Description

Measurement methods, communication equipment and storage media Technical Field

[0001] This application relates to the field of communication technology, specifically to a measurement method, communication device, and storage medium. Background Technology

[0002] While 5G has begun global commercial use, geographical conditions and business models limit its ability to guarantee network coverage in remote ocean and land areas. To overcome these terrain limitations, integrating satellite communication with terrestrial networks to create a seamless, integrated global network encompassing land, sea, air, and space has become a hot research topic in academia and industry. Currently, non-terrestrial networks (NTNs) focus on integrating satellite communication with 5G to address key issues in New Radio (NR) support for NTNs. Future integrated space-air-space networks will primarily focus on deep integration, combining diverse communication platforms to provide broader and more diversified communication services.

[0003] In existing 5G networks, to reduce overhead and interference from reference signals from other cells, 5G (NR) networks remove the Cell-Specific Reference Signal (CRS) and introduce a Synchronization Signal Block (SSB) for cell signal measurement. This synchronization block consists of the SS and PBCH, and its transmission period is longer than that of the CRS. Signal interference issues arise during the measurement process. Summary of the Invention

[0029] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present application, not the entire structure.

[0030] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processes, many of these steps can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the steps can be rearranged. A process can be terminated when its operation is complete, but it may also have additional steps not included in the figures. A process can correspond to a method, function, procedure, subroutine, subroutine, etc.

[0031] It should be noted that the concepts of "first" and "second" mentioned in the embodiments of this application are only used to distinguish different devices, modules, units or other objects, and are not used to limit the order or interdependence of the functions performed by these devices, modules, units or other objects.

[0032] Furthermore, the embodiments and features described in this application may be combined with each other, unless otherwise specified.

[0033] NTN downlink coverage is constrained by satellite payload constraints. Due to power and link bandwidth limitations, it may not be possible for all beams of a satellite to be active simultaneously. In such scenarios, avoiding interference between beams within different cells / between cells is a pressing issue that needs to be addressed.

[0034] If two adjacent cells use the same SMTC, and the first communication node is located at the boundary between the two adjacent cells, interference problems will occur during the measurement process when receiving reference signals from the two adjacent cells.

[0035] In mobile communication, a terminal (User Equipment, UE) that has entered the connected state will not only continuously measure the serving cell, but also measure neighboring cells according to the network configuration, in case the serving cell signal deteriorates or the cell is switched over for other reasons.

[0036] In a 4G (LTE) network, the base station (eNodeB) continuously transmits CRS, so the UE can measure the signal quality of neighboring cells.

[0037] To reduce overhead and interference from reference signals from other cells, 5G (NR) networks have removed the CRS and introduced the SS / PBCH block (SSB) for cell signal measurement. This synchronization block consists of a synchronization signal (SS) and a physical broadcast channel (PBCH), and its transmission period is longer than that of the CRS. The number of SSBs in a single burst depends on the operating frequency band.

[0038] In the network, the SSB period can be configured for each cell (unit) in 5, 10, 20, 40, 80 or 160 ms; while the UE does not need to periodically measure cell signals like the SSB, and can configure a suitable measurement period according to channel conditions to help avoid unnecessary measurements and reduce UE power consumption.

[0039] The SMTC window period can be set within the SSB broadcast period range, such as 5, 10, 20, 40, 80, or 160 ms, and the window duration can be set to 1, 2, 3, 4, or 5 ms. Figure 1(a) is a schematic diagram of SSB transmission provided by the prior art, and Figure 1(b) is a schematic diagram of SMTC configuration provided by the prior art. As shown in Figure 1(a), the transmission of SSBs on NR cell A is explained, and four SSBs (SSB0, SSB1, SSB2, and SSB3) can be transmitted on cell A.

[0040] Figure 2(a) is another SSB transmission diagram provided by the prior art, and Figure 2(b) is another SMTC configuration diagram provided by the prior art. As shown in Figure 2(a), the transmission of SSB on NR cell B is explained. Eight SSBs (SSB0, SSB1, SSB2, SSB3...SSB7) can be transmitted on cell B.

[0041] By comparing Figure 1(b) and Figure 2(b), different SMTC periods and different SMTC durations can be used for SSB measurement. When the base station notifies the UE of the SMTC measurement window, the UE can detect and measure the SSB within that measurement window and report the measurement results to the base station.

