Table 9 (20, A) Ma basic sequence

Below in conjunction with Figure of description the embodiment of the invention is described in further detail.

Shown in Fig. 2 A, embodiment of the invention network equipment comprises: subframe determination module 10, modular converter 20 and mapping block 30.

Subframe determination module 10 is used for determining the up backhaul subframe in edge that wherein the part SC-FDMA symbol in the up backhaul subframe in edge is GP.

Wherein, if up backhaul subframe adjacent with non-up back haul link subframe (being the up backhaul subframe in edge) then needs to take the part SC-FDMA symbol of up backhaul subframe as GP.

Suppose that the SC-FDMA symbol adopts conventional CP, promptly comprise 7 SC-FDMA symbols in each time slot of the up backhaul subframe in edge, then have two kinds of situations.

Situation one, shown in Fig. 2 B, the both sides of the up backhaul subframe in edge are the up backhaul subframe of right and wrong (being that two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot) all, first SC-FDMA symbol of first time slot that then takies the up backhaul subframe in edge is as GP, and last (promptly the 7th) the SC-FDMA symbol of second time slot that takies the up backhaul subframe in this edge is as GP.

Situation two, shown in Fig. 2 C, the up backhaul subframe of side right and wrong of the up backhaul subframe in edge, (being that two time slots that comprise in the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot).

If the GP position is arranged in first time slot of the up backhaul subframe in edge, first SC-FDMA symbol that then takies first time slot is as GP; If the GP position is arranged in second time slot of the up backhaul subframe in edge, last (promptly the 7th) the SC-FDMA symbol that then takies second time slot is as GP.

Need to prove that the embodiment of the invention is not limited to above-mentioned two kinds of GP positions and quantity, other positions of GP and quantity are suitable for the embodiment of the invention equally, take 1 half symbol as GP such as each.

Modular converter 20, be used for need be at the edge PUCCH data information transmitted and the demodulation pilot frequency information of up backhaul subframe be converted to data complex sequences and demodulation pilot frequency complex sequences respectively, wherein the SC-FDMA symbol quantity that takies of data complex sequences is not more than the quantity of the first available SC-FDMA symbol that is used to carry the data complex sequences among the PUCCH.

Mapping block 30 is used for the second available SC-FDMA symbol that is mapped to data complex sequences and demodulation pilot frequency complex sequences on the first available SC-FDMA symbol of PUCCH respectively and is used to carry the demodulation pilot frequency complex sequences among the PUCCH.

Comprise three kinds of SC-FDMA symbols in the up backhaul subframe in edge, be respectively the first available SC-FDMA symbol that is used to carry the data complex sequences, be used for carrying the second available SC-FDMA symbol (being the RS of Fig. 2 B and Fig. 2 C) of demodulation pilot frequency complex sequences and as the SC-FDMA symbol of GP.

The first available SC-FDMA symbol and the second available SC-FDMA symbol be at time domain orthogonal, and the first available SC-FDMA symbol in the up backhaul subframe in edge and the second available SC-FDMA quantative attribute sum equal the SC-FDMA symbol quantity except that GP among the PUCCH of the up backhaul subframe in edge.

Wherein, the PUCCH form of the up backhaul subframe in edge is a kind of among Format 1, Format 1a and the Format1b.

The demodulation pilot frequency information translation that modular converter 20 need transmit on the PUCCH of the up backhaul subframe in edge comprises for the demodulation pilot frequency complex sequences:

Generate basic sequence by the method identical with the LTE technical specification, basic sequence forms reference symbol sequence by the circulation displacement factor, selects for use the time domain orthogonal sequence spreading that reference symbol sequence is carried out the time domain expansion, promptly forms the demodulation pilot frequency complex sequences.

Modular converter 20 need be at the edge PUCCH data information transmitted of up backhaul subframe be converted to the data complex sequences and comprise:

20 pairs of modular converters need be at the edge PUCCH data information transmitted of up backhaul subframe encode and modulation operations, form modulation symbol (such as the corresponding ACK/NACK information of each code word of downlink transfer, standard is supported two code words at most at present, the ACK information of each code word correspondence is encoded to 1, nack message is encoded to 0, form 1bit or 2bits coded message during single codeword, the coded message that forms is modulated into 1 modulation symbol according to the modulating mode of table 2), and modulation symbol carried out the expansion of frequency domain and time domain, form N time domain data complex sequences, further in the process that forms the time domain data complex sequences, can also carry out other operations such as scrambling;

Wherein N is a positive integer, and N is not more than the quantity of the first available SC-FDMA symbol in the first up backhaul time slot, and the first up backhaul time slot is the time slot that comprises GP in the up backhaul subframe in edge.

Further, N also equals the length that time domain is expanded the quadrature spread sequence that is adopted.

Accordingly, if two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot (such as Fig. 2 B), then repeating mapping is to the individual first available SC-FDMA symbol of the N in each first up backhaul time slot respectively with N time domain data complex sequences for mapping block 30, and a data complex sequences is mapped to one first available SC-FDMA symbol;

If two time slots that comprise in the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot, wherein the second up backhaul time slot is the time slot (such as Fig. 2 C) that does not comprise GP in the up backhaul subframe in edge, then mapping block 30 is mapped to N time domain data complex sequences on one first N in the up backhaul time slot the first available SC-FDMA symbol, and a data complex sequences is mapped to one first available SC-FDMA symbol.

In specific implementation process, the mode that modular converter 20 is converted to the data complex sequences with data message has a variety of, enumerates several below.

Mode one, as shown in Figure 3A, the SC-FDMA symbol adopts conventional CP, and the both sides of the up backhaul subframe in edge are the up backhaul subframe of right and wrong (being that two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot) all.First SC-FDMA symbol of first time slot of the up backhaul subframe in edge and last SC-FDMA symbol of second time slot are as GP.

Concrete, 20 pairs of data messages of modular converter are encoded and operation such as modulation, form modulation symbol.

Because each first up backhaul time slot has 3 first available SC-FDMA symbols, so the first available SC-FDMA symbol that needs the data complex sequences after the conversion to take can not be greater than 3.

Then (such as selecting length for use is 12 random sequence to the symbol after 20 pairs of modulation of modular converter through frequency domain spread spectrum, multiply by modulation symbol, length of each modulation symbol formation is 12 complex sequences), and to adopt length be that 3 time domain orthogonal sequence spreading carries out time domain expansion (sequence is as shown in table 4), forms 3 time domain data complex sequences.

Accordingly, mapping block 30 is mapped to 3 time domain data complex sequences respectively on 6 SC-FDMA symbols in two time slots, that is to say 3 time domain data complex sequences are mapped on 3 SC-FDMA symbols in the time slot, again these 3 time domain data complex sequences are mapped on 3 SC-FDMA symbols in another time slot (promptly the information of two slot transmission is identical).The position that DMRS (i.e. RS among the figure) occupies can be according to the position of stipulating in the LTE technical specification.

Need to prove that the position that DMRS occupies among the figure just illustrates, also can change the position that DMRS occupies as required.

Mode two, shown in Fig. 3 B, the SC-FDMA symbol adopts expansion CP, the both sides of the up backhaul subframe in edge are the up backhaul subframe of right and wrong (being that two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot) all.First SC-FDMA symbol of first time slot of the up backhaul subframe in edge and last SC-FDMA symbol of second time slot are as GP.

The difference of Fig. 3 B and Fig. 3 A is, the SC-FDMA symbol of Fig. 3 B adopts expansion CP (being that 6 SC-FDMA symbols are arranged in each time slot), two second available SC-FDMA symbols (in each first up backhaul time slot of Fig. 3 A three second available SC-FDMA symbols being arranged) are then arranged in each first up backhaul time slot of Fig. 3 B, the processing mode of the modular converter 20 of Fig. 3 B is identical with the processing mode of the modular converter 20 of Fig. 3 A, does not repeat them here.

Mode three, shown in Fig. 3 C, the SC-FDMA symbol adopts conventional CP, the up backhaul subframe of side right and wrong of the up backhaul subframe in edge (being that two time slots that comprise in the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot).If the GP position is arranged in first time slot of the up backhaul subframe in edge, first SC-FDMA symbol that then takies first time slot is as GP; If the GP position is arranged in second time slot of the up backhaul subframe in edge, last the SC-FDMA symbol that then takies second time slot is as GP.

Owing in the first up backhaul time slot 3 first available SC-FDMA symbols are arranged, the first available SC-FDMA symbol that the data complex sequences after the conversion takies in the first up backhaul time slot can not be greater than 3.

Then for the first up backhaul time slot, the symbol after 20 pairs of modulation of modular converter is through frequency domain spread spectrum, and to adopt length be that 3 time domain orthogonal sequence spreading carries out time domain expansion (sequence is as shown in table 4), forms 3 time domain data complex sequences.

Accordingly, mapping block 30 is mapped to 3 time domain data complex sequences on 3 SC-FDMA symbols in the first up backhaul time slot.

The position that DMRS occupies can be according to the position of stipulating in the LTE technical specification.

For the second up backhaul time slot, modular converter 20 can adopt the mode of stipulating in the LTE technical specification to handle, be that 12 ZC sequence spread spectrum and length are that 4 time domain orthogonal sequence spreading carries out the time domain expansion with length promptly, the expansion back forms 4 time domain data complex sequences; Accordingly, mapping block 30 is mapped in 4 time domain data complex sequences on 4 SC-FDMA symbols of the second up backhaul time slot.

Certainly, for the second up backhaul time slot, modular converter 20 also can be handled the second up backhaul time slot according to the processing mode of the first up backhaul time slot, and the such second up backhaul time slot just has at least one first available SC-FDMA symbol and do not carry the time domain data complex sequences;

Accordingly, mapping block 30 is mapped to 3 time domain data complex sequences on 3 SC-FDMA symbols in the second up backhaul time slot, that is to say that the information of two slot transmission is identical.

Wherein, the position that occupies of DMRS can be according to the position of stipulating in the LTE technical specification.

Mode four, shown in Fig. 3 D, the SC-FDMA symbol adopts expansion CP, the up backhaul subframe of side right and wrong of the up backhaul subframe in edge (being that two time slots that comprise in the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot).If the GP position is arranged in first time slot of the up backhaul subframe in edge, first SC-FDMA symbol that then takies first time slot is as GP; If the GP position is arranged in second time slot of the up backhaul subframe in edge, last the SC-FDMA symbol that then takies second time slot is as GP.

The difference of Fig. 3 D and Fig. 3 C is, the SC-FDMA symbol of Fig. 3 D adopts expansion CP (being that 6 SC-FDMA symbols are arranged in each time slot), two second available SC-FDMA symbols (in each first up backhaul time slot of Fig. 3 C three second available SC-FDMA symbols being arranged) are then arranged in each first up backhaul time slot of Fig. 3 C, the processing mode of the modular converter 20 of Fig. 3 D is identical with the processing mode of the modular converter 20 of Fig. 3 C, does not repeat them here.

Need to prove, the embodiment of the invention is not limited to convert to the mode of 3 time domain data complex sequences, all is suitable for the embodiment of the invention as long as the number of the time domain data complex sequences after can guaranteeing to change into is not more than the mode of the quantity of the first available SC-FDMA symbol in the time slot.

Wherein, the PUCCH form of the up backhaul subframe in edge is a kind of among Format 2, Format 2a and the Format2b.

Generate basic sequence by the method identical with the LTE technical specification, basic sequence forms reference symbol sequence by the circulation displacement factor, selects for use the time domain orthogonal sequence spreading that reference symbol sequence is carried out the time domain expansion, promptly forms the demodulation pilot frequency complex sequences.If Format 2a or 2b, be used for the mixed transport of CQI and ACK/NACK, ACK/NACK's transmits on the secondary series demodulation pilot frequency, and the modulation symbol of ACK/NACK multiply by the secondary series reference symbol as the factor when reference symbol sequence is carried out the time domain orthogonal expansion.

To need be at the edge PUCCH data information transmitted of up backhaul subframe encode (such as uncoded data information sequence, the number of bits that sequence comprises is A, through (B, A) to form length be the coded sequence of B to chnnel coding, coding method is

I=0,1,2 ..., B-1, wherein M _{I, n}Be basic sequence, as shown in table 9), coded sequence formed;

Coded sequence is modulated, formed M modulation symbol, wherein M is a positive integer, and M is not more than the first available SC-FDMA symbol quantity in the up backhaul subframe in edge;

Modulation symbol is carried out frequency domain expansion, form M data complex sequences.

Concrete, 20 pairs of data messages of modular converter are encoded, and form coded sequence, and length is X;

Adopt the predetermined modulation mode to modulate to coded sequence, form M modulation symbol, and modulation symbol is carried out frequency domain expansion, form M data complex sequences;

Wherein, the order of modulation of predetermined modulation mode is s, and promptly s coded-bit is modulated to a modulation symbol; S, M, N is positive integer, and M is the first available SC-FDMA symbol quantity that is not more than in the up backhaul subframe in edge, and satisfies X=s*M;

Accordingly, mapping block 30 is mapped to M data complex sequences on M the first available SC-FDMA symbol in the up backhaul subframe in edge, and a data complex sequences is mapped to one first available SC-FDMA symbol.

Because each data complex sequences all needs one first available SC-FDMA symbols carry, can not be so form the number of data complex sequences greater than the quantity of the first available SC-FDMA symbol in the up backhaul subframe in edge.

Wherein, modular converter 20 can be when encoding, and reduces the length of coded sequence, such as regulation in the LTE technical specification adopt (20, A) encode, A is the length of data message, the number that then forms the data complex sequences is 10.

If have only 8 available first available SC-FDMA symbols carry now, then adopt (16, A) to encode, the number that forms the data complex sequences is 8.

Same, when modulating, can change the modulation system that presets, thereby change the number of the modulation symbol that forms, and then change the number that forms the data complex sequences.

Certainly, also can change the length and the modulation system of coded sequence simultaneously, thereby make the number of the data complex sequences of formation can satisfy the quantity of the first available SC-FDMA symbol.

In specific implementation process, the mode that modular converter 20 is converted to the data complex sequences with data message has a variety of, is that example describes with the length that changes coded sequence below.

Mode one, shown in Fig. 4 A, the SC-FDMA symbol adopts conventional CP, the both sides of the up backhaul subframe in edge are the up backhaul subframe of right and wrong (being that two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot) all.First SC-FDMA symbol of first time slot of the up backhaul subframe in edge and last SC-FDMA symbol of second time slot are as GP.

Owing in the up backhaul subframe in edge 8 first available SC-FDMA symbols are arranged, the first available SC-FDMA symbol that the data complex sequences after the conversion takies in the up backhaul subframe in edge can not be greater than 8.

Concrete, the data message employing that 20 pairs of length of modular converter are A (16, coded system A), promptly the bit sequence behind the coding is b ₀, b ₁, b ₂, b ₃..., b _B-1, B=16 wherein, and

I=0,1,2 ..., B-1, M _InValue referring to table 9;

Formation length in coding back is 16 coded sequence, and modulation forms 8 symbols through QPSK, carries out frequency domain spread spectrum then, forms 8 data complex sequences;

Accordingly, mapping block 30 is mapped in 8 data complex sequences on 8 the first available SC-FDMA symbols of the up backhaul subframe in edge, and this moment can be with the multiplexing identical resource of macro UEs.The position that DMRS occupies can be according to the position of stipulating in the LTE technical specification.

Further, in order to keep the demodulation performance of DMRS, DMRS is mapped in the 3rd SC-FDMA symbol with the row of first in first time slot, second interior secondary series DMRS of time slot is mapped on the 5th the SC-FDMA symbol, shown in Fig. 4 B, this moment, network equipment can not be with the multiplexing identical resource of macro UEs.

That is to say that the second available SC-FDMA symbol comprises: second and the 5th SC-FDMA symbol of second first up backhaul time slot in the 3rd and the 6th the up backhaul subframe of SC-FDMA symbol and edge of first first up backhaul time slot in the up backhaul subframe in edge.

Mode two, shown in Fig. 4 C, the SC-FDMA symbol adopts expansion CP, the both sides of the up backhaul subframe in edge are the up backhaul subframe of right and wrong (being that two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot) all.First SC-FDMA symbol of first time slot of the up backhaul subframe in edge and last SC-FDMA symbol of second time slot are as GP.

The difference of Fig. 4 C and Fig. 4 A is, the SC-FDMA symbol of Fig. 4 C adopts expansion CP (being that 6 SC-FDMA symbols are arranged in each time slot), one second available SC-FDMA symbol (in each first up backhaul time slot of Fig. 4 A two second available SC-FDMA symbols being arranged) is then arranged in each first up backhaul time slot of Fig. 4 C, the processing mode of the modular converter 20 of Fig. 4 C is identical with the processing mode of the modular converter 20 of Fig. 4 A, does not repeat them here.

Because under the situation of expansion CP, format 2a and format 2b can't work, format 2 has a row pilot tone in one first up backhaul time slot, 4 first available SC-FDMA symbols can be used, under the situation that does not change the DMRS position, network equipment can be with the multiplexing identical resource of macro UEs.

Further, in order to keep the demodulation performance of DMRS, the DMRS in first time slot is mapped in the 4th SC-FDMA symbol, second interior DMRS of time slot is mapped on the 3rd the SC-FDMA symbol, shown in Fig. 4 D, this moment, network equipment can not be with the multiplexing identical resource of macro UEs.

That is to say that the second available SC-FDMA symbol comprises: the 3rd SC-FDMA symbol of second first up backhaul time slot in the 4th the up backhaul subframe of SC-FDMA symbol and edge of first first up backhaul time slot in the up backhaul subframe in edge.

Mode three, shown in Fig. 4 E, the SC-FDMA symbol adopts conventional CP, the up backhaul subframe of side right and wrong of the up backhaul subframe in edge (being that two time slots that comprise in the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot).If the GP position is arranged in first time slot of the up backhaul subframe in edge, first SC-FDMA symbol that then takies first time slot is as GP; If the GP position is arranged in second time slot of the up backhaul subframe in edge, last the SC-FDMA symbol that then takies second time slot is as GP.

Owing in the up backhaul subframe in edge 9 first available SC-FDMA symbols are arranged, the first available SC-FDMA symbol that the data complex sequences after the conversion takies in the up backhaul subframe in edge can not be greater than 9.

Concrete, the data message employing that 20 pairs of length of modular converter are A (18, coded system A), promptly the bit sequence behind the coding is b ₀, b ₁, b ₂, b ₃..., b _B-1, B=18 wherein, and

I=0,1,2 ..., B-1, the value of Min is referring to table 9;

Formation length in coding back is 18 coded sequence, and modulation forms 9 symbols through QPSK, carries out frequency domain spread spectrum then, forms 9 data complex sequences;

Accordingly, mapping block 30 is mapped in 9 data complex sequences on 9 the first available SC-FDMA symbols of the up backhaul subframe in edge, and this moment can be with the multiplexing identical resource of macro UEs.

Further, in order to keep the DMRS performance, if first time slot of the up backhaul subframe in edge is the time slot that has GP to consume, the first row DMRS is mapped in the 3rd symbol; If second time slot of the up backhaul subframe in edge is the time slot that has GP to consume, secondary series DMRS is mapped in the 5th symbol, and shown in Fig. 4 F, this moment, network equipment can not be with the multiplexing identical resource of macro UEs.

That is to say that if the first up backhaul time slot is positioned at first time slot of the up backhaul subframe in edge, the second available SC-FDMA symbol comprises:

The the 3rd and the 6th SC-FDMA symbol of the first up backhaul time slot in the up backhaul subframe in edge;

If the first up backhaul time slot is positioned at second time slot of the up backhaul subframe in edge, the second available SC-FDMA symbol comprises:

Second and the 5th SC-FDMA symbol of the first up backhaul time slot in the up backhaul subframe in edge.

