[0002] Although 5G has started global commercial use, due to geographical conditions and business model limitations, it cannot guarantee network coverage in the open ocean and remote land areas. To break through terrain limitations, integrating satellite communication with terrestrial networks to form a seamless global coverage three-dimensional network of land, sea, air, and space has become a research hotspot in the current academic and industrial communities. Currently, Non-terrestrial networks (NTN) are committed to integrating satellite communication with 5G to solve the key problems of the New Radio (NR) supporting NTN. And the future integrated network of land, sea, air, and space mainly focuses on deep integration, combining multiple communication platforms to provide broader and more diverse communication services.

[0003] In the existing 5G network, to reduce overhead and interference from reference signals of other cells, the cell-specific reference signal (CRS) is removed in 5G (NR), and the synchronization signal (SS) / physical broadcast channel (PBCH) block (synchronization signal block, SSB) is introduced for cell signal measurement. This synchronization block consists of SS and PBCH, and its transmission period is longer than that of CRS. There is a signal interference problem during the measurement process.

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. Additionally, it should be noted that for the sake of description, only parts related to the present application rather than all structures are shown in the accompanying drawings.

[0030] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts depict the steps as sequential processes, many of the steps can be implemented in parallel, concurrently, or simultaneously. In addition, the order of the steps can be rearranged. The process can be terminated when its operations are completed, but it can also have additional steps not included in the drawings. The process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0031] It should be noted that the concepts such as "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] In addition, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other.

[0033] The downlink coverage of NTN is limited by satellite payload constraints. Due to power limitations and limited link bandwidth, it may not be possible to activate all the beams of this satellite simultaneously. In such a scenario, how to avoid interference between beams / cells in different cells is an urgent problem to be solved.

[0034] If the same SMTC is adopted by two adjacent cells, and the first communication node is located at the boundary of the two adjacent cells, during the measurement process, there will be an interference problem of receiving reference signals from the two adjacent cells.

[0035] In mobile communication, a terminal (User Equipment, UE) in the connected state will not only continuously measure the serving cell, but also measure adjacent cells according to network configuration in case the signal of the serving cell deteriorates or for cell handover due to other reasons.

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

[0037] In the 5G (NR) network, to reduce overhead and interference from reference signals of other cells, CRS is removed in 5G (NR) and SS / PBCH blocks (SSB) are introduced for cell signal measurement. The synchronization block consists of a synchronization signal (SS) and a physical broadcast channel (PBCH), and its transmission period is longer than that of 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) among 5, 10, 20, 40, 80 or 160 ms; and the UE does not need to measure the cell signal periodically like SSB, and can configure a suitable measurement period according to the channel conditions to help avoid unnecessary measurements and reduce the power consumption of the UE.

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

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

[0041] From the comparison between Fig. 1(b) and Fig. 2(b), different SMTC periods and different SMTC durations can be used for SSB measurement. When the base station notifies the measurement window of SMTC to the UE, the UE can detect and measure the SSBs within the measurement window and report the measurement results to the base station.

[0042] In view of this, the present application provides a measurement method. The first communication node can determine one or more SMTCs according to the first control information, so as to avoid the situation that even when the first communication node is at the boundary of two adjacent cells, the SMTCs adopted by the two adjacent cells are still different, thereby being able to avoid signal interference between different cells. At the same time, it can also reduce the power consumption of the first communication node, and thus extend the standby time of the first communication node.

[0043] The first communication node in the embodiments of the present application can be a user equipment (UE), and the second communication node can be a network device.

[0044] The UE in the embodiments of the present application, which can be referred to as a terminal, can be a mobile terminal or a vehicle-mounted terminal, etc. Among them, the UE includes all devices that provide voice and / or data connectivity to users. For example, 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 user equipment (REDCAP UEs), subscriber units, subscriber stations, mobile stations, remote stations, access points (APs), remote terminals, access terminals, user terminals, user agents, or user equipment, etc. It can also be a user equipment in a future communication system, and this patent does not limit this.

[0045] The network device in the embodiments of the present application may be an access network device, a core network device, a server, etc. The access network device may be a base station in a terrestrial communication network or a base station in an NTN network. For example, an evolved Node B (eNB), a next-generation Node B (gNB) in an NR system, a Road Side Unit (RSU), or a Centralized Unit (CU) and a Distributed Unit (DU) in a cloud access network system. It may also be an access network device in a future communication system. The base station in the NTN network may include: a transparent transmission type base station, a regenerate type base station, and other types of base stations. The base station may be mounted on a non-terrestrial or aerial device. For example, it may be located on a satellite, a space station, or other aircraft. The core network device may be a Mobility Management Entity (MME), a Serving Gateway (SGW), a Packet Data Node Gateway (PGW), a Home Subscriber Server (HSS) that stores user subscription information, a Policy and Charging Rule Function (PCRF), etc. It may also be a core network device in a future communication system, and the present application does not limit this.

