Description

Technical Field

[0001] This application relates to the field of channel coding, and more specifically, to a communication method and related communication apparatus. Background Technology

[0002] Uplink control information (UCI) can include various types of information, such as hybrid automatic repeat request acknowledgement (HARQ-ACK), scheduling request (SR), and channel state information (CSI). When UCI is transmitted along with uplink data, both UCI and uplink data need to be multiplexed in both the time and frequency domains. UCI and uplink data can be multiplexed using different mapping rules, different mapping orders, different time-domain offsets, or different frequency-domain offsets, which undoubtedly increases the processing complexity at both the transmitting and receiving ends. Summary of the Invention

[0003] This application provides a communication method and a communication device that can reduce the processing complexity of the sending and receiving ends.

[0004] Firstly, a communication method is provided, which can be executed by a transmitting device. Unless otherwise specified, "transmitting device" in this application can refer to a transmitting equipment (e.g., a network device, terminal device, encoding device, etc.), a component within that transmitting equipment (e.g., a processor, chip, or chip system, etc.), or a logic module or software capable of implementing all or part of the functions of the transmitting device. The components of the transmitting device can be within the transmitting device or can be independent of it. The method can include: the transmitting device acquiring control information and data to be transmitted; the transmitting device modulating the control information and data based on a first modulation scheme to obtain a modulation symbol stream, the modulation symbol stream including multiple modulation symbols, each modulation symbol carrying control information and data; and the transmitting device outputting the modulation symbol stream.

[0005] Based on the above method, control information and data can be modulated using a unified modulation method to achieve the multiplexing of control information and data, thereby simplifying the multiplexing process of control information and data and reducing the processing complexity of the sending and receiving ends.

[0006] In conjunction with the first aspect, in some implementations of the first aspect, the energy level of the bits used to carry control information in each of the plurality of modulation symbols is greater than or equal to the energy level of the bits used to carry data.

[0007] Based on the above method, higher transmission reliability of control information compared to data can be achieved by carrying control information on bits of a higher energy level, which simplifies the processing flow for achieving higher transmission reliability of control information compared to data.

[0020] Based on the above method, different types of control information can be further distinguished and carried on bits of different energy levels. The transmission reliability of different types of control information can be flexibly adjusted, and multiple types of control information can be transmitted simultaneously.

[0059] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0060] Before introducing the scheme of this application, the following points should be noted.

[0061] First, in this application, the indication includes explicit indication (also known as direct indication) and implicit indication (also known as indirect indication). Explicit indication information A means including information A; implicit indication information A means indicating information A through the correspondence between information A and information B, and direct indication information B. The correspondence between information A and information B can be predefined, pre-stored, pre-burned, or pre-configured; or it can refer to indicating information A through information B and preset rules.

[0062] Second, in this application, "at least one" means one or more, and "more than one" means two or more. The expression " / " is used to indicate that the objects before and after are in an "or" relationship; for example, A / B can mean: A or B. The expression "and / or" is used to indicate that the objects before and after are in a relationship of either "and" or "or", for example, A and / or B can mean: A exists alone, A and B exist simultaneously, or B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the objects before and after are in an "or" relationship, but it does not exclude the possibility that the objects before and after are in a relationship of "and". The specific meaning can be understood in conjunction with the context. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a and b and c. Where a, b, and c can be single or multiple.

[0063] Third, the use of prefixes such as "first" and "second" in this application is solely for the purpose of distinguishing different things belonging to the same name category, and does not constrain the order, size, or quantity of things. For example, "first code block" and "second code block" are simply different code blocks, and there is no temporal sequence, size, or priority relationship between them; similarly, "first control information layer" and "second control information layer" are simply different control information layers, and there is no temporal sequence, size, or priority relationship between them. It should be understood that such described objects can be interchanged where appropriate, so as to describe solutions other than those in the embodiments of this application.

