Furthermore, the optional implementation methods in a particular embodiment can be arbitrarily combined; moreover, the embodiments can be arbitrarily combined, for example, some or all steps of different embodiments can be arbitrarily combined, and a particular embodiment can be arbitrarily combined with the optional implementation methods of other embodiments. In all embodiments of this disclosure, unless otherwise specified or logically conflicting, the terminology and / or descriptions between the embodiments are consistent and can be mutually referenced. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

Similarly, if the descriptive object is a "level," the ordinal numbers preceding "level" in "first level" and "second level" do not restrict the priority between "levels." Furthermore, the number of descriptive objects is not limited by ordinal numbers and can be one or more. For example, in "first device," the number of "devices" can be one or more. Furthermore, the objects modified by different prefixes can be the same or different.

[0119] In some embodiments, access network devices, core network devices, or network devices can be replaced by terminals.

[0124] Figure 1A is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0125] Figure 1A is an architecture diagram of a communication system provided in an embodiment of this disclosure.

[0126] As shown in Figure 1A, the communication system 100 includes a terminal 101 and a network device 102.

[0127] In some embodiments, terminal 101 includes, but is not limited to, at least one of the following: mobile phone, wearable device, Internet of Things device, car with communication function, smart car, tablet computer, computer with wireless transceiver function, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, and wireless terminal in smart home.

[0128] In some embodiments, network device 102 includes access network device and core network device.

[0129] In some embodiments, the access network device is, for example, a node or device that connects a terminal to a wireless network. The access network device may include, but is not limited to, at least one of the following in a 5G communication system: evolved Node B (eNB), next-generation eNB (ng-eNB), next-generation Node B (gNB), node B (NB), home node B (HNB), home evolved node B (HeNB), radio backhaul device, radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), base band unit (BBU), mobile switching center, base station in a 6G communication system, open RAN, cloud RAN, base station in other communication systems, and access node in a Wi-Fi system.

[0130] In some embodiments, the core network equipment may be a single device, multiple devices, or a group of devices, including all or part of a first network element, a second network element, a third network element, a fourth network element, etc. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), a 6G Core Network (6GCN), and a Next Generation Core (NGC).

[0131] In some embodiments, the communication system 100 can be applied to a satellite communication network architecture.

[0132] In some embodiments, in the satellite communication network structure, a ground terminal 101 accesses the network (i.e., establishes a communication connection with the access network equipment) via an air interface (a wireless link between the terminal and the access network equipment). The access network equipment can be deployed on a satellite or on the ground. The satellite is connected to a ground station (or gateway station, earth station) via a wireless link. Access network equipment deployed on the ground can connect to the ground station to communicate with the satellite. The ground station or the access network equipment deployed on the ground can connect to the core network equipment via wired or wireless means. Wireless links can also exist between satellites. If the satellite only has a transparent forwarding mode (the corresponding access network equipment is deployed on the ground), then only transparent forwarding can be achieved between satellites. If the access network equipment or some access network equipment functions are deployed on the satellite, then signaling interaction and user data transmission between access network equipment can be completed between satellites.

[0133] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0134] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1A, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1A are illustrative. The communication system may include all or some of the main bodies in FIG1A, or it may include other main bodies outside of FIG1A. The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0135] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), Super 3G, IMT-Advanced, 4th Generation Mobile Communication System (4G), 5th Generation Mobile Communication System (5G), 5G New Radio (NR), 6th Generation Mobile Communication System (6G), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, ultra-wideband (UWB), Bluetooth (a registered trademark), public land mobile network (PLMN) networks, device-to-device (D2D) systems, machine-to-machine (M2M) systems, internet of things (IoT) systems, vehicle-to-everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).

[0136] Shannon's information theory and various channel coding methods, including low-density parity check (LDPC), polar, turbo, and tail-biting convolution coding (TBCC), focus on point-to-point communication. In the presence of fading channels, white noise, and interference, the actual performance differences between channel codes become increasingly smaller.

[0137] As shown in Figure 1B, the multi-source transmission method for multi-source links includes two source nodes (1, 3) and one relay node (2, e.g., a satellite). Ignoring the full-duplex capability of node 2, to achieve interconnection between 1 and 3 (i.e., 1 transmits a data packet 'a' to 3, and 3 transmits another data packet 'b' to 1), the process is as follows: Link i needs to carry data packet 'a', relay node 2 needs to forward it via link ii; Link iii needs to carry data packet 'b', relay node 2 needs to forward it via link iv. The transmission resources of links i to iv are either different in time or frequency domain. Taking the transmission resources of links i to iv required for interconnection as a baseline, how to save transmission resources is a problem that urgently needs to be solved.

[0138] Based on this, this disclosure provides a method and apparatus for receiving and sending information. The method, executed by a first device, includes: receiving first information sent by a second device; receiving second information sent by a third device; determining third information based on the first and second information; sending the third information to the second device; and sending the third information to the third device. Therefore, compared to the first device sending the first information to the third device separately and the second information directly to the second device, this reduces link resource overhead, increases information transmission throughput, and improves the performance of the communication system.

[0139] Figure 2A is an interactive schematic diagram illustrating an information receiving and sending method according to an embodiment of the present disclosure. As shown in Figure 2A, the present disclosure relates to an information receiving and sending method, which includes:

[0140] S201A, the first device sends the first resource configuration information to the second device.

[0141] In some embodiments, the second device receives first resource configuration information sent by the first device, but is not limited thereto. The second device may also receive first resource configuration information sent by other entities other than the first device, in which case S201A can be omitted.

[0142] In some embodiments, the second device obtains the first resource configuration information specified by the protocol, in which case S201A can be omitted.

[0143] In some embodiments, the second device obtains the first resource configuration information from the upper layer(s), in which case S201A can be omitted.

[0144] In some embodiments, the second device processes the information to obtain the first resource configuration information, in which case S201A can be omitted.