[0046] The present application provides an example of a measurement method applied to a first communication node. The method includes:

[0047] Determine the SMTC, where the SMTC is the measurement time configuration of the SS / PBCH.

[0048] In one example, for the first communication node to determine the SMTC, it may include at least one of the following:

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

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

[0051] In one example, for the first communication node to select one or more SMTCs, it may include at least one of the following:

[0052] Autonomously select one or more SMTCs;

[0053] Randomly select one or more SMTCs;

[0054] Select one or more SMTCs according to the first control information.

[0055] In one example, the case where 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 based on the analysis result, autonomously select one or more SMTCs.

[0056] In one example, the case where 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 pre-received SMTCs. Among them, the one or more pre-received SMTCs can be one or more SMTCs sent by the second communication node. Further, when the second communication node sends one or more SMTCs, it can be understood that the second communication node sends an SMTC set, and this SMTC set can be a set of all SMTCs pre-generated by the second communication node and sent to the first communication node for the first communication node to use.

[0057] In one example, the case where the first communication node selects one or more SMTCs according to the first control information: The first communication node can select one or more SMTCs according to one or more pieces of information in the first control information for the first communication node to use. Among them, the first communication node can select one or more SMTCs according to at least one of the location information of the first communication node, the beam information where the first communication node is located, the synchronization signal block SSB information of the first communication node, the cell information where the first communication node is located, the first configuration information, or other information.

[0058] In one example, the case where the first communication node adopts a specified one or more SMTCs: The second communication node can provide an indication information for indicating the identification, 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 adopts the one or more SMTCs indicated by this indication information. Further, the first communication node can adopt all or part of the SMTCs indicated by this indication information.

[0059] In this application, taking the determination of one or more SMTCs according to one or more pieces of information in the first control information as an example, the determination process of SMTC is described.

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

[0061] S110. Determine the SMTC according to the first control information; where the first control information is used to indicate the relevant information based on which the SMTC is determined.

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

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

[0064] In the measurement method of the embodiment of the present application, 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 adopt different SMTCs, thereby effectively avoiding the signal interference problem that occurs during the process of adjacent cells adopting the same SMTC for measurement, thereby improving the measurement accuracy of the first communication node, enhancing the 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] The location information of the first communication node;

[0067] The beam information where the first communication node is located;

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

[0069] The cell information where the first communication node is located;

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

[0071] In one example, the location information of the first communication node can be the current location information of the first communication node. In the case where the second communication node calculates the current location information of the first communication node, the second communication node can feedback the current location information of the first communication node to the first communication node. If the first communication node is in the process of moving, the current location information feedback by the second communication node can be the previous location information of the first communication node, rather than the real-time location information of the first communication node.

[0072] In one example, the implementation process for the first communication node to obtain its own location information can 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 can be relevant input information, and the relevant input information 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 use at least one of the following positioning technologies to locate the first communication node: Cell ID positioning, Time of Arrival (TOA) positioning, Time Difference of Arrival (TDOA) positioning, beamforming positioning, and millimeter wave positioning, etc. In one example, the implementation method of Cell ID positioning includes: obtaining which cell the first communication node is in to determine the area range where the first communication node is located, that is, obtaining the location information of the first communication node. In one example, the implementation methods of TOA positioning, TDOA positioning, and beamforming positioning: parameters calculated can be obtained through multiple second communication nodes, and the location information of the first communication node can be calculated based on these parameters.

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

[0078] In one example, for the case of determining the SMTC according to the location information of the first communication node:

[0079] If the current location information of the first communication node is within the center range of a cell, the SMTC associated with this cell and / or adjacent cells can be determined as the SMTC for the first communication node;

[0080] If the current location information of the first communication node is at or near the boundary of two cells, the SMTCs associated with these two cells and / or adjacent cells respectively can be determined as the SMTC for the first communication node;

[0081] If the current location information of the first communication node is at or near the boundary of three cells, the SMTCs associated with these three cells and / or adjacent cells respectively can be determined as the SMTC for the first communication node.

[0082] If the current location information of the first communication node is at or near the boundaries of multiple cells, the SMTCs associated with the multiple cells and / or neighboring cells respectively are the SMTCs determined for the first communication node.