[0064] Fourth, in this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which can include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which can include direct reception from YY via the air interface or indirect reception from YY by other units or modules via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, sending and receiving can occur between devices, such as between a terminal device and a computing node, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0065] Fifth, in the embodiments of this application, "when," "if," and "if" all refer to the device making corresponding processing under certain objective circumstances, and are not limited to a time, nor do they require the device to make a judgment action when it is implemented, nor do they mean that there are other limitations.

[0066] Sixth, in this application, the words "example," "exemplarily," "for example," or "such as" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "example," "exemplarily," "for example," or "such as" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "example," "exemplarily," "for example," or "such as" is intended to present the relevant concepts in a specific manner.

The core network device in core network 200 and network device 101 in RAN 100 can be different physical devices, or they can be the same physical device integrating core network logical functions and radio access network logical functions.

Optionally, the UE can be used as a base station. For example, the UE can act as a scheduling entity, providing sidelink signaling between UEs in V2X or SL, etc.

[0072] In this embodiment, the device used to implement the functions of the terminal device can be the terminal device itself, or any device capable of supporting the terminal device in implementing the corresponding functions, such as a chip, processor, circuit, hardware, and / or software combination. This device is located on the terminal side and can be configured within or used in conjunction with the terminal device. The chip system can consist of chips or include chips and other discrete components. In this embodiment, the terminal device is used as an example to illustrate the device for implementing the corresponding functions of the terminal device.

[0073] The network device in this application embodiment may include a device for communicating with a terminal device. This network device may include an access network device or a radio access network device; for example, the network device may be a base station. In this application embodiment, the access network device may refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names such as: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), master station, auxiliary station, motor slide retainer (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), radio unit (RU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or a combination thereof.

A base station can also be a mobile switching center, a device performing base station functions in D2D, V2X, and M2M communications, a network device (e.g., a base station) in a future communication network, or a device performing network device functions. A base station can support networks using the same or different access technologies. Optionally, a RAN node can also be a server, wearable device, vehicle, or in-vehicle equipment. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). The embodiments of this application do not limit the specific technology or device form used in the network equipment.

[0074] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0075] In some deployments, the network device in this application embodiment may be a device including a CU, or a DU, or a device including both CU and DU, or a control plane CU node (central unit-control plane (CU-CP)) and a user plane CU node (central unit-user plane (CU-UP)) and a DU node. For example, the network device may include gNB-CU-CP, gNB-CU-UP, and gNB-DU.

[0076] In some deployments, multiple RAN nodes collaborate to assist terminals in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CU-CPs, CU-UPs, or RUs. CUs and DUs can be configured separately or included in the same network element, such as a BBU. RUs can be included in radio frequency equipment or radio frequency units, such as RRUs, AAUs, or RRHs.

[0077] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open radio access network (ORAN / O-RAN) system, CU can also be called an open CU (open CU, O-CU), and DU can also be called an open DU (open DU, O-DU). CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0078] In this embodiment, the device used to implement the functions of the network device can be the network device itself; it can also be a device capable of supporting the network device in implementing the corresponding functions, such as a chip, processor, circuit, hardware, and / or software combination. This device is located on the network side and can be configured within or used in conjunction with the network device. In this embodiment, only the network device is used as an example to illustrate the implementation of the corresponding functions of the network device.

[0079] Figure 2This is a schematic diagram of the signal processing process of the physical layer applicable to embodiments of this application. The signal processing of the physical layer can be divided into downlink processing and uplink processing.

[0080] Downlink processing is the process of physically processing information data from higher layers before transmitting it. For example, downlink processing includes: performing channel coding (or simply coding) on ​​the layer 2 (L2) information data, modulation, layer mapping, precoding, framing, inverse fast Fourier transform (IFFT), and frequency conversion via radio frequency (RF) or intermediate radio frequency (IRF) into an air interface signal to be transmitted.

[0081] More specifically, the data transmitter can divide the data from Layer 2 into multiple TBs based on the system's supported transport block (TBS) size (TBS), and add a cyclic redundancy check (CRC) code to each TB. If the size of the TB after adding the CRC code exceeds the maximum code block length, the TB can be segmented to obtain multiple code blocks (CBs). Each segmented CB can be further coded with a CRC code to obtain the input to be encoded corresponding to each CB. This input to be encoded is a sequence of bits to be encoded, specifically including the information bits and check bits (i.e., the CRC code) in its corresponding CB. The transmitter can perform channel coding on this input to be encoded, such as low-density parity check (LDPC) coding, polar coding, etc., to obtain the corresponding coded code blocks. Rate matching is performed on the coded code blocks, and the rate-matched coded code blocks are concatenated to form codewords (CWs). The transmitter can scramble the codewords to generate scrambled bits. The scrambled bits are modulated to obtain modulation symbols. After being mapped by resource elements (REs), the modulation symbols are mapped onto multiple REs, thus obtaining the value carried on each RE. Based on the values ​​carried on these REs, the transmitter can generate a baseband signal. The baseband signal can then be processed by RF or IRF and transmitted by the antenna.

[0082] Uplink processing is the process of physical layer processing of signals received through the air interface. For example, uplink processing includes: performing IRF processing on the received signal to obtain the baseband signal, and then completing physical layer signal processing through FFT, deframing, demodulation, and decoding, and then handing the obtained information data to layer 2.

[0083] More specifically, the signal receiver performs RF or IRF processing on the signal received from the antenna to obtain the baseband signal. Subsequently, the receiver's physical layer can sequentially perform RE mapping, demodulation, descrambling, rate matching de-matching, and channel decoding on the signal to obtain the bit sequence before encoding, which may specifically include information bits and parity bits.

[0084] Optionally, after completing RE mapping and before demodulation, the receiver can perform channel equalization. Channel equalization is based on the channel estimated by the channel, and the influence of the channel is removed by using an equalization algorithm, thereby ensuring correct signal demodulation.

[0085] Optionally, after modulation but before RE mapping, the transmitting end can perform layer mapping and precoding. For example, the transmitting end can map the modulation symbols to multiple layers, and the layer-mapped modulation symbols are then precoded to obtain a precoded signal. The precoded signal is then mapped to multiple REs via RE mapping. Correspondingly, after performing de-layer mapping, the receiving end performs channel equalization and then demodulation; or, the receiving end can perform de-layer mapping and then demodulation after completing channel equalization; or it can perform de-layer mapping and then channel equalization after completing deframe.

[0086] because Figure 2 The specific implementation methods for each step can be achieved using existing technologies or future solutions; see the Third Generation Partnership Program (3). rd The relevant sections of the Generation Partnership Project (3GPP) technical specification (TS) 38.211 are not detailed here.

[0087] The apparatus used to implement the above physical layer processing can be a communication device, such as a network device or a terminal device, or a mobile communication chip, such as a baseband chip; this application does not limit this.

[0088] Uplink control information (UCI) can include various types of information such as hybrid automatic repeat request acknowledgement (HARQ-ACK), scheduling request (SR), and channel state information (CSI). Different types of UCI can be transmitted together with uplink data, requiring multiplexing of different types of UCI and uplink data during RE mapping. UCI and uplink data can be multiplexed using different mapping rules, different mapping orders, different time-domain offsets, or different frequency-domain offsets, which undoubtedly increases the processing complexity at both the transmitting and receiving ends. Therefore, this application provides a communication method that can reduce the processing complexity at both the transmitting and receiving ends.

[0089] The communication method provided in this application is described in detail below.

[0090] Figure 3 This is a schematic flowchart of the communication method 300 provided in this application. Steps S310 to S314 in method 300 can be performed by a transmitting device (or an information transmitting device). Optionally, method 300 further includes steps S316 to S320, which can be performed by a receiving device (or an information receiving device).

[0091] S310, the transmitting device acquires the control information and data to be transmitted.

[0092] For example, the control information and data mentioned above can be uplink control information and uplink data, or downlink control information and downlink data.

[0093] For example, control information applicable to embodiments of this application may be encoded or not; data applicable to embodiments of this application may be encoded or partially encoded.

[0094] S312, the transmitting device modulates the control information and the data based on the first modulation method to obtain a modulation symbol stream, which includes multiple modulation symbols.

[0095] Optionally, an encoding process may be included before S312 above.

[0096] For example, the encoding and modulation process can include the following three types:

[0097] Method 1: The transmitting device encodes the first code block to obtain a first codeword sequence; the transmitting device divides the first codeword sequence into layers to obtain at least one control information layer and at least one data layer; the transmitting device modulates the at least one control information layer and the at least one data layer based on a first modulation scheme.

[0098] The first code block mentioned above includes control information and data.

[0099] Figure 4 This is a schematic diagram of an example encoding and modulation process provided in an embodiment of this application. Figure 4 The encoding and modulation process shown may include the following steps:

[0100] (1) Combine the control information and data to be transmitted into a bit sequence.

[0101] For example, the control information to be transmitted can be layer 2 (L2) information, such as information carried by the medium access control element (MAC CE); or, the control information to be transmitted can also be layer 1 (L1) information.

[0102] For example, the control information and data to be transmitted can be concatenated into a bit sequence in sequence, or the control information and data to be transmitted can be combined into a bit sequence by pattern interleaving, row-column interleaving, or equal-interval interleaving.

[0103] (2) Divide the combined bit sequence into multiple CBs.

[0104] For example, if the control information and data to be transmitted are concatenated into a bit sequence in sequence, the multiple CBs obtained by segmentation may include three types of CBs: CBs that only include control information, CBs that include both control information and data, and CBs that only include data; if the control information and data to be transmitted can also be combined into a bit sequence by pattern interleaving, row-column interleaving, or equal-interval interleaving, each CB in the multiple CBs obtained by segmentation is a CB that includes both control information and data.

[0105] The following description uses the example of a CB (Control Controller) that includes both control information and data.

[0106] (3) Encode each of the multiple CBs to obtain multiple codeword sequences.

[0107] For example, the first code block mentioned above can be any one of the multiple code blocks. That is, the first code block among the multiple code blocks is encoded to obtain the first codeword sequence among multiple codeword sequences. For the sake of brevity, the following description uses the first codeword sequence among multiple codeword sequences as an example. The processing of other codeword sequences among multiple codeword sequences can refer to the processing of the first codeword sequence below.

[0108] For example, the encoding method can be a commonly used channel coding method such as LDPC encoding or Polar encoding, and this application does not limit it.

[0109] (4) Rate matching is performed on the first codeword sequence mentioned above.

[0110] (5) The first codeword sequence after rate matching is layered to obtain at least one control information layer and at least one data layer.

[0111] For example, each control information layer in at least one control information layer corresponds to a bit sequence, and each control information layer in at least one control information layer includes control information.

[0112] For example, each data layer in at least one data layer corresponds to a bit sequence, and each data layer in at least one data layer includes data.

[0113] (6) Modulate at least one control information layer and at least one data layer based on the first modulation method.

[0114] For example, the first modulation method mentioned above includes phase shift keying (PSK), amplitude shift keying (ASK), quadrature amplitude modulation (QAM), etc., such as binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8ASK, 16QAM, 64QAM, 256QAM, 1024QAM, 4096QAM, etc.

[0115] For example, the first modulation scheme described above is 8ASK, where each modulation symbol includes 3 bits. The number of control information layers can be 2 or 1, and the number of data layers can be 1. For example, if the number of control information layers is 2 and the number of data layers is 1, the two control information layers are denoted as Control Information Layer 1 and Control Information Layer 2, and the one data layer is denoted as Data Layer 1. Control Information Layer 1 can be carried on the first bit of each modulation symbol, Control Information Layer 2 can be carried on the second bit of each modulation symbol, and Data Layer 1 can be carried on the third bit of each modulation symbol. As another example, if the number of control information layers is 1 and the number of data layers is 1, the one control information layer is denoted as Control Information Layer 1, and the one data layer is denoted as Data Layer 1. Control Information Layer 1 can be carried on the first and second bits of each modulation symbol, and Data Layer 1 can be carried on the third bit of each modulation symbol.

[0116] For example, the first modulation scheme mentioned above is 16QAM, where each modulation symbol includes 4 bits. The number of control information layers can be 2 or 1, and the number of data layers can be 2 or 1. For example, if the number of control information layers and data layers is 2, the two control information layers are denoted as Control Information Layer 1 and Control Information Layer 2, and the two data layers are denoted as Data Layer 1 and Data Layer 2. Control Information Layer 1 can be carried on the first bit of each modulation symbol, Control Information Layer 2 can be carried on the second bit of each modulation symbol, Data Layer 1 can be carried on the third bit of each modulation symbol, and Data Layer 2 can be carried on the fourth bit of each modulation symbol. For another example, if the number of control information layers and data layers is 1, the one control information layer is denoted as Control Information Layer 1, and the one data layer is denoted as Data Layer 1. Control Information Layer 1 can be carried on the first and second bits of each modulation symbol, and Data Layer 1 can be carried on the third and fourth bits of each modulation symbol.

[0117] For example, the first modulation scheme mentioned above is 64QAM, and each modulation symbol includes 6 bits. The number of control information layers can be 2 or 1, and the number of data layers can be 4, 3, 2, or 1. For example, if the number of control information layers is 2 and the number of data layers is 4, the two control information layers are denoted as control information layer 1 and control information layer 2, and the four data layers are denoted as data layer 1, data layer 2, data layer 3, and data layer 4. Control information layer 1 can be carried on the first bit of each modulation symbol, control information layer 2 can be carried on the second bit of each modulation symbol, data layer 1 can be carried on the third bit of each modulation symbol, data layer 2 can be carried on the fourth bit of each modulation symbol, data layer 3 can be carried on the fifth bit of each modulation symbol, and data layer 4 can be carried on the sixth bit of each modulation symbol. For example, if the number of layers of at least one control information layer is 1 and the number of layers of at least one data layer is 2, the one control information layer is denoted as control information layer 1, and the two data layers are denoted as data layer 1 and data layer 2. Control information layer 1 can be carried on the first and second bits of each modulation symbol, data layer 1 can be carried on the third and fourth bits of each modulation symbol, and data layer 2 can be carried on the fifth and sixth bits of each modulation symbol.

[0118] Method 2: The transmitting device encodes at least one second code block to obtain at least one control information layer; the transmitting device encodes at least one third code block to obtain at least one data layer; the transmitting device modulates the at least one control information layer and the at least one data layer based on the first modulation scheme.

[0119] The second code block includes control information, and the third code block includes data.

[0120] Figure 5 This is another example of an encoding and modulation process diagram provided in an embodiment of this application. Figure 5 The encoding and modulation process shown may include the following steps:

[0121] (1) Divide the data to be transmitted into at least one third code block.

[0122] Optionally, the control information to be transmitted can also be divided into at least one second code block.

[0123] For example, the method of dividing the control information to be transmitted into at least one second code block can be similar to the method of dividing the data to be transmitted into at least one third code block. For example, the maximum code block length of the control information is... It can be based on the number of bits of the control information to be transmitted and Determine the number of code blocks for at least one second code block.

[0124] For example, the maximum code block length of the control information is It can be specified by the protocol, the default, or predefined.

[0125] Alternatively, if the number of bits in the control information to be transmitted is small, and the size of the number of bits in the control information to be transmitted may not exceed the maximum code block length, then there is no need to segment the control information to be transmitted. Or, if the control information does not support being segmented into multiple code blocks, then there is also no need to segment the control information to be transmitted.

