After high-level business packet reaches and sends and cache and obtain and can be used for sending the running time-frequency resource of SR, LTE-V user exists SR request is sent to eNodeB on Physical Uplink Control Channel (Physical Uplink Control Channel, PUCCH). The SR of each user occupies a PRB, and using the structure of frequency hopping between time slot, as shown in figure 3, one sharing 4 in each time slot Data (Data, DA) symbol, 3 reference signal (Reference Signal, RS) symbols.Using cyclic shift, orthogonal code with Scrambling code, a PRB can accommodate 36 users simultaneously and send SR.This 36 users are classified as one group, are indicated with UEG1.

As it can be seen from table 1 total average scheduling delay is T/2+17TTI (ms).This means that SR cycle T is longer, The scheduling of resource time delay that LTE-V user expends on Uu mouth is bigger.The running time-frequency resource between certain and user in available running time-frequency resource In the case where not conflicting, system user number is more, and the dispatching cycle of user is longer.By taking TDD proportion 2 as an example, it is assumed that system only has One PRB can be used for scheduling of resource.Since a PRB can accommodate 36 users, as shown in Fig. 2, UEG1 indicates one group 36 User, UEG2 indicate 36 users of another set.When system user quantity is not more than 36, the dispatching cycle of each user is 5TTI, when system user quantity is greater than 36 and is not more than 72, the dispatching cycle of each user becomes 10TTI.

Using the SR resource impact scheme of the prior art, 36 users can only be at most accommodated simultaneously in a PRB.This is main It is 3 because a PRB for being used for transmission SR uses the scheme of frequency hopping between time slot, and has 4 DA symbols in each time slot R/S symbol.The corresponding 4 groups of different orthogonal codes of 4 DA symbols, the corresponding three groups of different orthogonal codes of 3 R/S symbols.But due to one Only 3 R/S symbols in a time slot, to support multiple one PRB of user's concurrent multiplexing, system can only at most use 3 groups it is different Orthogonal code, as shown in table 2, each group of orthogonal code include 14 orthogonal codes, this 14 code words are distributed on one that sends SR 14 symbols of row subframe.In addition, a PRB mono- shares 12 subcarriers, 12 kinds of different cyclic shifts are supported altogether.3 groups Together with the different orthogonal codes cyclic shift different with 12 kinds, 36 groups of mutually orthogonal time frequency signals are generated, it is different for 36 User uses simultaneously.

Table 2

If only one PRB and LTE-V number of users of system is more than 36, between users the case where No Assets conflict Under, the average scheduling delay of each user increases.TS 22.185 requires LTE-V business data packet to be cached to hair from transmission is reached The time delay seen off is not more than 20ms.

In order to solve increasing with user capacity existing in the prior art, the scheduling of resource time delay on Uu mouth is expended Increase, causes the scheduling of resource time delay on Uu mouth to be unsatisfactory for business demand, the application provides a kind of ascending control information dispatching party Method, realization accommodate more users in a PRB, reduce each user's in the case where resource contention between not increasing user Average scheduling delay, to meet the delay requirement of LTE-V.Further, the core of the application is ensuring different user DA symbol between and R/S symbol between it is orthogonal in the case where, reduce LTE- by promoting the capacity of SR in a PRB Average resource scheduling delay of the V user in Mode3.

The application provides a kind of uplink control information transmission method, as shown in figure 4, mainly comprising the steps that

Step 101, terminal reports the short SR ability to base station report oneself to base station；

The terminal can be arranged to the terminal with short SR signal transmitting capacity, be also possible to be configured to send short SR signal can also send the terminal of traditional SR signal.After terminal reports the short SR ability of oneself to base station, base station is according to being Overall performance unite to determine whether terminal sends short SR signal.The terminal is LTE vehicle-mounted end in system architecture shown in Fig. 1 End, i.e. LTE-V user.

Step 102, short SR ability of the base station according to terminal, the instruction information sent to terminal, instruction terminal send short SR Resource information needed for signal；

Step 103, terminal configures short SR signal according to the instruction information of base station on sub-frame of uplink, and determines short SR letter Number occupy 7 symbols resource location；

Wherein, the short SR signal of configuration occupies 7 symbols of sub-frame of uplink, and short SR signal is used to indicate base station and carries out uplink Scheduling of resource, the resource location of 7 symbols that the mode and short SR signal for configuring short SR signal occupy indicate by base station, Huo Zhe It is pre-configured in terminal.