[0042] In view of this, this application provides a measurement method in which a first communication node can determine one or more SMTCs according to the first control information, so as to ensure that the two adjacent cells use different SMTCs even when the first communication node is at the boundary of two adjacent cells, thereby avoiding signal interference between different cells. At the same time, it can also reduce the power consumption of the first communication node and extend the standby time of the first communication node.

[0043] In this embodiment of the application, the first communication node can be a user equipment (UE), and the second communication node can be a network device.

[0044] The UE in this application embodiment can be referred to as a terminal, which can be a mobile terminal, a vehicle-mounted terminal, etc. The UE includes any device that provides voice and / or data connectivity to the user, such as wireless terminal devices, mobile terminal devices, device-to-device (D2D) terminal devices, vehicle-to-everything (V2X) terminal devices, machine-to-machine / machine-type communications (M2M / MTC) terminal devices, Internet of Things (IoT) terminal devices, light UEs, reduced-capability UEs (REDCAP UEs), subscriber units, subscriber stations, mobile stations, remote stations, access points (APs), remote terminals, access terminals, user terminals, user agents, or user devices, etc. It can also refer to user devices in future communication systems, but this patent does not limit this.

[0045] The network devices in this application embodiment can be access network devices, core network devices, or servers, etc. Access network devices can be base stations in terrestrial communication networks or base stations in NTN networks. For example, evolved NodeBs (eNBs), next-generation nodes (gNBs) in NR systems, roadside units (RSUs), centralized units (CUs) and distributed units (DUs) in cloud access network systems, and access network devices in future communication systems. Base stations in NTN networks can include: transparent base stations, regenerate base stations, and other types of base stations. Base stations can be mounted on non-terrestrial or airborne equipment, such as satellites, space stations, or other spacecraft. Core network devices can be Mobility Management Entities (MMEs), Serving Gateways (SGWs), Packet Data Node Gateways (PGWs), Home Subscriber Servers (HSSs) storing user subscription information, Policy and Charging Rule Functions (PCRFs), etc., and can also be core network devices in future communication systems; this application is not limited to these.

[0046] This application provides an example of a measurement method applied to a first communication node, the method comprising:

[0047] Define SMTC, where SMTC is the measurement time configuration for SS / PBCH.

[0048] In one example, the first communication node determines the SMTC, which may include at least one of the following:

[0049] The first communication node selects one or more SMTCs;

[0050] The first communication node uses one or more specified SMTCs.

[0051] In one example, the first communication node selects one or more SMTCs, which may include at least one of the following:

[0052] Choose one or more SMTCs independently;

[0053] Randomly select one or more SMTCs;

[0054] Select one or more SMTCs based on the first control information.

[0055] In one example, the first communication node autonomously selects one or more SMTCs: the first communication node can conduct a comprehensive analysis based on its own situation and autonomously select one or more SMTCs based on the analysis results.

[0056] In one example, the first communication node randomly selects one or more SMTCs: the first communication node can randomly select one or more SMTCs from one or more SMTCs received in advance. The one or more SMTCs received in advance can be one or more SMTCs sent by the second communication node. Furthermore, when the second communication node sends one or more SMTCs, it can be understood that the second communication node sends a set of SMTCs, which can be a set of all SMTCs that the second communication node has pre-generated and sent to the first communication node, and that can be used by the first communication node.

[0057] In one example, the first communication node selects one or more SMTCs based on the first control information: The first communication node can select one or more SMTCs based on one or more pieces of information in the first control information for its use. Specifically, the first communication node can select one or more SMTCs based on at least one of the following: the first communication node's location information, the beam information of the first communication node, the synchronization signal block (SSB) information of the first communication node, the cell information of the first communication node, the first configuration information, or other information.

[0058] In one example, where the first communication node uses one or more specified SMTCs: the second communication node can provide indication information indicating the identifier, name, specific configuration, or other associated information of one or more SMTCs, and send this indication information to the first communication node, so that the first communication node uses one or more SMTCs indicated by the indication information. Furthermore, the first communication node can use all or some of the SMTCs indicated by the indication information.

[0059] In this application, the process of determining one or more SMTCs based on one or more pieces of information in the first control information is described as an example.

[0060] Figure 3 is a flowchart of a measurement method provided in an embodiment of this application. This embodiment is applied to the case of determining the SMTC used by the first communication node. This embodiment can be executed by the first communication node. As shown in Figure 3, this embodiment includes: S110.

[0061] S110. Determine SMTC based on first control information; wherein, the first control information is used to indicate the relevant information on which the SMTC determination is based.

[0062] In this embodiment, determining the SMTC based on the first control information can be understood as determining the SMTC used / adopted by the first communication node based on the first control information, or it can be understood as determining the SMTC adopted by the first communication node based on the first control information. In one example, the number of SMTCs determined based on the first control information can be one or more.

[0063] It should be noted that before the first communication node determines the SMTC based on the first control information, it needs to receive one or more sets of SMTC configuration information sent by the second communication node that can be used by the first communication node. This allows the first communication node to select one or more SMTCs from all available SMTCs for use / adoption based on the first control information, knowing the configuration information of all available SMTCs.

[0064] In the measurement method of this application embodiment, the first communication node can determine one or more SMTCs according to the first control information, so that each adjacent cell associated with the first communication node can use a different SMTC. This can effectively avoid signal interference problems that occur when adjacent cells use the same SMTC for measurement, thereby improving the measurement accuracy of the first communication node, enhancing communication performance, and reducing the power consumption of the first communication node.

[0065] In one embodiment, the first control information includes at least one of the following:

[0066] Location information of the first communication node;

[0067] The beam information of the first communication node;

[0068] The synchronization signal block SSB information of the first communication node;

[0069] Information about the cell where the first communication node is located;

[0070] First configuration information; wherein, the first configuration information is used to indicate the configuration information of SMTC.

[0071] In one example, the location information of the first communication node can be its current location. If the second communication node calculates the current location information of the first communication node, it can then feed back the first communication node's current location information. If the first communication node is moving, the current location information fed back by the second communication node can be the first communication node's previous location information, not its real-time location information.

[0072] In one example, the process by which the first communication node obtains its own location information may include:

[0073] The first communication node calculates its own location information;

[0074] The second communication node calculates the location information of the first communication node and feeds back the location information of the first communication node to the first communication node.

[0075] It should be noted that when the first communication node or the second communication node calculates the location information of the first communication node, the relevant parameters it uses can be relevant input information, which can be obtained from one or more first communication nodes and / or one or more second communication nodes.

[0076] In one example, the first communication node or the second communication node can be located using at least one of the following positioning techniques: Cell ID positioning, Time of Arrival (TOA) positioning, Time Difference of Arrival (TDOA) positioning, beamforming positioning, and millimeter-wave positioning. In one example, cell ID positioning is implemented by obtaining which cell the first communication node is in, thereby determining the area range of the first communication node, i.e., obtaining the location information of the first communication node. In one example, TOA positioning, TDOA positioning, and beamforming positioning are implemented by obtaining calculated parameters from multiple second communication nodes, and then calculating the location information of the first communication node based on these parameters.

[0077] In one example, the first communication node can determine the SMTC based on at least one of the following: the location information of the first communication node, the beam information of the first communication node, the SSB information of the first communication node, the cell information of the first communication node, and the first configuration information.

[0078] In one example, regarding the case where the SMTC is determined based on the location information of the first communication node:

[0079] If the current location information of the first communication node is within the central range of a cell, the SMTC associated with that cell and / or adjacent cells can be used as the SMTC determined by the first communication node.

[0080] If the current location information of the first communication node is at or near the boundary of two cells, then the SMTC associated with the two cells and / or adjacent cells is the SMTC determined by the first communication node.

[0081] If the current location information of the first communication node is at or near the boundary of three cells, then the SMTC associated with the three cells and / or adjacent cells is the SMTC determined by the first communication node.

[0082] If the current location information of the first communication node is at or near the boundary of multiple cells, then the SMTC associated with the multiple cells and / or adjacent cells is the SMTC determined by the first communication node.

[0083] In one example, regarding the case of determining the SMTC based on the beam information of the first communication node:

[0084] If a cell is covered by multiple beams, the SMTC associated with the cell covered by the beam and other cells adjacent to the coverage area of ​​the beam can be used / adopted by the first communication node.

[0085] For example, Figure 4 is a schematic diagram of an implementation of SMTC determination provided in an embodiment of this application. As shown in Figure 4, assuming nine cells are configured (cell 1, cell 2...cell 9), and cell 3 contains three beams (Beam1, Beam2, and Beam3), and the first communication node (e.g., node 1) is located within the coverage area of ​​Beam1, then the SMTC associated with the cells covered by Beam1 and the adjacent cells in the coverage area of ​​Beam1 can be the SMTC determined by node 1. That is, the SMTC associated with cells 1, 2, and 3 is the SMTC determined by node 1. It should be noted that this is only a specific embodiment provided for clarity. In actual operation, there are other possibilities. For example, the other cells adjacent to the beam may include other cases, such as cells 4 and 5 adjacent to beam 1, which will not be listed here. It should be noted that the cells covered by the beam described here may include cases where the beam covers only a part of the cell area.

[0086] In one example, regarding the case where the SMTC is determined based on the SSB information of the first communication node:

[0087] If a cell is covered by multiple beams carrying SSBs, the SMTC associated with the cell carrying the SSB and other adjacent cells in the coverage area of ​​the SSB can be used as the SMTC determined by the first communication node.

[0088] The situation is different for the SSB carried on the beam:

[0089] For example, as shown in Figure 4, suppose there are 9 cells configured (cell 1, cell 2...cell 9), and each cell contains 3 beams (Beam1, Beam2, and Beam3). If the SSBs carried on each beam are different (for example, SSB1, SSB2, and SSB3 carried by Beam1, Beam2, and Beam3 respectively), and the first communication node (e.g., node 1) is located within the coverage area of ​​SSB1, then the SMTC associated with the cell carrying SSB1 and its adjacent cells can be determined by node 1. That is, the SMTC associated with cells 1, 2, and 3 is determined by node 1. It should be noted that this is only a specific embodiment provided for clarity. In actual operation, other possibilities exist. For example, the other cells adjacent to the beam may include other cases, such as cells 4 and 5 adjacent to SSB1, which will not be listed here.

[0090] The same applies to the SSBs carried on the beam:

[0091] For example, as shown in Figure 4, assume there are 9 cells configured (cell 1, cell 2...cell 9), and each cell contains 3 beams (Beam1, Beam2, and Beam3). Furthermore, some beams carry the same SSB (e.g., Beam1 and Beam3 both carry SSB1). The first communication node (e.g., node 1) is located within the coverage area of ​​SSB1. In this case, the neighboring cells of SSB1 are cell 1, cell 2, cell 5, and cell 6. If the SMTCs associated with cell 1, cell 2, cell 5, cell 6, and cell 3 are SMTC1, SMTC2, SMTC3, SMTC1, and SMTC4 respectively, then SMTC1, SMTC2, SMTC3, and SMTC4 are the SMTCs used / adopted by node 1. It should be noted that this is only a specific embodiment provided for clarity. In actual operation, other possibilities exist, such as other cells adjacent to the beam, for example, SSB1 may also be adjacent to cells 4 and 7, which will not be listed here.

[0092] In one example, regarding the case where the SMTC is determined based on the cell information of the first communication node:

[0093] If the first communication node is in a cell, the first communication node can use the SMTC associated with its own cell and neighboring cells as the SMTC it uses / adopts.

[0094] If the first communication node is in multiple cells at the same time, the first communication node can use the SMTC associated with these multiple cells and adjacent cells as the SMTC to determine its own use / adoption.

[0095] In one example, the SMTC situation can be determined for the first communication node based on the first configuration information:

[0096] The second communication node can send the first configuration information to the first communication node. The first configuration information is used to indicate the configuration information of one or more SMTCs. Then the first communication node can directly use the one or more SMTCs as the SMTCs it uses / adopts, or it can use one or more SMTCs from the multiple SMTCs sent by the second communication node as the SMTCs it determines to use / adopt.

[0097] In one embodiment, the beam information includes at least one of the following: beam identifier; beam index; beam direction; beam type.

[0098] In one example, a beam identifier can be a unique number or name that identifies a beam, used to distinguish different beams; the beam identifier can be a Beam ID or a Beam Name. Each beam can be numbered according to a numbering rule to obtain a unique beam identifier for each beam.

