Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0030] The network device in this application embodiment can be a device for communicating with a terminal device. This network device can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master MeNB, auxiliary SeNB, multi-mode radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof.

This application does not limit the scenario in which the network devices and terminal devices are located.

[0034] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0035] Carrier aggregation (CA) technology

[0036] To meet the demands for increased peak data rates per user and improved system capacity, one of the most direct methods is to increase the system's transmission bandwidth. Therefore, a technique for increasing transmission bandwidth has been introduced into communication systems. Using CA (Carrier Aggregation) technology, multiple (e.g., 2-5) component carriers (CCs) can be aggregated together to increase transmission bandwidth, effectively improving uplink and downlink transmission rates.

[0037] In some implementations, the CCs participating in the aggregation can be carriers that are adjacent in frequency band or carriers that are not adjacent in frequency band.

[0038] In other implementations, CA (Carrier Aggregation) techniques can be categorized according to the range of the aggregated carriers. CA types can be divided into intra-band CA and inter-band CA. As the names suggest, for intra-band CA, the carriers participating in carrier aggregation belong to the same frequency band. For inter-band CA, the carriers participating in carrier aggregation belong to multiple different frequency bands.

[0039] To facilitate understanding, the following section uses scenarios of communication between network devices and terminal devices, as well as side-by-side communication scenarios between terminal devices, as examples to introduce CA technology.

[0040] In communication scenarios between network devices and terminal devices, CA (Carrier Array) is a bandwidth extension technology supported since the LTE-Advanced standard. It can aggregate multiple CCs (Carrier Arrays) together, allowing a single terminal device to receive or transmit them simultaneously. In this scenario, in-band CA can be used when the cell carrier bandwidth is greater than the single carrier bandwidth capability of the terminal device. In this case, the terminal device can use CA to operate in a "wide carrier".

[0041] For example, if a network device supports a 300MHz carrier wave, while a terminal device only supports a maximum carrier wave of 100MHz, then in order to improve the transmission rate between the terminal device and the network device, the terminal device can use the CA method to communicate with the network device using a bandwidth greater than 100MHz.

[0042] In some scenarios, when terminal devices and network devices communicate based on CA, a primary cell (PCell) and a secondary cell (SCell) may be configured simultaneously. The secondary cell may include a primary secondary cell (PSCell).

[0043] DC communication scenario

[0044] The method provided in this application can be used in various DC architectures. For example, dual connectivity between a fourth-generation (4G) communication system and a fifth-generation (5G) communication system, dual connectivity between a 5G communication system and a 4G communication system, dual connectivity between two 5G communication systems, or between a 5G communication system and a future communication system, etc., where the fifth-generation communication system can also be called an NR system.

[0045] In a DC architecture, a terminal device can connect to two cell sets simultaneously. One cell set is called the master cell group (MCG), which includes at least one primary cell (PCell). Optionally, the MCG may also include at least one secondary cell (SCell). The other cell set that the terminal device connects to is called the secondary cell group (SCG), which includes at least one primary secondary cell (PSCell). Optionally, the SCG may also include at least one SCell. It should be noted that since all the cells included in the MCG are usually deployed within a single node, the MCG can also be called the master node (MN) in many scenarios. Since all the cells included in the SCG are usually deployed within a single node, the SCG can also be called the secondary node (SN) in many scenarios. The dual-connectivity architecture of NR-DC is shown in Figure 2. The terminal device connects and communicates with both the MN and the SN simultaneously. The MN and SN are connected through the Xn interface, and the MN is connected to the core network equipment through the NG interface. Optionally, the SN is also connected to the core network equipment through the NG interface.

[0046] The following description uses only the communication system 30 shown in Figure 3 as an example to illustrate the communication system applicable to the embodiments of this application.

[0047] Figure 3 is a schematic diagram of the architecture of the communication system 30 provided in an embodiment of this application. As shown in Figure 3, the communication system 30 may include network device 301, network device 302, network device 305, terminal device 303, and terminal device 304. Figure 3 is only a schematic diagram and does not constitute a limitation on the applicable scenarios of the technical solutions provided in this application.