[0145] In some embodiments, the second device autonomously implements the function indicated by the first resource configuration information, or the above function is a default or default value, in which case S201A can be omitted.

[0146] In some embodiments, when a first device determines that it needs to communicate with a second device, it sends first resource configuration information to the second device. The first resource configuration information indicates the resources used by the second device to communicate with the first device, including at least one of time-domain resources and frequency-domain resources. Optionally, communication between the second device and the first device includes at least one of the following: the second device receiving information sent by the first device and the second device sending information to the first device.

[0147] In some embodiments, upon receiving a first request message from a second device, wherein the first request message requests the first device to configure transmission resources for communicating with the second device, the first device sends first resource configuration information to the second device. The first resource configuration information indicates the resources used by the second device to communicate with the first device, including at least one of time-domain resources and frequency-domain resources. Optionally, communicating with the first device includes at least one of the following: the second device receiving information from the first device and the second device sending information to the first device.

[0148] In some embodiments, when the first device receives indication information from another device (e.g., a third device) other than the first and second devices, and the indication information instructs the first device to configure transmission resources for communicating with the second device, the first device sends first resource configuration information to the second device. The first resource configuration information indicates the resources used by the second device to communicate with the first device, including at least one of time-domain resources and frequency-domain resources. Optionally, communicating with the first device includes at least one of the following: the second device receiving information sent by the first device and the second device sending information to the first device.

[0149] In some embodiments, the first device is at least one of a satellite, a terminal, an access network device, and a ground station.

[0150] In some embodiments, the second device is at least one of a satellite, a terminal, an access network device, and a ground station.

[0151] In some embodiments, the first device is a satellite and the second device is a terminal; or the first device is a satellite and the second device is a ground station.

[0152] In some embodiments, the first resource configuration information is used to indicate at least one of the following: a first time domain resource for the second device to send first information to the first device; a first frequency domain resource for the second device to send first information to the first device; a second time domain resource for the second device to receive third information sent by the first device; and a second frequency domain resource for the second device to receive third information sent by the first device.

[0153] In this embodiment of the disclosure, the first resource configuration information is used to instruct the second device to send the first information to the first device using a first time-domain resource. Optionally, the first time-domain resource includes a start time-domain position and a duration, or the first time-domain resource includes a start time-domain position and an end time-domain position.

[0154] In this embodiment of the disclosure, the first resource configuration information is used to instruct the second device to send the first information to the first device in the first frequency domain resource. Optionally, the first frequency domain resource includes a starting frequency domain position and a frequency domain range size, or the first frequency domain resource includes a starting frequency domain position and an ending frequency domain position.

[0155] In this embodiment of the disclosure, the first resource configuration information is used to instruct the second device to receive the second time-domain resource of the third information sent by the first device. Optionally, the second time-domain resource includes a start time-domain position and a duration, or the second time-domain resource includes a start time-domain position and an end time-domain position.

[0156] In this embodiment of the disclosure, the first resource configuration information is used to instruct the second device to receive the second frequency domain resources of the third information sent by the first device. Optionally, the second frequency domain resources include a starting frequency domain position and a frequency domain range size, or the second frequency domain resources include a starting frequency domain position and an ending frequency domain position.

[0157] In some embodiments, the first resource configuration information includes at least one of the following: beam information, a synchronization signal block (SSB) that has a quasi-co-located (QCL) relationship with the beam, and configuration information including transmission configuration indicator (TCI) information of channel state information reference signal (CSI-RS) resources.

[0158] In some embodiments, the time interval between the first time domain resource and the second time domain resource in the time domain location is less than or equal to the first duration and is divisible by the first duration, wherein the first duration is the duration for which the first device acts as a relay node between the second device and the third device to provide services to the second device.

[0159] It is understandable that when the first device receives the first information sent by the second device and then sends the third information to the second device, there is a time interval between the second device sending the first information and receiving the third information because the first information and the third information need to be transmitted before they can be received by the receiver.

[0160] In this embodiment of the disclosure, the time interval between the first time domain resource and the second time domain resource in the time domain location is less than or equal to the first duration, wherein the first duration is the duration for which the first device acts as a relay node between the second device and the third device and provides services to the second device.

[0161] It is understandable that when the time interval between the first and second time domain resources is longer than the first duration, if the first device receives the first information sent by the second device on the first time domain resource and sends the third information to the second device on the second time domain resource, the first device can no longer act as a relay node between the second and third devices to provide services to the second device. In other words, the third information sent by the first device to the second device on the second time domain resource cannot be received by the second device, leading to information transmission failure. This situation needs to be avoided. Therefore, in this embodiment, the time interval between the first and second time domain resources is less than or equal to the first duration. Optionally, the time interval between the first and second time domain resources is divisible by the first duration.

[0162] In some embodiments, the third device is at least one of a satellite, a terminal, an access network device, and a ground station.

[0163] In some embodiments, the first device is a satellite, the second device is a terminal, and the third device is a ground station; or the first device is a satellite, the second device is a ground station, and the third device is a terminal.

[0164] In some embodiments, where the first device is a satellite and the second device is a terminal, the first device may also receive instruction information sent by a third device, such as a ground station. If the instruction information is used to instruct the first device to send the first resource configuration information to the second device, the first device sends the first resource configuration information to the second device.

[0165] S202A, the first device sends the second resource configuration information to the third device.

[0166] S202A and S201A can be executed in interchangeably or simultaneously.

[0167] In some embodiments, the third device receives second resource configuration information sent by the first device, but is not limited thereto. The third device may also receive second resource configuration information sent by other entities other than the first device, in which case S202A can be omitted.

[0168] In some embodiments, the third device obtains the second resource configuration information specified by the protocol, in which case S202A can be omitted.

[0169] In some embodiments, the third device obtains the second resource configuration information from the upper layer(s), in which case S202A can be omitted.

[0172] In some embodiments, when the first device determines that it needs to communicate with the third device, it sends second resource configuration information to the third device. The second resource configuration information indicates the resources used by the third device to communicate with the first device, including at least one of time-domain resources and frequency-domain resources. Optionally, communication between the third device and the first device includes at least one of the third device receiving information sent by the first device and the third device sending information to the first device.

[0173] In some embodiments, upon receiving a second request message from a third device, wherein the second request message requests the first device to configure transmission resources for communicating with the third device, the first device sends second resource configuration information to the third device. The second resource configuration information indicates the resources used by the third device to communicate with the first device, including at least one of time-domain resources and frequency-domain resources. Optionally, communicating with the first device includes at least one of the third device receiving information from the first device and the third device sending information to the first device.

[0174] In some embodiments, when the first device receives indication information from another device (e.g., the second device) other than the first device and the third device, and the indication information instructs the first device to configure transmission resources for communication with the third device, the first device sends second resource configuration information to the third device. The second resource configuration information indicates the resources used by the third device to communicate with the first device, including at least one of time-domain resources and frequency-domain resources. Optionally, communication between the third device and the first device includes at least one of the third device receiving information sent by the first device and the third device sending information to the first device.

[0175] In some embodiments, the third device is at least one of a satellite, a terminal, an access network device, and a ground station.

[0176] In some embodiments, the first device is a satellite and the third device is a terminal; or the first device is a satellite and the third device is a ground station.

[0177] In some embodiments, the second resource configuration information is used to indicate at least one of the following: a third time-domain resource for the third device to send second information to the first device; a third frequency-domain resource for the third device to send second information to the first device; a fourth time-domain resource for the third device to receive the third information sent by the first device; and a fourth frequency-domain resource for the third device to receive the third information sent by the first device.

[0178] In this embodiment of the disclosure, the second resource configuration information is used to instruct the third device to send the second information to the first device using a third time-domain resource. Optionally, the third time-domain resource includes a start time-domain position and a duration, or the third time-domain resource includes a start time-domain position and an end time-domain position.

[0179] In this embodiment of the disclosure, the second resource configuration information is used to instruct the third device to send the second information to the first device via a third frequency domain resource. Optionally, the third frequency domain resource includes a starting frequency domain position and a frequency domain range size, or the third frequency domain resource includes a starting frequency domain position and an ending frequency domain position.

[0180] In this embodiment of the disclosure, the second resource configuration information is used to instruct the third device to receive the fourth time-domain resource of the third information sent by the first device. Optionally, the fourth time-domain resource includes a start time-domain position and a duration, or the fourth time-domain resource includes a start time-domain position and an end time-domain position.

[0181] In this embodiment of the disclosure, the second resource configuration information is used to instruct the third device to receive the fourth frequency domain resource of the third information sent by the first device. Optionally, the fourth frequency domain resource includes a starting frequency domain position and a frequency domain range size, or the fourth frequency domain resource includes a starting frequency domain position and an ending frequency domain position.

[0182] In some embodiments, the second resource configuration information includes at least one of the following: beam information, a synchronization signal block (SSB) that has a quasi-co-located (QCL) relationship with the beam, and configuration information including transmission configuration indicator (TCI) information for channel state information reference signal (CSI-RS) resources.

[0183] In some embodiments, the time interval between the third time domain resource and the fourth time domain resource in the time domain location is less than or equal to the first time duration and is divisible by the first time duration, wherein the first time duration is the duration for which the first device acts as a relay node between the second device and the third device to provide services to the third device.

[0184] It is understandable that when the first device receives the second information sent by the third device and then sends the third information to the third device, there is a time interval between the third device sending the second information and receiving the third information because the second and third information need to undergo transmission time before they can be received by the receiver.

[0185] In this embodiment of the disclosure, the time interval between the third time domain resource and the fourth time domain resource in the time domain location is less than or equal to the first time duration, wherein the first time duration is the duration for which the first device acts as a relay node between the second and third devices and provides services to the third device.

[0186] It is understandable that when the time interval between the third and fourth time domain resources is longer than the first time domain, if the first device receives the second information sent by the third device on the third time domain resource and sends the third information to the third device on the fourth time domain resource, the first device can no longer act as a relay node between the second and third devices to provide services to the third device. In other words, the third information sent by the first device to the third device on the fourth time domain resource cannot be received by the third device, leading to information transmission failure. This situation needs to be avoided. Therefore, in this embodiment, the time interval between the third and fourth time domain resources is less than or equal to the first time domain. Optionally, the time interval between the third and fourth time domain resources is divisible by the first time domain.

[0191] In some embodiments, the first device obtains second instruction information as specified by the protocol, in which case S203A can be omitted.

[0192] In some embodiments, the first device obtains second instruction information from a higher layer, in which case S203A can be omitted.

[0193] In some embodiments, the first device processes the information to obtain the second instruction information, in which case S203A can be omitted.

[0194] In some embodiments, the first device autonomously implements the function indicated by the second instruction information, or the above function is a default or default value, in which case S203A can be omitted.

[0210] In the embodiments of the present disclosure, the second indication information is configured to indicate that the determining manner in which the first device determines third information according to first information and second information is: determining that the length of a second bit stream is less than the length of a first bit stream, performing bit padding on the second bit stream to obtain a target second bit stream having the same length as the first bit stream, performing bit XOR on the target second bit stream and the first bit stream, and determining the third information.

[0211] In the embodiments of the present disclosure, the second indication information is configured to indicate that the determining manner in which the first device determines third information according to first information and second information is: determining that the length of a first bit stream is less than the length of a second bit stream, performing bit padding on the first bit stream to obtain a target first bit stream having the same length as the second bit stream, performing bit XNOR on the target first bit stream and the second bit stream, and determining the third information.

