Description

[Technical Field]

[0001] TECHNICAL FIELD Embodiments of the present application relate to the field of communications, and more particularly to communications methods, devices, and systems. [Background technology]

[0002] Time division duplex (TDD) is widely applied in communication systems. In TDD, time domain resources are classified into uplink time domain resources and downlink time domain resources, which are used for uplink transmission and downlink transmission, respectively. In TDD systems, uplink time domain resource allocation is limited, resulting in a small number of uplink frequency domain resources and poor uplink coverage. Subband full duplex (SBFD) includes subband non-overlapping full duplex and subband overlapping full duplex. In subband full duplex, the frequency domain resources of one downlink time domain resource are divided into one or more downlink subbands and one or more uplink subbands, thereby increasing the number of uplink frequency domain resources and improving uplink coverage. Furthermore, dynamic / flexible TDD allows different cells to use different uplink and downlink slot configurations and supports dynamic changes of uplink and downlink slot configurations, thereby improving spectral efficiency.

[0003] In SBFD and dynamic / flexible TDD, cross-link interference (CLI) between network devices is introduced. Therefore, in these two scenarios, the CLI between networks needs to be measured to suppress the impact of CLI on communication. However, how to design CLI measurement resources to avoid impacting the communication performance of cell-edge terminal devices during CLI measurement remains a challenge that needs to be solved. Summary of the Invention

[0004] The present application provides a communication method, apparatus, and system to reduce the impact of muted resources on the communication performance of edge terminal devices and improve communication efficiency.

[0005] According to a first aspect, a communication method is provided. The method may be performed by a terminal device, or may be performed by a component (e.g., a chip or a circuit) within the terminal device. This is not a limitation of the present application. For ease of description, the following uses an example in which the method is performed by a terminal for explanation.

[0006] The method may include receiving first signaling and second signaling, where the first signaling indicates transmitting the first signal on a first resource, and the second signaling indicates a second resource not used for uplink transmission, the second resource overlapping the first resource in the time domain, and the second resource including a plurality of resource elements RE in one resource block RB, the plurality of REs being REs with index nN+k, where n is an integer greater than or equal to 0 and less than or equal to 12 / N-1, k is N-1 distinct integers from 0 to N-1, and N is a positive integer; and transmitting the first signal on a third resource, where the third resource is determined based on the first resource and the second resource.

[0007] The above solution provides a frequency-domain structure of muted resources. Resource elements RE with index nN+k are muted in the frequency domain, which corresponds to spreading the time-domain signal period. Therefore, the muted resources in the frequency domain structure do not impair the single-carrier property of the Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) waveform. Therefore, cell-edge terminal devices transmitting using the DFT-S-OFDM waveform can still achieve excellent performance, and the communication of the cell-edge terminal devices is guaranteed.

[0008] In a possible design, the second resource does not overlap with the fourth resource in the time domain, and the fourth resource is a resource carrying at least one of a demodulation reference signal (DMRS) in the first signal or uplink control information (UCI) in the first signal.

[0009] According to the above solution, the second resource does not overlap with important information such as DMRS or UCI in the first signal in the time domain, so that collision between the CLI measurement and important information in the first signal is avoided.

[0010] In one possible design, the third resource is a resource other than the second resource in the first resource.

[0011] According to the above solution, if important information such as DMRS or UCI in the first signal does not overlap with the second resource used for CLI measurement in the time domain, the second resource can be used for CLI measurement, and the important information in the first signal can also be transmitted normally.

[0012] In one possible design, the second resource overlaps with the fourth resource in the time domain, and the fourth resource is a resource carrying at least one of the DMRS in the first signal or the UCI in the first signal.

[0013] According to the above solution, flexibility in measurement and scheduling is ensured.

[0014] In a possible design, the third resource is the first resource, or the third resource is a resource other than the fifth resource in the first resource, and the fifth resource is a resource other than the fourth resource in the second resource.

[0015] According to the above solution, when important information such as DMRS or UCI in the first signal overlaps with the second resource used for CLI measurement in the time domain, the transmission of the important information in the first signal is guaranteed, and the second resource can also be used for CLI measurement as much as possible, thereby improving resource utilization.

[0016] In possible designs, N is 2, 3, 4 or 6.

[0017] In a possible design, k and / or N may be indicated by second signaling or may be predefined in the protocol.

[0018] In a possible design, the transmit power spectral density of the first signal in a symbol where the first resource overlaps with the second resource is N times the transmit power spectral density of the first signal in a symbol where the first resource does not overlap with the second resource.

[0019] According to the above solution, when a part of the frequency domain resources is not used for transmission, the power of the terminal device is fully used for transmission, so that the uplink coverage performance of the cell edge terminal device is improved.

[0020] In a possible design, the second signaling indicates a starting symbol index and length of a second resource in a slot, the second signaling includes a first bitmap, bits included in the first bitmap are in one-to-one correspondence with symbols in the slot, and symbols corresponding to bits in the first bitmap whose bit values ​​are a first value belong to the second resource; or the second signaling includes a second bitmap, bits included in the second bitmap are in one-to-one correspondence with symbols other than the first symbol in the slot, and symbols corresponding to bits in the second bitmap whose bit values ​​are a first value belong to the second resource, and the first symbol is a symbol in the slot occupied by the DMRS and / or UCI carried in the first signal.

[0021] According to the above solution, the time domain location of the second resource is flexibly indicated, so that the signaling overhead is reduced as much as possible.

[0022] According to a second aspect, a communication method is provided. The method may be performed by a network device, or may be performed by a component (e.g., a chip or circuit) within the network device. This is not a limitation of the present application.

[0027] In one possible design, the third resource is a resource other than the second resource in the first resource.

[0028] According to the above solution, if important information such as DMRS or UCI in the first signal does not overlap with the second resource used for CLI measurement in the time domain, the second resource can be used for CLI measurement, and the important information in the first signal can also be transmitted normally.

[0029] In one possible design, the second resource overlaps with the fourth resource in the time domain, and the fourth resource is a resource carrying at least one of the DMRS in the first signal or the UCI in the first signal.

[0038] According to the above solution, the time domain location of the second resource is flexibly indicated, so that the signaling overhead is reduced as much as possible.

[0039] According to a third aspect, a communication method is provided. The method may be performed by a terminal device, or may be performed by a component (e.g., a chip or a circuit) within the terminal device. This is not a limitation of the present application.

IoT networks may include, for example, Internet of Vehicles. Communication methods in Internet of Vehicle systems are collectively referred to as Vehicle-to-Everything (V2X, where X can represent anything). For example, V2X can include vehicle-to-vehicle (V2V) communications, vehicle-to-infrastructure (V2I) communications, vehicle-to-pedestrian (V2P) communications, vehicle-to-network (V2N) communications, etc.

[0114] The technical solutions provided in this application may further be applied to future communication systems, such as 6th generation (6G) mobile communication systems, which are not limited in this application.

[0115] In embodiments of the present application, a terminal device may also be referred to as user equipment (UE), access terminal, subscriber unit, subscriber station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user equipment. Terminals may be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communications, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, and smart city. Terminals may be mobile phones, tablet computers, computers with wireless transceiver capabilities, wearable devices, vehicles, unmanned aerial vehicles, helicopters, airplanes, ships, robots, robotic arms, smart home devices, etc. The specific term used for terminals and specific device forms are not limited in the embodiments of the present application.

[0116] The terminal device may be a device that provides voice / data connectivity to a user, such as a handheld device or an in-vehicle device with wireless connectivity. Currently, some examples of terminals include mobile phones, tablet computers, computers with wireless transceiver capabilities (e.g., notebook computers or palmtop computers), mobile internet devices (MIDs), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical healthcare, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes (e.g., home appliances such as television sets, smart boxes, or game consoles), cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, and personal digital assistants (PDAs). The device may be a mobile device, such as a PDA, a handheld device with wireless communication capabilities, a computing device, another processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a 5G network, or a terminal device in a future evolved public land mobile network (PLMN).

[0117] Wearable devices, sometimes referred to as wearable intelligent devices, are a general term for wearable devices such as glasses, gloves, watches, clothes, and shoes that are developed by applying wearable technology to the intelligent design of everyday clothing. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not only hardware devices, but also implement powerful functions through software support, data exchange, and cloud interaction. In a broad sense, wearable intelligent devices include full-featured large devices such as smart watches or smart glasses that can implement full or partial functions independently of a smartphone, as well as devices such as various smart bands or smart jewelry for monitoring physical symptoms that are dedicated to specific types of application functions and must be used together with another device (e.g., a smartphone).

[0118] Furthermore, the terminal device may alternatively be a terminal device in an Internet of Things (IoT) system. IoT is an important part of the future development of information technology. The main technical feature of IoT is connecting things to a network by using communication technology to implement an intelligent network for interconnection between people and machines and between things. IoT technology can achieve large-scale connection, wide coverage, and low terminal power consumption by using, for example, narrow band (NB) technology.

[0119] In embodiments of the present application, the terminal device may alternatively be a vehicle or an entire vehicle, may implement communication via the Internet of Vehicles, or may be a component located in the vehicle (e.g., disposed in or attached to the vehicle), i.e., an on-board terminal device, on-board module, or on-board unit (OBU).

[0120] Furthermore, the terminal device may alternatively include sensors such as intelligent printers, train detectors, gas stations, etc. The main functions include collecting data (part of the terminal device), receiving control information and downlink data from the network devices, transmitting electromagnetic waves, and transmitting uplink data to the network devices.

[0121] In the embodiments of the present application, the network device may be any device with a radio transceiver function, including, but not limited to, a base station in a wireless fidelity (Wi-Fi) system, an evolved NodeB (eNB), a radio network controller (RNC), a NodeB (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a Home Evolved NodeB or Home NodeB (HNB)), a baseband unit (BBU), an access point (AP), a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission reception point (TRP), etc., and may be a next generation NodeB in a 5G (5G) or NR (5G-NR) system. It may be a gNB (NodeB, gNB) or transmission point (TRP or TP), one or more antenna panel groups (including multiple antenna panels) of a base station in a 5G system, or a network node forming a gNB or transmission point, such as a baseband unit (BBU), a distributed unit (DU), or a base station in a next-generation 6G communication system.

[0122] In some deployments, a gNB may include a central unit (CU) and a DU. The gNB may further include an active antenna unit (AAU). The CU implements some of the gNB's functionality, and the DU implements some of the gNB's functionality. For example, the CU processes non-real-time protocols and services and is responsible for implementing the radio resource control (RRC) layer and packet data convergence protocol (PDCP) layer functions. The DU processes physical layer protocols and real-time services and is responsible for implementing the radio link control (RLC) layer, medium access control (MAC) layer, and physical (PHY) layer functions. The AAU implements physical layer processing functions, radio frequency processing, and some of the functionality related to active antennas. Information at the RRC layer ultimately modifies or is modified from information at the PHY layer. Therefore, in this architecture, higher layer signaling (e.g., RRC layer signaling) can also be considered to be transmitted by the DU, or by the DU and AAU. It can be understood that a network device may be a device including one or more of a CU node, a DU node, and an AAU node. Furthermore, a CU can be classified as a network device in a RAN, or a network device in a core network (CN). This is not a limitation in this application.

[0123] A network device provides a service of a cell, and a terminal device communicates with the cell by using transmission resources (e.g., frequency domain resources or spectrum resources) allocated by the network device. The cell may belong to a macro base station (e.g., a macro eNB or a macro gNB), or may belong to a base station corresponding to a small cell. The small cell here may include a metro cell, a micro cell, a pico cell, a femto cell, etc. These small cells are characterized by small coverage and low transmission power, and are applicable to providing high-speed data transmission services.

[0124] In the following, an example is used to describe the network architecture to which the embodiment of the present application is applied.

[0125] 1 is a diagram of a network architecture according to an embodiment of the present application. As shown in FIG. 1, the network architecture may include a terminal device 101, a network device 102, and a core network device 103. The terminal device 101 may be connected to the network device 102 in a wireless manner and may access the core network device 103 via the network device 102. The terminal device 101 may be at a fixed location or may be mobile.

[0126] It should be noted that the number and types of network devices, terminal devices, and core network devices included in the network architecture shown in FIG. 1 are merely examples. The embodiments of the present application are not so limited. For example, the network architecture may alternatively include more or fewer terminal devices communicating with the network devices. For example, the network architecture may alternatively include more or fewer core network devices communicating with the network devices. For simplicity of description, this is not shown in the accompanying drawings. Furthermore, although the network architecture shown in FIG. 1 illustrates network devices, terminal devices, and core network devices, such application scenarios may include, but are not limited to, network devices, terminal devices, and core network devices. For example, the application scenarios may further include devices configured to support virtualized network functions. These are apparent to those skilled in the art and will not be described in detail herein.

[0127] The following first defines technical terms that may appear in the embodiments of the present application. The terms used in the implementation of the present application are only used to describe specific embodiments of the present application and are not intended to limit the present application.

[0128] 1. Sub-band non-overlapping full duplex

[0129] In TDD, time domain resources are classified into uplink time domain resources and downlink time domain resources. For example, a possible TDD uplink / downlink configuration is DDDSU as shown in Figure 2, where D denotes a downlink slot, each symbol in a downlink slot is a downlink symbol, U denotes an uplink slot, each symbol in an uplink slot is an uplink symbol, and S denotes a special slot, which includes at least a flexible symbol. The uplink time domain resource allocation is limited, resulting in reduced uplink coverage and increased delay for TDD.

[0130] A possible enhancement is to use SBFD. In SBFD, a downlink frequency band is divided into one or more uplink subbands and one or more downlink subbands, and downlink symbols are allowed to be transmitted in the uplink subbands. For example, as shown in FIG. 3, network device 0 and network device 1 each divide a frequency band into three subbands, where subband 1 and subband 3 are both normal DDDSU configurations and subband 2 is an uplink subband. Such a frequency band configuration is transmitted to the terminal device to facilitate communication of the terminal device. Therefore, compared with TDD, SBFD has more uplink resources and improves uplink coverage performance. Furthermore, each slot has uplink resources for Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) feedback, reducing delay.

[0131] Currently, network devices support full duplex (FD) SBFD, i.e., transmission on an uplink subband and reception on a downlink subband can occur simultaneously in one slot, while UEs only support half duplex (HF) SBFD, i.e., transmission on only an uplink subband and reception on only a downlink subband can occur in one slot.

[0132] 2. Dynamic / Flexible TDD

[0133] Dynamic / flexible TDD supports different cells in using different uplink and downlink slot configurations and supports dynamic changes of the uplink and downlink slot configurations. For example, as shown in FIG. 4, the slot configuration used by network device 0 is DDDSU, and the slot configuration used by network device 1 adjacent to network device 0 is DSUUU, and the slot configuration is transmitted to each terminal device of network device 0 and network device 1 to facilitate communication between the terminal devices.

[0134] 3. Cross-linking Interference

[0135] SBFD and dynamic / flexible TDD introduce crosslink interference between network devices, i.e., downlink-to-uplink interference and uplink-to-downlink interference, more specifically, interference to downlink signals transmitted by a network device to a terminal device served by the network device, and interference to uplink signals received by a neighboring network device from a terminal device served by the neighboring network device. For example, as shown in FIG. 3, network device 0 and network device 1 are two neighboring network devices, and the downlink signal of network device 0 in slot D in subband 1 causes crosslink interference to slot U in subband 2 of network device 1. As another example, as shown in FIG. 4, network device 0 and network device 1 are two neighboring network devices, and the downlink signal of network device 0 in third slot D causes crosslink interference to slot U of network device 1.

[0136] 4. Discrete Fourier Transform - Spreading - Orthogonal Frequency Division Multiplexing

[0137] Uplink edge users typically use Discrete Fourier Transform-Spread-Orthogonal Frequency Division Multiplexing (DFT-S-OFDM) waveforms for uplink transmission. DFT-S-OFDM waveforms have single-carrier characteristics and low peak-to-average power ratio (PAPR). Therefore, higher transmit power can be used to achieve better uplink edge coverage performance.

[0138] 5. Channel State Information-Interference Measurement (CSI-IM)

[0139] A network device may measure inter-cell downlink interference by configuring CSI-IM resources. CSI-IM resources support two time-frequency patterns, namely, Pattern 0 and Pattern 1. As shown in FIG. 5, the left diagram is CSI-IM Pattern 0, and the right diagram is CSI-IM Pattern 1. Four resource elements (REs) are used in each of the time-frequency patterns, but the time-frequency structures are different. The four REs in Pattern 0 are REs with indexes 0 and 1 for symbol 5 and symbol 5, and the four REs in Pattern 1 are REs with indexes 0, 1, 2, and 3 for symbol 5.

[0140] For SBFD and dynamic / flexible TDD, CLI exists, so CLI between network devices needs to be measured to suppress the impact of CLI between network devices on uplink communication. However, when CSI-IM resources in the prior art are used, for terminal devices using DFT-S-OFDM waveforms, the single-carrier characteristics of the DFT-S-OFDM waveform are lost, resulting in an increase in PAPR. As a result, the coverage performance of cell-edge terminal devices is degraded.

[0141] To solve the above-mentioned problems, the embodiments of the present application provide a new CLI measurement resource between network devices, based on which CLI measurements can be ensured without compromising the single-carrier property of the DFT-S-OFDM waveform, so as to guarantee communication of cell-edge terminal devices.

[0142] 6 is a diagram of an example of a communication method according to an embodiment of the present application. The method may be performed by a terminal device and a network device, or may be performed by a chip in the terminal device and a chip in the network device. It should be understood that FIG. 6 illustrates steps or operations of the communication method. However, these steps or operations are merely examples. In this embodiment of the present application, other operations or variations of the operations in FIG. 6 may also be performed, or appropriate transitions between steps may be performed.

[0143] S610: The terminal device receives the first signaling and the second signaling.

[0144] The network device transmits the first signaling and the second signaling accordingly.

[0145] The first signaling instructs the terminal device to transmit a first signal on a first resource. Although the network device instructs the terminal device to transmit the first signal on the first resource based on the first signaling, it should be understood that for other reasons, for example, when the first resource conflicts with another resource, the terminal device may transmit a signal on only a part of the first resource or may not transmit the first signal.

[0146] In a possible implementation, the second signaling indicates second resources that are not used for uplink transmission. In a possible implementation, the second signaling indicates that the terminal device is not expected to perform uplink transmission on the second resources. In this application, resources that are not used for transmission are equivalent to muted resources.

[0147] It should be understood that although the second signaling indicates to the terminal device that uplink transmission cannot be performed on the second resources, the terminal device may perform uplink transmission on at least some of the second resources for another reason, for example, if the first signal has a higher priority.

[0148] In a possible implementation, the second signaling indicates a second resource, which is used by the network device to perform CLI measurements. The network device may measure CLI between the network devices on the second resource. When the network device performs CLI measurements, the terminal device is not expected to perform uplink transmissions on the second resource. Otherwise, the network device receives both CLI between the network devices and an uplink signal transmitted by the terminal device on the second resource. This affects the accuracy of the CLI measurements. It should be understood that although the second signaling indicates the second resource and the second resource is used by the network device to perform CLI measurements, the network device may perform CLI measurements on a portion of the second resource or may not perform CLI measurements on the second resource for other reasons, for example, when the second resource conflicts with another resource.

[0149] The first resource overlaps with the second resource in the time domain.

[0150] It should be understood that there is no constraint on the time sequence between the first signaling and the second signaling. Specifically, the network device may transmit the first signaling before the network device transmits the second signaling, after the network device transmits the second signaling, or simultaneously with the network device transmitting the second signaling.

[0151] In a possible implementation, the second signaling is at the cell level or the group level. For example, the network device transmits the second signaling to all terminal devices served by the network device. It should be understood that when the network device performs a CLI measurement on the second resource, the specific terminal device is not expected to transmit an uplink transmission on the second resource, and all other terminal devices served by the network device are also not expected to transmit an uplink signal on the second resource. As another example, the network device transmits the second signaling to terminal devices in a first group. The terminal devices in the first group may be terminal devices located at a cell edge, terminal devices that affect the CLI measurement, or terminal devices corresponding to one or more beam directions. In this way, the accuracy of the CLI measurement can be ensured, provided that when the network device performs the CLI measurement, terminal devices that have a specific effect on the CLI measurement do not perform uplink transmission.

[0152] In a possible implementation, the second signaling indicates a frequency domain bandwidth of the second resource. Specifically, the frequency domain bandwidth may be indicated in several implementations.

[0153] Implementation 1: The second signaling indicates the frequency domain location of the second resource by indicating the starting frequency domain location and frequency domain bandwidth of the second resource.

[0154] Implementation 2: The frequency domain bandwidth of the second resource is indicated by the first signaling. For example, the frequency domain bandwidth of the second resource is the frequency domain bandwidth of the first signal, and the frequency domain bandwidth of the first signal is indicated by the first signaling.

[0155] Implementation 3: The frequency domain bandwidth of the second resource is an uplink bandwidth part (BWP), an uplink subband, or an uplink carrier.

[0156] In a possible implementation, the second signaling indicates a frequency domain location of the second resource, where the frequency domain location is a location of the second resource in one RB in the frequency domain bandwidth. For example, the frequency domain location of the second resource in one resource block (RB) may be indicated by the second signaling or the first field in the second signaling.

[0157] There may be several possible implementations for the frequency domain location of the second resource within the RB.

[0158] Implementation 1: The second resource includes a plurality of REs in one RB, the plurality of REs being REs with indices of nN+K, where n is an integer greater than or equal to 1 and less than or equal to 12 / N-1, and k represents N-1 distinct integers from 0 to N-1, where N is a positive integer. Optionally, if N is equal to 2, k represents an integer from 0 to N-1. It should be understood that the RE index of the second resource in an RB satisfying such a relationship herein means that at least one RB in the second resource satisfies the relationship, and there may be a plurality of RBs satisfying such an RB, and other RBs may have other relationships.

[0159] In embodiment 1, N is 2, 3, 4, or 6. N is a constant that is divisible by the number of REs in an RB. For example, N is divisible by 12. n is a variable that is an integer between 0 and 12 / N-1. For example, N is a constant 3, n is an integer between 0 and 3, and k represents two different numbers between 0 and 2. For example, k may be 0 and 1. In this case, the frequency domain locations of the second resource in an RB are REs with indices 0x3+0=0, 0x3+1=1, 1x3+0=3, 1x3+1=4, 2x3+0=6, 2x3+1=7, 3x3+0=9, and 3x3+1=10. As another example, N is a constant 3, n is an integer between 0 and 3, and k represents two different numbers between 0 and 2. For example, k may be 1 and 2. In this case, the frequency domain locations of the second resource within the RB are REs with indices 0x3+1=1, 0x3+2=2, 1x3+1=4, 1x3+2=5, 2x3+1=7, 2x3+2=8, 3x3+1=10, and 3x3+2=11.

[0160] Implementation 2: The frequency domain location of the second resource within an RB is an RE with an index of 2nK+, where n is an integer from 0 to 5, and k is 0 or 1. For example, Figure 7 shows the frequency domain location of the second resource within an RB when k is 0. In this case, the frequency domain locations of the second resource within an RB are REs with indexes of 0, 2, 4, 6, 8, and 10. In Figure 7, the second resource appears at symbol 5 and symbol 9 in a slot.

[0161] In implementations 1 and 2, k and / or N are indicated by the second signaling or are predefined in the protocol.

[0162] Implementation 3: The frequency domain location of the second resource within the RB is an RE with an odd or even index. It should be understood that the frequency domain location of the second resource within the RB is a "comb-shaped" location. For example, the first field in the second signaling is "0", which indicates that the frequency domain location of the second resource within the RB is an RE with an even index, or the first field in the second signaling is "1", which indicates that the frequency domain location of the second resource within the RB is an RE with an odd index. For example, Figure 7 shows the frequency domain location of the second resource within the RB when the first field is "0". In this case, the frequency domain location of the second resource within the RB is RE with indexes 0, 2, 4, 6, 8, and 10. In Figure 7, the second resource appears at symbol 5 and symbol 9 in a slot.

[0163] Implementation 4: The second resource includes a plurality of REs in one RB, and the plurality of REs are REs other than an RE with an index of nN+y among all REs in the resource block (RB), where n is an integer between 0 and 12 / N-1, y is an integer between 0 and N-1, and N is a positive integer. For example, N is a constant 3, n is an integer between 0 and 3, and y is an integer between 0 and 2. For example, y may be 0. In this case, the frequency domain locations of the second resource in the RB are REs other than REs with indexes of 0×3+0=0, 1×3+0=3, 2×3+0=6, and 3×3+0=9. That is, the frequency domain locations of the second resource in the RB are REs with indexes of 1, 2, 4, 5, 7, 8, 10, and 11. Optionally, y and / or N are indicated by the second signaling or predefined in a protocol. For other descriptions of n and N, see the description of Implementation 1. The details will not be described again here.

[0164] In a possible implementation, the second signaling indicates a time domain location of the second resource. Specifically, the time domain location can be indicated in several implementations.

[0165] Implementation 1: The second signaling indicates the time-domain location of the second resource by indicating the starting time-domain location and the time-domain length of the second resource. For example, the second signaling indicates the starting symbol index S and the length L of the second resource within a slot. It should be understood that the time-domain location of the second resource within a slot is L consecutive symbols starting from the symbol with a symbol index of S.

[0166] Implementation 2: The second signaling includes a first bitmap, where bits in the first bitmap correspond one-to-one to symbols in a slot, and a symbol corresponding to a bit having a first value in the first bitmap belongs to the second resource. For example, in the first bitmap, a "1" indicates that the symbol corresponding to the bit is a symbol of the second resource, and a "0" indicates that the symbol corresponding to the bit is not a symbol of the second resource. For example, the first bitmap uses {0,0,1,1,1,1,1,1,1,1,1,1,0,0} to indicate the location of the second resource among the 14 symbols in a slot, and the time-domain location of the second resource is the 10 symbols in the middle of the slot, i.e., the 10 symbols from the third symbol to the 12th symbol.

[0167] Implementation 3: The second signaling includes a second bitmap, where bits included in the second bitmap correspond one-to-one to symbols other than the first symbol in the slot, and a symbol corresponding to a bit having a first value in the second bitmap belongs to a second resource, where the first symbol is a symbol in the slot occupied by the DMRS and / or UCI carried in the first signal. For example, the DMRS in the first signal occupies the third and fourth symbols in a slot, and the second bitmap uses {0,0,1,1,1,1,1,1,1,1,0,0} to indicate that the time-domain location of the second resource in the slot is eight symbols from the fifth symbol to the twelfth symbol in the slot. Since the third and fourth symbols are occupied by the DMRS, the third bit in the second bitmap indicates whether the fifth symbol in the slot belongs to the second resource, and the fourth bit in the second bitmap indicates whether the sixth symbol in the slot belongs to the second resource, and so on. In this way, only 12 bits are needed so that the time domain location of the second resource can be implemented, reducing signaling overhead.

[0168] In possible implementations, the time domain location of the second resource may be periodic, semi-persistent, or aperiodic.

[0169] In a possible implementation, the first signal is a physical uplink shared channel (PUSCH). In a possible implementation, the first signal is downlink control information (DCI) or RRC for scheduling the PUSCH.

[0170] S620: The terminal device transmits a first signal on a third resource.

[0171] Correspondingly, the network device receives the first signal on the third resource.

[0172] The third resource is determined based on the first resource and the second resource.

[0173] In a possible implementation, the second resource does not overlap with the fourth resource in the time domain, and the fourth resource is a resource carrying at least one of a demodulation reference signal (DMRS) in the first signal or uplink control information (UCI) in the first signal.

[0174] In a manner predefined by the protocol or configured by the network device, the second resource is made not to overlap with important information such as DMRS or UCI in the first signal in the time domain, so that collision between the CLI measurement and the important information in the first signal is avoided.

[0175] In a possible implementation, if the second resource does not overlap with the fourth resource in the time domain, the third resource is a resource other than the second resource within the first resource group. In a possible implementation, the network device performs CLI measurement on the second resource group. If important information in the first signal, such as DMRS or UCI, does not overlap with the second resource group used for CLI measurement in the time domain, the first signal may be transmitted on a resource other than the second resource within the first resource group. In other words, the terminal device does not transmit an uplink signal on the second resource group. In this way, the second resource group is used for CLI measurement, ensuring that the important information in the first signal can also be transmitted successfully. Furthermore, other parts of the first signal may also be transmitted on the remaining resources as much as possible.

[0176] In another possible implementation, the second resource overlaps with the fourth resource in the time domain. In this case, there are several possible implementations of the third resource.

[0177] Implementation 1: The third resource is the first resource. Correspondingly, the network device does not perform CLI measurement on the second resource. When important information in the first signal, such as DMRS or UCI, overlaps in the time domain with the second resource used for CLI measurement, the terminal device ignores all second resources and normally transmits the first signal on the first resource to ensure successful transmission of the important information in the first signal. Correspondingly, the network device also ignores the second resource and does not perform CLI measurement on the second resource. In this way, the important information in the first signal can be normally transmitted, and the network device does not perform CLI measurement on the second resource, thereby avoiding erroneous CLI measurement caused by interference with CLI measurement on resources overlapping with the first resource in the time domain during transmission of the first signal.

[0178] Implementation 2: The third resource is a resource other than the fifth resource within the first resource set, and the fifth resource is a resource other than the fourth resource within the second resource set. Accordingly, the network device performs CLI measurement on a resource other than the fourth resource within the second resource set. In other words, the network device does not perform CLI measurement on the fourth resource set. When important information, such as DMRS or UCI, within the first signal overlaps in the time domain with the second resource set used for CLI measurement, the terminal device ignores part of the second resource set and transmits the first signal on part of the first resource set to ensure successful transmission of the important information within the first signal and effective use of the second resource set. Accordingly, the network device also ignores that part of the second resource set and performs CLI measurement on the remaining part. In this way, the important information within the first signal can be successfully transmitted, and CLI measurement on part of the second resource set is guaranteed.

[0179] In a possible implementation, the transmission power spectral density of the first signal in a symbol where the first resource overlaps with the second resource is N times the transmission power spectral density of the first signal in a symbol where the first resource does not overlap with the second resource. For example, if the second resource has eight REs in one RB, the transmission power spectral density of the first signal in a symbol where the first resource overlaps with the second resource is three times the transmission power spectral density of the first signal in a symbol where the first resource does not overlap with the second resource. In this case, one-third of the 12 REs in one RB are not used for CLI measurement. As another example, if the frequency domain location of the second resource in one RB is a resource element RE with an index of 2n+k, the transmission power spectral density of the first signal in a symbol where the first resource overlaps with the second resource is twice the transmission power spectral density of the first signal in a symbol where the first resource does not overlap with the second resource. In a possible implementation, the transmission power spectral density of the first signal in symbols where the first resource does not overlap with the second resource is indicated by the first signaling. According to the above solution, when a part of the frequency domain resources is not used for transmission, the power of the terminal device is fully used for transmission so as to improve the uplink coverage performance of the cell edge terminal device.

[0180] There are several possible implementations for transmitting the first signal.

[0181] Implementation 1: The first signal is transmitted on the third resource using a rate matching scheme. In a possible implementation, the total number of coded bits transmitted in the transport block corresponding to the first signal is determined based on the third resource. For example, G is first determined based on the third resource, and then rate matching is performed based on the value of G. After that, the bit sequence output through rate matching is mapped to the third resource. G indicates the total number of coded bits available for transport block transmission. For example, B=N RE,3 ×Q m ×N L and N RE,3denotes the total number of REs included in the third resource, and Q m denotes the modulation order of the first signal, and N L indicates the number of layers of the first signal.

[0182] Implementation 2: The first signal is transmitted on the third resource using a puncturing method. For example, G is first determined based on the first resource, and then rate matching is performed based on the value of G. After that, the bit string output through rate matching is mapped to the second resource, and finally, only the first signal mapped to the third resource is transmitted. G indicates the total number of coded bits available for transport block transmission. For example, G=N RE,2 ×Q m ×N L and N RE,2 denotes the total number of REs contained in the second resource, and Q m denotes the modulation order of the first signal, and N L indicates the number of layers of the first signal.

[0183] In the above solution, the CLI measurement resources between network devices have a "comb" structure in the frequency domain, so that the single-carrier characteristics of the DFT-S-OFDM waveform are guaranteed while CLI measurements are performed between the network devices. In this way, a terminal device transmitting using a DFT-S-OFDM waveform can still achieve excellent communication quality when the network device performs CLI measurements. Furthermore, in the above solution, the influence of uplink transmission by the terminal device on CLI measurements is further reduced, so that resources for uplink transmission and CLI measurements can be fully utilized as much as possible, thereby improving communication efficiency.