[0083] In one example, for the case of determining the SMTC according to the beam information of the first communication node:

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

[0085] Exemplarily, Figure 4 is a schematic diagram for realizing the determination of an SMTC provided by an embodiment of the present application. As Figure 4 shown, assume that 9 cells are configured (cell 1, cell 2... cell 9 respectively), and cell 3 includes 3 beams (Beam1, Beam2, and Beam3). The first communication node (for example, node 1) is located within the coverage range of Beam1. At this time, the SMTCs associated with the cell covered by Beam1 and the cells adjacent to the coverage area of Beam1 can be used as the SMTCs determined for node 1, that is, the SMTCs associated with cell 1, cell 2, and cell 3 are the SMTCs determined for node 1. It should be noted that only a specific embodiment is provided here for clear description. In actual operation, there are other possibilities. For example, other cells adjacent to the beam also include other situations. For example, other cells adjacent to beam Beam1 also include cell 4 and cell 5, which are not listed here. It should be noted that the cell covered by the beam described here may include the situation where the beam covers a part of the cell.

[0086] In one example, for the case of determining the SMTC according to the SSB information of the first communication node:

[0087] If a cell is covered by multiple beams carrying SSBs, the SMTCs associated with the cell where the beam carrying the SSB is located and other cells adjacent to the coverage area of the beam carrying the SSB can be used as the SMTCs determined for the first communication node.

[0088] Among them, for the case where the SSBs carried on the beams are different:

[0089] Exemplarily, as Figure 4As shown, assume that 9 cells are configured (cell 1, cell 2... cell 9 respectively), and each cell contains 3 beams (Beam1, Beam2, and Beam3). At this time, if the SSBs carried on each beam are different (for example, the SSBs carried on Beam1, Beam2, and Beam3 are SSB1, SSB2, and SSB3 respectively), and the first communication node (for example, node 1) is within the coverage of SSB1, then the cell where the beam carrying SSB1 is located and the SMTC determined by the SMTC associated with the adjacent cells for node 1 can be used. That is, the SMTC determined by the SMTC associated with cell 1, cell 2, and cell 3 for node 1. It should be noted that this is only a specific example provided for clarity of expression. In actual operation, there are other possibilities. For example, there are other situations for the other cells adjacent to this beam. For example, the other cells adjacent to SSB1 also include cell 4 and cell 5, which are not listed here.

[0090] Among them, for the case where the SSBs carried on the beams are the same:

[0091] Exemplarily, as Figure 4 shown, assume that 9 cells are configured (cell 1, cell 2... cell 9 respectively), and each cell contains 3 beams (Beam1, Beam2, and Beam3). And, the SSBs carried on some beams are the same (for example, the SSBs carried on Beam1 and Beam3 are both SSB1). The first communication node (for example, node 1) is within the coverage of SSB1. At this time, the adjacent 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 determined and used / adopted by node 1. It should be noted that this is only a specific example provided for clarity of expression. In actual operation, there are other possibilities. For example, there are other situations for the other cells adjacent to this beam. For example, the other cells adjacent to SSB1 also include cell 4 and cell 7, which are not listed here.

[0092] In one example, for the case of determining the SMTC according to 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 the adjacent cells as the SMTC it uses / adopts.

[0094] If the first communication node is simultaneously in multiple cells, the first communication node may associate the multiple cells and the SMTC associated with the neighboring cells as the SMTC determined for its own use / adoption.

[0095] In an example, for the case where the first communication node can determine the SMTC based on the first configuration information:

[0096] The second communication node may send the first configuration information to the first communication node, and the first configuration information is used to indicate the configuration information of one or more SMTCs; then the first communication node may directly use one or more of the one or more SMTCs as the SMTC for its own use / adoption, or may use one or more of the multiple SMTCs sent by the second communication node as the SMTC determined for its own use / adoption.

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

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

[0099] In an example, the beam index is the position number of a beam in a specific list or set and can be used for quick positioning and access to the beam. The beam index may be referred to as Beam Index. The numbering spaces corresponding to the beam identifier and the beam index are different, that is, the beam identifier may be unique in the entire network or may be unique in a certain cell or base station; while the beam index is generally unique in a certain list or set.

[0100] Exemplarily, assume that a cell is configured with 8 SSB beams and other types of beams. These 8 SSB beams can form an SSB beam set, and these 8 SSB beams are numbered as Beam0, Beam1, Beam2... Beam7 in the SSB beam set respectively. Then the beam indices of these 8 SSB beams in the SSB beam set are Beam0, Beam1, Beam2... Beam7.

[0101] In an example, the beam direction refers to the transmission direction or reception direction of each beam and can be represented by an angle (for example, azimuth angle, elevation angle).

[0102] In one example, beam types are classified according to beam usage or beam characteristics. For example, beam types may include, but are 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 send broadcast information and can also be used to carry or transmit Synchronization Signal Block (SSB) to enable the first communication node to complete initial access and synchronization. It can be understood that the beam types also include: SSB beam. The SSB beam can also be referred to as a synchronization beam.

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

[0104] For the case where the beam includes one or more beams in the same cell, it may include: one or more beams in the serving cell where the first communication node is located, or one or more beams in an adjacent cell to the serving cell where the first communication node is located.

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

[0106] For the case where the beam includes one or more beams in the same cell and at least one adjacent cell, it may include: one or more beams in the serving cell where the first communication node is located, and one or more beams in one or more adjacent cells to the serving cell where the first communication node is located.

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

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

[0109] Exemplarily, in a cell, multiple configured SSBs can be numbered in a certain order. In one example, the SSB index is the position number of an SSB in a specific list or set, which can be used to quickly locate and access the SSB. The SSB index can be referred to as the SSB Index. The numbering spaces corresponding to the SSB identification and the SSB index are different, that is, the SSB identification can be unique in the entire network or unique in a certain cell or base station; while the SSB index is generally unique in a certain list or set. Assuming that the base station configures 4 beams for scanning to send different versions of the same SSB (covering the cell from different directions), then these SSBs can be numbered as SSB 0, SSB 1, SSB 2, and SSB 3 respectively, that is, the indexes of these SSBs in this SSB set are SSB 0, SSB 1, SSB 2, and SSB 3 respectively.

[0110] In one embodiment, the SSB includes at least one SSB in the same cell and / or at least one adjacent cell. In one example, in a cell, there can be one or more beams, and each beam carries an SSB.

[0111] For the case where the SSB includes one or more SSBs in the same cell, it can include: one or more SSBs in the serving cell of the first communication node, or one or more SSBs in a cell adjacent to the serving cell of the first communication node.

[0112] For the case where the SSB includes at least one SSB in at least one adjacent cell, it can include: one or more SSBs in one or more adjacent cells of the serving cell of the first communication node.

[0113] For the case where the SSB includes one or more SSBs in the same cell and at least one adjacent cell, it can include: one or more SSBs in the serving cell of the first communication node, and one or more SSBs in one or more adjacent cells of the serving cell of the first communication node.

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

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

[0116] In one example, the cell index is the position number of a cell in a specific list or set, which can be used to quickly locate and access the cell. The cell index can be referred to as the cell Index. The number spaces corresponding to the cell identifier and the cell index are different, that is, the cell identifier can be unique throughout the network or unique within a certain base station; while the cell index is generally unique within a certain list or set.

For another example, it can be divided according to the coverage area, and the cell type can include at least one of the following: macro cell, micro cell, pico cell.

[0118] In one embodiment, the cell includes the current serving cell and / or at least one adjacent cell. The current serving cell is the cell to which the first communication node currently establishes a connection and uses its resources for communication; the at least one adjacent cell is one or more cells adjacent to the current serving cell of the first communication node. In one example, the cell information where the first communication node is located can include: the relevant information of the current serving cell of the first communication node, and the relevant information of one or more cells adjacent to the current serving cell of the first communication node.

[0119] In one embodiment, the measurement method applied to the first communication node further includes: receiving the 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 according to the first control information when knowing the first configuration information.

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

[0122] Exemplarily, Figure 5 is a schematic diagram of the configuration of a period, an offset, and a duration provided by an embodiment of the present application. As Figure 5 shown, when the offset is 0, the start time of the duration coincides with the start time of the period; when 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 the determined SMTC.

In one example, when 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, performing measurements based on the determined SMTC includes: listening to or measuring the corresponding SSB within the duration of the determined SMTC. In one example, the first communication node can measure one or more corresponding SSBs within the duration included in each period of the determined SMTC.

[0133] In one example, all beams refer to all the beams of all beam types included in a cell; partial beams refer to all the beams of some beam types included in a cell, or some beams of all beam types. Exemplarily, if a cell includes SSB beams, control beams, and data beams, then all the beams of the three beam types in this cell are activated at the same time, or all the beams of the three beam types in this cell are not activated at the same time; or all the SSB beams in this cell are activated at the same time, and all the control beams and all the data beams are not activated at the same time; or some of the SSB beams and some of the control beams in this cell are activated at the same time, and some of the SSB beams, some of the beam control beams, and all the data beams are not activated at the same time.

Send the first control information to the first communication node so that the first communication node determines the SMTC according to the first control information; wherein, the first control information is used to indicate the relevant information based on which the SMTC is determined.