[0212] In the embodiments of the present disclosure, the second indication information is configured to indicate that the determining manner in which the first device determines third information according to first information and second information is: determining that the length of a second bit stream is less than the length of a first bit stream, performing bit padding on the second bit stream to obtain a target second bit stream having the same length as the first bit stream, performing bit XNOR on the target second bit stream and the first bit stream, and determining the third information.

[0213] For example, the first bit stream of the first information is {b1, b2, b3, …, b n}, and the second bit stream of the second information is {c1, c2, c3, …, c m}, denote q = max(m, n). Denote the aggregated bit stream as {s1, s2 …, s q}. Taking n < m, that is q = m, (the case of m > n is similar) as an example for explanation: firstly, by means of bit padding, {b1, b2, b3, …, b n} is complemented to {b1, b2, b3, …, b n , p n+1 , p n+2 , …, p q}, then {b1, b2, b3, …, b n , p n+1 , p n+2 , …, p q} and {c1, c2, c3, …, c m} are subjected to bit XOR to obtain a new bit stream, and the third information is determined.

[0214] For example, the second bit stream of the second information is {b1, b2, b3, …, b n}, and the first bit stream of the first information is {c1, c2, c3, …, c m}, let q=max(m,n). Let the aggregated bit stream be {s1, s2, ..., s q}. Taking n < m, i.e., q = m, (the case where m > n is similar) as an example for explanation, first, by means of padding bits, {b1,b2,b3,…,b n} is completed into {b1,b2,b3,…,b n ,p n+1 ,p n+2 ,…,p q}, then perform bitwise XNOR on {b1,b2,b3,…,b n ,p n+1 ,p n+2 ,…,p q} and {c1,c2,c3,…,c m} to obtain a new bit stream, and the third information is determined.

[0215] In some embodiments, the second indication information includes at least one of the following: the number of bits of a transport block; the number of bits of a coding block; the number of coding blocks; the number of coding block groups; the number of bit padding bits required for a transport block; the number of bit padding bits required for a coding block; the number of bit padding bits required for a coding block group; and a coding rate.

[0216] In the embodiments of the present disclosure, the determining manner in which the second indication information is used to instruct the first device to determine third information based on first information and second information is: determining a first modulation symbol obtained by mapping a first bit stream of the first information, and a second modulation symbol obtained by mapping a second bit stream of the second information, superimposing the first modulation symbol and the second modulation symbol, and determining the third information.

[0217] In some embodiments, the determining manner further includes: directly superimposing the first modulation symbol and the second modulation symbol to determine the third information; or determining, according to the value of a corresponding constellation point that the first modulation symbol is mapped to in a constellation diagram, a first manner for performing symbol transformation on the second modulation symbol, and after performing symbol transformation on the second modulation symbol according to the first manner, superimposing the transformed second modulation symbol with the first modulation symbol to determine the third information; or determining, according to the value of a corresponding constellation point that the second modulation symbol is mapped to in a constellation diagram, a second manner for performing symbol transformation on the first modulation symbol, and after performing symbol transformation on the first modulation symbol according to the second manner, superimposing the transformed first modulation symbol with the second modulation symbol to determine the third information; or cascading a first bit sequence corresponding to the first modulation symbol and a second bit sequence corresponding to the second modulation symbol to determine the third information.

[0218] In this embodiment of the disclosure, the second indication information is used to instruct the first device to determine the third information based on the first information and the second information in the following manner: determine the first modulation symbol obtained by mapping the first bit stream obtained by decoding the first information, and the second modulation symbol obtained by mapping the second bit stream obtained by decoding the second information, and directly superimpose the first modulation symbol and the second modulation symbol to determine the third information.

[0219] For example, as shown in Figure 3A, the determination method is as follows: The first device determines the first modulation symbol obtained by mapping the first bit stream obtained by decoding the first information. From the coordinate system, the first modulation symbol (shown in the leftmost figure of Figure 3A) is: 10->(-2,2); 00->(2,2); 11->(-2,-2); 01->(2,-2), and the second modulation symbol obtained by mapping the second bit stream obtained by decoding the second information. From the coordinate system, the second modulation symbol (shown in the middle figure of Figure 3A) is: 10->(-1,1); 00->(1,1); 11->(-1,-1); 01->(1,-1). The first modulation symbol and the second modulation symbol are directly superimposed (as shown in the rightmost figure of Figure 3A): 0011->(1,1); 1100->(-1,-1)..., and the third information is determined.

[0220] It is understandable that directly superimposing the first modulation symbol and the second modulation symbol by the first device will result in a non-Gray mapping problem. Based on this, in this embodiment of the present disclosure, the determination method further includes: determining a first method for symbol transformation of the second modulation symbol based on the value of the corresponding constellation point mapped to the constellation diagram of the first modulation symbol, and superimposing the second modulation symbol with the first modulation symbol after performing symbol transformation according to the first method to determine third information; or determining a second method for symbol transformation of the first modulation symbol based on the value of the corresponding constellation point mapped to the constellation diagram of the second modulation symbol, and superimposing the first modulation symbol with the second modulation symbol after performing symbol transformation according to the second method to determine third information, which can solve the non-Gray mapping problem caused by direct superposition.

[0221] In this embodiment of the disclosure, the second indication information is used to instruct the first device to determine the method of determining the third information based on the first information and the second information as follows: determine the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information; determine the first method of symbol transformation of the second modulation symbol based on the value of the corresponding constellation point in the constellation diagram according to the first modulation symbol; and after performing symbol transformation on the second modulation symbol according to the first method, superimpose it with the first modulation symbol to determine the third information.

[0222] In this embodiment of the disclosure, the second indication information is used to instruct the first device to determine the method of determining the third information based on the first information and the second information as follows: determine the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information; determine the second method of symbol transformation of the first modulation symbol based on the value of the corresponding constellation point in the constellation diagram according to the second modulation symbol; and after performing symbol transformation on the first modulation symbol according to the second method, superimpose it with the second modulation symbol to determine the third information.

