[0035] Next, the technical solutions in the embodiments of the present invention will be described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Next, some terms involved in the present application will be briefly described as follows:

[0037] The research on the next-generation (new radio communication system) (New radio, NR) system mainly considers two frequency bands currently, namely frequency band FR1 (Frequency range 1) and frequency band FR2 (Frequency range 2). Among them, the frequency domain ranges included in FR1 and FR2 are shown in Table 1. It should be understood that the embodiments of the present application can be applied to the FR1 and FR2 frequency bands, and can also be applied to other frequency bands, such as the frequency band from 52.6 GHz to 71 GHz, or the frequency band from 71 GHz to 100 GHz, etc. The present application does not limit this.

[0038] Frequency Band Definition Corresponding Frequency Band Range FR1 410 MHz – 7.125 GHz FR2 24.25 GHz – 52.6 GHz

[0039] Table 1

[0040] The research of the NR system includes the technology of Non Terrestrial Network (NTN) devices. NTN generally uses satellite communication to provide communication services to ground users. Compared with terrestrial cellular network communication, satellite communication has many unique advantages. First of all, satellite communication is not restricted by the user's geographical location. For example, general terrestrial communication cannot cover areas such as the ocean, mountains, and deserts where it is impossible to set up communication equipment or where communication coverage is not provided due to sparse population. For satellite communication, since one satellite can cover a large area of the ground and the satellite can orbit the earth, theoretically every corner of the earth can be covered by satellite communication. Secondly, satellite communication has great social value. Satellite communication can cover remote mountainous areas, poor and backward countries or regions at a relatively low cost, enabling people in these areas to enjoy advanced voice communication and mobile Internet technologies, which is conducive to narrowing the digital divide with developed regions and promoting the development of these regions. Thirdly, satellite communication has a long communication distance, and the communication cost does not increase significantly as the communication distance increases; finally, satellite communication has high stability and is not restricted by natural disasters.

[0041] Communication satellites are divided into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit) satellites, HEO (High Elliptical Orbit) satellites, etc. according to different orbital heights. At present, the main research focuses on LEO and GEO.

[0042] For LEO satellites, the orbital height range is 500 km to 1500 km, and the corresponding orbital period is about 1.5 hours to 2 hours. The signal propagation delay of single-hop communication between terminals is generally less than 20 ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is small, and the requirement for the terminal's transmit power is not high.

[0043] For GEO satellites, the orbital height is 35786 km, and the rotation period around the earth is 24 hours. The signal propagation delay of single-hop communication between users is generally 250 ms.

[0044] In order to ensure the satellite coverage and improve the system capacity of the entire satellite communication system, the satellite uses multi-beam to cover the ground. One satellite can form dozens or even hundreds of beams to cover the ground; one satellite beam can cover a ground area with a diameter of dozens to hundreds of kilometers.

[0045] Initial access in the NR system is completed through Synchronizing Signal / PBCH Block (SSB or SS / PBCH block). The SSB includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), and the Physical Broadcast Channel (PBCH).

[0046] Measurements in the NR system can be obtained by measuring the SSB or the Channel State Information Reference Signal (CSI Reference Signal, CSI-RS).

[0047] In the NR system, the SSB patterns supported by FR1 include 3 cases (Case A, Case B, Case C), and the SSB patterns supported by FR2 include 2 cases (Case D, Case E). Among them, one SSB transmission opportunity can include one or more SSBs. One SSB includes 4 symbols in the time domain, and a set of SSB transmission opportunities should be completed within one half-frame (5 ms). Assume that the index of the first symbol in the first time slot within one half-frame is symbol 0:

[0048] (1) Case A - 15 kHz subcarrier spacing:

[0049] 1) The index of the first symbol of the SSB includes {2, 8} + 14 * n;

[0050] 2) For non-shared spectrum:

[0051] ① When the carrier frequency is less than or equal to 3 GHz, n = 0, 1;

[0052] ② When the carrier frequency within FR1 is greater than 3 GHz, n = 0, 1, 2, 3;

[0053] 3) For shared spectrum, n = 0, 1, 2, 3, 4.