[0048] The network devices in Figure 3, namely network device 301, network device 302, or network device 305, can be, for example, network device 110 shown in Figure 1. The terminal devices in Figure 3, namely terminal device 303 or terminal device 304, can be, for example, terminal device 120 shown in Figure 1.

[0049] LTM

[0050] To further reduce handover latency and ensure service continuity, LTM (Last Time To Meet) has been introduced in some protocols (e.g., 3GPP R18). For ease of understanding, the LTM process will be explained below with reference to Figure 4.

[0051] As shown in Figure 4, the LTM process can include the LTM preparation phase, the LTM execution phase, and the LTM completion phase.

[0052] During the LTM preparation phase, LTM may include steps S410 to S430.

[0053] In step S410, the terminal device reports the measurement results to the network device. These measurement results can be Layer 3 measurements. The network device can then determine whether to initiate an LTM procedure and trigger candidate cell preparation based on the measurement results reported by the terminal device.

[0054] In step S420, the network device sends a radio resource control (RRC) message containing the LTM configuration (or LTM candidate configuration) to the terminal device. For example, the network device may send an RRC reconfiguration message to the terminal device to indicate the LTM configuration.

[0055] In some embodiments, the LTM configuration sent by the network device to the terminal device may include the LTM configuration corresponding to one or more candidate cells.

[0056] In some embodiments, the terminal device may also store the LTM configuration indicated by the network device.

[0057] In step S430, the terminal device sends a reconfiguration complete message (RRCReconfigurationComplete message) to the network device.

[0058] In some embodiments, referring to steps S440a and S440b, after the terminal device completes the LTM preparation phase, it can perform uplink / downlink synchronization with the candidate cell in advance to shorten the interruption latency during the handover process. This process can be understood as the early synchronization phase.

[0059] During the LTM execution phase, LTM may include steps S450 and S460.

[0060] In step S450, the terminal device performs Layer 1 measurement on each candidate cell and reports the Layer 1 measurement results to the network device.

[0061] In some implementations, after receiving the Layer 1 measurement results reported by the terminal device, the network device can determine the target cell based on the Layer 1 measurement results.

[0062] In step S460, the network device sends a cell handover command to the terminal device to instruct the terminal device to hand over to the target cell. For example, the network device can instruct the terminal device to hand over to the target cell through a medium access control element (MAC CE).

[0063] In some implementations, after receiving a cell handover command, the terminal device can detach from the source cell and apply the target configuration (i.e., apply the configuration of the target cell).

[0064] In some embodiments, if the terminal device does not currently have a valid timing advance (TA) or transmission configuration indicator (TCI) status identifier for the target cell, the terminal device may also execute step S470 during the LTM execution phase. In step S470, the terminal device initiates a random access procedure to the target cell.

[0065] During the LTM completion phase, LTM may include step S480.

[0066] In step S480, the terminal device indicates that LTM is complete. For example, the terminal device may send an indication message that LTM has been successfully completed to the target cell.

[0067] Currently, the measurement process for candidate nodes and / or candidate auxiliary nodes in communication systems takes a long time, resulting in a large handover delay, which may affect the continuity of the communication process.

[0068] In this application embodiment, it is proposed to perform Layer 1 and / or Layer 3 measurements on candidate nodes and / or candidate auxiliary nodes, which helps to reduce the time required for measuring candidate primary nodes and / or candidate auxiliary nodes, helps to shorten switching latency, and ensures service continuity.

[0069] The following describes a wireless communication method according to an embodiment of this application with reference to FIG5. The method shown in FIG5 includes step S510.

[0070] In step S510, the terminal device performs measurements on the candidate primary node and / or candidate secondary node, including layer 1 measurements and / or layer 3 measurements.

[0071] In some implementations, the terminal device performs measurements on the candidate master node, which helps reduce the time required for measuring the candidate master node, shortens the switching latency, and ensures service continuity.

[0072] In some implementations, the terminal device measures the candidate secondary nodes, which helps reduce the time required for measuring the candidate secondary nodes, shortens the handover latency, and ensures service continuity.

[0073] In some implementations, the terminal device performs measurements on both candidate secondary nodes and candidate primary nodes. This helps reduce the time required for measuring these nodes, thus shortening handover latency and ensuring service continuity. Alternatively, the terminal device can perform measurements on both candidate secondary nodes and candidate primary nodes simultaneously, which helps improve the rationality of the handover process.

[0074] In the embodiments of this application, the measurement is not limited. For example, the measurement includes measurements triggered only based on Layer 1. As another example, the measurement includes measurements triggered only based on Layer 3. As yet another example, the measurement includes measurements triggered based on both Layer 1 and Layer 3 (i.e., LTM as described above).

[0075] In some scenarios, measuring candidate primary nodes and / or candidate secondary nodes can be replaced by evaluating candidate primary nodes and / or candidate secondary nodes.

[0076] In some implementations, candidate master nodes can be understood as candidate nodes in the mobility management process. For example, candidate master nodes can include one of the following: candidate PCell, candidate MN, candidate MCG, candidate anchor TRP, candidate PSCell, or candidate SCell. Specifically, a candidate anchor TRP can be a candidate node used to select an anchor TRP in a multi-TRP scenario. A candidate PCell can be a candidate node used to select a PCell. A candidate MN can be a candidate node used to select an MN. A candidate MCG can be a candidate node used to select an MCG.

[0077] In some implementations, candidate auxiliary nodes can be understood as candidate nodes in the mobility management process. For example, candidate auxiliary nodes can include one of the following: candidate PScell, candidate SCell, or candidate TRP. A candidate TRP can be, for example, a TRP that collaborates with the anchor TRP in a multi-TRP scenario. A candidate anchor TRP can be, for example, a candidate node used to select the anchor TRP in a multi-TRP scenario. A candidate PCell can be, for example, a candidate node used to select the PCell. A candidate MN can be, for example, a candidate node used to select the MN. A candidate MCG can be, for example, a candidate node used to select the MCG.

[0078] In some implementations, the above measurement can be triggered by a first condition, which can also be called a triggering condition. That is, step S510 includes: in response to the first condition being met, the terminal device performs measurements on the candidate primary node and / or candidate secondary node.

[0079] In some implementations, the first condition includes one or more of the following: receiving first configuration information; the measurement results of the candidate master node satisfying the second condition.

[0080] Taking the first condition including receiving the first configuration information as an example, alternatively, in response to the terminal device receiving the first configuration information sent by the network device, the terminal device performs measurements on the candidate primary node and / or candidate secondary node.

[0081] In some implementations, the first configuration information is used to configure the terminal device to perform measurements on candidate primary nodes and / or candidate secondary nodes. For example, the first configuration information is used to configure the terminal device to perform measurements on candidate primary nodes. For example, the first configuration information is used to configure the terminal device to perform measurements on candidate secondary nodes. Yet another example is that the first configuration information is used to configure the terminal device to perform measurements on both candidate primary nodes and candidate secondary nodes. See the following description for details.

[0082] In some implementations, the first configuration information includes one of the following: measurement configurations for one or more candidate secondary nodes; measurement configurations for one or more candidate primary nodes; measurement configurations for candidate primary nodes and measurement configurations for one or more candidate secondary nodes.

[0083] Taking the example where the first configuration information includes measurement configurations for one or more candidate secondary nodes, but excludes measurement configurations for one or more candidate primary nodes, it can be understood that the measurements for candidate secondary nodes and the configurations for candidate primary nodes are configured independently. Accordingly, the network device can send second configuration information to the terminal device to configure measurements for one or more candidate primary nodes for the terminal device.

[0084] In this scenario, there may be no association between the candidate primary node and the candidate secondary node. For example, the candidate configuration identifiers associated with the candidate primary node and the candidate secondary node may be different.

[0085] At this point, the terminal device can perform measurements based on both the first configuration information and the second configuration information. One or more nodes obtained from measurements based on the first configuration information can be considered as candidate auxiliary nodes. One or more nodes obtained from measurements based on the second configuration information can be considered as candidate primary nodes.

[0086] Taking the example where the first configuration information includes measurement configurations for one or more candidate primary nodes, but excludes measurement configurations for one or more candidate secondary nodes, it can be understood that the measurements for candidate secondary nodes and the configurations for candidate primary nodes are configured independently. Accordingly, the network device can send third configuration information to the terminal device to configure the measurements for one or more candidate secondary nodes for the terminal device.

