Description

High-order coding processing method, device and system

The present invention relates to the field of mobile communications, and in particular, to a high-order coding processing method, apparatus, and system.

Background technique

In mobile communication systems, due to the time-varying characteristics of wireless fading channels, there is a large amount of uncertainty in the communication process. On the one hand, in order to improve the system throughput, high-order modulation with high transmission rate and less redundant error correction code are used for communication, so that the system throughput is greatly improved when the signal-to-noise ratio of the wireless fading channel is ideal. However, when the channel is in deep fading, communication cannot be guaranteed to be reliable and stable. On the other hand, in order to ensure communication reliability, low-order modulation with low transmission rate and large redundant error correction code are used for communication, that is, in wireless When the channel is in deep fading, the communication is guaranteed to be reliable and stable. However, when the channel signal-to-noise ratio is relatively high, the transmission rate is low, which restricts the improvement of the system throughput, thereby causing waste of resources. In the early development of mobile communication technology, people can only use the transmission power of the transmitter to combat the time-varying characteristics of the wireless fading channel, and use the low-order and large-redundancy modulation and coding methods to ensure the communication of the system during deep channel fading. Quality, there is no way to consider how to increase the throughput of the system. With the advancement of the technology level, there has been a technology that can adaptively adjust its transmission power, modulation coding mode and frame length of data according to the channel state to overcome the time-varying characteristics of the channel to obtain the best communication effect, which is called adaptive. Coded modulation technology is the most typical link adaptation technology.

In the Long Term Evolution (LTE) system, in order to implement the adaptive coding and modulation technology, the uplink needs to transmit control signaling including channel state information (CSI: Channel State Information). The CSI includes a Channel Quality Indication (CQI), a Pre-coding Matrix Indicator (PMI), and a Rank Indicator (RI: Rank Indicator). The CSI reflects the state of the downlink physical channel. The base station uses CSI for downlink scheduling and performs data coding and modulation. The feedback of the CSI can be periodic or non-periodic.

CQI is an indicator used to measure the quality of downlink channels. In the 36-213 protocol, CQI is represented by an integer value of 0 to 15, which represents different CQI levels, and different CQIs correspond to each. Self-modulation coding scheme (MCS: Modulation and Coding Scheme), see Table 1. The CQI level selected by the UE (User Equiment) should be such that the physical downlink shared channel (PDSCH: Physical Downlink Shared Channel M special transport block (TB: Transport Block) corresponding to the CQI is in the corresponding MCS. Not more than 0.1.

Table 1

In Table 1 above, QAM represents Quadrature Amplitude Modulation, and QPSK represents Quadrature Phase Shift Keying, which is a digital modulation method. In LTE, the CQI is represented by 4 bits in addition to the differential CQI. The CQI bit is included in the uplink control information (UCI: Uplink Control Information). The base station performs scheduling according to the CQI reported by the terminal, and determines downlink MCS index and resource allocation information. Specifically, the LTE protocol of Rel-8 defines a Modulation and TBS index table (hereinafter also referred to as MCS Table, MCS table). The table has a total of 32 levels, basically each level corresponds to one MCS index, and each MCS index essentially corresponds to an MCS (or a spectral efficiency, note that the MCS is not limited to the MCS of Table 1). The resource allocation information gives the number of physical resource blocks NPRB that the downlink transmission needs to occupy. The LTE standard also provides a TBS form. According to the table, the transport block size (TBS: Transport block size) can be obtained given the MCS index and NPRB. With these coded modulation parameters (MCS/NPRB/TBS), the base station can perform coded modulation of downlink data for downlink transmission.

After receiving the downlink transmission data, the terminal needs to obtain the MCS index of the downlink transmission and the demodulation decoding of the TBS for the data. The base station transmits downlink control information, including a 5-bit MCS index, and a resource allocation location, by using a physical downlink control channel (PDCCH: Physical Downlink Control Channel) in a specific DCI (Downlink Control Information) format (DCI format). After acquiring the downlink control information, the terminal obtains the TBS according to the TBS table, and is used for demodulation and decoding. The DCI format includes the following types: DCI format O, DCI format 1, DCI format 1A, DCI format 1B, DCI format 1C, DCI format 1D, DCI format 2, DCI format 2A, DCI format 2B, DCI format 2C, DCI format 2D , DCI format 3 and DCI format 3A, etc.

After experiencing several versions of Rel-8/9/10/11, the LTE system has been researching R12 technology. In the Rel-11 standard, the uplink and downlink support up to 64QAM modulation and coding. Along with the development of heterogeneous networks, small cells require higher data transmission rates and higher system spectral efficiency, and require higher order modulation coding, such as 256 QAM. Existing standards cannot meet this need. For example, the conventional table of the LTE standard, that is, the CQI table/MCS table/TBS table supports up to 64 QAM modulation coding mode and spectral efficiency of about 5.5547 bits/s/Hz.

Taking the LTE system as an example, the conventional table (ie, the existing CQI table, the MCS table, the TBS table) cannot support the higher order modulation mode. After the high-order modulation mode is introduced in the communication system, such as 256 QAM and 1024QAM, it is necessary to design an enhanced table (new CQI table) supporting high-order modulation. MCS table, TBS table). There are two design schemes: The enhanced table size of the MCS level including the high-order modulation mode of the first scheme is equal to the regular table size. For example, for the LTE system, the new CQI table and the MCS table are 16 and 32 levels respectively; The enhanced table size including the high-order modulation mode MCS level is larger than the conventional table. For example, for the LTE system, the new CQI table and the MCS table are 32 and 64 levels, respectively. The larger the table, the larger the spectral efficiency range that can be covered, or the higher the spectral efficiency granularity; but the more bits needed to represent the table. In order to briefly describe the advantages and disadvantages of the two schemes, the following LTE system introduces the design of the new CQI table after 256QAM as an example. For scenario 1, the spectral efficiency range covered by the new CQI table and the spectral efficiency granularity (the spectral efficiency granularity corresponds to the accuracy of the channel state feedback) are a pair of contradictions. That is, covering a large spectral efficiency range necessarily leads to a reduction in spectral efficiency granularity; maintaining the existing spectral efficiency granularity necessarily results in an enhanced table that cannot cover the minimum spectral efficiency in the regular table (Table 1) and the highest spectral efficiency of 256 QAM. The range of spectral efficiencies that are limited. However, the solution 1 does not affect the number of CQI bits, and does not cause an increase in the UCI payload (uplink control information load), and does not consider the UCI demodulation performance degradation problem that may be caused by the increase in CQI bits. For scenario two, the new CQI table/MCS table can completely cover the minimum spectral efficiency in the existing table and the frequency efficiency range limited by the highest frequency efficiency of 256 QAM without affecting the spectral efficiency granularity, but increase The number of CQI bits needs to consider the problem of increased UCI payload and degraded UCI demodulation performance. Similarly, similar problems exist with the new MCS table approach.

At present, the conventional table of the communication system cannot support the higher-order modulation mode, and does not solve the problem of the configuration use of the specific high-order modulation enhancement table and the regular table. Therefore, current communication systems cannot support higher order modulation methods. In scenes where channel conditions are better and higher order modulation schemes may be applied, such as Small Cell scenarios, the peak data transmission rate and the efficiency of the system spectrum are limited.