[0054] (2) Case B - 30 kHz subcarrier spacing:

[0055] 1) The index of the first symbol of the SSB includes {4, 8, 16, 20} + 28 * n;

[0056] ① When the carrier frequency is less than or equal to 3 GHz, n = 0;

[0057] ②The carrier frequency within FR1 is greater than 3 GHz, n = 0, 1.

[0058] (3) Case C - 30 kHz subcarrier spacing:

[0059] 1) The index of the first symbol of the SSB includes {2, 8} + 14 * n;

[0060] 2) For non - shared spectrum and belonging to paired spectrum (e.g., Frequency Division Duplex (FDD) scenario);

[0061] ①The carrier frequency is less than or equal to 3 GHz, n = 0, 1;

[0062] ②The carrier frequency within FR1 is greater than 3 GHz, n = 0, 1, 2, 3;

[0063] 3) For non - shared spectrum and belonging to non - paired spectrum (e.g., Time Division Duplex (TDD) scenario);

[0064] ①The carrier frequency is less than or equal to 2.4 GHz, n = 0, 1;

[0065] ②The carrier frequency within FR1 is greater than 2.4 GHz, n = 0, 1, 2, 3.

[0066] 4) For shared spectrum, n = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

[0067] (4) Case D - 120 kHz subcarrier spacing:

[0068] 1) The index of the first symbol of the SSB includes {4, 8, 16, 20} + 28 * n;

[0069] ①For the carrier frequency within FR2, n = 0, 1, 2, 3, 5, 6, 7, 8, 10, 11, 12, 13, 15, 16, 17, 18.

[0070] (5) Case E - 240 kHz subcarrier spacing:

[0071] 1) The index of the first symbol of the SSB includes {8, 12, 16, 20, 32, 36, 40, 44} + 56 * n;

[0072] ①For the carrier frequency within FR2, n = 0, 1, 2, 3, 5, 6, 7, 8.

[0073] As Figure 1A shown, it is a schematic diagram of partial SSB patterns regarding FR1 in different cases in the NR system. As Figure 1BAs shown, it is a schematic diagram of partial SSB patterns regarding FR2 in different scenarios in the NR system. As Figure 1C shown, it is a schematic diagram of a set of SSB transmission opportunities within a half-frame, taking the SSB pattern in Case A as an example.

[0074] For downlink beam measurement, it should be understood that a beam is an objectively existing physical entity. The measurement of a beam is achieved by measuring the reference signal transmitted on this beam. The measurement metrics of downlink beams include L1-RSRP (Reference Signal Received Power) and / or L1-SINR (Signal to Interference plus Noise Ratio), where L1 represents the measurement of layer 1, or physical layer measurement. L1 measurement is directly processed at the physical layer, with the advantage of less latency. Optionally, the network device can indicate to the terminal device the specific measurement RSRP metric to be used, which is L1-RSRP or L1-SINR, through configuration signaling. The network device can configure N reference signal resources for the terminal device. The terminal device reports K >= 1 pieces of information to the network device according to the measurement results. Each piece of information includes beam indication information (such as SSB index) and the corresponding L1-RSRP information. Among them, the value of K can be configured by the network device.

[0075] For a wireless mobile communication system, the accurate measurement of cell quality and beam quality is the basis for its effective implementation of radio resource management and mobility management. SSB can be used as a measurement reference signal for radio resource management (RRM) measurement. For measurements based on SSB, the network device configures the measurement configuration parameters of SSB to the terminal device through high-layer signaling for the terminal device to perform corresponding measurement operations. The measurement configuration parameters received by the terminal device can include SSB frequency point, SSB subcarrier spacing, synchronization signal block measurement time configuration (SMTC) configuration, reference signal configuration, and other configurations, etc.