[0087] In this scenario, there may be no association between the candidate primary node and the candidate secondary node. For example, the candidate configuration identifiers associated with the candidate primary node and the candidate secondary node may be different.

[0088] At this point, the terminal device can perform measurements based on both the first configuration information and the second configuration information. One or more nodes obtained from measurements based on the first configuration information can be considered as candidate primary nodes. One or more nodes obtained from measurements based on the second configuration information can be considered as candidate secondary nodes.

[0089] The first configuration information includes the measurement configuration of one candidate primary node and the measurement configuration of one or more candidate secondary nodes. In this case, it can be understood that both the measurement for the candidate secondary node and the configuration for the candidate primary node can be configured using the first configuration information. Alternatively, it can be understood that the measurement for the candidate secondary node and the configuration for the candidate primary node are configured together.

[0090] In this scenario, a candidate master node can be associated with one or more candidate slave nodes. For example, the candidate configuration identifier associated with a candidate master node and one or more candidate slave nodes can be the same. For instance, a candidate configuration identifier can be associated with PCell and PSCell. Or, for example, a candidate configuration identifier can be associated with PCell and SCell.

[0091] In this embodiment, the method by which the first configuration information carries the measurement configuration of the candidate master node and the measurement configuration of one or more candidate slave nodes is not limited. In some implementations, the measurement configuration of the candidate master node and the measurement configuration of one or more candidate slave nodes can be carried in the first configuration information through signaling nesting. In this case, it can be understood that the measurement configuration of one or more candidate slave nodes is associated with the measurement configuration of the candidate master node. For example, the measurement configuration of one or more candidate slave nodes can be nested in the measurement configuration of the candidate master node. Of course, in this embodiment, the measurement configuration of the candidate master node and the measurement configuration of one or more candidate slave nodes can also be carried independently in the first configuration information.

[0092] Additionally, it should be noted that the above example uses one candidate master node and one or more candidate auxiliary nodes. Assuming that one candidate master node and one or more candidate auxiliary nodes can be considered a group of nodes, the solution in this application embodiment can also be applied to scenarios with multiple groups of nodes. For example, the first configuration information can configure multiple candidate master nodes and one or more candidate auxiliary nodes associated with each candidate master node.

[0093] Taking the measurement result of a candidate master node satisfying the second condition as an example, that is, if the measurement result of a candidate master node satisfies the second condition, the terminal device performs measurements on the candidate auxiliary nodes associated with the candidate master node. Alternatively, the terminal device can continue to measure both the candidate master node and its associated candidate auxiliary nodes. In this embodiment, the second condition can be used to filter candidate master nodes that meet the conditions, and after a candidate master node meets the conditions, measurements are performed on its associated candidate auxiliary nodes, which helps improve the rationality of measuring candidate master nodes.

[0094] Example 1: The candidate secondary node is PSCell in SCG, and correspondingly, the candidate primary node associated with the candidate secondary node can be PCell. That is, the terminal device can start performing measurements on the PSCell associated with PCell if PCell meets the second condition.

[0095] Example 2: The candidate secondary node is PSCell in SCG, and correspondingly, the candidate primary node associated with the candidate secondary node can be MCG. That is, the terminal device can start performing measurements on SCG if MCG meets the second condition.

[0096] Example 3: The candidate secondary node is PSCell in SN, and correspondingly, the candidate primary node associated with the candidate secondary node can be MN. That is, the terminal device can start performing measurements on SN if MN meets the second condition.

[0097] It should be understood that Examples 1 to 3 can be applied to DC scenarios. Furthermore, the embodiments of this application do not limit the association relationship between candidate primary nodes and candidate secondary nodes in this scenario. In some implementations, if the candidate secondary node is PScell ​​in SCG, then the candidate primary node associated with this candidate secondary node is one of the following: PCell, MN, or MCG.

[0098] In Example 4, the candidate secondary node is SCell, and correspondingly, the candidate primary node associated with the candidate secondary node can be PCell. That is, the terminal device can begin performing measurements on PCell if PCell meets the second condition. It should be understood that Example 4 can be applied to CA (Computer-Aided) scenarios.

[0099] Example 5: The candidate secondary node is the candidate TRP. Correspondingly, the candidate primary node associated with the candidate secondary node can be the anchor TRP (or the currently working TRP). That is to say, the terminal device performs a measurement on the candidate TRP when the anchor TRP (or the currently working TRP) meets the second condition.

[0100] In some implementations, the second condition includes one or more of the following: the measurement result of the candidate master node is greater than the first threshold; the measurement result of the candidate master node is higher than the measurement result of the service node; the measurement result of the candidate master node is higher than the measurement result of the service node, and the difference between the measurement result of the candidate master node and the measurement result of the service node is greater than the second threshold.

[0101] Taking the second condition, which includes the measurement result of the candidate master node being greater than the first threshold, as an example, if the measurement result of the candidate master node meets the second condition (i.e., the measurement result of the candidate master node is greater than the first threshold), it indicates that the communication conditions of the candidate master node are good. At this time, the candidate master node can continue to be measured to determine whether to communicate based on the candidate master node.

[0102] In some implementations, the first threshold can be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.

[0103] Taking the second condition, which includes the measurement result of the candidate master node being higher than that of the service node, as an example, if the measurement result of the candidate master node meets the second condition (i.e., the measurement result of the candidate master node is higher than that of the service node), it indicates that the communication conditions of the candidate master node are better. At this time, the candidate master node can continue to be measured to determine whether to communicate based on the candidate master node.

[0104] In some implementations, a service node can be understood as the currently active node. For example, service nodes include one or more of the following: PCell, PScell, SCell, and TRP.

[0105] Taking the second condition, which includes the candidate master node's measurement result being higher than the service node's measurement result, and the difference between the candidate master node's measurement result and the service node's measurement result being greater than the second threshold, as an example, it means that if the candidate master node meets the second condition, it indicates that the candidate master node's measurement result is significantly better than the service node's measurement result. Compared to the scheme of immediately measuring the candidate master node when its measurement result is slightly higher than the service node's measurement result, this helps to avoid frequently measuring the candidate master node, thereby improving the rationality of measuring the candidate master node.

[0106] In some implementations, a service node can be understood as the currently active node. For example, service nodes include one or more of the following: PCell, PScell, SCell, and TRP.

[0107] In addition, in this embodiment of the application, the second threshold may be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.

[0108] It should be noted that the above only introduces the possible implementations of the first condition. The first condition can also be implemented in other ways. In some implementations, the first condition may include poor channel quality of the serving node. For example, the measurement of candidate TRPs begins when the channel quality of the serving TRP is not good enough.

[0109] It should be noted that the two implementation methods of the first condition described above can be used independently or in combination. Taking the combination as an example, if the terminal device receives the first configuration information and the measurement results of the candidate primary node meet the second condition, the terminal device performs measurements on the candidate primary node and / or the candidate secondary node. Of course, taking the terminal device receiving the first configuration information as the first condition as an example, if the terminal device receives the first configuration information, it can be understood that it performs measurements on the candidate primary node and / or the candidate secondary node.

[0110] In some implementations, the terminal device can determine whether to stop performing measurements on the candidate secondary node based on a third condition. That is, the method also includes: in response to the satisfaction of the third condition, the terminal device stops performing measurements on the candidate secondary node.

[0111] In some implementations, the third condition includes one or more of the following: the measurement result of the service node is greater than the third threshold; the throughput of the service node is greater than the fourth threshold; the measurement result of the candidate master node is lower than the measurement result of the service node; the measurement result of the candidate master node is lower than the measurement result of the service node, and the difference between the measurement result of the candidate master node and the measurement result of the service node is greater than the fifth threshold.

[0112] Taking the third condition, which includes the measurement result of the service node being greater than the third threshold, as an example, if the measurement result of the service node is greater than the third threshold, it indicates that the communication conditions of the service node are good. At this time, the measurement of the candidate auxiliary node can be stopped, and communication can continue based on the service node.

[0113] In some implementations, the third threshold can be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.

[0114] In some implementations, a service node can be understood as the currently active node. For example, a service node can include one or more of the following: PCell, PScell, SCell, and TRP.

[0115] Taking the third condition, which includes the service node's throughput being greater than the fourth threshold, as an example, or in other words, if the service node's throughput meets the fourth threshold, it indicates that the service node's communication conditions are good. In this case, the measurement of the candidate auxiliary node can be stopped, and communication can continue based on the service node.

[0116] In some implementations, the fourth threshold can be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.

[0117] In some implementations, a service node can be understood as the currently active node. For example, a service node can include one or more of the following: PCell, PScell, SCell, and TRP.

[0118] Taking the third condition, which includes the measurement result of the candidate primary node being lower than that of the service node, as an example, in this case, the measurement result of the candidate primary node is worse than that of the service node. At this time, the measurement of the candidate secondary node can be stopped, and communication can continue based on the service node.

[0119] In some implementations, a service node can be understood as the currently active node. For example, a service node can include one or more of the following: PCell, PScell, SCell, and TRP.

[0120] Taking the third condition, which includes the candidate master node's measurement result being lower than the service node's measurement result, and the difference between the candidate master node's measurement result and the service node's measurement result being greater than the fifth threshold, as an example, it shows that the service node's measurement result is significantly better than the candidate master node's measurement result. Therefore, the measurement of the candidate auxiliary node can be stopped, and communication can continue based on the service node.

[0121] In some implementations, the fifth threshold can be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.

[0122] In some implementations, a service node can be understood as the currently active node. For example, a service node can include one or more of the following: PCell, PScell, SCell, and TRP.

[0123] The foregoing described the measurements of candidate primary nodes and / or candidate secondary nodes in the embodiments of this application. The following describes the measurement results in the embodiments of this application.

[0124] In some implementations, the measurement results include one or more of the following: measurement results of one or more candidate primary nodes; measurement results of one or more candidate secondary nodes; and measurement results of service nodes.

[0125] In some implementations, the candidate master node associated with the measurement result is determined from multiple candidate master nodes based on priority. Here, the candidate master node associated with the measurement result can be understood as one whose measurement result includes the measurement result of that candidate master node. For example, the candidate master node associated with the measurement result is a higher-priority candidate master node among multiple candidate master nodes.

[0126] In some implementations, the priority of candidate master nodes can be configured by the network device for the terminal device.

[0127] In some implementations, the candidate auxiliary node associated with the measurement result is determined from multiple candidate auxiliary nodes based on priority. Here, a candidate auxiliary node associated with the measurement result can be understood as a measurement result containing the measurement result of that candidate auxiliary node. For example, the candidate auxiliary node associated with the measurement result is a candidate auxiliary node with higher priority among multiple candidate auxiliary nodes.

[0128] In some implementations, the priority of candidate secondary nodes can be configured by the network device for the terminal device.

[0129] Taking SCell as an example of candidate secondary nodes, assuming that the maximum number of SCells supported by the terminal device is 32, the network device can configure different priorities for SCells for the terminal device. Accordingly, the terminal device can select which SCell measurement results need to be reported from multiple SCells based on the priority of the SCell.

[0130] In some implementations, the candidate auxiliary node associated with the measurement result is the active candidate auxiliary node among multiple candidate auxiliary nodes.

[0131] In some implementations, for an active candidate secondary node, if the measurement result of the candidate secondary node is lower than a threshold, the reporting of the measurement result of the candidate secondary node is triggered. Taking the candidate secondary node as a candidate SCell as an example, if a candidate SCell is set to an active state in the candidate cell configuration, then the terminal device only needs to trigger the reporting of the measurement result of that SCell when the measurement result of that SCell is lower than the threshold.

[0132] In some implementations, for candidate secondary nodes in an inactive state, if the measurement result of the candidate secondary node is higher than a threshold, the reporting of the measurement result of the candidate secondary node is triggered. Taking candidate SCells as an example, if a candidate SCell is set to an inactive state in the candidate cell configuration, then the terminal device only needs to trigger the reporting of the measurement result of that SCell when the measurement result of that SCell is higher than the threshold.

[0133] In some implementations, the candidate master node associated with the measurement result is the active candidate master node among multiple candidate master nodes.

[0134] In some implementations, if the measurement result of a candidate master node in an active state is lower than a threshold, the candidate master node is triggered to report its measurement result.

[0135] In some implementations, if the measurement result of a candidate master node that is inactive is higher than a threshold, the candidate master node is triggered to report its measurement result.

[0136] In some implementations, the measurement results of the candidate master node include one or more of the following: cell-level measurement results; one or more beam measurement results; identification information of the candidate master node; information indicating the triggering conditions for reporting measurement results; information indicating whether the candidate master node meets the conditions; information indicating whether the candidate master node meets the measurement threshold; and information indicating whether the candidate master node meets the measurement event.

[0137] In some implementations, the measurement results of candidate auxiliary nodes include one or more of the following: cell-level measurement results; one or more beam measurement results; identification information of candidate auxiliary nodes; information indicating the triggering conditions for reporting measurement results; information indicating whether candidate auxiliary nodes meet the conditions; information indicating whether candidate auxiliary nodes meet the measurement threshold; and information indicating whether candidate auxiliary nodes meet the measurement event.

[0138] In some implementations, the measurement results of the serving node include one or more of the following: cell-level measurement results; one or more beam measurement results; identification information of the serving node; information indicating the triggering conditions for reporting measurement results; information indicating whether the serving node meets the conditions; information indicating whether the serving node meets the measurement threshold; and information indicating whether the serving node meets the measurement event.

[0139] In the embodiments of this application, the measurement results of the beam are not limited. For example, the beam measurement results include the measurement results of the synchronization signal block (SSB) and / or the measurement results of the channel status indicator reference signal (CSI-RS).

[0140] The measurement results in the embodiments of this application have been described above. The reporting method of the measurement results in the embodiments of this application is described below.

[0141] In some implementations, the above method further includes: the terminal device sending the measurement results to the network device, and the measurement results being reported based on one of the following methods: periodic reporting; non-periodic reporting; or reporting based on a fourth condition.

[0142] Taking the reporting of measurement results based on the fourth condition as an example, that is, if the fourth condition is met, the terminal device sends the measurement results to the network device.

[0143] In some implementations, the fourth condition is associated with one or more of the following: the measurement results of the candidate primary node; the measurement results of the candidate secondary node; and the measurement results of the service node.

[0144] Taking the association of the fourth condition with the measurement results of the candidate master node as an example, or in other words, the fourth condition is a condition specific to the measurement results of the candidate master node. In this case, if the measurement results of the candidate master node meet the fourth condition, the terminal device sends the measurement results to the network device.

[0145] For example, if the measurement results of the candidate master node meet the fourth condition, the terminal device sends the measurement results of the candidate master node and the measurement results of the candidate slave node to the network device.

[0146] For example, if the measurement results of the candidate primary node meet the fourth condition, the terminal device sends the measurement results of the candidate primary node, the measurement results of the candidate secondary node, and the measurement results of the service node to the network device.

[0147] In this application embodiment, the fourth condition is not limited. For example, the fourth condition may include the measurement result of the candidate master node being greater than a threshold (also known as the "sixth threshold"), wherein the threshold may be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device. As another example, the fourth condition may include the measurement result of the candidate master node being better than the measurement result of the serving node.

[0148] Taking the association of the fourth condition with the measurement results of the candidate auxiliary node as an example, or in other words, the fourth condition is a condition specific to the measurement results of the candidate auxiliary node. In this case, if the measurement results of the candidate auxiliary node satisfy the fourth condition, the terminal device sends the measurement results to the network device.

[0149] In some implementations, the measurement results may include the measurement results of candidate auxiliary nodes, wherein the measurement results of candidate auxiliary nodes may only include the measurement results that satisfy the fourth condition. Of course, in the embodiments of this application, the measurement results of candidate auxiliary nodes may include the measurement results of all candidate auxiliary nodes.

[0150] For example, if the measurement results of the candidate secondary node meet the fourth condition, the terminal device sends the measurement results of the candidate secondary node to the network device. In this case, it can be understood that the measurement results of the candidate secondary node are reported independently. The measurement results of the candidate secondary node may only include the measurement results that meet the fourth condition.

[0151] For example, if the measurement results of the candidate secondary node meet the fourth condition, the terminal device sends the measurement results of the candidate primary node and the candidate secondary node to the network device.

[0152] For example, if the measurement results of the candidate secondary node meet the fourth condition, the terminal device sends the measurement results of the candidate primary node, the measurement results of the candidate secondary node, and the measurement results of the service node to the network device.

[0153] In this application embodiment, the fourth condition is not limited. For example, the fourth condition may include the measurement result of the candidate secondary node being greater than a threshold (also known as the "seventh threshold"), wherein the threshold may be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device. As another example, the fourth condition may include the measurement result of the candidate secondary node being better than the measurement result of the serving node.

[0154] Taking the association of the fourth condition with the measurement results of the service node as an example, or in other words, the fourth condition is a condition specific to the measurement results of the service node. In this case, if the measurement results of the service node meet the fourth condition, the terminal device sends the measurement results to the network device.

[0155] For example, if the measurement results of the service node meet the fourth condition, the terminal device sends the measurement results of the candidate primary node and the measurement results of the candidate secondary node to the network device.

[0156] For example, if the measurement results of the service node meet the fourth condition, the terminal device sends the measurement results of the candidate primary node, the measurement results of the candidate secondary node, and the measurement results of the service node to the network device.

[0157] In this application embodiment, the fourth condition is not limited. For example, the fourth condition may include the service node's measurement result being greater than a threshold (also known as the "eighth threshold"), or the service node's measurement result being less than a threshold (also known as the "ninth threshold"). The threshold may be determined based on one or more of the following: predefined information, preconfiguration information, or configuration information sent by the network device. For example, the fourth condition may also include the service node's measurement result being lower than the service node's measurement result.

[0158] Taking the association of the fourth condition with the measurement results of the candidate primary node and the candidate secondary node as an example, or in other words, the fourth condition is a condition for the measurement results of the candidate primary node and the candidate secondary node. In this case, if the measurement results of the candidate primary node and the candidate secondary node both satisfy the fourth condition, the terminal device sends the measurement results to the network device.

[0159] For example, if the measurement results of both the candidate primary node and the candidate secondary node satisfy the fourth condition, the terminal device sends the measurement results of both the candidate primary node and the candidate secondary node to the network device.

[0160] For example, if the measurement results of the candidate primary node and the candidate secondary node both satisfy the fourth condition, then the terminal device sends the measurement results of the candidate primary node, the candidate secondary node, and the service node to the network device.

[0161] In this application embodiment, the fourth condition is not limited. For example, the fourth condition may include the measurement results of both the candidate primary node and the candidate secondary node being greater than a threshold, wherein the threshold may be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.

[0162] For example, the fourth condition may include the measurement result of the candidate primary node being greater than threshold 1 and the measurement result of the candidate secondary node being greater than threshold 2, wherein threshold 1 and threshold 2 are different, and threshold 1 and / or threshold 2 may be determined based on one or more of the following: predefined information, preconfiguration information, and configuration information sent by the network device.

[0163] For example, the fourth condition may include the measurement results of the candidate primary node and the measurement results of the candidate secondary node being better than the measurement results of the service node.

[0164] In this embodiment, the content of the measurement results is not limited. In some implementations, the measurement results may include the measurement results of the candidate primary node that satisfy the fourth condition, and the measurement results of the candidate secondary node that satisfy the fourth condition. In other implementations, the measurement results may include the measurement results of other candidate secondary nodes associated with the candidate primary node, and these other candidate secondary nodes may be nodes other than the aforementioned candidate secondary nodes (e.g., the candidate secondary nodes associated with the candidate primary node configured in the first configuration information).

[0165] It should be noted that the conditions involved in the embodiments of this application (e.g., any one of the first to fourth conditions) can be used for condition evaluation. In some implementations, condition evaluation can be based on cell-level measurement results. In other implementations, condition evaluation can be based on the measurement results of at least one beam, wherein at least one beam can be determined based on the currently operating beam, or at least one beam can be the beam with the best quality among the currently operating beams.

[0166] In the embodiments of this application, the beam may be associated with one or more of the following: SSB; CSI-RS; tracking reference signal (TRS); sounding reference signal (SRS); TCI state.
