[0045] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as a limitation to the present application.

[0046] In the NR mode, the amount of uplink transmitted data is large. When moving user data to the physical layer for channel processing, the requirements for the bandwidth and access latency of the bus for data transfer increase significantly. There are two ways to address this problem: One is the conventional method of transferring all the data at once, which requires a large buffer; the other is the small buffer method, which transfers data in units of decoding blocks, the smallest bit-level processing unit, so that only two ping-pong decoding block buffers need to be opened.

[0047] In one embodiment, a channel processing method is proposed. Figure 1 It is a timing schematic diagram of a channel processing method provided by an embodiment of the present application. As Figure 1 shown, the processing process of user data is as follows:

[0048] First, data transfer warm-up is performed. During this period, the channel processing system will perform preparatory work for data transmission to facilitate subsequent data transmission.

[0049] After the warm-up is completed, data transfer is started, that is, user data is transmitted to the buffer. Among them, the buffer space is allocated according to a pre-configured protocol; in this embodiment, the size of the buffer space allocated by the protocol is the same as the amount of data that the maximum transmission block can carry, so all user data can be transferred to the buffer space at once.

[0050] After the transfer is completed, bit-level processing of the user data in the buffer is started.

[0051] After the bit-level processing is completed, symbol-level processing of the data is performed. Since these data need to be sent out through a wireless channel and the data in the channel is transmitted in units of symbols, symbol-level processing can facilitate the transmission of data in the channel.

[0052] Figure 1 The first time slot and the transmission time slot in [figure] contain multiple time periods corresponding to the symbol length (0, 1, 2,..., 13). It can be seen that data is sent starting from the beginning of the first symbol in the transmission time slot. The starting time point of each symbol-level processing is at the beginning of a symbol. After the first 2 symbol-level processings are completed, when the 3rd symbol-level processing starts, the user data that has completed symbol-level processing starts to be sent at the same time. Among them, a time period corresponding to the symbol length is used to transmit the data carried in a single symbol.

[0053] In one embodiment, a channel processing method is proposed. Figure 2 It is a timing schematic diagram of a channel processing method provided by an embodiment of this application. As Figure 2 shown, the processing process of user data is as follows:

[0054] Perform data transfer warm-up. After the warm-up is completed, the user data is transmitted to the cache. The size of the cache space is the amount of data that a single decoding block can carry. Each transmission block contains multiple decoding blocks. Therefore, in this embodiment, the cache space is small and the time used for each data transmission is less. Optionally, the transmission block contains 70 decoding blocks.

[0055] Perform bit-level processing on the user data in the cache space, and then perform symbol-level processing.

[0056] Send out the data that has completed symbol-level processing.

[0057] Among them, the size of the decoding block is related to the code rate. Generally, the initial transmission ratio relationship is relatively stable, and it changes greatly during retransmission.

[0058] In the communication field, each symbol contains multiple decoding blocks. Figure 2 contains multiple time periods corresponding to the symbol length. During the processing, a time period corresponding to one symbol length is used for the channel processing system to process the signal carried in the symbol. Each small time period (0, 1, 2,..., 13) corresponds to the time for processing the decoding blocks contained in the symbol. For example, in time period 0, the data carried by the first decoding block in the current symbol is processed. It is different from the time scale of Figure 1 and is smaller than the time scale of Figure 1 In this embodiment, because the cache space is small, each data transfer process needs to start after the previous bit-level processing is completed. In each symbol, the starting time point of the first data transfer warm-up is at the beginning of the symbol. After the data processing in the first 2 symbols is completed, at the beginning of the 3rd symbol level, the user data that has completed symbol-level processing is sent at the same time.

[0059] In the above solution, Figure 1 In the solution of , because the cache space is large, the user data can be transferred in one go and subsequent processing can be performed. However, because the amount of data transferred at one time is large, it has high requirements for the system hardware, and one-time data transfer will cause a long bus occupancy time and have a negative impact on other modules in the system. Figure 2The scheme in [it] has a relatively small cache space, and the user data can be transported in multiple times, with relatively low requirements for system hardware. However, since the data transfer warm-up needs to be performed again in each data transfer, the time proportion occupied by the data transfer warm-up is relatively high as a whole, and the overall data processing efficiency is relatively low.

[0060] To address this problem, the embodiments of the present application provide a channel processing method. Figure 3 It is a schematic flowchart of a channel processing method provided by the embodiments of the present application. As Figure 3 shown, the method includes the following steps:

[0061] Step 101, set a first cache area according to the size of the transport block, where the transport block is used to transport data;

[0062] In this embodiment, the physical block uplink and downlink data sharing channels transmit data in units of transport blocks (TBs, Transport Blocks). To enable the cache space to store sufficient data to be transmitted and avoid the process of waiting for all the data in the cache space to be processed before the next data transfer, the size of the first cache area is set according to the size of the transport block.