[0076] In NR, the reference signal for Radio Link Monitoring (RLM-RS) is configured by higher-layer signaling such as Radio Link Monitoring RS. The configurable RLM-RS includes: Channel State Information Reference Signal (CSI-RS) and / or SSB. The configuration of an RLM-RS includes the index of an SSB. The network device can configure one or more RLM-RS for the terminal device on each BandWidth Part (BWP). The maximum number of configurable RLM-RS is related to the frequency range. For example, it is 2 below 3 GHz, 4 between 3 GHz and 6 GHz, and 8 above 6 GHz. The configuration of RLM-RS can also include the measurement purpose of RLM-RS. For example, it can be used for beam failure detection (e.g., configured as beam Failure), or for cell failure detection (e.g., configured as Radio Link Failure, RLF), or for both beam failure detection and cell failure detection (e.g., configured as both).

[0077] The beam failure recovery mechanism is supported in the NR system. When it is found that the current beam transmission quality is poor to a certain extent, the terminal device actively searches for a new beam with good link quality and notifies the network device, so as to re-establish a high-quality and reliable communication link through the new beam. This processing method is called the Beam Failure Recovery (BFR) mechanism, simply referred to as the beam recovery mechanism.

[0078] (1) Beam Failure Detection (BFD), as described above.

[0079] In the NR system, the beam failure recovery mechanism is designed for the Primary Cell (PCell) and the Primary Secondary Cell (PSCell). The terminal device measures the downlink transmission and judges the link quality corresponding to the downlink transmission beam. If the corresponding link quality is very poor, it is considered that the downlink beam has a beam failure.

[0080] (2) New Beam Identification (NBI)

[0081] The network device pre-configures a set of reference signals (such as a set of SSBs) for the terminal device. Among them, each reference signal corresponds to an alternative downlink transmission beam, that is, the network device configures a set of alternative downlink transmission beams for the terminal device. The terminal device determines a new beam by measuring the L1-RSRP of these alternative beams. The network device will pre-configure an RSRP threshold value, and the terminal device selects a beam from the alternative beams whose L1-RSRP measurement value is greater than this RSRP threshold as the available new beam.

[0082] (3) Beam Failure Recovery Request (BFRQ)

[0083] The terminal device needs to notify the network device of the available new beam found so that the network device knows that it can use this new beam for downlink transmission. In NR, it is supported to use the Physical Random Access Channel (PRACH) to send BFRQ. That is, when beam failure occurs, the terminal device will trigger a random access process, and indicate to the network side through the MSG1 of the random access that the terminal device has experienced beam failure and the information of the new beam selected by the terminal device.

[0084] (4) Network side response

[0085] If the BFR triggers non-competitive random access, the UE will monitor the random access response using the new beam in the search space dedicated to BFR. That is, the network device will pre-configure the CORESET and search space corresponding to BFR in advance. This dedicated CORESET is only associated with this dedicated search space and not with other search spaces. If within the random access response window, the terminal device monitors the Downlink Control Information (DCI) sent by the network device to it on the new beam, it is considered that the beam recovery is successful.

[0086] In the NTN scenario shown in the embodiments of this application, a satellite can serve multiple footprints through multiple beams. A footprint can be considered as a coverage area on the ground, which can be called a coverage cell. Among them, the multiple footprints correspond to the same cell identity (ID), or rather correspond to the same satellite cell. As Figure 2A shown, it is a schematic diagram of the NTN scenario applied in the embodiments of the present invention.

[0087] A footprint can correspond to one or more beams. Specifically, taking the case where a footprint corresponds to one beam as an example, there can be three situations in the NTN network deployment scenario based on beams:

[0088] Scenario 1: The frequency re-use factor is 1. As shown in Figure 2B the figure, it is a schematic diagram of the frequency re-use factor of 1 in the NTN scenario.

[0089] Scenario 2: The frequency re-use factor is 3. As shown in Figure 2C the figure, it is a schematic diagram of the frequency re-use factor of 3 in the NTN scenario.

[0090] Scenario 3: The frequency re-use factor is 2. As shown in Figure 2D the figure, it is a schematic diagram of the frequency re-use factor of 2 in the NTN scenario.

[0091] In the NTN system, when a network device (such as a satellite) serves multiple ground coverage cells (footprints) through multiple beams, these multiple footprints can correspond to the same cell identity (Identity, ID). Additionally, in the case where the frequency re-use factor is greater than 1, different footprints can correspond to different frequency resources. In these scenarios, it is not clear how the network device configures measurement resources for the terminal device, and how the terminal device performs downlink beam measurement or RRM measurement or RLM measurement or BFR, etc., based on the configuration information of the measurement resources sent by the network device.

[0092] Exemplarily, Figure 3A it is a schematic diagram of the architecture of a communication system provided by an embodiment of the present application. As shown in Figure 3A the figure, the communication system 100 may include a network device 110. The network device 110 may be a device that communicates with a terminal device 120 (or referred to as a communication terminal, terminal). The network device 110 may provide communication coverage for a specific geographical area and may communicate with terminal devices located within that coverage area.

In Figure 3B In the architecture of the shown communication system, the satellite 1102 can have the function of a base station, and direct communication can be performed between the terminal device 1101 and the satellite 1102. In the system architecture, the satellite 1102 can be referred to as a network device. Optionally, the communication system can include multiple network devices 1102, and the coverage range of each network device 1102 can include other numbers of terminal devices, which is not limited in the embodiments of the present application.

Please refer to Figure 3C , including a terminal device 1201, a satellite 1202, and a base station 1203. Wireless communication can be performed between the terminal device 1201 and the satellite 1202, and communication can be performed between the satellite 1202 and the base station 1203. The network formed among the terminal device 1201, the satellite 1202, and the base station 1203 can also be referred to as NTN. In Figure 3C In the architecture of the shown communication system, the satellite 1202 may not have the function of a base station, and the communication between the terminal device 1201 and the base station 1203 needs to be relayed through the satellite 1202. In this system architecture, the base station 1203 can be referred to as a network device. Optionally, the communication system can include multiple network devices 1203, and the coverage range of each network device 1203 can include other numbers of terminal devices, which is not limited in the embodiments of the present application.

A wearable device, also known as a wearable intelligent device, is a general term for devices developed by applying wearable technology to the intelligent design of daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is either directly worn on the body or integrated into the user's clothes or accessories. A wearable device is not just a hardware device, but also realizes powerful functions through software support, data interaction, and cloud interaction.

[0108] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technologies, mobile communication systems will not only support traditional communications but also support, for example, Device to Device (D2D) communication, Machine to Machine (M2M) communication, Machine Type Communication (MTC), Vehicle to Vehicle (V2V) communication, or Vehicle to everything (V2X) communication, etc. The embodiments of this application can also be applied to these communication systems.

[0112] It should be understood that the terms "system" and "network" are often used interchangeably in this application. The term "and / or" in this application merely describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally represents an "or" relationship between the associated objects before and after.

[0113] It should be understood that the "indication" mentioned in the embodiments of this application can be a direct indication, an indirect indication, or a representation of an association relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C and B can be obtained through C; it can also mean that there is an association relationship between A and B.

[0117] The technical solution of the present invention will be further described below by way of embodiments. The embodiments of the present application include some or all of the following content:

[0118] In the present application, Figure 2C Taking the corresponding case 2, one coverage cell corresponding to one beam, and the SSB transmission pattern being Case A as an example for illustration, for case 1, or case 3, or one coverage cell corresponding to multiple beams, or other scenarios of SSB transmission patterns, the same can be obtained analogously through the method in the present application, which will not be elaborated one by one below. Taking each segment of frequency resource in case 2 corresponding to one BWP as an example for network deployment, then one coverage cell corresponds to one BWP, and different SSB indexes can correspond to different BWPs in the NTN network. As Figure 4A shown, it is an example diagram of the NTN network deployment scenario based on beams in the embodiments of the present invention. In Figure 4A the shown figure, B represents a beam, or the index of the SSB. For example, B0 refers to SSB0, B1 refers to SSB1, and so on. FP represents the coverage cell on the ground shown as a hexagon. For example, FP0 indicates that the ID of this coverage cell is 0, FP1 indicates that the ID of this coverage cell is 1, and so on. BWP0 indicates that the ID of the BWP corresponding to this coverage cell is 0, BWP1 indicates that the ID of the BWP corresponding to this coverage cell is 1, and so on. Exemplarily, BWP0 corresponds to FP0, 3, 6, 9…; BWP1 corresponds to FP1, 4, 7, 10…; BWP2 corresponds to FP2, 5, 8, 11….

[0119] Figure 4B - Figure 4E It is an example diagram of several ways for a network device to perform SSB transmission within the SMTC window in the embodiments of the present invention. The terminal device can perform corresponding measurements based on the SSB transmitted by the network device within the SMTC window. It should be understood that this SSB transmission method is only an example, and the embodiments of the present application can also be applied to other scenarios of SSB transmission. The present application does not limit this. In these several examples, it is assumed that the number of SSBs that the network device needs to send is 3, that is, a group of SSB transmissions within the SMTC window includes 3 SSBs. Among them, different beams corresponding to different BWPs are used to transmit different or the same SSB indexes, and the BWP identifier and the SSB index can be in a one-to-one or one-to-many relationship, as Figure 4AAs shown in the figure, the corresponding beam in BWP0 is SSB0, the corresponding beam in BWP1 is SSB1, and the corresponding beam in BWP2 is SSB2. The following describes several methods for the network device to perform SSB transmission, as follows:

[0120] Method 1: Refer to Figure 4B , according to the association relationship between the SSB index and the BWP identifier, the SSB is transmitted on its corresponding BWP. That is, SSB0 is transmitted through BWP0, SSB1 is transmitted through BWP1, and SSB2 is transmitted through BWP2. Among them, the SSB can be a cell-defining SSB or a non-cell defining SSB.

[0121] Method 2: Refer to Figure 4C , the SSB transmission method is different from that in Rel-15. Assuming that BWP0 is the initial BWP in the cell, then this group of SSBs is transmitted through BWP0, and this group of SSBs is a cell-defining SSB. In addition, some SSBs in this group of SSBs are also transmitted on BWP1 and BWP2, and there is an association relationship between the SSBs on BWP1 or BWP2 and some SSBs in this group of SSBs transmitted on BWP0. That is, SSB1 is also transmitted through BWP1, and SSB2 is also transmitted through BWP2. Among them, the SSBs transmitted on BWP1 and BWP2 are non-cell defining SSBs. Optionally, the SSBs transmitted on BWP1 and BWP2 also need to be transmitted on the synchronization grid.

[0122] Method 3: Refer to Figure 4D , the SSB transmission method is similar to that in Rel-15. Assuming that BWP0 is the initial BWP in the cell, then this group of SSBs is transmitted through BWP0, and this group of SSBs is a cell-defining SSB. In addition, this group of SSBs is also transmitted on BWP1 and BWP2, and the SSBs transmitted on BWP1 and BWP2 are non-cell defining SSBs. Optionally, the SSBs transmitted on BWP1 and BWP2 also need to be transmitted on the synchronization grid.

[0123] Method 4: Refer to Figure 4E , the SSB transmission method is the same as that in Rel-15. Assuming that BWP0 is the initial BWP in the cell, then this group of SSBs is transmitted through BWP0, and this group of SSBs is a cell-defining SSB. There may be no SSB transmission on BWP1 and / or BWP2.

[0155] As an example, the correlation relationship between the serving cell ID and the SSB index includes: s = p mod M, where p represents the serving cell ID, s represents the SSB index, and M represents the number of SSBs transmitted. For example, assuming that the number of SSBs transmitted in the SSB transmission opportunity in the cell is 6 SSBs, the SSB indices s corresponding to the serving cell IDs p from 0 to 9 are: 0, 1, 2, 3, 4, 5, 0, 1, 2, 3.

[0156] As an example, the correlation relationship between the SSB index and the BWP ID includes: q = s mod N, where s represents the SSB index, q represents the BWP ID, and N represents the number of BWPs.

[0192] The identifier of the reference signal resource corresponding to the new beam; the covered cell corresponding to the reference signal resource corresponding to the new beam; and the BWP corresponding to the reference signal resource corresponding to the new beam.

