Description

Communication method and device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 20, 2023, with application number 202311772419.4 and application name “A Communication Method and Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0003] Control information is multiplexed onto the data channel. For example, when uplink control information (UCI) is multiplexed onto the physical uplink shared channel (PUSCH) for transmission, the following rules can be met. For example, the control information is only transmitted on orthogonal frequency division multiplexing (OFDM) symbols that do not transmit a demodulation reference signal (DMRS). The rules met when the above-mentioned control information is multiplexed onto the data channel for transmission are based on the half-duplex area, that is, when only the half-duplex area exists, how to transmit the control information on the data channel? When both full-duplex and half-duplex areas exist and the full-duplex area has both uplink and downlink transmissions, how to multiplex the control information onto the data channel for transmission is a technical problem that is being solved by people in this field. Summary of the Invention

[0004] The present application proposes a communication method and apparatus, which can multiplex control information onto a data channel for transmission when the data channel contains both a full-duplex area and a non-full-duplex area, thereby ensuring the transmission reliability of the control information.

[0005] In a first aspect, an embodiment of the present application provides a communication method, the method comprising: determining a data channel including a full-duplex area and a non-full-duplex area; and multiplexing control information and data information into the data channel according to a mapping rule.

[0006] The method can be applied to the first device, including being executed by the first device, or by a component in the first device (for example, a processor, a chip, or a chip system, etc.), or by a logic module or software that can implement all or part of the functions of the first device.

[0007] Optionally, a data channel can also be output.

[0008] Optionally, the control information may be uplink control information (UCI), the data information may be uplink data information, and the data channel may be a physical uplink shared channel (PUSCH). Accordingly, multiplexing the control information and data information onto the data channel according to the mapping rule may be understood as mapping the UCI and uplink data information onto the PUSCH according to the mapping rule, or may be understood as mapping the encoded UCI bits and uplink data information onto the PUSCH according to the mapping rule.

[0009] Optionally, this method can be applied to low-latency and high-reliability scenarios, such as ultra-high-reliability low-latency communication (URLLC), without limiting the specific application scenarios.

[0010] In the above method, through the above manner, when the data channel includes both a full-duplex area and a non-full-duplex area, the control information and the data information can be multiplexed onto the data channel for transmission, thereby ensuring the transmission reliability of the control information.

[0011] In one possible implementation, the control information includes first information and second information, and multiplexing the control information and data information to the data channel according to the mapping rule includes one or more of the following: multiplexing the first information to the non-full-duplex area according to the mapping rule, multiplexing the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, multiplexing part or all of the data information to the non-full-duplex area according to the mapping rule, or multiplexing part or all of the data information to the non-full-duplex area and the full-duplex area according to the mapping rule.

[0012] In yet another possible implementation, the full-duplex area includes a sub-band full-duplex area.

[0013] In another possible implementation, the first information includes one or more of the following: hybrid automatic repeat request confirmation HARQ-ACK, or the first part of channel state information CSI-part1; the second information includes one or more of the following: HARQ-ACK, CSI-part1, or the second part of channel state information CSI-part2.

[0014] In another possible implementation, the mapping rule includes: a starting position of resource mapping carrying HARQ-ACK is determined based on a starting position of resources carrying a demodulation reference signal DMRS.

[0015] In another possible implementation, the resources carrying HARQ-ACK are mapped starting from the first orthogonal frequency division multiplexing OFDM symbol after the first DMRS; or the resources carrying HARQ-ACK are mapped on the first OFDM symbol containing DMRS; or the resources carrying HARQ-ACK are mapped starting from the first OFDM symbol before the first DMRS.

[0016] In another possible implementation, multiplexing the first information to the non-full-duplex area according to the mapping rule includes: multiplexing the HARQ-ACK and / or CSI-part1 in the first information to the non-full-duplex area according to the mapping rule. Optionally, it can be understood that the encoded HARQ-ACK bits and / or the encoded CSI-part1 bits in the first information are multiplexed to the non-full-duplex area according to the mapping rule.

[0017] In the above method, since the full-duplex area has both uplink and downlink transmissions, the uplink and downlink interference is more serious, and the channel environment of the full-duplex area is worse than the channel environment of the non-full-duplex area. By multiplexing the first information to the non-full-duplex area according to the mapping rule, for example, the first information can be preferentially multiplexed to the non-full-duplex area, thereby ensuring the reliability of the HARQ-ACK and / or CSI-part1 transmission in the first information.

[0018] In another possible implementation, when the number of resource elements RE used by the HARQ-ACK or CSI-part1 in the first information in one symbol is less than or equal to half of the number of available REs in the non-full-duplex area, the HARQ-ACK or CSI-part1 in the first information is uniformly mapped on the available REs in the non-full-duplex area; when the number of RE used by the HARQ-ACK or CSI-part1 in the first information in one symbol is greater than half of the number of available REs in the non-full-duplex area, the HARQ-ACK or CSI-part1 in the first information is continuously mapped on the available REs in the non-full-duplex area.

[0019] Optionally, it can be understood that: when the number of REs used for the encoded HARQ-ACK bits or encoded CSI-part1 bits in the first information in a symbol is less than or equal to half of the number of available resource elements RE in the non-full-duplex area, the encoded HARQ-ACK bits or encoded CSI-part1 bits in the first information are uniformly mapped on the available REs in the non-full-duplex area; when the number of REs used for the encoded HARQ-ACK bits or encoded CSI-part1 bits in the first information in a symbol is greater than half of the number of available REs in the non-full-duplex area, the encoded HARQ-ACK bits or encoded CSI-part1 bits in the first information are continuously mapped on the available REs in the non-full-duplex area.

[0020] In the above method, the HARQ-ACK or CSI-part1 in the first information is evenly mapped to the REs in the non-full-duplex area, which can obtain diversity gain and improve channel quality.

[0021] In another possible implementation, multiplexing the second information to the non-full-duplex area and the full-duplex area according to the mapping rule includes: multiplexing one or more items of the second information to the non-full-duplex area and the full-duplex area according to the mapping rule. Optionally, it can be understood that the encoded HARQ-ACK bits and / or the encoded CSI-part1 bits and / or the encoded CSI-part2 bits in the second information are multiplexed to the non-full-duplex area and the full-duplex area according to the mapping rule.

[0022] In another possible implementation, the mapping rule includes: when the number of REs used for HARQ-ACK, CSI-part1 or CSI-part2 in the second information in one symbol is less than or equal to half of the number of available REs in the full-duplex area and the non-full-duplex area, the HARQ-ACK, CSI-part1 or CSI-part2 in the second information is uniformly mapped on the available REs in the full-duplex area and the non-full-duplex area; when the number of REs used for HARQ-ACK, CSI-part1 or CSI-Part2 in the second information in one symbol is greater than half of the number of available REs in the full-duplex area and the non-full-duplex area, the HARQ-ACK, CSI-part1 or CSI-part2 in the second information is continuously mapped on the available REs in the full-duplex area and the non-full-duplex area.

[0023] Optionally, it can be understood that the mapping rule includes: when the number of used REs of the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-part2 bit in the second information in a symbol is less than or equal to half of the number of available REs in the full-duplex area and the non-full-duplex area, the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-part2 bit in the second information is uniformly mapped on the available REs in the full-duplex area and the non-full-duplex area; when the number of used REs of the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-Part2 bit in the second information in a symbol is greater than half of the number of available REs in the full-duplex area and the non-full-duplex area, the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-Part2 bit in the second information is continuously mapped on the available REs in the full-duplex area and the non-full-duplex area.

[0024] In the above method, the HARQ-ACK, CSI-part1 or CSI-part2 in the second information is evenly mapped to REs in the full-duplex area and the non-full-duplex area, which can obtain diversity gain and improve channel quality.

[0026] It should be noted that the number of used REs in any item of the second information across the full-duplex area and the non-full-duplex area in this application can be understood as the number of used REs in any item of the second information across the full-duplex area and the non-full-duplex area.

[0027] In the above method, in this way, the performance loss of the full-duplex area can be compensated and the reliability of the second information transmission can be guaranteed.

The first expansion factor and the second offset expansion factor are used to determine the number of used REs for any item of the second information for the non-full-duplex area and the full-duplex area. This indication method is simple.

[0155] The following is a clear and complete description of the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this application.

[0156] References to "one embodiment" or "some embodiments" in this application mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0157] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is merely a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "plurality" means two or more. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items 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, b, and c. Among them, a, b, and c can be single or multiple.

[0158] It is understood that in this application, "indication" can include direct indication, indirect indication, explicit indication, and implicit indication. When describing that a certain indication information is used to indicate A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0159] In this application, the information indicated by the indication information is referred to as the information to be indicated. In the specific implementation process, there are many ways to indicate the information to be indicated, such as but not limited to, the information to be indicated can be directly indicated, such as the information to be indicated itself or the index of the information to be indicated, etc., or the information to be indicated can be indirectly indicated by indicating other information, wherein there is an association between the other information and the information to be indicated. It is also possible to indicate only a part of the information to be indicated, while the other parts of the information to be indicated are known or agreed in advance. For example, the indication of specific information can also be achieved with the help of the arrangement order of each information agreed in advance (such as specified in the protocol), thereby reducing the indication overhead to a certain extent.

[0160] The information to be indicated can be sent as a whole or divided into multiple sub-information and sent separately. The transmission period and / or transmission timing of these sub-information can be the same or different. The specific transmission method is not limited in this application. The transmission period and / or transmission timing of these sub-information can be predefined, for example, according to a protocol, or can be configured by the transmitting device through sending configuration information to the receiving device.

[0161] It can be understood that "sending" and "receiving" in this application indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information is XX, which can include direct sending through the air interface, and also include indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information is YY, which can include direct receiving from YY through the air interface, and also include indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0162] In other words, sending and receiving can be performed between devices, for example, between a network device and a terminal device, or can be performed within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, wiring or interface.

[0163] It is understandable that information may be processed between the source and destination of information transmission, such as coding, modulation, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated.

[0164] The communication method provided in the embodiment of the present application can be applied to cellular communication systems related to the third generation partnership project (3GPP), for example, fourth generation (4G) communication systems, such as long term evolution (LTE) communication systems, and can also be applied to fifth generation (5G) communication systems, such as 5G new radio (NR) communication systems, or to various future communication systems, such as sixth generation (6G) communication systems. The method provided in the embodiment of the present application can also be applied to Bluetooth systems, wireless fidelity (WiFi) systems, LoRa systems or Internet of Vehicles systems, communication systems that support the integration of multiple wireless technologies, and device-to-device (D2D) systems. The method provided in the embodiment of the present application can also be applied to satellite communication systems, wherein the satellite communication system can be integrated with the above-mentioned communication system. The wireless communication systems involved in this application also include but are not limited to: narrowband Internet of Things (NB-IoT) system, global system for mobile communications (GSM), enhanced data rate for GSM evolution (EDGE), wideband code division multiple access (WCDMA), code division multiple access 2000 (CDMA2000), or time division-synchronization code division multiple access (TD-SCDMA).

Communication system 100 includes a network device 101 and a terminal device 102. It should be understood that the communication system 100 to which the methods of the embodiments of the present application can be applied can include more or fewer network devices or terminal devices. Network devices and terminal devices can be hardware, functionally divided software, or a combination of the two. Network devices and terminal devices can communicate with each other through other devices or network elements. In this system, network device 101 can transmit data with multiple terminal devices, i.e., network device 101 sends downlink data to terminal device 102. Of course, terminal device 102 can also send uplink data to network device 101. Of course, data can also be transmitted between terminal devices. The apparatus provided in the embodiments of the present application can be applied to network device 101 or terminal device 102.

[0171] The satellites mentioned in the above-mentioned communication system can communicate wirelessly with terminal devices through broadcast communication signals and navigation signals, and the satellites can communicate wirelessly with ground station equipment. The satellites mentioned in the embodiments of the present application can be satellite base stations, and can also include orbital receivers or repeaters for relaying information, or network-side equipment carried on satellites. Satellites can also be divided into transparent satellites and non-transparent satellites. Transparent transmission is also called bent-pipe forwarding transmission: that is, the signal only undergoes frequency conversion, signal amplification and other processes on the satellite, and the satellite is transparent to the signal, as if it does not exist. Non-transparent transmission is also called regeneration (on-board access / processing) transmission: that is, the satellite has some or all base station functions. In addition, the satellite can work in three working modes, namely earth-fixed mode, quasi earth-fixed mode or earth-moving mode. The satellites in this application can be LEO satellites, medium orbit earth satellites (MEO) or geostationary orbit earth satellites (GEO), drones, hot air balloons, etc., and the embodiments of this application are not limited. The satellite in this application may refer to a non-ground base station or non-ground equipment, etc., and the embodiments of this application are not limited thereto.

[0172] The terminal device mentioned in the above-mentioned communication system, which can also be referred to as user equipment (UE), mobile station (MS), mobile terminal (MT), etc., is a device that provides voice or data connectivity to users. Specifically, it includes a device that provides voice to users, a device that provides data connectivity to users, or a device that provides voice and data connectivity to users. For example, it may include a handheld device with wireless connection capabilities, or a processing device connected to a wireless modem. The terminal device can communicate with the core network via the radio access network (RAN), exchange voice or data with the RAN, or exchange voice and data with the RAN. Currently, terminal devices may include: mobile phones, tablet computers, laptop computers, PDAs, mobile internet devices (MIDs), wearable devices (such as smart watches, smart bracelets, pedometers, etc.), in-vehicle devices (such as cars, bicycles, electric vehicles, airplanes, ships, trains, high-speed trains, etc.), VR devices, augmented reality (AR) devices, wireless terminals in industrial control, smart home devices (such as refrigerators, televisions, air conditioners, electric meters, etc.), intelligent robots, workshop equipment, wireless terminals in unmanned driving, wireless terminals in remote surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, and flying devices (such as intelligent robots, hot air balloons, drones, airplanes). Terminal devices may also be other devices with terminal functions, for example, a terminal device may also be a device that functions as a terminal in D2D communication.The terminal device may also include vehicle to everything (V2X) terminal equipment, machine-to-machine / machine-type communications (M2M / MTC) terminal equipment, Internet of Things (IoT) terminal equipment, light terminal equipment (light UE), reduced capability UE (REDCAP UE), subscriber unit, subscriber station, mobile station, remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, or user equipment (user device), drone equipment, etc. For example, it may include a mobile phone (or so-called "cellular" phone), a computer with a mobile terminal device, a portable, pocket-sized, handheld, or computer-built-in mobile device, etc. For example, personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), and other devices. Also included are limited devices, such as devices with low power consumption, or devices with limited storage capacity, or devices with limited computing power. Examples include information sensing devices such as barcodes, radio frequency identification (RFID), sensors, global positioning systems (GPS), and laser scanners. In this application, terminal devices with wireless transceiver capabilities and chips that can be provided in the aforementioned terminal devices are collectively referred to as terminal devices.

[0173] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with integrated circuits, or a chip, module or control unit in the device or apparatus shown above, and this application does not limit this specifically.

[0174] The network equipment mentioned in the above communication system is a device deployed in a radio access network to provide wireless communication functions for terminal devices. The network equipment can also be called an access network (RAN) entity, access node, network node, or communication device.

[0175] Specifically, the network device may be an access network device of a cellular system related to the 3rd Generation Partnership Project (3GPP). For example, a fourth-generation (4G) mobile communication system or a 5G mobile communication system. The network device may also be an access network device in an open access network (O-RAN or ORAN) or a cloud radio access network (CRAN). Alternatively, the network device may be an access network device in a communication system obtained by integrating two or more of the above communication systems.

[0176] The network equipment includes, but is not limited to, evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved NodeB, or home Node B, HNB), baseband unit (BBU), access point (AP) in wireless fidelity (WIFI) system, macro base station, micro base station, wireless relay node, donor node, wireless controller in CRAN scenario, wireless backhaul node, transmission point (TP) or transmission and receiving point (TRP). The network equipment can also be an access network equipment in a 5G mobile communication system. For example, a next generation NodeB (gNB) in a new radio (NR) system, a TRP, a TP, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system. Alternatively, the network device may also be a network node constituting a gNB or a transmission point. For example, a centralized unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). The CU and DU may be configured separately or included in the same network element. For example, a BBU. The RU may be included in a radio frequency device or radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the network device may also be a server, a wearable device, a vehicle, or an on-board device. For example, in V2X technology, the network device may be a road side unit (RSU).

[0177] It should be noted that in different systems, CU (or CU-CP and CU-UP), DU or RU may have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called an open centralized unit (O-CU) or an open CU, DU may also be called an open distributed unit (O-DU), a centralized unit control plane (CU-CP) may also be called an open centralized unit control plane (O-CU-CP) or an open CU-CP, a centralized unit user plane (CU-UP) may also be called an open centralized unit user plane (O-CU-UP) or an open CU-UP, and RU may also be called an open radio unit (O-RU). This application does not limit this. Any of the CU, CU-CP, CU-UP, DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0178] In some deployments, the CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU implements the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers, while the DU implements the functions of the radio link control (RLC), media access control (MAC), and physical (PHY) layers. Because RRC layer information ultimately becomes PHY layer information, or is converted from PHY layer information, in this architecture, higher-layer signaling, such as RRC layer signaling or PDCP layer signaling, can also be considered to be sent by the DU, or by the DU+RU. It is understood that a network device can be a CU node, a DU node, or a device that includes both a CU node and a DU node. Furthermore, the CU can be classified as a network device in the access network (RAN) or a network device in the core network (CN), without limitation here.

[0179] Optionally, the network device may also be a core network device. The core network device is responsible for access control, registration management, service management, mobility management, etc. for terminal devices accessing the network. For example, the core network device is an AMF.

[0180] It should be noted that the network device can be the device or apparatus shown above, or it can be a component (for example, a chip), module, or unit in the device or apparatus shown above, and this application does not limit it specifically.

[0181] First, some terms in this application are explained to facilitate understanding by those skilled in the art.

[0182] 1) The International Telecommunication Union (ITU) has defined three major application scenarios for 5G and future mobile communication systems: enhanced mobile broadband (eMBB), ultra reliable and low latency communications (URLLC), and massive machine type communications (mMTC).

[0183] Typical eMBB services include ultra-high-definition video, augmented reality (AR), and virtual reality (VR). The main characteristics of these services are large data transmission volumes and high transmission rates.

[0184] Typical URLLC services include wireless control in industrial manufacturing or production processes, motion control of autonomous vehicles and drones, and tactile interaction applications such as remote repair and remote surgery. These services require ultra-high reliability, low latency, small amounts of transmitted data, and are bursty.

[0185] Typical mMTC services include smart grid distribution automation and smart cities. Their main characteristics are a large number of connected devices, a small amount of transmitted data, and data insensitivity to transmission latency. These mMTC terminals must meet the requirements of low cost and very long standby time.

[0186] 2) Uplink control information (UCI) includes scheduling requests (SR), hybrid automatic repeat request acknowledgement (HARQ-ACK), and channel state information (CSI). CSI can be divided into two parts: CSI part 1 and CSI part 2. The encoded UCI bits are multiplexed onto the physical uplink shared channel (PUSCH) for transmission and must meet the following rules:

[0187] Rule 1: The coded UCI bits are only transmitted on orthogonal frequency division multiplexing (OFDM) symbols where the demodulation reference signal (DMRS) is not transmitted.

[0188] Rule 2: The encoded HARQ-ACK bits are transmitted starting from the first OFDM symbol after the first DMRS, and the encoded CSI-Part 1 bits and the encoded CSI-Part 2 bits are transmitted on the first OFDM symbol without DMRS.

[0189] Rule 3: The mapping of coded UCI bits to resource elements (REs) depends on the number of REs available for transmitting the coded UCI bits and the number of REs available for transmitting the UCI. For example, if the number of REs required for the coded UCI bits in a certain OFDM symbol exceeds half of the number of REs available for transmitting the UCI in that OFDM symbol, the coded UCI bits are mapped continuously to the REs. Otherwise, the coded UCI bits are mapped evenly and distributed to the REs of that OFDM symbol to achieve diversity gain.

[0190] The multiplexing process of UCI and PUSCH mainly includes the following steps:

[0191] Step 1: When the number of HARQ-ACK information bits is less than or equal to 2, find the positions reserved for the encoded HARQ-ACK bits.

[0192] Step 2: When the number of HARQ-ACK information bits is greater than 2, map the encoded HARQ-ACK bits.

[0193] Step 3: Map the encoded CSI-part1 bits and CSI-part2 bits.

[0194] Step 4: Map the encoded uplink data information bits.

[0195] Step 5: When the number of HARQ-ACK information bits is less than or equal to 2, map the encoded HARQ-ACK bits.

[0196] Step 6: Form a codeword (CW).

[0197] It should be understood that the mapping in this application can also be called multiplexing, and the mapping method can also be called a multiplexing method. This application does not impose any restrictions on the naming.

[0198] Among them, the rules satisfied by the above-mentioned encoded UCI bit mapping when transmitted on PUSCH are based on the half-duplex area, that is, when only the half-duplex area exists, the encoded UCI bit mapping is transmitted on PUSCH. When both the full-duplex area and the half-duplex area exist, please refer to Figure 7. Figure 7 is a partial schematic diagram of a frame structure provided by an embodiment of the present application, which includes a full-duplex area and a non-full-duplex area. For example, in-band full-duplex (bandwidth part-full duplex, BWP-FD) can support full-duplex in any sub-band, that is, simultaneous transmission and reception are achieved in the same frequency band. Some sub-bands in BWP-FD are full-duplex (full duplex, FD) areas, and some sub-bands are non-full duplex (non-FD) areas, where non-full duplex can also be called half-duplex. The full-duplex area indicates an area that can be transmitted both uplink and downlink, and the half-duplex area indicates an area that can only be transmitted uplink or downlink. Compared with subband full duplex (SBFD), BWP-FD can increase uplink bandwidth without losing downlink bandwidth. It can also flexibly match service requirements and latency requirements by adjusting the duplex mode according to service needs.

[0199] It should be understood that the present application is not limited to the BWP-FD scenario, and can be applied to any scenario that includes full-duplex and half-duplex in a certain time period.

[0200] In a low-latency, high-reliability scenario, such as URLLC communication, in order to quickly transmit a data packet, such as a URLLC data packet, as shown in FIG8 , the data packet, such as the encoded UCI bit / PUSCH in the figure, may be mapped simultaneously in a full-duplex area and a non-full-duplex area. When both full-duplex and half-duplex areas exist, how to map the control information on the data channel for transmission is a technical problem being solved by people in this field. To solve the above problems, the embodiments of the present application propose the following solutions.

[0201] With reference to the communication systems shown in Figures 1-6, when the method described in the embodiment of the present application is applied to the communication system shown in Figure 1, the first device may be a terminal device and the second device may be a network device. When the method described in the embodiment of the present application is applied to the communication system shown in Figure 2, the first device may be a terminal device and the second device may be a satellite. When the method described in the embodiment of the present application is applied to the communication system shown in Figure 3, the first device may be a network device and the second device may be a satellite. When the method described in the embodiment of the present application is applied to the communication system shown in Figure 4, the first device may be satellite 402 and the second device may be satellite 401. When the method described in the embodiment of the present application is applied to the communication system shown in Figure 5, the first device may be terminal device 502 and the second device may be terminal device 501. When the method described in the embodiment of the present application is applied to the communication system shown in Figure 6, the first device may be IAB node 602 and the second device may be IAB parent node 601. Alternatively, the first device may be terminal device 603 and the second device may be IAB node 602. It should be understood that the present application does not limit the first and second devices. The communication methods provided in the embodiments of the present application are described in detail below.

[0202] Please refer to FIG9 , which is a schematic diagram of a communication method provided in an embodiment of the present application. The method includes but is not limited to the following steps:

[0203] Step S901: The first device determines a data channel including a full-duplex area and a non-full-duplex area.

[0204] A full-duplex area refers to an area that supports both uplink and downlink transmission. A non-full-duplex area, also known as a half-duplex area, represents an area that supports both uplink and downlink transmission. In one possible implementation, the full-duplex area includes a sub-band full-duplex (SBFD) area.

[0205] Optionally, the data channel may be a PUSCH.

[0206] Optionally, the frequency band occupied by the data channel may be a first frequency band, the first frequency band including a first bandwidth part (BWP) and a second BWP, optionally, the first BWP corresponds to a full-duplex area, and the second BWP corresponds to a non-full-duplex area.

[0207] Optionally, the frequency band occupied by the data channel may be a first frequency band, the first frequency band including a first BWP, a second BWP, and a third BWP. Optionally, the first BWP corresponds to a non-full-duplex area, the second BWP corresponds to a full-duplex area, and the third BWP corresponds to a non-full-duplex area. Optionally, the data channel may include both half-duplex and full-duplex at any time within the first period of time, and only include half-duplex within the second period of time.

[0208] Optionally, the data channel may include half-duplex and full-duplex at any time within the first period of time, and only include full-duplex within the second period of time.

[0209] Optionally, the data channel may include half-duplex and full-duplex at any time within the first period of time.

[0210] The first time period and the second time period are both less than or equal to the time period of the data channel. The first time period and the second time period do not intersect, that is, the first time period and the second time period do not overlap in time and have no sequential relationship.

[0211] Step S902: The first device multiplexes the control information and data information into the data channel according to the mapping rule.

[0212] Multiplexing the control information to the data channel according to the mapping rule can be understood as mapping the control information and the data information to the REs of the data channel according to the mapping rule.

[0213] Optionally, the control information may be UCI, the data information may be uplink data information, and the data channel may be PUSCH. Multiplexing the control information and data information into the data channel according to the mapping rules may be understood as multiplexing the encoded UCI bits and the encoded uplink data information into PUSCH according to the mapping rules.

[0214] In one possible implementation, the control information may include first information and second information. The first information may include one or more of the following: HARQ-ACK or CSI-part 1; the second information may include one or more of the following: HARQ-ACK, CSI-part 1, or CSI-part 2. The first information and the second information are disjoint, that is, the intersection between the first information and the second information is empty.

[0215] In one possible implementation, the mapping rules include: the starting position of the resource mapping carrying HARQ-ACK is determined based on the starting position of the resource carrying DMRS, that is, the starting position of the resource mapping carrying HARQ-ACK is determined based on the starting position of the resource carrying DMRS. It can be understood that the starting position of the resource mapping carrying HARQ-ACK is determined based on the starting position of the resource carrying DMRS in the data channel. Optionally, the resource starting position of the DMRS may refer to the resource starting position of the DMRS in the data channel, for example, it may be the resource starting position of the DMRS in the PUSCH.

[0216] Specifically, it may mean that the resources carrying HARQ-ACK are mapped starting from the first OFDM symbol after the first DMRS; or the resources carrying HARQ-ACK are mapped on the first OFDM symbol containing DMRS; or the resources carrying HARQ-ACK are mapped starting from the first OFDM symbol before the first DMRS.

[0217] Optionally, the first OFDM symbol after the first DMRS may refer to the first symbol after the first DMRS in the data channel, for example, the first symbol after the first DMRS on the PUSCH. Accordingly, the mapping of the resources carrying HARQ-ACK starting from the first OFDM symbol after the first DMRS can be understood as the mapping of the resources carrying HARQ-ACK starting from the first OFDM symbol after the first DMRS in the data channel. Optionally, the first OFDM symbol containing DMRS may refer to the first OFDM symbol containing DMRS in the data channel, for example, the first OFDM symbol containing DMRS on the PUSCH. Accordingly, the mapping of the resources carrying HARQ-ACK on the first OFDM symbol containing DMRS may refer to the mapping of the resources carrying HARQ-ACK on the first OFDM symbol containing DMRS in the data channel. Optionally, the first OFDM symbol before the first DMRS may refer to the first OFDM symbol before the first DMRS in the data channel, for example, the first OFDM symbol before the first DMRS on the PUSCH. Accordingly, mapping the resources carrying HARQ-ACK from the first OFDM symbol before the first DMRS may refer to mapping the resources carrying HARQ-ACK from the first OFDM symbol before the first DMRS in the data channel.

[0218] Optionally, mapping the resources carrying HARQ-ACK starting from the OFDM symbol after the first DMRS can be understood as multiplexing HARQ-ACK on the RE of the data channel starting from the OFDM symbol after the first DMRS, or it can be understood as the starting position of the resource mapping carrying HARQ-ACK is the position of the OFDM symbol after the first DMRS. Mapping the resources carrying HARQ-ACK on the first OFDM symbol containing DMRS can be understood as multiplexing HARQ-ACK on the RE of the data channel starting from the first OFDM symbol containing DMRS, or it can be understood as the starting position of the resource mapping carrying HARQ-ACK is the first OFDM symbol containing DMRS. Mapping the resources carrying HARQ-ACK starting from the first OFDM symbol before the first DMRS can be understood as multiplexing HARQ-ACK on the RE of the data channel starting from the first OFDM symbol before the first DMRS, or it can be understood as the starting position of the resource mapping carrying HARQ-ACK is the first OFDM symbol before the first DMRS.

[0219] A possible implementation method is to multiplex control information and data information into a data channel according to a mapping rule, including one or more of the following: multiplexing the first information into a non-full-duplex area according to the mapping rule, multiplexing the second information into the non-full-duplex area and the full-duplex area according to the mapping rule, multiplexing part or all of the data information into the non-full-duplex area according to the mapping rule, or multiplexing part or all of the data information into the non-full-duplex area and the full-duplex area according to the mapping rule.

[0220] That is, it can be understood that multiplexing the control information to the data channel according to the mapping rule includes one or more of the following: multiplexing the HARQ-ACK or CSI-part1 in the first information to the non-full-duplex area according to the mapping rule, and / or multiplexing the HARQ-ACK, CSI-part1, or CSI-part2 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule. That is, multiplexing the encoded HARQ-ACK bit or the encoded CSI-part1 bit in the first information to the non-full-duplex area according to the mapping rule, and / or multiplexing the encoded HARQ-ACK bit, the encoded CSI-part1 bit, or the encoded CSI-part2 bit in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule.

[0221] The following is mainly described in two aspects. The first aspect is: multiplexing the HARQ-ACK or CSI-part1 in the first information to the non-full-duplex area according to the mapping rule, that is, multiplexing the encoded HARQ-ACK bit or the encoded CSI-part1 bit in the first information to the non-full-duplex area according to the mapping rule; the second aspect is: multiplexing the HARQ-ACK, CSI-part1, or CSI-part2 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, that is, multiplexing the encoded HARQ-ACK bit, the encoded CSI-part1 bit, or the encoded CSI-part2 bit in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, specifically as follows:

[0222] First aspect: multiplexing the HARQ-ACK or CSI-part1 in the first information to the non-full-duplex area according to the mapping rule, that is, multiplexing the encoded HARQ-ACK bit or the encoded CSI-part1 bit in the first information to the non-full-duplex area according to the mapping rule.

[0223] In one possible implementation, the encoded HARQ-ACK bit or the encoded CSI-part1 bit may be preferentially mapped to the non-full-duplex area according to the mapping rule, and the mapping rule may include the following: when the number of REs used for HARQ-ACK or CSI-part1 in the first information in one symbol is less than or equal to half of the number of available REs in the non-full-duplex area, the HARQ-ACK or CSI-part1 in the first information is uniformly mapped to the available REs in the non-full-duplex area; when the number of REs used for HARQ-ACK or CSI-part1 in the first information in one symbol is greater than half of the number of available REs in the non-full-duplex area, the HARQ-ACK or CSI-part1 in the first information is continuously mapped to the available REs in the non-full-duplex area. That is, it can be understood that the mapping rules may include the following: when the number of REs used by the encoded HARQ-ACK bit or the encoded CSI-part1 bit in the first information in a symbol is less than or equal to half of the number of available REs in the non-full-duplex area, the encoded HARQ-ACK bit or the encoded CSI-part1 bit in the first information is uniformly mapped on the available REs in the non-full-duplex area; when the number of REs used by the encoded HARQ-ACK bit or the encoded CSI-part1 bit in the first information in a symbol is greater than half of the number of available REs in the non-full-duplex area, the encoded HARQ-ACK bit or the encoded CSI-part1 bit in the first information is continuously mapped on the available REs in the non-full-duplex area.

[0224] Uniform mapping means that some uniformly distributed REs in the non-full-duplex area are used to place the encoded HARQ-ACK bits or the encoded CSI-part1 bits. In other words, an RE carrying HARQ-ACK or CSI-part1 is placed every L REs, where L is a positive integer greater than 0. Continuous mapping means that some continuous available REs in the non-full-duplex area are used to place REs carrying HARQ-ACK or CSI-part1.

[0225] Next, in the first aspect, two cases are described: Case 1: The HARQ-ACK in the first information is multiplexed to the non-full-duplex area according to the mapping rule, that is, the encoded HARQ-ACK bit in the first information is multiplexed to the non-full-duplex area according to the mapping rule; Case 2: The CSI-part1 in the first information is multiplexed to the non-full-duplex area according to the mapping rule, that is, the encoded CSI-part1 bit in the first information is multiplexed to the non-full-duplex area according to the mapping rule, which is described in detail as follows:

[0226] Case 1: A possible implementation method is to multiplex the HARQ-ACK in the first information into the non-full-duplex area according to the mapping rule. That is, the encoded HARQ-ACK bits in the first information are multiplexed into the non-full-duplex area according to the mapping rule. Specifically, there are two methods, namely, method A and method B:

[0227] Method A: The encoded HARQ-ACK bits are mapped starting from the first OFDM symbol after the first DMRS, that is, the resources carrying HARQ-ACK are mapped starting from the first OFDM symbol after the first DMRS.

[0228] When the number of HARQ-ACK information bits is less than or equal to 2, the encoded HARQ-ACK bits are mapped to predefined REs in the non-full-duplex area;

[0229] When the number of HARQ-ACK information bits is greater than 2, and the number of REs used for the encoded HARQ-ACK bits in a symbol is less than or equal to half of the number of available REs in the non-full-duplex area, the encoded HARQ-ACK bits are evenly mapped on the available REs in the non-full-duplex area; optionally, the available REs in the non-full-duplex area may refer to all REs in the non-full-duplex area in a symbol of the data channel excluding the used REs, such as the REs used by DMRS.

[0230] When the number of HARQ-ACK information bits is greater than 2, and the number of REs used for the encoded HARQ-ACK bits in a symbol is greater than half of the number of available REs in the non-full-duplex area, the encoded HARQ-ACK bits are continuously mapped to the available REs in the non-full-duplex area. Optionally, the available REs in the non-full-duplex area may refer to all REs in the non-full-duplex area in a symbol of the data channel excluding the used REs, such as the REs used by the DMRS.

[0231] Optionally, when the number of HARQ-ACK information bits is less than or equal to 2, the encoded HARQ-ACK bits can be mapped to available REs in a non-full-duplex area based on a puncture mapping rule, and mapped after mapping the encoded uplink data bits. When the number of HARQ-ACK information bits is greater than 2, the encoded HARQ-ACK bits can be mapped to available REs in a non-full-duplex area based on a rate matching mapping rule, and mapped before mapping the encoded CSI-part1 bits.

[0232] In one example, refer to Figure 10, which is a schematic diagram of uniform mapping of encoded HARQ-ACK bits proposed in an embodiment of the present application. As can be seen from the figure, there are full-duplex areas and non-full-duplex areas in the data channel. Assuming that the number of information bits of HARQ-ACK is greater than 2, assuming that the number of encoded HARQ-ACK bits is equal to 8, assuming that quadrature phase shift keying (QPSK) modulation is used, then the number of REs carrying HARQ-ACK is determined to be 4, and the encoded HARQ-ACK bit is mapped from the first OFDM symbol after the first DMRS, that is, the third OFDM symbol in Figure 10 is mapped. The number of REs used for the encoded HARQ-ACK bit in one symbol is 4, and the number of available REs in the non-full-duplex area in the third OFDM symbol is 8, that is, the available REs are all REs in the non-full-duplex area in the third OFDM symbol in the data channel, excluding the used REs, for example, excluding the REs used by the DMRS, wherein the number of all REs in the non-full-duplex area in the third OFDM symbol is is 8, the number of REs used by the DMRS in the non-full-duplex area in the third OFDM symbol is 0, therefore, the number of available REs is 8, and half of the number of available REs in the non-full-duplex area in the third OFDM symbol is 4 (8 / 2=4), and the number of REs used for the encoded HARQ-ACK bits in one symbol is equal to half of the number of available REs in the non-full-duplex area, that is, 4 is equal to 4, therefore, as shown in the figure, the encoded HARQ-ACK bits are mapped starting from the first OFDM symbol after the first DMRS, that is, mapping starts from the third OFDM symbol, and the encoded HARQ-ACK bits are evenly mapped on the available REs in the non-full-duplex area.

[0233] It should be noted that in the above exemplary Figure 10 and the following Figures 11 to 14, the number of used REs only counts the REs shown in the figures. This is for illustration only, and the number of REs actually used should comply with the definition and should depend on the specific circumstances.

[0234] In the above method, the reliability of HARQ-ACK feedback can be guaranteed through method A.

[0235] In an example, please refer to Figure 11, which is a schematic diagram of a continuous mapping of encoded HARQ-ACK bits proposed in an embodiment of the present application. It can be seen from the figure that there are full-duplex areas and non-full-duplex areas in the data channel. Assuming that the number of information bits of HARQ-ACK is greater than 2, when the number of encoded HARQ-ACK bits is equal to 12, assuming that QPSK modulation is used, then the number of REs carrying HARQ-ACK is determined to be 6, and the encoded HARQ-ACK bits are mapped from the first OFDM symbol after the first DMRS, that is, the mapping starts from the third OFDM symbol in Figure 11, the number of REs used for the encoded HARQ-ACK bits in one symbol is 6, and the number of available REs in the non-full-duplex area in the third OFDM symbol is 8, that is, the available REs are all in the non-full-duplex area in the third OFDM symbol in the data channel. Some REs remove used REs, such as REs used by DMRS, wherein the number of all REs in the non-full-duplex area in the third OFDM symbol is 8, and the number of REs used by DMRS in the non-full-duplex area in the third OFDM symbol is 0. Therefore, the number of available REs in the non-full-duplex area is 8, and half of the number of available REs in the non-full-duplex area in the third OFDM symbol is 4 (i.e., 8 / 2=4). The number of REs used for the encoded HARQ-ACK bits in one symbol is greater than half of the number of available REs in the non-full-duplex area, i.e., 6 is greater than 4. Therefore, as shown in the figure, the encoded HARQ-ACK bit is mapped starting from the first OFDM symbol after the first DMRS, i.e., mapping starts from the third OFDM symbol, and the encoded HARQ-ACK bit is continuously mapped on the available REs in the non-full-duplex area.

[0236] Mode B: The encoded HARQ-ACK bits are mapped on the first OFDM symbol containing DMRS, that is, the resources carrying HARQ-ACK are mapped on the first OFDM symbol containing DMRS.

[0237] When the number of HARQ-ACK information bits is less than or equal to 2, the encoded HARQ-ACK bits are mapped to predefined REs in the non-full-duplex area;

[0238] When the number of HARQ-ACK information bits is greater than 2, and the number of REs used by the encoded HARQ-ACK in one symbol is less than or equal to half of the number of available REs in the non-full-duplex area, the encoded HARQ-ACK bits are uniformly mapped on the available REs in the non-full-duplex area; wherein the available REs in the non-full-duplex area may refer to all REs in the non-full-duplex area in one symbol of the data channel excluding the used REs, such as the REs used by DMRS, that is, half of the number of available REs in the non-full-duplex area is half of the number of REs remaining after all REs in the non-full-duplex area in one symbol of the data channel are removed from the number of used REs, for example, excluding the REs used by DMRS;

[0239] When the number of HARQ-ACK information bits is greater than 2, and the number of REs used by the encoded HARQ-ACK bits in a symbol is greater than half of the number of available REs in the non-full-duplex area, the encoded HARQ-ACK bits are continuously mapped on the available REs in the non-full-duplex area; wherein, the available REs in the non-full-duplex area may refer to all REs in the non-full-duplex area in a symbol of the data channel excluding the used REs, such as the REs used by DMRS, that is, half of the number of available REs in the non-full-duplex area is half of the number of REs remaining after all REs in the non-full-duplex area in a symbol of the data channel excluding the number of used REs, for example, excluding the REs used by DMRS.

[0240] Optionally, when the number of HARQ-ACK information bits is less than or equal to 2, the encoded HARQ-ACK bits can be mapped to available REs in the non-full-duplex area based on the puncturing mapping rule, and mapped after mapping the encoded uplink data information bits. When the number of HARQ-ACK information bits is greater than 2, the encoded HARQ-ACK bits can be mapped to available REs in the non-full-duplex area based on the rate matching mapping rule, and mapped before mapping the encoded CSI-part1 bits.

[0241] In one example, please refer to Figure 12, which is a schematic diagram of another uniform mapping of the encoded HARQ-ACK bits proposed in an embodiment of the present application. It can be seen from the figure that there are full-duplex areas and non-full-duplex areas in the data channel. Assuming that the number of information bits of HARQ-ACK is greater than 2, assuming that when the number of encoded HARQ-ACK bits is equal to 4, assuming that QPSK modulation is used, then the number of REs carrying HARQ-ACK is determined to be 2, and the encoded HARQ-ACK bits are mapped on the first OFDM symbol containing DMRS, that is, on the second OFDM symbol in Figure 12, the number of REs used for the encoded HARQ-ACK bits in one symbol is 2, and the available REs in the non-full-duplex area are 2. Half of the number of REs is the number of REs in the non-full-duplex area in the second OFDM symbol in the data channel minus the used REs, for example, half of the number of REs remaining after the number of REs used by DMRS, that is, (8-3) / 2=2.5, wherein the number of REs in the non-full-duplex area in the second OFDM symbol is 8, and the number of REs used by DMRS in the non-full-duplex area in the second OFDM symbol is 3. Since 2<2.5, as shown in the figure, the encoded HARQ-ACK bits are mapped on the first OFDM symbol containing DMRS, that is, the second OFDM symbol, and the encoded HARQ-ACK bits are evenly mapped on the available REs in the non-full-duplex area.

[0242] In the above method, method B can ensure the reliability of HARQ-ACK feedback while quickly transmitting feedback information.

[0243] In another example, please refer to Figure 13, which is a schematic diagram of uniform mapping and continuous mapping of encoded HARQ-ACK bits proposed in an embodiment of the present application. It can be seen from the figure that there are full-duplex areas and non-full-duplex areas in the data channel. Assuming that the number of information bits of HARQ-ACK is greater than 2, assuming that when the number of encoded HARQ-ACK bits is equal to 12, assuming that QPSK modulation is used, then the number of REs carrying HARQ-ACK is determined to be 6, and the encoded HARQ-ACK bits are mapped on the first OFDM symbol containing DMRS, that is, the number of REs carrying HARQ-ACK on the second OFDM symbol in Figure 13 is 6, where the non-full-duplex area in the second OFDM symbol is 6. The number of REs in the domain is 8, the number of DMRS REs in the non-full-duplex area in the second OFDM symbol is 4, and half of the number of available REs in the non-full-duplex area is the number of REs in the non-full-duplex area in the second OFDM symbol in the data channel. After removing the used REs, for example, half of the number of REs remaining after the number of REs used by DMRS is 2, that is, (8-4) / 2=2. Since the number of REs used for the encoded HARQ-ACK bits in one symbol is 4>2, as shown in the figure, the encoded HARQ-ACK bits are mapped on the first OFDM symbol containing DMRS, that is, the second OFDM symbol, and the encoded HARQ-ACK bits are continuously mapped on the first packet. On the available REs of the non-full-duplex area of ​​the OFDM symbol containing DMRS, that is, continuously mapped on the available REs of the non-full-duplex area of ​​the second OFDM symbol, a total of 4 REs are continuously mapped. Since the number of REs carrying HARQ-ACK is 6, a total of 4 REs are continuously mapped. The number of REs used for the remaining encoded HARQ-ACK bits is 2 (i.e., 6-4=2). At this time, the remaining encoded HARQ-ACK bits are mapped starting from the first OFDM symbol after the DMRS symbol, that is, on the third OFDM symbol in Figure 13, the number of REs used for the encoded HARQ-ACK bits in one symbol is 2, and half of the number of available REs in the non-full-duplex area is 4 (i.e., 8 / 2 =4), wherein the available REs are all REs in the non-full-duplex area in the third OFDM symbol in the data channel excluding the used REs, such as the number of REs remaining after the REs used by the DMRS. The number of all REs in the non-full-duplex area in the third OFDM symbol is 8, and the number of REs used by the DMRS in the non-full-duplex area in the third OFDM symbol is 0. Therefore, the number of available REs in the non-full-duplex area in the third OFDM symbol is 8. Since 2<4, as shown in the figure, the remaining encoded HARQ-ACK bits are mapped to the first OFDM symbol after the first DMRS, that is, the third OFDM symbol, and are evenly mapped to the available REs in the non-full-duplex area.

[0244] Case 2: A possible implementation is to multiplex the CSI-part 1 in the first information into the non-full-duplex area according to a mapping rule. That is, the encoded CSI-part 1 bits in the first information are multiplexed into the non-full-duplex area according to the mapping rule. Specifically, the following is achieved:

[0245] Optionally, the coded CSI-part1 bits may be mapped starting from available REs in the non-full-duplex region of the first OFDM symbol.

[0246] The mapping rule may include: when the number of REs used for the encoded CSI-part1 bits in a symbol is less than or equal to half of the number of available REs in the non-full-duplex area, the encoded CSI-part1 bits are uniformly mapped on the available REs in the non-full-duplex area; when the number of REs used for the encoded CSI-part1 bits in a symbol is greater than half of the number of available REs in the non-full-duplex area, the encoded CSI-part1 bits are continuously mapped on the available REs in the non-full-duplex area.

[0247] Optionally, when the number of HARQ-ACK information bits is less than or equal to 2, the number of available REs for the encoded CSI-part1 bit mapping may refer to the available REs in the non-full-duplex area, which may refer to all REs in the non-full-duplex area excluding used REs in a symbol of the data channel, such as REs used by DMRS.

[0248] Optionally, when the number of information bits of HARQ-ACK is greater than 2, the number of available REs for the encoded CSI-part1 bit mapping may refer to the available REs in the non-full-duplex area, which may refer to all REs in the non-full-duplex area excluding used REs in a symbol of the data channel, such as REs used by DMRS and REs used by HARQ-ACK.

[0249] In an example, please refer to Figure 14, which is a schematic diagram of a continuous mapping of encoded CSI-part1 bits proposed in an embodiment of the present application. As can be seen from the figure, there are full-duplex areas and non-full-duplex areas in the data channel. Assuming that the number of information bits of CSI-part1 is greater than 2, the number of encoded CSI-part1 bits is equal to 16. Assuming that QPSK modulation is used, the number of REs carrying CSI-part1 is determined to be 8. The encoded CSI-part1 bits are mapped from the available REs in the non-full-duplex area of ​​the first OFDM symbol, such as the first OFDM symbol in Figure 14. The number of REs carrying CSI-part1 is 8, and the number of available REs in the non-full-duplex area is 8. The number of available REs can refer to all REs in the non-full-duplex area in the first OFDM symbol in the data channel excluding used REs, such as REs used by DMRS and HA The number of REs remaining after the REs used for RQ-ACK, all REs in the non-full-duplex area in the first OFDM symbol are 8, the REs used by DMRS in the non-full-duplex area in the first OFDM symbol are 0, and the REs used by HARQ-ACK in the non-full-duplex area in the first OFDM symbol are 0. Therefore, the number of available REs is 8 (i.e., 8-0-0=8), and half of the number of available REs in the non-full-duplex area is 4, i.e., 8 / 2=4. Since the number of REs used for the encoded CSI-part1 bits in one symbol is 8>4, as shown in the figure, the encoded CSI-part1 bits are mapped starting from the available REs in the non-full-duplex area of ​​the first OFDM symbol, that is, mapping starts from the first OFDM symbol, and the encoded CSI-part1 bits are continuously mapped on the available REs in the non-full-duplex area of ​​the first OFDM symbol, for a total of 8 consecutive REs.

[0250] In the second aspect, multiplexing one or more items of the second information to the non-full-duplex area and the full-duplex area according to a mapping rule may specifically include:

[0251] Multiplexing the HARQ-ACK in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, or multiplexing the CSI-part1 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, or multiplexing the CSI-part2 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, or multiplexing the HARQ-ACK and CSI-part1 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, or multiplexing the HARQ-ACK and CSI-part2 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, or multiplexing the CSI-part1 and CSI-part2 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, or multiplexing the HARQ-ACK, CSI-part1 and CSI-part2 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule.

[0252] It should be noted that, in the present application, multiplexing the HARQ-ACK in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule means multiplexing the encoded HARQ-ACK bits in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, multiplexing the CSI-part1 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule means multiplexing the encoded CSI-part1 bits in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule, and multiplexing the CSI-part2 in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule means multiplexing the encoded CSI-part2 bits in the second information to the non-full-duplex area and the full-duplex area according to the mapping rule.

[0253] The mapping rule may include: when the number of used REs of HARQ-ACK, CSI-part1 or CSI-part2 in the second information in one symbol is less than or equal to half of the number of available REs in the full-duplex area and the non-full-duplex area, the HARQ-ACK, CSI-part1 or CSI-part2 in the second information is uniformly mapped on the available REs in the full-duplex area and the non-full-duplex area; when the number of used REs of HARQ-ACK, CSI-part1 or CSI-Part2 in the second information in one symbol is greater than half of the number of available REs in the full-duplex area and the non-full-duplex area, the HARQ-ACK, CSI-part1 or CSI-part2 in the second information is continuously mapped on the available REs in the full-duplex area and the non-full-duplex area.

[0254] That is, it can be understood that the mapping rule may include: when the number of used REs of the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-part2 bit in the second information in a symbol is less than or equal to half of the number of available REs in the full-duplex area and the non-full-duplex area, the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-part2 bit in the second information is uniformly mapped on the available REs in the full-duplex area and the non-full-duplex area; when the number of used REs of the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-part2 bit in the second information in a symbol is greater than half of the number of available REs in the full-duplex area and the non-full-duplex area, the encoded HARQ-ACK bit, the encoded CSI-part1 bit or the encoded CSI-part2 bit in the second information is continuously mapped on the available REs in the full-duplex area and the non-full-duplex area.

[0255] Among them, the coded HARQ-ACK bit, coded CSI-part1 bit or coded CSI-part2 bit in the second information is uniformly mapped on the RE in the full-duplex area and the non-full-duplex area, which can be understood as the coded HARQ-ACK bit, coded CSI-part1 bit or coded CSI-part2 bit in the second information is uniformly mapped on the RE in the available area, and the RE in the available area is the available RE in the full-duplex area and the non-full-duplex area; the coded HARQ-ACK bit, coded CSI-part1 bit or coded CSI-part2 bit in the second information is continuously mapped on the RE in the full-duplex area and the non-full-duplex area, which can be understood as the coded HARQ-ACK bit, coded CSI-part1 bit or coded CSI-part2 bit in the second information is continuously mapped on the RE in the available area, and the RE in the available area is the available RE in the full-duplex area and the non-full-duplex area.

[0256] It should be noted that in the first aspect, the HARQ-ACK or CSI-part1 in the first information is multiplexed to the non-full-duplex area according to the mapping rule, and / or in the second aspect, one or more of the second information is multiplexed to the non-full-duplex area and the full-duplex area according to the mapping rule. The description of the available REs is specifically divided into the following two cases, namely case M and case N, as follows:

[0257] Case M: When the number of HARQ-ACK information bits is less than or equal to 2,

[0258] The available REs for CSI-part1 mapping may include two situations, namely, when the first information is multiplexed into the non-full-duplex area, the available REs for CSI-part1 mapping may refer to all REs in the non-full-duplex area excluding the used REs, such as REs used by DMRS, in one symbol of the data channel; when one or more items of the second information are multiplexed into the non-full-duplex area and the full-duplex area, the available REs for CSI-part1 mapping may refer to all REs in the non-full-duplex area and the full-duplex area excluding the used REs, such as REs used by DMRS, in one symbol of the data channel.

[0259] The available REs for CSI-part2 mapping may include two situations, namely, when the first information is multiplexed into the non-full-duplex area, the available REs for CSI-part2 mapping may refer to all REs in the non-full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS and REs used by CSI-part1; when one or more items of the second information are multiplexed into the non-full-duplex area and the full-duplex area, the available REs for CSI-part2 mapping may refer to all REs in the non-full-duplex area and the full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS and REs used by CSI-part1.

[0260] The available REs for mapping uplink data information may include two situations, namely, when the first information is multiplexed into the non-full-duplex area, the available REs for mapping uplink data information may refer to all REs in the non-full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS, REs used by CSI-part1, and REs used by CSI-part2; when one or more items of the second information are multiplexed into the non-full-duplex area and the full-duplex area, the available REs for mapping uplink data information may refer to all REs in the non-full-duplex area and the full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS, REs used by CSI-part1, and REs used by CSI-part2.

[0261] Case N: When the number of HARQ-ACK information bits is greater than 2,

[0262] The available REs for HARQ-ACK mapping may include two situations, namely, when the first information is multiplexed into the non-full-duplex area, the available REs for HARQ-ACK mapping may refer to all REs in the non-full-duplex area excluding the used REs, such as REs used by DMRS, in one symbol of the data channel; when one or more items of the second information are multiplexed into the non-full-duplex area and the full-duplex area, the available REs for HARQ-ACK mapping may refer to all REs in the non-full-duplex area and the full-duplex area excluding the used REs, such as REs used by DMRS, in one symbol of the data channel.

[0263] The available REs for CSI-part1 mapping may include two situations, namely, when the first information is multiplexed into the non-full-duplex area, the available REs for CSI-part1 mapping may refer to all REs in the non-full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS and REs used by HARQ-ACK; when one or more items of the second information are multiplexed into the non-full-duplex area and the full-duplex area, the available REs for CSI-part1 mapping may refer to all REs in the non-full-duplex area and the full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS and REs used by HARQ-ACK.

[0264] The available REs for CSI-part2 mapping may include two situations, namely, when the first information is multiplexed into the non-full-duplex area, the available REs for CSI-part2 mapping may refer to all REs in the non-full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS, REs used by HARQ-ACK, and REs used by CSI-part1; when one or more items of the second information are multiplexed into the non-full-duplex area and the full-duplex area, the available REs for CSI-part2 mapping may refer to all REs in the non-full-duplex area and the full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS, REs used by HARQ-ACK, and REs used by CSI-part1.

[0265] The available REs for mapping uplink data information may include two situations, namely, when the first information is multiplexed into the non-full-duplex area, the available REs for mapping uplink data information may refer to all REs in the non-full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS, REs used by HARQ-ACK, REs used by CSI-part1, and REs used by CSI-part2; when one or more items of the second information are multiplexed into the non-full-duplex area and the full-duplex area, the available REs for mapping uplink data information may refer to all REs in the non-full-duplex area and the full-duplex area excluding the used REs in one symbol of the data channel, such as REs used by DMRS, REs used by HARQ-ACK, REs used by CSI-part1, and REs used by CSI-part2.

[0266] In one possible implementation, when one or more items of the second information are multiplexed to the non-full-duplex area and the full-duplex area according to a mapping rule, the method further includes: receiving first indication information, the first indication information being used to determine one or more of the following: the number of used REs for any item of the second information in the full-duplex area, the number of used REs for any item of the second information in the non-full-duplex area, or the number of used REs for any item of the second information across the full-duplex area and the non-full-duplex area. In this way, performance loss in the full-duplex area can be compensated and reliability of transmission of the second information can be ensured.

[0267] It should be noted that the number of used REs in any item of the second information across the full-duplex area and the non-full-duplex area in this application can be understood as the number of used REs in any item of the second information across the full-duplex area and the non-full-duplex area.

[0268] Optionally, the receiving of the first indication information may refer to the first device receiving the first indication information from the second device.

[0269] Optionally, the first indication information may be downlink control information (DCI) or configuration information of a higher-layer signaling, which is not limited in the embodiment of the present application.

[0270] Optionally, the first indication information may be carried in one or more of the following: protocol predefinition, network configuration, high-layer signaling, or physical layer signaling.

[0271] The first indication information may specifically include the following three situations: situation A, situation B, and situation C. The details are as follows:

[0272] Case A: The first indication information includes one or more of the following: a first expansion factor, a second expansion factor, or a third expansion factor. The first expansion factor is used to determine the number of REs used in any one of the second information in the full-duplex area, the second expansion factor is used to determine the number of REs used in any one of the second information in the non-full-duplex area, and the third expansion factor is used to determine the number of REs used in any one of the second information across the full-duplex area and the non-full-duplex area. Optionally, the first expansion factor corresponds to the full-duplex area, the second expansion factor corresponds to the non-full-duplex area, and the third expansion factor corresponds to the cross-full-duplex area and the non-full-duplex area. The indication method of Case A can flexibly indicate different scenario types corresponding to different expansion factors.

[0273] Optionally, the first expansion factor, the second expansion factor, or the third expansion factor may be configured by higher layer signaling.

[0274] In one example, please refer to Figure 15, which is a schematic diagram of a first indication information provided in an embodiment of the present application, wherein the first indication information includes factor 1, factor 2, and factor 3, factor 1 is used to determine the number of REs used for any item of the second information in the full-duplex area, factor 2 is used to determine the number of REs used for any item of the second information in the non-full-duplex area, and factor 3 is used to determine the number of REs used for any item of the second information across the full-duplex area and the non-full-duplex area.

[0275] In one possible implementation, different expansion factor tables may be configured by protocol predefinition, network configuration, physical layer signaling, or high-layer signaling. The different expansion factor tables correspond to different scenario types. For example, there are three expansion factor tables, namely Table 1, Table 2, and Table 3. Table 1 may include the serial number of the expansion factor and the corresponding value of the expansion factor, Table 2 may include the serial number of the expansion factor and the corresponding value of the expansion factor, and Table 3 may include the serial number of the expansion factor and the corresponding value of the expansion factor. For example, there are three different scenario types, namely scenario type 1, scenario type 2, and scenario type 3, where scenario type 1 is a full-duplex area. , scenario type 2 is a scenario of a non-full-duplex area, scenario type 3 is a scenario spanning a full-duplex area and a non-full-duplex area, Table 1 corresponds to scenario type 1, Table 2 corresponds to scenario 2, and Table 3 corresponds to scenario 3. Optionally, an indication message may be received from a second device, where the indication message is used to indicate the serial number of the expansion factor. The first device determines the value of the expansion factor based on the actually used scenario type and the indication message. For example, the first device determines that the actually used scenario type is scenario type 1. Accordingly, the first device determines Table 1 corresponding to scenario type 1, and based on the serial number of the expansion factor indicated by the indication message, determines from Table 1 the value of the expansion factor corresponding to the serial number of the expansion factor. For example, the first device determines that the actually used scenario type is scenario type 3. Accordingly, the first device determines Table 3 corresponding to scenario type 3, and based on the serial number of the expansion factor indicated by the indication message, determines from Table 3 the value of the expansion factor corresponding to the serial number of the expansion factor.

[0276] Case B: The first indication information includes a first expansion factor and / or a second expansion factor, the first expansion factor is used to determine the number of REs used in any item of the second information in the full-duplex area, the second expansion factor is used to determine the number of REs used in any item of the second information in the non-full-duplex area, the first expansion factor and the second expansion factor are used to determine a third expansion factor, and the third expansion factor is used to determine the number of REs used in any item of the second information across the full-duplex area and the non-full-duplex area. Optionally, the first indication information includes the first expansion factor and / or the second expansion factor, and the third expansion factor is determined based on the ratio of resources in the full-duplex area or the non-full-duplex area used in any item of the first indication information and the second information to the total resources used in any item of the second information. The indication method of Case B is flexible, reliable, and simple to indicate.

[0277] Optionally, the first expansion factor and the second expansion factor may be configured by higher-layer signaling.

[0278] In one example, the first indication information includes a first expansion factor and a second expansion factor, the first expansion factor is beta1, the second expansion factor is beta2, the resources of the full-duplex area or non-full-duplex area used by any item in the second information account for 1 / 2 of the total resources used by any item in the second information, and the third expansion factor beta3 = (beta1+beta2)*1 / 2.

[0279] Case C: The first indication information includes a first expansion factor, and the first indication information may further include any of the following: a first offset expansion factor or a second offset expansion factor. The first expansion factor is used to determine the number of used REs for any item of the second information for the non-full-duplex zone. The first expansion factor and the first offset expansion factor are used to determine the number of used REs for any item of the second information for the full-duplex zone. The first expansion factor and the second offset expansion factor are used to determine the number of used REs for any item of the second information for the non-full-duplex zone and the full-duplex zone. This indication method is simple.

[0280] Optionally, the first expansion factor may be an original expansion factor.

[0281] Optionally, the first expansion factor may be configured by higher layer signaling, and the first offset expansion factor and the second offset expansion factor may be configured by higher layer signaling, predefined by a protocol, or indicated by physical layer signaling.

[0282] In one example, assuming that the second information includes HARQ-ACK, the first indication information includes a first expansion factor, a first offset expansion factor, and a second offset expansion factor, wherein the first expansion factor beta=2, the first offset expansion factor pbeta1=3, and the second offset expansion factor pbeta2=2. Assuming that the number of information bits of the original HARQ-ACK is 4 bits and the number of cyclic redundancy check (CRC) bits is 2 bits,

[0283] When HARQ-ACK is in a non-full-duplex area, since the first spreading factor beta=2, the number of bits transmitted by the HARQ-ACK in the non-full-duplex area is (4+2)*2=12 bits. Assuming that QPSK modulation is used, the number of REs used for the HARQ-ACK in the non-full-duplex area is determined to be 6 REs based on the first spreading factor.

[0284] When HARQ-ACK is in the full-duplex area, since the first spreading factor beta=2 and the first offset spreading factor pbeta1=3, the number of bits transmitted by HARQ-ACK in the full-duplex area is (4+2)*(2+3)=30 bits. Assuming that QPSK modulation is used, the number of REs used for HARQ-ACK in the full-duplex area is determined to be 15 REs based on the first spreading factor and the first offset spreading factor.

[0285] When HARQ-ACK is in the non-full-duplex and full-duplex areas, since the first spreading factor beta=2 and the second offset spreading factor pbeta2=2, the number of bits of HARQ-ACK transmission in the non-full-duplex area and the full-duplex area is (4+2)*(2+2)=24 bits. Assuming that QPSK modulation is used, the number of REs used for HARQ-ACK in the non-full-duplex area and the full-duplex area is determined to be 12REs based on the first spreading factor and the second offset spreading factor.

[0286] To summarize, assuming that the second information includes HARQ-ACK, the first indication information includes a first expansion factor, a first offset expansion factor and a second offset expansion factor, wherein the first expansion factor beta=2, the first offset expansion factor pbeta1=3, and the second offset expansion factor pbeta2=2, assuming that the number of information bits of the original HARQ-ACK is 4 bits, and the number of CRC bits is 2 bits, assuming that QPSK modulation is used, the number of REs used for the HARQ-ACK in the non-full-duplex area is determined to be 6REs based on the first expansion factor; the number of REs used for the HARQ-ACK in the full-duplex area is determined to be 15REs based on the first expansion factor and the first offset expansion factor; and the number of REs used for the HARQ-ACK in the non-full-duplex area and the full-duplex area is determined to be 12REs based on the first expansion factor and the second offset expansion factor.

[0287] Optionally, the first indication information includes a first expansion factor, and the first indication information includes a first offset expansion factor. The first expansion factor is used to determine the number of REs used in any one of the second information of the non-full-duplex area. The first expansion factor and the first offset expansion factor are used to determine the number of REs used in any one of the second information of the full-duplex area. The ratio of the resources of the full-duplex or non-full-duplex area used by any one of the first expansion factor, the first offset expansion factor, and the second information to the total resources used by any one of the second information is used to determine the number of REs used in any one of the second information of the non-full-duplex area and the full-duplex area. This indication method is simple.

[0288] In another possible example, the first indication information includes a first expansion factor, and the first indication information may further include any of the following: a first offset expansion factor or a second offset expansion factor. The first expansion factor is used to determine the number of used REs for any item of the second information for the full-duplex area. The first expansion factor and the first offset expansion factor are used to determine the number of used REs for any item of the second information for the non-full-duplex area. The first expansion factor and the second offset expansion factor are used to determine the number of used REs for any item of the second information for the non-full-duplex area and the full-duplex area.

[0289] Optionally, the larger the value included in the first indication information, for example, the larger the values ​​of the first expansion factor, the second expansion factor, and the third expansion factor included in the first indication information, the more REs required to represent the UCI, and the more accurate the UCI demodulation is guaranteed, but at the same time, the fewer REs available for uplink data transmission. This can be understood as setting the code rate used for the associated UCI. A larger value indicates a lower code rate for the UCI.

[0290] Optionally, the original expansion factor can be Specifically as shown in formula (1), formula (2) and formula (3), in the prior art, the number of REs used for HARQ-ACK can be determined based on formula (1), as follows:

[0291] Among them, O ACK Refers to the information bits of HARQ-ACK, L ACK It is the CRC bit of HARQ-ACK, It refers to the number of REs used in the lth OFDM that can be used to transmit UCI, α is the parameter "scaling" specified by the high layer, K r is the size of the rth code block (CB) of the PUSCH transmission. l0 is the first OFDM symbol after the first DMRS position that does not carry DMRS.

[0292] The number of REs used for CSI-part1 is determined based on formula (2), as follows:

[0293] Among them, O CSI-1 Refers to the information bits of CSI-part1, L CSI-1 It is the CRC bit of CSI-part1. It refers to the number of REs used in the lth OFDM that can be used to transmit UCI, α is the parameter "scaling" specified by the high layer, Kr is the size of the rth code block (CB) of the PUSCH transmission. l0 is the first OFDM symbol after the first DMRS position that does not carry DMRS. Q′ ACK Indicates the number of REs used for HARQ-ACK.

[0294] The number of REs used for CSI-part2 is determined based on formula (3), as follows:

[0295] Among them, O CSI-2 Refers to the information bits of CSI-part2, L CSI-2 It is the CRC bit of CSI-part2. It refers to the number of REs used in the lth OFDM that can be used to transmit UCI, α is the parameter "scaling" specified by the high layer, K r is the size of the rth code block (CB) of the PUSCH transmission. l0 is the first OFDM symbol after the first DMRS position that does not carry DMRS. Q′ ACK Indicates the number of REs used for HARQ-ACK, Q′ CSI-1 Indicates the number of REs used in CSI-part1.

[0296] It should be noted that the process of determining one or more of the following based on the first indication information can be similar to the process of determining the number of REs used for HARQ-ACK based on formula (1), the process of determining the number of REs used for CSI-part1 based on formula (2), and the process of determining the number of REs used for CSI-part2 based on formula (3). The following one or more include: the number of REs used in any one of the second information of the full-duplex area, the number of REs used in any one of the second information of the non-full-duplex area, or the number of REs used in any one of the second information across the full-duplex area and the non-full-duplex area.

[0297] In another possible implementation, when one or more items of the second information are multiplexed to the non-full-duplex area and the full-duplex area according to a mapping rule, the method further includes: receiving second indication information, the second indication information being used to determine one or more of the following: the maximum value of the ratio between the number of REs used in any one of the second information in the full-duplex area and the number of REs used for data transmission or data channels, the maximum value of the ratio between the number of REs used in any one of the second information in the non-full-duplex area and the number of REs used for data transmission or data channels, or the maximum value of the ratio between the number of REs used in any one of the second information across the full-duplex area and the non-full-duplex area and the number of REs used for data transmission or data channels. In this way, the performance loss of the full-duplex area can be compensated and the reliability of the transmission of the second information can be guaranteed.

[0298] It should be noted that the maximum value of the ratio between the number of REs used for any item in the second information and the number of REs used for data transmission or data channels can be understood as the upper limit of the ratio of different UCIs to uplink data or PUSCH, or the upper limit of the ratio of the number of REs occupied by different UCIs to the number of REs occupied by uplink data or PUSCH.

[0299] It should be noted that the maximum value of the ratio between the number of REs used in any one of the second information across full-duplex areas and non-full-duplex areas in this application and the number of REs used for data transmission or data channels can be understood as the maximum value of the ratio between the number of REs used in any one of the second information across full-duplex areas and non-full-duplex areas and the number of REs used for data transmission or data channels.

[0300] Optionally, the receiving of the second indication information may refer to the first device receiving the second indication information from the second device.

[0301] Optionally, the second indication information may be configuration information of DCI or higher-layer signaling, which is not limited in the embodiment of the present application.

[0302] Optionally, the second indication information may be carried in one or more of the following: protocol predefinition, network configuration, high-layer signaling, or physical layer signaling.

[0303] The second indication information may specifically include the following three situations: situation D, situation E, and situation F. The details are as follows:

[0304] Case D: The second indication information includes one or more of the following: a first scaling factor, a second scaling factor, and a third scaling factor, wherein the first scaling factor is used to determine the maximum value of the ratio between the number of used REs of any item of the second information in a full-duplex area and the number of used REs for data transmission or a data channel, the second scaling factor is used to determine the maximum value of the ratio between the number of used REs of any item of the second information in a non-full-duplex area and the number of used REs for data transmission or a data channel, and the third scaling factor is used to determine the maximum value of the ratio between the number of used REs of any item of the second information across a full-duplex area and a non-full-duplex area and the number of used REs for data transmission or a data channel. Optionally, the first scaling factor corresponds to a full-duplex area, the second scaling factor corresponds to a non-full-duplex area, and the third scaling factor corresponds to a cross-full-duplex area and a non-full-duplex area.

[0305] Optionally, the first scaling factor, the second scaling factor, and the third scaling factor may be configured by higher layer signaling.

[0306] In one possible implementation, different scaling factor tables can be configured by protocol predefinition, network configuration, physical layer signaling, or high-layer signaling. The different scaling factor tables correspond to different scenario types. For details, please refer to different expansion factor tables. The different expansion factor tables correspond to different scenario types, which will not be repeated here.

[0307] Case E: The second indication information includes a first scaling factor and / or a second scaling factor, the first scaling factor being used to determine the maximum value of the ratio between the number of REs used in any one of the second information in the full-duplex area and the number of REs used for data transmission or data channels, the second scaling factor being used to determine the maximum value of the ratio between the number of REs used in any one of the second information in the non-full-duplex area and the number of REs used for data transmission or data channels, the first scaling factor and the second scaling factor being used to determine a third scaling factor, the third scaling factor being used to determine the maximum value of the ratio between the number of REs used in any one of the second information across the full-duplex area and the non-full-duplex area and the number of REs used for data transmission or data channels. Optionally, the first indication information includes the first scaling factor and / or the second scaling factor, and the third scaling factor is determined based on the ratio of resources in the full-duplex area or the non-full-duplex area used in any one of the second indication information and the second information to the total resources used in any one of the second information.

[0308] In one example, the second indication information includes a first proportional factor and a second proportional factor, the first proportional factor is erfa1, the second proportional factor is erfa2, the proportion of resources in the full-duplex area or non-full-duplex area used by any item in the second information to the total resources used by any item in the second information is 1 / 2, and the third proportional factor erfa3 = (erfa1+erfa2)*1 / 2.

[0309] Optionally, the first scaling factor and the second scaling factor may be configured by higher layer signaling.

[0310] Case F: The second indication information includes a first proportional factor, and the second indication information may also include any of the following items: a first offset proportional factor or a second offset proportional factor, the first proportional factor is used to determine the maximum value of the ratio between the number of used REs of any item in the second information of the non-full-duplex area and the number of used REs for data transmission or data channels, the first proportional factor and the first offset proportional factor are used to determine the maximum value of the ratio between the number of used REs of any item in the second information of the full-duplex area and the number of used REs for data transmission or data channels, the first proportional factor and the second offset proportional factor are used to determine the maximum value of the ratio between the number of used REs of any item in the second information of the full-duplex area and the non-full-duplex area and the number of used REs for data transmission or data channels.

[0311] Optionally, the first scaling factor may be configured by higher-layer signaling, and the first offset scaling factor and the second offset scaling factor may be configured by higher-layer signaling, predefined by a protocol, or indicated by physical layer signaling.

[0312] Optionally, the first scaling factor may be an original scaling factor. It should be noted that the original scaling factor may be α in the above formulas (1), (2), and (3). It can be understood that the number of REs occupied by UCI cannot exceed a proportional value α of the number of REs used for overall uplink data transmission or PUSCH. For example, if there are 100 REs in this uplink scheduling, a maximum of 50 REs can be used for channel-associated transmission of UCI. This α can be understood as the maximum threshold ratio between the number of REs used for UCI and the number of REs used for data transmission or data channels.

[0313] It should be noted that the second indication information includes the first scaling factor, and the second indication information may also include any one of the following items: the relevant description of the first offset scaling factor or the second offset scaling factor can refer to the first indication information including the first expansion factor, and the first indication information may also include any one of the following items: the relevant description in the first offset expansion factor or the second offset expansion factor, which will not be repeated here.

[0314] In another possible example, the second indication information includes a first proportional factor, the second indication information includes a first offset proportional factor, the first proportional factor is used to determine the maximum value of the ratio between the number of REs used in any one of the second information of the non-full-duplex area and the number of REs used for data transmission or data channels, the first proportional factor and the first offset proportional factor are used to determine the maximum value of the ratio between the number of REs used in any one of the second information of the full-duplex area and the number of REs used for data transmission or data channels, the first proportional factor, the first offset proportional factor and the ratio of resources of the full-duplex or non-full-duplex area used in any one of the second information to the total resources used in any one of the second information are used to determine the maximum value of the ratio between the number of REs used in any one of the second information of the full-duplex area and the non-full-duplex area and the number of REs used for data transmission or data channels.

[0315] In another possible example, the second indication information includes a first proportional factor, and the second indication information may also include any of the following: a first offset proportional factor or a second offset proportional factor, the first proportional factor is used to determine the maximum value of the ratio between the number of used REs of any item of the second information of the full-duplex area and the number of used REs for data transmission or data channels, the first proportional factor and the first offset proportional factor are used to determine the maximum value of the ratio between the number of used REs of any item of the second information of the non-full-duplex area and the number of used REs for data transmission or data channels, the first proportional factor and the second offset proportional factor are used to determine the maximum value of the ratio between the number of used REs of any item of the second information of the full-duplex area and the non-full-duplex area and the number of used REs for data transmission or data channels.

[0316] In full-duplex areas, uplink and downlink transmissions experience severe interference and the channel environment is poor. Therefore, in full-duplex areas, symmetrical downlink area puncturing or rate matching is performed for important uplink information. That is, important uplink information can be preferentially transmitted in non-full-duplex areas or puncturing locations. This approach can reduce the interference of downlink transmission on uplink transmission. The specific implementation method is as follows:

[0317] In another possible implementation, the method further includes: receiving third information, the third information including location information of symmetrical downlink area puncturing or rate matching in the full-duplex area, or resource configuration information of symmetrical puncturing or rate matching in the full-duplex area.

[0318] Optionally, the receiving of the third information may refer to the first device receiving the third information from the second device.

[0319] Optionally, a possible example of puncturing is as follows: assuming that 100 REs are available for uplink scheduling and UCI uses 10 REs, the uplink data information is still mapped to data resources on the 100 REs, but the 10 punctured REs will be used by UCI, that is, the 10 REs do not actually transmit the content mapped with the uplink data information, but actually transmit the UCI information. The uplink data information can rely on the information on other normally transmitted REs, for example, the information on the remaining 90 REs other than the 10 REs used by UCI is recovered through channel decoding.

[0320] Optionally, in a possible example of rate matching, assuming that 100 REs are available for uplink scheduling and UCI uses 10 REs, the uplink data information is mapped to data resources on the remaining 90 REs.

[0321] Optionally, the location information of the symmetrical downlink area puncturing or rate matching may be location information of symmetrical downlink (DL) puncturing or rate matching, and the resource configuration information of the symmetrical downlink area puncturing or rate matching may be resource configuration information of symmetrical DL puncturing or rate matching.

[0322] Optionally, the third information may be configuration information or indication information. Optionally, the third information may be carried in one or more of the following: protocol predefinition, network configuration, high-layer signaling, or physical layer signaling.

[0323] Optionally, the location information for symmetrical downlink area puncturing or rate matching may include the location of HARQ-ACK, the location of CSI-Part1, or some important data information. Optionally, the location of the HARQ-ACK may be the location where HARQ-ACK is multiplexed onto the PUSCH, or the resource mapping location of HARQ on the PUSCH. The location of the CSI-Part1 may be the location where CSI-Part1 is multiplexed onto the PUSCH, or the resource mapping location of CSI-Part1 on the PUSCH.

[0324] Optionally, when the third information includes the location information of the symmetrical downlink area puncturing or rate matching in the full-duplex area, the third information may be scrambled by a special radio network temporary indentifier (RNTI).

[0325] Optionally, the third information includes resource configuration information for symmetrical downlink area puncturing or rate matching of the full-duplex area, which may refer to adding or reconfiguring the position of HARQ-ACK and / or the position of CSI-Part1, wherein adding means adding resource configuration information to the existing symmetrical or rate matching resource configuration information, and the resource configuration information corresponds to the position of HARQ-ACK and / or the position of CSI-Part1 of the full-duplex area, or reconfiguring means reconfiguring special puncturing or rate matching resource configuration information, and the resource configuration information corresponds to the position of HARQ-ACK and / or the position of CSI-Part1 of the full-duplex area.

[0326] In an example, please refer to Figure 16, which is a schematic diagram of position information of symmetrical downlink area perforation or rate matching provided in an embodiment of the present application. (a) in Figure 16 is a schematic diagram of the data channel obtained after the terminal device multiplexes the control information to the data channel according to the mapping rule, and (b) in Figure 16 represents the position of HARQ-ACK and / or the position of CSI-Part1 in the full-duplex area. The position of HARQ-ACK and / or the position of CSI-Part1 is the position information of symmetrical downlink area perforation or rate matching.

[0327] In the above method, since the full-duplex area has both uplink and downlink transmissions, the uplink and downlink interference is relatively serious. Through the above method, that is, in the full-duplex area, for important uplink information, symmetrical downlink area punching or rate matching can be performed, which can reduce the interference of downlink transmission on important uplink feedback. In addition, the second device can also broadcast the punching / rate matching location information at any time according to the scheduled resources, such as scheduling HARQ-ACK / CSI resources, thereby improving resource utilization.

[0328] In another possible implementation, the method further includes: receiving third indication information, the third indication information being used to indicate whether to activate the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area, and whether the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area is activated is determined based on one or more of the following, the one or more of the following including: channel measurement results, capability indication information, or transmission priority.

[0329] Optionally, the third indication information may be an explicit or implicit indication in physical layer signaling.

[0330] Optionally, the third indication information may be carried in one or more of the following: protocol predefinition, network configuration, high-layer signaling, or physical layer signaling.

[0331] Optionally, the receiving of the third indication information may refer to the first device receiving the third indication information from the second device.

[0332] Optionally, the second device may determine whether to activate the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area based on one or more of the following: channel measurement results, capability indication information, or transmission priority, and then the second device sends third indication information to the first device, where the third indication information is used to indicate whether to activate the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area.

[0333] In one example, the second device determines based on the channel measurement result that the channel measurement result is greater than a first threshold value, determines the location of the puncturing or rate matching of the symmetric downlink area of ​​the activated full-duplex area, and sends a third indication message to the first device. The third indication message is used to indicate the location of the puncturing or rate matching of the symmetric downlink area of ​​the activated full-duplex area. Optionally, the third indication message is a display indication.

[0334] In another example, the first device is a terminal device, and the second device is a network device. When applied to a communication system between a terminal device and a network device, the network device determines whether to activate the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area based on the capability indication information. Specifically, the network device obtains M capability indication information of M terminal devices. Optionally, each terminal device corresponds to one capability indication information, and M is a positive integer greater than 0. The network device determines that the capability indication information of N terminal devices among the M terminal devices is less than a second threshold value, that is, the capability is relatively low, wherein M is greater than or equal to N. Optionally, the network device sends a third indication information to the N terminal devices, and the third indication information is used to indicate the determination of the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area; optionally, the third indication information is an implicit indication; optionally, the network device can also explicitly notify the (MN) terminal devices to determine whether to activate or not activate the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area.

[0335] In another example, the first device is a terminal device, and the second device is a network device. When applied to a communication system between a terminal device and a network device, the network device determines whether to activate the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area based on the transmission priority. Optionally, the transmission priority may refer to the priority of the service data transmitted by the terminal device. For example, assuming that the service data transmitted by terminal device 1 is URLLC type service data, and the priority of the service data transmitted by terminal device 2 is eMBB type service data, the priority of URLLC type service data is higher than that of eMBB type service data. Therefore, the network device sends a third indication information to terminal device 1, and the third indication information is used to indicate the activation of the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area; optionally, the third indication information is an implicit notification. Optionally, the network device may also send a third indication information to terminal device 2, and the third indication information is used to indicate the activation of the puncturing or rate matching position of the symmetric downlink area of ​​the full-duplex area. The third indication information is an explicit notification.

[0336] In the above method, since the full-duplex area has both uplink and downlink transmissions, the uplink and downlink interference is relatively serious. Through the above method, that is, in the full-duplex area, for important uplink information, symmetrical downlink area perforation or rate matching is performed, the interference of downlink transmission on important uplink feedback can be reduced, and the second device can determine whether to activate the perforation or rate matching position of the symmetrical downlink area of ​​the full-duplex area, and the indication method is simpler and more flexible.

[0337] Step S903: The first device sends a data channel to the second device.

[0338] Step S904: The second device receives the data channel.

[0339] Step S905: The second device determines control information and data information based on a mapping rule in the data channel.

[0340] This step is the reverse process of step S902. For details, please refer to the relevant description of step S902, which will not be repeated here.

[0341] In the method described in FIG. 9 , through the above manner, when the data channel includes both a full-duplex area and a non-full-duplex area, the control information can be multiplexed onto the data channel for transmission, thereby ensuring transmission reliability of the control information.

[0342] The above describes in detail the method of the embodiment of the present application, and the following provides an apparatus of the embodiment of the present application.

[0343] Please refer to FIG. 17 , which is a schematic diagram of the structure of a communication device 1700 provided in an embodiment of the present application. The communication device 1700 may include a processing unit 1701 and a transceiver unit 1702 . The details of each unit are as follows:

[0344] The processing unit 1701 is used to perform data processing. The transceiver unit 1702 can implement corresponding communication functions. The transceiver unit 1702 can also be called a communication interface or a communication module.

[0345] Optionally, the communication device 1700 may further include a storage unit, which may be used to store instructions and / or data. The processing unit 1701 may read the instructions and / or data in the storage module to implement the aforementioned method embodiment.
