Description

Information processing method and apparatus, network node, and terminal

[0001] The present disclosure claims priority to a Chinese patent application No. 202411385650.2, filed on September 30, 2024, and entitled "Information processing method and apparatus, network node, and terminal", the entire content of which is incorporated herein by reference. TECHNICAL FIELD

[0002] The present disclosure relates to the field of communication technology, and in particular to an information processing method and apparatus, a network node, and a terminal. BACKGROUND

[0003] In order to realize fast cell switching, some candidate cells and reference signal (RS) information of the candidate cells are pre-configured for a terminal or user equipment (UE). This mechanism is based on periodic RS (such as periodic synchronization signal block (SSB)) measurement and access through resources reserved by the candidate node. After pre-configuration, the UE can perform measurement on the RS and report a layer 1 (L1) measurement report to a source node or serving node. After evaluation by the source node or serving node, the UE is triggered to perform cell switching, which can realize faster cell switching.

[0004] In addition, from the perspective of network energy saving and measurement enhancement, SSB transmitted on demand, periodic channel state information reference signal (CSI-RS), aperiodic CSI-RS, semi-static CSI-RS, and the like can also be used as measurement RS. When the UE performs measurement on the specified RS, it is necessary to ensure that the candidate cell is transmitting the RS. However, the current technology does not support inter-node interaction RS activation, and only supports the source node or the serving node to notify the UE of the activation and / or deactivation of the RS of the current cell, and cannot support the source node or the serving node to notify the UE of the RS activation of other cells under the current node or cells under other nodes. Therefore, the source node or the serving node cannot obtain the RS activation state of the candidate cell / node, and cannot timely trigger the UE to perform measurement on the candidate cell or stop measurement; the fast handover of the UE also needs the candidate cell to reserve resources for access to ensure the cell handover of the UE. Based on the mechanism in the related art, the resources of the candidate cell need to be reserved for a long time after pre-configuration, which can cause resource waste. It can be seen that the current method for realizing fast cell handover can only support periodic SSB as measurement RS, and also causes resource occupation and waste because the candidate cell needs to reserve resources for access. That is, when considering extending more types of measurement RS, there is currently no solution to how to ensure fast cell handover and reduce resource occupation and waste. SUMMARY

[0005] The present disclosure provides an information processing method, device, network node and terminal, which solves the problem that there is currently no solution to how to ensure fast cell handover and reduce resource occupation and waste when considering extending more types of measurement RS.

[0281] In the embodiments of the present disclosure, the term "a plurality of" means two or more, and other quantifiers are similar.

[0282] The technical solutions in the embodiments of the present disclosure will be described clearly and completely in combination with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present disclosure.

[0283] The related technologies involved in the present disclosure are introduced as follows:

[0284] 1. Layer 1 / Layer 2 mobility (LTM)

[0285] LTM means that the network side pre-configures the LTM candidate cell configuration information and L1 measurement configuration information (i.e. RS information of the candidate cell) for the UE. The UE performs L1 measurement based on the L1 measurement configuration information and reports the L1 measurement result to the network side. The network side makes a cell change (handover) decision based on the L1 measurement result information reported by the UE. The movement of the UE is limited to the same CU, such as intra-DU or inter-DU movement between different DUs under the same CU, or inter-CU movement. If the network side decides to change the cell (handover), the serving / source DU side will make a cell change (handover) decision based on the received L1 measurement result and send a cell change (handover) command to the UE through a medium access control control element (MAC CE).

[0286] In the current LTM, only SSB is supported as a measurement RS, and SSB is periodically and continuously transmitted. That is, the UE measures the periodically transmitted SSB of the candidate cell to obtain the L1 measurement result. In other words, the UE receives the pre-configured SSB, and the candidate cell side immediately starts transmitting the SSB. The UE can measure the RS at any time based on the RS information in the received LTM configuration.

[0287] Intra-CU LTM: The source cell and the candidate cell are under the same CU (i.e. in the same base station). Further, it includes intra-DU and inter-DU scenarios. Intra-DU means that the source cell and the candidate cell are under the same DU; inter-DU scenario means that the source cell and the candidate cell belong to different DUs under the same CU, and there is no interface between the two DUs. All interactions are forwarded through the CU, and the interface between the CU and the DU is F1.

[0288] Inter-CU LTM: The source cell and the candidate cell are under different CUs (different base stations). The two base stations can be CU-DU separated architecture or non-separated architecture, and the interface between the two base stations is Xn.

[0289] In the subsequent discussion, it is further proposed to use periodic channel state information reference signal (CSI-RS), semi-static CSI-RS, and aperiodic CSI-RS as the measurement RS. Unlike SSB, semi-static and aperiodic CSI-RS are not continuously transmitted. That is, after the UE is pre-configured with RS information, the candidate cell side may start transmitting the RS at a certain time, and the UE does not know when the candidate cell transmits the measurement RS, which will cause the UE to also be unclear about when to start measurement. If the measurement starts too early, it will cause unnecessary interruption of the UE (because the connection with the source node or the serving node needs to be interrupted, and the RS measurement of the candidate cell needs to be performed), and if the measurement starts too late, it may cause waste of resources on the candidate cell side. Since the UE does not establish a connection with the candidate cell, but establishes a direct connection with the serving cell, the candidate node cannot directly notify the UE of the activation and / or deactivation state of its current RS, and since the candidate node does not have the state information of the UE, the candidate node also does not know when the RS should be activated and / or deactivated. Therefore, how to unify the time of transmitting the RS by the candidate cell and starting the measurement by the UE needs to be solved, otherwise it may cause measurement failure or waste of power consumption of the UE.

[0290] And for network energy saving, the network considers transmitting SSB and / or periodic CSI-RS on demand, in the case of supporting on-demand transmission of SSB and / or periodic CSI-RS by the candidate cell, if the UE continuously performs related measurement according to the current LTM mechanism, it will cause unnecessary power consumption, and when the candidate cell supports the energy saving mode, how to notify the UE to start measurement or stop related measurement needs to be solved.

[0291] 2. CSI-RS transmission

[0292] Periodic CSI-RS: After the radio resource control (RRC) entity configures the periodic CSI resource (CSI-resource) parameter, it will take effect immediately, and the cell transmits the CSI-RS periodically.

[0293] Aperiodic CSI-RS: Currently, only the serving cell transmits aperiodic CSI-RS, the network side notifies the UE to activate the aperiodic CSI-RS through downlink control information (DCI), and the UE receives the CSI-RS for measurement according to the specified time after receiving the DCI. The network side only temporarily transmits the CSI-RS and does not transmit it periodically.

[0294] Semi-static CSI-RS: Currently only supports the serving cell to send semi-static CSI-RS, the serving cell activates and / or deactivates the CSI-RS through the MAC CE, and the CSI-RS is sent according to the configured period after being activated, and the UE measures periodically after the CSI-RS is activated.

[0295] Currently, only the RS under the candidate node can be configured to the source node and the UE, and after the configuration is completed, the UE starts to measure the RS, that is, all RSs are activated by default; in addition, the current mechanism only supports the cell to activate and / or deactivate the RS in the cell, and does not support activating and / or deactivating the RS in other nodes. In the LTM scenario, when the UE needs to measure the RS under the candidate cell, the RS under other nodes may also be activated or deactivated. Therefore, how does the source node know the activation and / or deactivation state of the RS under other nodes to ensure that the UE can be triggered to perform measurement or stop measurement in time, and there is currently no solution.

[0296] Embodiments of the present disclosure provide an information processing method and device, a network node and a terminal, to solve the problem that there is currently no solution to how to ensure fast cell switching and reduce resource occupation and waste when other RSs except periodic SSB are used as measurement RS. The method and device (or network node or terminal) are based on the same application concept, and since the principles of the method and device (or network node or terminal) for solving the problem are similar, the implementation of the device and the method can be mutually referred to, and the repeated parts will not be described again.

[0297] As shown in FIGS. 1A and 1B, embodiments of the present disclosure provide an information processing method, comprising the following steps:

[0298] Step 11A: The candidate node receives the first information sent by the serving node, and the candidate node determines the activated and / or deactivated first reference signal according to the first information, and / or performs resource and / or access scheduling according to the first information;

[0299] Or,

[0300] Step 11B: The candidate node sends second information to the serving node; wherein the second information is used to indicate the activated and / or deactivated first reference signal.

[0301] In some embodiments, the first information can be used to indicate that the candidate node activates and / or deactivates the first reference signal, and / or indicates that the candidate node performs resource and / or access scheduling. Alternatively, the first information can include information related to the activation and / or deactivation of the first reference signal by the candidate node, and / or information related to the resource and / or access scheduling by the candidate node.

[0302] For example, the first information can be used to indicate that the candidate node activates and / or deactivates the first reference signal, or the first information can contain information related to the candidate node activating and / or deactivating the first reference signal, specifically, the serving node can determine the first reference signal that needs to be activated and / or deactivated by the candidate node, and notify or instruct the candidate node through the first information, and the candidate node activates and / or deactivates the corresponding first reference signal according to the notification or instruction of the serving node. Alternatively, the serving node can provide the candidate node with relevant information for determining the first reference signal to be activated and / or deactivated through the first information, and the candidate node determines the first reference signal to be activated and / or deactivated. Alternatively, the serving node can provide the candidate node with its suggestion of the first reference signal to be activated and / or deactivated through the first information, and the candidate node decides the first reference signal to be activated and / or deactivated, and the like, which are not limited in the embodiments of the present disclosure.

[0303] In some embodiments, the second information can be used to indicate that the candidate node determines the first reference signal to be activated and / or deactivated, or the second information can contain information related to the candidate node determining the first reference signal to be activated and / or deactivated, and the like.

[0304] For example, the candidate node can determine the first reference signal to be activated and / or deactivated, and notify the serving node through the second information, so that the serving node can know the first reference signal to be activated and / or deactivated by the candidate node.

[0305] In some embodiments, the first reference signal includes but is not limited to: SSB (such as periodic SSB, on-demand SSB, etc.), CSI-IS (such as periodic CSI-IS, aperiodic CSI-IS, semi-static CSI-IS, etc.), CSI interference measurement (CSI-IM), and the like.

[0306] In the embodiments of the present disclosure, the candidate node can determine the activated and / or deactivated first reference signal according to the first information sent by the serving node, and / or perform resource and / or access scheduling according to the first information. Alternatively, the candidate node sends second information for indicating the activated and / or deactivated first reference signal to the serving node, so that the candidate node and the serving node can have consistent understanding of the activated and / or deactivated first reference signal of the candidate node, and the serving node can trigger the terminal to perform measurement or stop measurement in time based on the known activation and / or deactivation of the first reference signal of the candidate node, so as to ensure fast cell switching. In addition, the candidate node can also perform resource and / or access scheduling based on the first information, so as to balance the reserved resources and reduce resource occupation and waste caused by continuous reservation of access resources, on the basis of ensuring fast cell switching. That is, the embodiments of the present disclosure can realize fast cell switching and reduce resource occupation and waste when other RSs except periodic SSB are used as measurement RSs.

[0307] In some embodiments, the first information or the second information comprises at least one of the following:

[0308] The first indication information is used for indicating the first reference signal. For example, the first indication information sent by the serving node to the candidate node can be used for indicating that the serving node determines that the candidate node needs to activate and / or deactivate the first reference signal, or is used for indicating that the serving node suggests the candidate node to activate and / or deactivate the first reference signal. For another example, the first indication information sent by the candidate node to the serving node can be used for notifying the serving node of the first reference signal determined to be activated and / or deactivated by the candidate node, and the like.

[0309] The first activation indication information is used for indicating to activate the first reference signal. For example, the first activation indication information can be used for indicating that all the first reference signals indicated by the first indication information are in the activated state. For example, the first indication information indicates that the first reference signal comprises RS1, RS2, RS3 and RS4, and the first activation indication information can be used for indicating that RS1, RS2, RS3 and RS4 are all in the activated state. Alternatively, the first activation indication information can be used for indicating that part of the first reference signals indicated by the first indication information are in the activated state. For example, the first indication information indicates that the first reference signal comprises RS1, RS2, RS3 and RS4, and the first activation indication information can be used for indicating that RS1 and RS2 are in the activated state, and the like. Alternatively, if the first activation indication is included in the first information or the second information, it means that the corresponding first reference signal is activated, and the embodiments of the present disclosure are not limited thereto.

[0310] The first deactivation indication information is used for indicating deactivation of the first reference signal; for example, the first deactivation indication information can be used for indicating that all the first reference signals indicated by the first indication information are in a deactivation state, such as the first indication information indicating that the first reference signal includes RS1, RS2, RS3, RS4, etc., and the first deactivation indication information can be used for indicating that RS1, RS2, RS3, and RS4 are all in an activation state; or the first deactivation indication information can be used for indicating that part of the first reference signals indicated by the first indication information are in a deactivation state, such as the first indication information indicating that the first reference signal includes RS1, RS2, RS3, RS4, etc., and the first deactivation indication information can be used for indicating that RS3 and RS4 among them are in an activation state, etc.; or if the first deactivation indication is included in the first information or the second information, it indicates deactivation of the corresponding first reference signal, etc. The embodiments of the present disclosure are not limited thereto.

[0311] Time information of activating and / or deactivating the first reference signal; for example, the time information can be the effective time of activating the first reference signal, and / or the effective time of deactivating the first reference signal, that is, the time information can be used for indicating when to activate and / or deactivate the first reference signal.

[0312] State information of the terminal; for example, probability information that the terminal can or can not access the candidate node, such as indicating that the terminal is highly likely not to access the candidate node in a short time through the state information, or the terminal has approached the candidate node and is highly likely to access the candidate node, etc. The embodiments of the present disclosure are not limited thereto.

[0313] L1 beam measurement result;

[0314] Beam information associated with the L1 beam measurement result;

[0315] Second indication information used for indicating the requirement of activating and / or deactivating the first reference signal; for example, the requirement of activating and / or deactivating the first reference signal can also be referred to as the purpose or behavior of activating and / or deactivating the first reference signal, etc., such as the candidate node belonging to an energy-saving network, requesting the energy-saving network to send SSB or send CSI-RS or notifying the candidate cell that it can enter an energy-saving mode and stop sending a certain type of reference signal, etc. The embodiments of the present disclosure are not limited thereto.

[0316] Type information of the first reference signal; for example, the type of the first reference signal includes but is not limited to SSB (such as periodic SSB, on-demand SSB, etc.), CSI-IS (such as periodic CSI-IS, aperiodic CSI-IS, semi-static CSI-IS, etc.), CSI-IM, etc.

[0317] For example, the first information can include, but is not limited to, at least one of the following: first activation indication information, first deactivation indication information, time information of activating and / or deactivating the first reference signal, state information of the terminal, L1 beam measurement result, beam information associated with the L1 beam measurement result, second indication information, and type information of the first reference signal.

[0318] For example, the second information can include, but is not limited to, at least one of the following: first activation indication information, first deactivation indication information, time information of activating and / or deactivating the first reference signal, state information of the terminal, second indication information, and type information of the first reference signal.

[0319] In some embodiments, after the candidate node receives the first information sent by the serving node, the method further includes:

[0320] The candidate node sends first response information to the serving node.

[0321] The first response information is used to indicate that the candidate node confirms the activated and / or deactivated first reference signal, and / or the first response information is used to indicate whether the candidate node rejects the request or suggestion of the serving node to activate and / or deactivate the first reference signal.

[0322] For example, when the first information is used to indicate that the candidate node determines to activate and / or deactivate the first reference signal, and / or is used to indicate that the serving node suggests the candidate node to activate and / or deactivate the first reference signal, or the first information contains the case that the candidate node determines to activate and / or deactivate the first reference signal, and / or contains the case that the serving node suggests the candidate node to activate and / or deactivate the first reference signal, the candidate node can send the first response information to the serving node to notify the serving node of its confirmation of the activated and / or deactivated first reference signal, and / or whether to reject the request or suggestion of the serving node to activate and / or deactivate the first reference signal. In this way, the serving node can know the confirmation of the activated and / or deactivated first reference signal by the candidate node, so as to trigger the terminal to perform measurement or stop measurement in time, thereby ensuring fast cell switching.

[0323] For example, when the first information is used to indicate that the candidate node determines to activate and / or deactivate the first reference signal, or the first information contains the case that the candidate node determines to activate and / or deactivate the first reference signal, the candidate node can send the first response information to the serving node to feed back its decision to activate and / or deactivate the first reference signal.

[0324] For another example, in a case where the first information is used to indicate that the serving node suggests the candidate node to activate and / or deactivate the first reference signal, or the first information contains the first reference signal suggested by the serving node for the candidate node to activate and / or deactivate, the candidate node can send first response information to the serving node to notify the serving node of acceptance or rejection of the first reference signal requested or suggested by the serving node to activate and / or deactivate. Optionally, the candidate node can accept or reject all the first reference signal requested or suggested by the serving node to activate and / or deactivate, or can accept or reject part of the first reference signal requested or suggested by the serving node to activate and / or deactivate, and the embodiments of the present disclosure are not limited thereto.

[0325] In some embodiments, the first response information comprises at least one of:

[0326] Third indication information used to indicate confirmation of the first reference signal to be activated and / or deactivated; for example, in a case where the candidate node decides to activate and / or deactivate the first reference signal, the candidate node can notify the serving node of the determination of the first reference signal to be activated and / or deactivated by the third indication information, that is, inform the serving node of which first reference signal to be activated and / or deactivated.

[0327] Second activation indication information used to indicate confirmation of the first reference signal to be activated; for example, the second activation indication information can be used to indicate that the candidate node confirms that all or part of the first reference signal suggested or requested by the serving node to be activated is in an activated state (that is, the second activation indication information can be used to indicate that all or part of the first reference signal indicated by the first indication information in the first information sent by the serving node is in an activated state); or the second activation indication information can be used to indicate that the candidate node confirms that all the first reference signal indicated by the third indication information is in an activated state, such as the third indication information indicating that the first reference signal includes RS1, RS2, RS3, RS4, etc., and the second activation indication information can be used to indicate that the candidate node confirms that RS1, RS2, RS3, and RS4 are all in an activated state; or the second activation indication information can be used to indicate that the candidate node confirms that part of the first reference signal indicated by the third indication information is in an activated state, such as the third indication information indicating that the first reference signal includes RS1, RS2, RS3, and RS4, and the second activation indication information can be used to indicate that the candidate node confirms that RS1 and RS2 are in an activated state; or if the second activation indication is contained in the first response information, it indicates that the corresponding first reference signal is activated, and the embodiments of the present disclosure are not limited thereto.

[0329] Time information of activation and / or deactivation of the first reference signal; for example, the time information can be the effective time of the candidate node confirming activation of the first reference signal, and / or the effective time of confirming deactivation of the first reference signal, that is, the time information can be used to indicate when the candidate node activates and / or deactivates the first reference signal.

[0330] Fourth indication information, used to indicate whether the candidate node enters the energy saving mode; for example, the fourth indication information can use 1 bit to indicate whether the candidate node enters the energy saving mode, such as the value of the 1 bit being "1" indicating yes and the value being "0" indicating no, or the value of the 1 bit being "0" indicating yes and the value being "1" indicating no, etc.; or it can also be that when the fourth indication information is included in the first response information, it indicates that the candidate node enters the energy saving mode, and correspondingly, if the first response information does not include the fourth indication information, it indicates that the candidate node does not enter the energy saving mode; or it can also be that when the fourth indication information is included in the first response information, it indicates that the candidate node does not enter the energy saving mode, and correspondingly, if the first response information does not include the fourth indication information, it indicates that the candidate node enters the energy saving mode, and the embodiments of the present disclosure are not limited thereto.

[0331] Type information of the first reference signal; for example, the type of the first reference signal includes but is not limited to: SSB (such as periodic SSB, on-demand SSB, etc.), CSI-IS (such as periodic CSI-IS, aperiodic CSI-IS, semi-static CSI-IS, etc.), CSI-IM, etc.

[0332] Fifth indication information for indicating whether to reject the suggestion or request of activating and / or deactivating the first reference signal; for example, the fifth indication information can be used to indicate whether the candidate node rejects all the first reference signals suggested or requested by the serving node to be activated and / or deactivated, or can be used to indicate whether the candidate node rejects or accepts part of the first reference signals suggested or requested by the serving node to be activated and / or deactivated, etc. For example, the fifth indication information can use 1 bit to indicate whether the candidate node rejects the first reference signal suggested or requested by the serving node to be activated and / or deactivated, such as the value of the 1 bit being "1" indicating yes, and the value being "0" indicating no, or the value of the 1 bit being "0" indicating yes, and the value being "1" indicating no, etc.; or it can also be that when the fifth indication information is included in the first response information, it indicates that the candidate node rejects the first reference signal suggested or requested by the serving node to be activated and / or deactivated, and correspondingly, if the fifth indication information is not included in the first response information, it indicates that the candidate node accepts the first reference signal suggested or requested by the serving node to be activated and / or deactivated; or it can also be that when the fifth indication information is included in the first response information, it indicates that the candidate node accepts the first reference signal suggested or requested by the serving node to be activated and / or deactivated, and correspondingly, if the fifth indication information is not included in the first response information, it indicates that the candidate node rejects the first reference signal suggested or requested by the serving node to be activated and / or deactivated, etc. The embodiments of the present disclosure are not limited thereto.

[0333] In some embodiments, the type of the first reference signal indicated by the first information is the same as the type of the first reference signal indicated by the first response information; or the type of the first reference signal indicated by the first information is different from the type of the first reference signal indicated by the first response information.

[0334] For example, the first information sent by the serving node to the candidate node indicates that the type of the first reference signal is CSI-RS (or the first information carries CSI-RS related information requested or suggested by the candidate node to be activated and / or deactivated), the candidate node determines the first reference signal to be activated and / or deactivated based on the CSI-RS related information, and the type of the first reference signal is CSI-RS, and indicates in the first response information that the type of the first reference signal is CSI-RS (or carries the CSI-RS related information to be activated and / or deactivated), etc., that is, the type of the first reference signal indicated by the first information is the same as the type of the first reference signal indicated by the first response information.

[0335] For example, the first information sent by the serving node to the candidate node indicates that the type of the first reference signal is SSB (or the first information carries SSB related information), the candidate node determines that the type of the activated and / or deactivated first reference signal is CSI-RS based on the SSB related information, and the candidate node can indicate in the first response information that the type of the first reference signal is CSI-RS (or carry CSI-RS related information of the activated and / or deactivated first reference signal), and the like, that is, the type of the first reference signal indicated by the first information is different from the type of the first reference signal indicated by the first response information.

[0336] In some embodiments, after the candidate node sends the second information to the serving node, the method further includes:

[0337] The candidate node receives second response information sent by the serving node.

[0338] The second response information is used to indicate that the serving node confirms the activated and / or deactivated first reference signal, and / or the second response information is used to indicate whether the serving node rejects the candidate node's request for the activated and / or deactivated first reference signal.

[0339] For example, the candidate node can send second information to the serving node to indicate that it confirms the activated and / or deactivated first reference signal, that is, the candidate node determines the activated and / or deactivated first reference signal by itself and notifies the serving node, so that the serving node can trigger the UE to perform measurement or stop measurement in time based on the activated and / or deactivated first reference signal determined by the candidate node, to ensure fast cell switching. In some embodiments, when the serving node receives the second information sent by the candidate node, the serving node can feed back second response information to the candidate node to notify the candidate node that it has received the second information, or to confirm the activated and / or deactivated first reference signal indicated by the second information.

[0340] For another example, the candidate node can send the second information to the serving node to request the serving node to confirm the activated and / or deactivated first reference signal, i.e., the candidate node determines the activated and / or deactivated first reference signal by itself and informs the serving node, and the serving node decides whether to allow or accept the activated and / or deactivated first reference signal determined by the candidate node. At this time, the serving node needs to feed back the second response information to the candidate node to inform the candidate node whether to reject the activated and / or deactivated first reference signal requested by the candidate node.

[0651] Embodiment 7:

[0652] The source node sends a request message to the candidate node, carrying the type information of the reference signal and / or the sixth indication information, which can be used to indicate a specific type of reference signal. The type information of the reference signal and / or the sixth indication information can be carried using the Handover request message on the Xn interface, and the candidate cell is requested to provide the specified RS information while requesting the candidate cell to provide the configuration.

[0653] On the F1 interface, the UE context setup / modification request message can be used to provide the specified RS information while requesting the candidate cell to provide the configuration. Unlike the current technology, only SSB is currently supported as RS information, and it is a necessary parameter for supporting LTM, so there is no need for explicit request indication. In this embodiment, additional enhancements are considered, considering that multiple RS information can be used, so the requested RS type is indicated in the request message, and the requested RS type can be one or more, for example: candidate cell 1 is requested to use SSB and CSI-RS as reference signals for UE1.

[0654] The candidate cell can accept or reject according to its own situation, or provide other RS types of RS, etc., for example: the source node requests the candidate cell to provide CSI-RS as the reference signal, but the candidate cell can only provide SSB, at which time the source node's request can be rejected or the source node is only provided with SSB information, etc.

[0655] In this embodiment of the present disclosure, under the premise that the candidate node pre-configures its own RS configuration information for the service node or the source node, the network side interacts with the candidate node and the service node or the source node through the interface to activate and / or deactivate the RS, and notifies the UE to measure or stop the measurement of the specified RS, thereby meeting the requirement of LTM measurement of non-continuous transmission of RS in neighboring cells.