[0193] In the technical solution provided by the embodiments of the present invention, the terminal device receives first configuration information sent by the network device, where the first configuration information includes configuration information of a first reference signal resource, and the first reference signal resource includes a synchronization signal block (SSB) resource and / or a channel state information reference signal (CSI-RS) resource; the terminal device obtains a first measurement result according to the first configuration information. The terminal device can perform measurements according to the measurement resource configuration information sent by the network device to obtain measurement results, which further enhances the existing measurement solution and improves the measurements in the NTN system.

[0194] Taking the reference signal resource as the SSB resource as an example, the technical solution of the present invention will be described respectively from the aspects of downlink beam measurement based on SSB, mobility measurement based on SSB, RLM measurement based on SSB, and beam failure recovery mechanism based on SSB. For the measurements of other reference signal resources, reference can be made to the SSB resource and will not be elaborated one by one. As follows:

[0195] I. Downlink beam measurement based on SSB

[0196] For example: The measurement metrics of the downlink beam may include L1-RSRP (Reference Signal Received Power) and / or L1-SINR (Signal to Interference plus Noise Ratio), where L1 represents the measurement of layer 1, or in other words, the physical layer measurement. The L1 measurement can be directly processed at the physical layer, and the advantage is that the delay is small. Optionally, the network device can indicate the specific measurement metric adopted by the terminal device, namely L1-RSRP or L1-SINR, through configuration signaling, that is, the above-mentioned first configuration information.

[0197] The terminal device reports K ≥ 1 reporting messages to the network device, and each reporting message includes a measurement result; the reporting message may further include beam indication information (such as an SSB index), and the corresponding L1-RSRP information; the reporting message may further include the frequency-domain position corresponding to the SSB, and / or the covered cell corresponding to the SSB. When K > 1, the quantization result of the maximum value among the K L1-RSRP values is directly reported, and the quantization results of the differences between the other K - 1 L1-RSRP values and the maximum L1-RSRP value are reported, that is, the other K - 1 L1-RSRP reporting difference values. For the measurement of L1-SINR, the reporting is similar and will not be elaborated here.

[0198] Optionally, according to whether the terminal device can receive data transmitted simultaneously on K downlink beams, the reporting method of the measurement result can be divided into the following two categories: non-group based reporting and group based reporting.

[0199] In non-group based reporting, the terminal device measures according to N reference signal resources configured by the network device. Among them, the N reference signal resources are configured in M BWPs, and each BWP includes one or more reference signal resources, and N is greater than or equal to M. According to the measurement result, K reporting messages are selected for reporting, and the value of K is configured by the network device and can be 1, 2, 3, or 4. The K reference signal resources correspond to K beams. The network device cannot transmit signals to this terminal device simultaneously from multiple beams among the K beams because this terminal device cannot receive signals transmitted on multiple downlink beams simultaneously.

[0200] Exemplarily, for a terminal device located in the covered cell of FP14, BWP2, and B2, the reference signal resources configured by the network device for the terminal device to measure the downlink beam include one or more of the following: SSB0 corresponding to FP0 and BWP0, SSB1 corresponding to FP13 and BWP1, SSB0 corresponding to FP12 and BWP0, SSB1 corresponding to FP22 and BWP1, SSB0 corresponding to FP9 and BWP0, SSB1 corresponding to FP10 and BWP1, so that the terminal device can timely switch to a suitable BWP or beam for transmission during the movement process.

[0201] When the terminal device reports K reporting messages, it selects the reporting beam according to the configured M BWPs:

[0202] Optionally, if K is less than or equal to M, the terminal device selects the beam (or SSB) with the strongest L1-RSRP from each of the K BWPs among the M BWPs, where the K BWPs are the K BWPs with the strongest L1-RSRP among the M BWPs.

[0203] Optionally, if K is greater than M, the terminal device selects a beam (or SSB) with the strongest L1-RSRP from each of the M BWPs. For the remaining (K - M) beams, the terminal device can select them according to its own implementation algorithm. For example, it can only consider the K beams with the strongest L1-RSRP, or it can consider the direction of arrival of different beams (i.e., consider the spatial correlation between different received reference signals) to select the remaining (K - M) beams.

[0204] II. Mobility Measurement Based on SSB

[0205] For the mobility measurement based on SSB, the network device configures the first configuration information of the SSB to the terminal device through higher layer signaling for the terminal device to perform corresponding measurement operations. The first configuration information received by the terminal device may include SSB frequency point, SSB subcarrier spacing, synchronization signal block measurement time configuration (SMTC), reference signal configuration, and other configurations, etc. The first configuration information may also include the frequency domain position corresponding to the SSB, and / or other configuration information such as the covered cell corresponding to the SSB.

[0206] The SSB frequency point is the center frequency point position of the SSB to be measured. The SSB subcarrier spacing is the subcarrier spacing information of the SSB to be measured, for example, it can be 15 kHz or 30 kHz, etc. The SMTC is the time domain resource configuration information for SSB measurement, which is mainly used to configure a set of measurement time windows for SSB measurement, and the size, position, period and other parameters of the window can be adjusted through configuration parameters. Currently, up to two sets of SMTC parameters can be configured for measurement. The configuration information of the first reference signal resource (such as ReferenceSignal Config) is used to indicate the specific configuration information of the specific measurement reference signal resource. For the measurement based on SSB, the configuration information of the first reference signal resource includes SSB configuration parameters, such as the information of the SSB to be measured (such as SSB-ToMeasure).

[0207] The SSB indication information to be measured indicates the location information of the SSBs to be measured in the SSB burst set by using a bitmap, which may include the time domain location information corresponding to the SSB, the frequency domain location information corresponding to the SSB, and / or the coverage cell information corresponding to the SSB. By way of example and not limitation, one row of the bitmap corresponds to one frequency domain location or one coverage cell, and the first bit (or the leftmost bit) in one row of the bitmap corresponds to SSB index 0, the second bit corresponds to SSB index 1, and so on. When the bit indication value is 0, it means that the corresponding SSB within the SMTC window does not need to be measured, and when the bit indication value is 1, it means that the corresponding SSB within the SMTC window needs to be measured. When the terminal device is not configured with the SSB indication to be measured, it means that all SSBs within the SMTC window need to be measured.

[0208] For example, assume that the bitmap corresponding to the SSB indication to be measured includes [10000000] associated with BWP0, [01000000] associated with BWP1, and [00100000] associated with BWP2. Then it indicates that the SSBs within the SMTC window that the terminal device should measure include: SSB0 on BWP0, SSB15 on BWP1, and SSB2 on BWP2. Accordingly, the terminal device can perform mobility management measurements based on this first configuration information.

[0209] III. Radio Link Monitoring (RLM) measurements based on SSB

[0210] The configuration of a Radio Link Monitoring (RLM) reference signal (RLM-RS) includes the index of an SSB, and may also include the frequency domain location corresponding to the SSB, and / or the coverage cell corresponding to the SSB. The network device can configure one or more RLM-RSs for the terminal device on each BWP. The network device can also configure other configuration information such as the BWP or coverage cell for the terminal device to perform RLM measurements.

[0211] Exemplarily, for a terminal device located in the coverage cell of FP14, BWP2, and B2, the reference signal resources configured by the network device for the terminal device to perform RLM measurements include one or more of the following: SSB0 corresponding to FP0 and BWP0, SSB1 corresponding to FP13 and BWP1, SSB0 corresponding to FP12 and BWP0, SSB1 corresponding to FP22 and BWP1, SSB0 corresponding to FP9 and BWP0, and SSB1 corresponding to FP10 and BWP1, so that the terminal device can timely switch to a suitable BWP or beam for transmission during the movement process.

[0212] The configuration of RLM-RS may also include the measurement purpose of RLM-RS. For example, it can be used for beam failure detection (e.g., configured as beam failure), or for cell failure detection (e.g., configured as rlf), or for both beam failure detection and cell failure detection (e.g., configured as both).

[0213] (1) Radio Link Failure Detection

[0214] The metric for cell failure detection is the Hypothetical Physical Downlink Control Channel (PDCCH) block error rate (BLER). Since the actual BLER of PDCCH transmission cannot be directly obtained, the terminal device calculates the corresponding possible BLER based on the measured SINR, so it is called the Hypothetical PDCCH BLER. Among the multiple configured RLM-RS, the UE assumes that the RLM-RS has the same antenna port as the evaluated Hypothetical PDCCH.