[0126] (2) Encode at least one second code block; encode at least one third code block.

[0127] For example, the encoding method can be a commonly used channel coding method such as LDPC encoding or Polar encoding, and this application does not limit it.

[0128] For example, at least one second code block is encoded to obtain at least one second codeword sequence; at least one third code block is encoded to obtain at least one third codeword sequence.

[0129] (3) Rate matching is performed on at least one second codeword sequence; rate matching is performed on at least one third codeword sequence.

[0130] For example, at least one second codeword sequence after rate matching can be used as at least one control information layer, and at least one third codeword sequence after rate matching can be used as at least one data layer.

[0131] (4) Modulate at least one control information layer and at least one data layer based on the first modulation method.

[0132] For example, the process of modulating the at least one control information layer and the at least one data layer based on the first modulation method can refer to step (6) of the first method, which will not be repeated here.

[0133] Method 3: The transmitting device obtains at least one control information layer based on the control information to be transmitted; the transmitting device encodes at least one second code block to obtain at least one data layer; the transmitting device modulates the at least one control information layer and the at least one data layer based on a first modulation method.

[0134] The difference between Method 3 and Method 2 is that the control information to be transmitted in Method 3 does not need to be encoded, while the control information to be transmitted in Method 2 needs to be encoded.

[0135] The processes described in methods one through three above all involve encoding first, then layering to obtain at least one control information layer and at least one data layer. Alternatively, it can be done by first layering to obtain at least one control information layer and at least one data layer, and then encoding each layer independently. In this case, a separate code rate (CR) needs to be set for each layer. In this embodiment, the code rate for each layer can be looked up in the modulation and coding scheme (MCS) table shown in Table 1.

[0136] Table 1

[0137]

[0138] Each MCS index shown in Table 1 corresponds to a modulation scheme. For example, the first modulation scheme mentioned above can correspond to any MCS index value among 0, 1, ..., 28. Each MCS index corresponds to a set of parameter configurations, such as modulation order, coding rate, frequency efficiency, etc.

[0139] The first modulation scheme described above corresponds to the coding code rate of each control information layer in at least one control information layer and / or the first modulation scheme described above corresponds to the coding code rate of each data layer in at least one data layer. The coding code rate of one layer (L1) of at least one control information layer can be queried through L1 CR shown in column 2 of Table 1; the coding code rate of another layer (L2) of at least one control information layer can be queried through L2 CR shown in column 3 of Table 1; the coding code rate of the first layer (L1) of at least one data layer can be queried through L1 CR shown in column 4 of Table 1, ..., the coding code rate of the mth layer (Lm) of at least one data layer can be queried through Lm CR shown in column 6 of Table 1.

[0140] It should be understood that Table 1 is an example illustrative example with at least 2 control information layers and at least m data layers. This application does not limit the number of at least 2 control information layers and at least m data layers.

[0141] Table 1 shows the coding rates of at least one control information layer and at least one data layer in a single MCS table. In this case, the base station can indicate an MCS index value using an indicator field in the control signaling (L2 radio resource control (RRC) control signaling or L1 DCI control signaling). Alternatively, the coding rates of at least one control information layer and at least one data layer can be shown in two or more different MCS tables. For example, the coding rate of at least one control information layer can be shown in one MCS table, and the coding rate of at least one data layer can be shown in another MCS table; or, for example, the coding rates of different control information layers within at least one control information layer can be shown in different MCS tables. In this case, the base station needs to indicate the MCS index values ​​of different tables using multiple indicator fields in the control signaling.

[0142] The MCS form in the standard or implementation can be an MCS form that contains some or all of the rows in Table 1 above.

[0143] For example, the sum of the number of at least one control information layer and the number of at least one data layer is the number of energy levels contained in each modulation symbol. For instance, assuming that the number of energy levels contained in each modulation symbol corresponding to the first modulation scheme is M, and Table 1 shows that the number of at least one control information layer is 2 and the number of at least one data layer is m, then M can be equal to the sum of 2 and m.