For example, base station in such a way that Downlink Control Information configures short SR signal to terminal instruction and can send short SR The resource location of signal.For example, base station sends instruction information to terminal, instruction information instruction terminal sends short scheduling request SR letter Number sub-frame of uplink, the symbolic number that is occupied on sub-frame of uplink of short SR signal be 7 symbols that 7 symbols, short SR signal occupy Corresponding orthogonal code and the corresponding resource location of 7 symbols, 7 symbols include 4 data symbols and 3 reference signal symbols Number, so that terminal configures short SR signal, and send short SR signal on resource location according to instruction information on sub-frame of uplink.

It mainly includes that symbol is cut and code word two processes of distribution that terminal instruction, which configures short SR signal,.Symbol is cut mainly 7 symbols are cut from 14 original symbols of the sub-frame of uplink, obtain 7 symbols for needing to retain；Code word distribution Mainly according to the instruction information, the corresponding orthogonal code of 7 symbols is determined.Then corresponding according to 7 symbols Orthogonal code, 7 symbols are modulated to form the short SR signal.

Terminal generates 14 original symbols from collocating uplink subframe position, includes 8 data symbols in 14 original symbols With 6 reference signal symbols, terminal cuts 7 symbols from 14 original symbols of sub-frame of uplink for sending short SR signal and retains 7 symbols, 7 symbols of reservation include 4 data symbols and 3 reference signal symbols, and 7 symbols of reservation are short for sending SR signal.After cutting symbol, terminal is that 7 symbols retained configure one group of orthogonal code, this group of orthogonal code includes 7 Orthogonal code, this 7 orthogonal codes are sequentially allocated to 7 symbols of reservation.Wherein, the orthogonal code for the distribution of short SR signal is The orthogonal code that length is 7.Needing to cut which symbol can be configured by base station or be pre-configured in the terminal.

The process that terminal carries out code word distribution is configured by base station, specifically, the terminal is determined according to the instruction information The corresponding orthogonal code of 7 symbols, comprising: the terminal according to the instruction information, by one group of length be 14 it is orthogonal Code word splits to form the first subgroup orthogonal code and the second subgroup orthogonal code, the first subgroup orthogonal code and described second Subgroup orthogonal code all includes 7 orthogonal codes, and the orthogonal code that one group of length is 14 is that three groups of length being pre-configured are Any one group in 14 orthogonal code；When determining that the terminal is the first class of subscriber, by the first subgroup orthogonal code In 7 orthogonal codes distribute to 7 symbols；When determining that the terminal is second user classification, by second subgroup 7 orthogonal codes in orthogonal code distribute to 7 symbols.

Wherein it is determined that the resource location for 7 symbols that short SR signal occupies is indicated that 7 symbols are corresponding by base station Resource location includes 4 data symbols and data symbol and its son load on a Physical Resource Block under different frequency-hopping modes The mapping relations of wave position further include under different frequency-hopping modes on 3 reference signal symbols and the Physical Resource Block The mapping relations of reference signal symbol and its sub-carrier positions, specific example is in paragraphs detail below.

Step 104, terminal sends short SR signal on determining resource location.

Step 105, base station receives short SR signal, and carries out ascending resource scheduling for received short SR signal.

The specific implementation that terminal configures short SR signal is as follows:

(1) 14 original symbols in sub-frame of uplink, including 8 DA symbols and 6 R/S symbols are generated；

The sub-frame of uplink is the subframe for being allocated to terminal and sending SR, which occupies 2 time slots, and each time slot includes 7 Symbol, the resource location of each symbol are pre-configured.Such as Fig. 3, wherein the 3rd symbol, the 4th symbol and the 5th symbol It number is the R/S symbol of first time slot, the 10th symbol, the 11st symbol and the 12nd symbol are the R/S symbol of second time slot, 1st symbol, the 2nd symbol, the 6th symbol and the 7th symbol are the DA symbol of first time slot, the 8th symbol, the 9th A symbol, the 13rd symbol and the 14th symbol are the DA symbol of second time slot.

The corresponding resource location of DA symbol is the 1st symbol, the 2nd symbol, the 6th symbol, the 7th symbol of sub-frame of uplink Number, the 8th symbol, the 9th symbol, the 13rd symbol and the 14th corresponding resource location of symbol, R/S symbol it is corresponding Resource location is the 3rd symbol, the 4th symbol, the 5th symbol, the 10th symbol, the 11st symbol and the 12nd of sub-frame of uplink The corresponding resource location of a symbol.Each DA symbol and R/S symbol corresponding 12 subcarriers on a frequency band.

Wherein, LTE-V user is by carrying out cyclic shift to root sequence in the DA symbol and R/S symbol of each time slot It obtains.According to TS 36.211, root sequence is generated according to u, v value, and wherein u value and v value are by RB number, cell ID (Cell ID), sequence jumps mark (Seq Hopping), group jumps and indicates (Group Hopping) and timeslot number (Slot Idx) jointly certainly It is fixed.If jumped using group, first time slot is different from u, v value of second time slot, in other words first time slot and at second The root sequence of gap is different；Otherwise, u, v value of first time slot and second time slot are identical, in other words a time slot and The root sequence of two time slots is identical.The root sequence of DA symbol and the root sequence of R/S symbol are identical in each time slot.It is obtaining Carry out cyclic shifts according to 36.211 pairs of root sequences of TS after root sequence, to obtain corresponding DA symbol and R/S symbol.This step Suddenly the content prior art being related to is identical, is not repeated herein.

(2) existing three groups of orthogonal codes are split

It is DA after obtaining DA symbol and R/S symbol to enable eNodeB to distinguish the signal of different LTE-V users Symbol and R/S symbol distribute orthogonal code.Any one group of orthogonal code division in three groups of orthogonal codes in table 2 is given 12 by the prior art A LTE-V user uses simultaneously.For example, first group of orthogonal code division is used simultaneously to 12 LTE-V users, but this 12 not With the cyclic shift of signal that uses of LTE-V user be different, i.e., maintained by 12 kinds of different cyclic shifts this 12 Orthogonality between a LTE-V subscriber signal.

In order to make a PRB accommodate more SR, i.e., 72 users are supported to send SR simultaneously, the application will be orthogonal by three groups Any one group of orthogonal code division in code is used to 24 LTE-V users.In order to enable eNodeB to distinguish this 24 LTE-V users Signal, need to make the signal phase enantiotropy of this 24 LTE-V users.This application provides a kind of feasible method for splitting, make It obtains any one group of orthogonal code and splits into 2 groups of orthogonal codes, and can guarantee the orthogonality of this two groups of orthogonal codes, the orthogonal code Fractionation indicated by base station.

Specific method for splitting are as follows: each group orthogonal code that length is 14 is split as two parts, the length of each part It is 7, the 1st group of orthogonal code that the length that the 1st group of orthogonal code that the length in table 2 is 14 is split into table 3 and table 4 is 7, will The 2nd group of orthogonal code that length in table 2 is 14 splits into the 2nd group of orthogonal code that length in table 3 and table 4 is 7, by the length in table 2 Degree splits into the 3rd group of orthogonal code that length in table 3 and table 4 is 7 for 14 the 3rd group of orthogonal code.Wherein table 3 is the first orthogonal code Concordance list, table 4 are the second orthogonal code concordance list.Any two groups of orthogonal codes in table 3 are mutually orthogonal, and any two groups in table 4 Orthogonal code is mutually orthogonal.

Such as table 3, the notation index for the orthogonal code that each group of length is 7 be the 4th symbol, the 5th symbol, the 6th symbol, 7th symbol, the 8th symbol, the 9th symbol and the 10th symbol.

Such as table 4, the notation index for the orthogonal code that each group of length is 7 be the 1st symbol, the 2nd symbol, the 3rd symbol, 11st symbol, the 12nd symbol, the 13rd symbol and the 14th symbol.

It should be noted that be only for example according to a kind of fractionation mode that table 3 and table 4 are illustrated, the application includes but unlimited In above-mentioned fractionation mode, the orthogonal code that any one group of length is 14 from table 2 is split as 2 subgroup orthogonal codes, every height Group orthogonal code include any fractionation mode of 7 orthogonal codes all within the scope of protection of this application.

Table 4

(3) according to class of subscriber, extra 4 DA symbols and 3 R/S symbols are cut from 14 original symbols.

User's classification is carried out first, user can be grouped using various ways, simplest a kind of point Group mode is exactly the user that ID is odd number to be divided into one group, and the user that ID is even number is divided into one group.If ID is odd number User is the first class of subscriber, and ID is that the user of even number is second user classification.

14 original symbols of each LTE-V user include 8 DA symbols and 6 R/S symbols, after being split to orthogonal code, The length of every group of orthogonal code only has 7, it is therefore desirable to which 14 original symbols of each LTE-V user are cut half.Each 14 original symbols of LTE-V user are left 7 symbols, including 4 DA symbols and 3 RS after symbol is cut Symbol.

Optionally, if the user of each group of the first class of subscriber of orthogonal code division dispensing in table 3, each group in table 4 The user of orthogonal code division dispensing second user classification.The user of first class of subscriber can accord with the 4th in 14 original symbols Number, the 5th symbol, the 6th symbol, the 7th symbol, the 8th symbol, the 9th symbol and the 10th symbol retain, by the 1st Symbol, the 2nd symbol, the 3rd symbol, the 11st symbol, the 12nd symbol, the 13rd symbol and the 14th symbol are cut.The The user of two class of subscribers can by 14 original symbols the 1st symbol, the 2nd symbol, the 3rd symbol, the 11st symbol, 12nd symbol, the 13rd symbol and the 14th symbol retain, by the 4th symbol, the 5th symbol, the 6th symbol, the 7th symbol Number, the 8th symbol, the 9th symbol and the 10th symbol cut.Or it in turn can also be with.

Optionally, method can also be cut using other, for example, the symbol of the 1st time slot of original symbol is retained, it will be former The symbol of the 2nd time slot of beginning symbol is cut, and any one group of orthogonal code in such table 3 or table 4 can also give the 1st of reservation 7 symbols of time slot.Or the symbol of the 1st time slot can also be cut, the symbol of the 2nd time slot of original symbol is retained.This The symbol of sample cuts resource impact scheme of the scheme suitable for frequency hopping in time slot.

Certain the application include but is not limited to it is above two cut mode, other cut the mode of 7 symbols in this Shen Within protection scope please.

(4) the 4 DA symbols and 3 R/S symbols to retain distribute orthogonal code

7 elements in code word that length is 7 after code word is split, successively give the LTE-V user after symbol is cut 7 symbols, i.e., each symbol get in order length be 7 code word in an element.

For example, if the user of any one group of the first class of subscriber of orthogonal code division dispensing in table 3, it is any in table 3 One group code index is the 4th symbol, the 5th symbol, the 6th symbol, the 7th symbol, the 8th symbol, the 9th symbol and the The orthogonal code of 10 symbols is sequentially allocated in 7 symbols retained to the user of the first class of subscriber, the use of the first class of subscriber 7 symbols that family retains just are the 4th symbol, the 5th symbol, the 6th symbol, the 7th symbol, the 8th symbol, the 9th Symbol and the 10th symbol.

Any one group of orthogonal code if the user of each group of the first class of subscriber of orthogonal code division dispensing in table 3, in table 3 The user that 12 the first class of subscribers can be distributed to uses, if each group of orthogonal code division dispensing second user class in table 4 Other user, the user that any one group of orthogonal code in table 4 can distribute to 12 second user classifications use.Using this code Word allocation plan, any one group of orthogonal code in table 1 can guarantee that the signal of 24 LTE-V users is mutually orthogonal, this master If because after 24 users are divided into two groups, 12 users of the first class of subscriber and 12 users of second user classification Between signal it is orthogonal by way of time-division/frequency division；And for any one group of 12 users, subscriber signal passes through root sequence Cyclic shift it is orthogonal.

(5) according to the corresponding orthogonal code of 7 symbols, 7 symbols are modulated to form the short SR letter Number.

After configuring good short SR signal, the resource location for sending short SR signal, i.e. 4 DA symbols and 3 RS symbols are determined Number corresponding resource location.

Wherein it is determined that the specific implementation for sending the resource location of short SR signal is as follows:
