In order to facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions related to the embodiments of the present application are described below.

With the pursuit of speed, latency, high-speed mobility, energy efficiency and the diversity and complexity of the services in future life, the third generation partnership project (3)^rdGeneration Partnership Project, 3GPP) the international organization for standardization began developing 5G. The main application scenarios of 5G are: enhanced Mobile Ultra wide band (eMBB), Low-Latency high-reliability communication (URLLC), and massive Machine-Type communication (mMTC).

On the one hand, the eMBB still targets users to obtain multimedia content, services and data, and its demand is growing very rapidly. On the other hand, because the eMBB may be deployed in different scenarios, such as indoor, urban, rural, etc., and the difference between the capabilities and the requirements is relatively large, it cannot be said that it must be analyzed in detail in conjunction with a specific deployment scenario. Typical applications of URLLC include: industrial automation, electric power automation, remote medical operation (surgery), traffic safety, and the like. Typical characteristics of mtc include: high connection density, small data volume, insensitive time delay service, low cost and long service life of the module, etc.

When NR is deployed early, complete NR coverage is difficult to obtain, so typical network coverage is wide area LTE coverage and islanding coverage mode of NR. Moreover, a large amount of LTE is deployed below 6GHz, and the spectrum below 6GHz available for 5G is rare. NR must therefore be studied for spectrum applications above 6GHz, with limited high band coverage and fast signal fading. Meanwhile, in order to protect the early-stage LTE investment of a mobile operator, a work mode of tight coupling (light interworking) between LTE and NR, namely an MR-DC mode, is provided. Furthermore, NRs may also be deployed independently.

In the TDD mode, a configuration ratio of an Uplink (UL) time domain resource to a Downlink (DL) time domain resource may be statically configured or dynamically configured. At the edge of two cells (e.g., cell 1 and cell 2), there are two terminal devices (e.g., terminal device 1 and terminal device 2), where terminal device 1 is located in cell 1 and terminal device 2 is located in cell 2. The uplink transmission of terminal device 1 may correspond to the downlink reception of terminal device 2, resulting in the uplink transmission of terminal device 1 interfering with the downlink reception of terminal device 2, causing cross-link interference (CLI).

The R15NR specification supports a mechanism that allows dynamic DL/UL allocation. However, no cross-link interference mitigation techniques and coexistence requirements are specified, and thus the use of dynamic DL/UL allocation mechanisms is greatly limited. Duplex flexibility with cross-link interference rejection capability has better user throughput than static UL/DL operation or dynamic UL/DL operation without interference rejection capability.

R16 agrees to introduce UE-to-UE measurement (also referred to as CLI measurement) for CLI, which is mainly that one terminal device measures SRS of another terminal device to find interference, but how and which CLI measurement configurations need to be interacted between network nodes, and also timing problem of CLI measurement configuration and CLI measurement configuration negotiation under MR-DC scenario need to be clear. In addition, on the one hand, the state of the serving cell of the victim terminal device and the active BWP in which the victim terminal device is located may affect the validity of the CLI measurement; on the other hand, violating the serving cell state of the terminal device, and violating the active BWP in which the terminal device is located, may also affect the validity of the CLI measurement. In order to enable the victim terminal device to effectively perform CLI measurement, the following technical solutions of the embodiments of the present application are proposed.

Fig. 2 is a first schematic flowchart of a method for CLI measurement provided in an embodiment of the present application, and as shown in fig. 2, the method for CLI measurement includes the following steps:

step 201: the method comprises the steps that terminal equipment receives CLI measurement configuration sent by network equipment, wherein the CLI measurement configuration is used for determining measurement resources; wherein the CLI measurement configuration is associated with at least one serving cell.

In this embodiment, the network device may be a base station, such as a gbb.

In this embodiment, the terminal device is a victim terminal device, where a CLI measurement configuration configured by the network device for the victim terminal device is used by the victim terminal device to perform CLI measurement, so as to find whether there is interference affecting the terminal device.

Here, the CLI measurement configuration includes information of a measurement resource related to an aggressor terminal device, and in an optional embodiment, the measurement resource is an SRS resource or a Received Signal Strength Indication (RSSI) resource.

It should be noted that the network device may configure one or more CLI measurement configurations for the terminal device, and the technical solution described in the embodiment of the present application may be adopted for each CLI measurement configuration.

In an optional embodiment, the CLI measurement configuration configured by the network device to the terminal device is associated with a CLI measurement object (e.g. a frequency layer of a serving cell). Based on this, the CLI measurement configuration is associated with at least one serving cell, and the at least one serving cell is a serving cell corresponding to the CLI measurement object. In other words, the CLI measurement configuration is associated with a CLI measurement object corresponding to the at least one serving cell. Further, the CLI measurement configuration includes identification information of the at least one serving cell. Here, the identification information of the serving cell may be a serving cell identification (serving cell id) or any information capable of identifying the serving cell.

Step 202: and the terminal equipment determines whether to execute CLI measurement configured for the CLI measurement according to the state of the at least one service cell or the spectrum range where the measurement resource is located.

In the embodiment of the present application, the terminal device autonomously determines whether to perform the CLI measurement (i.e., determines whether to stop the CLI measurement or start the CLI measurement). In an embodiment, the terminal device determines whether to perform CLI measurement configured for the CLI measurement according to a state of the at least one serving cell. In another embodiment, the terminal device determines whether to perform CLI measurement configured for the CLI measurement according to a spectrum range in which the measurement resource is located. This will be described in detail below.

In an embodiment, the terminal device determines whether to perform CLI measurement configured for the CLI measurement according to a state of the at least one serving cell.

1) If the at least one serving cell is in the deactivated state, the terminal equipment stops CLI measurement configured for the CLI measurement; or, if some or all of the at least one serving cell are in an active state, the terminal device starts CLI measurement configured for the CLI measurement.

Here, the at least one serving cell refers to a serving cell to which the CLI measurement configuration is associated. The state for each of the at least one serving cell may be an activated state or a deactivated state. The states of the at least one serving cell may be the same or different, and are independent of each other.

In an alternative embodiment, the terminal device may determine the state of the serving cell according to the following: the terminal device receives a Media Access Control Element (MAC CE) sent by the network device, where the MAC CE is used to determine whether the state of some or all cells in the at least one serving cell is an active state or a deactivated state.

Here, the MAC CE may also be referred to as an SCell activation/deactivation MAC CE. The MAC CE includes a bitmap, each bit in the bitmap corresponds to a state of a serving cell, and a value of the bit is used to indicate whether the state of the serving cell corresponding to the bit is an activated state or a deactivated state. For example: the bit value of 1 (or 0) indicates that the state of the serving cell corresponding to the bit is an activated state (or a deactivated state), and the bit value of 0 (or 1) indicates that the state of the serving cell corresponding to the bit is a deactivated state (or an activated state). The terminal device may determine that the state of some or all of the at least one serving cell is an activated state or a deactivated state according to the MAC CE.

In another alternative embodiment, the terminal device may determine the state of the serving cell according to the following: the terminal device determines whether a state of some or all of the at least one serving cell is an activated state or a deactivated state based on whether a deactivation timer has expired.

Here, the deactivation timer may also be referred to as an SCell deactivation timer. And in the running process of the deactivation timer, the service cell associated with the deactivation timer is in a deactivation state, and if the deactivation timer runs out of time, the service cell associated with the deactivation timer is switched to an activation state. It should be noted that, the deactivation timer may be associated with one serving cell or multiple serving cells, and the terminal device may determine that the state of some or all of the at least one serving cell is an activated state or a deactivated state according to whether the deactivation timer is expired.

2) If the at least one serving cell is in the first state or the current BWP of the at least one serving cell is dormant BWP, the terminal equipment stops CLI measurement configured for the CLI measurement; or, if some or all of the at least one serving cell are in the second state, the terminal device starts CLI measurement configured for the CLI measurement.

In an alternative embodiment, the terminal device may determine the state of the serving cell according to the following: the terminal device receives Downlink Control Information (DCI) sent by the network device, where the DCI is used to determine whether a state of some or all of the at least one serving cell is a first state or a second state, where the first state is an active state with a dormant (dormant) behavior, and the second state is an active state with a non-dormant (non-dormant) behavior.

For the activated state, the activated state has a dormancy behavior and a non-dormancy behavior, i.e., the dormancy behavior is part of the activated state. Based on this, the activated state having the dormancy behavior is referred to as a first state, and the activated state having the non-dormancy behavior is referred to as a second state.

Here, the DCI is used to control a transition of the SCell from a first state to a second state. For the first state (i.e., the active state with the dormant behavior), the terminal device may stay on the dormant BWP (dormant BWP) to implement the dormant behavior, and specifically, configure a dormant BWP (dormant BWP) for the SCell, and switch the BWP of the SCell to the dormant BWP through a DCI manner, thereby implementing the dormant behavior of the SCell (i.e., the SCell is in the first state).

It should be noted that the serving cell in the embodiment of the present application may be an SCell.

In another embodiment, the terminal device determines whether to perform CLI measurement configured for the CLI measurement according to a spectrum range in which the measurement resource is located.

Here, the measurement resource is an SRS resource or an RSSI resource.

Specifically, if the spectrum range where the measurement resource is located is not on the active BWP, the terminal device stops CLI measurement configured for the CLI measurement; or, if the spectrum range where the measurement resource is located is on an active BWP, the terminal device starts CLI measurement configured for the CLI measurement.

In the foregoing solution, the active BWP is the BWP in which the serving cell where the terminal device is located, where the serving cell where the terminal device is located is in a second state, and the second state is an active state with a non-dormant behavior.

For example: and stopping CLI measurement if the frequency spectrum range of the SRS resource or RSSI resource configured by the CLI measurement is not on the BWP (namely, the active BWP) of the serving cell in the second state, otherwise starting the CLI measurement.

In an optional implementation manner, if the terminal device stops the CLI measurement configured for the CLI measurement, the terminal device sends a first notification message to the network device, where the first notification message is used to notify an identifier of the stopped CLI measurement.

Here, each CLI measurement may correspond to an identifier, and for a CLI measurement for which measurement is stopped, the terminal device may notify the network side of the identifier of the CLI measurement.

Further, the first notification message is carried by Radio Resource Control (RRC) signaling or MAC CE.

Fig. 3 is a schematic flowchart of a second method for controlling CLI measurement according to an embodiment of the present disclosure, where as shown in fig. 3, the method for controlling CLI measurement includes the following steps:

step 301: and the terminal equipment receives a measurement control command sent by the network equipment, wherein the measurement control command is used for indicating to stop CLI measurement or start CLI measurement.

In this embodiment, the network device may be a base station, such as a gbb.

In the embodiment of the present application, the terminal device determines whether to perform CLI measurement (i.e., determines whether to stop CLI measurement or start CLI measurement) based on control on the network side. Specifically, the terminal device receives a measurement control command sent by the network device, where the measurement control command is used to instruct to stop CLI measurement or start CLI measurement.

In an optional embodiment, the measurement control command carries identification information of at least one CLI measurement; the identification information of the at least one CLI measurement is used to determine the CLI measurement that needs to be stopped or the CLI measurement that needs to be started. Here, which CLI measurements are stopped or started is indicated by carrying identification information of the CLI measurements (which may also be simply referred to as measurement id) in the measurement control command.

In another optional embodiment, the measurement control command carries identification information of at least one serving cell; the identification information of the at least one serving cell is used for determining the CLI measurement needing to be stopped or the CLI measurement needing to be started. Here, which CLI measurements to stop or start is indicated by carrying identification information of at least one serving cell (i.e. identification information of a serving cell associated with the CLI measurement configuration) in the measurement control command.

In yet another optional implementation, the measurement control command carries a first bitmap, each bit in the first bitmap corresponds to a state of CLI measurement or a state of CLI measurement corresponding to a serving cell, and a value of the bit is used to indicate that the CLI measurement corresponding to the bit is in a start state or a stop state. For example: a bit value of 1 (or 0) indicates that the state of the CLI measurement corresponding to the bit is a stopped state (or a started state), and a bit value of 0 (or 1) indicates that the state of the CLI measurement corresponding to the bit is a started state (or a stopped state).

In a further optional embodiment, the measurement control command carries an identifier of at least one measurement resource, based on which the measurement control command is used to instruct to stop CLI measurement for the at least one measurement resource or to start CLI measurement for the at least one measurement resource. Further, optionally, the measurement resource is an SRS resource or an RSSI resource. The measurement control command carries at least one SRS resource identifier (SRS resource id) and/or RSSI resource identifier (RSSI resource id).

Fig. 4 is a third schematic flowchart of a method for controlling CLI measurement according to an embodiment of the present application, where as shown in fig. 4, the method for controlling CLI measurement includes the following steps:

step 401: the first network equipment receives first information sent by second network equipment, wherein the first information is activation information associated with the second terminal equipment.

In this embodiment, the network device may be a base station, such as a gbb. Further, the first network device is a base station where the victim terminal device is located, and the second network device is a base station where the aggressor terminal device is located.

In this embodiment, the second terminal device is an infringing terminal device, and the following related first terminal device is a victim terminal device. Wherein the victim terminal device performs CLI measurements to find out whether there is interference aggressing the terminal device.

In an optional embodiment, the first network device receives the first information sent by the second network device in case of at least one of the following events:

the serving cell of the second terminal device is deactivated;

the service small of the second terminal equipment is switched to the dormant BWP;

the second terminal device performs BWP handover.

In an optional embodiment, the first information comprises at least one of:

the first indication information is used for indicating the cell information of the second terminal equipment in an activated state;

second indication information, wherein the second indication information is used for indicating cell information of a second terminal device in a second state, and the second state is an activated state with a non-dormant behavior;

third indication information indicating identification information of the second terminal device for activating BWP.

For example: if the serving cell of the aggressor terminal device is deactivated or is in the dormant BWP or performs the BWP handover, the aggressor base station sends the currently activated cell information of the aggressor terminal device and/or the cell information in the second state (i.e. the activated state with non-dormant behavior) and/or the currently activated BWP id and the configuration information to the victim base station.

Step 402: and the first network equipment determines whether to send a measurement control command to the first terminal equipment or not according to the first information and second information, wherein the second information is activation information or deactivation information associated with the first terminal equipment.

In an optional embodiment, the second information comprises at least one of:

fourth indication information, where the fourth indication information is used to indicate that a serving cell of the first terminal device is in an activated state or a deactivated state;

the fifth indication information is used for indicating that a serving cell of the first terminal device is in a first state or a second state, the first state is an activated state with a dormant behavior, and the second state is an activated state with a non-dormant behavior;

sixth indication information indicating identification information of the first terminal device for activating BWP.

For example: the victim base station determines whether to issue the CLI measurement control command to the victim terminal device according to the first information sent by the aggressor base station and the state (such as an activated/deactivated state, a dormant/non-dormant state) of the serving cell of the victim terminal device and/or the currently activated BWP.

It should be noted that, the first network device determines whether to send the measurement control command to the first terminal device according to the first information and the second information, which may be implemented with reference to the judgment criterion of the terminal device in the method shown in fig. 2.
