[0001] Related applications
[0002] This application claims priority to Chinese invention patent filed on January 26, 2025, application number 202510125461.X, entitled "A Communication Measurement Configuration Method, Device and Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field
[0003] This specification relates to the field of communication technology, and in particular to a communication measurement configuration method, device and storage medium. Background Technology
[0004] In 5G mobile communication systems, to ensure service continuity for terminals during mobility, terminals need to measure the signal strength of neighboring cell beams while simultaneously detecting the signal strength of the serving cell. The target of this measurement is the reference signal SSB (SS / PBCH Block, synchronization signal and physical layer broadcast channel block). The SSB is carried on a specific beam after beamforming, and a cell can have multiple SSBs. Multiple temporally adjacent SSBs form an SSB burst set, and each SSB in the burst set corresponds to a unique index. SSBs with different indices have fixed temporal positions and are transmitted sequentially through beam scanning to achieve full-cell coverage of the synchronization signal.
[0005] 3GPP mandates that the effective scope of system information be at least at the cell level, meaning that the content of system information broadcast within a cell must be identical. When downlink coverage enhancement is achieved by extending the SSB period, in most measurement windows, the terminal listens for neighboring cell SSBs that are completely undetectable by the receiver, severely impacting the terminal's standby power consumption. Summary of the Invention
[0006] The purpose of the embodiments in this specification is to provide a communication measurement configuration method, device and storage medium to solve the problem of high power consumption in terminal measurement in the prior art.
[0007] To achieve the above objectives, in one aspect, embodiments of this specification provide a communication measurement configuration method, which is applied to the base station side, and the method includes:
[0008] Configuring corresponding measurement configuration information for beams specific to the transmission of synchronization signals and physical layer broadcast channel blocks (SSBs);
[0009] The configured measurement configuration information is broadcast to the coverage area corresponding to the beam of the transmitting SSB.
[0010] On the other hand, embodiments of this specification also provide a communication measurement configuration method, which is applied to the terminal side, and the method includes:
[0011] Identify whether the beam of the transmission SSB selected by the terminal has changed;
[0012] If the beam of the transmission SSB selected by the terminal changes, the system receives system information and obtains measurement configuration information specific to the transmission SSB selected by the terminal.
[0013] On the other hand, embodiments of this specification also provide a base station, including:
[0014] At least one processor; and
[0015] At least one memory storing instructions that, when executed individually or jointly by the at least one processor, cause the base station to perform the aforementioned base station-side communication measurement configuration method.
[0016] On the other hand, embodiments of this specification also provide a terminal, including:
[0017] At least one processor; and
[0018] At least one memory storing instructions that, when executed individually or jointly by the at least one processor, cause the terminal to perform the aforementioned terminal-side communication measurement configuration method.
[0019] On the other hand, embodiments of this specification also provide a computer storage medium storing a computer program thereon, which, when run by the processor of a computer device, executes instructions for the above-described method.
[0020] On the other hand, embodiments of this specification also provide a computer program product, which includes a computer program that, when run by the processor of a computer device, executes instructions for the above-described method.
[0021] As can be seen from the technical solutions provided in the embodiments of this specification above, by broadcasting measurement configuration information specific to the beam of the SSB corresponding to each wave position (the coverage area of the beam transmitting the SSB), the embodiments of this specification can divide the cell into wave position granularity. The coverage area corresponding to the beam of the SSB corresponds to one wave position. Different measurement configuration information is configured for different beams of the SSB, so that the terminal (e.g., satellite terminal) located in the corresponding wave position can perform measurements only according to the measurement configuration information for that wave position, thereby reducing the power consumption of the terminal.

[0042] (1) Terminal Device: refers to a device that has wireless transceiver capabilities and can cooperate with network-side devices to provide communication services to users.

[0044] (2) Network equipment: refers to network-side equipment capable of communicating with terminal equipment. Network equipment can be located on satellites or the ground. Network equipment can also be called space base station, satellite-borne base station, satellite, satellite communication node, satellite network terminal equipment, satellite communication module, or base station, etc. This network-side equipment can also be called access network equipment or wireless access network equipment.

[0045] Both terminal devices and base station devices can perform beamforming, but the embodiments of this application are not limited to this. In some embodiments, the terminal may or may not perform beamforming. Furthermore, the base station may or may not perform beamforming. That is, only one of the terminal and the base station can perform beamforming, or neither the terminal nor the base station may perform beamforming. In this application, a beam refers to the spatial flow of signals in a wireless channel, formed by one or more antennas or antenna elements; such a formation process can be called beamforming.
[0046] Furthermore, the term "network side" or "network equipment side" refers to one side of the network, which can be a base station or include one or more network devices as described above. The term "terminal side" or "terminal equipment side" refers to the side of the user or terminal, which can be a UE or include one or more terminal devices as described above.
[0047] Due to the limited number of satellites and satellite antennas, a typical solution to achieve wide-area coverage is to extend the SSB default period (SSB-periodicityServingCell), allowing a single antenna to cover more ground areas in a time-division manner. 3GPP conducted a dedicated study on this in its downlink coverage enhancement project in release 19.
[0048] In terrestrial 5G communication scenarios, the SSB period is relatively short. Taking SSB pattern case C as an example, the SSB period is 20ms, and the 8 SSBs (SSB index 0 to 7) are concentrated in the first 2ms of each 20ms dual frame. Each cell can provide synchronization signals and access services for 8 wavelengths within 20ms.
[0049] In satellite communication downlink coverage enhancement scenarios, it is necessary to increase the SSB period. Taking an SSB period of 160ms as an example, from the perspective of a single terminal, an SSB will occur once every 160ms. From the perspective of the base station, it still sends 8 SSBs every 20ms, but within a 160ms period, the 64 SSBs sent by the base station are used to serve 64 different wavelengths (compared to only serving 8 wavelengths with a 20ms SSB period). In this way, the base station can serve more wavelengths and achieve downlink coverage enhancement by extending the SSB period of a single terminal.
[0050] The method of increasing the SSB period and expanding the number of service spectral bits within the period can effectively increase the satellite coverage area, but it will have a serious negative impact on the configuration of the measurement window. Taking the aforementioned scenario as an example, a beam transmitting a single SSB can cover 64 spectral bits with an SSB period of 160ms. When the terminal needs to measure neighboring cells, the possible time-domain locations of neighboring cell SSBs increase from 8 (these 8 SSBs are concentrated in the first 2ms of every 20ms, i.e., concentrated in one SSB burst set) to 64, and are scattered across 8 SSB burst sets (or SSB measurement time windows). It is impossible to explicitly indicate to the terminal the time-domain location that needs to be measured. This forces the terminal to perform blind detection within 8 measurement time windows where SSBs may exist (SMTC configuration granularity is 1ms, and the common configuration is one measurement time window per SSB burst set). However, in most scenarios, only one window may contain an SSB. This wastes terminal power consumption; furthermore, because most SSBs do not exist within the configured window, it also increases the false detection and false negative rates of SSBs by the terminal.
[0051] Figure 1 illustrates a neighbor detection window in a downlink coverage enhancement scenario. The figure depicts multiple distinct coverage areas (hereinafter referred to as "wave positions") corresponding to the beams of the transmitting SSB within a cell. Each hexagon in the figure represents a coverage area (wave position) corresponding to a beam of the transmitting SSB. In other embodiments, the shape of the wave position can be different and is not limited here. The beams of the transmitting SSB corresponding to different wave positions have different time-domain positions. Each wave position in the cell corresponds to a different SSB index. The time-domain position of the SSB beam indicates the measurement time window and includes multiple parameters used for measurement, such as parameters related to the SSB time-domain position, including SMTC, ssb-ToMeasure (for configuring the SSB mode), and ss-RSSI-Measurement (for configuring the received signal strength indication based on the synchronization reference signal). In this diagram, the data can be divided into the serving cell (the current cell) and neighboring cells (i.e., cells surrounding the serving cell). Neighboring cells include adjacent wavelengths (SSBs) adjacent to the serving cell, as well as wavelengths not adjacent to the serving cell. In existing technologies, the aforementioned measurement parameters are carried in System Information Blocks (SIBs), which are cell-specific. This means that only measurement windows for all wavelengths of the six neighboring cells surrounding the serving cell can be configured for the terminal. This results in only about one-quarter of the measurement windows being effective when the terminal measures neighboring cells; in most measurement windows, the terminal will futilely turn on the receiver to listen for undetectable SSBs of neighboring cells, severely impacting the terminal's standby power consumption. The embodiments in this specification represent a simple scenario with a single cell covering seven wavelengths. In real-world scenarios, a single cell can cover more wavelengths, and the more wavelengths, especially those at the edges, the more severe the aforementioned problem becomes. In the embodiments of this specification, in Figure 1, terminal a is located in the coverage area A (wavelength A) corresponding to the beam transmitting SSB. The adjacent cells are neighboring cell 2 and neighboring cell 3. The adjacent wavelengths in the neighboring cells are neighboring wavelength 1, neighboring wavelength 2, and neighboring wavelength 3. When performing neighboring cell measurements, terminal a only needs to measure the SSB of the beams corresponding to all wavelengths in the two neighboring cells (neighboring cell 2 and neighboring cell 3), or only needs to measure the SSB of the beams corresponding to the three adjacent wavelengths in the two neighboring cells. Similarly, terminal b only needs to measure the SSB of the beams corresponding to all wavelengths in the two neighboring cells (neighboring cell 5 and neighboring cell 6), or only needs to measure the SSB of the beams corresponding to the three adjacent wavelengths (neighboring wavelength 7, neighboring wavelength 8, and neighboring wavelength 9) in the two neighboring cells. That is to say, for different beams transmitting SSB, the corresponding measurement configuration information is configured specifically, which can greatly reduce the measurement work of the terminal and save terminal energy consumption.
[0052] Figure 2 shows a flowchart of a communication measurement configuration method according to an embodiment of this specification. This figure describes a measurement configuration method on the base station side. In a satellite communication system, the method described in this embodiment can be executed at the onboard base station, specifically including:
[0053] Step 201: Configure the corresponding measurement configuration information for the beam that transmits the SSB.
[0054] Step 202: Broadcast the configured measurement configuration information to the coverage area corresponding to the beam of the transmitting SSB.
[0055] The embodiments in this specification divide the cell into wavelength-level units by broadcasting measurement configuration information specific to the beam of the SSB corresponding to each wavelength position (the coverage area of the beam transmitting the SSB). One coverage area corresponding to one SSB beam corresponds to one wavelength position. Different measurement configuration information is configured for different SSB beams, so that terminals (e.g., satellite terminals) located in the corresponding wavelength position can perform measurements only according to the measurement configuration information for that wavelength position, thereby reducing the power consumption of the terminal.
[0056] In some embodiments, the measurement configuration information includes the time-domain location of the SSB of a cell adjacent to the coverage area corresponding to the beam of the transmitted SSB; and the time-domain location of the SSB of the serving cell to which the coverage area corresponding to the beam of the transmitted SSB belongs.
[0057] In this embodiment, the measurement configuration information corresponding to the coverage area (wave position) of each transmitted SSB beam can be broadcast to the wave position through SIB2 (System Information Block 2) or SIB4 (System Information Block 4), or it can be broadcast in the wave position through other means.
[0058] Furthermore, measurement configuration information for cell measurement by the terminal can be carried through SMTC, ssb-ToMeasure, ss-RSSI-Measurement, etc. in SIB2 and SIB4.
[0059] The measurement configuration information may include the time-domain location of all SSBs corresponding to the wavelet in the cells adjacent to the wavelet, and the time-domain location of all SSBs corresponding to the wavelet in the serving cell to which the wavelet belongs; it may also include the time-domain location of SSBs corresponding to adjacent wavelets in the cells adjacent to the wavelet, and the time-domain location of SSBs corresponding to adjacent wavelets in the serving cell to which the wavelet belongs.