[0099] In one example, a beam index is a location number of a beam within a specific list or set, which can be used to quickly locate and access the beam. A beam index can also be called a Beam Index. The numbering spaces corresponding to beam identifiers and beam indices are different; that is, a beam identifier can be unique across the entire network or unique within a specific cell or base station; while a beam index is generally unique within a specific list or set.

[0100] For example, suppose a cell is configured with 8 SSB beams and other types of beams. These 8 SSB beams can be formed into an SSB beam set. In the SSB beam set, these 8 SSB beams are numbered as: Beam0, Beam1, Beam2...Beam7. Then the beam indices of these 8 SSB beams in the SSB beam set are Beam0, Beam1, Beam2...Beam7.

[0101] In one example, beam direction refers to the direction in which each beam is transmitted or received, and can be expressed in angles (such as azimuth and elevation).

[0102] In one example, beam type refers to a classification based on beam purpose or beam characteristics. For instance, beam type can include, but is not limited to, at least one of the following: Broadcast Beam, Control Beam, Data Beam, and Sounding Reference Signal Beam (SRS Beam). In one example, the broadcast beam is used to transmit broadcast information and can also be used to carry or transmit synchronization signal blocks (SSBs) to enable the first communication node to complete initial access and synchronization. It can be understood that beam type also includes: SSB beam. An SSB beam can also be called a synchronization beam.

[0103] In one embodiment, the beam includes at least one beam from the same cell and / or at least one adjacent cell. In one example, a cell may contain one or more beams.

[0104] In cases where the beams include one or more beams in the same cell, they may include: one or more beams in the serving cell where the first communication node is located, or one or more beams in a cell adjacent to the serving cell where the first communication node is located.

[0105] For cases where the beam includes at least one beam from at least one adjacent cell, it may include: one or more beams from one or more adjacent cells of the serving cell where the first communication node is located.

[0106] In cases where the beams include one or more beams from the same cell and at least one adjacent cell, the beams may include: one or more beams from the serving cell where the first communication node is located, and one or more beams from one or more adjacent cells of the serving cell where the first communication node is located.

[0107] In one embodiment, the SSB information includes at least one of the following: an SSB identifier; an SSB index.

[0108] In one example, an SSB identifier can be a unique number or name that identifies an SSB, used to distinguish different SSBs; the SSB identifier can be an SSB ID or an SSB Name. Each SSB can be numbered according to a numbering rule to obtain a unique SSB identifier for each SSB.

[0109] For example, within a cell, multiple configured SSBs can be numbered in a specific order. In one example, an SSB index is the location number of an SSB within a specific list or set, which can be used for quick location and access to the SSB. An SSB index can be called an SSB Index. The numbering spaces corresponding to SSB identifiers and SSB indices are different; that is, an SSB identifier can be unique throughout the entire network or unique within a specific cell or base station; while an SSB index is generally unique within a specific list or set. Assuming a base station is configured with four beams for scanning to transmit different versions of the same SSB (covering the cell from different directions), these SSBs can be numbered as: SSB 0, SSB 1, SSB 2, and SSB 3, meaning their indices within this SSB set are SSB 0, SSB 1, SSB 2, and SSB 3, respectively.

[0110] In one embodiment, an SSB includes at least one SSB from the same cell and / or at least one adjacent cell. In one example, a cell may contain one or more beams, each beam carrying one SSB.

[0111] In cases where an SSB includes one or more SSBs within the same cell, it may include: one or more SSBs in the serving cell where the first communication node is located, or one or more SSBs in a cell adjacent to the serving cell where the first communication node is located.

[0112] In cases where an SSB includes at least one SSB from at least one neighboring cell, it may include: one or more SSBs from one or more neighboring cells of the serving cell where the first communication node is located.

[0113] In cases where an SSB includes one or more SSBs from the same cell and at least one adjacent cell, it may include: one or more SSBs from the serving cell where the first communication node is located, and one or more SSBs from one or more adjacent cells of the serving cell where the first communication node is located.

[0114] In one embodiment, the cell information includes at least one of the following: cell identifier; cell index; cell type.

[0115] In one example, a cell identifier can be a unique number or name that identifies a cell, used to distinguish different cells; the cell identifier can be a cell ID or a cell name. Each cell can be numbered according to a numbering rule to obtain a unique cell identifier for each cell. For example, within a base station, multiple configured cells can be numbered in a certain order.

[0116] In one example, a cell index is a cell's location number within a specific list or set, used for quick cell location and access. A cell index can also be called a cell index. The numbering spaces corresponding to cell identifiers and cell indexes are different; that is, a cell identifier can be unique across the entire network or unique within a specific base station, while a cell index is generally unique within a specific list or set.

[0117] In one example, cell types can be categorized according to cell function, coverage area, or application scenario. For instance, they can be categorized according to application scenario, and cell types can include at least one of the following: primary cell, secondary cell, NR cell, LTE cell, NTN cell, TN cell. Alternatively, they can be categorized according to coverage area, and cell types can include at least one of the following: macro cell, micro cell, pico cell.

[0118] In one embodiment, a cell includes a currently serving cell and / or at least one neighboring cell. The currently serving cell is the cell where the first communication node has currently established a connection and is using its resources for communication; the at least one neighboring cell is one or more cells adjacent to the first communication node's currently serving cell. In one example, the cell information of the first communication node may include: relevant information about the first communication node's currently serving cell, and relevant information about one or more cells adjacent to the first communication node's currently serving cell.

[0119] In one embodiment, the measurement method applied to the first communication node further includes: receiving first configuration information generated by the second communication node. In one example, the second communication node generates the first configuration information and sends the first configuration to the first communication node, so that the first communication node can determine the SMTC based on the first control information, given the first configuration information.

[0120] In one embodiment, the relevant configuration information of SMTC includes at least one of the following: period; offset; duration; physical cell identifier list; and SSB to be measured.

[0121] In one example, the period can be referred to as periodicity or other terms; the offset can be referred to as offset or other terms; the duration refers to the time window, measurement window, or measurement time window, which is used to characterize the duration for which the first communication node performs the measurement; the physical cell identifier list can be referred to as Pci-List or other terms, which is used to characterize which cells the SMTC parameters apply to; the SSB to be measured can be referred to as SSB-ToMeasure or other terms, and the SSB to be measured can include the type of SSB to be measured, the number of SSBs to be measured, or the kinds of SSBs to be measured, etc.; the SSB types of each cell may be different, and a cell can contain multiple SSBs. The SSB to be measured can be used to characterize which types of SSBs need to be measured.

[0122] For example, Figure 5 is a schematic diagram of the configuration of period, offset and duration provided in an embodiment of this application. As shown in Figure 5, if the offset is 0, the start time of the duration coincides with the start time of the period; if the offset is not 0, the start time of the duration does not coincide with the start time of the period.

[0123] In one embodiment, the measurement method applied to the first communication node further includes: performing measurements based on a determined SMTC.

[0124] In one example, the first communication node can measure the Reference Signal Received Power (RSRP) of the SSB using a defined SMTC to obtain the RSRP measurement result; it can also measure the Reference Signal Received Quality (RSRQ) of the SSB to obtain the RSRQ measurement result; or it can measure both the RSRP and RSRQ of the SSB to obtain the RSRP and RSRQ measurement results. In one example, if the measurement result reporting trigger condition is met, the first communication node can report the measurement result to the second communication node, so that the second communication node can evaluate the signal quality and strength based on the measurement result.

[0125] In one embodiment, measurement based on a defined SMTC includes listening to or measuring the corresponding SSB within the duration of the defined SMTC. In one example, the first communication node may measure one or more corresponding SSBs within the duration contained in each cycle of the defined SMTC, for example, it may measure or listen to the RSRP and / or RSRQ of one or more corresponding SSBs to obtain the corresponding measurement results.

[0126] In one embodiment, the corresponding SSB includes at least a portion of the SSBs of one or more cells associated with the determined SMTC. In one example, the determined SMTC may be one or more SMTCs, each SMTC associated with at least one cell, each cell may contain one or more beams, and each beam carries one SSB; if the determined SMTC is an SMTC associated with a current serving cell, the corresponding SSB may be a portion of the SSB of the current serving cell or all of the SSBs of the current serving cell; if the determined SMTC is an SMTC of one or more neighboring cells of the current serving cell, the corresponding SSB may be a portion of the SSB of each neighboring cell or all of the SSBs of each neighboring cell.

[0130] In one example, the cells that are active simultaneously under a satellite are clustered, which can be applied to scenarios where multiple first communication nodes are concentrated in a certain area; the cells that are active under a satellite are dispersed, which can be applied to scenarios where multiple first communication nodes are dispersed in several areas.

[0132] In one embodiment, at the same time, the activation state of the beams contained in each cell includes one of the following: all beams are activated simultaneously; all beams are deactivated simultaneously; some beams are activated; and some beams are deactivated.

[0133] In one example, "all beams" refers to all beams of all beam types contained within a cell; "partial beams" refers to all beams of some beam types contained within a cell, or some beams of all beam types. For example, if a cell contains SSB beams, control beams, and data beams, then all beams of the three beam types within the cell can be activated simultaneously, or all beams of the three beam types within the cell can be deactivated simultaneously; or, all SSB beams within the cell can be activated simultaneously, and all control beams and all data beams can be deactivated simultaneously; or, some SSB beams and some control beams within the cell can be activated simultaneously, and some SSB beams, beam control beams, and all data beams can be deactivated simultaneously.

[0134] In one embodiment, at the same time, the activation state of the beams contained in each cell includes one of the following: all SSB beams are activated simultaneously; all SSB beams are deactivated simultaneously; some SSB beams are activated; and some SSB beams are deactivated.

[0135] In one example, "all SSB beams" refers to all beams of type SSB contained within a cell; "partial beams" refers to a portion of the beams of type SSB contained within a cell.

[0157] In one embodiment, FIG6 is a flowchart of another measurement method provided by an embodiment of this application. This embodiment is applied to the case of determining the SMTC used by the first communication node. This embodiment can be executed by the second communication node. As shown in FIG6, this embodiment includes: S210.

[0158] S210. Send the first control information to the first communication node so that the first communication node determines the SMTC based on the first control information; wherein, the first control information is used to indicate the relevant information on which the SMTC determination is based.

[0159] In one embodiment, the first control information includes at least one of the following:

[0160] Location information of the first communication node;

[0161] The beam information of the first communication node;

[0174] In one embodiment, the measurement method applied to the second communication node further includes: receiving a measurement result reported by the first communication node; wherein the measurement result is obtained by the first communication node based on a determined SMTC.

[0175] In this embodiment, after determining the SMTC of each cell, the first communication node can use the measurement results of the corresponding cell obtained from the SMTC configuration information, such as the signal quality and signal strength of the corresponding cell. For example, assuming the first communication node determines that the SMTCs corresponding to cells 1, 2, and 3 are SMTC1, SMTC2, and SMTC3 respectively, and uses SMTC1, SMTC2, and SMTC3 to measure the signal quality and signal strength of cells 1, 2, and 3 respectively, and finds that the signal strength and signal quality of cell 3 (the current serving cell) are very poor, the first communication node can trigger a measurement reporting process and report the measurement results of each cell (including the good signal strength and signal quality of cell 1 (the neighboring cell)) to the second communication node. The second communication node analyzes the measurement results, selects cell 1 as the target cell for the first communication node, and then sends a cell handover command to the first communication node to switch to cell 1, thus completing the access process. It should be noted that this is only an exemplary description; in actual operation, other operational procedures can be used, and this application does not limit this operational procedure.

[0191] In the following embodiments, taking the first communication node as the UE and the second communication node as the base station as an example, the selection of SMTC and the process of using SMTC for measurement will be explained.

[0192] For the UE side:

[0193] When a UE selects an SMTC, it can do so based on at least one of the following: the UE's location information (also known as positioning information), the SSB beam, the SSB information, and the cell information it is in; and then perform measurements based on the selected SMTC.

[0194] In one example, measurement based on the selected SMTC involves listening to or measuring the corresponding SSB during the duration of the selected SMTC.

[0195] In one example, if SMTC selection is performed based on the UE's location information, the UE needs to obtain its own location information, which can be obtained from the UE itself and / or the base station.

[0196] In one example, if SMTC selection is performed based on the SSB beam in which the UE is located, the UE needs to obtain information about the SSB beam in which it is located.

[0200] In one example, a satellite can contain one or more cells.

[0207] In one example, in an NR NTN cell, SSB beam transmission in different spatial directions is possible, just as in an NR TN cell: the entire cell can be covered by different SSB beams in half a frame.

[0208] In one example, if a cell is defined by multiple satellite beams, then these satellite beams are either active or inactive simultaneously. In other words, beam hopping applies equally to all satellite beams of a given cell.