Mode four, shown in Fig. 4 G, the SC-FDMA symbol adopts expansion CP, the up backhaul subframe of side right and wrong of the up backhaul subframe in edge (being that two time slots that comprise in the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot).If the GP position is arranged in first time slot of the up backhaul subframe in edge, first SC-FDMA symbol that then takies first time slot is as GP; If the GP position is arranged in second time slot of the up backhaul subframe in edge, last the SC-FDMA symbol that then takies second time slot is as GP.

The difference of Fig. 4 G and Fig. 4 E is, the SC-FDMA symbol of Fig. 4 G adopts expansion CP (being that 6 SC-FDMA symbols are arranged in each time slot), one second available SC-FDMA symbol (in each first up backhaul time slot of Fig. 4 E two second available SC-FDMA symbols being arranged) is then arranged in each first up backhaul time slot of Fig. 4 G, the processing mode of the modular converter 20 of Fig. 4 G is identical with the processing mode of the modular converter 20 of Fig. 4 E, does not repeat them here.

Further, in order to keep the performance of DMRS, if first time slot of the up backhaul subframe in edge is the time slot that has GP to consume, the DMRS of this time slot is mapped on the 4th the SC-FDMA symbol; If second time slot of the up backhaul subframe in edge is the time slot that has GP to consume, the DMRS of this time slot is mapped on the 3rd the SC-FDMA symbol, and shown in Fig. 4 H, this moment, network equipment can not be with the multiplexing identical resource of macro UEs.

That is to say that if the first up backhaul time slot is positioned at first time slot of the up backhaul subframe in edge, the second available SC-FDMA symbol comprises: the 4th SC-FDMA symbol of the first up backhaul time slot;

If the first up backhaul time slot is positioned at second time slot of the up backhaul subframe in edge, the second available SC-FDMA symbol comprises: the 3rd SC-FDMA symbol of the first up backhaul time slot.

Need to prove, the embodiment of the invention is not limited to convert to the mode of 8 or 9 time domain data complex sequences, all is suitable for the embodiment of the invention as long as the number of the time domain data complex sequences after can guaranteeing to change into is not more than the mode of the quantity of the first available SC-FDMA symbol in the up backhaul subframe in edge.

Wherein, the mode that changes the data complex sequences quantity after changing can also be used (the second available SC-FDMA symbol in a part first up backhaul time slot is as the first available SC-FDMA symbol) with the mode that reduces DMRS, thereby further make the quantity Matching of the multiple ordinal number amount of data and the first available SC-FDMA symbol after the conversion, promptly the data after the conversion are answered the quantity that the ordinal number amount is not more than the first available SC-FDMA symbol.

The PUCCH form of the up backhaul subframe in edge is a kind of among Format 1, Format 1a and the Format 1b, and then the network equipment of the embodiment of the invention can further include: first processing module 40.

First processing module 40 was used for before modular converter 20 is converted to the data complex sequences with data message, and the second available SC-FDMA symbol of the part in the first up backhaul time slot as the first available SC-FDMA symbol, is carried the data complex sequences.

In specific implementation process, can be when channel configuration with the second available SC-FDMA symbol of the part in the first up backhaul time slot as the first available SC-FDMA symbol, store in the network equipment of the embodiment of the invention then in advance; Also can confirm that by first processing module 40 which second available SC-FDMA symbol can be used as the first available SC-FDMA symbol by the network equipment of high level by the signaling embodiment of the invention.

For the PUCCH form of the up backhaul subframe in edge is the mode one among Format 1, Format 1a and the Format1b and the situation of mode two, two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot, so can be with one the second available SC-FDMA symbol (promptly being used to carry the symbol of DMRS) in each first up backhaul time slot as the first available SC-FDMA symbol.

Preferable, if the SC-FDMA symbol of the up backhaul subframe in edge adopts conventional CP (being mode one), shown in Fig. 5 A, in first time slot, two row DMRS are mapped in respectively on the 4th and the 5th the SC-FDMA symbol, in second time slot, two row DMRS are mapped on the 3rd and the 4th the SC-FDMA symbol.Each time slot has 4 SC-FDMA symbols to use, and other are according to the LTE technical scheme.That is to say, except that as the first available SC-FDMA symbol, the remainder symbol of the second available SC-FDMA symbol comprises: in two first up backhaul time slots, and the 4th and the 3rd and the 4th SC-FDMA symbol of the 5th SC-FDMA symbol and second first up backhaul time slot of first first up backhaul time slot.

If the SC-FDMA symbol of the up backhaul subframe in edge adopts expansion CP (being mode two), shown in Fig. 5 B, each time slot only insert one row DMRS, and be mapped in each time slot can with the SC-FDMA symbol the middle symbol on, other are according to the LTE technical scheme.

That is to say, except that as the first available SC-FDMA symbol, the remainder symbol of the second available SC-FDMA symbol comprises: the 3rd SC-FDMA symbol of the 4th SC-FDMA symbol of first first up backhaul time slot and second first up backhaul time slot.

For the PUCCH form of the up backhaul subframe in edge is the mode three among Format 1, Format 1a and the Format1b and the situation of mode four, two time slots of the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot, so can be with one the second available SC-FDMA symbol (promptly being used to carry the symbol of DMRS) in the first up backhaul time slot as the first available SC-FDMA symbol.