[0063] Optionally, step 101 specifically includes:

[0064] Obtain the maximum data volume that a single transport block can carry;

[0065] Configure the first cache area according to the maximum data volume, where the size of the first cache area is the same as the maximum data volume.

[0066] Step 102, transmit the data to be transmitted to the first cache area according to the symbol carrying capacity;

[0067] In this embodiment, the amount of data transferred each time is not a fixed value, but is determined according to the carrying capacity of the current symbol. Since a transport block contains multiple symbols, the data to be transmitted each time will not fill the space of the first cache area, so the amount of data transferred each time can exactly meet the carrying capacity of the current symbol. At the same time, the data to be transmitted is transferred in multiple times, avoiding the pressure on the system caused by transmitting too much data at one time.

[0068] Optionally, the transmitting the data to be transmitted to the first cache area according to the symbol carrying capacity includes:

[0069] Obtain the amount of transferable data that a single symbol can carry;

[0070] Transmit the data to be transmitted to the first cache area according to the amount of transferable data, where the amount of data transmitted each time is less than or equal to the amount of transferable data.

[0071] Step 103: Process the data to be transmitted corresponding to each symbol in the first buffer area and transmit the data to be transmitted.

[0072] In this embodiment, the data to be transmitted is repeatedly processed through the process of "data transfer warm-up - data transfer - bit-level processing - symbol-level processing". The amount of data to be transmitted in each transmission is based on the carrying capacity of a single symbol. For the data to be transmitted of different symbols, their "data transfer warm-up - data transfer - bit-level processing - symbol-level processing" are independent of each other. That is to say, the bit-level processing and symbol-level processing of the data to be transmitted in the current symbol do not affect the processing process of the data to be transmitted in the next symbol. During the bit-level processing of the data to be transmitted in the current symbol, the data transfer of the data to be transmitted in the next symbol can start and be transferred to the first buffer area. In this way, the coupling between the data transfer process and the data processing process can be eliminated, and the overall channel processing efficiency of the system can be improved.

[0073] Optionally, the step 103 of processing the data to be transmitted in the first buffer area includes:

[0074] After each completion of the transmission of the data to be transmitted, start processing the data to be transmitted of this time.

[0075] During the processing of the data to be transmitted this time, perform the transmission of the next data to be transmitted.

[0076] In one embodiment, a channel processing method is proposed. Figure 4 This is a timing schematic diagram of a channel processing method provided by an embodiment of this application. As Figure 4 shown, the processing process of user data is as follows:

[0077] The first symbol:

[0078] Perform data transfer warm-up. After the warm-up is completed, transfer the data to be transmitted to the first buffer space. The size of the first buffer space is the amount of data that the maximum transmission block can carry. The amount of data transmitted this time is the amount of transfer data that a single symbol can carry.

[0079] Perform bit-level processing on the user data in the first buffer space, and then perform symbol-level processing.

[0080] The second symbol:

[0081] Perform data transfer warm-up. After the warm-up is completed, transfer the data to be transmitted to the first buffer space. The size of the first buffer space is the amount of data that the maximum transmission block can carry. The amount of data transmitted this time is the amount of transfer data that a single symbol can carry.

[0082] Perform bit-level processing on the user data in the first cache space, and then perform symbol-level processing;

[0083] The third symbol:

[0084] Perform data transfer warm-up, and at the same time send out the data that has completed symbol-level processing in the first two symbols. Tx is the abbreviation of Transmit, representing the action of sending data.

[0085] In this embodiment, the processing process of the first symbol and the processing process of the second symbol are independent of each other and do not affect each other, avoiding the situation where the embodiment in Figure 2 requires the processing of the first symbol to be completed and the cache space to be freed before the second symbol can be processed, improving the processing efficiency. And since the amount of data transmitted each time is smaller than that in the embodiment in Figure 1 the data transfer process of the data to be transmitted will not cause too much pressure on the system.

[0086] Optionally, the step 103 processes the data to be transmitted in the first cache area, including:

[0087] Perform bit-level processing on the data to be transmitted, and transmit the data to be transmitted to the second cache area, where the second cache area is the output cache for bit-level processing;

[0088] Perform symbol-level processing on the data to be transmitted in the second cache area.

[0089] In a possible embodiment, the bit-level processing includes: adding CRC to the channel block, code block segmentation, channel coding, rate matching, etc. Among them, the role of rate matching is code rate matching. Considering the number of physical resource blocks, the channel capacity is already determined. In the scenario where the transmission block sizes in the physical layer transmission are different, the role of rate matching is to adapt the transmission capacity of different-sized transmission blocks after coding through repetition or puncturing.

[0090] The rate matching link can be divided into two steps: sub-block interleaving, bit collection and selection.

[0091] In a possible embodiment, the channel-level processing includes precoding, etc.

[0092] To implement the above embodiment, the present application also proposes a channel processing device. Figure 5 It is a schematic structural diagram of a channel processing device provided by an embodiment of the present application. As Figure 5 shown, the device includes:
