Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method, communication equipment and storage medium. Background Art

[0002] Although 5G has begun commercial deployment worldwide, geographical constraints and business models hinder its ability to guarantee network coverage in remote ocean and land areas. To overcome these geographical limitations, integrating satellite communications with terrestrial networks to create a seamless, global, integrated network covering land, sea, air, and space has become a hot topic in academia and industry. Currently, non-terrestrial networks (NTNs) are focusing on integrating satellite communications with 5G, addressing the critical issue of New Radio (NR) support for NTNs. Future integrated air, space, and ground networks will focus on deeper integration, combining multiple communication platforms to provide a wider range of diverse communication services.

[0003] In existing 5G networks, to reduce overhead and interference from reference signals from other cells, 5G (NR) removes the Cell-specific Reference Signal (CRS) and introduces the Synchronization Signal (SS) / Physical Broadcast Channel (PBCH) block (SSB) for cell signal measurement. This SS block consists of the SS and PBCH, and has a longer transmission period than the CRS. During the measurement process, the need to monitor and measure multiple cells leads to high terminal energy consumption. Summary of the Invention

[0061] The following describes the embodiments of the present application in conjunction with the accompanying drawings. The following describes the present application in conjunction with the accompanying drawings. The examples are only used to explain the present application and are not used to limit the scope of the present application.

[0062] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present application and are not intended to limit the present application. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions of the present application, not all of the structures.

[0063] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flow charts. Although the flow charts describe 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. A process can be terminated when its operation is completed, but can also have additional steps not included in the accompanying drawings. A process can correspond to a method, function, procedure, subroutine, subprogram, etc.

[0064] 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.

[0065] In addition, the embodiments and features in the embodiments of the present application may be combined with each other unless there is any conflict.

[0066] NTN's downlink coverage is limited by satellite payload constraints. Due to power limitations and link bandwidth constraints, it may not be possible to activate all beams of a satellite simultaneously. In such scenarios, the need to monitor and measure multiple cells results in high terminal energy consumption, a pressing issue.

[0067] In mobile communications, a User Equipment (UE) that enters a connected state not only continuously measures the serving cell, but also measures neighboring cells according to network configuration in preparation for cell handover due to deterioration of the serving cell signal or other reasons.

[0068] In 4G (LTE) networks, base stations (eNodeBs) continuously transmit CRSs so that UEs can measure the signal quality of neighboring cells.

[0069] To reduce overhead and interference from other cells' reference signals, 5G (NR) networks remove the CRS and introduce the SS / PBCH block (SSB) for cell signal measurement. This block, consisting of a synchronization signal (SS) and a physical broadcast channel (PBCH), has a longer transmission period than the CRS. The number of SSBs in a burst depends on the operating frequency band.

[0070] The SSB period in the network can be configured for each cell (unit) in 5, 10, 20, 40, 80 or 160 ms; while the UE does not need to measure the cell signal periodically like SSB, it can configure an appropriate measurement period based on the channel conditions to help avoid unnecessary measurements and reduce UE power consumption.

[0071] The window period of the SSB measurement time configuration (SMTC, SS / PBCH block Measurement Timing Configuration) can be set within the SSB broadcast period range, for example, 5, 10, 20, 40, 80 or 160 ms, and the window duration can be set to 1, 2, 3, 4 or 5 ms. Figure 1a This is a SSB transmission diagram provided by the existing technology. Figure 1b This is a schematic diagram of SMTC configuration provided by the prior art, such as Figure 1a As shown, the transmission of SSB on NR cell A is explained. Four SSBs (SSB0, SSB1, SSB2 and SSB3) can be transmitted on cell A.

[0072] Figure 2a This is another SSB transmission diagram provided by the prior art. Figure 2b This is another SMTC configuration diagram provided by the prior art, such as Figure 2a As shown, the transmission of SSB on NR cell B is explained. 8 SSBs (SSB0, SSB1, SSB2, SSB3...SSB7) can be transmitted on cell B.

[0073] Depend on Figure 1b and Figure 2b For comparison, 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 the measurement window and report the measurement results to the base station.

[0074] In view of this, the present application provides a communication method, in which, when the position of the first communication node moves or the cell switches, the second communication node can dynamically send a first indication message to the first communication node, and carry cell information, SSB information, SMTC information, the number of first type cycles N, the number of second type cycles K, the first type time and at least one of the second type time in the first indication message, so that the first communication node can determine the cell and / or SSB within the cell to be measured based on the dynamically updated cell information and SSB information, and determine the duration of measurement of the cell and / or SSB to be measured using the SMTC configuration information corresponding to the SMTC information (i.e., at least one of the number of first type cycles N, the number of second type cycles K, the first type time and the second type time), which can avoid the need for the first communication node to monitor and measure multiple cells or SSBs, thereby effectively reducing the energy consumption and measurement efficiency of the first communication node.

[0075] In the embodiment of the present application, the first communication node may be a user equipment (UE), and the second communication node may be a network device.

