Embodiment

In LTE system, the mode of upstream control signaling and upstream data multiplexing radio frames is as shown in Figure 1.Channel coding process when upstream control signaling and upstream data are multiplexed in LTE system is as shown in Figure 2, upstream data is with TB (Transport Block, transmission block) form transmission, TB passes through CRC attachment (CRC addition), Code block segmentation (code block segmentation) and Code blockCRC attachment (sub-block CRC additions), Channel coding (channel coding), Rate matching (rate-matched), Code block concatenation (code block synthesis) carry out the multiplexing of upstream data and control signaling with CQI/PMI after coding afterwards, finally by channel interleaving the ACK/NACK after coding, RI and upstream data are multiplexed together.PUSCH transmission mode in LTE system is as shown in figure 3, PUSCH only corresponds to a transmission block or streams of code words.

Above-mentioned uplink control signaling cataloged procedure is specific as follows：

First, target length is calculated according to given formula, for ACK/NACK and RI, target length is calculated by formula one.

Formula one

For CQI, target length is calculated by formula two.

Formula two

Then target length is Q_ACK=Q_mQ ', Q_RI=Q_mQ ', Q_CQI=Q_mQ ', wherein M_sc ^PUSCHIt is the PUSCH bandwidth of present sub-frame scheduling, is represented with the number of subcarrier, N_symb ^PUSCHThe symbol numbers (relevant with CP type with SRS) of SC-FDMA when being each subframe PUSCH transmission, C, K_rRepresent to carry out transmission block sub-block number and size after code block segmentation, β_offset ^PUSCHValue be provided by base station by signaling (

Or β_offset ^RIOr β_offset ^CQI), uplink control signaling number is O (O is ACK/NACK response messages or RI signalings or CQI/PMI number), Q_mFor transmission block or the modulation system of streams of code words.

Then channel coding is carried out, ACK/NACK is identical with RI coded system, if ACK/NACK response messages or RI information are 1 bit, in the case where modulation system is QPSK, encoded infonnation is [O₀, y]；In the case where modulation system is 16QAM, encoded infonnation is [O₀, y, x, x]；In the case where modulation system is 64QAM, encoded infonnation is [O₀, y, x, x, x, x]；Wherein, O₀ACK/NACK response messages or RI signalings, x are represented, y represents to maximize the placeholder of the Euclidean distance of modulation symbol during for scrambling；If ACK/NACK response messages or RI information are 2 bit, in the case where modulation system is QPSK, encoded infonnation is [O₀, O₁, O₂, O₀, O₁, O₂,]；In the case where modulation system is 16QAM, encoded infonnation is [O₀, O₁, x, x, O₂, O₀, x, x, O₁, O₂, x, x]；In the case where modulation system is 64QAM, encoded infonnation is [O₀, O₁, x, x, x, x, O₂, O₀, x, x, x, x, O₁, O₂, x, x, x, x]；Wherein, O₀, O₁, the ACK/NACK response messages or RI information of 2 bits are represented,

X represents to maximize the placeholder of the Euclidean distance of modulation symbol during for scrambling；Due to there is a situation where that the number of ACK/NACK response messages is more than 2 bits in LTE system, such as in a tdd system, so when ACK/NACK response messages are more than 2 bit, being encoded using the coded system of (32, O).When CQI/PMI bit number is less than or equal to 11 bit, CQI is encoded using the coded system of (32, O)；Otherwise, first carry out CRC additions, then the length shown in Fig. 4 is used for 7, code check is encoded for the coded system of 1/3 tail-biting convolutional code, finally by ACK/NACK response messages, RI, the bit after CQI/PMI is encoded is repeated, untill meeting target length, the information bit after coding is designated as [q respectively₀ ^ACK, q₁ ^ACK, q₂ ^ACK...,

]、[q₀ ^CQI, q₁ ^CQI, q₂ ^CQI...,]、[q₀ ^RI, q₁ ^RI, q₂ ^RI...,

]。

The multiplexing of wherein upstream data and control signaling is exactly that the form of the modulation symbol according to this of the CQI/PMI information sum after coding cascades up, be designated as [g ₀ ⁱ,g ₁ ⁱ,g ₂ ⁱ...,

]。

The process of channel interleaving is exactly in a certain order by the ACK/NACK information bits [q after coding₀ ^ACK, q₁ ^ACK, q₂ ^ACK...,

], RI information bits [q₀ ^RI, q₁ ^RI, q₂ ^RI...,] and by data and the [g of control multiplexing₀ ⁱ, g₀ ⁱ, g₂ ⁱ...,

