Description

Method and system for coding uplink control information based on PUSCH transmission

Technical Field

The invention relates to the field of wireless communication, in particular to a problem of transmission of Uplink control information in a Physical Uplink Shared Channel (PUSCH).

Background

In a Long Term Evolution (LTE) system, the uplink control Information to be transmitted in uplink includes correct/incorrect response Information (ACK/NACK) and three forms reflecting downlink physical Channel State Information (CSI): channel Quality Indication (CQI), precoding Matrix indication information (PMI), and Rank indication information (RI).

In the LTE system, ACK/NACK information is transmitted in a format1/1 a/1b (PUCCH format1/1a1/b) on a Physical Uplink Control Channel (PUCCH), and transmitted on a PUSCH if a terminal (UE) needs to transmit Uplink data. The feedback of the CQI/PMI and the RI may be periodic feedback or aperiodic feedback, wherein for the CQI/PMI and the RI that are periodically fed back, if the UE does not need to send uplink data, the CQI/PMI and the RI that are periodically fed back are transmitted on a PUCCH in a format2/2a/2b (PUCCH format2/2a/2b), and if the UE needs to send uplink data, the CQI/PMI and the RI are transmitted on a PUSCH; for the CQI/PMI and RI with aperiodic feedback, the transmission is only carried out on the PUSCH.

Fig. 1 shows a schematic diagram of a multiplexing mode of uplink control information and uplink data in an LTE system, and fig. 2 shows an encoding process when multiplexing the uplink control information and the uplink data in the LTE system, where the uplink data is transmitted in the form of a Transport Block (TB), the TB is subjected to cyclic redundancy check addition (CRC attachment), Code Block segmentation (Code Block segmentation) and sub-Block CRC addition (Code Block CRC attachment), Channel coding (Channel coding), Rate matching (Rate matching), multiplexing of the uplink data and the control information with a coded CQI/PMI after Code Block synthesis (Code Block coordination), and finally multiplexing the coded ACK/NACK information and RI information with the data by Channel interleaving.

Fig. 3 shows a PUSCH transmission mode in an LTE system, and it can be seen from the figure that the PUSCH is transmitted in a single antenna form, so the PUSCH corresponds to only one transmission block, and the transmission block is encoded and multiplexed to form one code word stream, that is, the PUSCH in the LTE system has only one code word stream.

Wherein, the coding process of the control information comprises the following three steps:

calculating to obtain the number of target coding symbols of uplink control information according to a given formula, and multiplying the number by the modulation order of a transmission block to obtain the number of target coding modulation symbols;

the uplink control information comprises ACK/NACK information, RI information and CQI/PMI information, and the calculation time is divided into two cases of transmitting uplink data and control information on a PUSCH and transmitting only the control information on the PUSCH. When only control information is transmitted on the PUSCH, the number of target coding modulation symbols can be directly calculated for CQI/PMI information.

The CQI and PMI information are transmitted as one information unit, which is expressed as CQI/PMI information, and there may be only the CQI information or PMI information at the time of transmission, or both the CQI and PMI information. When calculating the target number of code symbols, the target number of code symbols for the information unit is calculated. In addition, CQI as a parameter subscript or superscript in the formulas herein is used to refer to CQI/PMI information. The ACK and NACK cases are similar, and ACK, as a parameter subscript or superscript in the formulas herein, is used to refer to ACK/NACK information.

Step two, carrying out channel coding on the control information;

the ACK/NACK and RI have the same channel coding mode, if the ACK/NACK information or RI information is 1 bit, under the condition that the modulation mode is QPSK, the information after channel coding is [ O ]₀，y](ii) a When the modulation scheme is 16QAM, the channel coded information is [ O ]₀，y，x，x](ii) a When the modulation scheme is 64QAM, the channel coded information is [ O ]₀，y，x，x，x，x](ii) a Wherein, O₀Represents ACK/NACK information or RI information, and x, y represents a placeholder for maximizing a euclidean distance of a modulation symbol when scrambling;

if the ACK/NACK information or RI information is 2 bits, the information after channel coding is [ O ] under the condition that the modulation mode is QPSK₀，O₁，O₂，O₀，O₁，O₂，](ii) a When the modulation scheme is 16QAM, the channel coded information is [ O ]₀，O₁，x，x，O₂，O₀，x，x，O₁，O₂，x，x](ii) a When the modulation scheme is 64QAM, the channel coded information is [ O ]₀，O₁，x，x，x，x，O₂，O₀，x，x，x，x，O₁，O₂，x，x，x，x](ii) a Wherein, O₀，O₁Indicating 2-bit ACK/NACK information or RI information,

(

representing an exclusive or operation), x represents a placeholder for maximizing the euclidean distance of the modulation symbols when scrambled;

in the LTE system, the number of ACK/NACK messages is greater than 2 bits, for example, in the TDD system, when the number of ACK/NACK messages is greater than 2 bits, a (32, O) coding scheme is used for channel coding.

When the bit number of the CQI/PMI is less than or equal to 11 bits, the CQI adopts a (32, O) coding mode to carry out channel coding; otherwise, CRC addition is carried out firstly, and then channel coding is carried out by adopting a coding mode of tail-biting convolutional codes with the length of 7 and the code rate of 1/3.

And step three, repeating the coded bits of the ACK/NACK information, RI and CQI/PMI channels until the number of the target coded modulation symbols is met.

The coded information bits are respectively marked as

After the coding of the control information is completed, the multiplexing of the uplink data and the control information is to concatenate the coded CQI/PMI information and the data in the form of modulation symbols, and record the result as

The channel interleaving process is to carry out the coded ACK/NACK information bits according to a certain sequence

RI information bits

And by data and control multiplexing

Writing into a virtual matrix, and reading out the virtual matrix according to the sequence of the first and the last columns, thereby ensuring the subsequent modulationIn the process of mapping the symbols to the physical resources, ACK/NACK, RI, CQI/PMI and data can be mapped to the positions shown in fig. 1, respectively.

The Long Term Evolution Advanced (LTE-a) system, which is an Evolution standard of LTE, supports a larger uplink transmission rate, so that the transmission of PUSCH supports a spatial multiplexing format. For the PUSCH transmitted in the form of spatial multiplexing, the related art gives the mapping relationship from the codeword stream to the layer, which is the same as the mapping relationship from the codeword stream to the layer in the downlink transmission of the LTE system, and the specific mapping relationship is shown in table 1:

TABLE 1 PUSCH SDMA codeword to layer mapping table in LTE-A systems

In the table, i is an index of each layer of coded modulation symbols;

indicating the amount of data transferred for each layer,

respectively representing the number of coded modulation symbols on each code word stream; d⁽¹⁾(i)，d⁽¹⁾(i) Respectively representing data on each codeword stream; x is the number of⁽⁰⁾(i)，...x⁽³⁾(i) Respectively representing the data transmitted on the various layers.

The current conclusion about the transmission of uplink control information on spatially multiplexed PUSCH is: for ACK/NACK information and RI information, the transmission is repeated on all transmission layers of two code word streams, and the time division multiplexing is carried out on all transmission layers and data, and the number of coding modulation symbols of control information on each transmission layer is the same. For CQI/PMI information, it is transmitted on one stream of codewords.

However, the prior art does not disclose how to determine the target number of coded symbols when ACK/NACK information and RI information are transmitted on each transmission layer, nor does it disclose which codeword stream the CQI/PMI selects and how to determine the target number of coded symbols when the CQI/PMI is transmitted on the codeword stream, so that the coding of uplink control information transmitted on the basis of the spatially multiplexed PUSCH cannot be realized.

Detailed Description

Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples. The invention can be used for an LTE-A system and can also be used for other communication systems with PUSCH transmission in a spatial multiplexing mode.

Example one

In this embodiment, two transmission blocks are currently configured, and both the two transmission blocks have uplink data transmission, and two codeword streams are obtained after encoding. The uplink control information is ACK/NACK information or RI information.

As shown in fig. 4, the method of this embodiment includes:

step 410, a User Equipment (UE) selects one transport block from two transport blocks;

the UE may select one transport block from the two transport blocks in one of several ways:

(1) UE selection of modulation code index in two transport blocks

If the modulation coding indexes of the two transport blocks are the same, selecting one transport block arbitrarily or selecting a default transport block;

(2) UE compares the sum of the bit numbers of each code block obtained by CRC addition, code block segmentation and subblock CRC addition of the two transmission blocks, selects a transmission block with a larger sum of the bit numbers, and randomly selects a transmission block or selects a default transmission block if the sum of the bit numbers is equal;

(3) the UE selects one transmission block with larger transmission block size from the two transmission blocks, and if the two transmission blocks have the same size, one transmission block is selected arbitrarily or a default transmission block is selected;

(4) the UE selects one transmission block from the two transmission blocks according to the downlink signaling indication;

(5) the UE and the base station appoint to fixedly select the first transmission block or the second transmission block.

Step 420, the UE calculates, according to the parameter information of the selected transport block, the size of the uplink control information, and the offset value configured in the high layer, a target number of coded symbols when the uplink control information is transmitted on each transport layer, and multiplies the target number of coded symbols by the modulation order of two transport blocks, respectively, to obtain two target numbers of coded modulation symbols, which correspond to the code word streams formed by coding the two transport blocks, respectively;

in this step, the formula for the UE to calculate the target number of code symbols is the same as the formula for the UE to calculate the target number of code symbols for uplink control information when uplink data and control information are transmitted on PUSCH in the LTE system, and the target number of code symbols per transmission layer is Q'_layerComprises the following steps:

the meaning of each parameter in the formula (1) is the same as that of each parameter in the formula (1), wherein the parameter information of the transmission block adopts the selected parameter information of the transmission block, and comprises code block information of the transmission block, bandwidth during transmission and the number of SC-FDMA symbols, and the code block information refers to the code block size and the code block number corresponding to the transmission block obtained by carrying out code block segmentation on the transmission block. The parameter information of the transport block may further include the number of transport layers corresponding to the target transport block during transmission. The size of the uplink control information refers to the number of bits of the uplink control information, and the number of check bits when performing CRC check on the CQI/PMI information and the CQI/PMI information is also included. The same parameters in the formulas of the respective embodiments indicate the same meanings.

Can define a number M of code symbolsⁱCalculatingWhen the parameter information of the transmission block adopted when the number of the target coding symbols is the parameter information of the transmission block with uplink data transmission, the following steps are carried out:

thus, the above equation can be simplified as:

wherein:

i represents the index of the transport block selected in the previous step, i is 0 or 1;

o represents the bit number of the ACK/NACK information or the RI information;

representing the bandwidth of the current sub-frame for PUSCH transmission, and representing the bandwidth by the number of sub-carriers;

the bandwidth of initial PUSCH transmission is represented by the number of subcarriers;

Considering that ACK/NACK information or RI information can occupy at most 4 SC-FDMA symbols per subframe, therefore Q'_layerShould be less than

Get it right

Step 430, performing channel coding on the uplink control information in the same way as the LTE;

step 440, repeat the bits after the uplink control information channel coding until the number of the corresponding target code modulation symbols is satisfied.

When the uplink control information is to be transmitted on a certain codeword stream after being encoded, "the corresponding target number of coded modulation symbols" in step 440 is obtained by multiplying the modulation order of the transmission block corresponding to the codeword stream by the target number of coded symbols of the uplink control information. If the uplink control information is to be transmitted on two codeword streams, when the above step 440 is performed before multiplexing the uplink control information to each codeword stream, the "corresponding target number of coded modulation symbols" in step 440 is obtained by multiplying the modulation order of the transport block corresponding to the codeword stream by the target number of coded symbols of the uplink control information.

Several application examples based on the above-described embodiment are given below, each of which selects a transport block in a different manner, and since the processes of channel-coding uplink control information and repeating the channel-coded bits in steps 430 and 440 are the same, descriptions of the following examples are omitted.

Example 1

The application scenarios and related parameters of this example are as follows:

assuming that uplink transmission is based on a normal CP, that is, there are 14 SC-FDMA symbols in the subframe, 2 symbols are used for sending a DMRS, and the number of uplink transmission transport blocks is 2, and after the two transport blocks are subjected to channel coding, rate matching and other operations, corresponding codeword streams are mapped to two layers of transmission. No SRS needs to be sent in uplink transmission, UE has data information to be sent, and meanwhile 2-bit ACK/NACK information and 2-bit RI information need to be sent, so that the ACK/NACK information, the RI information and the uplink data information are multiplexed and transmitted on a PUSCH.

Suppose that the UE obtains the bandwidth allocated by the base station for PUSCH transmission according to the information in the DCI format 0 as 1 Resource Block (RB), and the modulation coding indexes of the two transmission blocks are

UE is based on

And the number of RBs can obtain the corresponding TB sizes of 120 and 224 respectively, and the modulation orders of the TB sizes are respectively

In this way, 24-bit CRCs are added to the two transport blocks, and after code block segmentation, the number of code blocks of each transport block is C⁰＝1，C ¹1, the code block size is respectively

Arranged by

In this example, the UE selects a modulation code index in two transport blocks in step 410Guiding deviceSmaller one transport block (i ═ 0) because

So the first transport block with index 0 is selected. In step 420, the corresponding calculation is as follows:

according to the foregoing analysis, in the above formula, O is 2,

thus, the target code symbol number Q 'of ACK/NACK information transmitted on each transmission layer can be calculated by the above formula'_ACKperlayer8 becauseCorresponding target code modulation symbol number Q_ACKperlayer16; similarly, the target code symbol number Q 'of RI information transmitted on each transmission layer can be obtained'_RIperlayerNumber of target code modulation symbols Q8_RIperlayer＝16。

In this example, in step 410, the UE selects corresponding one of two transport blocks

One transport block larger. The number of code blocks of each transmission block is C⁰＝1，C ¹1, the code block size is respectively

Therefore, the transport block with index 1 is selected, called the second transport block.

The corresponding calculation employed in step 420 is:

according to the above analysis where O is 2,

thus, the target code symbol number Q 'of ACK/NACK information transmitted on each transmission layer can be calculated by the above formula'_ACKperlayer＝5，Q_ACKperlayer10; obtaining the target code symbol number Q 'when the RI information is transmitted on each transmission layer'_RIperlayer＝5，Q_RIperlayer＝10。

Example three

The application scenario and various parameters of this example are the same as those of example one of embodiment one.

In this example, the UE is selected in step 410The larger of the two transport blocks is selected. After being segmented, the code block size of each transmission block is respectively

Has TB0_size＜TB1_sizeWherein, TB0_sizeTB1 for the size of transport block with index 0_sizeIs the size of the transport block with index 1. So the transport block with index 1 is selected. In step 420, the calculation formula and the calculation result are the same as those in the second example of the first embodiment, and are not repeated.

Example four

The application scenario and various parameters of this example are the same as those of example one of embodiment one.

In this example, in step 410, the UE selects one transport block according to the signaling indication, and assuming that the signaling indication indicates the UE to select the first transport block, the calculation formula and the calculation result adopted in step 420 are the same as those in the first example of the first embodiment, and are not repeated.

Example five

In this example, the UE and the base station agree to fixedly select the first transport block in step 410, and the calculation formula and the calculation result adopted in step 420 are the same as those in the first example of the first embodiment and are not repeated.

The present embodiment provides a method for encoding uplink control information based on PUSCH transmission in LTE-a, where two transmission blocks are currently configured, and both the two transmission blocks have uplink data transmission, and two codeword streams are obtained after encoding. The uplink control information is ACK/NACK information or RI information.

As shown in fig. 5, the encoding method of the present embodiment includes:

step 510, a User Equipment (UE) calculates according to the size of the uplink control information, the offset value configured by the high layer, and the parameter information of the first transport block, and the size of the uplink control information, the offset value configured by the high layer, and the parameter information of the second transport block, respectively, to obtain the number of two target coding symbols;

in this step, the formula for the UE to calculate the number of target coding symbols of each transport block is the same as the formula for the UE to calculate the number of target coding symbols of uplink control information when the LTE system has uplink data and control information during PUSCH transmission. The number of target coding symbols obtained by calculation based on the parameter information of the transmission block with the index i is set asThen there are:

this equation can also be simplified, please refer to embodiment one. The meaning of each parameter in the formula is the same as that in the first embodiment, and is not repeated.