[0076] The UE in the embodiment of the present application can be called a terminal, which can be a mobile terminal, a vehicle-mounted terminal, etc. Among them, UE includes all devices that provide voice and / or data connectivity to users, such as wireless terminal devices, mobile terminal devices, device-to-device communication (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 terminal devices (Light UE), reduced capability user equipment (REDCAP UE), subscriber unit (Subscriber Unit), subscriber station (Subscriber Station), mobile station (Mobile Station), remote station (Remote Station), access point (Access Point, AP), remote terminal (Remote Terminal), access terminal (Access Terminal), user terminal (User Terminal), user agent (User Agent), or user equipment (User Device), etc., and can also be user equipment in future communication systems, which is not limited by this patent.

[0077] The network devices in the embodiments of the present application may be access network devices, core network devices, or servers, etc. The access network devices may be base stations in a terrestrial communication network or base stations in an NTN network. For example, an evolved base station eNB, a next-generation node gNB in ​​an NR system, a road side unit (RSU), a centralized unit CU and a distributed unit DU in a cloud access network system, or an access network device in a future communication system. The base stations in an NTN network may include: transparent type base stations, regenerate type base stations, 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 control unit (PCRF), etc. It may also be a core network device in a future communication system, and this application does not limit this.

[0078] It should be noted that the embodiments of the present application are preferably applicable to scenarios in which multiple cells under one satellite are activated at the same time, and the activated cells are non-adjacent, discrete, aggregated, and adjacent, or scenarios in which multiple cells under one satellite are activated at the same time. Figure 3 This is a schematic diagram of a communication scenario provided by an embodiment of the present application. Figure 3 As shown, it is assumed that there are 12 cells under the satellite, wherein each hexagon represents a cell, wherein 3 cells are in an activated state, that is, 3 cells in a filling pattern, and these three cells are not adjacent.

[0079] In one embodiment, Figure 4 This is a flow chart of a communication method provided by an embodiment of the present application. This embodiment is applied to the case of measuring a designated activated cell and / or SSB within an activated cell. This embodiment can be executed by the first communication node. Figure 4 As shown, this embodiment includes: S110.

[0080] S110: Receive first indication information. The first indication information includes at least one of the following:

[0081] Cell information, used to indicate the cell that the first communication node needs to measure;

[0082] Synchronization signal block SSB information;

[0083] SMTC information;

[0084] The number of first type cycles N;

[0085] The number of second type cycles K;

[0086] First type of time;

[0087] Second type of time.

[0088] The cell information described here is used to indicate the cell that the first communication node needs to measure. It can also be understood that the cell information is used to indicate the cell that the first communication node needs to measure, or the cell information is used to indicate the cell that the first communication node measures, or the cell information is used to indicate the cell that the first communication node can measure, or the cell information is used to indicate the cell to be measured by the first communication node.

[0089] In one embodiment, the first indication information includes at least one of the following:

[0090] Cell information, used to indicate the cell that the first communication node needs to measure;

[0091] SSB information, used to indicate the SSB that the first communication node needs to measure;

[0092] SMTC information, used to indicate the SMTC used by the first communication node;

[0093] The number of first type cycles N;

[0094] The number of second type cycles K;

[0095] First type of time;

[0096] Second type of time.

[0097] The SSB information described here is used to indicate the SSB that the first communication node needs to measure, and can also be understood as the SSB information being used to indicate the SSB that the first communication node needs to measure, or the SSB information being used to indicate the SSB that the first communication node measures, or the SSB information being used to indicate the SSB that the first communication node can measure, or the SSB information being used to indicate the SSB to be measured by the first communication node. In one example, after the first communication node receives the first indication information, the first indication information includes at least one of the first type period N, the second type period K, the first type time, and the second type time. The first communication node measures at least one of the cell information and the SSB information in the first indication information based on at least one of the first type period N, the second type period K, the first type time, and the second type time in the first indication information, and using the SMTC configuration information corresponding to the SMTC information.

[0098] In one example, when the second communication node itself detects or receives that the first communication node has moved into or near a new activated cell, or detects that the activated cell associated with the first communication node has changed, the second communication node sends updated first indication information to the first communication node, so that the first communication node performs cell or SSB measurement based on the updated first indication information.

[0099] In one example, a first communication node receives first indication information, which includes at least one of the following: cell information, used to indicate the cell that the first communication node needs to measure; SSB information; SMTC information; the first communication node can use the SMTC configuration information corresponding to the SMTC information to measure at least one of the cell information and SSB information in the first indication information.

[0100] In one example, after the first communication node receives the first indication information, if the first indication information does not include at least one of the first type period N, the second type period K, the first type time, and the second type time, the SMTC configuration information corresponding to the SMTC information is not used to measure at least one of the cell information and SSB information in the first indication information.

[0101] In one example, the first indication information may further include: PLMN information. In one example, the PLMN information is used to indicate the PLMN corresponding to the cell measured by the first communication node; or, the PLMN information is used to indicate the PLMN corresponding to the cell measured by the first communication node using SMTC.

[0102] In an example, the PLMN information may include at least one of the following: a PLMN identifier; and a PLMN index. For example, the PLMN identifier may be an operator identifier, such as an identifier of operator 1 or an identifier of operator 2.