] be written in a virtual matrix, then virtual matrix is sequentially read according to Row Column, so as to ensure during follow-up modulation symbol to physical resource mapping, ACK/NACK, RI, CQI/PMI and data are able to be mapped on position as shown in Figure 1.The detailed process of channel interleaving is described as follows：

A virtual matrix is firstly generated, the size of virtual matrix is relevant with PUSCH resource allocation；According to the row for first writing virtual matrix, the order of the row of rear write-in virtual matrix writes since last column of virtual matrix to the first row, by the RI information bits [q after coding₀ ^RI, q₁ ^RI, q₂ ^RI...,

] precalculated position of the middle RI information of write-in virtual matrix in the form of modulation symbol；Since the position of the first row first row of virtual matrix, according to the order of Column Row, will [g ₀ ⁱ,g ₁ ⁱ,g ₂ ⁱ...,

] be written in virtual matrix, the position that RI information has been written into is skipped during write-in；According to the row for first writing virtual matrix, the order of the row of rear write-in virtual matrix writes since last column of virtual matrix to the first row, by the ACK/NACK information bits [q after coding₀ ^ACK, q₁ ^ACK, q₂ ^ACK...,] precalculated position of the middle ACK/NACK information of write-in virtual matrix in the form of modulation symbol, during write-in, if had been written on certain position [g ₀ ⁱ,g ₁ ⁱ,g ₂ ⁱ...,

], then the data symbol on the position is destroyed.Virtual matrix finally is sequentially read according to Row Column, the sequences h in modulation symbol form after being interweaved₀, h₁, h₂,,

Wherein RI precalculated position is as shown in table 1.

Table 1

The form of cyclic prefix	Row combination
		Conventional cyclic prefix	{ Isosorbide-5-Nitrae, 7,10 }
Extended cyclic prefix	{ 0,3,5,8 }

ACK/NACK precalculated position is as shown in table 2.

Table 2

The form of cyclic prefix	Row combination
		Conventional cyclic prefix	{ 2,3,8,9 }
Extended cyclic prefix	{ 1,2,6,7 }

LTE-A supports up bigger transmission rate, so the form of spatial reuse is supported in PUSCH transmission.For the PUSCH transmitted using spatial reuse form, the mapping of codeword current to layer is identical when correlation technique gives the relation of the mapping of codeword current to layer with LTE system downlink transfer, specifically maps relation as shown in table 3.

Table 3

Wherein M_symb ^layerRepresent the data volume of every layer of transmission, M_symb ⁽⁰⁾, M_symb ⁽¹⁾The upper symbolic number of each streams of code words, d are represented respectively⁽⁰⁾(i), d⁽¹⁾(i) data in each streams of code words, x are represented respectively⁽⁰⁾..., x (i)⁽³⁾(i) data of each layer of upper transmission are represented respectively.

So, there is the situation of 2 streams of code words in lte-a system during PUSCH transmission, then have the two transmission blocks or the modulation coding information of streams of code words in corresponding PDCCH control signalings, if being designated as I respectively_MCS ¹, I_MCS ²。

The situation of space division multiplexing is supported in PUSCH transmission in lte-a system, but when being a lack of a PUSCH and transmitting data using space division multiplexing mode, the transmission mechanism that upstream control signaling is transmitted on PUSCH.

In order to solve the above problems, The embodiment provides a kind of ascending control signaling transmission method, solve in PUSCH space division multiplexings, do not transmit uplink control signaling mechanism problem.

As known from Table 3, two transmission blocks or streams of code words in PUSCH may map in multiple transport layers；Embodiments of the invention are illustrated so that PUSCH includes two transport layers as an example, and PUSCH two transport layers correspond to transmission block TB1 and TB2 respectively, and corresponding modulation coding mode is respectively I_MCS ¹, I_MCS ², the code check of two transmission blocks or streams of code words is

Or β_offset ^RIOr β_offset ^CQI) value provided by base station by signaling, represent the offset of performance amount of upstream control signaling and data, uplink control signaling number is O_UCI(O_UCIIt is ACK/NACK or RI or CQI/PMI number), Q_m ¹, Q_m ²For two transmission blocks or the modulation system of streams of code words.In embodiments of the invention, row illustrates when exemplified by up signaling ACK/NACK, RI and CQI/PMI is transmitted on PUSCH, but the upstream control signaling transmitted on PUSCH is not limited to above-mentioned three kinds, and embodiments of the invention are not construed as limiting to this.

First with reference to accompanying drawing, embodiments of the invention one are introduced.
