Description

Polarization code processing method and device and node

The application is to the application number: 201610451966.6, filing date: the invention is a division application of original application of 'polarization code processing method and device and node' in 2016, 06 and 21.

Technical Field

The present invention relates to the field of communications, and in particular, to a method and apparatus for processing a polarization code, and a node.

Background

In a long term evolution (Long Term Evolution, abbreviated as LTE) system, in order to implement a downlink adaptive code modulation technique, uplink needs to transmit control signaling including channel state information (Channel State Information, abbreviated as CSI). The CSI includes a channel quality indication (Channel quality indication, abbreviated CQI), a precoding matrix indication (Pre-coding Matrix Indicator, abbreviated PMI), and a Rank Indicator (RI). The CSI reflects the downlink physical channel state. And the base station performs downlink scheduling by using the CSI and performs coded modulation of data.

CQI is an index for measuring the quality of a downlink channel. In the 36-213 protocol, CQI is represented by an integer value index of 0-15, and represents different CQI levels, respectively, where different CQI corresponds to a respective modulation coding scheme (Modulation and Coding Scheme, abbreviated MCS). The CQI level selected by the User Equipment (UE) should be such that the Block error rate of the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) Transport Block (TB) in the MCS corresponding to the CQI is not more than 0.1, and the selected CQI is the maximum CQI index satisfying the condition.

The base station performs scheduling in combination with CSI reported by the terminal, and determines an index of a downlink modulation coding scheme (Modulation and Coding Scheme, abbreviated as MCS) and resource allocation information. Specifically, the LTE protocol of Rel-8 defines a modulation and transport block size table (Modulation and TBS index table for PDSCH, hereinafter also referred to as a downlink MCS table) for the physical downlink shared channel (Physical Downlink Shared Channel, PDSCH for short). The table has a total of 32 levels, with essentially one MCS index for each level, and essentially one MCS for each MCS index. The resource allocation information indicates the number of physical resource blocks (Number of Physical Resource Block, NPRB for short) that the downlink transmission needs to occupy. The LTE standard also provides a TBS table. From the table, a transport block size (Transport block size, abbreviated TBS) is obtained given the MCS index and NPRB. With these coding modulation parameters (MCS/NPRB/TBS), the base station can perform coding modulation of downlink data and perform downlink transmission.

After receiving the downlink data, the terminal needs to acquire the MCS index and the resource allocation information for downlink data processing. And the base station transmits the MCS index and the resource allocation information through downlink control information (Downlink Control Information, DCI for short). The base station uses a specific radio network temporary identifier (Radio Network Temporary Identity, abbreviated RNTI) to scramble Cyclic Redundancy Check (CRC) bits corresponding to the downlink control information. And transmits the downlink control information in a specific downlink control information format (DCI format) through a physical downlink control channel (Physical Downlink Control Channel, abbreviated PDCCH). The terminal performs blind search in a public search space (Common Search Space, abbreviated as CSS) and a user equipment specific search space (UE-specific Search Space, abbreviated as USS) to acquire downlink control information. And the terminal obtains TBS according to the TBS table after obtaining the downlink control information and uses the TBS for demodulation and decoding.

There are various kinds of radio network temporary identities, including Semi-persistent scheduling (Semi-persistent Scheduling, SPS for short), cell radio network temporary identity (Semi-persistent Scheduling Cell RNTI, SPS C-RNTI for short), cell RNTI (C-RNTI for short), and the like. DCI formats related to PDSCH include a variety of: DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format 1D, DCI format 2A, DCI format 2B, DCI format 2C, DCI format 2D, etc.

And the adaptive coding modulation of the uplink has a similar process. And the base station utilizes the pilot frequency sent by the terminal to perform channel estimation and scheduling, and determines the index of the uplink code modulation coding scheme and the resource allocation information. The base station transmits the MCS index and the resource allocation information through the DCI and is used for modulation coding processing of the terminal. After receiving the data of the terminal, the base station performs demodulation and decoding according to the relevant coding and modulation parameters (MCS/NPRB/TBS).