[0103] In one example, the cell information indicates one or more cells that the first communication node needs to measure; alternatively, the cell information indicates one or more activated cells that the first communication node needs to measure. In one example, the cell information refers to information about activated cells. In one example, the cell corresponding to the cell information is one of the cells in the physical cell identifier list included in the SMTC configuration information.

[0104] In one example, the first communication node may be located inside the cell corresponding to the cell information, or may be located near the cell corresponding to the cell information.

[0105] In one example, when the serving cell of the first communication node is activated, the cell information is the serving cell of the first communication node, that is, the cell that the second communication node instructs the first communication node to measure is the same cell as the serving cell of the first communication node. In another example, when the serving cell of the first communication node is not activated, the cell that the second communication node instructs the first communication node to measure is not the same cell as the serving cell of the first communication node.

[0106] In an example, the SSB information may include information of one or more SSBs, and the SSB information is a subset or a full set of SSBs to be measured.

[0107] In one example, the number N of first type periods is used to characterize the number of valid periods or effective periods corresponding to the first indication information; illustratively, assuming that the second communication node estimates that the first communication node stays in the physical cell corresponding to the cell information for the length of two first type periods, the second communication node can configure the number N of first type periods to 2.

[0108] In one example, the second type period number K is used to indicate the number of periods that are separated or offset between the valid period or effective period corresponding to the first indication information and the period in which the first indication information is received. For example, assuming K=3, the first type period is separated from the SMTC period in which the first indication information is received by three SMTC periods.

[0109] In one example, both the first type period and the second type period may be SMTC periods.

[0110] In one example, the first type of time is used to represent the effective time or validity time corresponding to the first indication information; the second type of time is used to represent the time interval or offset between the effective time or validity time corresponding to the first indication information and the time when the first indication information was received. Exemplarily, the units of the first type of time and the second type of time can be milliseconds (ms) or microseconds (μs).

[0111] In the communication method of an embodiment of the present application, when the position of the first communication node moves or the cell switches, the second communication node can dynamically send a first indication message to the first communication node, and carry cell information, SSB information, SMTC information, the number of first type cycles N, the number of second type cycles K, the first type time and the second type time in the first indication message, so that the first communication node can determine the cell and / or SSB within the cell to be measured based on the dynamically updated cell information and SSB information, and determine the duration of measurement of the cell and / or SSB to be measured using the SMTC configuration information corresponding to the SMTC information (i.e., at least one of the number of first type cycles N, the number of second type cycles K, the first type time and the second type time). This can avoid the need for the first communication node to monitor and measure multiple cells or SSBs, thereby effectively reducing the energy consumption and measurement efficiency of the first communication node.

[0112] In one embodiment, the cell information is used to indicate the cells that the first communication node measures using SMTC. In one example, the cell information can be used to indicate one or more cells that the first communication node measures using SMTC, or the cell information can be used to indicate one or more activated cells that the first communication node measures using SMTC.

[0113] In one embodiment, the cell information includes one of the following: a cell identifier; a cell index.

[0114] In one example, a cell identifier can be a number or name that uniquely identifies a cell and is used to distinguish different cells. The cell identifier can be a cell ID, cell name, or other similar cell identifier. 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 cells can be numbered in a certain order.

[0115] In one example, a cell index is a cell's position number within a specific list or set, which can be used to quickly locate and access the cell. A cell index can be referred to as a cell index. Cell identifiers and cell indices correspond to different numbering spaces. A cell identifier can be unique across the entire network or within a specific base station; however, a cell index is generally unique within a specific list or set.

[0116] In one example, when the cell information is a cell identity, the cell identity is a subset of the physical cell identity list. In one example, when the cell information is a cell index, the cell identity associated with the cell index is also a subset of the physical cell identity list.

[0117] In one embodiment, the cell identity includes: a physical cell identity (PCI) and / or a cell global identifier (CGI).

[0118] In one example, PCI refers to the short identification code used by the physical layer to distinguish adjacent cells, which is used by the first communication node to quickly identify and synchronize cell signals; CGI refers to the global address that uniquely identifies the cell at the network layer, which is used by the core network to accurately locate and manage the cell.

[0119] In one embodiment, the SSB information is used to indicate the SSB that the first communication node measures using the SMTC.

[0120] In one example, the SSB information may be used to indicate one or more SSBs that the first communication node needs to measure using the SMTC. In one example, the SSB information of each cell may be the same or different.

[0121] In one embodiment, the SSB information includes one of the following: an SSB index; an SSB identifier.

[0122] In one example, the SSB identifier may be a number or name that uniquely identifies an SSB, used to distinguish different SSBs; the SSB identifier may be an SSB ID, an SSB Name, or other identifiers. Each SSB may be numbered according to a numbering rule to obtain a unique SSB identifier for each SSB.

