Description

Communication method and device, terminal equipment and network equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on February 8, 2024, with application number 202410178242.3 and application name “Communication Methods and Apparatus, Terminal Equipment and Network Equipment”, 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 apparatus, terminal equipment, and network equipment. Background Art

[0003] In mobile communication systems, existing uplink and downlink data transmission methods can be divided into time division duplex (TDD) and frequency division duplex (FDD) modes. TDD uses time division to achieve uplink and downlink transmission. In a TDD system, reception and transmission occur at different times on the same frequency. When the TDD uplink and downlink ratios differ between adjacent cells or when different terminal devices within the same cell have different TDD ratios, the uplink transmission of one terminal device may interfere with the downlink reception of another terminal device. This interference is called cross-link interference (CLI).

[0004] With the development of related technologies, full-duplex (FD) mode is expected to be introduced in mobile communication systems. In one scenario of a full-duplex system, subband non-overlapping full-duplex (SBFD) can achieve full-duplex on the network equipment side by dividing a single carrier into non-overlapping uplink and downlink subbands, and transmitting and receiving data on these subbands separately. In other words, the network equipment supports full-duplex mode and can transmit and receive data simultaneously on the same frequency; or the network equipment supports SBFD mode and can have uplink and downlink traffic on different subbands within the same SBFD symbol area.

[0005] CLI is introduced because multiple subbands may be simultaneously transmitting and receiving within a single carrier in full-duplex mode. For example, downlink signals from neighboring base stations may interfere with the uplink signal reception of the serving base station, or downlink signals from the serving base station may cause self-interference on the uplink signal reception of the serving base station, or uplink signals from neighboring terminal devices may interfere with the downlink signal reception of the target terminal device. Summary of the Invention

[0006] In order to deal with CLI in full-duplex mode, the present application provides a communication method and apparatus, a terminal device, and a network device, in the expectation that the CLI situation on specific resources needs to be accurately measured and reported in a timely manner so that the network can take effective measures to better suppress or resist CLI, otherwise it may cause erroneous reception of the transmitted signal.

[0007] The first aspect is a communication method of the present application, comprising:

[0008] receiving resource configuration information, where the resource configuration information is used to configure one or more candidate CLI measurement resources;

[0009] performing CLI measurement according to a CLI measurement resource determined from one or more candidate CLI measurement resources;

[0010] Send CLI measurement report.

[0011] It can be seen that in order to cope with CLI in full-duplex mode, the network device can configure one or more candidate CLI measurement resources through resource configuration information. After the terminal device performs CLI measurement based on the CLI measurement resources determined by the one or more candidate CLI measurement resources, the terminal device sends a CLI measurement report to the network device. The CLI measurement report may include the CLI measurement result, and the CLI measurement result is reported to the network device through the CLI measurement report to implement CLI measurement reporting, so that the network device can perform related scheduling and other processing based on the CLI measurement result, so as to better suppress or resist CLI and avoid or reduce the impact of CLI on network stability and other performance.

[0012] In some possible examples, the resource configuration information includes at least one of the following: first resource identification information, time-frequency domain location information, or sounding reference signal SRS sequence information; the first resource identification information is used to configure the ID of one or more candidate CLI measurement resources; the time-frequency domain location information is used to configure the time-frequency domain location of one or more candidate CLI measurement resources; the SRS sequence information is used to configure the sequence of the SRS signal carried by one or more candidate CLI measurement resources.

[0013] In this way, the network configures one or more candidate CLI measurement resource IDs through the first resource identification information, so that the terminal device can obtain the available CLI measurement resources according to the identification of the CLI measurement resources.

[0014] Through the time-frequency domain location information, the terminal device can obtain the available CLI measurement resources according to the time-frequency domain location of the CLI measurement resources.

[0015] Unlike the network device instructing the attacker / interferer (the attacker / interferer refers to the terminal device that applies CLI) to send an SRS signal, and then the victim / interfered person (the victim / interfered person refers to the terminal device that is subjected to CLI) performs CLI measurement based on the sent SRS signal, the network device of this embodiment can use SRS sequence information to indicate the SRS signal received and measured by the victim / interfered person, so that the victim / interfered person can perform CLI measurement based on the indicated SRS signal.

[0016] In some possible examples, performing CLI measurement according to the CLI measurement resource determined by the one or more candidate CLI measurement resources includes:

[0017] receiving first indication information, where the first indication information is used to indicate an activation or deactivation status of one or more candidate CLI measurement resources;

[0018] Perform CLI measurement according to the one or more activated CLI measurement resources determined by the first indication information.

[0019] In this way, the activated CLI measurement resources used for CLI measurement are configured through the first indication information.

[0020] In some possible examples, the first indication information includes a bitmap, each bit in the bitmap corresponds one-to-one to each candidate CLI measurement resource in one or more candidate CLI measurement resources; each bit in the bitmap is used to indicate the activation or deactivation status of the corresponding candidate CLI measurement resource.

[0023] In this way, the activation or deactivation status of the candidate CLI measurement resource is indicated by means of identification information.

[0024] In some possible examples, the resource configuration information is carried by RRC signaling, and the first indication information is carried by MAC CE.

[0048] receiving third indication information, where the third indication information is used to indicate an activation or deactivation status of one or more candidate CLI measurement resources;

[0049] receiving fourth indication information, where the fourth indication information is used to indicate one or more CLI measurement resources from the one or more activated CLI measurement resources determined by the third indication information;

[0050] CLI measurements are performed according to one or more CLI measurement resources.

[0051] In this way, the third indication information is used to configure the activated CLI measurement resources first, and then the fourth indication information is used to configure the activated CLI measurement resources used for CLI measurement.

[0052] In some possible examples, the third indication information includes a bitmap, each bit in the bitmap corresponds one-to-one to each candidate CLI measurement resource in one or more candidate CLI measurement resources; each bit in the bitmap is used to indicate the activation or deactivation status of the corresponding candidate CLI measurement resource.

[0056] In some possible examples, the resource configuration information is carried by RRC signaling, the third indication information is carried by MAC CE, and the fourth indication information is carried by group DCI or UE specific DCI.

[0057] In this way, this embodiment first configures one or more candidate CLI measurement resources through RRC signaling, then indicates one or more activated CLI measurement resources through MAC, and finally indicates one or more CLI measurement resources through group DCI or UE-specific DCI, so as to determine the CLI measurement resources used for CLI measurement.

[0058] In some possible examples, the fourth indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI, wherein each terminal device corresponds to one resource indication field, or multiple terminal devices share one resource indication field; one resource indication field is used to indicate one CLI measurement resource from one or more activated CLI measurement resources, and the value of one resource indication field corresponds to one CLI measurement resource ID.

[0059] In this way, a CLI measurement resource used for CLI measurement is indicated from one or more activated CLI measurement resources through the resource indication field in the group DCI.

[0060] In some possible examples, the fourth indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI. Each terminal device corresponds to one resource indication field, or multiple terminal devices share one resource indication field. One resource indication field is used to indicate multiple CLI measurement resources from one or more activated CLI measurement resources, and the value of one resource indication field corresponds to one CLI measurement resource combination ID.

[0061] In this way, the resource indication field in the group DCI is used to indicate multiple CLI measurement resources used for CLI measurement from one or more activated CLI measurement resources.

[0062] In some possible examples, the fourth indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI. Each terminal device corresponds to multiple resource indication fields, or multiple terminal devices share one resource indication field; each resource indication field is used to indicate a CLI measurement resource from one or more activated CLI measurement resources, and the value of each resource indication field corresponds to a CLI measurement resource ID.

[0077] In this way, the terminal device can report one or more CLI reporting values ​​through MAC CE. After the network device receives one or more CLI reporting values, the network device can determine the CLI measurement value based on the correspondence between the CLI reporting value and the interval where the CLI measurement value is located, so as to obtain the CLI measurement result.

[0078] In some possible examples, the CLI measurement result information is carried by the UCI; the CLI measurement result information includes one or more absolute CLI reporting values, each absolute CLI reporting value corresponds to an interval in which an absolute CLI measurement value is located; and / or the CLI measurement result information includes one or more differential CLI reporting values, each differential CLI reporting value corresponds to an interval in which a differential CLI measurement value is located.

[0079] In this way, the terminal device can report one or more absolute CLI reporting values ​​and / or one or more differential reporting values ​​through the UCI. After the network device receives these CLI reporting values, the network device can determine the CLI measurement value based on the correspondence between the CLI reporting value and the interval in which the CLI measurement value is located, so as to obtain the CLI measurement result.

[0080] In some possible examples, CLI measurement result information is carried by UCI; if K ≥ 2, and K represents the number of CLI measurement resources determined by one or more candidate CLI measurement resources, then the CLI measurement result information includes an absolute CLI reporting value and one or more differential CLI reporting values; an absolute CLI reporting value corresponds to an interval within which a reference CLI measurement value is located; and each differential CLI reporting value corresponds to an interval within which remaining CLI measurement values, excluding the reference CLI measurement value, are located.

[0081] Thus, if K≥2, the terminal device may use an absolute CLI reporting value to report the interval where the reference CLI measurement value is located, and use a differential CLI reporting value to report the remaining CLI measurement values ​​except the reference CLI measurement value.

RAN can be a network composed of multiple 5G-RAN nodes, implementing wireless physical layer functions, resource scheduling and radio resource management, radio access control, and mobility management functions. 5G-RAN is connected to the UPF via the user plane interface N3 to transmit data from terminal devices; 5G-RAN establishes a control plane signaling connection with the access and mobility management function (AMF) via the control plane interface N2 to implement functions such as radio access bearer control. RAN can be any device with wireless transceiver functions, including but not limited to 5G base stations (5G node base, gNB), evolved base stations (eNB), wireless access points (WiFi AP), world interoperability for microwave access base stations (WiMAX BS), transmission receiving points (TRP), wireless relay nodes, wireless backhaul nodes, master nodes (MN) in a dual-connectivity architecture, and secondary nodes (SN) in a dual-connectivity architecture.

[0142] In addition, the access network device may refer to a device used to communicate with a terminal device. For example, the access network device may be a base transceiver station (BTS) in a global system of mobile communication (GSM) system or a code division multiple access (CDMA) system, a base station (nodeB, NB) in a wideband code division multiple access (WCDMA) system, an evolutionary node base (eNB) in an LTE system, a wireless controller in a cloud radio access network (CRAN) scenario, or a relay station, an access point, an on-board device, a wearable device, an access network device in a future 5G network, or an access network device in a future evolved PLMN network, etc., and the embodiments of the present application are not limited thereto.

[0143] In 5G NR, the functions of access network equipment are divided into two parts, called centralized unit (CU)-distributed unit (DU) separation. From the perspective of the protocol stack, the CU includes the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer of the LTE base station, and the DU includes the radio link control (RLC) layer, the media access control (MAC) layer and the physical (PHY) layer of the LTE base station. In ordinary 5G base station deployments, the CU and DU can be physically connected through optical fiber, and logically there is a specially defined F1 interface for communication between the CU and DU. From a functional perspective, the CU is mainly responsible for radio resource control and configuration, cross-cell mobility management, bearer management, etc. The DU is mainly responsible for scheduling, physical signal generation and transmission.

[0144] Optionally, the access network device can be a macro base station, a micro base station, a pico base station, a small station, a relay station, a balloon station, etc.

[0145] Core network equipment

[0146] Core network equipment may include network elements that provide various functions. "Network element" may also be referred to as an entity, device, apparatus, or module, without specific limitation. Furthermore, for ease of understanding and explanation, the term "network element" is omitted in some descriptions. For example, a network exposure function (NEF) network element is referred to as NEF. In this case, "NEF" should be understood as either an NEF network element or an NEF entity. The following descriptions of identical or similar situations are omitted.

[0147] For example, the core network equipment may include a mobility management entity (MME), a broadcast multicast service center (BMSC), etc., or may include corresponding functional entities in the 5G system, such as a core network control plane (CP) or a user plane (UP) network function, etc. The core network control plane can also be understood as a control plane function (CPF) entity of the core network.

[0148] The following describes the various network elements included in the core network equipment.

[0149] The session management function (SMF) is responsible for the control plane functions of terminal device session management, including the selection and control of user plane functions (UPF), Internet protocol (IP) address allocation, session QoS management, acquisition policy and charging control (PCC) policy, etc.

[0150] The user plane function (UPF) can serve as the anchor point for protocol data unit (PDU) session connections. It is responsible for filtering data packets, data transmission / forwarding, rate control, generating billing information, etc. for terminal devices, and provides connections to the data network (DN).

[0151] The policy control function (PCF) can provide configuration policy information for terminal devices and provide policy information for network control plane elements (such as SMF) to manage and control terminal devices; it can also generate terminal device access policies and QoS flow control policies.

[0152] The AF can interact with network elements in the core network to provide some services. For example, the AF interacts with the PCF to control service policies, interacts with the NEF to obtain some network capability information or provide some application information to the network, and provides some data network access point information to the PCF to generate routing information for corresponding data services.

[0153] NEF can be responsible for providing some network-related status information to application services.

[0154] The Authentication Server Function (AUSF) can implement 3GPP and non-3GPP access authentication.

[0155] Unified Data Management (UDM), unified data management functions, 3GPP AKA authentication, user identification, access authorization, registration, mobility, subscription, SMS management, etc.

[0156] The network slice selection function (NSSF) can determine the network slice instance that the terminal device is allowed to access based on the slice selection auxiliary information, contract information, etc. of the terminal device.

[0157] The network repository function (NRF) may be a new function that provides registration and discovery capabilities, enabling network functions (NFs) to discover each other and communicate through an API interface.

[0158] Unified data management (UDM) is responsible for the management of user identification, contract data, authentication data, and user service network element registration management.

[0159] The unified data repository (UDR) can be used by the UDM to store subscription data or read subscription data and by the PCF to store policy data or read policy data.

[0160] The network data analytics function (NWDAF) can provide network analysis services based on the request data of network services.

[0161] The network slice specific authentication and authorization function (NSSAAF) can be used to provide authentication and authorization for specific network slices.

[0162] It should be noted that terminal devices are wirelessly connected to access network devices, and access network devices are wirelessly or wiredly connected to core network devices. Access network devices and core network devices can be independent and distinct physical devices, or they can integrate the functions of core network devices and the logical functions of access network devices into the same physical device, or they can integrate some core network device functions and some access network device functions into a single physical device.

[0163] For example, Figure 2 is a schematic diagram of the architecture of another communication system according to an embodiment of the present application. The naming of each network element included in Figure 2 is only a name, and the name does not limit the function of the network element itself. In 5G networks and other future networks, the above-mentioned network elements may also have other names, and this is not specifically limited. For example, in a 6G network, some or all of the above-mentioned network elements may use the terminology used in 5G, or may have other names, etc., which are uniformly explained here and will not be repeated below.

[0164] In addition, the network elements in Figure 2 do not necessarily need to exist simultaneously, and the required network elements can be determined based on demand. The connection relationship between the network elements in Figure 2 is not unique and can be adjusted based on demand. It is understood that the above-mentioned network elements or functions can be network components in hardware devices, software functions running on dedicated hardware, or virtualized functions instantiated on a platform (e.g., a cloud platform).

[0165] Of course, FIG2 is merely an example of a network architecture of a communication system and does not constitute a limitation on the network architecture of the communication system in the embodiment of the present application.

[0166] The communication system has been described above. The CLI measurement reporting of this embodiment will be described in detail below.

[0167] In a TDD system, all frequency domain resources on a TDD carrier must transmit in the same direction at the same time, either uplink or downlink. This prevents flexible configuration of the uplink and downlink time slot ratios for different frequency domain resources on a TDD carrier. However, with the diversification of services, especially considering the needs of vertical industries, different services have different requirements for uplink and downlink transmission, making a single uplink and downlink time slot ratio unable to meet the needs of different services.

[0168] To minimize restrictions on uplink and downlink time slot allocation, flexibly utilize limited spectrum resources to dynamically match service needs, improve resource utilization efficiency, and enhance uplink coverage, latency, and other performance of data transmission, 3GPP introduced subband-based full-duplex (SBFD), also known as SBFD. This divides the frequency domain of the same carrier into non-overlapping uplink and downlink subbands, enabling both uplink and downlink transmissions to be supported at the same time, thereby improving spectrum utilization and flexibility.

[0169] In an SBFD system, the network device side operates in full duplex mode, meaning that uplink and downlink transmissions can occur simultaneously at different frequency locations at the same time. To prevent interference between uplink and downlink transmissions, a guard band (i.e., sub-band) is reserved between the frequency locations corresponding to different transmission directions. The terminal device side operates in half duplex mode, meaning that only uplink or downlink transmissions can occur at the same time, not both. In this full-duplex mode on the network device side and half-duplex mode on the terminal device side, uplink and downlink transmissions on the network device side at the same time can only be directed to different terminal devices.

[0170] In a TDD system, adjacent cells can be configured with different TDD uplink and downlink ratios, or different terminal devices in the same cell can have different TDD uplink and downlink ratios. In this way, the uplink resources configured by the network for the first terminal device in a certain cell have the same time-frequency domain position as the downlink resources of the second terminal device in the adjacent cell, or the uplink resources configured by the network for the first terminal device in the same cell have the same time-frequency domain position as the downlink resources of the second terminal device, which causes the uplink transmission of the first terminal device to interfere with the downlink reception of the second terminal device. This interference is called cross-link interference (CLI). Among them, the CLI in the TDD system can be called full-band CLI (full-band CLI).

[0171] In the SBFD system, adjacent cells can divide different uplink and downlink subbands on the same carrier, or different terminal devices in the same cell can have different uplink and downlink subbands on the same carrier. In this way, on the same carrier, the uplink subband configured by the network for the first terminal device in a certain cell has the same frequency domain position as the downlink carrier of the second terminal device in the adjacent cell, or the uplink subband configured by the network for the first terminal device in the same cell has the same frequency domain position as the downlink subband of the second terminal device, which causes the uplink transmission of the first terminal device to interfere with the downlink reception of the second terminal device. This interference also belongs to CLI. Among them, the CLI in the SBFD system can be called intra-subband CLI (intra-subband CLI) or inter-subband CLI (inter-subband CLI).

[0172] In order to cope with CLI in full-duplex mode, this embodiment considers that the CLI situation on specific resources needs to be accurately measured and reported in a timely manner so that the network can take effective measures to better suppress or resist the above-mentioned CLI interference, otherwise it may cause erroneous reception of the transmitted signal.

[0173] In addition, in a communication system, different interfaces may define their own protocol stacks, and protocols may be layered (layers), such as layer 1 (L1), layer 2 (L2), and layer 3 (L3). Layer 1 may refer to the physical layer protocol; layer 2 may refer to the data link layer, which may include the PDCP layer, the radio link control (RLC) layer, and / or the MAC layer; and layer 3 may refer to the network layer, which may include the RRC layer.

[0174] Based on this, this embodiment requires L1 / L2-based CLI measurement and reporting. The L1 / L2-based CLI measurement and reporting includes L1 / L2-based CLI-received signal strength indicator (CLI-RSSI) measurement and reporting and L1 / L2-based sounding reference signal-reference signal received power (SRS-RSRP) measurement and reporting.

[0175] For L1 / L2-based CLI-RSSI measurement reporting, this embodiment considers that the network device can instruct the victim / interferer (the victim / interferer refers to the terminal device that is subjected to CLI) to measure the total received power on the CLI-RSSI measurement resources configured by the network to obtain the CLI-RSSI measurement result. The CLI-RSSI measurement result may include CLI-RSSI.

[0176] Unlike the situation where a network device instructs an attacker / interferer (the attacker / interferer refers to a terminal device that applies CLI) to send an SRS signal, and then the victim / interfered device performs RSRP measurement based on the transmitted SRS signal, for L1 / L2-based SRS-RSRP measurement reporting, this embodiment considers that the network device instructs the victim / interfered device to receive and measure the SRS signal, so that the victim / interfered device performs RSRP measurement based on the instructed SRS signal to obtain an SRS-RSRP measurement result. The SRS-RSRP measurement result may include SRS-RSRP.

[0177] Whether it is L1 / L2-based CLI-RSSI measurement reporting or SRS-RSRP measurement reporting, it involves the network device configuring resources for CLI measurement to the terminal device, such as CLI-RSSI measurement resources or SRS-RSRP measurement resources. For ease of description, this embodiment collectively refers to "CLI-RSSI measurement resources" and "SRS-RSRP measurement resources" as "CLI measurement resources", and collectively refers to "CLI-RSSI measurement results" and "SRS-RSRP measurement results" as "CLI measurement results". That is, CLI measurement resources may include CLI-RSSI measurement resources or SRS-RSRP measurement resources, and CLI measurement results may include CLI-RSSI measurement results or SRS-RSRP measurement results.

[0178] In addition, the victim / interferenced party can send a CLI measurement report to the network device, where the CLI measurement report can include the CLI measurement result, thereby reporting the CLI measurement result. The reporting of the CLI measurement result can support event triggering or periodic reporting.

[0179] As can be seen, to cope with CLI in full-duplex mode, the network device configures resources for CLI measurement on the terminal device. The terminal device then uses these resources to perform CLI measurements, obtains CLI measurement results, and reports these results to the network device. This allows the network device to perform relevant scheduling and other processing based on the CLI measurement results, thereby better suppressing or resisting CLI and avoiding or reducing its impact on network stability and other performance issues.

[0180] The following embodiment specifically describes CLI measurement reporting based on L1 / L2 through the following solutions. These solutions can be related to each other or independent of each other, and the same contents between different solutions can be referenced by each other, which will not be repeated here.

[0181] [Scheme 1]

[0182] In "Solution 1", this embodiment needs to first perform network configuration on the CLI measurement resources, and then determine the CLI measurement resources used for CLI measurement in the CLI measurement resources configured in the network for specific description.

[0183] For example, the network device may configure one or more candidate CLI measurement resources to the terminal device through RRC signaling (i.e., the configuration process of the candidate CLI measurement resources), and then determine the CLI measurement resources used for CLI measurement from the candidate CLI measurement resources configured by the RRC signaling through a MAC control element (MAC CE) (i.e., the determination process of the CLI measurement resources).

[0184] The following describes in detail the process of configuring candidate CLI measurement resources and the process of determining CLI measurement resources.

[0185] "Configuration process of candidate CLI measurement resources"

[0186] During the configuration process of the candidate CLI measurement resources, the network device can configure one or more candidate CLI measurement resources to the terminal device through the resource configuration information. In this way, the network configures the candidate CLI measurement resources through the resource configuration information.

[0187] In some possible examples, the resource configuration information is carried by RRC signaling.

[0188] In this way, the network device can configure one or more candidate CLI measurement resources to the terminal device through RRC signaling.

[0189] In some possible examples, the resource configuration information includes resource identification information, wherein the resource identification information can be used to configure an identifier (ID) of one or more candidate CLI measurement resources.

[0190] In this way, the network device can configure the identifiers of one or more candidate CLI measurement resources to the terminal device through the resource identification information, so that the terminal device can obtain the available CLI measurement resources according to the identifiers of the CLI measurement resources.

[0191] In some possible examples, the resource configuration information includes time-frequency domain location information, and the time-frequency domain location information can be used to configure the time-frequency domain locations of one or more candidate CLI measurement resources.

[0192] In this way, the network device can configure the time-frequency domain positions of one or more candidate CLI measurement resources to the terminal device through the time-frequency domain position information, so that the terminal device can obtain the available CLI measurement resources based on the time-frequency domain positions of the CLI measurement resources.

[0193] It should be noted that the time-frequency domain position of the CLI measurement resource refers to the specific time-frequency resource configured by the network device to the terminal device for CLI measurement. Among them, the time domain position of the CLI measurement resource refers to the position of the time slot, subframe or symbol used by the terminal device for CLI measurement in the time domain. The position in the time domain describes when the terminal device should perform the measurement operation. The frequency domain position of the CLI measurement resource refers to the position of the frequency band, subcarrier, resource element (RE), etc. used by the terminal device for CLI measurement in the frequency domain. The position in the frequency domain describes on which frequency bands, subcarriers or REs the terminal device should perform the measurement operation.

[0194] In some possible examples, the resource configuration information includes SRS sequence information, where the SRS sequence information is used to configure a sequence of SRS signals carried by one or more candidate CLI measurement resources.

[0195] It should be noted that, unlike the network device instructing the attacker / interferer to send an SRS signal, and then the victim / interfered party performs CLI measurement based on the sent SRS signal, this embodiment considers that the network device can instruct the victim / interfered party to receive and measure the SRS signal, so that the victim / interfered party can perform CLI measurement based on the indicated SRS signal to obtain the CLI measurement result.

[0196] In this way, the network device can indicate the SRS signal received and measured by the terminal device through the SRS sequence information, so that the terminal device performs CLI measurement according to the indicated SRS signal.

[0197] The following describes the sequence of SRS signals using 5G NR as an example. For an SRS resource with OFDM symbol l′ and SRS antenna port i, the sequence of SRS signals carried by the SRS resource is generated according to the following formula:

[0198] The meaning of each parameter in the above formula is explained below.

[0199] Expressed as the length of the sequence of the SRS signal, it can be defined as:

[0200] in, Indicates the number of subcarriers contained in 1 RB; K TC It is expressed as the transmission comb number and is configured by high-level parameters, such as transmissionComb configuration K TC .

[0201] Table 1

[0202] m SRS,b Indicates the number of physical resource blocks (PRBs) for SRS transmission, a high-level parameter C configured by high-level signaling SRS and high-level parameters B SRS Determine, as shown in Table 1. Wherein, b = B SRS , B SRS ∈{0,1,2,3} is given by the field b-SRS in the high-level parameter freqHopping; CSRS ∈{0,1,...,63} is given by the c-SRS field in the high-level parameter freqHopping, b hop ∈{0,1,2,3} is given by the field b-hop contained in the high-level parameter freqHopping; m SRS,0 It can represent the total bandwidth of SRS frequency hopping.

[0203] It is expressed as low-PAPR pseudo-random sequences, which can be defined as:

[0204] in, Expressed as The length of , α is the cyclic shift, represents a basic sequence, u∈{0,1,...,29} represents the group number, and v represents The basic sequence number in the group, δ = log2(K TC ).

[0205] α i Expressed as SRS antenna port i(p i ), which can be defined as:

[0206] in, It is expressed as the number of cyclic shifts and is configured by high-level parameters; for example, transmissionComb configuration is the maximum number of cyclic displacements, and The value of K TC The value of is determined. For example, when K TC When the value range of is {2,4,8}, The values ​​of are given in Table 2.

[0207] It should be noted that K TC It can be expressed that there are many SRS antenna ports with the possibility of frequency domain orthogonality, and It can indicate how many SRS antenna ports have the possibility of code division orthogonality in the code domain. Since orthogonality needs to be guaranteed between different SRS antenna ports or different terminal devices, (like ) indicates how many orthogonal quadratures can be accommodated in total.

[0208] Table 2

[0209] "CLI Measurement Resource Determination Process"

[0210] After the network configures one or more candidate CLI measurement resources, the network device may indicate to the terminal device the activation or deactivation status of each of the one or more candidate CLI measurement resources through indication information. In this way, the terminal device performs CLI measurements based on the one or more activated CLI measurement resources.

[0211] Activating CLI measurement resources means the network device notifies the terminal device, via a MAC CE, that it needs to use the activated CLI measurement resources for CLI measurements. After receiving the activation configuration, the terminal device can perform CLI measurements at the time-frequency domain locations of the activated CLI measurement resources, as required by the network configuration, and report the measurement results.

[0212] Deactivating a CLI measurement resource means the network device notifies the terminal device, via a MAC CE, that it will not use the deactivated CLI measurement resource for CLI measurements. Upon receiving the deactivation configuration, the terminal device ceases the corresponding CLI measurement operations and no longer reports the relevant measurement results.

[0213] As can be seen, by activating or deactivating CLI measurement resources, network devices can flexibly control the CLI measurement behavior of terminal devices as needed, effectively managing network resources and avoiding resource waste caused by excessive CLI measurement tasks. Furthermore, network devices can dynamically adjust the activation or deactivation status of CLI measurement resources based on real-time network conditions and needs, thereby obtaining accurate network performance information and performing corresponding network optimization.

[0214] In some possible examples, the indication information may be carried by a MAC CE. In this way, the network device may indicate the activation or deactivation status of each candidate CLI measurement resource to the terminal device via the MAC CE.

[0215] In some possible examples, the indication information may include a bitmap. In this way, the network device may indicate the activation or deactivation status of each candidate CLI measurement resource to the terminal device in a bitmap manner.

[0216] It should be noted that each bit in the bitmap corresponds one-to-one to each candidate CLI measurement resource. That is, the number of bits in the bitmap is the same as the number of candidate CLI measurement resources configured by the network. For example, if RRC signaling configures 8 candidate CLI measurement resources, the number of bits in the bitmap is 8.

[0217] Each bit in the bitmap may be used to indicate the activation or deactivation status of its corresponding candidate CLI measurement resource.

[0218] For example, if the value of the bit is 1, the candidate CLI measurement resource corresponding to the bit is in the activated state; if the value of the bit is 0, the candidate CLI measurement resource corresponding to the bit is in the deactivated state. Conversely, if the value of the bit is 1, the candidate CLI measurement resource corresponding to the bit is in the deactivated state; if the value of the bit is 0, the candidate CLI measurement resource corresponding to the bit is in the activated state.

[0219] In some possible examples, the indication information may include one or more identification information. In this way, the network device may inform the terminal device of the activation or deactivation status of each candidate CLI measurement resource through the one or more identification information.

[0220] It should be noted that each of the one or more identification information corresponds one-to-one to each of the one or more candidate CLI measurement resources. That is, the number of identification information is the same as the number of candidate CLI measurement resources configured by the network.

[0221] Each identification information may be used to indicate the activation or deactivation status of the corresponding candidate CLI measurement resource. For example, if the identification information is a first value, the candidate CLI measurement resource corresponding to the identification information is in an activated state; if the identification information is a second value, the candidate CLI measurement resource corresponding to the identification information is in a deactivated state.

[0222] In some possible examples, the indication information may include one or more fields of a MAC CE. In this way, the network device may transmit the activation or deactivation status of each candidate CLI measurement resource to the terminal device via the MAC CE.

[0223] It should be noted that each of the one or more fields corresponds one-to-one to each of the one or more candidate CLI measurement resources. That is, the number of fields is the same as the number of candidate CLI measurement resources configured by the network.

[0224] Each field may be used to indicate the activation or deactivation status of its corresponding candidate CLI measurement resource.

[0225] For example, as shown in Figure 3, a MAC CE is identified by a MAC subheader, whose logical channel ID (LCID) is a specific value. The MAC CE includes the following fields:

[0226] S i Field: This field can be used to indicate the activation or deactivation status of the i-th (i=0, 1, ..., M-1) candidate CLI measurement resource, and the length of this field is 1 bit; M represents the number of candidate CLI measurement resources; when S i When it is 1, it means that the i-th candidate CLI measurement resource is activated; when S i When it is 0, it indicates that the CLI measurement resource of the i-th candidate is in deactivated state.

[0227] R field: This field indicates reservation;

[0228] Of course, FIG3 is only an example of the structure of the MAC CE, and this embodiment does not limit the structure of the MAC CE.

[0229] The following describes "Solution 1" by taking the interaction between a network device and a terminal device as an example, as shown in FIG4 , which is a flowchart of a CLI measurement method according to an embodiment of the present application. In FIG4 , the method includes the following steps:

[0230] S410. The network device sends resource configuration information, where the resource configuration information is used to configure one or more candidate CLI measurement resources.

[0231] Correspondingly, the terminal device receives resource configuration information.

[0232] S420: The network device sends first indication information, where the first indication information is used to indicate an activation or deactivation status of one or more candidate CLI measurement resources.

[0233] Correspondingly, the terminal device receives the first indication information.

[0234] S430. The terminal device performs CLI measurement according to one or more activated CLI measurement resources determined by the first indication information.

[0235] It can be seen that the network device can configure one or more candidate CLI measurement resources through resource configuration information, and then indicate the activation or deactivation status of each candidate CLI measurement resource through first indication information to determine the CLI measurement resource used for CLI measurement. In this way, the terminal device can perform CLI measurement based on the one or more activated CLI measurement resources to obtain CLI measurement results.

[0236] In some possible examples, the resource configuration information includes at least one of the following: first resource identification information, time-frequency domain location information, or SRS sequence information; the first resource identification information is used to configure the ID of one or more candidate CLI measurement resources; the time-frequency domain location information is used to configure the time-frequency domain location of one or more candidate CLI measurement resources; the SRS sequence information is used to configure the sequence of the SRS signal carried by one or more candidate CLI measurement resources.

[0237] In this way, the network device can implement network configuration of one or more candidate CLI measurement resource IDs through the first resource identification information, so that the terminal device can obtain the available CLI measurement resources according to the identification of the CLI measurement resources.

[0238] The network device can realize the time-frequency domain position of one or more candidate CLI measurement resources of the network device through the time-frequency domain position information, so that the terminal device can obtain the available CLI measurement resources according to the time-frequency domain position of the CLI measurement resources.

[0239] The network device may indicate the SRS signal received and measured by the terminal device through the SRS sequence information, so that the terminal device performs CLI measurement according to the indicated SRS signal.

[0240] In some possible examples, the first indication information includes a bitmap, each bit in the bitmap corresponds one-to-one to each candidate CLI measurement resource in one or more candidate CLI measurement resources; each bit in the bitmap is used to indicate the activation or deactivation status of the corresponding candidate CLI measurement resource.

[0241] In this way, the activation or deactivation status of the candidate CLI measurement resource is indicated by means of a bitmap.

[0242] In some possible examples, the first indication information includes one or more identification information, each of the one or more identification information corresponds one-to-one to each of the one or more candidate CLI measurement resources; each of the one or more identification information is used to indicate the activation or deactivation status of the corresponding candidate CLI measurement resource.

[0243] In this way, the activation or deactivation status of the candidate CLI measurement resource is indicated by means of identification information.

[0244] In some possible examples, the resource configuration information is carried by RRC signaling, and the first indication information is carried by MAC CE.

[0245] In this way, this embodiment first configures one or more candidate CLI measurement resources in the network through RRC signaling, and then indicates the activation or deactivation status of each candidate CLI measurement resource through MAC CE, so as to determine the CLI measurement resource used for CLI measurement.

[0246] [Scheme 2]

[0247] In Solution 2, this embodiment requires network configuration of CLI measurement resources, and then determines the CLI measurement resources used for CLI measurement from the network-configured CLI resources. Unlike Solution 1, Solution 2 may use different signaling during the configuration and determination of candidate CLI measurement resources.

[0248] For example, the network device may configure one or more candidate CLI measurement resources to the terminal device through RRC signaling, and then determine the CLI measurement resource used for CLI measurement from the candidate CLI measurement resources configured by the RRC signaling through downlink control information (DCI).

[0249] For another example, the network device may configure one or more candidate CLI measurement resources to the terminal device through MAC CE, and then determine the CLI measurement resource used for CLI measurement from the candidate CLI measurement resources configured by MAC CE through DCI.

[0250] The following describes in detail the process of configuring candidate CLI measurement resources and the process of determining CLI measurement resources.

[0251] "Configuration process of candidate CLI measurement resources"

[0252] During the configuration process of the candidate CLI measurement resources, the network device can configure one or more candidate CLI measurement resources to the terminal device through the resource configuration information. In this way, the network configures the candidate CLI measurement resources through the resource configuration information.

[0253] In some possible examples, the resource configuration information is carried by RRC signaling.

[0254] In this way, the network device can configure one or more candidate CLI measurement resources to the terminal device through RRC signaling.

[0255] In some possible examples, the resource configuration information is carried by MAC CE.

[0256] In this way, since MAC CE signaling belongs to L1 / L2 signaling, this embodiment can perform L1 / L2-based CLI measurement.

[0257] In some possible examples, the resource configuration information includes resource identification information, wherein the resource identification information can be used to configure an identifier (ID) of one or more candidate CLI measurement resources.

[0258] In this way, the network device can configure the identifiers of one or more candidate CLI measurement resources to the terminal device through the resource identification information, so that the terminal device can obtain the available CLI measurement resources according to the identifiers of the CLI measurement resources.

[0259] In some possible examples, the resource configuration information includes time-frequency domain location information, and the time-frequency domain location information can be used to configure the time-frequency domain locations of one or more candidate CLI measurement resources.

[0260] In this way, the network device can configure the time-frequency domain positions of one or more candidate CLI measurement resources to the terminal device through the time-frequency domain position information, so that the terminal device can obtain the available CLI measurement resources based on the time-frequency domain positions of the CLI measurement resources.

[0261] In some possible examples, the resource configuration information includes SRS sequence information, where the SRS sequence information is used to configure a sequence of SRS signals carried by one or more candidate CLI measurement resources.

[0262] In this way, the network device can indicate the SRS signal received and measured by the terminal device through the SRS sequence information, so that the terminal device performs CLI measurement according to the indicated SRS signal.

[0263] "CLI Measurement Resource Determination Process"

[0264] During the process of determining a CLI measurement resource, after the network configures one or more candidate CLI measurement resources, the network device may indicate one or more of the one or more candidate CLI measurement resources to the terminal device via indication information, thereby determining the CLI measurement resource to be used for CLI measurement. In this way, the terminal device may perform CLI measurement based on the one or more CLI measurement resources to obtain a CLI measurement result.

[0265] In some possible examples, the indication information may be a resource indication field corresponding to one or more terminal devices in a group DCI. Thus, the resource indication field in the group DCI is used to indicate the CLI measurement resource used for the CLI measurement from one or more candidate CLI measurement resources. The group DCI is described in detail below.

[0266]

group DCI

[0267] It should be noted that group DCI can be used to schedule a terminal device group. A terminal device group can be a combination of one or more terminal devices. Group DCI can be used to jointly schedule and allocate resources to one or more terminal devices to improve system efficiency. In this way, each terminal device in a terminal device group can determine its own DCI from the group DCI based on its device identity.

[0268] The group DCI may include resource indication fields corresponding to one or more terminal devices. The structure of the resource indication fields corresponding to one or more terminal devices in the group DCI may be as follows:

[0269] Method 1:

[0270] In "Method 1", each terminal device corresponds to a resource indication field, which can be used to indicate a CLI measurement resource from one or more candidate CLI measurement resources, and a resource indication field corresponds to a CLI measurement resource ID. Different resource indication fields correspond to different CLI measurement resource IDs.

[0271] For example, if the value of a resource indication field is 0, then the resource indication field corresponds to {1}, and {1} indicates a CLI measurement resource with a CLI measurement resource ID of 1.

[0272] In this way, each terminal device in the terminal device group can determine a resource indication field corresponding to itself from the group DCI according to its own terminal device identifier, and then determine a CLI measurement resource from one or more candidate CLI measurement resources according to the resource indication field, and finally perform CLI measurement based on the CLI measurement resource.

[0273] For example, the format of the group DCI is {terminal device identifier 1, resource indication field 1; terminal device identifier 2, resource indication field 2; terminal device identifier 3, resource indication field 3; ...}, where terminal device identifier 1 corresponds to resource indication field 1, terminal device identifier 2 corresponds to resource indication field 2, terminal device identifier 3 corresponds to resource indication field 3, and so on.

[0274] In this way, after the terminal device with terminal device identification 1 receives the group DCI, the terminal device can obtain resource indication field 1 according to the terminal device identification 1, and then determine a CLI measurement resource from one or more candidate CLI measurement resources according to the resource indication field 1, and finally perform CLI measurement based on the one CLI measurement resource.

[0275] Method 2:

[0276] In "Method 2", each terminal device corresponds to a resource indication field. A resource indication field can be used to indicate multiple CLI measurement resources from one or more candidate CLI measurement resources, and a resource indication field corresponds to a CLI measurement resource combination ID. A CLI measurement resource combination can refer to a combination of multiple CLI measurement resources, and different resource indication fields can correspond to different CLI measurement resource combination IDs.

[0277] For example, if the value of a resource indication field is 0, the resource indication field corresponds to {1,2}, and {1,2} represents a combination of a CLI measurement resource with a CLI measurement resource ID of 1 and a CLI measurement resource with a CLI measurement resource ID of 2.

[0278] In this way, each terminal device in the terminal device group can determine a resource indication field corresponding to itself from the group DCI according to its own terminal device identifier, and then determine multiple CLI measurement resources from one or more candidate CLI measurement resources based on the resource indication field, and finally perform CLI measurement based on the multiple CLI measurement resources.

[0279] For example, the format of the group DCI is {terminal device identifier 1, resource indication field 1; terminal device identifier 2, resource indication field 2; terminal device identifier 3, resource indication field 3; ...}, where terminal device identifier 1 corresponds to resource indication field 1, terminal device identifier 2 corresponds to resource indication field 2, terminal device identifier 3 corresponds to resource indication field 3, and so on.

[0280] In this way, after the terminal device with terminal device identification 1 receives the group DCI, the terminal device can obtain resource indication field 1 according to the terminal device identification 1, and then determine multiple CLI measurement resources from one or more candidate CLI measurement resources according to the resource indication field 1, and finally perform CLI measurement based on the multiple CLI measurement resources.

[0281] Method 3:

[0282] In "Method 3," each terminal device corresponds to a resource indication field, and multiple terminal devices share the same resource indication field. A resource indication field can be used to indicate a CLI measurement resource from one or more candidate CLI measurement resources, and a resource indication field corresponds to a CLI measurement resource ID. Different resource indication fields can correspond to different CLI measurement resource IDs.

[0283] For example, the format of the group DCI is {terminal device identifier 1, resource indication field 1; terminal device identifier 2, resource indication field 1; terminal device identifier 3, resource indication field 2; terminal device identifier 4, resource indication field 2; ...}. Terminal device identifier 1 and terminal device identifier 1 both correspond to resource indication field 1, terminal device identifier 3 and terminal device identifier 4 both correspond to resource indication field 2, and so on.

[0284] In this way, after the terminal device with terminal device identification 3 receives the group DCI, the terminal device can obtain the resource indication field 2 according to the terminal device identification 3, and then determine a CLI measurement resource from one or more candidate CLI measurement resources according to the resource indication field 2, and finally perform CLI measurement based on the one CLI measurement resource.

[0285] Method 4:

[0286] In "Method 4," each terminal device corresponds to a resource indication field, and multiple terminal devices correspond to the same resource indication field. One resource indication field can be used to indicate multiple CLI measurement resources from one or more candidate CLI measurement resources, and one resource indication field corresponds to one CLI measurement resource combination ID. Different resource indication fields can correspond to different CLI measurement resource IDs.

[0287] For example, the format of the group DCI is {terminal device identifier 1, resource indication field 1; terminal device identifier 2, resource indication field 1; terminal device identifier 3, resource indication field 2; terminal device identifier 4, resource indication field 2; ...}. Terminal device identifier 1 and terminal device identifier 1 both correspond to resource indication field 1, terminal device identifier 3 and terminal device identifier 4 both correspond to resource indication field 2, and so on.

[0288] In this way, after the terminal device with terminal device identification 3 receives the group DCI, the terminal device can obtain the resource indication field 3 according to the terminal device identification 3, and then determine multiple CLI measurement resources from one or more candidate CLI measurement resources according to the resource indication field 3, and finally perform CLI measurement based on the multiple CLI measurement resources.

[0289] Method 5:

[0290] In "Method 5", each terminal device corresponds to multiple resource indication fields, each of which can be used to indicate a CLI measurement resource from one or more candidate CLI measurement resources, and each resource indication field corresponds to a CLI measurement resource ID. Different resource indication fields can correspond to different CLI measurement resource IDs.

[0291] In this way, each terminal device in the terminal device group can determine the multiple resource indication fields corresponding to itself from the group DCI according to its own terminal device identifier, and then determine multiple CLI measurement resources from one or more candidate CLI measurement resources according to the multiple resource indication fields, and finally perform CLI measurement based on the multiple CLI measurement resources.

[0292] For example, the format of the group DCI is {terminal device identifier 1, resource indication field 1_1, resource indication field 1_2, ..., resource indication field 1_m; terminal device identifier 2, resource indication field 2_1, resource indication field 2_2, ..., resource indication field 1_n; ...}. The value of m can be equal to the value of n. Terminal device identifier 1 corresponds to m resource indication fields, and terminal device identifier 2 corresponds to n resource indication fields.

[0293] In this way, when a terminal device with terminal device identification 1 receives the group DCI, the terminal device can obtain m resource indication fields according to the terminal device identification 1, and then determine m CLI measurement resources from one or more candidate CLI measurement resources according to the m resource indication fields, and finally perform CLI measurement based on the m CLI measurement resources.

[0294] Method 6:

[0295] In "Method 6", each terminal device corresponds to multiple resource indication fields, and multiple terminal devices correspond to the same resource indication field. Each resource indication field can be used to indicate a CLI measurement resource from one or more candidate CLI measurement resources, and each resource indication field corresponds to a CLI measurement resource ID. Different resource indication fields can correspond to different CLI measurement resource IDs.

[0296] For example, the format of the group DCI is {terminal device identifier 1, resource indication field 1_1, resource indication field 1_2; terminal device identifier 2, resource indication field 1_1, resource indication field 2_1}, where terminal device identifier 1 and terminal device identifier 2 both correspond to resource indication field 1_1.

[0297] In this way, when a terminal device with terminal device identification 1 receives the group DCI, the terminal device can obtain resource indication field 1_1 and resource indication field 1_2 according to the terminal device identification 1, and then determine two CLI measurement resources from one or more candidate CLI measurement resources according to the resource indication field 1_1 and resource indication field 1_2, and finally perform CLI measurement based on the two CLI measurement resources.

[0298] In some possible examples, the indication information may be a dedicated field or an existing field in a UE-specific DCI. In this way, the dedicated field or the existing field in the UE-specific DCI is used to indicate the CLI measurement resource used for the CLI measurement from one or more candidate CLI measurement resources.

[0299]

UE specific DCI

[0300] It should be noted that UE specific DCI is applicable to scheduling a specific single terminal device.

[0301] A dedicated field in a UE-specific DCI may refer to a new field added to the existing UE-specific DCI format. This field may be specifically used to indicate the CLI measurement resources used for CLI measurement. For example, the dedicated field is used to indicate one or more CLI measurement resources from one or more candidate CLI measurement resources, and the value of the dedicated field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID. Thus, in the scheduling UE-specific DCI, the dedicated field is used to indicate one or more CLI measurement resources from one or more candidate CLI measurement resources.

[0302] The existing fields in the UE Specific DCI may refer to fields that already exist and are used in the existing UE Specific DCI format. For example, the modulation and coding scheme (MCS) field, the channel state information reference signal (CSI-RS) trigger field, etc. Therefore, this embodiment may reuse existing fields to indicate the CLI measurement resources used for CLI measurement. For example, the existing field is used to indicate one or more CLI measurement resources from one or more candidate CLI measurement resources, and the specific value of the existing field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID. In this way, when scheduling the UE specific DCI, one or more CLI measurement resources are indicated from one or more candidate CLI measurement resources through the existing field.

[0303] The following example illustrates "Solution 2" using the interaction between a network device and a terminal device as an example, as shown in Figure 5, which is a flowchart of another CLI measurement method according to an embodiment of the present application. In Figure 5, the method includes the following steps:

[0304] S510. The network device sends resource configuration information, where the resource configuration information is used to configure one or more candidate CLI measurement resources.

[0305] Correspondingly, the terminal device receives resource configuration information.

[0306] S520. The network device sends second indication information, where the second indication information is used to indicate one or more CLI measurement resources from one or more candidate CLI measurement resources.

[0307] Correspondingly, the terminal device receives the second indication information.

[0308] S530. The terminal device performs CLI measurement according to one or more CLI measurement resources.

[0309] As can be seen, the network device can configure one or more candidate CLI measurement resources using resource configuration information, and then use the second indication information to indicate one or more CLI measurement resources from the one or more candidate CLI measurement resources to determine the CLI measurement resources used for the CLI measurement. In this way, the terminal device can perform CLI measurement based on the one or more CLI measurement resources to obtain CLI measurement results.

[0310] In some possible examples, the resource configuration information includes at least one of the following: first resource identification information, time-frequency domain location information, or SRS sequence information; the first resource identification information is used to configure the ID of one or more candidate CLI measurement resources; the time-frequency domain location information is used to configure the time-frequency domain location of one or more candidate CLI measurement resources; the SRS sequence information is used to configure the sequence of the SRS signal carried by one or more candidate CLI measurement resources.

[0311] In this way, the network device can implement network configuration of one or more candidate CLI measurement resource IDs through the first resource identification information, so that the terminal device can obtain the available CLI measurement resources according to the identification of the CLI measurement resources.

[0312] The network device can realize the time-frequency domain position of one or more candidate CLI measurement resources of the network device through the time-frequency domain position information, so that the terminal device can obtain the available CLI measurement resources according to the time-frequency domain position of the CLI measurement resources.

[0313] The network device may indicate the SRS signal received and measured by the terminal device through the SRS sequence information, so that the terminal device performs CLI measurement according to the indicated SRS signal.

[0314] In some possible examples, the resource configuration information is carried by RRC signaling, and the second indication information is carried by group DCI or UE specific DCI.

[0315] In this way, this embodiment first configures one or more candidate CLI measurement resources in the network through RRC signaling, and then indicates one or more CLI measurement resources through group DCI or UE-specific DCI, so as to determine the CLI measurement resources used for CLI measurement.

[0316] In some possible examples, the resource configuration information is carried by MAC CE, and the second indication information is carried by group DCI or UE specific DCI.

[0317] In this way, this embodiment first configures one or more candidate CLI measurement resources through the MAC CE, and then indicates one or more CLI measurement resources through the group DCI or UE specific DCI, so as to determine the CLI measurement resources used for CLI measurement.

[0318] In some possible examples, the second indication information is a resource indication field corresponding to one or more terminal devices in the group DCI;

[0319] Each terminal device corresponds to a resource indication field, or multiple terminal devices correspond to the same resource indication field;

[0320] A resource indication field is used to indicate a CLI measurement resource from one or more candidate CLI measurement resources, and a value of a resource indication field corresponds to a CLI measurement resource identifier ID; or,

[0321] One resource indication field is used to indicate multiple CLI measurement resources from one or more candidate CLI measurement resources, and the value of one resource indication field corresponds to one CLI measurement resource combination ID.

[0322] In this way, the terminal device can determine a resource indication field corresponding to itself from the group DCI based on its own terminal device identifier, and then determine one or more CLI measurement resources from one or more candidate CLI measurement resources based on the resource indication field, and finally perform CLI measurement based on the one or more CLI measurement resources.

[0323] In some possible examples, the second indication information is a resource indication field corresponding to one or more terminal devices in the group DCI;

[0324] Each terminal device corresponds to multiple resource indication fields, or multiple terminal devices correspond to the same resource indication field;

[0325] Each resource indication field is used to indicate a CLI measurement resource from one or more candidate CLI measurement resources, and the value of each resource indication field corresponds to a CLI measurement resource ID.

[0326] In this way, the terminal device can determine the multiple resource indication fields corresponding to itself from the group DCI based on its own terminal device identifier, and then determine one or more CLI measurement resources from one or more candidate CLI measurement resources based on the multiple resource indication fields, and finally perform CLI measurement based on the one or more CLI measurement resources.

[0327] In some possible examples, the second indication information is a dedicated field or an existing field in the UE-specific DCI;

[0328] The dedicated field is used to indicate one or more CLI measurement resources from one or more candidate CLI measurement resources, and the value of the dedicated field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID; or,

[0329] The existing field is used to indicate one or more CLI measurement resources from one or more candidate CLI measurement resources, and a specific value of the existing field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID.

[0330] In this way, the CLI measurement resource used for CLI measurement is indicated from one or more candidate CLI measurement resources through a dedicated field or an existing field in the UE-specific DCI.

[0331] [Scheme 3]

[0332] In "Solution 3," this embodiment requires network configuration of CLI measurement resources, and then determines the CLI measurement resources used from the network-configured CLI resources. Unlike "Solution 1" or "Solution 2," "Solution 3" may utilize different signaling during the configuration and determination of candidate CLI measurement resources.

[0333] For example, the network device can configure one or more candidate CLI measurement resources to the terminal device through RRC signaling, and then determine one or more activated CLI measurement resources from the candidate CLI measurement resources configured by RRC signaling through MAC CE, and finally determine the CLI measurement resources used for CLI measurement from the activated CLI measurement resources determined by MAC CE through DCI.

[0334] The following describes in detail the process of configuring candidate CLI measurement resources and the process of determining CLI measurement resources.

[0335] "Configuration process of candidate CLI measurement resources"

[0336] During the configuration process of the candidate CLI measurement resources, the network device can configure one or more candidate CLI measurement resources to the terminal device through the resource configuration information. In this way, the network configures the candidate CLI measurement resources through the resource configuration information.

[0337] In some possible examples, the resource configuration information is carried by RRC signaling.

[0338] In this way, the network device can configure one or more candidate CLI measurement resources to the terminal device through RRC signaling.

[0339] In some possible examples, the resource configuration information is carried by MAC CE.

[0340] In this way, since MAC CE signaling belongs to L1 / L2 signaling, this embodiment can perform L1 / L2-based CLI measurement.

[0341] In some possible examples, the resource configuration information includes resource identification information, wherein the resource identification information can be used to configure an identifier (ID) of one or more candidate CLI measurement resources.

[0342] In this way, the network device can configure the identifiers of one or more candidate CLI measurement resources to the terminal device through the resource identification information, so that the terminal device can obtain the available CLI measurement resources according to the identifiers of the CLI measurement resources.

[0343] In some possible examples, the resource configuration information includes time-frequency domain location information, and the time-frequency domain location information can be used to configure the time-frequency domain locations of one or more candidate CLI measurement resources.

[0344] In this way, the network device can configure the time-frequency domain positions of one or more candidate CLI measurement resources to the terminal device through the time-frequency domain position information, so that the terminal device can obtain the available CLI measurement resources based on the time-frequency domain positions of the CLI measurement resources.

[0345] In some possible examples, the resource configuration information includes SRS sequence information, where the SRS sequence information is used to configure a sequence of SRS signals carried by one or more candidate CLI measurement resources.

[0346] In this way, the network device can indicate the SRS signal received and measured by the terminal device through RRC signaling, so that the terminal device performs CLI measurement according to the indicated SRS signal.

[0347] "CLI Measurement Resource Determination Process"

[0348] After the network configures one or more candidate CLI measurement resources, the network device can indicate the activation or deactivation status of each of the one or more candidate CLI measurement resources to the terminal device through certain indication information, so as to determine one or more activated CLI measurement resources based on the indication information.

[0349] In some possible examples, the indication information may be carried by a MAC CE. In this way, the network device may indicate the activation or deactivation status of each candidate CLI measurement resource to the terminal device via the MAC CE.

[0350] In some possible examples, the indication information may include a bitmap. Each bit in the bitmap corresponds one-to-one to each candidate CLI measurement resource. Each bit in the bitmap may be used to indicate the activation or deactivation status of its corresponding candidate CLI measurement resource. In this way, the network device may indicate the activation or deactivation status of each candidate CLI measurement resource to the terminal device via a bitmap.

[0351] In some possible examples, the indication information may include one or more identification information. Each of the one or more identification information corresponds one-to-one to each of the one or more candidate CLI measurement resources. Each identification information may be used to indicate the activation or deactivation status of its corresponding candidate CLI measurement resource. Thus, the network device may notify the terminal device of the activation or deactivation status of each candidate CLI measurement resource through the one or more identification information.

[0352] In some possible examples, the indication information may include one or more fields of a MAC CE. Each of the one or more fields corresponds one-to-one to each of the one or more candidate CLI measurement resources. Each field may be used to indicate the activation or deactivation status of its corresponding candidate CLI measurement resource. In this way, the network device may notify the terminal device of the activation or deactivation status of each candidate CLI measurement resource via a MAC CE.

[0353] The network device may then indicate one or more of the one or more activated CLI measurement resources to the terminal device through additional indication information, so as to determine the CLI measurement resources used for the CLI measurement. In this way, the terminal device may perform CLI measurement based on the one or more CLI measurement resources to obtain a CLI measurement result.

[0354] In some possible examples, the additional indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI, wherein each terminal device corresponds to one resource indication field, or multiple terminal devices share one resource indication field; one resource indication field is used to indicate one CLI measurement resource from one or more activated CLI measurement resources, and the value of one resource indication field corresponds to one CLI measurement resource ID.

[0355] In this way, a CLI measurement resource used for CLI measurement is indicated from one or more activated CLI measurement resources through the resource indication field in the group DCI.

[0356] In some possible examples, the additional indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI, wherein each terminal device corresponds to one resource indication field, or multiple terminal devices share one resource indication field; one resource indication field is used to indicate multiple CLI measurement resources from one or more activated CLI measurement resources, and the value of one resource indication field corresponds to one CLI measurement resource combination ID.

[0357] In this way, the resource indication field in the group DCI is used to indicate multiple CLI measurement resources used for CLI measurement from one or more activated CLI measurement resources.

[0358] In some possible examples, the additional indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI, wherein each terminal device corresponds to multiple resource indication fields, or multiple terminal devices share one resource indication field; each resource indication field is used to indicate a CLI measurement resource from one or more activated CLI measurement resources, and the value of each resource indication field corresponds to a CLI measurement resource ID.

[0359] In this way, the resource indication field in the group DCI is used to indicate one or more CLI measurement resources used for CLI measurement from one or more activated CLI measurement resources.

[0360] In some possible examples, the additional indication information may be a dedicated field in the UE-specific DCI; the dedicated field is used to indicate one or more CLI measurement resources from one or more activated CLI measurement resources, and the value of the dedicated field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID.

[0361] In this way, one or more CLI measurement resources are indicated from one or more activated CLI measurement resources through a dedicated field in the UE-specific DCI.

[0362] In some possible examples, the additional indication information may be an existing field in the UE-specific DCI; the existing field is used to indicate one or more CLI measurement resources from one or more activated CLI measurement resources, and the specific value of the existing field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID.

[0363] In this way, one or more CLI measurement resources are indicated from one or more activated CLI measurement resources through an existing field in the UE-specific DCI.

[0364] The following uses the interaction between a network device and a terminal device as an example to illustrate "Solution 3", as shown in Figure 6, which is a flowchart of another CLI measurement method according to an embodiment of the present application. In Figure 6, the method includes the following steps:

[0365] S610. The network device sends resource configuration information, where the resource configuration information is used to configure one or more candidate CLI measurement resources.

[0366] Correspondingly, the terminal device receives resource configuration information.

[0367] S620. The network device sends third indication information, where the third indication information is used to indicate an activation or deactivation status of one or more candidate CLI measurement resources.

[0368] Correspondingly, the terminal device receives the third indication information.

[0369] S630. The network device sends fourth indication information, where the fourth indication information is used to indicate one or more CLI measurement resources from the one or more activated CLI measurement resources determined by the third indication information.

[0370] Correspondingly, the terminal device receives the fourth indication information.

[0371] S640. The terminal device performs CLI measurement according to one or more CLI measurement resources.

[0372] It can be seen that the network device can configure one or more candidate CLI measurement resources through resource configuration information, then indicate one or more activated CLI measurement resources from the one or more candidate CLI measurement resources through third indication information, and finally indicate one or more CLI measurement resources from the one or more activated CLI measurement resources through fourth indication information to determine the CLI measurement resources used for CLI measurement. In this way, the terminal device can perform CLI measurement based on the one or more CLI measurement resources to obtain CLI measurement results.

[0373] In some possible examples, the resource configuration information includes at least one of the following: first resource identification information, time-frequency domain location information, or SRS sequence information; the first resource identification information is used to configure the ID of one or more candidate CLI measurement resources; the time-frequency domain location information is used to configure the time-frequency domain location of one or more candidate CLI measurement resources; the SRS sequence information is used to configure the sequence of the SRS signal carried by one or more candidate CLI measurement resources.

[0374] In this way, the network device can implement network configuration of one or more candidate CLI measurement resource IDs through the first resource identification information, so that the terminal device can obtain the available CLI measurement resources according to the identification of the CLI measurement resources.

[0375] The network device can realize the time-frequency domain position of one or more candidate CLI measurement resources of the network device through the time-frequency domain position information, so that the terminal device can obtain the available CLI measurement resources according to the time-frequency domain position of the CLI measurement resources.

[0376] The network device may indicate the SRS signal received and measured by the terminal device through the SRS sequence information, so that the terminal device performs CLI measurement according to the indicated SRS signal.

[0377] In some possible examples, the third indication information includes a bitmap, each bit in the bitmap corresponds one-to-one to each candidate CLI measurement resource in one or more candidate CLI measurement resources; each bit in the bitmap is used to indicate the activation or deactivation status of the corresponding candidate CLI measurement resource.

[0378] In this way, the activation or deactivation status of the candidate CLI measurement resource is indicated by means of a bitmap.

[0379] In some possible examples, the third indication information includes one or more identification information, each of the one or more identification information corresponds one-to-one to each of the one or more candidate CLI measurement resources; each of the one or more identification information is used to indicate the activation or deactivation status of the corresponding candidate CLI measurement resource.

[0380] In this way, the activation or deactivation status of the candidate CLI measurement resource is indicated by means of identification information.

[0381] In some possible examples, the resource configuration information is carried by RRC signaling, the third indication information is carried by MAC CE, and the fourth indication information is carried by group DCI or UE specific DCI.

[0382] In this way, this embodiment first configures one or more candidate CLI measurement resources through RRC signaling, then indicates one or more activated CLI measurement resources through MAC, and finally indicates one or more CLI measurement resources through group DCI or UE-specific DCI, so as to determine the CLI measurement resources used for CLI measurement.

[0383] In some possible examples, the fourth indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI, wherein each terminal device corresponds to one resource indication field, or multiple terminal devices share one resource indication field; one resource indication field is used to indicate one CLI measurement resource from one or more activated CLI measurement resources, and the value of one resource indication field corresponds to one CLI measurement resource ID.

[0384] In this way, a CLI measurement resource used for CLI measurement is indicated from one or more activated CLI measurement resources through the resource indication field in the group DCI.

[0385] In some possible examples, the fourth indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI. Each terminal device corresponds to one resource indication field, or multiple terminal devices share one resource indication field. One resource indication field is used to indicate multiple CLI measurement resources from one or more activated CLI measurement resources, and the value of one resource indication field corresponds to one CLI measurement resource combination ID.

[0386] In this way, the resource indication field in the group DCI is used to indicate multiple CLI measurement resources used for CLI measurement from one or more activated CLI measurement resources.

[0387] In some possible examples, the fourth indication information may be a resource indication field corresponding to one or more terminal devices in the group DCI. Each terminal device corresponds to multiple resource indication fields, or multiple terminal devices share one resource indication field; each resource indication field is used to indicate a CLI measurement resource from one or more activated CLI measurement resources, and the value of each resource indication field corresponds to a CLI measurement resource ID.

[0388] In this way, the resource indication field in the group DCI is used to indicate one or more CLI measurement resources used for CLI measurement from one or more activated CLI measurement resources.

[0389] In some possible examples, the fourth indication information may be a dedicated field in the UE-specific DCI; the dedicated field is used to indicate one or more CLI measurement resources from one or more activated CLI measurement resources, and the value of the dedicated field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID.

[0390] In this way, one or more CLI measurement resources are indicated from one or more activated CLI measurement resources through a dedicated field in the UE-specific DCI.

[0391] In some possible examples, the fourth indication information may be an existing field in the UE-specific DCI; the existing field is used to indicate one or more CLI measurement resources from one or more activated CLI measurement resources, and the specific value of the existing field corresponds to a CLI measurement resource ID or a CLI measurement resource combination ID.

[0392] In this way, one or more CLI measurement resources are indicated from one or more activated CLI measurement resources through an existing field in the UE-specific DCI.

[0393] [Scheme 4]

[0394] After the terminal device performs CLI measurement based on the CLI measurement resources determined by one or more candidate CLI measurement resources, the terminal device may need to send a CLI measurement report to the network device. The CLI measurement report may include the CLI measurement results, and the CLI measurement results are reported to the network device through the CLI measurement report so that the network device can perform relevant scheduling and other processing based on the CLI measurement results, so as to better suppress or resist CLI and avoid or reduce the impact of CLI on network stability and other performance.

[0395] In some possible examples, the CLI measurement report may include resource identification information, wherein the resource identification information may be used to indicate a CLI measurement resource ID corresponding to a CLI measurement resource determined by one or more candidate CLI measurement resources.

[0396] In this way, the CLI measurement resource ID corresponding to the CLI measurement resource determined by the terminal device is reported through the resource identification information, so that the network device can learn the CLI measurement resource used for CLI measurement.

[0397] In addition, when reporting resources are insufficient, such as limited time-frequency resources, limited transmission power, etc., the terminal device can preferentially discard the CLI measurement resource ID corresponding to the smaller CLI measurement value, that is, not report the CLI measurement resource ID corresponding to the smaller CLI measurement value.

[0398] In some possible examples, the CLI measurement report may include CLI measurement result information, where the CLI measurement result information may be used to indicate a measurement result obtained by performing CLI measurement on a CLI measurement resource determined based on one or more candidate CLI measurement resources.

[0399] In this way, the measurement results obtained by performing CLI measurement according to the CLI measurement resources determined by the terminal device are reported through the CLI measurement result information, so that the network device can learn these measurement results.

[0400] In addition, when reporting resources are insufficient, such as limited time-frequency resources, limited transmission power, etc., the terminal device can preferentially discard smaller CLI measurement values, that is, not report smaller CLI measurement values.

[0401] This embodiment will now specifically describe the information included in the CLI measurement report in the following manners.

[0402] Method 1

[0403] In "Method 1", the terminal device can send a CLI measurement report through MAC CE, thereby reporting the CLI measurement results through MAC CE.

[0404] It should be noted that when the CLI measurement report includes resource identification information, the resource identification information is carried by the MAC CE, thereby enabling the reporting of the CLI measurement resources used for the CLI measurement via the MAC CE. When the CLI measurement report includes CLI measurement result information, the CLI measurement result information is carried by the MAC CE, thereby enabling the reporting of the measurement result via the MAC CE.

[0405] In some possible examples, the resource identification information includes one or more CLI measurement resource ID values, each corresponding to a CLI measurement resource ID. The CLI measurement resource ID values ​​correspond one-to-one to the CLI measurement resources determined by the one or more candidate CLI measurement resources. In other words, the number of CLI measurement resource ID values ​​is the same as the number of CLI measurement resources determined by the one or more candidate CLI measurement resources.

[0406] In this way, the terminal device can report one or more CLI measurement resource ID values ​​through MAC CE. After the network device receives one or more CLI measurement resource ID values, the network device can obtain the CLI measurement resources used for CLI measurement.

[0407] In some possible examples, the CLI measurement result information includes one or more CLI reported quantity values, and each CLI reported value corresponds to an interval where a CLI measured quantity value is located.

[0408] In this way, the terminal device can report one or more CLI reporting values ​​through MAC CE. After the network device receives one or more CLI reporting values, the network device can determine the CLI measurement value based on the correspondence between the CLI reporting value and the interval where the CLI measurement value is located, so as to obtain the CLI measurement result.

[0409] It should be noted that, for CLI-RSSI measurement, the CLI measurement value may include CLI-RSS; for SRS-RSRP measurement, the CLI measurement value may include SRS-RSRP.

[0410] In addition, the CLI reporting value can be an index and can be represented by a small number of bits, such as 7 bits. Because the CLI measurement value contains a large amount of information, while the CLI reporting value requires only a small amount of information, this embodiment can establish a correspondence between the CLI reporting value and the interval in which the CLI measurement value lies. In this way, the terminal device only needs to report the CLI reporting value to realize the reporting of the CLI measurement value through the above correspondence. Because the CLI reporting value contains less information than the CLI measurement value, this helps reduce the signaling overhead and resource overhead required for reporting measurement results.

[0411] The following uses the correspondence between the CLI reported value and the interval of the CLI measured value as an example to illustrate.

[0412] For example, as shown in Table 3, Table 3 shows the correspondence between the CLI reporting value and the interval where the SRS-RSRP is located. Among them, SRS-RSRP_0 represents an index, SRS-RSRP<-140 represents the interval where the SRS-RSRP is located, and the rest can be understood similarly.

[0413] Table 3

[0414] For another example, as shown in Table 4, Table 4 shows the correspondence between the CLI reported value and the range in which the CLI-RSSI is located. Among them, CLI-RSSI_00 represents an index, CLI-RSSI<-100 represents the range in which the CLI-RSSI is located, and the rest are similar.

[0415] Table 4

[0416] In some possible examples, the CLI measurement result information includes one or more CLI measurement values. The CLI measurement values ​​correspond one-to-one with the CLI measurement resources determined by the one or more candidate CLI measurement resources. In other words, the number of CLI measurement values ​​is the same as the number of CLI measurement resources determined by the one or more candidate CLI measurement resources. In this way, the terminal device can directly report the CLI measurement values ​​via a MAC CE.

[0417] In some possible examples, each CLI measurement resource ID value in the resource identification information occupies M bits of the MAC CE, and each CLI reporting value in the CLI measurement result information occupies N bits of the MAC CE, where M and N are positive integers.

[0418] The following example uses M as 5 and N as 9, as shown in Figure 7. In Figure 7, a MAC CE is identified by a MAC subheader, whose logical channel ID (LCID) is a specific value. The MAC CE includes resource identification information and CLI measurement result information. The resource identification information includes one or more CLI measurement resource ID values, each of which occupies 5 bits. The CLI measurement result information includes one or more CLI reported values, each of which occupies 7 bits.

[0419] Method 2

[0420] In "Method 2", the terminal device can send a CLI measurement report through UCI, thereby reporting the CLI measurement results through UCI.

[0421] It should be noted that when the CLI measurement report includes resource identification information, the resource identification information is carried by the UCI, thereby realizing the reporting of the CLI measurement resources used for the CLI measurement through the UCI. When the CLI measurement report includes CLI measurement result information, the CLI measurement result information is carried by the UCI, thereby realizing the reporting of the measurement result through the UCI.

[0422] In some possible examples, the resource identification information includes one or more CLI measurement resource ID values, each CLI measurement resource ID value corresponding to a CLI measurement resource ID, wherein the CLI measurement resource ID value corresponds one-to-one to the CLI measurement resource determined by the one or more candidate CLI measurement resources.

[0423] In this way, the terminal device can report one or more CLI measurement resource ID values ​​through UCI. After the network device receives one or more CLI measurement resource ID values, the network device can obtain the CLI measurement resources used for CLI measurement.

[0424] In some possible examples, resource identification information occupies UCI bits, K represents the number of CLI measurement resources determined by one or more candidate CLI measurement resources.

[0425] For example, if the number of CLI measurement resources determined by one or more candidate CLI measurement resources is 8, then 3 bits are required to indicate the CLI measurement resource IDs corresponding to the 8 CLI measurement resources. Thus, compared to using 8 bits to indicate the CLI measurement resource IDs separately, using 3 bits can reduce signaling overhead and resource overhead.

[0426] In some possible examples, the CLI measurement result information includes one or more absolute CLI reported quantity values ​​and / or one or more differential CLI reported quantity values; each absolute CLI reported value corresponds to an interval in which an absolute CLI measurement value (absolute measured quantity value) is located, and each differential CLI reported value corresponds to an interval in which a differential CLI measurement value (differential measured quantity value) is located.

[0427] In this way, the terminal device can report one or more absolute CLI reporting values ​​and / or one or more differential reporting values ​​through the UCI. After the network device receives these CLI reporting values, the network device can determine the CLI measurement value based on the correspondence between the CLI reporting value and the interval in which the CLI measurement value is located, so as to obtain the CLI measurement result.

[0428] It should be noted that the absolute CLI measurement value refers to the original CLI measurement value, that is, the reported CLI measurement value is its own value; the absolute CLI reported value refers to the CLI reported value corresponding to the absolute CLI measurement value.

[0429] A differential CLI measurement value refers to the difference between the absolute CLI measurement value and the reference CLI measurement value; a differential CLI reporting value refers to the CLI reporting value corresponding to the differential CLI measurement value. The reference CLI measurement value can be a CLI measurement value obtained by performing CLI measurement based on a reference CLI measurement resource, can be a maximum value among all CLI measurement values ​​obtained by the terminal device, or can be a specific value configured by the network, pre-configured, or specified by the protocol. For reference CLI measurement resources, the network device configures the reference CLI measurement resources to the terminal device through signaling.

[0430] In addition, both the absolute CLI reporting value and the differential CLI reporting value can be an index and can be represented by a small number of bits.

[0431] Since the differential CLI measurement value is a difference value, the amount of information of the differential CLI measurement value is smaller than that of the absolute CLI measurement value, so the amount of information of the differential CLI reporting value is also smaller than that of the absolute CLI reporting value.

[0432] Table 5

[0433] For example, taking the structure of UCI as an example, as shown in Table 5, in Table 5, the resource identification information occupies bits, the differential CLI reporting value is 4 bits, and the absolute CLI reporting value is 7 bits.

[0434] In this way, compared with reporting the absolute CLI reporting value, reporting the differential CLI reporting value has less signaling overhead and resource overhead, which is conducive to saving overhead.

[0435] The following is an example of the correspondence between the differential CLI reported value and the interval in which the differential CLI measured value lies.

[0436] For example, as shown in Table 6, Table 6 shows the correspondence between the differential CLI reported value and the interval in which the differential SRS-RSRP is located. Among them, DIFFRSRP_0 represents an index, 0≥ΔRSRP>-2 represents the interval in which the differential SRS-RSRP (i.e., ΔRSRP) is located, and the rest can be understood similarly.

[0437] Table 6

[0438] In some possible examples, if K ≥ 2, and K represents the number of CLI measurement resources determined by one or more candidate CLI measurement resources, then the CLI measurement result information includes an absolute CLI reporting value and one or more relative CLI reporting values. Each absolute CLI reporting value corresponds to an interval within which a reference CLI measurement value is located, and each differential CLI reporting value corresponds to an interval within which remaining CLI measurement values, excluding the reference CLI measurement value, are located.

[0439] It can be understood that if K≥2, the terminal device can use the absolute CLI reporting value to report the interval where the reference CLI measurement value is located, and the remaining CLI measurement values ​​except the reference CLI measurement value can be reported using the differential CLI reporting value.

[0440] For example, if K≥2, when the reference CLI measurement value is the maximum CLI measurement value, the interval in which the reference CLI measurement value is located is reported using a 7-bit absolute CLI reporting value, and the intervals in which the remaining CLI measurement values ​​are located are reported using a 4-bit differential CLI reporting value.

[0441] In this way, the terminal device can report one or more absolute CLI reporting values ​​and / or one or more differential reporting values ​​through the MAC CE. After the network device receives these CLI reporting values, the network device can determine the CLI measurement value based on the correspondence between the CLI reporting value and the interval in which the CLI measurement value is located, so as to obtain the CLI measurement result.

[0442] The following example illustrates "Solution 4" using the interaction between a network device and a terminal device as an example, as shown in Figure 8, which is a flow chart of a CLI measurement reporting method according to an embodiment of the present application. In Figure 8, the method includes the following steps:

[0443] S810. The network device sends resource configuration information, where the resource configuration information is used to configure one or more candidate CLI measurement resources.

[0444] Correspondingly, the terminal device receives resource configuration information.

[0445] S820. The terminal device performs CLI measurement according to the CLI measurement resource determined by one or more candidate CLI measurement resources.

[0446] S830. The terminal device sends a CLI measurement report.

[0447] It can be seen that in order to cope with CLI in full-duplex mode, the network device can configure one or more candidate CLI measurement resources through resource configuration information. After the terminal device performs CLI measurement based on the CLI measurement resources determined by the one or more candidate CLI measurement resources, the terminal device sends a CLI measurement report to the network device. The CLI measurement report may include the CLI measurement result, and the CLI measurement result is reported to the network device through the CLI measurement report, so that the network device can perform relevant scheduling and other processing based on the CLI measurement result, so as to better suppress or resist CLI and avoid or reduce the impact of CLI on network stability and other performance.

[0448] In some possible examples, the CLI measurement report includes second resource identification information; the second resource identification information is used to indicate a CLI measurement resource ID corresponding to a CLI measurement resource determined by one or more candidate CLI measurement resources.

[0449] In this way, the CLI measurement resource ID corresponding to the CLI measurement resource determined by the terminal device is reported through the second resource identification information, so that the network device can learn the CLI measurement resource used for CLI measurement.

[0450] In some possible examples, the second resource identification information is carried by the MAC CE; the second resource identification information includes one or more CLI measurement resource ID values, each CLI measurement resource ID value occupies M bits of the MAC CE, where M is a positive integer.

[0451] In this way, the terminal device can report one or more CLI measurement resource ID values ​​through MAC CE. After the network device receives one or more CLI measurement resource ID values, the network device can obtain the CLI measurement resources used for CLI measurement.

[0452] In some possible examples, the second resource identification information is carried by the UCI; the second resource identification information occupies bits, K represents the number of CLI measurement resources determined by one or more candidate CLI measurement resources.

[0453] In this way, the terminal device can report the CLI measurement resource ID corresponding to the CLI measurement resource determined by the terminal device through the UCI, so that the network device can know the CLI measurement resource used for CLI measurement.

[0454] In some possible examples, the CLI measurement report includes CLI measurement result information; the CLI measurement result information is used to indicate a measurement result obtained by performing CLI measurement on a CLI measurement resource determined according to one or more candidate CLI measurement resources.

[0455] In this way, the measurement results obtained by performing CLI measurement according to the CLI measurement resources determined by the terminal device are reported through the CLI measurement result information, so that the network device can learn these measurement results.

[0456] In some possible examples, the CLI measurement result information is carried by the MAC CE; the CLI measurement result information includes one or more CLI reporting values, each CLI reporting value corresponds to an interval where a CLI measurement value is located; or, the CLI measurement result information includes one or more CLI measurement values.

[0457] In this way, the terminal device can report one or more CLI reporting values ​​through MAC CE. After the network device receives one or more CLI reporting values, the network device can determine the CLI measurement value based on the correspondence between the CLI reporting value and the interval where the CLI measurement value is located, so as to obtain the CLI measurement result.

[0458] In some possible examples, the CLI measurement result information is carried by the UCI; the CLI measurement result information includes one or more absolute CLI reporting values, each absolute CLI reporting value corresponds to an interval in which an absolute CLI measurement value is located; and / or the CLI measurement result information includes one or more differential CLI reporting values, each differential CLI reporting value corresponds to an interval in which a differential CLI measurement value is located.

[0459] In this way, the terminal device can report one or more absolute CLI reporting values ​​and / or one or more differential reporting values ​​through the UCI. After the network device receives these CLI reporting values, the network device can determine the CLI measurement value based on the correspondence between the CLI reporting value and the interval in which the CLI measurement value is located, so as to obtain the CLI measurement result.

[0460] In some possible examples, CLI measurement result information is carried by UCI; if K ≥ 2, and K represents the number of CLI measurement resources determined by one or more candidate CLI measurement resources, then the CLI measurement result information includes an absolute CLI reporting value and one or more differential CLI reporting values; an absolute CLI reporting value corresponds to an interval within which a reference CLI measurement value is located; and each differential CLI reporting value corresponds to an interval within which remaining CLI measurement values, excluding the reference CLI measurement value, are located.

[0461] Thus, if K≥2, the terminal device may use an absolute CLI reporting value to report the interval where the reference CLI measurement value is located, and use a differential CLI reporting value to report the remaining CLI measurement values ​​except the reference CLI measurement value.

[0462] The above mainly introduces the solution of the embodiment of the present application from the perspective of the method side.

In actual implementation, other division methods can be used.

[0464] In the case of using integrated units, FIG9 is a block diagram of functional units of a communication device according to an embodiment of the present application, wherein the communication device 900 includes a receiving unit 901 , a measuring unit 902 , and a sending unit 903 .