In Rel-13 LTE standard, turbo codes and convolutional codes are mainly used for physical shared channels, and more new coding schemes, such as Polar codes (Polar codes), are introduced in the research of fifth generation wireless communication technology. The polarization code is a coding mode which utilizes channel polarization and is proved by theory to approach the capacity of a symmetrical binary discrete memory-less channel (B-DMC). In the construction of the polarization code, it is necessary to select a better polarization channel for the information bits using the noise-related information and the channel condition-related information. In a standard polar-code encoder, the encoder output bit sequence length N is a power of 2. The choice of N also depends on the number of bits that the time-frequency resource can carry and the modulation order, among other parameters.

The construction and coding of the polarization code requires relevant coding parameters and channel related information. However, how to solve the problem of encoding or decoding the polarization code has not been proposed at present.

The bit position information may be information bit position information or freeze bit position information. The length N bit sequence entering the polar encoder comprises length K information bits and N-K known bits, also called freeze bits. The output of the polar encoder is a sequence of coded bits of length N. For a given polarization code generation matrix, the order of the positions of the information bits or the freeze bits needs to be properly arranged, that is, a good channel is selected for the information bits, so as to obtain better code performance. Regarding the polarization code coding principle, reference may be made to the paper: erdal Arikan, channel Polarization: A Method for Constructing Capacity-Achieving Codes for Symmetric Binary-Input Memoryless Channels, IEEE Transactions on Information Theory, vol.55, no.7, july 2009.

The invention is further explained below in connection with preferred embodiments for a better understanding of the invention.

Preferred embodiment 1

In the preferred embodiment, the base station encodes the data using a polar code and transmits the data to the terminal. The terminal receives downlink control signaling DCI transmitted by the base station, and reads a coded modulation scheme index IMCS (corresponding to the MCS index in the above embodiment) and resource allocation information from the DCI. And acquiring a modulation order M and a transmission block size index ITBS according to the IMCS lookup MCS table.

In the preferred embodiment, the terminal obtains first power indication information according to DCI signaling sent by the base station, where the first power indication information indicates a first noise variance. The first power indication information is IMCS, and is implicit power indication information. The terminal can also obtain the equivalent noise variance a by looking up the MCS table according to the IMCS. An example of the MCS table is shown in table 1. In table 1, each IMCS class corresponds to a combination of coding schemes corresponding to an equivalent signal-to-noise ratio SNR interval or also to an equivalent noise variance interval a. Within the equivalent noise variance interval a, the coded modulation scheme has a maximum spectral efficiency such that the BLER is not greater than 0.1. In table 1, each IMCS corresponds to one noise variance a. The noise variance a is used for code construction in polarization code encoding.

TABLE 1

In the preferred implementation, the terminal obtains the physical resource block size NPRB allocated by the base station according to the resource allocation information. And the terminal determines the length N of the bit sequence coded and output by the polarization code coder according to the NPRB and the modulation order.

Specifically, let N0 be the number of bits carried on the time-frequency resource, and n0=nprb reperbb×m. Wherein, reperbb is the number of resource units RE (Resource Element) of one physical resource block PRB. N is a power of 2 and the possible value of N is { N1, N2}. N1 is a power of the smallest 2 greater than N0, and N2 is a power of the largest 2 less than N0. If N0 is ≡ sqrt (N1 x N2), then n=n1, otherwise n=n2. Where sqrt denotes a root number. If n=n1, then the polar encoder output will be punctured, i.e., part of the bits are discarded from being transmitted; if n=n2, the bits output by the polar encoder will be transmitted repeatedly. Thereby obtaining a bit sequence matching the time-frequency resource. Two possibilities are provided for the value of N, and one of the possibilities is selected according to the conditions, so that the polarization code block error rate performance is improved, and the coding and decoding complexity is reduced. For example, when N0 is close to N1, the punching performance of the code length N1 is better by adopting a punching mode; when N0 is close to N2, N2 is selected as the code length and is repeatedly transmitted, the complexity is lower, and the performance is better.

In the preferred embodiment, N0 is ≡sqrt (N1×n2), so n=n1. In this implementation, the terminal also searches the transport block size table according to the ITBS and NPRB to obtain the transport block size TBS.

Further, the terminal determines information bit position information according to the modulation order M and the noise variance a, and the code length N.

Preferred embodiment 2

The present preferred embodiment is different from the preferred embodiment 1 in that the terminal obtains the first power indication information according to DCI signaling transmitted by the base station. The first power indication information is not IMCS but explicit power indication information Iad. The first power indication information indicates a first noise variance.

Iad is represented by m1=5 bits for a total of 32 ranks. The value of 5 bits is 0-31. Each value corresponds to a first noise variance value a and a noise variance interval a. An example of the correspondence between Iad values and a/A is shown in Table 2. The terminal looks up table 2 according to Iad to obtain the corresponding a. The noise variance a is used for code construction in the case of polarization code coding and is also a parameter that is required to be known by the terminal for decoding.

On the base station side, when the base station performs the polarization code encoding, a is obtained from the section a where the actual noise variance is located and table 2, and the encoding is performed according to a.

In table 2, when a is (1.4380, + -infinity) and [0,0.0011), the value of a is 1.7982 and 0.0011 respectively. This expands the noise variance or SNR interval to which the polar code applies, so that the polar code can be used for encoding and decoding also in a larger SNR range.

In this embodiment, the first power indication information may further indicate one of the following: signal power value, signal power offset value (power offset), noise power value, noise power offset value, equivalent SINR. Correspondingly, each value of the noise variance indication information Iad in table 2 corresponds to one power value/power offset value/SINR, and one power/power offset value/SINR interval. The corresponding power value/power offset value/SINR may be from minus infinity to plus infinity according to different definitions of power value/power offset value/SINR. The power value or the offset value, and SINR may be used to obtain information bits or position information of frozen bits when encoding and decoding the polarization code.

TABLE 2

Example 3

In the preferred embodiment, the base station uses a polar code for the encoding process. Before performing the polarization code encoding, the base station needs to obtain downlink equivalent second power indication information, and the power information can be used for code construction during the polarization code encoding.

The terminal transmits second power indication information, which is explicit power indication information Iad, to the base station. For indicating a second noise variance. The Iad is represented by m1=5 bits for a total of 32 ranks. The value of 5 bits is 0-31. Each value corresponds to a noise variance value a and a noise variance interval a. An example of the correspondence between Iad values and a/a is shown in table 2.

The terminal performs channel estimation to obtain a second noise variance of the actual link, obtains a corresponding interval a according to the obtained noise variance, and obtains Iad according to table 2.

The base station can obtain the corresponding a and the second noise variance a according to Iad lookup table 2.

The base station obtains the noise variance through the second power indication information sent by the terminal, which is helpful for better selecting the good channel corresponding to the information bit of the polarization code and improving the performance of the code. In fact, the base station may also use the second power indication information transmitted by the terminal as the first power indication information.

In this embodiment, the second power indication information may further indicate one of the following: signal power value, signal power offset value (power offset), noise power value, noise power offset value, equivalent SINR. Correspondingly, each value of the noise variance indication information Iad in table 2 corresponds to one power value/power offset value/SINR, and one power/power offset value/SINR interval. The power value or the offset value, and SINR may be used to obtain information bits or position information of frozen bits when encoding and decoding the polarization code.

Preferred embodiment 4

The present preferred embodiment is different from the preferred embodiment 4 in that the second power indication information obtained by the base station is implicit power indication information indicating a second noise variance and is a channel quality indication CQI. An example of the table of correspondence between CQI and second noise variance a is shown in table 3. The base station can obtain the corresponding a according to the CQI lookup table 3.