[0060] As an example, Figure 3a illustrates an embodiment of adjacent area detection according to this specification. In this figure, the temporal positions of the SSBs corresponding to neighboring cells 1, 2, and 3 of the serving cell adjacent to cell A can be configured in the measurement configuration information corresponding to cell A, for use by terminal a in cell A. In this embodiment, the temporal positions of the SSBs corresponding to neighboring cells 4, 5, and 6 of the serving cell adjacent to cell A are configured in the measurement configuration information corresponding to cell A, so that terminal a in cell A can measure the temporal positions of the SSBs corresponding to neighboring cells 2 and 3, as well as the temporal position of the SSB of the serving cell.
[0061] Referring to Figure 3a, for wave position A, the neighbor cell measurement window broadcast by the base station to wave position A only includes the "wave position-level measurement configuration" of wave position A, that is, the time-domain position of the SSB of the beams corresponding to the neighboring wave positions 1, 2, 3, 4, 5, and 6 adjacent to wave position A. Among them, neighboring wave positions 1 and 2 belong to the same neighboring cell 2, and neighboring wave position 3 belongs to another neighboring cell 3. The neighboring cell 2 (neighboring cell 2) and the neighboring cell 3 (neighboring cell 3) are both adjacent to wave position A or have overlapping coverage. The time-domain position of the SSB of different wave positions can be represented by the SSB index. The time-domain positions of the SSBs corresponding to neighboring wave positions 1 and 2 of neighboring cell 2 are SSB index 3 and SSB index 4, respectively. The time-domain position of the SSB corresponding to neighboring wave position 3 of neighboring cell 3 is SSB index 4. Referring to Figure 3b, which is a schematic diagram of the measurement window configuration for wavelet A in this embodiment of the specification, and combining Figures 3a and 3b, the SSB indices corresponding to neighboring wavelet 1, neighboring wavelet 2, and neighboring wavelet 3 are SSB index 3, SSB index 4, and SSB index 4, respectively. Measurements only need to be performed in two measurement windows, SFN4 (System Frame Number) and SFN6, that is, the two measurement windows in the dashed box in Figure 3b. The corresponding SSB index range is from SSB index 0 to SSB index 7 for each cell. The terminal can clearly determine that in all 8 measurement windows within a 160ms period, only 2 of them need to be measured to complete the neighboring cell measurement.
[0062] In one embodiment, the measurement configuration information includes the time-domain positions of the SSBs corresponding to all beams in cells adjacent to beam position A, such as the time-domain positions of the SSBs corresponding to all beams in adjacent cell 2 (neighbor cell 2) and adjacent cell 3 (neighbor cell 3) in Figure 3a; and the time-domain positions of the SSBs corresponding to all beams in the serving cell are also configured. The computational load of the terminal is much lower than the energy consumption of measuring the serving cell and all beams in all cells adjacent to the serving cell in the prior art. The idle state measurement power consumption of the terminal located in beam position A can be reduced by 62.5% through the embodiment of this specification.
[0063] In another embodiment, the time-domain positions of the SSBs corresponding to neighboring wavelengths 1 and 2 in cell 2 (neighboring cell 2) adjacent to wavelength A, and the time-domain position of the SSB of neighboring wavelength 3 in neighboring cell 3 (neighboring cell 3) are configured only in the measurement configuration information. Furthermore, neighboring wavelengths 4 (SSB index 2), 5 (SSB index 3), and 6 (SSB index 6) adjacent to wavelength A in the serving cell are configured. Then, the terminal only needs to measure the time-domain positions of the SSB indices 3 and 4 corresponding to the two neighboring wavelengths 1 and 2 in neighboring cell 2, the SSB index 4 corresponding to one neighboring wavelength 3 in neighboring cell 3, and the time-domain positions of the SSB indices 2, 3, 5, and 6 in the serving cell. This reduces the computational load and power consumption of the terminal.
[0064] As an example, the cells adjacent to the coverage area corresponding to the beam of the transmitting SSB include all cells adjacent to the coverage area corresponding to the beam of the transmitting SSB during the overhead transit of the satellite to which the serving cell belongs.
[0065] In the embodiments of this specification, there are three beam coverage schemes in a satellite communication system. The first is a fixed ground method, where the beam continuously covers the same geographical area. The second is a quasi-fixed ground method, where the beam covers one geographical area for a limited time period and another geographical area for a different time period. The third is a mobile ground method, where the coverage area of the beam slides across the ground surface. The schemes in the embodiments of this specification can be applied to all three beam coverage schemes. Whenever the beam transmitting the SSB corresponding to the terminal's position changes, new measurement configuration information is obtained for measurement. The adjacent cells in the measurement configuration information broadcast by the satellite base station to a certain position include all cells in the serving cell that are adjacent to that position during the satellite's overhead transit.
[0066] Figure 4 is a schematic diagram illustrating the changes in cells adjacent to the wavelength position in an embodiment of this specification. This figure depicts the process where all cells move as the satellite moves, and the cells adjacent to the wavelength position continuously change, specifically including:
[0067] At time T0, terminal A enters the coverage area of satellite serving cell 0. Serving cell 0 includes multiple beam positions corresponding to beams transmitting SSBs. Terminal A is located in beam position 1. At this time, the neighboring cell of beam position 1 where the terminal is located is neighbor cell 2. In other embodiments, the neighboring cells of beam position 1 may also include other neighboring cells, which will not be elaborated here.
[0068] As the satellite moves, at time T1, terminal A is still in wave position 1, but all cells have moved upwards. Terminal A is still within the coverage area of serving cell 0 (service area 0), but the cell adjacent to wave position 1 has become neighbor cell 3.
[0069] As the satellite continues to move, at time T2, terminal A is still in wave position 1. All cells continue to move upwards, and terminal A is about to leave the current serving cell 0 (service area 0). At this time, the cells adjacent to the wave position 1 where terminal A is located become neighboring cell 3 and neighboring cell 4.
[0070] In summary, at time T0, the base station broadcasts the system information of the cells adjacent to the SSB to the cell 1 where terminal A is located through the beam transmitting SSB. The broadcast system information includes neighboring cells 2, 3 and 4.
[0071] For the three beam coverage schemes, the implementation is similar to the above embodiments. However, the beam of the transmission SSB selected by terminal A may change multiple times. Each time the beam changes, the terminal will re-receive the measurement configuration information associated with the selected transmission SSB beam. This will not be elaborated further here.
[0072] In contrast, terminal B, located in the middle of serving cell 0 (service area 0), is not adjacent to other cells at its current wave position 2. Only at time T2, when terminal B is still in wave position 2 and about to leave the current serving cell 0, is the cell adjacent to its current wave position 2 neighboring cell 4. Therefore, at time T0, the system information broadcast by the base station to the wave position 2 of terminal B includes only neighboring cell 4 as the cell adjacent to wave position 2.
[0073] As an example, the corresponding measurement configuration information includes converting the time domain location of the SSB in the adjacent cell into the clock of the serving cell.
[0074] In this step, when configuring the corresponding measurement configuration information, the time-domain location of the SSB in the neighboring cells can be converted into the clock of the serving cell before being configured to the terminal. Thus, the method described in this specification can be applied to both synchronous and asynchronous neighboring cells.
[0075] The method described in this specification can, on the one hand, accurately indicate the SSB used by adjacent beams, avoiding the waste of power caused by the terminal measuring a large number of invalid SSBs; on the other hand, it can reduce the number of measurement windows defined in the base station and terminal interface (i.e., the Uu interface), avoiding an increase in the number of SMTCs. For example, as shown in Figure 1, there are 12 adjacent beams around the serving cell, that is, there are 12 beams of other cells that overlap or cover the edge beams of the serving cell. Assuming that every two adjacent beams belong to one adjacent cell, the 12 adjacent beams belong to 6 adjacent cells. Each adjacent cell's SSB corresponds to an SSB burst set, which is an SSB measurement window. This requires the configuration of 6 SMTCs to meet the requirements. However, the existing 3GPP protocol can only configure a total of 4 SMTCs (SMTC1 and SMTC4). Therefore, by configuring the time domain position of the beam of the transmission SSB of the adjacent cells of the beam according to the beam, the expansion of the number of SMTCs in the 3GPP protocol can be avoided.
[0076] As an example, based on the neighbor cell configuration information, the temporal location of the SSB of the cell adjacent to the coverage area corresponding to the beam of the transmitted SSB is obtained.
[0077] In the embodiments of this specification, the base station can obtain neighbor cell configuration information through various methods, obtain the time domain location of the SSB of the cell adjacent to the coverage area (bow position) corresponding to the beam of the transmission SSB, and thus complete the configuration of the beam of the transmission SSB.
[0078] As an optional embodiment, the base station can obtain neighbor cell configuration information generated by ground operation control, wherein the ground operation control obtains the neighbor cell configuration information based on neighbor cell parameters of the beam specific to the transmission SSB.
[0079] In this embodiment, the ground control system plans and calculates neighbor cell configuration information based on the adjacency relationship between cells, the information of different beams transmitting SSBs, and the adjacency relationship between beam positions. This information is then assigned to the base station via the management plane. Alternatively, the neighbor cell configuration information can be assigned to the base station via other methods, which are not limited here.
[0080] As another optional embodiment, obtaining the temporal location of the SSB of a cell adjacent to the coverage area corresponding to the beam of the transmitted SSB based on the neighbor cell configuration information includes:
[0081] The coverage area information of the cell provided by the base station is transmitted between adjacent base stations through the interaction messages between base stations;
[0082] The neighbor cell configuration information is obtained based on the coverage area information of the neighboring cells.
[0083] In this embodiment, the Served Cell Information NR field in XN SETUP REQUEST, XN SETUP RESPONSE, NG-RAN NODE CONFIGURATION UPDATE, and NG-RAN NODE CONFIGURATION UPDATE ACKNOWLEDGE can be used to exchange the measurement timing configuration information of this cell with neighboring cells, and the cell SFN offset can be exchanged through SFN Offset.
[0084] As one embodiment, obtaining the temporal location of the SSB of a cell adjacent to the coverage area corresponding to the beam of the transmitted SSB, based on neighbor cell configuration information, includes:
[0085] Based on the neighbor cell configuration information, cells with adjacent relationships are identified;
[0086] The time-domain location of the SSB beam transmitting the SSB at the cell edge and the geographical information of the area covered by the beam are sent to adjacent cells.
[0087] In this embodiment, Figure 5 shows a schematic diagram of the interaction of neighbor cell configuration information between base stations according to an embodiment of this specification. In this figure, the base station can be, for example, a satellite-based base station. The wavelength of the satellite-based base station covering the edge of the cell is divided into multiple sub-regions. Taking a simple square coverage cell as an example, it can be divided into four regions: top, bottom, left, and right. The time-domain configuration of the SSB deployed on the wavelength of region 2 on the left (and the corresponding geographical location information) is sent to neighboring satellites 5 and 6 through the existing Xn interface; the time-domain configuration of the SSB deployed in region 3 (and the corresponding geographical location information) is sent to neighboring satellites 2 and 3; the time-domain configuration of the SSB deployed in region 4 (and the corresponding geographical location information) is sent to neighboring satellite 1; the time-domain configuration of the SSB deployed in region 1 (and the corresponding geographical location information) is sent to neighboring satellite 4. In this embodiment, the time-domain configuration of the SSB in the overlapping area of region 2 and region 4 can be part of the time-domain configuration of the SSB deployed in region 2 or region 4. This embodiment of the specification does not impose any restrictions.
[0088] The method described in this specification does not require indiscriminately configuring the time-domain positions of all SSBs used by the satellite-borne base station to all neighboring satellites. Instead, it selectively sends the time-domain positions of the SSBs of the beams used at the edge of the satellite-borne base station's coverage area to neighboring satellites adjacent to the edge region of the local satellite. This avoids configuring invalid measurement windows for the satellite terminal by the satellite-borne base station. The relative positional relationship between the edge region of the local satellite and neighboring satellites can be obtained through the ephemeris information of the local and neighboring satellites. For constellations with relatively stable neighboring satellite positional relationships, this can also be obtained through pre-configuration. This specification does not impose specific limitations on these embodiments.
[0089] Figure 6 shows a flowchart of a communication measurement configuration method according to an embodiment of this specification, applied to the terminal side, specifically including:
[0090] Step 601: Identify whether the beam of the transmission SSB selected by the terminal has changed;
[0091] Step 602: If the beam of the transmission SSB selected by the terminal changes, receive system information and obtain measurement configuration information specific to the transmission SSB selected by the terminal.
[0092] Through the measurement configuration method in the embodiments of this specification, the terminal identifies whether the selected beam has changed based on the information of the beam selected in the SSB (e.g., SSB index) and the information of the currently serving beam. If the selected transmission SSB beam has changed, the terminal measures the time-domain position of the SSB beam in the adjacent cells of the currently selected transmission SSB beam coverage area (wavelength) according to the measurement configuration information of the transmission SSB beam selected by the terminal. This avoids the terminal measuring the time-domain position of the SSB beam (wavelength) in all adjacent cells around its own cell, thereby saving the terminal's energy consumption.
[0093] As one embodiment, the measurement configuration information includes the time-domain location of the SSB of the cell adjacent to the coverage area corresponding to the beam of the transmission SSB selected by the terminal; and the time-domain location of the SSB of the serving cell to which the coverage area corresponding to the beam of the transmission SSB selected by the terminal belongs.
[0094] In this embodiment, when the terminal is in the coverage area (wavelength) corresponding to the original transmission SSB beam, but the beam of the transmission SSB selected by the terminal corresponding to the coverage area (wavelength) has changed, the received measurement configuration information includes the time domain location of the SSB of the cell adjacent to the wavelength corresponding to the beam selected by the terminal, and the time domain location of the SSB of the serving cell where the wavelength corresponding to the beam selected by the terminal is located.
[0095] As an example, the method further includes measuring the time-domain location of the SSB of a cell adjacent to the coverage area corresponding to the beam of the transmission SSB selected by the terminal; and measuring the time-domain location of the SSB of the serving cell to which the coverage area corresponding to the beam of the transmission SSB selected by the terminal belongs.
[0096] In this embodiment, the terminal measures the beam position in its serving cell and the beam positions in adjacent cells after the change of the transmission SSB beam, based on the measurement configuration information after the change of the transmission SSB beam. Thus, the terminal can perform real-time measurements of constantly changing neighboring cells within a small range based on the movement of the satellite-borne base station, achieving the goal of saving power consumption.
[0097] As one embodiment, the measurement configuration information includes the time-domain location of the SSBs in the coverage areas corresponding to all the beams of the transmitted SSBs in the cells adjacent to the coverage area corresponding to the beam of the transmitted SSB selected by the terminal; and the time-domain location of the SSBs in the coverage areas corresponding to all the beams of the transmitted SSBs in the serving cell to which the coverage area corresponding to the beam of the transmitted SSB selected by the terminal belongs.
[0098] In this embodiment, the measurement configuration information may include the time-domain positions of the SSBs of all positions in cells adjacent to the beam corresponding to the transmission SSB selected by the terminal, as shown in Figure 3a, including the time-domain positions of the SSBs of all positions (7 hexagons) in cell 2 (neighbor cell 2) adjacent to beam A, and the time-domain positions of the SSBs of all positions (7 hexagons) in cell 3 (neighbor cell 3); and the time-domain positions of the SSBs of all positions in the serving cell where the beam corresponding to the transmission SSB selected by the terminal is located. The adjacent cells refer to cells that have an adjacency or overlapping coverage relationship with the coverage area corresponding to the beam of the transmission SSB selected by the terminal. After the terminal performs measurements according to this measurement configuration information, it can avoid the prior art of measuring the time-domain positions of the SSBs of all positions in all adjacent cells surrounding the serving cell where the terminal is located, thus achieving the same goal of saving terminal energy consumption.
[0099] As one embodiment, the cells adjacent to the coverage area corresponding to the beam of the transmission SSB selected by the terminal include all cells adjacent to the coverage area corresponding to the beam of the transmission SSB selected by the terminal during the satellite overpass of the serving cell.
[0100] In this embodiment, when determining the cells adjacent to the coverage area (i.e., the beam position) corresponding to the transmission SSB selected by the terminal, it is necessary to consider all cells adjacent to the beam position during the satellite overhead.
[0101] As one embodiment, the measurement configuration information includes, in the adjacent cells, the time-domain location of the SSB corresponding to the coverage area of the beam corresponding to the transmitted SSB selected by the terminal, and the time-domain location of the SSB corresponding to the coverage area of the transmitted SSB corresponding to the beam corresponding to the transmitted SSB selected by the terminal in the serving cell.
[0102] In this embodiment, corresponding to the above embodiment, the measurement configuration information includes the time-domain position of the SSB of other positions adjacent to the coverage area of the changed position. This includes the time-domain position of the SSB of the adjacent positions in the cells adjacent to the changed position, such as the time-domain positions of the adjacent positions 1, 2, and 3 in the adjacent cells 2 (neighboring cell 2) and 3 (neighboring cell 3) of the adjacent position A in Figure 3a, namely SSB index 3, SSB index 4, and SSB index 4; it also includes the time-domain position of the SSB of the adjacent positions in the serving cell to which the beam corresponding to the changed transmission SSB belongs, such as the time-domain positions of the adjacent positions 4, 5, and 6 in the serving cell (this area) to which position A belongs in Figure 3a, namely SSB index 2, SSB index 3, and SSB index 6.
[0103] As one embodiment, identifying whether the beam transmitting the SSB has changed includes identifying whether the beam transmitting the SSB has changed based on the SSB index of the beam transmitting the SSB selected by the terminal.
[0104] In this embodiment, the terminal can determine whether a beam change has occurred based on the SSB index of its current position. If the SSB index changes, it is considered that the beam transmitting the SSB has changed, and the terminal proceeds to the step of receiving measurement configuration information specific to the beam transmitting the SSB selected by the terminal for configuration.
[0105] In other embodiments, the terminal may also receive pre-configured cell coverage area and all waveband coverage areas in the cell provided by the satellite base station. Based on the positioning information, the terminal determines which waveband coverage area the current location belongs to, thereby determining whether the waveband has changed.
[0106] Figure 7 shows a schematic diagram of the overall measurement configuration process according to an embodiment of this specification. This figure illustrates the working steps between the base station and the terminal in the measurement configuration process, specifically including:
[0107] Step 701: When the base station broadcasts the measurement configuration in a System Information Block (SIB), it associates the measurement configuration information with the wave position (i.e., the coverage area of the beam transmitting the SSB). That is, the base station broadcasts different measurement configuration information to different wave positions.
[0108] Step 702: When the terminal performs synchronization, it selects the SSB with SSB index n.
[0109] Step 703: The terminal receives a system information block (SIB) based on the monitoring occasion associated with SSB index n, and obtains the measurement configuration information of the wave position associated with SSB index n (that is, obtains the measurement configuration information associated with the beam of the transmission SSB corresponding to that wave position).
[0110] Step 704: The terminal executes the measurement process according to the measurement configuration information.
[0111] Step 705: Due to reasons such as terminal movement or satellite movement, the best SSB detected by the terminal changes, and the terminal selects another SSB with index m.
[0112] Step 706: The terminal recognizes that the selected SSB index has changed.
[0113] Step 707: The terminal re-receives the SIB containing the measurement configuration information.
[0114] Step 708: The terminal receives a System Information Block (SIB) based on the monitoring occasion associated with SSB index m, and obtains the measurement configuration information of the wave position associated with SSB index m.
[0115] Step 709: The terminal executes the measurement process according to the measurement configuration information.
[0116] While the process flow described above includes multiple operations that occur in a specific order, it should be clearly understood that these processes may include more or fewer operations that can be executed sequentially or in parallel (e.g., using parallel processors or a multithreaded environment).