[0223] In this embodiment of the disclosure, the determination method indicated by the second indication information is as follows: determining the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information; determining the first method of symbol transformation of the second modulation symbol based on the value of the corresponding constellation point in the constellation diagram according to the first modulation symbol; and superimposing the second modulation symbol with the first modulation symbol after performing symbol transformation according to the first method to determine the third information.

[0224] Specifically, based on the first modulation symbol, the value of the corresponding constellation point mapped to the constellation diagram is used to determine a first method for symbol transformation of at least one of the real and imaginary parts of the second modulation symbol, and after the symbol transformation of at least one of the real and imaginary parts of the second modulation symbol is completed according to the first method, the components are superimposed to determine the third information.

[0225] For example, as shown in FIG3B, based on the value of the corresponding constellation point mapped to the constellation diagram of the first modulation symbol, the method of symbol transformation of at least one of the real part (I path) and imaginary part (Q path) of the second modulation symbol is determined, wherein (I path and Q path, I path usually refers to the real part of the complex number, and Q path usually refers to the imaginary part of the complex number).

[0226] Specifically, when the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (2,2), it is determined that neither the real nor imaginary part of the second modulation symbol needs to undergo sign transformation, as shown by symbol B in the upper left corner of Figure 3B. When the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (-2,2), it is determined that the real part of the second modulation symbol undergoes sign transformation (i.e., the real part is multiplied by -1), while the imaginary part does not need to undergo sign transformation, as shown by symbol B in the upper right corner of Figure 3B. When the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (2,-2), it is determined that the real part of the second modulation symbol does not need to undergo sign transformation, while the imaginary part needs to undergo sign transformation (i.e., the imaginary part is multiplied by -1), as shown by symbol B in the lower left corner of Figure 3B. When the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (-2,-2), it is determined that the real part of the second modulation symbol needs to undergo sign transformation (i.e., the real part is multiplied by -1), and the imaginary part needs to undergo sign transformation (i.e., the imaginary part is multiplied by -1), as shown by symbol B in the lower right corner of Figure 3B.

[0227] For example, as shown in Figure 3C, based on the first modulation symbol (shown in the leftmost diagram of Figure 3B): 10->(-2,2); 00->(2,2); 11->(-2,-2); 01->(2,-2) and the second modulation symbol (shown in the middle diagram of Figure 3B): 10->(-1,1); 00->(1,1); 11->(-1,-1); 01->(1,-1), the symbol transformation mode is determined. After the symbol transformation of the first modulation symbol and the second modulation symbol is completed according to the symbol transformation mode, they are superimposed (as shown in the rightmost diagram of Figure 3B) to obtain a composite constellation diagram that conforms to the Gray mapping, thereby determining the third information.

[0228] In this embodiment of the disclosure, the determination method indicated by the second indication information includes: determining a second method for symbol transformation of the first modulation symbol based on the value of the corresponding constellation point mapped to the constellation diagram according to the second modulation symbol; and superimposing the second modulation symbol with the symbol transformation performed on the first modulation symbol according to the second method to determine the third information. See the example described above, which involves determining a first method for symbol transformation of the second modulation symbol based on the value of the corresponding constellation point mapped to the constellation diagram according to the first modulation symbol, and superimposing the second modulation symbol with the first modulation symbol after the symbol transformation performed according to the first method to determine the third information; this will not be repeated here.

[0229] In this embodiment of the disclosure, the second indication information is used to instruct the first device to determine the third information in the following manner: determine the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information, concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, and determine the third information.

[0230] In some embodiments, the determination method further includes: using a first bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information; or the first device using a second bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information; or the first device using a first bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information; or the first device using a second bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information.

[0231] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to take the first bit sequence as the preceding bit sequence, determine the result sequence of bit XORing the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0232] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to use the second bit sequence as the preceding bit sequence, determine the result sequence of performing bit XOR on the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0233] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to take the first bit sequence as the preceding bit sequence, determine the result sequence of bit XORing the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0234] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to use the second bit sequence as the preceding bit sequence, determine the result sequence of bit XORing the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0235] For example, as shown in Figure 3D, the left side represents the first modulation symbol, assuming the value of the first modulation symbol is 10, and the corresponding first bit sequence is 10. The right side represents the second modulation symbol, assuming the value of the second modulation symbol is 10, and the corresponding second bit sequence is 10. As shown in Figure 3E, the first bit sequence is used as the preceding bit sequence, which is 10. The result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence is determined, which is 11. The preceding bit sequence and the result sequence are concatenated, that is, the concatenated bit string is 1011, and the third information is determined.

[0236] For example, the first modulation symbol has a value of 10, corresponding to a first bit sequence of 10; the second modulation symbol has a value of 10, corresponding to a second bit sequence of 10. The first bit sequence is used as the preceding bit sequence, which is 10. The result of performing a bitwise XOR operation on the first and second bit sequences is determined; the result sequence is 00. The preceding bit sequence and the result sequence are concatenated, resulting in a concatenated bit string of 1000, which is used to determine the third information.

[0237] For example, the value of the second modulation symbol is 10, and the corresponding second bit sequence is 10. The value of the first modulation symbol is 11, and the corresponding first bit sequence is 11. The first bit sequence is used as the preceding bit sequence, which is 11. The result sequence of the bit XOR operation between the first bit sequence and the second bit sequence is determined. The result sequence is 01. The preceding bit sequence and the result sequence are concatenated, that is, the concatenated bit string is 1101, and the third information is determined.

[0238] In this embodiment of the disclosure, the determination method includes: performing bit-level operations on the first bit stream after decoding the first information and the second bit stream after decoding the second information to determine the third information.

[0239] In some embodiments, the second indication information is carried by at least one of a broadcast message, a system message, a radio resource control (RRC) message, and a control message.

