriber equipment can extract PCI information from the F-PCICH frame, is conducive to use corresponding pre-coding matrix according to the PCI information that extracts at the initial boundary of uplink physical channel subframe.

The related content of S810 and S820 can be with reference to the description of S110 and S120.Although S820 carries out after S810, when S820 determined that the first time slot sequence number collection and frame shifting amount are irrelevant, S820 also can carry out before S810, can also with the concurrent execution of S810.

In S830, the frame shifting amount of the F-PCICH that obtains according to S810, subscriber equipment can know when the base station begins to send the F-PCICH frame, thus subscriber equipment wait for according to the confirmable transmission delay T0 of prior art, receive the F-PCICH frame.

The character position that the first time slot sequence number collection that subscriber equipment is determined according to time slot format with in S820 and PCI information take can extract PCI information from the F-PCICH frame that receives.

According to embodiments of the invention, can according to the time slot format of the F-PCICH of update cycle of PCI information, subscriber equipment, PCI information take on the F-PCICH timeslot number and based on the Connection Frame Number of frame shifting amount, determine the second time slot sequence number collection of carrying PCI information in F-PCICH frame corresponding to Connection Frame Number, and the character position that in a time slot, takies of definite PCI information, the second time slot sequence number collection is the subset of the first time slot sequence number collection.

In this case, when the element number of the second time slot sequence number collection equals timeslot number, receive F-PCICH frame corresponding to Connection Frame Number that the base station sends according to frame shifting amount and time slot format, in time slot corresponding to the time slot sequence number of concentrating with the second time slot sequence number, extract PCI information from character position.Perhaps, when the element number of the second time slot sequence number collection during than the little N of timeslot number, receive F-PCICH frame corresponding to Connection Frame Number that the base station sends and the next F-PCICH frame of this F-PCICH frame according to frame shifting amount and time slot format, in a beginning N time slot of time slot corresponding to the time slot sequence number of concentrating with the second time slot sequence number and next F-PCICH frame from character position extraction PCI information.