[0123] For example, within 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 called an SSB Index. The numbering spaces corresponding to the SSB identifier and the SSB index are different, that is, the SSB identifier can be unique in the entire network, or unique in a certain cell or base station; and the SSB index is generally unique in a certain list or set. Assuming that the base station is configured with 4 beams for scanning to send different versions of the same SSB (covering cells from different directions), then these SSBs can be numbered as: SSB 0, SSB 1, SSB 2 and SSB3, that is, the indexes of these SSBs in this SSB set are SSB 0, SSB 1, SSB 2 and SSB 3, respectively.

[0124] In one embodiment, the SMTC information is used to indicate the SMTC used by the first communication node. In one example, the SMTC information is used to indicate one or more SMTCs used by the first communication node to perform cell and / or SSB measurements.

[0125] In one example, when the second communication node indicates to the first communication node through first indication information a plurality of SMTCs used by the first communication node, the SMTC applicable to each physical cell may be determined based on a mapping relationship between the SMTC and the physical cell identifier list.

[0126] In one embodiment, the SMTC information includes one of the following: an SMTC index; an SMTC identifier.

[0127] In one example, the SMTC identifier may be a number or name that uniquely identifies an SMTC, used to distinguish different SMTCs; the SMTC identifier may be an SMTC ID or an SMTC Name or other. Each SMTC may be numbered according to a numbering rule to obtain a unique SMTC identifier for each SMTC.

[0128] In one example, the SMTC index is a position number of an SMTC in a specific list or collection, which can be used to quickly locate and access the SMTC. The SMTC index can be called an SMTC Index.

[0129] In one embodiment, the timing of measurement includes at least one of the following:

[0130] within the SMTC period in which the first indication information is received;

[0131] Within N SMTC periods after receiving the first indication information;

[0132] within N SMTC periods after K SMTC periods after receiving the first indication information;

[0133] within a first type of time after receiving the first indication information;

[0134] Within the first type of time after the second type of time after the first indication information is received.

[0135] In one example, the measurement opportunity may also be referred to as a measurement opportunity, measurement time, measurement gap, or measurement configuration window. In one example, the measurement opportunity is a specific time window or configuration opportunity for the first communication node to perform measurements such as channel quality and neighboring cell signal strength. It may be a time period for executing a measurement task pre-configured by the second communication node for the first communication node to ensure that the measurement behavior of the first communication node is synchronized with the scheduling of the second communication node, thereby ensuring normal data transmission.

[0136] Note that the measurement opportunity mentioned here is within the SMTC period. This means that the measurement opportunity can be a time range within the SMTC period, meaning that measurements can be performed within a time range within the SMTC period or within a portion of the period. Measurements do not need to be performed at every point in the SMTC period. In some cases, the measurement time can also be the entire SMTC period, meaning that measurements can be performed at all times within the SMTC period.

[0137] Figure 5a This is a schematic diagram of a configuration of a measurement opportunity provided by an embodiment of the present application, such as Figure 5a As shown, the measurement opportunity may be one or more SMTC periods.

[0138] In one example, the measurement timing is the SMTC period in which the first indication information is received, that is, the measurement timing refers to the SMTC period in which the first indication information is received. Assuming that the SMTC period in which the first indication information is received is SMTC period 2 (i.e., the second SMTC period), the measurement timing is the second SMTC period.

[0139] In one example, the timing of measurement is within N SMTC cycles after the first indication information is received, that is, the timing of measurement refers to the N SMTC cycles most recent after the SMTC cycle in which the first communication node receives the first indication information. Assuming that the SMTC cycle in which the first indication information is received is SMTC cycle 2 (i.e., the second SMTC cycle), and N=3, the timing of measurement may include: SMTC cycle 3 (i.e., the third SMTC cycle), SMTC cycle 4 (i.e., the fourth SMTC cycle), and SMTC cycle 5 (i.e., the fifth SMTC cycle).

[0140] In one example, the timing of measurement is within N SMTC cycles after K SMTC cycles after the first indication information is received, that is, the timing of measurement refers to N SMTC cycles after K SMTC cycles after the SMTC cycle in which the first communication node receives the first indication information. At this time, the measurement timing is not adjacent to the SMTC cycle in which the first indication information is received. Assuming that the SMTC cycle in which the first indication information is received is SMTC cycle 2 (i.e., the second SMTC cycle), K=2 and N=3, the measurement timing may include: SMTC cycle 5 (i.e., the fifth SMTC cycle), SMTC cycle 6 (i.e., the sixth SMTC cycle), and SMTC cycle 7 (i.e., the seventh SMTC cycle).

[0141] In one example, the measurement timing may be within the duration of the SMTC period.

[0142] In an example, the timing of measurement may include at least one of the following:

[0143] During the duration of the SMTC period in which the first indication information is received;

[0144] within a duration of N SMTC periods after receiving the first indication information;

[0145] The duration is within N SMTC cycles after K SMTC cycles after the first indication information is received.

[0146] In an example, the measurement timing may be the entire time within the duration of the corresponding SMTC period, or may be a portion of the time within the duration.

[0147] It should be noted that the measurement opportunity here refers to the duration within the SMTC period. It can be understood that the measurement opportunity can be any time within the duration within the SMTC period, that is, measurement can be performed at any time within the duration within the SMTC period, for example, measurement can be performed during part of the duration, or measurement can be performed during the entire duration.

[0148] Figure 5b This is a schematic diagram of another configuration of measurement timing provided by an embodiment of the present application. Figure 5b As shown, the measurement opportunity may be within the duration of one or more SMTC periods.

[0149] In one example, the measurement timing is the SMTC period when the first indication information is received, that is, the measurement timing refers to the SMTC period at the time point corresponding to the reception of the first indication information. Figure 5cThis is another configuration diagram of a measurement opportunity provided by an embodiment of the present application. For example, Figure 5c As shown, assuming that the SMTC period when the first indication information is received is SMTC period 2 (ie, the second SMTC period), the measurement opportunity is within the duration of the second SMTC period.

[0150] In one example, the measurement timing is within N SMTC periods after the first indication information is received, that is, the measurement timing refers to the N SMTC periods most recent after the SMTC period in which the first communication node receives the first indication information. Figure 5d FIG. 1 is a schematic diagram of another configuration of a measurement opportunity provided by an embodiment of the present application. For example, Figure 5d As shown, assuming that the SMTC period in which the first indication information is received is SMTC period 1 (i.e., the first SMTC period), and N=1, the measurement timing may include: within an SMTC period after SMTC period 1, i.e., within the duration of SMTC period 2 (i.e., the second SMTC period).

[0151] In one example, the measurement timing is within N SMTC periods after the first indication information is received, that is, the measurement timing refers to the N SMTC periods most recent after the SMTC period in which the first communication node receives the first indication information. Figure 5e FIG. 1 is a schematic diagram of another configuration of a measurement opportunity provided by an embodiment of the present application. For example, Figure 5e As shown, assuming that the SMTC period in which the first indication information is received is SMTC period 2 (i.e., the second SMTC period), and N=3, the measurement opportunities may include: the duration of SMTC period 3 (i.e., the third SMTC period), the duration of SMTC period 4 (i.e., the fourth SMTC period), and the duration of SMTC period 5 (i.e., the fifth SMTC period).

[0152] It should be noted that Figure 5d and Figure 5e The difference includes: the time of receiving the first indication information may be located at different positions within the SMTC period, for example, it may be located before the duration of the SMTC period, or it may be located after the duration of the SMTC period.

[0153] In one example, the measurement timing is within N SMTC cycles after K SMTC cycles after the first indication information is received, that is, the measurement timing refers to N SMTC cycles after K SMTC cycles after the SMTC cycle in which the first communication node receives the first indication information. At this time, the measurement timing is not adjacent to the SMTC cycle in which the first indication information is received. Figure 5fFIG. 1 is a schematic diagram of another configuration of a measurement opportunity provided by an embodiment of the present application. For example, Figure 5f As shown, assuming that the SMTC period in which the first indication information is received is SMTC period 2 (i.e., the second SMTC period), K=2 and N=3, the measurement opportunities may include: the duration within SMTC period 5 (i.e., the fifth SMTC period), the duration within SMTC period 6 (i.e., the sixth SMTC period), and the duration within SMTC period 7 (i.e., the seventh SMTC period).

[0154] In one example, the value of K may also be other integers greater than or equal to 1, and this is not limited.

[0155] In one example, the measurement timing is Figure 5b-5f The duration of the SMTC period shown is as follows, wherein the measurement opportunity may be a part of the duration or the entire duration.

[0156] In one example, the first type of time after receiving the first indication information refers to the first type of time closest to the SMTC cycle in which the first communication node receives the first indication information. Exemplarily, assuming that the SMTC cycle in which the first indication information is received is SMTC cycle 2 (i.e., the second SMTC cycle), and the first type of time = 3ms, then the measurement opportunity may include: within the closest 3ms after the second SMTC cycle.

[0157] In one example, within the first type of time after the second type of time after receiving the first indication information refers to the first type of time after the second type of time after the SMTC period in which the first communication node receives the first indication information, that is, the measurement opportunity is not adjacent to the SMTC period in which the first indication information is received. Exemplarily, assuming that the SMTC period in which the first indication information is received is SMTC period 2 (that is, the second SMTC period), the second type of time is 2ms, and the first type of time is 3ms, the measurement opportunity may include: within 3ms after 2ms after the second SMTC period.

[0158] In one embodiment, K and / or N are both integers greater than or equal to 1; and / or,

[0159] The first type time and / or the second type time are real numbers greater than or equal to 0.

[0160] In one example, both K and N may be real numbers greater than or equal to 0. In one example, K and N may also be decimals, for example, K=1.5, N=2.5, that is, the measurement timing may be within 2.5 SMTC periods after 1.5 SMTC periods after receiving the first indication information.

[0161] In one example, the first type of time and / or the second type of time can be integers or decimals, and the first type of time and / or the second type of time has a time unit, for example, the time unit of the first type of time and / or the second type of time is ms, and the values ​​of the first type of time and the second type of time are independent, for example, the first type of time can be 2ms and the second type of time can be 3ms.

[0165] In one example, the values ​​of K and / or N may be specified in the protocol, that is, the second communication node does not need to indicate the values ​​of K and N to the first communication node, so as to reduce signaling overhead.

[0166] In one example, the values ​​of K and / or N may be indicated, that is, the second communication node may indicate the values ​​of K and N to the first communication node to ensure flexible configuration of the values ​​of K and N.

[0189] In one embodiment, a satellite includes one or more cells. In one example, when a satellite includes multiple cells, the cell types of the multiple cells included in the satellite may be the same or different.

[0191] In one embodiment, the distribution state of cells that are simultaneously activated under one satellite includes at least one of the following: clustered; scattered.

[0192] In one example, there may be one or more cells that are activated simultaneously under one satellite; when there are multiple cells that are activated under one satellite, the multiple activated cells may be clustered, that is, the cells are adjacent to each other; or, the multiple activated cells may be dispersed, that is, the cells are non-adjacent.

[0193] In one example, cells that are simultaneously activated under a satellite are clustered, which can be applicable to a scenario where multiple first communication nodes appear in a certain area; cells that are simultaneously activated under a satellite are scattered, which can be applicable to a scenario where multiple first communication nodes appear in several areas.

[0194] In one embodiment, the cell in the activated state includes at least one of the following: a cell in which all beams are activated; a cell in which some beams are activated.

[0195] In one example, the second communication node knows which cells are in an activated state. In one example, an activated cell is a cell in which all beams are activated, meaning that all beams of all types are activated within the cell; an activated cell is a cell in which some beams are activated, meaning that all beams of some types or some beams of all types are activated within the cell.

[0196] In one embodiment, the cell in the activated state includes at least one of the following: a cell in which all SSB beams are activated; a cell in which some SSB beams are activated.

[0197] In one example, an activated cell is a cell in which all SSB beams are activated, which means a cell in which at least all SSB beams are activated; an activated cell is a cell in which some SSB beams are activated, which means a cell in which at least some SSB beams are activated.

[0198] In one embodiment, each cell is covered by at least one beam.

[0199] In one example, each cell may be covered by the same beam type, for example, each cell may be covered by one or more SSB beams. In one example, each cell may be covered by multiple beam types, for example, each cell may be covered by one or more SSB beams and one or more data beams.

[0200] In one embodiment, at the same time, the activation status of the beams included in each cell includes one of the following: all beams are activated at the same time; all beams are deactivated at the same time; some beams are activated, and some beams are deactivated.

[0201] In one example, all beams refer to all beams of all beam types contained in a cell; partial beams refer to all beams of some beam types contained in a cell, or partial beams of all beam types. For example, if a cell includes SSB beams, control beams, and data beams, all beams of the three beam types in the cell are activated at the same time, or all beams of the three beam types in the cell are not activated at the same time; or all SSB beams in the cell are activated at the same time, and all control beams and all data beams are not activated at the same time; or some SSB beams and some control beams in the cell are activated at the same time, and some SSB beams, beam control beams, and all data beams are not activated at the same time.

In one example, the number of SMTCs determined by the first communication node can be one or more, or a maximum of 4 SMTCs, and the number of SMTCs configured by the second communication node can be one or more, or a maximum of 4 SMTCs.

[0205] In one embodiment, one or more SMTCs, or a maximum of four SMTCs, are deployed under one satellite; and / or,

[0206] One or more SMTCs, or a maximum of four SMTCs, are configured for each frequency, frequency layer, or frequency point.

[0207] In one example, one or more SMTCs may be configured for each frequency, frequency layer, or frequency point in a satellite, or a maximum of four SMTCs may be configured for each frequency, frequency layer, or frequency point in a satellite.

[0208] In one embodiment, SMTC is used for part or all cells under a frequency, frequency layer or frequency point.

[0209] In one embodiment, SMTC is used for part or all cells under one frequency, frequency layer or frequency point; or, SMTC is used for part or all cells under one frequency layer; or, SMTC is used for part or all cells under one frequency point.

[0210] In one example, when one SMTC is configured, some cells under one frequency, frequency layer, or frequency point use the same SMTC, or all cells under one frequency, frequency layer, or frequency point use the same SMTC.

[0211] In one example, when multiple SMTCs are configured, a portion of cells under one frequency, frequency layer, or frequency point adopts one SMTC, and another portion of cells under one frequency, frequency layer, or frequency point adopts another SMTC.

[0212] In one embodiment, each SMTC is applicable to at least one cell. In one example, each SMTC is applicable to at least one cell, which can be understood as configuring the SMTC at a cell granularity.

[0213] In one embodiment, one SMTC is configured for one cell. In one example, the SMTC associated with each cell may be different, or the SMTCs associated with every two adjacent cells may be different.

[0214] In one embodiment, when the distribution state of cells is clustered, a maximum of four SMTCs are configured for each frequency, frequency layer, or frequency point; and / or,

[0215] When the distribution state of cells is dispersed, the number of SMTCs is 1 or a maximum of 4.

[0216] By configuring 4 or more SMTCs as described above, it can be achieved that the SMTCs of two adjacent cells under the coverage of one satellite are different.

[0217] In one embodiment, a satellite may include one or more cells, and the distribution of cells that are simultaneously activated under a satellite is clustered, so the number of SMTCs configured under each frequency, frequency layer or frequency point is at most 4.

[0218] In one embodiment, a satellite may include one or more cells, and the distribution of cells that are simultaneously activated under a satellite is clustered, so the number of SMTCs configured under each frequency, frequency layer or frequency point is at most 4.

[0219] In one embodiment, a satellite may include one or more cells, and the distribution of cells that are simultaneously activated under a satellite is dispersed. The number of SMTCs configured under a satellite may be one or a maximum of four.

[0222] In one embodiment, one or more SMTCs are configured under one satellite, or a maximum of four SMTCs are configured; and one SMTC is configured for each cell.

[0223] In one embodiment, one or more SMTCs are configured under one satellite, or a maximum of four SMTCs are configured; and one SMTC is configured for each cell, and the SMTCs configured for each two adjacent cells are different.

[0224] In one embodiment, one or more SMTCs are configured for each frequency, frequency layer, or frequency point, or a maximum of four SMTCs are configured; and one SMTC is configured for each cell.

[0225] In one embodiment, one or more SMTCs are configured for each frequency, frequency layer, or frequency point, or a maximum of four SMTCs are configured; and one SMTC is configured for each cell, and the SMTCs configured for each two adjacent cells are different.

[0226] In one embodiment, one or more SMTCs are configured under each frequency, frequency layer, or frequency point; if the distribution state of cells that are simultaneously activated under a satellite is clustered, a maximum of 4 SMTCs can be configured under each frequency, frequency layer, or frequency point; and one SMTC is configured for each cell.

[0227] In one embodiment, one or more SMTCs are configured under each frequency, frequency layer, or frequency point; if the distribution state of cells that are simultaneously activated under a satellite is clustered, a maximum of 4 SMTCs can be configured under each frequency, frequency layer, or frequency point; and, one SMTC is configured for each cell, and the SMTCs configured for each two adjacent cells are different.

[0228] In one embodiment, a satellite may include one or more cells, each cell is covered by one or more beams, each beam may carry an SSB, the number of SMTCs configured under a satellite may be one or more, and each cell is configured with one SMTC.

[0229] In one embodiment, a satellite may include one or more cells, each cell is covered by one or more beams, each beam may carry an SSB, the number of SMTCs configured under a satellite may be one or more, and each cell is configured with an SMTC, and the SMTCs of two adjacent cells under a satellite are different.

[0230] In one embodiment, the communication method applied to the first communication node further includes: receiving SMTC configuration information. In one example, before receiving the first indication information sent by the second communication node, the first communication node receives the SMTC configuration information, so that after receiving the first indication information, the first communication node can directly perform cell or SSB measurement based on the SMTC configuration information corresponding to the SMTC information included in the first indication information, thereby ensuring measurement efficiency and quality.

[0231] It should be noted that the English name of the SMTC configuration information may be: SSB-MTC Information.

[0232] In one embodiment, the SMTC configuration information includes at least one of the following: a period; an offset; a duration; a physical cell identifier list; and an SSB to be measured.

[0233] In one example, the period may be referred to as periodicity, or other expressions; the offset may be referred to as offset, or other expressions; the duration may also be referred to as a time window, a measurement window, or a measurement time window, which may be referred to as duration, or other expressions, and is used to characterize the duration of the measurement performed by the first communication node; the physical cell identifier list may be referred to as Pci-List, or other expressions, and is used to characterize to which cells the parameters of the SMTC are applicable, that is, to which cells the period, offset, and duration included in the SMTC configuration information are applicable; the SSB to be measured may be referred to as SSB-ToMeasure, or other expressions, and the SSB to be measured may include the type of SSB to be measured, the number of SSBs to be measured, or the type of SSB to be measured, etc.; the SSB type of each cell may be different, and a cell may contain multiple SSBs, and the SSB to be measured may be used to characterize which types of SSBs to be measured, that is, which types of SSBs the period, offset, and duration included in the SMTC configuration information are applicable to.

[0234] In one example, one SMTC configuration information may also be a set of SMTC configuration information, and each SMTC configuration information includes at least one of the following: a period; an offset; a duration; a physical cell identifier list; and an SSB to be measured. Furthermore, the period included in one SMTC configuration information may be different from the period included in another SMTC configuration information, the offset included in one SMTC configuration information may be different from the offset included in another SMTC configuration information, the duration included in one SMTC configuration information may be different from the duration included in another SMTC configuration information, the physical cell identifier list included in one SMTC configuration information may be different from the physical cell identifier list included in another SMTC configuration information, and the SSB to be measured included in one SMTC configuration information may be different from the SSB to be measured included in another SMTC configuration information.

[0235] In one example, 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 coincides with the start time of the period.

[0236] In one example, when multiple SMTC configuration information is configured, each SMTC configuration information applies to different cells. For example, two SMTC configuration information (e.g., SMTC1 and SMTC2) are configured, where the configuration information of SMTC1 applies to cells 1, 2, ..., and 5; and the configuration information of SMTC2 applies to cells 6, 7, ..., and 10. It can be understood that the number N of first-type cycles corresponding to SMTC1 and SMTC2 can be infinite, that is, SMTC1 and SMTC2 are always effective, but they apply to different cells.

[0237] In one embodiment, the period in the SMTC configuration information is smaller than the SSB period. In one example, the period in the SMTC configuration information can be smaller, for example, smaller than the SSB period. In one example, the SSB period refers to the time interval at which the second communication node periodically transmits the SSB, for example, the SSB period can be 5ms, 10ms, 20ms, etc.

[0238] In one embodiment, the SMTC configuration information is carried by at least one of the following messages: a system message; an RRC reconfiguration message; an RRC release message; or a New Radio (NR) measurement object.

[0239] In one example, the system message may include a System Information Block 2 (SIB2) and SIB4. In one example, SIB2 is used to configure radio resources when the first communication node makes an initial access; SIB4 is used for cell reselection, i.e., the first communication node can evaluate the signal quality of a neighboring cell based on SIB4 to determine whether to switch to a better cell.

[0240] In one example, the RRC reconfiguration message may also be referred to as an RRC Reconfiguration message; the RRC release message may also be referred to as an RRC Release message; and the NR measurement object may also be referred to as a Meas Object NR, or an NR measurement event.

[0297] It should be noted that, for the explanation of parameters such as the first indication information, cell information, SMTC information, SSB information, number of first type cycles, number of second type cycles, first type time, and second type time in the communication method applied to the second communication node, please refer to the description of the corresponding parameters in the above-mentioned communication method applied to the first communication node, and will not be repeated here.

[0298] In the following embodiments, the process of determining relevant parameters corresponding to measurement using SMTC is described by taking the first communication node as a UE and the second communication node as a base station as an example.

[0299] On the UE side:

[0300] The UE receives the first indication information; the first indication information is used to indicate relevant information of the SMTC.

[0301] In an example, the first indication information may include at least one of the following:

[0302] Cell information, used to indicate the cell that the first communication node needs to measure;

[0303] Synchronization signal block SSB information;

[0304] SMTC information;

[0305] The number of first type cycles N;

[0306] The number of second type cycles K;

[0307] First type of time;

[0308] Second type of time.

[0309] In one example, the cell information is used to indicate the cell that the UE measures using the SMTC.

[0310] In one example, the measured reality may include at least one of the following:

[0311] within the SMTC period in which the first indication information is received;

[0312] within the latest N SMTC periods after receiving the first indication information;

[0313] within the latest N SMTC periods after the latest K SMTC periods after the first indication information is received;

[0314] within the most recent first type of time after receiving the first indication information;

[0315] within the most recent first type time after the most recent second type time after the first indication information is received.

[0316] In one example, both K and N are integers greater than or equal to 1.

[0317] In one example, K and N may be specified by the protocol or indicated.

[0318] In one example, K and N may be indicated in the first indication information.

[0319] In one example, the SSB information may be used to indicate the SSB that the UE uses to perform measurements using the SMTC.

[0320] In one example, the SSB information may be SSB Index or SSB ID, etc.

[0321] In one example, the first indication information is carried by at least one of the following messages: NAS message; AS message; RRC message; SDAP message; PDCP message; RLC message; MAC message; or PHY message.

[0322] In an example, the SMTC information may be one or more SMTC configuration information.

[0323] In one example, the SMTC may be used for all or part of the cells under a frequency, frequency layer, or frequency point, that is, one SMTC may be configured for all or part of the cells under a frequency, frequency layer, or frequency point.

[0324] In one example, STMC can be applied to all or some cells under M frequencies, frequency layers, or frequency points; where the value of M is the same as the number of pre-configured SMTCs. For example, if the number of pre-configured SMTCs is 3, the pre-configured SMTC can be applied to all or some cells under the three frequencies, frequency layers, or frequency points.

[0325] In one example, the SMTCs configured at multiple frequencies, frequency layers, or frequency points may be the same or different.

[0326] In one example, SMTC can be used for all or part of the cells under one satellite.

[0327] In one example, one SMTC is configured for all cells under one frequency, frequency layer or frequency point, and the first indication information includes the SMTC identifier, or the indication information does not include the SMTC identifier, and it is assumed that the first indication information corresponds to the one SMTC.

[0328] In one example, multiple SMTCs are configured for all cells under a frequency, frequency layer or frequency point, and the first indication information may include an SMTC identifier; or, if the first indication information does not include an SMTC identifier, the first indication information corresponds to the SMTC associated with the PCI in the first indication information.

[0329] In one example, different adjacent cells on the same frequency layer may have different SSB periods.

[0330] In one example, in an NR NTN cell, SSB beam transmission in different spatial directions is possible, just like in an NR TN cell: the entire cell can be covered by different SSB beams in half a frame.

[0331] In one example, if a cell is defined by multiple satellite beams, these satellite beams are activated or deactivated simultaneously, that is, beam hopping is applied equally to all satellite beams of a given cell.