Preferable, if the SC-FDMA symbol of the up backhaul subframe in edge adopts conventional CP (being mode three), shown in Fig. 5 C, interior DMRS number and the position of time slot that does not have GP to consume remains unchanged, the interior DMRS of time slot that has GP to consume is reduced to two row, and is mapped on middle two symbols of available SC-FDMA symbol.Two time slots that have GP to consume all have 4 SC-FDMA symbols to can be used for transmitting the data complex sequences, and other are according to the LTE technical specification.

That is to say, except that as the first available SC-FDMA symbol, the remainder symbol of the second available SC-FDMA symbol comprises: if the first up backhaul time slot is positioned at first time slot of the up backhaul subframe in edge, and the 4th and the 5th SC-FDMA symbol of the first up backhaul time slot; If the first up backhaul time slot is positioned at second time slot of the up backhaul subframe in edge, the 3rd and the 4th SC-FDMA symbol of the first up backhaul time slot.

If the SC-FDMA symbol of the up backhaul subframe in edge adopts expansion CP (being mode four), shown in Fig. 5 D, interior DMRS number and the position of time slot that does not have GP to consume remains unchanged, and the time slot that has GP to consume only keeps a row DMRS, is mapped on the middle symbol of available SC-FDMA symbol.

That is to say, except that as the first available SC-FDMA symbol, the remainder symbol of the second available SC-FDMA symbol comprises: if the first up backhaul time slot is positioned at first time slot of the up backhaul subframe in edge, and the 4th SC-FDMA symbol of the first up backhaul time slot; If the first up backhaul time slot is positioned at second time slot of the up backhaul subframe in edge, the 3rd SC-FDMA symbol of the first up backhaul time slot.

Because among Format 2, Format 2a and the Format 2b, if the SC-FDMA symbol adopts expansion CP, then have only in each time slot of Format 2 one second available SC-FDMA symbol is arranged, Format2a and Format 2b do not have the second available SC-FDMA symbol, if the neither one second available SC-FDMA symbol in the time slot can occur so reduce by one second available SC-FDMA symbol again, thereby can not transmit the demodulation pilot frequency complex sequences, if adopt expansion CP based on this SC-FDMA symbol, then do not adopt the scheme that reduces DMRS.

If the up backhaul sub-frame formats in edge is Format 2, and the SC-FDMA symbol of the up backhaul subframe in edge adopts conventional CP, comprise two first up backhaul time slots in the up backhaul subframe in edge or comprise one first up backhaul time slot and one second up backhaul time slot, the network equipment of the embodiment of the invention can further include: second processing module 50.

Second processing module 50 was used for before modular converter 20 is converted to the data complex sequences with data message, and the second available SC-FDMA symbol of the part in the first up backhaul time slot as the first available SC-FDMA symbol, is used to carry the data complex sequences.

PUCCH form for the up backhaul subframe in edge is Format 2 situations, two time slots of the up backhaul subframe in edge all are the first up backhaul time slot, so can be with one the second available SC-FDMA symbol (promptly being used to carry the symbol of DMRS) in each first up backhaul time slot as the first available SC-FDMA symbol.

Preferable, as shown in Figure 6A, each time slot only inserts a row DMRS, and pilot frequency locations is positioned on the 4th the SC-FDMA symbol of each time slot, other 5 SC-FDMA symbols can be used for CQI (Channel Quality Indicator, channel quality indication) transmission, and scheme is with the LTE technical specification.Because have only a row DMRS, network equipment and macro UEs can not be in identical PRB multiplexed resource, the resource allocation of the two is positioned at different PRB.This scheme can't be suitable for format 2a and format 2b, because if will transmit CQI and ACK/NACK simultaneously, ACK/NACK need transmit on secondary series DMRS.

That is to say that except that as the first available SC-FDMA symbol, the remainder symbol of the second available SC-FDMA symbol comprises: the 4th SC-FDMA symbol of the first up backhaul time slot.

PUCCH form for the up backhaul subframe in edge is the situation of the mode three among Format 2, Format 2a and the Format2b, two time slots of the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot, so can be with one the second available SC-FDMA symbol (promptly being used to carry the symbol of DMRS) in the first up backhaul time slot as the first available SC-FDMA symbol.

Preferable, shown in Fig. 6 B, in the time slot that has GP to consume, insert a row DMRS, be mapped in the 4th SC-FDMA symbol, the interior DMRS of the time slot that does not have GP to consume remains unchanged.Having 10 SC-FDMA symbols in the subframe can use, and other are according to the LTE technical specification.Because in the time slot that has GP to consume, have only a row DMRS, network equipment and macro UEs can not be in identical PRB multiplexed resource, the resource allocation of the two is positioned at different PRB.If transmit CQI and ACK/NACK simultaneously, transmit on the only multiplexing secondary series DMRS in not having GP consumption time slot of ACK/NACK.

Need to prove, the embodiment of the invention is not limited to the position and the quantity of the above-described second available SC-FDMA symbol, as long as can guarantee to have in each time slot the second available SC-FDMA symbol, other all are suitable for the embodiment of the invention with any mode as the first available SC-FDMA symbol and other positions of the second available SC-FDMA symbol.

