[0034] The technical solutions of this disclosure will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0035] It should be noted that, in this disclosure, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "exemplarily" or "for example" in this disclosure should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.

[0036] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0037] In the description of this disclosure, unless otherwise stated, " / " means "or," for example, A / B can mean A or B. "And / or" in this document is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Furthermore, "at least one" means one or more, and "more than one" means two or more.

[0038] In communication networks, in order to improve spectrum utilization efficiency and reduce transmission latency, terminals and base stations can communicate via inter-subband full-duplex communication.

[0039] During communication, terminals may experience uplink and downlink interference from their own cell or neighboring cells. To ensure the reliability of inter-subband full-duplex communication, measurements need to be performed at the terminal side so that the base station can modulate the communication based on the measurement results. Therefore, a reliable method for performing measurements related to inter-subband full-duplex communication is urgently needed.

[0040] To address the aforementioned technical problems, this disclosure provides a communication method in which configuration information indicating measurement resources reflects relevant information about measurements that a second node expects a first node to perform. Therefore, by receiving the configuration information indicating measurement resources, the first node can reliably perform measurements based on the measurement resources, enabling the second node to estimate the interference experienced by the first node on time-frequency resources from its own cell or neighboring cells. This allows the second node to determine which time-frequency resources the first node experiences the most interference, enabling it to avoid interference when scheduling / configuring the first node's service transmissions. This improves communication reliability and enhances the performance of the communication system.

[0041] The communication method provided in this disclosure can be applied to systems with various communication standards. For example, the systems to which the communication method provided in this disclosure is applicable include, but are not limited to, long-term evolution (LTE) systems, various versions based on LTE evolution, 5th generation mobile communication technology (5G) systems, future mobile communication networks (e.g., 6G mobile communication networks), or multiple converged communication systems. Furthermore, the communication method provided in this disclosure can also be applied to future-oriented communication systems.

[0042] For example, the above communication method can be applied to the communication system shown in FIG1. ​​As shown in FIG1, the communication system includes: a first node 101 and a second node 102.

[0043] Here, the first node 101 is used to receive configuration information from the second node 102 for indicating measurement resources; or, to perform measurements based on the measurement resources and obtain a measurement report; or, to send a measurement report to the second node 102.

[0044] The second node 102 is used to send configuration information for indicating measurement resources to the first node 101; or, it is used to receive measurement reports sent by the first node 101.

[0045] In some embodiments, the first node 101 can be a terminal.

[0046] In some embodiments, the second node 102 may be a base station.

[0047] In some embodiments, the terminal can be a device with wireless transceiver capabilities, which can be deployed on land, including indoors or outdoors, handheld, wearable, or vehicle-mounted; it can also be deployed on water (such as on ships); and it can also be deployed in the air (e.g., on airplanes, balloons, and satellites). The terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, virtual reality (VR) terminal, augmented reality (AR) terminal, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical care, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, wireless terminal in smart home, etc. The embodiments of this application do not limit the application scenarios. The term "terminal" can sometimes also refer to 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 device, UE agent, or UE device, etc., but the embodiments of this application do not limit this to these terms.

[0048] In some embodiments, the base station may be a base station in Long Term Evolution (LTE), Long Term Evolution Advanced (LTEA), or an evolved Node B (eNB or eNodeB), a base station device in a 5G network, or a base station in a future communication system. The base station may include various macro base stations, micro base stations, femtocell base stations, wireless remote extensions, reconfigurable intelligent surfaces (RISs), routers, wireless fidelity (WIFI) devices, or various network-side devices such as primary cells and secondary cells.

[0049] It should be noted that Figure 1 is only an exemplary framework diagram, and the number of devices included in Figure 1 and the names of each device are not limited.

[0050] The application scenarios of the embodiments disclosed herein are not limited. The system architecture and business scenarios described in the embodiments of this disclosure are for the purpose of more clearly illustrating the technical solutions of the embodiments of this disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of this disclosure. As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of this disclosure are also applicable to similar technical problems.

[0051] The communication method provided in the embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0052] The communication method provided in this disclosure can be applied to the first node 101 in the communication system shown in FIG1. ​​FIG2 shows a schematic flowchart of a communication method, which includes the following steps S201-S203:

[0053] S201, Receive configuration information from the second node for indicating measurement resources.

[0054] It should be noted that in a full-duplex sub-band 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 can perform measurements (or cross-link interference measurements) on the one or more sets of measurement resources.

[0055] Here, when cross-link interference measurement is possible, the interference experienced by the first node on time-frequency resources from its own cell or neighboring cells can be estimated. This allows identification of which time-frequency resources the first node experiences the strongest interference, enabling the second node to avoid interference when scheduling / configuring the first node's service transmissions. This improves communication reliability and enhances the performance of the communication system.

[0056] For example, Figure 3 illustrates a schematic diagram of cross-link interference measurement resource distribution provided in an embodiment of this disclosure. Here, it includes the currently active (or usable) downlink portion bandwidth (BWP), two downlink subbands, one uplink 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 punched portion, and resource block set 2.

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

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

[0059] S202. Perform measurements based on measurement resources 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 measurement resources reflects relevant information about the measurements the second node expects the first node to perform. Therefore, by receiving this configuration information, the first node can reliably perform measurements based on these resources, enabling the second node to estimate the interference the first node experiences from its own cell or neighboring cells on time-frequency resources. This allows the second node to determine which time-frequency resources the first node experiences the most interference, enabling it to mitigate interference when scheduling / configuring the first node's service transmissions. This improves communication reliability and enhances the performance of the communication system.

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

[0063] Here, the statement that measurement resources can span multiple discontinuous subbands can be understood as: measurement resources include part or all of the resources in each of the multiple discontinuous subbands.

[0064] In one example, the measurement report meets one of the following criteria:

[0065] 1-1. Each of the multiple sub-bands corresponds to a measurement report.

[0066] Here, when multiple sub-bands each correspond to a measurement report, more detailed measurement results can be reported, which can adapt to scenarios with high precision requirements.

[0067] 1-2. Multiple sub-bands correspond to one measurement report.

[0068] Here, multiple sub-bands correspond to one measurement report, which can reduce signaling overhead and adapt to scenarios with high reporting efficiency requirements.

[0069] In this embodiment of the disclosure, since the measurement report can satisfy one of the following conditions, namely, the ability to flexibly select the appropriate reporting method, it can meet the needs of different scenarios.

[0070] In some embodiments, each of the multiple sub-bands corresponds to a measurement report.

[0071] Here, the measurement report for a subband is obtained based on some or all of the resources on that subband. The number of physical resource blocks included in the partial resources is greater than or equal to a first value.

[0072] On the one hand, the measurement report for each sub-band is determined based on the resources of that sub-band, enabling independent measurement of each sub-band and providing reliable measurement results for that sub-band. On the other hand, if resources on a sub-band are punctured or occupied by other transmissions, the remaining resources of a sub-band can be used as measurement resources, and the measurement report for that sub-band can be determined based on these resources, thus adapting to more scenarios.

[0073] In addition, the number of physical resource blocks included in the portion of 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 ensures the reliability of the measurement results.

[0074] In some embodiments, multiple sub-bands may correspond to a single measurement report.

[0075] Here, the measurement report also meets one of the following criteria:

[0076] 1-3. The measurement report is based on the joint determination of resources across multiple subbands.

[0077] Here, based on the measurement report jointly determined by resources on multiple sub-bands, the overall interference situation corresponding to multiple sub-bands can be determined by actually measuring the resources on multiple sub-bands.

[0078] 1-4. Measurement reports are based on some or all of the resources in the target subband among multiple subbands.

[0079] Here, the measurement report is determined based on some or all of the resources on the target subband among multiple subbands. The overall interference situation of multiple subbands can be reflected by the measurement results corresponding to the representative target subband.

[0080] In some embodiments, where the measurement report is determined based on some or all of the resources on a target subband among multiple subbands, the number of physical resource blocks included in the partial resources is greater than or equal to a first value.

[0081] Since the reliability of the measurement may be low when the number of resources involved 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.

[0082] In some embodiments, the target subband is the subband with the most physical resource blocks among multiple subbands, and the number of physical resource blocks included in a portion of the resources is greater than or equal to a first value.

[0083] Here, the target subband is the subband with the most physical resource blocks among multiple subbands. This ensures the representativeness of the target subband and guarantees that the measurement report based on the target subband can reflect the overall interference situation of multiple subbands. The number of physical resource blocks included in the portion of resources used for measurement on the target subband is greater than or equal to the first value, which ensures the reliability of the measurement report based on a portion of the resources of the target subband.

[0084] In some embodiments, a portion of the resources on a subband is obtained by performing a punching process on all the resources on that subband.

[0085] It should be noted that all resources on a subband may include resources that cannot be measured (e.g., resources allocated for uplink transmission, or resources used by the second or first node to perform uplink / downlink conversion). Therefore, all resources on a subband can be punctured, retaining only those resources that can be measured.

[0086] In some embodiments, the measurement report includes information identifying the subband of the measurement report. By reporting this information, the second node can perform subsequent resource scheduling and interference management. For example, if the subband corresponding to the measurement report has significant interference, another subband can be selected for measurement. Alternatively, if the subband corresponding to the measurement report has low interference or meets communication requirements, service transmission can be based on that subband.

[0087] In some embodiments, the method further includes: the first node reporting uplink / downlink switching processing latency capabilities to the second node. By reporting capability information related to uplink / downlink switching processing latency that indicates the first node, the second node can accurately and reliably configure / schedule measurement resources or service transmissions.

[0088] It should be noted that the second node may perform transition processing on both sides of the inter-subband full-duplex symbol (SBFD symbol). In this case, the second node can define a transition period indicator, but this indicator is only for the second node; the second node will not indicate the specific size of the transition period to the first node. Therefore, the first node can only distinguish between SBFD symbols and non-SBFD symbols. This is because SBFD symbols can only be configured on consecutive symbols with a time division duplex (TDD) frame structure configured as D or F. For the first node, if downlink reception is performed on an SBFD symbol, uplink transmission may not be immediately performed on the adjacent non-SBFD symbol due to transition delays.

[0089] Similarly, if uplink transmission is performed on an SBFD symbol, the first node may not be able to immediately perform downlink reception on an adjacent non-SBFD symbol. Furthermore, the first node not only needs to receive and transmit service data and control information, but also needs to perform various measurements for different purposes, such as channel estimation measurements, beam management measurements, and mobility measurements.

[0090] Here, for mobility measurement, the first node must perform mobility measurements not only on the serving cell but also on neighboring cells. Neighboring cells may use the same SBFD symbol configuration as the serving cell, or they may not support SBFD. Therefore, to ensure that the first node can reliably perform downlink reception, uplink transmission, or measurement on SBFD symbols and their adjacent non-SBFD symbols, the first node can report uplink / downlink switching processing latency capabilities to the second node.

[0091] In some embodiments, the uplink / downlink switching processing delay can be the time interval that the first node needs to wait between performing consecutive receive and transmit operations, or the time interval between the end of the uplink data transmission or downlink data reception operation and the moment when it is ready to start the reverse direction (downlink reception or uplink transmission) data processing operation.

[0092] In some embodiments, uplink / downlink switching processing latency capability includes at least one of the following:

[0093] 2-1. No uplink / downlink conversion processing delay is required.

[0094] Here, "no uplink / downlink conversion processing delay" is used to indicate that the first node can complete service transmission or measurement without uplink / downlink conversion processing delay.

[0095] 2-2. Uplink and downlink conversion processing requires latency.

[0096] Here, the uplink / downlink conversion processing delay is needed to indicate the uplink / downlink conversion processing delay required by the first node to complete service transmission or measurement.

[0097] 2-3. The uplink / downlink conversion processing delay is N time units.

[0098] Here, the uplink / downlink conversion processing delay is defined as N time units, indicating the length of the uplink / downlink conversion processing delay used by the first node. This ensures that the first node can accurately and reliably complete service transmission or measurement. The time unit can be milliseconds, microseconds, nanoseconds, subframes, time slots, or orthogonal frequency division multiplexing (OFDM) symbols. N is a positive integer.

[0099] In some embodiments, if the first node does not support performing receive and transmit operations in the same time unit, and the first node performs transmit operations on inter-subband full-duplex symbols, the first node does not perform receive or measurement operations on a second number of symbols adjacent to the inter-subband full-duplex symbols.

[0100] Here, the first node does not support performing receive and transmit 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. In this case, if the first node performs a transmit operation on an inter-subband full-duplex symbol, it may be unable to perform receive or measurement operations normally on the second number of symbols adjacent to the inter-subband full-duplex symbol. Therefore, the first node can choose not to perform receive or measurement operations on the second number of symbols adjacent to the inter-subband full-duplex symbol. This reduces the number of operations with lower reliability performed by the first node, thus reducing resource consumption.

[0101] In some embodiments, if the first node does not support performing receive and transmit operations in the same time unit, and the first node performs receive or measurement operations on inter-subband full-duplex symbols, the first node does not perform transmit operations on a second number of symbols adjacent to the inter-subband full-duplex symbols.

[0102] Here, the first node does not support performing receive and transmit 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. In this case, if the first node performs a receive or measurement operation on an inter-subband full-duplex symbol, it may be unable to correctly perform a transmit operation on the second number of symbols adjacent to the inter-subband full-duplex symbol. Therefore, the first node can choose not to perform transmit operations on the second number of symbols adjacent to the inter-subband full-duplex symbol. This reduces the number of operations with lower reliability performed by the first node, thus reducing resource consumption.

[0103] In some embodiments, the second quantity is determined based on at least one of the following methods:

[0104] 3-1. Determination of uplink / downlink switching processing latency based on the indication of the first node.

[0105] For example, the second quantity can be determined based on the number of time units in the uplink / downlink conversion processing latency capability indicated by the first node.

[0106] 3-2. Determined based on predefined methods.

[0107] For example, the second quantity determined by the predefined method can be 1 or 2.

[0108] 3-3. Determine the configuration information based on the second node.

[0109] In some embodiments, the configuration information of the second node is used to semi-statically configure the second quantity.

[0110] In this way, the second quantity can be determined flexibly in a variety of ways.

[0111] In some embodiments, the receiving operation includes the first node receiving service data or control information from the serving cell.

[0112] In some embodiments, the measurement operation includes at least one of the following:

[0113] 4-1. The first node performs physical layer measurements on the serving cell.

[0114] 4-2. The first node performs physical layer measurements on the neighboring cells of the serving cell.

[0115] 4-3. The first node performs radio resource management measurements on the serving cell.

[0116] 4-4. The first node performs radio resource management measurements on the neighboring cells of the serving cell.

[0117] In some embodiments, physical layer measurements include at least one of the following: channel state information measurement (CSI measurement), beam management measurement, layer 1 reference signal received power measurement (L1-RSRP measurement), layer 1 signal to interference plus noise ratio measurement (L1-SINR measurement), radio link monitoring measurement (RLM measurement), beam failure detection measurement (BFD measurement), channel beam direction measurement (CBD measurement), and long-term measurement (LTM measurement).

[0118] In some embodiments, the method provided in this disclosure further includes: the first node reporting full-duplex capability to the second node.

[0119] Here, full-duplex capability includes one of the following: supporting simultaneous transmission and reception operations in the same time unit, or not supporting simultaneous transmission and reception operations in the same time unit.

[0120] In some embodiments, the second node determines, based on its full-duplex capability, whether the first node has scheduling or measurement restrictions, such as the first node not performing receive or measurement operations on a second number of symbols adjacent to inter-subband full-duplex symbols, or the first node not performing transmit operations on a second number of symbols adjacent to inter-subband full-duplex symbols. This ensures that the second node can perform appropriate scheduling / configuration based on the first node's full-duplex capability.

[0121] In some embodiments, the first node or the second node can determine whether the first node has scheduling or measurement restrictions based on the transmission direction of the first node on the SBFD symbol.

[0122] For example, if the first node performs uplink transmission on the SBFD symbol, then there is a scheduling restriction on downlink transmission on the N symbols adjacent to the SBFD symbol, that is, the first node does not perform transmission on the N symbols adjacent to the SBFD symbol.

[0123] For example, if the first node performs uplink transmission on the SBFD symbol, then there are measurement restrictions on all same-frequency, different-frequency, or different-system mobility measurements on the N adjacent symbols of the SBFD symbol, that is, the first node does not perform same-frequency, different-frequency, or different-system mobility measurements on the N adjacent symbols of the SBFD symbol.

[0124] For example, if the first node performs downlink measurements (which can be same-frequency, different-frequency, or different-system mobility measurements) on the SBFD symbol, 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 transmissions on the N symbols adjacent to the SBFD symbol.

[0125] For example, as shown in FIG4, a schematic diagram of an inter-subband full-duplex symbol provided by an embodiment of the present disclosure includes two resource sets: one where flexible configuration resources are on the inter-subband full-duplex symbol and the other where flexible configuration resources are not on the inter-subband full-duplex symbol. Both resource sets include uplink resources, downlink resources, and flexible configuration resources.

[0126] In some embodiments, the measurement includes at least one of the following: radio resource management measurement, cross-link interference measurement, and physical layer measurement.

[0127] In some embodiments, the measurement is a radio resource management measurement. Where the time-domain resources of the measurement resource partially or completely overlap with the time-domain resources of a full-duplex subband symbol, the measurement and service transmission on the full-duplex subband symbol are performed based on the measurement resource, satisfying one of the following:

[0128] 5-1. Service transmission on full-duplex subband symbols has a higher priority than radio resource management measurements; or service transmission is performed on overlapping resources, and radio resource management measurements are not performed on overlapping resources and / or adjacent time-domain resource units.

[0129] 5-2. Service transmission on full-duplex subband symbols has a lower priority than radio resource management measurement; or radio resource management measurement is performed on overlapping resources and / or adjacent time-domain resource units, and service transmission is not performed on overlapping resources.

[0130] It should be noted that the reference signal (RS) for wireless resource management measurements needs to be configured in the measurement object (MO).

[0131] For example, the second node can configure a reference signal to the first node via radio resource control (RRC) signaling.

[0132] Here, the configuration content may include time-domain and frequency-domain configuration information for reference signals used for mobility management at specific frequency points or for specific radio access technologies. The time-domain configuration information may include the time-domain position and period of inter-subband full-duplex symbols.

[0133] In cases where there is partial or complete overlap between the reference signal for radio resource management measurements and the configuration of full-duplex symbols between subbands, the method for performing radio resource management measurements and service transmissions or control information transmissions can be determined based on the aforementioned priorities.

[0134] In some embodiments, where the priority of service transmission on a full-duplex subband symbol is higher than the priority of radio resource management measurement, service transmission and / or control information transmission may be performed on overlapping resources, and radio resource management measurement may not be performed on overlapping resources and / or adjacent time-domain resource units of overlapping resources.

[0135] In some embodiments, where the priority of service transmission on a full-duplex subband symbol is lower than the priority of radio resource management measurement, radio resource management measurement may be performed on overlapping resources and / or time-domain resource units adjacent to the overlapping resources, and service transmission and / or control information transmission may not be performed on the overlapping resources.

[0136] In some embodiments, the number of adjacent temporal resource units of overlapping resources can be N2. N2 is a positive integer.

[0137] In some embodiments, the measurement is a cross-link interference measurement.

[0138] It should be noted that in Dynamic Time Division Duplex (TDD) systems or Sub-Band Full Duplex (SBFD) systems, cross-link interference (CLI) measurements can be used to address interference between uplink and downlink transmissions. However, in current CLI measurement scenarios, both uplink and downlink transmissions originate from the same system, such as a new radio system or a Long Term Evolution (LTE) system.

[0139] Future deployments may face the coexistence of different systems across multiple spatial dimensions. For example, the New Radio Terrestrial Network (NRTN) system may coexist with the New Radio Non-Terrestrial Network (NRNTN). In this situation, terminals providing wireless communication services through different systems, whether located in the same cell or different cells, may experience uplink and downlink interference from each other.

[0140] For example, as shown in Figure 5, User Equipment 1 may be served by a new wireless terrestrial network system. User Equipment 2 may be served by a new wireless non-terrestrial network system, such as a satellite system.

[0141] When User Equipment 1 and User Equipment 2 are physically close, to avoid interference, the time-division duplex frame structures configured for these two user equipments may be the same or different. Figure 5 uses the same frame structure as an example. The frame structure of User Equipment 1 includes four cross-link interference measurement resources. User Equipment 2 is served by a new wireless non-terrestrial network system. Due to the large link transmission delay of the new wireless non-terrestrial network system, the timing advance (TA) of User Equipment 2 is large.

[0142] Furthermore, the actual uplink transmission time domain resources of User Equipment 2 may overlap with the downlink transmission time domain resources or flexibly configurable time domain resources of User Equipment 1. This can cause significant interference to the downlink reception of User Equipment 1 due to the uplink transmission of User Equipment 2. Therefore, interference coordination techniques are needed in this scenario. Thus, cross-link interference measurement resources can be configured for User Equipment 1, instructing it to perform cross-link interference measurements on these resources and feeding back the results to the serving base station. This allows the serving base station to understand the interference situation of User Equipment 1 on different cross-link interference measurement resources, thereby avoiding strong interference in subsequent time-frequency resource scheduling and achieving interference coordination.

[0143] Since the serving base station of User Equipment 1 does not know the timing advance of User Equipment 2's link, it can configure multiple sets of cross-link interference measurement resources for User Equipment 1 and configure how to feed back the cross-link interference measurement results. By receiving the cross-link interference measurement results fed back by User Equipment 1, the serving base station can estimate the timing advance of User Equipment 2, and thus perform interference avoidance when scheduling users in the cell (e.g., User Equipment 1) in the future.

[0144] At this point, the measurement resources may include cross-link interference measurement resources. Cross-link interference measurement resources must satisfy at least one of the following:

[0145] 6-1. Cross-link interference measurement resources include multiple discrete time-domain resource units.

[0146] 6-2. Cross-link interference measurement resources include one time-domain resource unit or multiple consecutive time-domain resource units, and multiple cross-link interference measurement resources form a cross-link interference measurement resource set.

[0147] Here, discrete time-domain resource units can be measured at different points in time, covering various possible times when interference may occur, thus capturing interference more comprehensively and improving the accuracy of interference detection. In addition, it can also enable the second node to infer timing advance based on the measurement report, ensuring the reliability of communication.

[0148] For example, as shown in FIG6, a schematic diagram of a time-domain discrete time-domain resource unit provided in an embodiment of the present disclosure is provided, including cross-link interference measurement resource 1, cross-link interference measurement resource 2, and cross-link interference measurement resource 3.

[0149] For example, as shown in FIG7, a schematic diagram of a cross-link interference measurement resource set provided in an embodiment of the present disclosure is provided, including cross-link interference measurement resource set 1, cross-link interference measurement resource set 2, and cross-link interference measurement resource set 3.

[0150] 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), and received signal strength indication (RSSI).

[0151] In some embodiments, where the cross-link interference measurement resource comprises multiple discrete time-domain resource units, the measurement report includes at least one of the following:

[0152] 7-1. 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.

[0153] Here, the indexes of the cross-link interference measurement resources corresponding to the maximum and minimum measurement results can indicate which resource units among numerous discrete time-domain resource units have suffered the strongest and weakest interference.

[0154] 7-2. The maximum and minimum measurement result values, or the corresponding levels for the maximum and minimum measurement result values.

[0155] Here, the maximum and minimum measurement results, or the corresponding levels for each, directly reflect the intensity of the interference. This allows the second node to intuitively understand the severity range of the interference through these values, enabling it to formulate resource allocation and scheduling strategies.

[0156] 7-3. 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.

[0157] Here, the start or end domain resources of the cross-link interference measurement resource corresponding to the maximum measurement result value, and the start or end domain resources of the cross-link interference measurement resource corresponding to the minimum measurement result value, enable the second node to determine the location of the resource where interference exists.

[0158] In this embodiment of the disclosure, by specifying the content of the measurement report reported by the first node, the second node can be flexibly and reliably assisted in performing subsequent scheduling / configuration / interference avoidance based on the measurement report.

[0159] In some embodiments, when there are multiple maximum measurement result values, the maximum measurement result value included in the measurement report is either the maximum measurement result value with the longest time domain resource among the multiple maximum measurement result values, or the maximum measurement result value with the longest time domain resource among the multiple maximum measurement result values.

[0160] Here, the largest measurement result of the earliest time-domain resource helps the second node determine the earliest occurrence of strong interference, enabling the second node to respond quickly to the interference. The largest measurement result of the latest time-domain resource helps the second node determine the last occurrence of strong interference, enabling the second node to determine the duration of the interference.

[0161] In some embodiments, when there are multiple minimum measurement result values, the minimum measurement result value included in the measurement report is either the minimum measurement result value with the earliest time domain resource among the multiple minimum measurement result values, or the minimum measurement result value with the latest time domain resource among the multiple minimum measurement result values.

[0162] Here, the earliest minimum measurement result of the time-domain resource helps the second node determine the earliest occurrence of weak interference, enabling the second node to quickly allocate services with weak anti-interference capabilities to reliable locations. The latest minimum measurement result of the time-domain resource helps the second node determine the last occurrence of weak interference, enabling the second node to determine the allocatable range for services with weak anti-interference capabilities.

[0163] In some embodiments, when the cross-link interference measurement resources include one or more 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:

[0164] 8-1. Index of the cross-link interference measurement resource set with the largest numerical difference in measurement results.

[0165] Here, the index of the cross-link interference measurement resource set with the largest numerical difference in the measurement results enables the second node to identify the region with the most significant interference changes, allowing the second node to focus on interference analysis and processing in that region.

[0166] 8-2. The maximum and minimum measurement result values ​​measured on the cross-link interference measurement resource set with the largest difference in measurement result values; or the corresponding levels of the maximum and minimum measurement result values.

[0167] Here, the maximum and minimum measurement values ​​obtained from the cross-link interference measurement resource set with the largest difference in measurement results allow the second node to intuitively determine the range of interference intensity variation in the region where interference changes are most significant. The levels corresponding to the maximum and minimum measurement values ​​simplify the interference intensity information, facilitating rapid decision-making by the second node.

[0168] 8-3. The number of time-domain resources between the start or end domain resources corresponding to the maximum measurement result value and the start or end domain resources corresponding to the minimum measurement result value.

[0169] Here, the number of time-domain resources between the start or end domain resources corresponding to the maximum measurement result value and the start or end domain resources corresponding to the minimum measurement result value can indicate the quantification result of the interference distribution in the time domain, which facilitates the second node to perform in-depth analysis and processing in the time dimension.
