[0035] The following will be combined with the drawings in the present disclosure to clearly and completely describe the technical solutions in the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] It should be noted that, in the present disclosure, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the present disclosure should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0037] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0038] In the description of the present disclosure, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "a plurality" means two or more.

[0039] In a communication network, in order to improve spectrum utilization efficiency and reduce transmission delay, terminals and base stations can communicate through full-duplex between sub-bands.

[0040] At present, during the communication process, the terminal may be subject to uplink and downlink interference from the cell or adjacent cells. In order to ensure the reliability of full-duplex communication between sub-bands, it is necessary to perform measurements on the terminal side so that the base station can modulate the communication based on the measurement results. Currently, there is a lack of a reliable method for performing related measurements of full-duplex communication between sub-bands.

[0041] To solve the above technical problems, an embodiment of the present disclosure provides a communication method, in which the configuration information indicating the measurement resources can reflect the relevant information of the measurement that the second node expects the first node to perform. Therefore, by receiving the configuration information indicating the measurement resources, the first node can reliably perform the measurement based on the measurement resources, so that the second node can estimate the interference of the first node from the current cell or the adjacent cell on the time-frequency resources. Thus, it can be determined on which time-frequency resources the first node is subjected to strong interference, so that the second node can avoid interference when scheduling / configuring the service transmission of the first node. In this way, the reliability of communication can be improved and the performance of the communication system can be enhanced.

[0042] The communication method provided by the embodiments of the present disclosure can be applied to systems of various communication formats. For example, the communication method provided by the embodiments of the present disclosure can be applied to systems including, but not limited to, long term evolution (LTE) systems, various versions based on LTE evolution, fifth generation mobile communication technology (5G) systems, future mobile communication networks (such as 6G mobile communication networks), or multiple communication convergence systems. In addition, the communication method provided by the embodiments of the present disclosure can also be applied to future-oriented communication systems, etc.

[0043] Exemplarily, the above communication method can be applied to Figure 1 In the communication system, Figure 1 As shown, the communication system includes: a first node 101 and a second node 102.

[0044] The first node 101 is used to receive configuration information indicating measurement resources from the second node 102; or, to perform measurement based on the measurement resources to obtain a measurement report; or, to send a measurement report to the second node 102.

[0045] The second node 102 is used to send configuration information indicating measurement resources to the first node 101; or, to receive a measurement report sent by the first node 101.

[0046] In some embodiments, the first node 101 may be a terminal.

[0047] In some embodiments, the second node 102 may be a base station.

[0048] In some embodiments, the terminal can be a device with wireless transceiver function, which can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; it can also be deployed on the water surface (such as ships, etc.); it can also be deployed in the air (for example, on airplanes, balloons and satellites, etc.). The terminal can be a mobile phone, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal, an augmented reality (AR) terminal, a wireless terminal in industrial control, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in smart grid, a wireless terminal in transportation safety, a wireless terminal in smart city, a wireless terminal in smart home, etc. The embodiments of the present application do not limit the application scenarios. A terminal may sometimes also be referred to as a user, user equipment (UE), access terminal, UE unit, UE station, mobile station, mobile station, remote station, remote terminal, mobile device, UE terminal, wireless communication equipment, UE agent or UE device, etc., but the embodiments of the present application are not limited to this.

[0049] In some embodiments, the base station can be a base station or an evolved base station (eNB or eNodeB) in long term evolution (LTE), long term evolution advanced (LTEA), a base station device in a 5G network, or a base station in a future communication system, etc. The base station may include various macro base stations, micro base stations, home base stations, wireless remote stations, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices, or various network side devices such as primary cells and collaborative cells (secondary cells).

[0050] It should be noted that Figure 1 This is just an exemplary framework diagram. Figure 1 The number of devices included in the , and the names of the individual devices are not limited.

[0051] The application scenarios of the embodiments of the present disclosure are not limited. The system architecture and business scenarios described in the embodiments of the present disclosure are intended to more clearly illustrate the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. It is known to those skilled in the art that with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0052] The communication method provided by the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0053] The communication method provided by the embodiment of the present disclosure can be applied to Figure 1 A first node 101 in a communication system is shown. Figure 2 A flow chart of a communication method is shown, Figure 2 As shown, the communication method includes the following S201-S203:

[0054] S201. Receive configuration information indicating measurement resources from a second node.

[0055] It should be noted that in the inter-subband full-duplex scenario, the second node can configure one or more sets of measurement resources (or cross-link interference (CLI) measurement resources) for the first node, so that the first node performs measurements (or cross-link interference measurements) on the one or more sets of measurement resources. When cross-link interference measurements are possible, the interference to the first node from the current cell or adjacent cells on the time-frequency resources can be estimated. Thus, it can be determined which time-frequency resources the first node is subject to stronger interference, so that the second node can avoid interference when scheduling / configuring the service transmission of the first node. In this way, the reliability of communication can be improved and the performance of the communication system can be enhanced.

[0056] For example, Figure 3 As shown, it is a schematic diagram of a cross-link interference measurement resource distribution provided by an embodiment of the present disclosure. It includes the currently activated (active) (or usable) downlink part bandwidth (bandwidth part, BWP), two downlink (Down) subbands and one uplink (Up) subband and a cross-link interference received signal strength indicator physical resource block (CLI-RSSIPRB). The cross-link interference received signal strength indicator physical resource block includes resource block set 1 (RB set1), a puncturing part and a resource block set 2.

[0057] In some embodiments, the second node may configure the first node with relevant information of the measurement report corresponding to the one or more sets of measurement resources, so that the first node reports the measurement report expected by the second node according to the configuration.

[0058] In some embodiments, in order to achieve inter-subband full-duplex, the second node may configure the time domain resources and / or frequency domain resources related to inter-subband full-duplex for the first node. The time domain resources may include at least one inter-subband full-duplex time domain resource unit. The frequency domain resources may include one subband or multiple frequency-domain non-contiguous subbands (including uplink subbands and / or downlink subbands). A subband includes multiple frequency-domain continuous physical resource blocks (PRBs).

[0059] S202: Perform measurement based on the measurement resource and obtain a measurement report.

[0060] S203: Send a measurement report to the second node.

[0061] It should be understood that the configuration information indicating the measurement resources can reflect the relevant information of the measurement that the second node expects the first node to perform. Therefore, by receiving the configuration information indicating the measurement resources, the first node can reliably perform the measurement based on the measurement resources, so that the second node can estimate the interference of the first node from the cell or the adjacent cell on the time-frequency resources. Thus, it can be determined on which time-frequency resources the first node is subjected to strong interference, so that the second node can avoid interference when scheduling / configuring the service transmission of the first node. In this way, the reliability of communication can be improved and the performance of the communication system can be enhanced.

[0062] In some embodiments, the measurement resources may span multiple non-contiguous sub-bands.

[0063] In some embodiments, the measurement resource may span across multiple non-contiguous sub-bands, which may be understood as the measurement resource including a portion or all of the resources of each sub-band in the multiple non-contiguous sub-bands.

[0064] The measurement report satisfies one of the following conditions: multiple subbands each correspond to one measurement report; multiple subbands correspond to one measurement report. When multiple subbands each correspond to one measurement report, more detailed measurement results can be reported, which can adapt to scenarios with high precision requirements. Multiple subbands correspond to one measurement report, which can reduce signaling overhead and adapt to scenarios with high reporting efficiency requirements. The measurement report can meet one of the following conditions, that is, it can flexibly select the appropriate reporting method to meet the needs of different scenarios.

[0065] In some embodiments, a plurality of subbands each corresponds to a measurement report; the measurement report corresponding to a subband is obtained based on part or all of the resources on a subband; the number of physical resource blocks included in the partial resources is greater than or equal to a first value. On the one hand, the measurement report of each subband is determined based on the resources of the subband, which can achieve independent measurement of each subband and provide reliable measurement results corresponding to the subband. On the other hand, in the case where the resources on the subband are punctured or occupied by other transmissions, part of the resources on a subband other than those punctured or occupied by other transmissions can be used as measurement resources, and the measurement report corresponding to the subband is determined based on the part of the resources to adapt to more scenarios. In addition, the number of physical resource blocks included in the partial resources used to generate the measurement report is greater than or equal to the first value, which can ensure that the number of physical resource blocks participating in the measurement meets the measurement requirements and ensure the reliability of the measurement results.

[0066] In some embodiments, multiple subbands correspond to one measurement report; the measurement report also satisfies one of the following: the measurement report is determined based on the joint determination of resources on multiple subbands; the measurement report is determined based on part or all of the resources on a target subband among multiple subbands. Among them, the measurement report determined based on the joint determination of resources on multiple subbands can determine the overall interference situation corresponding to the multiple subbands by actually measuring the resources on the multiple subbands. The measurement report is determined based on part or all of the resources on a target subband among multiple subbands, and the overall interference situation of the multiple subbands can be reflected through the measurement results corresponding to the representative target subband.

[0067] In some embodiments, when the measurement report is determined based on part or all of the resources on the target subband among the multiple subbands, the number of physical resource blocks included in the partial resources is greater than or equal to a first value. Since the reliability of the measurement may be low when the number of resources participating in the measurement is small, the number of physical resource blocks included in the partial resources of the target subband used for measurement is greater than or equal to the first value, which can ensure the reliability of the measurement report obtained based on the partial resources of the target subband.

[0068] In some embodiments, the target subband is the subband with the most physical resource blocks among the multiple subbands, and the number of physical resource blocks included in the partial resources is greater than or equal to the first value. The target subband is the subband with the most physical resource blocks among the multiple subbands, which can ensure that the target subband is representative and that the measurement report obtained based on the target subband can reflect the interference conditions of the multiple subbands as a whole. The number of physical resource blocks included in the partial resources used for measurement on the target subband is greater than or equal to the first value, which can ensure the reliability of the measurement report obtained based on the partial resources of the target subband.

[0069] In some embodiments, some resources on a subband are obtained after puncturing all resources on the subband. It should be noted that all resources on a subband may include resources that cannot be measured (for example, resources allocated for uplink transmission, or resources used by a base station or a terminal to perform uplink-downlink conversion processing). Therefore, all resources on a subband may be punctured to leave resources that can be measured.

[0070] In some embodiments, the measurement report includes information determining the subband of the measurement report. By reporting the information determining the subband of the measurement report, the second node can perform subsequent resource scheduling and interference management. For example, when the subband corresponding to the measurement report has large interference, other subbands are selected for measurement. Alternatively, when the subband corresponding to the measurement report has small interference or meets communication requirements, service transmission is performed based on the subband.

[0071] In some embodiments, the method further includes: the first node reporting the uplink-downlink switching processing delay capability to the second node. By reporting the capability information related to the uplink-downlink switching processing delay that can indicate the first node, the second node can accurately and reliably configure / schedule measurement resources or service transmission.

[0072] It should be noted that on both sides of the inter-subband full-duplex symbol (SBFD symbol), the second node may perform conversion processing. At this time, the second node side can define a transition period indicator, but this indicator is only an indicator on the second node side, and the second node will not indicate the specific transition period size to the first node. Therefore, for the first node, the first node can only distinguish between SBFD symbols and non-subband full-duplex symbols (non-SBFD symbols). Because SBFD symbols can only be configured on continuous symbols with a time division duplexing (TDD) frame structure configured as D or F, for the first node, if downlink reception is performed on the SBFD symbol, then the non-SBFD symbol adjacent to the SBFD symbol may not be able to immediately perform uplink transmission due to the existence of conversion delay. Similarly, if uplink transmission is performed on the SBFD symbol, the first node may not be able to immediately perform downlink reception on the adjacent non-SBFD symbol. In addition, the first node not only needs to receive and send service data and control information, but also needs to perform various measurements for different purposes. Including channel estimation measurement, beam management measurement and mobility measurement. Among them, for mobility measurement, the first node must perform mobility measurement not only for the serving cell, but also for the adjacent cell. The adjacent cell may use the same SBFD symbol configuration as the serving cell, or may not support SBFD at all. In order to ensure that the first node can reliably perform downlink reception or uplink transmission or measurement on the SBFD symbol and its adjacent non-SBFD symbol, the first node can report the uplink and downlink switching processing delay capability to the second node.

[0073] In some embodiments, the uplink and downlink conversion processing delay can be the time interval required to wait between the first node performing consecutive receiving and sending operations; or the time interval from the moment when the uplink data sending or downlink data receiving operation is completed to the moment when it is able to prepare and start the data processing operation in the opposite direction (downlink reception or uplink transmission).

[0074] In some embodiments, the uplink and downlink conversion processing delay capability includes at least one of the following: no uplink and downlink conversion processing delay is required, uplink and downlink conversion processing delay is required, and uplink and downlink conversion processing delay is N time units. The time unit is milliseconds or microseconds or nanoseconds or subframes or time slots or orthogonal frequency division multiplexing (OFDM) symbols. N is a positive integer. No uplink and downlink conversion processing delay is required to indicate that the first node does not need an uplink and downlink conversion processing delay to complete service transmission or measurement. Uplink and downlink conversion processing delay is required to indicate that the first node needs an uplink and downlink conversion processing delay to complete service transmission or measurement. The uplink and downlink conversion processing delay is N time units to indicate the length of the uplink and downlink conversion processing delay adopted by the first node. In this way, it can be ensured that the first node can accurately and reliably complete service transmission or measurement.

[0075] In some embodiments, when the first node does not support receiving and sending operations on the same time unit, and the first node performs a sending operation on an inter-subband full-duplex symbol, the first node does not perform a receiving operation or a measuring operation on a second number of symbols adjacent to the inter-subband full-duplex symbol. The first node does not support receiving and sending operations on the same time unit, indicating that the first node may not support inter-subband full-duplex or is currently in a non-inter-subband full-duplex mode. At this time, when the first node performs a sending operation on an inter-subband full-duplex symbol, the first node may not be able to normally perform a receiving operation or a measuring operation on a second number of symbols adjacent to the inter-subband full-duplex symbol, and therefore, the first node may not perform a receiving operation or a measuring operation on a second number of symbols adjacent to the inter-subband full-duplex symbol. In this way, the first node can reduce the number of operations with low reliability and reduce resource consumption.

[0076] In some embodiments, when the first node does not support receiving and sending operations on the same time unit, and the first node performs a receiving operation or a measuring operation on an inter-subband full-duplex symbol, the first node does not perform a sending operation on a second number of symbols adjacent to the inter-subband full-duplex symbol. The first node does not support receiving and sending operations on the same time unit, indicating that the first node may not support inter-subband full-duplex or is currently in a non-inter-subband full-duplex mode. At this time, when the first node performs a receiving operation or a measuring operation on an inter-subband full-duplex symbol, the first node may not be able to normally perform a sending operation on the second number of symbols adjacent to the inter-subband full-duplex symbol. Therefore, the first node may not perform a sending operation on the second number of symbols adjacent to the inter-subband full-duplex symbol. In this way, the first node can reduce the number of operations with low reliability and reduce resource consumption.

[0077] In some embodiments, the second number is determined based on at least one of the following methods: based on the uplink and downlink switching processing delay capability indicated by the first node; based on a predefined method; based on configuration information of the second node. In this way, the second number can be flexibly determined in multiple ways.

[0078] Exemplarily, the second number may be determined based on the number of time units in the uplink and downlink switching processing delay capability indicated by the first node.

[0079] Exemplarily, the second number determined in a predefined manner may be 1 or 2.

[0080] In some embodiments, the configuration information of the second node is used to semi-statically configure the second number.

[0081] In some embodiments, the receiving operation includes the first node receiving traffic data or control information from a serving cell.

[0082] In some embodiments, the measuring operation includes at least one of the following:

[0083] The first node performs physical layer measurement on the serving cell;

[0084] The first node performs physical layer measurement on a neighboring cell of the serving cell;

[0085] The first node performs radio resource management measurement on the serving cell;

[0086] The first node performs radio resource management measurements on neighboring cells of the serving cell.

[0087] In some embodiments, the physical layer measurement includes at least one of the following: channel state information measurement (CSI measurement), beam management measurement (beam management measurement), layer 1 reference signal received power measurement (layer 1 reference signal received power measurement, L1-RSRP measurement), layer 1 signal to interference plus noise ratio measurement (layer 1 signal to interference plus noise ratio measurement, L1-SINR measurement), radio link monitoring measurement (radio link monitoring measurement, RLM measurement), beam failure detection measurement (beam failure detection measurement, BFD measurement), channel beam direction measurement (channel beam direction measurement, CBD measurement), and long-term measurement (long-term measurement, LTM measurement).

[0088] In some embodiments, the method further includes: the first node reports full-duplex capability to the second node; the full-duplex capability includes one of the following: supporting simultaneous execution of sending operations and receiving operations in the same time unit, and not supporting simultaneous execution of sending operations and receiving operations in the same time unit.

[0089] In some embodiments, the second node determines whether the first node has scheduling restrictions or measurement restrictions based on the full-duplex capability, such as the first node does not perform a receiving operation or a measuring operation on a second number of symbols adjacent to the inter-subband full-duplex symbol, or the first node does not perform a sending operation on a second number of symbols adjacent to the inter-subband full-duplex symbol. In this way, it can be ensured that the second node can perform appropriate scheduling / configuration based on the full-duplex capability of the first node.

[0090] In some embodiments, the first node or the second node may determine whether there is a scheduling restriction or a measurement restriction on the first node according to the transmission direction of the first node on the SBFD symbol.

[0091] Exemplarily, if the first node performs uplink transmission on the SBFD symbol, there is a scheduling restriction on downlink transmission on N symbols adjacent to the SBFD symbol, that is, the first node does not perform the transmission on the N symbols adjacent to the SBFD symbol.

[0092] Exemplarily, if the first node performs uplink transmission on the SBFD symbol, there are measurement restrictions on all same-frequency, different-frequency or different-system mobility measurements on the N symbols adjacent to the SBFD symbol, that is, the first node does not perform same-frequency, different-frequency or different-system mobility measurements on the N symbols adjacent to the SBFD symbol.

[0093] Exemplarily, if the first node performs downlink measurement on the SBFD symbol (which may be same-frequency, different-frequency or different-system mobility measurement), then there are scheduling restrictions on all uplink transmissions on the N symbols adjacent to the SBFD symbol, that is, the first node does not perform uplink transmission on the N symbols adjacent to the SBFD symbol.

[0094] For example, Figure 4 As shown, it is a schematic diagram of an inter-subband full-duplex symbol provided by an embodiment of the present disclosure, including two resource sets: flexible configuration resources on the inter-subband full-duplex symbol and flexible configuration resources not on the sub-band full-duplex symbol. Both resource sets include uplink resources, downlink resources and flexible configuration resources.

[0095] In some embodiments, the measurements include at least one of: radio resource management measurements, cross-link interference measurements, physical layer measurements.

[0096] In some embodiments, the measurement is a radio resource management measurement; when a time domain resource of the measurement resource partially or completely overlaps with a time domain resource of a full-duplex sub-band symbol, the measurement and the service transmission on the full-duplex sub-band symbol are performed based on the measurement resource, and one of the following is satisfied:

[0097] The priority of service transmission on the full-duplex sub-band symbol is higher than the priority of radio resource management measurement; or service transmission is performed on the overlapping resources, and radio resource management measurement is not performed on the overlapping resources and / or time domain resource units adjacent to the overlapping resources;

[0098] The priority of service transmission on full-duplex sub-band symbols is lower than the priority of radio resource management measurement; or radio resource management measurement is performed on overlapping resources and / or time domain resource units adjacent to overlapping resources, and service transmission is not performed on overlapping resources.

[0099] It should be noted that the reference signal (RS) for radio resource management measurement needs to be configured in the measurement object (MO). Exemplarily, the second node may configure the reference signal to the first node through radio resource control (RRC) signaling. The configuration content may include time domain configuration information and frequency domain configuration information of the reference signal for mobility management for a specific frequency point or a specific radio access technology. The time domain configuration information may include inter-subband full-duplex symbols and the time domain position and period of inter-subband full-duplex symbols. In the case where there is a partial or complete overlap between the reference signal for radio resource management measurement and the appetite configuration of the inter-subband full-duplex symbol, how to perform radio resource management measurement and service transmission or control information transmission can be determined based on the above-mentioned priority.

[0100] In some embodiments, when the priority of service transmission on full-duplex subband symbols is higher than the priority of wireless resource management measurements, service transmission and / or control information transmission can be performed on overlapping resources, and wireless resource management measurements are not performed on overlapping resources and / or time domain resource units adjacent to overlapping resources.

[0101] In some embodiments, when the priority of service transmission on full-duplex subband symbols is lower than the priority of wireless resource management measurements, wireless resource management measurements can be performed on overlapping resources and / or time domain resource units adjacent to overlapping resources, and service transmission and / or control information transmission is not performed on overlapping resources.

[0102] In some embodiments, the number of adjacent time domain resource units of overlapping resources may be N2, where N2 is a positive integer.

[0103] In some embodiments, the measurement is a cross-link interference measurement.

[0104] It should be noted that in a dynamic time division duplexing system (dynamic TDD system) or a sub-band full duplex system (SBFD system), cross-link interference measurement can be applied to resolve interference between uplink and downlink transmissions. However, in the current scenario where CLI measurement is applied, uplink and downlink transmissions are both from the same system, such as a new wireless system or a long-term evolution system. For future deployments, there may be coexistence of different systems in multiple spatial dimensions, such as the coexistence of a new radio terrestrial network system (NR TN system) and a new radio non-terrestrial network system (NR NTN system). At this point, for terminals that are provided with wireless communication services by different systems, whether they are located in the same cell or in different cells, they may be subject to uplink and downlink interference from each other.

[0105] For example, Figure 5 As shown, user equipment 1 is served by a new wireless terrestrial network system. User equipment 2 is served by a new wireless non-terrestrial network system, such as a satellite system. When user equipment 1 and user equipment 2 are physically close to each other, the time division duplex frame structures configured for the two terminals may be the same or different in order to avoid interference between them. Figure 5Take the same frame structure as an example. The frame structure of user equipment 1 includes 4 cross-link interference measurement resources. User equipment 2 is served by the new wireless non-terrestrial network system. Since the link transmission delay of the new wireless non-terrestrial network system is very large, the timing advance (TA) of user equipment 2 is relatively large. Then the actual uplink transmission time domain resources of user equipment 2 may overlap with the downlink transmission time domain resources or the flexible configuration time domain resources of user equipment 1, so that the uplink transmission of user equipment 2 will cause greater interference to the downlink reception of user equipment 1. Then the interference coordination technology needs to be applied to this scenario. Cross-link interference measurement resources can be configured for user equipment 1, instructing user equipment 1 to perform cross-link interference measurement on the cross-link interference measurement resources, and feeding back the cross-link interference measurement results to the serving base station, so that the serving base station understands the interference situation of user equipment 1 on different cross-link interference measurement resources, thereby avoiding strong interference in subsequent time-frequency resource scheduling to achieve interference coordination. The service base station of user equipment 1 does not know the size of the link timing advance of user equipment 2. By configuring multiple sets of cross-link interference measurement resources for user equipment 1 and configuring how to feedback the cross-link interference measurement results, the service base station estimates the size of the timing advance of user equipment 2 by receiving the cross-link interference measurement results fed back by user equipment 1, so as to avoid interference when subsequently scheduling users in this cell, such as user equipment 1. At this time, the measurement resources may include at least one of the cross-link interference measurement resources. The cross-link interference measurement resources satisfy at least one of the following: the cross-link interference measurement resources include multiple discrete time domain resource units; the cross-link interference measurement resources include one time domain resource unit or multiple continuous time domain resource units and multiple cross-link interference measurement resources constitute a cross-link interference measurement resource set. Among them, the discrete time domain resource units can be measured at different time points, which can cover various possible moments of interference, so as to capture the interference situation more comprehensively and improve the detection accuracy of interference. In addition, it can also enable the second node to infer the timing advance based on the measurement report to ensure the reliability of communication.

[0106] For example, Figure 6 As shown, it is a schematic diagram of a time-domain discrete time-domain resource unit provided in an embodiment of the present disclosure, including cross-link interference measurement resource 1, cross-link interference measurement resource 2, and cross-link interference measurement resource 3.

[0107] For example, Figure 7 As shown, it is a schematic diagram of a cross-link interference measurement resource set provided by an embodiment of the present disclosure, including a cross-link interference measurement resource set 1, a cross-link interference measurement resource set 2, and a cross-link interference measurement resource set 3.

[0108] In some embodiments, the above measurement results may include at least one of the following: reference signal receiving power (RSRP); signal-to-interference plus noise ratio (SINR); reference signal receiving quality (RSRQ); received signal strength indication (RSSI).

[0109] In some embodiments, when the cross-link interference measurement resource includes a plurality of discrete time domain resource units, the measurement report includes at least one of the following:

[0110] The index of the cross-link interference measurement resource corresponding to the maximum measurement result value and the index of the cross-link interference measurement resource corresponding to the minimum measurement result value;

[0111] the maximum measurement result value and the minimum measurement result value, or the levels corresponding to the maximum measurement result value and the minimum measurement result value respectively;

[0112] The starting or ending domain resource of the cross-link interference measurement resource corresponding to the maximum measurement result value, and the starting or ending domain resource of the cross-link interference measurement resource corresponding to the minimum measurement result value.

[0113] It should be understood that the index of the cross-link interference measurement resource corresponding to the maximum measurement result value and the index of the cross-link interference measurement resource corresponding to the minimum measurement result value can indicate which resource units suffer the strongest and weakest interference among many discrete time domain resource units.

[0114] It should be understood that the maximum measurement result value and the minimum measurement result value, or the levels corresponding to the maximum measurement result value and the minimum measurement result value, can directly reflect the interference intensity. The second node can intuitively understand the severity range of the interference through these values, so that the second node can perform resource allocation and scheduling strategy formulation.

[0115] It should be understood that the starting or ending domain resources of the cross-link interference measurement resources corresponding to the maximum measurement result value and the starting or ending domain resources of the cross-link interference measurement resources corresponding to the minimum measurement result value can enable the second node to determine the location of the resources where interference exists.

[0116] It should be understood that by specifying the content of the measurement report reported by the first node, the second node can be flexibly and reliably assisted to perform subsequent scheduling / configuration / interference avoidance based on the measurement report.

[0117] In some embodiments, when there are multiple maximum measurement result values ​​obtained by measurement, the maximum measurement result value included in the measurement report is the maximum measurement result value of the time domain resource that is closest to the front among the multiple maximum measurement result values, or the maximum measurement result value of the time domain resource that is closest to the back among the multiple maximum measurement result values. The maximum measurement result value of the time domain resource that is closest to the front can assist the second node in determining the result of the earliest occurrence of strong interference, so that the second node can respond to the interference quickly. The maximum measurement result value of the time domain resource that is closest to the back can assist the second node in determining the result of the last occurrence of strong interference, so that the second node can determine the duration of the interference.

[0118] In some embodiments, when there are multiple minimum measurement result values ​​obtained by measurement, the minimum measurement result value included in the measurement report is the minimum measurement result value for the earliest time domain resource among the multiple minimum measurement result values, or is the minimum measurement result value for the latest time domain resource among the multiple minimum measurement result values. The earliest minimum measurement result value for the time domain resource can assist the second node in determining the earliest result of weak interference, so that the second node can quickly allocate the service with weak anti-interference ability to a reliable position. The latest minimum measurement result value for the time domain resource can assist the second node in determining the latest result of weak interference, so that the second node can determine the allocatable interval of the service with weak anti-interference ability.

[0119] In some embodiments, when the cross-link interference measurement resource includes one time domain resource unit or multiple consecutive time domain resource units, and the multiple cross-link interference measurement resources constitute a cross-link interference measurement resource set, the measurement report includes at least one of the following:

[0120] The index of the cross-link interference measurement resource set having the largest difference in measurement result values;

[0121] the maximum measurement result value and the minimum measurement result value measured on the cross-link interference measurement resource set with the largest measurement result value difference; or the levels corresponding to the maximum measurement result value and the minimum measurement result value respectively;

[0122] The number of time domain resources between the start or end time domain resource corresponding to the maximum measurement result value and the start or end time domain resource corresponding to the minimum measurement result value.

[0123] It should be understood that the index of the cross-link interference measurement resource set with the largest difference in measurement result values ​​can enable the second node to determine the area with the most significant interference change, so that the second node can focus on interference analysis and processing in this area.

[0124] It should be understood that the maximum measurement result value and the minimum measurement result value measured on the cross-link interference measurement resource set with the largest measurement result value difference can enable the second node to intuitively determine the range of interference intensity changes in the area where the interference changes most significantly. The levels corresponding to the maximum measurement result value and the minimum measurement result value can simplify the interference intensity information, making it easier for the second node to make a quick decision.

[0125] It should be understood that the number of time domain resources between the starting or ending time domain resources corresponding to the maximum measurement result value and the starting or ending time domain resources corresponding to the minimum measurement result value can indicate the quantitative result of the interference distribution in the time domain, so that the second node can perform in-depth analysis and processing in the time dimension.