Wherein, when the adjacent sub-frame of a up backhaul subframe is up backhaul subframe, do not need to switch GP, the PUCCH of this subframe is identical with the LTE technology, does not need redesign.

For formats 2/2a/2b, can not adopt the frequency hopping mode to transmit in the such scheme, promptly in two time slots, PUCCH is positioned at the same side of frequency band.If do not adopt the frequency hopping mode, network equipment can't be with the multiplexing identical resource of macro UEs.Therefore, for such scheme, if network equipment can in order to reduce design complexity, adopt the frequency hopping mode with macro UEs multiplexed resource; If network equipment can not then adopt frequency hopping or non-frequency hopping mode all can with the multiplexing same asset of macro UEs.

Then the network equipment of the embodiment of the invention can further include: transport module 60.

Transport module 60 is used for after mapping block 30 is mapped to data complex sequences and pilot tone complex sequences on the SC-FDMA symbol, adopts frequency hopping mode or non-frequency hopping mode to transmit the uplink information that carries on the SC-FDMA symbol.

For formats 1/1a/1b, in the LTE technical specification, PDSCH (Physical Downlink SharedChannel, physical down link sharing channel) transmission is divided into semi-persistent scheduling transmission and dynamic dispatching transmission, if be the semi-persistent scheduling transmission, UE detects the PDCCH less than correspondence in the subframe that receives PDSCH.Semi-persistent scheduling and dynamic dispatching all have corresponding ACK/NACK transmission, and therefore corresponding PUCCH resource allocation is all arranged.If corresponding PUCCH adopts identical format transmission, the PUCCH resource occupation of semi-persistent scheduling PDSCH correspondence is distributed to the initial part of this format resource, the PUCCH resource location of each UE correspondence obtains by high-level signaling, thereafter be the PUCCH resource of dynamic dispatching PDSCH correspondence, the PUCCH resource location of each UE correspondence distributes corresponding CCE numbering binding with DCI.Above-mentioned two kinds of PUCCH resources are mutually orthogonal, shown in Fig. 7 A.

For network equipment, the resource of its PDSCH correspondence can't multiplexing UE PDSCH correspondence the PUCCH resource, in order not influence the PUCCH resource of macro UEs semi-persistent scheduling PDSCH and dynamic dispatching PDSCH correspondence, can between two kinds of PUCCH resources, repartition out the PUCCH resource that a blank resource is used for network equipment PDSCH correspondence.Realizing method is, the PUCCH resource location of semi-persistent scheduling PDSCH correspondence is constant, dynamically the original position index of the PUCCH resource of PDSCH correspondence adds an offset parameter, this parameter is specified by high level, formed a new white space like this between the PUCCH resource of semi-static PDSCH and dynamic PDSCH correspondence, this white space is the PUCCH resource of distributing to network equipment PDSCH correspondence.With the fdd mode is example, and the PUCCH resource location index of dynamic dispatching PDSCH correspondence is

Wherein,

Be the PUCCH resource that network equipment is used for transmitting HARQ-ACK, n _CCEBe the numbering that is used to transmit first control channel unit CCE of corresponding Downlink Control Information DCI,

Be the parameter of high-rise configuration, this offset parameter can lie in

In, so dynamic dispatching macro UEs is unaware of the PUCCH resource of distributing to network equipment.Resource allocation is shown in Fig. 7 B.When then the up backhaul sub-frame formats in edge was a kind of among Format 1,1a and the 1b, the network equipment of the embodiment of the invention can further include: the first resource subframe determination module 70.

The first resource subframe determination module 70, be used for can not multiplexing grand user terminal at network equipment resource, and subframe determination module 10 is determined after the up backhaul subframe in edge, according to the offset parameter of receiving from high level, determine to distribute to the resource original position of self PUCCH, wherein the value of offset parameter is not less than the end position side-play amount of the grand user terminal of semi-persistent scheduling institute Resources allocation.

For formats 2/2a/2b, in the LTE technical specification, a plurality of UEs adopt identical PUCCH channel architecture, the mode multiplexed resource that can divide by sign indicating number in identical PRB.For network equipment and macro UEs, if adopt identical channel architecture, can be in identical PRB multiplexed resource; If adopt different channel architectures, then network equipment and macro UEs can't be in identical PRB multiplexed resource, the resource of the two is positioned at different PRB, shown in Fig. 7 C; The PUCCH resource location of network equipment obtains by high-level signaling.When then the up backhaul sub-frame formats in edge was a kind of among Format 2,2a and the 2b, the network equipment of the embodiment of the invention can further include: the second resource subframe determination module 80.

The second resource subframe determination module 80, be used for can not multiplexing grand user terminal at network equipment resource, and subframe determination module 10 is determined after the up backhaul subframe in edge, according to the location parameter of receiving from high level, determine to distribute to the resource location of self PUCCH, the PRB at resource place that wherein distributes to network equipment PUCCH is different with the PRB at the resource place of distributing to grand user terminal PUCCH.

The network equipment of the embodiment of the invention can be a RN equipment, also can be other equipment of network side, can also be the new equipment of network side.

As shown in Figure 8, the method for embodiment of the invention transmission information comprises the following steps:

Step 801, network equipment are determined the up backhaul subframe in edge, and wherein the part SC-FDMA symbol in the up backhaul subframe in edge is GP.

Step 802, network equipment need be at the edge PUCCH data information transmitted and the demodulation pilot frequency information of up backhaul subframe be converted to data complex sequences and demodulation pilot frequency complex sequences respectively, wherein the SC-FDMA symbol quantity that takies of data complex sequences is not more than the quantity of the first available SC-FDMA symbol that is used to carry the data complex sequences among the PUCCH.

Step 803, network equipment are mapped to data complex sequences and demodulation pilot frequency complex sequences on the first available SC-FDMA symbol among the PUCCH respectively and are used to carry the second available SC-FDMA symbol of demodulation pilot frequency complex sequences among the PUCCH.

In the step 801, if up backhaul subframe adjacent with non-up back haul link subframe (being the up backhaul subframe in edge) then needs to take the part SC-FDMA symbol of up backhaul subframe as GP.

Be arranged in the up backhaul subframe in edge of front, first SC-FDMA symbol that takies first time slot is as GP; Be arranged in the up backhaul subframe in edge of back, last (promptly the 7th) the SC-FDMA symbol that takies second time slot is as GP.

Comprise three kinds of SC-FDMA symbols in the up backhaul subframe in edge, be respectively the first available SC-FDMA symbol that is used to carry the data complex sequences, be used for carrying the second available SC-FDMA symbol (being the DMRS of Fig. 2 B and Fig. 2 C) of demodulation pilot frequency complex sequences and as the SC-FDMA symbol of GP.

In the step 802, the demodulation pilot frequency information translation that network equipment need transmit on the PUCCH of the up backhaul subframe in edge comprises for the demodulation pilot frequency complex sequences:

Network equipment need be at the edge PUCCH data information transmitted of up backhaul subframe be converted to the data complex sequences and comprise:

Network equipment to need be at the edge PUCCH data information transmitted of up backhaul subframe encode and modulation operations, further can also carry out other operations such as scrambling, form modulation symbol, and modulation symbol is carried out frequency domain and time domain expansion, form N time domain data complex sequences;

Wherein N is a positive integer, and N is not more than the quantity of the first available SC-FDMA symbol in the first up backhaul time slot, and the first up backhaul time slot is the time slot that comprises GP in the up backhaul subframe in edge.Further, N also equals the length that time domain is expanded the quadrature spread sequence that is adopted.

Accordingly, if two time slots that comprise in the up backhaul subframe in edge are the first up backhaul time slot (such as Fig. 2 B), then in the step 803, repeating mapping is to the individual first available SC-FDMA symbol of the N in each first up backhaul time slot respectively with N time domain data complex sequences for network equipment, and a data complex sequences is mapped to one first available SC-FDMA symbol;

If two time slots that comprise in the up backhaul subframe in edge are one first up backhaul time slot and one second up backhaul time slot, wherein the second up backhaul time slot is the time slot (such as Fig. 2 C) that does not comprise GP in the up backhaul subframe in edge, then in the step 803, network equipment is mapped to N time domain data complex sequences on one first N in the up backhaul time slot the first available SC-FDMA symbol, and a data complex sequences is mapped to one first available SC-FDMA symbol.

In the step 802, network equipment has the mode that data message is converted to the data complex sequences a variety of, concrete every kind of mode and the PUCCH form of the up backhaul subframe in the edge of embodiment of the invention network equipment are that the mode one～mode four among Format 1, Format 1a and the Format 1b is identical, do not repeat them here.

To need be at the edge PUCCH data information transmitted of up backhaul subframe encode, form coded sequence;

Concrete, network equipment is encoded to data message, forms coded sequence, and length is X;

Accordingly, network equipment is mapped to M data complex sequences on M the first available SC-FDMA symbol in the up backhaul subframe in edge in the step 803, and a data complex sequences is mapped to one first available SC-FDMA symbol.

Wherein, network equipment can be when encoding in the step 802, reduces the length of coded sequence, such as regulation in the LTE technical specification adopt (20, A) encode, A is the length of data message, the number that then forms the data complex sequences is 10.

In specific implementation process, network equipment has the mode that data message is converted to the data complex sequences a variety of, concrete every kind of mode and the PUCCH form of the up backhaul subframe in the edge of embodiment of the invention network equipment are that the mode one～mode four among Format 2, Format 2a and the Format 2b is identical, do not repeat them here.

Wherein, the mode that changes the data complex sequences quantity after changing can also be used (soon a part second available SC-FDMA symbol in the first up backhaul time slot is as the first available SC-FDMA symbol) with the mode that reduces DMRS, thereby further make the quantity Matching of the multiple ordinal number amount of data and the first available SC-FDMA symbol after the conversion, promptly the data after the conversion are answered the quantity that the ordinal number amount is not more than the first available SC-FDMA symbol.

The PUCCH form of the up backhaul subframe in edge is a kind of among Format 1, Format 1a and the Format 1b, can further include before the step 802:
