The core network may include, for example, at least one of the Evolved Packet Core (EPC), the 5G Core Network (5GCN), and the Next Generation Core (NGC).

In some embodiments, the technical solution of the present disclosure may be applicable to the Open RAN architecture. In this case, the interfaces between access network devices or within access network devices involved in the embodiments of the present disclosure may become internal interfaces of Open RAN, and the processes and information interactions between these internal interfaces may be implemented through software or programs.

In some embodiments, the access network device may be composed of a centralized unit (central unit, CU) and a distributed unit (distributed unit, DU), wherein the CU may also be called a control unit (control unit). The CU-DU structure may be used to split the protocol layer of the access network device, with some functions of the protocol layer being centrally controlled by the CU, and the remaining part or all of the functions of the protocol layer being distributed in the DU, and the DU being centrally controlled by the CU, but not limited to this.

It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. A person of ordinary skill in the art can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or part of the subject, but are not limited thereto. The subjects shown in FIG1 are examples, and the communication system may include all or part of the subjects in FIG1 , or may include other subjects other than FIG1 , and the number and form of the subjects are arbitrary, and the subjects may be physical or virtual, and the connection relationship between the subjects is an example, and the subjects may be connected or disconnected, and the connection may be in any manner, and may be a direct connection or an indirect connection, and may be a wired connection or a wireless connection.

The embodiments of the present disclosure may be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), future radio access (FRA), new radio access technology (RAT), new radio (NR), new radio access (NX), future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (registered trademark), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine-to-Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), systems using other communication methods, and systems based on them Expanded next-generation systems, etc. In addition, multiple systems can also be combined (for example, a combination of LTE or LTE-A and 5G, etc.) for application.

In some embodiments, the terminal may be subject to cross-link interference (CLI) during communication. For example, in a dynamic time division duplex (DTDD) scenario, the TDD structures in two adjacent cells may be different. The TDD structure in cell A is DDDSU, and the TDD structure in the adjacent cell B is DSUUU, where D represents a downlink time slot, S represents a flexible time slot, and U represents an uplink time slot.

It can be seen that the third time slot in cell A is a downlink time slot, but the third time slot in cell B is an uplink time slot. When the terminal communicates in cell A, downlink communication can be performed in the third time slot, but the terminal in cell B will perform uplink communication in the third time slot. This results in that in the third time slot, the terminal in cell A will receive the information sent by the terminal in cell B, which will cause cross-link interference to the terminal in cell A.

In some embodiments, the terminal may measure the cross-link interference, for example, by receiving a reference signal of the cross-link interference, and report the obtained measurement result to the network device, so that the network device may use an appropriate communication method to mitigate the cross-link interference when subsequently communicating with the terminal.

Although the terminal can measure the cross-link interference by receiving the cross-link interference reference signal, in the 5G communication system, the signal can be sent and received on the beam. If the cross-link interference reference signal on a specific beam is not measured, then even if the network equipment receives the measurement results, it is difficult to accurately determine which beam has stronger cross-link interference and which beam has weaker cross-link interference, and it is difficult to adopt appropriate communication methods to alleviate cross-link interference.

For example, step S201 may be implemented as an independent embodiment, step S202 may be implemented as an independent embodiment, and step S201+S202 may be implemented as an independent embodiment, but is not limited thereto.

In some embodiments, steps S201 and S202 may be performed in an interchangeable order or simultaneously.

In some embodiments, reference may be made to other optional implementations recorded before or after the description corresponding to FIG. 2 .

In a first aspect, an embodiment of the present disclosure provides an interference measurement method. Fig. 3 is a schematic flow chart of an interference measurement method according to an embodiment of the present disclosure. The interference measurement method shown in this embodiment may be executed by a terminal.

As shown in FIG3 , the interference measurement method may include the following steps:

In step S301, indication information sent by a network device is received, wherein the indication information is used to indicate a spatial relationship of a cross-link interference reference signal;

In step S302, a cross-link interference reference signal is received according to the spatial relationship.

It should be noted that the embodiment shown in FIG. 3 may be implemented independently or in combination with at least one other embodiment in the present disclosure. The specific implementation may be selected as needed and the present disclosure is not limited thereto.

In some embodiments, the network device may send indication information to the terminal, and the terminal may determine the spatial relationship (spatialRelation) of the cross-link interference reference signal according to the indication information.

For example, the cross-link interference reference signal includes but is not limited to a Sounding Reference Signal (SRS).

For example, when the embodiment of the present disclosure is executed by terminal #1 in cell A, terminal #1 in cell A may receive SRS based on network configuration and obtain a measurement result by measuring SRS. For example, SRS includes at least one of the following: SRS sent by other terminals other than terminal #1 in cell A; SRS sent by terminals in neighboring cells of cell A.

For example, the indicators of the measurement results include at least one of the following: Reference Signal Receiving Power (RSRP) determined by measuring the cross-link interference reference signal; Received Signal Strength Indication (RSSI) determined by measuring the cross-link interference reference signal. Of course, the indicators of the measurement results are not limited to RSRP and RSSI, and may also include other indicators, such as Signal to Interference plus Noise Ratio (SINR).

In some embodiments, the spatial relationship of the cross-link interference reference signal may include a first reference signal having a quasi co-location relationship with the cross-link interference reference signal. The terminal may determine the first reference signal according to the spatial relationship, and determine a beam associated with the first reference signal. For example, the beam associated with the first reference signal includes a beam used by the terminal to receive the first reference signal, and the terminal may receive the cross-link interference reference signal based on the above beam.

According to an embodiment of the present disclosure, the terminal may receive a cross-link interference reference signal according to a determined spatial relationship. For example, the terminal may receive the cross-link interference reference signal on a beam associated with a determined first reference signal.

Since the spatial relationship based on which the terminal receives the cross-link interference reference signal is indicated by the network device, the spatial relationship is also known to the network device. Based on this, it is convenient for the network device to determine the spatial relationship based on which the terminal receives the cross-link interference reference signal after receiving the measurement result reported by the terminal, such as the beam where the terminal receives the cross-link interference reference signal, so that the network device can accurately determine the cross-link interference on the beam, so that when subsequently communicating with the terminal on the beam, the network device can determine the appropriate communication method to alleviate the cross-link interference on the beam. From another perspective, the terminal measures the cross-link interference on the determined beam according to the spatial relationship, which is beneficial for the base station to determine the cross-link interference on different beams, so that data scheduling can be performed on beams with relatively small cross-link interference in the future, which is beneficial to ensuring communication quality.

Furthermore, since the spatial relationship based on which the terminal receives the cross-link interference reference signal is scheduled by the network device configuration rather than being determined autonomously by the terminal, it is helpful to ensure the controllability of the network device's operation for measuring cross-link interference by the terminal.

In some embodiments, the interference measurement method further includes: determining a spatial relationship of a cross-link interference reference signal according to implementation when the indication information is not received.

When the terminal receives the indication information sent by the network device, the terminal can receive the cross-link interference reference signal according to the spatial relationship indicated by the indication information as shown in the above embodiment. When the indication information is provided, when it is necessary to measure the cross-link interference, the terminal can determine the spatial relationship of the cross-link interference reference signal according to the implementation. For example, the terminal can autonomously determine the first reference signal that is quasi-co-located with the cross-link interference reference signal according to the specific circumstances, and receive the cross-link interference reference signal on the beam associated with the first reference signal.

For example, the terminal can determine the beam where the downlink information was received most recently, and receive the cross-link interference reference signal on the beam. The downlink information includes one of the following: Physical Downlink Control Channel (PDCCH) and Physical Downlink Shared Channel (PDSCH).

In some embodiments, the interference measurement method further includes: sending a measurement result of the cross-link interference to the network device.

After receiving the cross-link interference reference signal according to the spatial relationship, the terminal can measure the cross-link interference reference signal to obtain a measurement result, and report the measurement result to the network device. For example, the terminal can determine the resource for sending the measurement result according to the configuration information sent by the network device, and then send the measurement result on the resource. After receiving the measurement result, the network device can determine that the terminal receives the cross-link interference reference signal according to the spatial relationship indicated by the network device, and then obtains the measurement result.

For example, the indication information sent by the network device to the terminal indicates that the spatial relationship includes that the first reference signal and the cross-link interference reference signal have a quasi-co-location relationship, and the beam associated with the first reference signal is the first beam, then the terminal can receive the cross-link interference reference signal in the first beam, and then report the obtained measurement result to the network device. The network device can determine that the measurement result received from the terminal is the measurement result obtained by the terminal measuring the cross-link interference on the first beam.

In some embodiments, the indication information sent by the network device to the terminal each time may indicate a spatial relationship. In this case, when the network device sends indication information to the terminal n times, a different spatial relationship may be indicated each time. The terminal may determine multiple beams for measuring cross-link interference based on multiple indication information, such as beam#1 to beam#n, a total of n beams, and may also measure cross-link interference on these n beams to obtain measurement results and report them to the network device. After receiving a measurement result each time, the network device may determine the beam corresponding to the measurement result. For example, if the spatial relationship indicated by the indication information includes a first reference signal that is quasi-co-located with a cross-link interference reference signal, and the beam associated with the first reference signal is beam#i, the network device may determine that the most recent measurement result received after sending the indication is the measurement result obtained by the terminal measuring cross-link interference on beam#i.

In some embodiments, the indication information sent by the network device to the terminal at one time may indicate multiple spatial relationships. The terminal may determine multiple beams for measuring cross-link interference according to the multiple spatial relationships, such as beam#1 to beam#n, a total of n beams, and may also measure the cross-link interference on the n beams respectively to obtain the measurement results and report them to the network device.

For example, in addition to the measurement results, the measurement results may also include an association relationship between the measurement results and the resources, and accordingly, the network device may determine the beam corresponding to each measurement result according to the association relationship. For example, the association relationship included in the measurement result report#i is associated with the cross-link interference reference signal resource resource#i, and resource#i corresponds to beam beam#i. The network device may determine that report#i is the measurement result obtained by the terminal measuring the cross-link interference on beam#i according to the association relationship in report#i.

For example, the measurement result may not include the association between the measurement result and the beam, but is reported to the network device in a first order. The first order is known to the network device, and the network device can determine the beam corresponding to each measurement result according to the first order. For example, the first order includes a cross-link interference reference signal resource identifier, or an identifier of a transmission configuration indication (TCI) state, and an identifier of a first reference signal determined according to a spatial relationship from small to large (not limited to small to large, but also from large to small).

Take the first order including the cross-link interference reference signal resource identifier from small to large as an example, for example, with 4 resources Taking resource#1 to resource#4 as an example, resource#1 corresponds to beam beam#1, resource#2 corresponds to beam beam#2, resource#3 corresponds to beam beam#3, and resource#4 corresponds to beam beam#4. The network device can determine that the first measurement result is the measurement result obtained by the terminal measuring cross-link interference on resource#1 according to the reception order in multiple reception processes or the sorting of multiple measurement results in one reception process, and the beam in which it is located is beam#1; the second measurement result received is the measurement result obtained by the terminal measuring cross-link interference on resource#2, and the beam in which it is located is beam#2; the third measurement result received is the measurement result obtained by the terminal measuring cross-link interference on resource#3, and the beam in which it is located is beam#3; the fourth measurement result received is the measurement result obtained by the terminal measuring cross-link interference on resource#4, and the beam in which it is located is beam#4.

For example, a measured cross-link interference reference signal resource corresponds to a beam, and the measurement result may not include the association between the measurement result and the resource, for example, the cross-link interference reference signal resource resource#i corresponds to the beam beam#i, or the transmission configuration indication state (TCI state) of resource#i corresponds to the beam beam#i. After the terminal measures the cross-link interference reference signal on beam#i according to the cross-link interference reference signal resource resource#i to obtain the measurement result, it can report the measurement result to the network device on the measurement result reporting resource corresponding to the cross-link interference reference signal resource. The network device can determine that the reporting resource corresponds to resource#i according to the reporting resource where the measurement result is located, and then determine that resource#i or the TCI state of resource#i corresponds to beam#i, thereby determining that the received measurement result is the measurement result obtained by the terminal measuring the cross-link interference on beam#i.

In some embodiments, the interference measurement method further includes: determining a first beam associated with a minimum measurement result; and receiving downlink information of a network device on the first beam. For example, if the indicator of the measurement result includes RSRP, the measurement result corresponding to the minimum RSRP can be determined as the minimum measurement result among multiple measurement results.

After the terminal reports the measurement result to the network device, the network device can determine the beam corresponding to the measurement result, that is, it can determine on which beam the received measurement result is the measurement result obtained by the terminal measuring the cross-link interference. When the terminal measures the cross-link interference on multiple beams respectively and obtains multiple measurement results, the multiple measurement results can be reported to the network device.

For example, the network device may determine the minimum measurement result among multiple measurement results, and send downlink information to the terminal on the first beam associated with the minimum measurement result (that is, the measurement result obtained by measuring the cross-link interference on the first beam is the smallest).

For example, the terminal can determine the minimum measurement result based on multiple measurement results, and receive downlink information sent by the network device on the first beam associated with the minimum measurement result. Since the measurement result on the first beam is the smallest, that is, the cross-link interference is the smallest, the terminal communicates with the network device on the first beam, which is conducive to ensuring good communication quality.

In some embodiments, the interference measurement method further includes: determining a first beam associated with a measurement result less than a first threshold, and receiving downlink information of a network device on the first beam. The measurement result less than the first threshold may be one measurement result or multiple measurement results.

In some embodiments, the indication information includes at least one of the following:

Radio Resource Control (RRC) signaling;

Downlink control information (DCI);

Media Access Control Control Element (MAC CE).

In some embodiments, the spatial relationship in the radio resource control signaling includes: information of a first reference signal; wherein the first reference signal has a quasi-co-location relationship with a cross-link interference reference signal. For example, an information element (IE) in the radio resource control signaling, spatial relationship information (spatialRelationInfo or spatialRelationInfo-r18) can be used as indication information to indicate the spatial relationship.

The terminal can determine the first reference signal according to the spatial relationship, and determine the beam associated with the first reference signal, and then the terminal can receive the cross-link interference reference signal on the beam associated with the determined first reference signal. Since the spatial relationship is also known to the network device, the network device can determine the beam where the terminal receives the cross-link interference reference signal after receiving the measurement result reported by the terminal, so that the network device can accurately determine the cross-link interference on the beam, so that when subsequently communicating with the terminal on the beam, the network device can determine the appropriate communication method to alleviate the cross-link interference on the beam.

In some embodiments, the spatial relationship information may belong to a cross-link interference reference signal resource in an RRC IE, such as a sounding reference signal resource (e.g., SRS resource). In addition to the spatial relationship information, the cross-link interference reference signal resource may also include an identifier of a cross-link interference reference signal resource (e.g., CLI-RS-ResourceId), and the identifier of the cross-link interference reference signal resource may correspond to at least one cross-link interference reference signal resource.

Since the indication information may belong to the cross-link interference reference signal resources in the RRC IE, and the cross-link interference reference signal resources also include the identifier of the cross-link interference reference signal resources, the indication information corresponds to the cross-link interference reference signal resources and the identifier of the cross-link interference reference signal resources. Therefore, in the embodiment of the present disclosure, the indication information indicates the spatial relationship of the cross-link interference reference signal, and may also be described as indicating the spatial relationship of the cross-link interference reference signal resources or the identifier of the cross-link interference reference signal resources.

In some embodiments, the first reference signal includes at least one of the following:

Synchronization Signal PBCH (Physical Broadcast Channel) Block (SSB), also known as synchronization signal block;

Channel State Information Reference Signal (CSI-RS);

Sounding Reference Signal (SRS).

For example, the first reference signal may include SSB and CSI-RS, but not SRS. Since the beam corresponding to the current SRS is an uplink beam, and the SRS in the disclosed embodiment includes the SRS received by the terminal from other terminals, that is, the corresponding beam is a downlink beam. When the first reference signal does not include SRS, when determining the beam corresponding to the first reference signal based on the spatial relationship, there is no need to distinguish whether the beam is an uplink beam or a downlink beam, which is conducive to improving the accuracy of the spatial relationship indication. Then the terminal can receive the cross-link interference reference signal on the beam associated with the SSB, and can also receive the cross-link interference reference signal on the beam associated with the CSI-RS.

Taking the sounding reference signal spatial relationship information (SRS-spatialRelationInfo) as the first indication information as an example, the specific IE structure may be as follows:

SRS-spatialRelationInfo::SEQUENCE{

servingCellId ServingCellIndex OPTIONAL,--Need S

referenceSignal CHOICE{

ssb-Index SSB-Index

csi-RS-index NZP-CSI-RS-ResourceId,

}}

It can be seen that only SSB and CSI-RS are indicated, but SRS is not indicated.

For example, the first reference signal may include SSB, CSI-RS and SRS. Since the current sounding reference signal spatial relationship information includes SSB, CSI-RS and SRS, the first reference signal in this embodiment includes SSB, CSI-RS and SRS, which can reduce the modification of existing IE and help reduce the impact on standards (such as communication protocols). Then the terminal can receive the cross-link interference reference signal on the beam associated with SSB, and can also receive the cross-link interference reference signal on the CSI-RS. The cross-link interference reference signal is received on the associated beam, and the cross-link interference reference signal can also be received on the SRS associated beam.

Taking the sounding reference signal spatial relationship information (SRS-spatialRelationInfo) as the first indication information as an example, the specific IE structure may be as follows:

SRS-spatialRelationInfo::SEQUENCE{

servingCellId ServingCellIndex OPTIONAL,--Need S

referenceSignal CHOICE{

ssb-Index SSB-Index

csi-RS-index NZP-CSI-RS-ResourceId,

srs SEQUECE{

resourceId SRS-ResourceId,

uplinkBWP BWP-Id}

}}

It can be seen that SSB, CSI-RS and SRS are indicated.

In some embodiments, the interference measurement method further includes: updating the spatial relationship according to the update information sent by the network device. The network device may send the update information to update the spatial relationship indicated by the indication information, and the terminal may determine the updated spatial relationship according to the update information, and then receive the cross-link interference reference signal according to the updated spatial relationship. For example, the update information includes but is not limited to at least one of the following: DCI, MAC CE.

Since the indication information used to indicate the spatial relationship is generally RRC signaling, and RRC signaling is generally sent by the network device to the terminal when the terminal enters and leaves the connected state, the spatial relationship is adjusted by re-indicating the spatial relationship through the indication information, and the delay of the adjustment operation is relatively large. In this embodiment, the spatial relationship can be updated through signaling such as DCI and MAC CE. Compared with RRC signaling, DCI and MAC CE can be dynamically sent by the network device to the terminal during the communication process, which is conducive to reducing the delay of adjusting the spatial relationship.

In some embodiments, the type of the cross-link interference reference signal includes at least one of the following: periodic; semi-persistent; aperiodic.

In some embodiments, the interference measurement method also includes: receiving configuration information of a periodic cross-link interference reference signal, the configuration information periodically determining the resources of the periodic cross-link interference reference signal; wherein, receiving the cross-link interference reference signal according to the spatial relationship includes: receiving the cross-link interference reference signal on the resource based on the spatial relationship of the cross-link interference reference signal.

For example, when the cross-link interference reference signal is a periodic cross-link interference reference signal, the network device may configure a periodic resource for the cross-link interference reference signal through configuration information. For example, the configuration information includes but is not limited to RRC signaling.

In this case, after receiving the configuration information, the terminal can determine the resources of the periodic cross-link interference reference signal according to the configuration information, and then can receive the cross-link interference reference signal based on the spatial relationship on the determined resources.

In some embodiments, the interference measurement method further includes: receiving configuration information of a semi-persistent cross-link interference reference signal, the configuration information being used to determine a resource of the semi-persistent cross-link interference reference signal; wherein receiving the cross-link interference reference signal according to the spatial relationship includes: after determining resource activation according to the activation information, receiving the cross-link interference reference signal on the resource based on the spatial relationship of the cross-link interference reference signal. For example, the configuration information includes but is not limited to RRC signaling.

For example, in the case where the cross-link interference reference signal is a semi-persistent cross-link interference reference signal, the network device may configure a semi-persistent resource for the cross-link interference reference signal through configuration information, and subsequently activate the configured resource through activation information. For example, the activation information includes at least one of the following: DCI, MAC CE, wherein when the measurement result of the cross-link interference is reported to the network device based on the Physical Uplink Control Channel (PUCCH), the activation information may be MAC CE, and when the measurement result of the cross-link interference is reported to the network device based on the Physical Uplink Shared Channel (PUSCH), the activation information may be DCI.

In this case, after receiving the configuration information, the terminal can determine the resource of the semi-persistent cross-link interference reference signal according to the configuration information, and then after receiving the activation information, it can determine that the resource is activated, so as to receive the cross-link interference reference signal on the resource based on the spatial relationship.

In some embodiments, the interference measurement method also includes: receiving configuration information of a non-periodic cross-link interference reference signal, the configuration information is used to determine the resources of the non-periodic cross-link interference reference signal; wherein, receiving the cross-link interference reference signal according to the spatial relationship includes: after determining the resource activation according to the activation information, receiving the cross-link interference reference signal on the resource based on the spatial relationship of the cross-link interference reference signal.

For example, when the cross-link interference reference signal is an aperiodic cross-link interference reference signal, the network device may configure an aperiodic resource for the cross-link interference reference signal through configuration information, and subsequently activate the configured resource through activation information. For example, the activation information includes but is not limited to DCI.

In this case, after receiving the configuration information, the terminal can determine the resources of the non-periodic cross-link interference reference signal based on the configuration information, and then after receiving the activation information, it can determine that the resources are activated, thereby receiving the cross-link interference reference signal on the resource based on the spatial relationship of the cross-link interference reference signal.

In some embodiments, the network device may carry signaling in the activation information to update the spatial relationship. As in the previous embodiment, the activation information may be, for example, dynamic signaling such as DCI and MAC CE. Compared with RRC signaling, DCI and MAC CE may be dynamically sent by the network device to the terminal during the communication process, which is beneficial to reduce the delay in adjusting the spatial relationship. In some embodiments, the network device may update a specific spatial relationship. For example, the DCI and MAC CE may carry the identification and update configuration of the cross-link interference reference signal resource. The terminal determines the cross-link interference reference signal resource based on the identification, and updates the spatial relationship corresponding to the cross-link interference reference signal resource based on the update configuration.

In some embodiments, the network device can configure at least one report configuration (reportconfig) for the terminal (for example, through RRC signaling configuration), the report configuration can include configuration information, the activation information (for example, DCI) can indicate the identifier of the activated report configuration, such as reportconfig ID, the terminal can determine that the resources configured by the configuration information in the reportconfig activated by the activation information are the resources of the activated non-periodic cross-link interference reference signal, and receive the cross-link interference reference signal on the resource based on the spatial relationship of the cross-link interference reference signal.

It should be noted that the reporting method of the measurement result of the cross-interference link can be implemented based on the reporting framework of the channel state information (CSI). In addition, the activation information in the above embodiment can also be implemented based on the activation signaling of the channel state information.

The embodiment of the present disclosure proposes an interference measurement method. Figure 4 is a schematic flow chart of an interference measurement method according to an embodiment of the present disclosure. The interference measurement method shown in this embodiment can be executed by an access network device.

As shown in FIG4 , the interference measurement method may include the following steps:

In step S401, indication information is sent to a terminal, wherein the indication information is used to indicate a spatial relationship of a cross-link interference reference signal.

In some embodiments, the network device may send indication information to the terminal, and the terminal may determine Determine the spatial relationship (spatialRelation) of the cross-link interference reference signal.

For example, the cross-link interference reference signal includes, but is not limited to, a listening reference signal (SRS).

For example, when the embodiment of the present disclosure is executed by terminal #1 in cell A, terminal #1 in cell A may receive SRS based on network configuration and obtain a measurement result by measuring SRS. For example, SRS includes at least one of the following: SRS sent by other terminals other than terminal #1 in cell A; SRS sent by terminals in neighboring cells of cell A.

For example, the indicator of the measurement result includes at least one of the following: a reference signal received power (RSRP) determined by measuring a cross-link interference reference signal; a received signal strength indication (RSSI) determined by measuring a cross-link interference reference signal. Of course, the indicator of the measurement result is not limited to RSRP and RSSI, and may also include other indicators, such as a signal to interference plus noise ratio (SINR).

In some embodiments, the spatial relationship of the cross-link interference reference signal may include a first reference signal having a quasi co-location relationship with the cross-link interference reference signal. The terminal may determine the first reference signal according to the spatial relationship, and determine a beam associated with the first reference signal. For example, the beam associated with the first reference signal includes a beam used by the terminal to receive the first reference signal. The terminal may receive the cross-link interference reference signal based on the above.

According to an embodiment of the present disclosure, the network device may indicate a spatial relationship to the terminal, and the terminal may receive a cross-link interference reference signal based on the determined spatial relationship. For example, the terminal may receive the cross-link interference reference signal on a beam associated with a determined first reference signal.

Since the spatial relationship based on which the terminal receives the cross-link interference reference signal is indicated by the network device, the spatial relationship is also known to the network device. Based on this, it is convenient for the network device to determine the spatial relationship based on which the terminal receives the cross-link interference reference signal after receiving the measurement result reported by the terminal, such as the beam where the terminal receives the cross-link interference reference signal, so that the network device can accurately determine the cross-link interference on the beam, so that when subsequently communicating with the terminal on the beam, the network device can determine the appropriate communication method to alleviate the cross-link interference on the beam. From another perspective, the terminal measures the cross-link interference on the determined beam according to the spatial relationship, which is beneficial for the base station to determine the cross-link interference on different beams, so that data scheduling can be performed on beams with relatively small cross-link interference in the future, which is beneficial to ensuring communication quality.

Furthermore, since the spatial relationship based on which the terminal receives the cross-link interference reference signal is scheduled by the network device configuration rather than being determined autonomously by the terminal, it is helpful to ensure the controllability of the network device's operation for measuring cross-link interference by the terminal.

In some embodiments, the interference measurement method further includes: receiving a measurement result of a cross-link interference reported by a terminal.

After receiving the cross-link interference reference signal according to the spatial relationship, the terminal can measure the cross-link interference reference signal to obtain a measurement result, and report the measurement result to the network device, and the network device can receive the measurement result. For example, the terminal can determine the resource for sending the measurement result based on the configuration information sent by the network device, and then send the measurement result on the resource. After the network device receives the measurement result, it can be determined that the terminal receives the cross-link interference reference signal according to the spatial relationship indicated by the network device, and then obtains the measurement result.

For example, the indication information sent by the network device to the terminal indicates that the spatial relationship includes that the first reference signal and the cross-link interference reference signal have a quasi-co-location relationship, and the beam associated with the first reference signal is the first beam, then the terminal can receive the cross-link interference reference signal in the first beam, and then report the obtained measurement result to the network device. The network device can determine that the measurement result received from the terminal is the measurement result obtained by the terminal measuring the cross-link interference on the first beam.

In some embodiments, the indication information sent by the network device to the terminal each time may indicate a spatial relationship. Then, in the case where the network device sends indication information to the terminal n times, a different spatial relationship can be indicated each time. The terminal can determine multiple beams for measuring cross-link interference based on multiple indication information, such as beam#1 to beam#n, a total of n beams, and can also measure the cross-link interference on these n beams to obtain the measurement results and report them to the network device. After receiving the measurement result each time, the network device can determine the beam corresponding to the measurement result. For example, the spatial relationship indicated by the indication information includes a first reference signal that is quasi-co-located with the cross-link interference reference signal, and the beam associated with the first reference signal is beam#i. Then the network device can determine that the most recent measurement result received after sending the indication is the measurement result obtained by the terminal measuring the cross-link interference on beam#i.

In some embodiments, the indication information sent by the network device to the terminal at one time may indicate multiple spatial relationships. The terminal may determine multiple beams for measuring cross-link interference according to the multiple spatial relationships, such as beam#1 to beam#n, a total of n beams, and may also measure the cross-link interference on the n beams respectively to obtain the measurement results and report them to the network device.

For example, in addition to the measurement results, the measurement results may also include an association relationship between the measurement results and the resources, and accordingly, the network device may determine the beam corresponding to each measurement result according to the association relationship. For example, the association relationship included in the measurement result report#i is associated with the cross-link interference reference signal resource resource#i, and resource#i corresponds to beam beam#i. The network device may determine that report#i is the measurement result obtained by the terminal measuring the cross-link interference on beam#i according to the association relationship in report#i.

For example, the measurement result may not include the association relationship between the measurement result and the resource, but is reported to the network device in a first order. The first order is known to the network device, and the network device can determine the beam corresponding to each measurement result according to the first order. For example, the first order includes a cross-link interference reference signal resource identifier, or a transmission configuration indication (TCI) status identifier, and an identifier of a first reference signal determined according to a spatial relationship from small to large (not limited to small to large, but also from large to small).

Taking the first order including the cross-link interference reference signal resource identifier from small to large as an example, for example, taking 4 resources resource#1 to resource#4 as an example, resource#1 corresponds to beam beam#1, resource#2 corresponds to beam beam#2, resource#3 corresponds to beam beam#3, and resource#4 corresponds to beam beam#4. The network device can determine that according to the receiving order in multiple receiving processes or the sorting of multiple measurement results in one receiving process, the first measurement result is the measurement result obtained by the terminal measuring the cross-link interference on resource#1, and the beam is beam#1; the second measurement result received is the measurement result obtained by the terminal measuring the cross-link interference on resource#2, and the beam is beam#2; the third measurement result received is the measurement result obtained by the terminal measuring the cross-link interference on resource#3, and the beam is beam#3; the fourth measurement result received is the measurement result obtained by the terminal measuring the cross-link interference on resource#4, and the beam is beam#4.

For example, a measured cross-link interference reference signal resource corresponds to a beam, and the measurement result may not include the association between the measurement result and the resource, for example, the cross-link interference reference signal resource resource#i corresponds to the beam beam#i, or the transmission configuration indication state (TCI state) of resource#i corresponds to the beam beam#i. After the terminal measures the cross-link interference reference signal on beam#i according to the cross-link interference reference signal resource resource#i to obtain the measurement result, it can report the measurement result to the network device on the measurement result reporting resource corresponding to the cross-link interference reference signal resource. The network device can determine that the reporting resource corresponds to resource#i according to the reporting resource where the measurement result is located, and then determine that resource#i or the TCI state of resource#i corresponds to beam#i, thereby determining that the received measurement result is the measurement result obtained by the terminal measuring the cross-link interference on beam#i.

In some embodiments, the interference measurement method further includes: determining a first beam associated with a minimum measurement result; and sending downlink information to the terminal on the first beam.

After receiving the measurement result sent by the terminal, the network device can determine the beam corresponding to the measurement result, that is, it can determine on which beam the received measurement result is the measurement result obtained by the terminal by measuring the cross-link interference. If the terminal measures the cross-link interference on multiple beams respectively and obtains multiple measurement results, the multiple measurement results can be The measurement results are reported to the network device.

For example, the network device may determine the minimum measurement result among multiple measurement results, and send downlink information to the terminal on the first beam associated with the minimum measurement result (that is, the measurement result obtained by measuring the cross-link interference on the first beam is the smallest).

For example, the terminal can determine the minimum measurement result based on multiple measurement results, and receive downlink information sent by the network device on the first beam associated with the minimum measurement result. Since the measurement result on the first beam is the smallest, that is, the cross-link interference is the smallest, the terminal communicates with the network device on the first beam, which is conducive to ensuring good communication quality.

In some embodiments, the interference measurement method further includes: determining a first beam associated with a measurement result less than a first threshold, and receiving downlink information of a network device on the first beam. The measurement result less than the first threshold may be one measurement result or multiple measurement results.

In some embodiments, the indication information includes at least one of the following:

Radio Resource Control (RRC) signaling;

Downlink control information (DCI);

Media Access Control Layer Control Element (MAC CE).

In some embodiments, the spatial relationship in the radio resource control signaling includes: information of a first reference signal; wherein the first reference signal has a quasi-co-location relationship with a cross-link interference reference signal. For example, an information element (IE) in the radio resource control signaling, spatial relationship information (spatialRelationInfo or spatialRelationInfo-r18) can be used as indication information to indicate the spatial relationship.

The terminal can determine the first reference signal according to the spatial relationship, and determine the beam associated with the first reference signal, and then the terminal can receive the cross-link interference reference signal on the beam associated with the determined first reference signal. Since the spatial relationship is also known to the network device, the network device can determine the beam where the terminal receives the cross-link interference reference signal after receiving the measurement result reported by the terminal, so that the network device can accurately determine the cross-link interference on the beam, so that when subsequently communicating with the terminal on the beam, the network device can determine the appropriate communication method to alleviate the cross-link interference on the beam.

In some embodiments, the spatial relationship information may belong to a cross-link interference reference signal resource in an RRC IE, such as a sounding reference signal resource (e.g., SRS resource). In addition to the spatial relationship information, the cross-link interference reference signal resource may also include an identifier of a cross-link interference reference signal resource (e.g., CLI-RS-ResourceId), and the identifier of the cross-link interference reference signal resource may correspond to at least one cross-link interference reference signal resource.

Since the indication information may belong to the cross-link interference reference signal resources in the RRC IE, and the cross-link interference reference signal resources also include the identifier of the cross-link interference reference signal resources, the indication information corresponds to the cross-link interference reference signal resources and the identifier of the cross-link interference reference signal resources. Therefore, in the embodiment of the present disclosure, the indication information indicates the spatial relationship of the cross-link interference reference signal, and may also be described as indicating the spatial relationship of the cross-link interference reference signal resources or the identifier of the cross-link interference reference signal resources.

In some embodiments, the first reference signal includes at least one of the following:

Synchronous broadcast signal block (SSB), also known as synchronization signal block;

Channel State Information Reference Signal (CSI-RS);

Sounding Reference Signal (SRS).

For example, the first reference signal may include SSB and CSI-RS, but not SRS. Since the beam corresponding to the current SRS is an uplink beam, and the SRS in the disclosed embodiment includes the SRS received by the terminal from other terminals, that is, the corresponding beam is a downlink beam. When the first reference signal does not include SRS, when determining the beam corresponding to the first reference signal based on the spatial relationship, there is no need to distinguish whether the beam is an uplink beam or a downlink beam, which is conducive to improving the accuracy of the spatial relationship indication. Then the terminal can receive the cross-link interference reference signal on the beam associated with the SSB, and can also receive the cross-link interference reference signal on the beam associated with the CSI-RS.

Taking the sounding reference signal spatial relationship information (SRS-spatialRelationInfo) as the first indication information as an example, the specific IE structure may be as follows:

SRS-spatialRelationInfo::SEQUENCE{

servingCellId ServingCellIndex OPTIONAL,--Need S

referenceSignal CHOICE{

ssb-Index SSB-Index

csi-RS-index NZP-CSI-RS-ResourceId,

}}

It can be seen that only SSB and CSI-RS are indicated, but SRS is not indicated.

For example, the first reference signal may include SSB, CSI-RS and SRS. Since the current sounding reference signal spatial relationship information includes SSB, CSI-RS and SRS, the first reference signal in this embodiment includes SSB, CSI-RS and SRS, which can reduce the modification of existing IEs and help reduce the impact on standards (such as communication protocols). Then the terminal can receive the cross-link interference reference signal on the beam associated with the SSB, the cross-link interference reference signal on the beam associated with the CSI-RS, and the cross-link interference reference signal on the beam associated with the SRS.

Taking the sounding reference signal spatial relationship information (SRS-spatialRelationInfo) as the first indication information as an example, the specific IE structure may be as follows:

SRS-spatialRelationInfo::SEQUENCE{

servingCellId ServingCellIndex OPTIONAL,--Need S

referenceSignal CHOICE{

ssb-Index SSB-Index

csi-RS-index NZP-CSI-RS-ResourceId,

srs SEQUECE{

resourceId SRS-ResourceId,

uplinkBWP BWP-Id}

}}

It can be seen that SSB, CSI-RS and SRS are indicated.

In some embodiments, the interference measurement method further includes: sending update information to the terminal, wherein the update information is used to update the spatial relationship.

The network device may send update information to update the spatial relationship indicated by the indication information, and the terminal may determine the updated spatial relationship according to the update information, and then receive the cross-link interference reference signal according to the updated spatial relationship. For example, the update information includes but is not limited to at least one of the following: DCI, MAC CE.

Since the indication information used to indicate the spatial relationship is generally RRC signaling, and RRC signaling is generally sent by the network device to the terminal when the terminal enters and leaves the connected state, the spatial relationship is adjusted by re-indicating the spatial relationship through the indication information, and the delay of the adjustment operation is relatively large. In this embodiment, the spatial relationship can be updated through signaling such as DCI and MAC CE. Compared with RRC signaling, DCI and MAC CE can be dynamically sent by the network device to the terminal during the communication process, which is conducive to reducing the delay of adjusting the spatial relationship.

In some embodiments, the type of the cross-link interference reference signal includes at least one of the following: periodic; semi-persistent; aperiodic.

In some embodiments, the interference measurement method also includes: sending configuration information of a periodic cross-link interference reference signal to a terminal, wherein the configuration information is used to determine resources of the periodic cross-link interference reference signal, and the resources are used for the terminal to receive the cross-link interference reference signal based on the spatial relationship of the cross-link interference reference signal.

For example, when the cross-link interference reference signal is a periodic cross-link interference reference signal, the network device may configure a periodic resource for the cross-link interference reference signal through configuration information. For example, the configuration information includes but is not limited to RRC signaling.

In this case, after receiving the configuration information, the terminal can determine the resources of the periodic cross-link interference reference signal according to the configuration information, and then can receive the cross-link interference reference signal based on the spatial relationship on the determined resources.

In some embodiments, the interference measurement method also includes: sending configuration information of a semi-persistent cross-link interference reference signal to the terminal, wherein the configuration information is used to determine resources of the semi-persistent cross-link interference reference signal; sending activation information to the terminal, wherein the activation information is used to activate resources, and the activated resources are used for the terminal to receive the cross-link interference reference signal based on the spatial relationship of the cross-link interference reference signal.

For example, in the case where the cross-link interference reference signal is a semi-persistent cross-link interference reference signal, the network device may configure a semi-persistent resource for the cross-link interference reference signal through configuration information, and subsequently activate the configured resource through activation information. For example, the activation information includes at least one of the following: DCI, MAC CE, wherein when the measurement result of the cross-link interference is reported to the network device based on the physical uplink control channel (PUCCH), the activation information may be MAC CE, and when the measurement result of the cross-link interference is reported to the network device based on the physical uplink shared channel (PUSCH), the activation information may be DCI.

In this case, after receiving the configuration information, the terminal can determine the resource of the semi-persistent cross-link interference reference signal according to the configuration information, and then after receiving the activation information, it can determine that the resource is activated, so as to receive the cross-link interference reference signal on the resource based on the spatial relationship.

In some embodiments, the interference measurement method also includes: sending configuration information of a non-periodic cross-link interference reference signal to the terminal, wherein the configuration information is used to determine the resources of the non-periodic cross-link interference reference signal; sending activation information to the terminal, wherein the activation information is used to activate the resources, wherein the activated resources are used for the terminal to receive the cross-link interference reference signal based on the spatial relationship of the cross-link interference reference signal.

For example, when the cross-link interference reference signal is an aperiodic cross-link interference reference signal, the network device may configure an aperiodic resource for the cross-link interference reference signal through configuration information, and subsequently activate the configured resource through activation information. For example, the activation information includes but is not limited to DCI.

In this case, after receiving the configuration information, the terminal can determine the resources of the non-periodic cross-link interference reference signal based on the configuration information, and then after receiving the activation information, it can determine that the resources are activated, thereby receiving the cross-link interference reference signal on the resource based on the spatial relationship of the cross-link interference reference signal.

In some embodiments, the network device may carry signaling in the activation information to update the spatial relationship. As in the above embodiments, the activation information may be, for example, dynamic signaling such as DCI and MAC CE. Compared with RRC signaling, DCI and MAC CE are dynamic signaling. MAC CE can be dynamically sent by the network device to the terminal during the communication process, which is conducive to reducing the delay of adjusting the spatial relationship. In some embodiments, the network device can be updated for a specific spatial relationship. For example, the DCI and MAC CE can carry the identification and update configuration of the cross-link interference reference signal resource. The terminal determines the cross-link interference reference signal resource according to the identification, and updates the spatial relationship corresponding to the cross-link interference reference signal resource according to the update configuration.

In some embodiments, the network device can configure at least one report configuration (reportconfig) for the terminal (for example, through RRC signaling configuration), the report configuration can include configuration information, the activation information (for example, DCI) can indicate the identifier of the activated report configuration, such as reportconfig ID, the terminal can determine that the resources configured by the configuration information in the reportconfig activated by the activation information are the resources of the activated non-periodic cross-link interference reference signal, and receive the cross-link interference reference signal on the resource based on the spatial relationship of the cross-link interference reference signal.

It should be noted that the reporting method of the measurement result of the cross-interference link can be implemented based on the reporting framework of the channel state information (CSI). In addition, the activation information in the above embodiment can also be implemented based on the activation signaling of the channel state information.