TABLE 3 Table 3

In this embodiment, the CQI may further indicate one of the following: signal power value, signal power offset value (power offset), noise power value, noise power offset value, equivalent SINR. Correspondingly, each value of the noise variance indication information CQI in table 3 corresponds to one power value/power offset value/SINR, and one power/power offset value/SINR interval. The power value or the offset value, and SINR may be used to obtain information bits or position information of frozen bits when encoding and decoding the polarization code.

Example 5

The present preferred embodiment is different from the preferred embodiment 5 in that when the terminal determines the bit sequence length N of the encoded output of the polarization code encoder according to NPRB and modulation order, if n0+ (n1+n2)/2, n=n1, otherwise n=n2. Using the arithmetic average of N1 and N2 as a discrimination condition may make N more prone to be selected as N2 than the geometric average of N1 and N2, thereby contributing to a reduction in coding complexity.

Example 6

The present preferred embodiment differs from preferred embodiment 1 in the determination of N0. In the preferred embodiment, the coded bits of the polarization code are modulated by M-QAM modulation, where M is an even number. And there are a total of M/2 polar code encoders, the output of each encoder corresponding to two of the M bits of the M-QAM constellation point. Thus N0 satisfies n0=nprb reperbb M/(M/2) =2 NPRB reperbb. Wherein, reperbb is the number of resource units RE (Resource Element) of one physical resource block PRB.

Example 7

In the preferred embodiment, the terminal encodes with a polar code and transmits the data to the base station.

In the preferred embodiment, the terminal receives DCI transmitted from the base station. The coded modulation scheme index IMCS and the resource allocation information are read from the DCI. And acquiring a modulation order M and a transmission block size index ITBS according to the IMCS lookup MCS table.

In the preferred embodiment, the terminal obtains the first power indication information according to the DCI signaling sent by the base station. The first power indication information is IMCS, and is implicit power indication information, indicating a first noise variance. The terminal can also obtain the equivalent noise variance a by looking up the MCS table according to the IMCS. An example of the MCS table is shown in table 1. In table 1, each IMCS class corresponds to a combination of coding schemes corresponding to an equivalent signal-to-noise ratio SNR interval and also to an equivalent noise variance interval a. Within the equivalent noise variance interval a, the coded modulation scheme has a maximum spectral efficiency such that the BLER is not greater than 0.1. In table 1, each IMCS corresponds to one noise variance a. The noise variance a is used for code construction in polarization code encoding.

Specifically, let N0 be the number of bits carried on the time-frequency resource, and n0=nprb reperbb×m. Wherein, reperbb is the number of resource units RE (Resource Element) of one physical resource block PRB. N is a power of 2 and the possible value of N is { N1, N2}. N1 is a power of a minimum 2 greater than N0, N1, N2 is a power of a maximum 2 less than N0. If N0 is ≡ sqrt (N1 x N2), then n=n1, otherwise n=n2. Where sqrt denotes a root number. If n=n1, then the polar encoder output will be punctured, i.e., part of the bits are discarded from being transmitted; if n=n2, the bits output by the polar encoder will be transmitted repeatedly. Thereby obtaining a bit sequence matching the time-frequency resource. Two possibilities are provided for the value of N, and one of the possibilities is selected according to the conditions, so that the polarization code block error rate performance is improved, and the coding and decoding complexity is reduced. For example, when N0 is close to N1, the punching performance of the code length N1 is better by adopting a punching mode; when N0 approaches N2, N2 is selected as the code length and repeated transmission is performed, the complexity is lower, and the performance is not greatly reduced.

Further, the terminal encodes the polarization code based on N, information bit position information (or generator matrix), noise variance a and modulation order M.

In the preferred implementation, the IMCS indicates the noise variance, so that the correct implementation of the polarization code coding can be ensured. Nor add new signaling overhead.

Of course, table 4 may be only a part of the table.