[0144] One possible implementation is that the energy level of the bits used to carry control information in each of the multiple modulation symbols obtained by the above S312 modulation is greater than or equal to the energy level of the bits used to carry data.

[0145] It should be understood that the higher the energy level of a bit, the higher the transmission reliability of that bit; conversely, the lower the energy level of a bit, the lower the transmission reliability of that bit.

[0146] For example, each modulation symbol includes Q. m Each bit carries control information in this Q. m Data is carried on at least one bit of the Q. m Of the remaining bits in the M bits excluding the at least one bit, the energy level of the at least one bit is the highest energy level among the M energy levels contained in each modulation symbol, Q. m M is a positive integer greater than 1.

[0147] For example, the aforementioned at least one bit may be consecutive or non-consecutive, or the aforementioned at least one bit may be adjacent or not adjacent.

[0148] For example, the first modulation scheme described above is 8ASK, and each modulation symbol includes 3 bits. Each modulation symbol contains 2 energy levels (M), with 2 bits for the first energy level (high energy level) and 1 bit for the second energy level (low energy level). For example, at least one control information layer can have 2 or 1 layers, and at least one data layer can have 1 layer. At least one control information layer can be carried on 2 bits of the high energy level of each modulation symbol, and at least one data layer can be carried on 1 bit of the low energy level of each modulation symbol.

[0149] For example, the first modulation scheme described above is 16QAM, where each modulation symbol includes 4 bits. Each modulation symbol contains 2 energy levels (M), with 2 bits for the first energy level (high energy level) and 2 bits for the second energy level (low energy level). For instance, at least one control information layer can have 2 or 1 layers, and at least one data layer can have 2 or 1 layers. At least one control information layer can be carried on 2 bits of the high energy level of each modulation symbol, and at least one data layer can be carried on 2 bits of the low energy level of each modulation symbol; alternatively, at least one control information layer can be carried on 1 bit of the high energy level and 1 bit of the low energy level of each modulation symbol, and at least one data layer can be carried on another bit of the high energy level and another bit of the low energy level of each modulation symbol.

[0150] For example, the first modulation scheme mentioned above is 64QAM, and each modulation symbol includes 6 bits. The number of energy levels (m) contained in each modulation symbol is 3. The number of bits (X1) for the first energy level (high energy level) is 2, the number of bits (X2) for the second energy level (medium energy level) is 2, and the number of bits (X3) for the third energy level (low energy level) is 2. For example, the number of layers in at least one control information layer can be 2 or 1, and the number of layers in at least one data layer can be 4, 3, 2, or 1. At least one control information layer can be carried on 2 bits of the high energy level in each modulation symbol, and at least one data layer can be carried on 2 bits of the medium energy level and 2 bits of the low energy level in each modulation symbol, such as... Figure 6 The carrying method shown in (a) is as follows; or, at least one control information layer may be carried on one bit of the high energy level and one bit of the medium energy level of each modulation symbol, and at least one data layer may be carried on another bit of the high energy level, another bit of the medium energy level, and two bits of the low energy level of each modulation symbol, such as... Figure 6 The bearing method shown in (b) is as follows.

[0151] One possible implementation is that the data to be transmitted includes a first part of data, which is unencoded, and control information and the first part of data are carried on at least one bit.

[0152] It should be understood that the first part of the data can be one or more of the above-mentioned data layers.

[0153] Taking 64QAM as an example, at least one control information layer can be carried on one bit of the high energy level of each modulation symbol, and the first part of the data can be carried on another bit of the high energy level of each modulation symbol. The remaining data, excluding the first part, can be carried on two bits of the medium energy level and two bits of the low energy level of each modulation symbol. Alternatively, the remaining data layers, excluding the aforementioned data layers, can be carried on two bits of the medium energy level and two bits of the low energy level of each modulation symbol. Figure 7 The load-bearing method shown.

[0154] One possible implementation is that each of the at least one control information layer corresponds to at least one type, and the different control information layers in the at least one control information layer are carried on different energy levels contained in each modulation symbol.

[0155] Taking control information as an example, UCI can include types such as HARQ-ACK, SR, CSI part1, and CSI part4.

[0156] Taking 64QAM as an example, at least one control information layer includes a first control information layer and a second control information layer. The first control information layer corresponds to at least one first control information, and the second control information layer corresponds to at least one second control information. For example, the at least one first control information is HARQ-ACK, and the at least one second control information is SR. HARQ-ACK can be carried on two bits of the high-energy level of each modulation symbol, and SR can be carried on two bits of the medium-energy level of each modulation symbol. Figure 8 The carrying method is shown. For example, the at least one first control information is HARQ-ACK and SR, and the at least one second control information is CSI part1 and CSI part4. HARQ-ACK and SR can be carried on two bits of the high energy level of each modulation symbol, and CSI part1 and CSI part4 can be carried on two bits of the medium energy level of each modulation symbol.

[0157] S314, the transmitting device outputs the above-mentioned modulation symbol stream.

[0158] After modulation is completed, the transmitting device outputs the modulation symbol stream.

[0159] Optionally, the communication method 300 described above may also include a decoding method. This will be explained below with reference to S316 to S320.

[0160] S316, the receiving device acquires the symbol stream to be demodulated, which includes multiple modulation symbols, each of which carries control information and data.

[0161] The way each modulation symbol carries control information and data can be referred to in step S312 above, and will not be repeated here.

[0162] S318, the receiving device demodulates the above-mentioned symbol stream to be demodulated based on the first modulation method to obtain the demodulated control information and data.

[0163] Specifically, the receiving device demodulates the aforementioned symbol stream to be demodulated based on the first modulation scheme to obtain at least one control information layer and at least one data layer.

[0164] It should be understood that the demodulation of the symbol stream to be demodulated by the receiving device based on the first modulation scheme described above is the inverse operation of the modulation of the control information and data by the transmitting device based on the first modulation scheme described above. The bit information of each symbol can be obtained through demodulation. Those skilled in the art can obtain the detailed demodulation steps based on the detailed steps of the modulation described above, and this application will not elaborate on them further.

[0165] S320, the receiving device outputs the demodulated control information and data.

[0166] It should be understood that the receiving device may also need to decode the demodulated control information and data output above.

[0167] For example, the decoding method corresponding to the above method one is as follows: the receiving device merges the above at least one control information layer and the above at least one data layer to obtain a first codeword sequence; the receiving device decodes the first codeword sequence to obtain a decoded codeword sequence.

[0168] For example, the decoding method corresponding to the above method two is as follows: the receiving device decodes the above at least one control information layer to obtain a first decoded codeword sequence; the receiving device decodes the above at least one data layer to obtain a second decoded codeword sequence.

[0169] For example, the decoding method corresponding to the above method three is as follows: the receiving device decodes at least one of the above data layers to obtain the second decoded codeword sequence.

[0170] The decoding of the demodulated control information and data by the receiving device is the inverse operation of the encoding of the first code block, at least one second code block, or at least one third code block by the transmitting device. The original information can be recovered through decoding. Based on the detailed steps of the encoding described above, those skilled in the art can obtain the detailed steps of the decoding, which will not be repeated here.

[0171] The communication method 300 described above can modulate control information and data onto the modulation symbol using the same modulation method, which can reduce the operational complexity of the transmitting and receiving ends.

[0172] It is understood that the steps in the above figures are merely illustrative and are not intended to be strictly limited. Furthermore, the sequence numbers of the processes described above do not imply a specific order of execution; the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0174] It is also understood that some optional features in the various embodiments of this application may not depend on other features in some scenarios, or may be combined with other features in some scenarios, without limitation.

These modules can be software, hardware, or a combination of both. It is understood that the technical features described in the above method embodiments are also applicable to the following apparatus embodiments.