[0240] S204A, the second device sends the first information to the first device.

[0241] S204A and S203A can be executed in interchangeable order or simultaneously.

[0242] In some embodiments, the first device receives first information sent by the second device, but is not limited thereto. The first device may also receive first information sent by other entities other than the second device, in which case S204A may be omitted.

[0425] In the embodiments of the present disclosure, the second indication information is used to instruct the first device to determine the third information according to the first information and the second information in the following determining manner: determining a first modulation symbol obtained by mapping a first bit stream of the first information and a second modulation symbol obtained by mapping a second bit stream of the second information, superimposing the first modulation symbol and the second modulation symbol, and determining the third information.

[0426] In some embodiments, the determining manner further includes: directly superimposing the first modulation symbol and the second modulation symbol to determine the third information; or determining a first manner of symbol transformation for the second modulation symbol according to a value of a corresponding constellation point when the first modulation symbol is mapped to a constellation diagram, and after performing symbol transformation on the second modulation symbol according to the first manner, superimposing the transformed second modulation symbol with the first modulation symbol to determine the third information; or determining a second manner of symbol transformation for the first modulation symbol according to a value of a corresponding constellation point when the second modulation symbol is mapped to a constellation diagram, and after performing symbol transformation on the first modulation symbol according to the second manner, superimposing the transformed first modulation symbol with the second modulation symbol to determine the third information; or concatenating a first bit sequence corresponding to the first modulation symbol and a second bit sequence corresponding to the second modulation symbol to determine the third information.

[0428] For example, as shown in Figure 3A, the determination method is as follows: The first device determines the first modulation symbol obtained by mapping the first bit stream obtained by decoding the first information. From the coordinate system, the first modulation symbol (shown in the leftmost figure of Figure 3A) is: 10->(-2,2); 00->(2,2); 11->(-2,-2); 01->(2,-2), and the second modulation symbol obtained by mapping the second bit stream obtained by decoding the second information. From the coordinate system, the second modulation symbol (shown in the middle figure of Figure 3A) is: 10->(-1,1); 00->(1,1); 11->(-1,-1); 01->(1,-1). The first modulation symbol and the second modulation symbol are directly superimposed (as shown in the rightmost figure of Figure 3A): 0011->(1,1); 1100->(-1,-1)..., and the third information is determined.

[0429] It is understandable that directly superimposing the first modulation symbol and the second modulation symbol by the first device will result in a non-Gray mapping problem.

[0430] In this embodiment of the disclosure, the second indication information is used to instruct the first device to determine the method of determining the third information based on the first information and the second information as follows: determine the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information; determine the first method of symbol transformation of the second modulation symbol based on the value of the corresponding constellation point in the constellation diagram according to the first modulation symbol; and after performing symbol transformation on the second modulation symbol according to the first method, superimpose it with the first modulation symbol to determine the third information.

[0431] In this embodiment of the disclosure, the second indication information is used to instruct the first device to determine the method of determining the third information based on the first information and the second information as follows: determine the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information; determine the second method of symbol transformation of the first modulation symbol based on the value of the corresponding constellation point in the constellation diagram according to the second modulation symbol; and after performing symbol transformation on the first modulation symbol according to the second method, superimpose it with the second modulation symbol to determine the third information.

[0432] In this embodiment of the disclosure, the determination method indicated by the second indication information is as follows: determining the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information; determining the first method of symbol transformation of the second modulation symbol based on the value of the corresponding constellation point in the constellation diagram according to the first modulation symbol; and superimposing the second modulation symbol with the first modulation symbol after performing symbol transformation according to the first method to determine the third information.

[0433] Specifically, based on the first modulation symbol, the value of the corresponding constellation point mapped to the constellation diagram is used to determine a first method for symbol transformation of at least one of the real and imaginary parts of the second modulation symbol, and after the symbol transformation of at least one of the real and imaginary parts of the second modulation symbol is completed according to the first method, the components are superimposed to determine the third information.

[0434] For example, as shown in FIG3B, based on the value of the corresponding constellation point mapped to the constellation diagram of the first modulation symbol, the method of symbol transformation of at least one of the real part (I path) and imaginary part (Q path) of the second modulation symbol is determined, wherein (I path and Q path, I path usually refers to the real part of the complex number, and Q path usually refers to the imaginary part of the complex number).

[0435] Specifically, when the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (2,2), it is determined that neither the real nor imaginary part of the second modulation symbol needs to undergo sign transformation, as shown by symbol B in the upper left corner of Figure 3B. When the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (-2,2), it is determined that the real part of the second modulation symbol undergoes sign transformation (i.e., the real part is multiplied by -1), while the imaginary part does not need to undergo sign transformation, as shown by symbol B in the upper right corner of Figure 3B. When the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (2,-2), it is determined that the real part of the second modulation symbol does not need to undergo sign transformation, while the imaginary part needs to undergo sign transformation (i.e., the imaginary part is multiplied by -1), as shown by symbol B in the lower left corner of Figure 3B. When the value of the constellation point corresponding to the first modulation symbol in the constellation diagram is (-2,-2), it is determined that the real part of the second modulation symbol needs to undergo sign transformation (i.e., the real part is multiplied by -1), and the imaginary part needs to undergo sign transformation (i.e., the imaginary part is multiplied by -1), as shown by symbol B in the lower right corner of Figure 3B.

[0436] For example, as shown in Figure 3C, based on the first modulation symbol (shown in the leftmost diagram of Figure 3B): 10->(-2,2); 00->(2,2); 11->(-2,-2); 01->(2,-2) and the second modulation symbol (shown in the middle diagram of Figure 3B): 10->(-1,1); 00->(1,1); 11->(-1,-1); 01->(1,-1), the symbol transformation mode is determined. After the symbol transformation of the first modulation symbol and the second modulation symbol is completed according to the symbol transformation mode, they are superimposed (as shown in the rightmost diagram of Figure 3B) to obtain a composite constellation diagram that conforms to the Gray mapping, thereby determining the third information.

[0437] In this embodiment of the disclosure, the determination method indicated by the second indication information includes: determining a second method for symbol transformation of the first modulation symbol based on the value of the corresponding constellation point mapped to the constellation diagram according to the second modulation symbol; and superimposing the second modulation symbol with the symbol transformation performed on the first modulation symbol according to the second method to determine the third information. See the example described above, which involves determining a first method for symbol transformation of the second modulation symbol based on the value of the corresponding constellation point mapped to the constellation diagram according to the first modulation symbol, and superimposing the second modulation symbol with the first modulation symbol after the symbol transformation performed according to the first method to determine the third information; this will not be repeated here.

[0438] In this embodiment of the disclosure, the second indication information is used to instruct the first device to determine the third information in the following manner: determine the first modulation symbol obtained by mapping the first bit stream of the first information and the second modulation symbol obtained by mapping the second bit stream of the second information, concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, and determine the third information.

[0439] In some embodiments, the determination method further includes: using a first bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information; or the first device using a second bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information; or the first device using a first bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information; or the first device using a second bit sequence as a preceding bit sequence, determining the result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence, concatenating the preceding bit sequence and the result sequence to determine third information.

[0440] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to take the first bit sequence as the preceding bit sequence, determine the result sequence of bit XORing the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0441] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to use the second bit sequence as the preceding bit sequence, determine the result sequence of performing bit XOR on the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0442] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to take the first bit sequence as the preceding bit sequence, determine the result sequence of bit XORing the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0443] In this embodiment of the disclosure, the second indication information is used to instruct the first device to concatenate the first bit sequence corresponding to the first modulation symbol and the second bit sequence corresponding to the second modulation symbol, that is, to use the second bit sequence as the preceding bit sequence, determine the result sequence of bit XORing the first bit sequence and the second bit sequence, concatenate the preceding bit sequence and the result sequence, and determine the third information.

[0444] For example, as shown in Figure 3D, the left side represents the first modulation symbol, assuming the value of the first modulation symbol is 10, and the corresponding first bit sequence is 10. The right side represents the second modulation symbol, assuming the value of the second modulation symbol is 10, and the corresponding second bit sequence is 10. As shown in Figure 3E, the first bit sequence is used as the preceding bit sequence, which is 10. The result sequence of performing a bit XOR operation on the first bit sequence and the second bit sequence is determined, which is 11. The preceding bit sequence and the result sequence are concatenated, that is, the concatenated bit string is 1011, and the third information is determined.

[0445] For example, the first modulation symbol has a value of 10, corresponding to a first bit sequence of 10; the second modulation symbol has a value of 10, corresponding to a second bit sequence of 10. The first bit sequence is used as the preceding bit sequence, which is 10. The result of performing a bitwise XOR operation on the first and second bit sequences is determined; the result sequence is 00. The preceding bit sequence and the result sequence are concatenated, resulting in a concatenated bit string of 1000, which is used to determine the third information.

[0446] For example, the value of the second modulation symbol is 10, and the corresponding second bit sequence is 10. The value of the first modulation symbol is 11, and the corresponding first bit sequence is 11. The first bit sequence is used as the preceding bit sequence, which is 11. The result sequence of the bit XOR operation between the first bit sequence and the second bit sequence is determined. The result sequence is 01. The preceding bit sequence and the result sequence are concatenated, that is, the concatenated bit string is 1101, and the third information is determined.

[0447] In this embodiment of the disclosure, the determination method includes: performing bit-level operations on the first bit stream after decoding the first information and the second bit stream after decoding the second information to determine the third information.

[0515] To facilitate understanding of the embodiments of this disclosure, an exemplary embodiment is provided.

[0516] In the exemplary embodiment, the multi-source transmission method shown in Figure 1B includes two source nodes (1, 3) and one relay node (2, e.g., a satellite). Ignoring the full-duplex capability of node 2, to achieve communication between 1 and 3 (i.e., 1 transmits a data packet a to 3, and 3 transmits another data packet b to 1), the process is as follows: link i needs to carry data packet a, relay node 2 needs to forward it via link ii, link iii needs to carry data packet b, and relay node 2 needs to forward it via link iv. The data packets carried by (i, ii, iii, iv) are either different time resources or different frequency domain resources.

[0517] The multi-source transmission method shown in Figure 3F includes two source nodes (1,3) and one relay node (2, e.g., a satellite). Ignoring the full-duplex capability of node 2, to achieve communication between nodes 1 and 3 (i.e., 1 transmits a data packet 'a' to 3, and 3 transmits another data packet 'b' to 1), the process is as follows: Link i between node 1 and node 2 needs to carry data packet 'a', and Link ii between node 3 and node 2 needs to carry data packet 'b'. Relay node 2 broadcasts an aggregated data packet (a+b) to nodes (1,3) via Link 3. Links i and ii require different time-frequency resources, while Link iii can use shared time-frequency resources for broadcasting. Nodes 1 and 3 receive the aggregated data packet and eliminate their respective local data packets to obtain the data packet they need; that is, node 1 receives data packet 'b', and node 3 receives data packet 'a'. Compared to the link resource overhead in Figure 1B, the shared time-frequency broadcast resources relied upon by Link iii can significantly improve throughput.

[0518] Multi-source / network coding can be performed at the MAC layer, physical layer, or transport signal layer. If performed at the MAC layer, decoding and MAC reassembly, as well as packet concatenation, need to be completed at intermediate nodes. If performed at the physical layer, decoding, bit XORing, and re-encoding processes need to be completed at intermediate nodes. If performed at the transport signal layer, the mapping symbol from the aggregated bits to the superimposed modulation symbols needs to be agreed upon between nodes 1 and 3. This can be achieved through configuration or dynamic indication via control information to ensure consistent understanding of relevant information.

[0519] The transmission process mainly involves the configuration and indication of time-domain / frequency-domain transmission resources. For links i and iii, from node 1, they belong to uplink and downlink respectively. If different time-domain information is used for transmission, a new transmission structure can be defined for satellite communication, namely, a certain uplink transmission used to carry link i. After at least a certain switching time Ts (note: Ts is determined by the RTT from node 1 to node 2), the downlink transmission time period is used to carry link iii. To ensure that all transmissions involve a unified intermediate node 2, the following constraints need to be considered in the transmission time structure. Let the time when the satellite acts as a relay node between nodes 1 and 3 be Tdwell. Tdwell refers to the time when the satellite and the same ground station and the central beam are still in the same area. The total transmission time should include two parts: at least transmission time, switching time, and reception time, regardless of which node it is from. Although the transmission time can be distinguished from both uplink and downlink dimensions, the reception time is difficult to distinguish because it is a receiving behavior for different nodes.

[0520] In satellite communication systems, frequency domain resources are primarily carried by beams. This frequency domain information can be obtained by configuring / indicating beam-related information, such as beam number, the synchronization signal block (SSB) associated with the beam quasi-co-located (QCL), or the channel state information reference signal (CSI-RS). For link iii, beam information can be configured via node 3 or node 2. Corresponding indications can be initiated via either node 3 or node 2. Beam information indications initiated by node 3 can be achieved using the following methods.

[0521] This disclosure provides a data transmission method applied to a first transmission node and a third transmission node. The first and third transmission nodes send the data signal to be transmitted to a second transmission node, and the second transmission node then transmits the aggregated data signal to the first and third transmission nodes.

[0522] Let link 1 be the data signal that the first node sends to the second node, link 2 be the data signal that the third node sends to the second node, and link 3 be the aggregated data signal that the second node sends to the first and third nodes.

[0523] The aggregation signal here includes at least the concatenation of data packets, bit-level operations, superposition of bit-mapped modulation symbols, and superposition of signals.

[0524] Example 1 (Superposition of modulation symbols mapped to bits)

[0525] Sub-method 0: Symbolic operations, directly superimposed.

[0526] As shown in Figure 3A, assuming that both node 3 and node 1 transmit to node 2 using quadrature phase shift keying (QPSK) modulation, the constellation modulation diagram of node 3 is shown on the left, and the constellation modulation diagram of node 1 is shown on the right. From the coordinate system perspective:

[0527] Node 3: 10->(-2,2); 00->(2,2); 11->(-2,-2); 01->(2,-2)

[0528] Node 1: 10->(-1,1); 00->(1,1); 11->(-1,-1); 01->(1,-1)

[0529] Example of node 2 overlay operation: 0011->(1,1); 1100->(-1,-1)...

[0530] The main problem with this method is that it lacks Gray mapping features, which affects demodulation performance.

[0531] Sub-method 1: Symbolic operation, mirror transformation.

[0532] To address the non-Gray mapping problem in sub-method 0, as shown in Figures 3B and 3C, one approach is to perform a mirror transformation on the modulation symbol corresponding to node 1. The mirror transformation method varies depending on the constellation point of node 3.

[0533] - When node 3 sends the symbol (2, 2), node 1 does not make any changes;

[0534] When node 3 sends the symbol (-2,2), node 1 performs a horizontal transformation, i.e., x1->-x1;

[0535] When node 3 sends the symbol (2,-2), node 1 performs a vertical transformation, i.e., y1->-y1;

[0536] When node 3 sends the symbol (-2, -2), node 1 performs a 180-degree mirror transformation about the origin, i.e., x1->-x1, y1->-y1.

[0537] Sub-method 2: Bit-level operation, bit XOR.

[0538] As shown in Figures 3D and 3E, the bit sequence corresponding to each modulation symbol of node 3 is still used as the preceding bit sequence. Specifically, the bit sequence of node 3 needs to be concatenated with the transformed bit sequence of node 1. Node 3 transmits (10), and node 1 also transmits (10). The XOR result of the transmitted bits of node 3 and 1 is (11), and the concatenated bit string is (1011).

[0539] Example 2 (Bit-level operations)

[0540] Bit-level operations include BCH encoding, Hanming code, bit XOR encoding, Reed-Solomon (RS) encoding, indexed modulation (IM) coding, digital fountain code encoding, symbol superposition encoding, network coding, etc. Taking bit XOR as an example, the superposition operation is briefly described as follows:

[0541] Let the bitstream from node 1 to node 2 be {b1, b2, b3, ..., b}. n The bitstream from node 3 to node 2 is {c1, c2, c3, ..., c}. m Let q = max(m,n). Let the aggregated bitstream be {s1, s2, ..., sn}. q}. With n<m(m> Similarly, taking the example of n, we first use padding to fill in the bits {b1,b2,b3,…,b}. n Complete to {b1,b2,b3,…,b} n ,p n+1 ,p n+2 ,…,p q Then for {b1,b2,b3,…,b n ,p n+1 ,p n+2 ,…,p q} and {c1,c2,c3,…,c m Perform a bitwise XOR (modulo-2 addition) to obtain a new bit stream.

[0542] This method requires nodes 1 and 3 to reach a consensus on one or more of the following: the number of bits in the transport block, the number of bits in the coding block, the number of coding blocks, the number of zero-padding bits in the coding block group, and the coding rate. Simultaneously, the symbol modulation order used by nodes 1, 2, and 3 needs to be agreed upon through a mechanism, such as broadcast messages, system messages, RRC messages, or control information.

[0543] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0544] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0545] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable. For example, the processor is a hardware circuit implemented using an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document and configuring the hardware circuit can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. Furthermore, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a Neural Network Processing Unit (NPU), a Tensor Processing Unit (TPU), or a Deep Learning Processing Unit (DPU).