[0215] The NR system supports two sets of Hypothetical PDCCH BLERs. Among them, the first set of thresholds is consistent with Long Term Evolution (LTE). The Hypothetical PDCCH BLER corresponding to the In Synchronization (IS) threshold is 2%; the Hypothetical PDCCH BLER corresponding to the Out Of Synchronization (OOS) threshold is 10%. The purpose of introducing the other set of thresholds is that this set of thresholds corresponds to a higher Hypothetical PDCCH BLER, which is convenient for maintaining the wireless link connection at locations with poor radio signals, avoiding triggering a wireless link failure and causing a connection failure, thus being beneficial to maintaining the continuity of services such as Voice over Internet Protocol (VoIP). Which set of Hypothetical PDCCH BLER thresholds to use can be configured by the network device.

[0216] If the terminal device is configured with a BWP or a serving cell for which RLM measurement is to be performed, the terminal device performs RLM measurement using the RLM-RS configured on the BWP determined according to the configuration information; or when no RLM-RS is configured on the BWP determined according to the configuration information, the CSI-RS corresponding to the activated TCI state corresponding to the control resource set (CORESET) used for PDCCH reception on the BWP determined according to the configuration information is used as the RLM-RS for RLM measurement. Among them, the terminal device may be configured with one or more BWPs or serving cells for RLM measurement.

[0217] After the RLM-RS is configured, the terminal device performs measurement according to the configured RLM-RS, and the measurement result is compared with the synchronization (In Synchronization, IS) / out-of-synchronization (Out Of Synchronization, OOS) threshold, so as to obtain the IS / OOS state of the radio link, and the evaluation result of the IS / OOS state is reported to the upper layer of the terminal device or the network device periodically. When reporting the evaluation result, the corresponding BWP information such as BWP ID or serving cell information such as serving cell ID also needs to be reported. For each BWP or each serving cell, if the measurement result of at least one RLM-RS among all the configured RLM-RSs is higher than the IS threshold, the physical layer reports the IS state of this BWP or serving cell to the upper layer or the network device; or, if the measurement results of all the configured RLM-RSs are lower than the OOS threshold, the physical layer reports the OOS state of this BWP or serving cell to the upper layer or the network device.

[0218] Exemplarily, in the non-DRX state, the reporting period of the IS / OOS state is the maximum value between the shortest period among the periods of all the configured RLM-RS resources and 10 ms. In the DRX state, the reporting period of the IS / OOS state is the maximum value between the shortest period among the periods of all the configured RLM-RS resources and the DRX period.

[0219] (2) Beam Failure Detection (BFD)

[0220] The metric for beam failure detection is the assumed PDCCH BLER. The physical layer detects the assumed BLER of the beam corresponding to the PDCCH. If the assumed PDCCH BLER of all beams is worse than the specified threshold, it is recorded as a beam failure instance (BFI), and the occurrence of a BFI is reported to the Medium Access Control (MAC) layer. Alternatively, if the terminal device measures that the quality of other configured beams is higher than the specified threshold or the quality of other configured beams is higher than the quality of the currently used beam. It can be understood that the beam failure at this time is not a true beam failure, but a beam failure recovery mechanism is used to promptly determine whether the terminal device has undergone a change in the coverage cell, so as to perform timely beam switching.

[0221] Exemplarily, for a terminal device located in a coverage cell of FP14, BWP2, and B2, the reference signal resources for measurement configured by the network device for the terminal device include one or more of the following: SSB0 corresponding to FP0 and BWP0, SSB1 corresponding to FP13 and BWP1, SSB0 corresponding to FP12 and BWP0, SSB1 corresponding to FP22 and BWP1, SSB0 corresponding to FP9 and BWP0, and SSB1 corresponding to FP10 and BWP1, so that the terminal device can report a suitable BWP or beam to the network device in a timely manner during movement.

[0222] The physical layer can report to the MAC side periodically. If there is no report at a certain time, it is considered that there is no BFI. The MAC layer maintains the relevant beam failure detection timer (beam Failure Detection Timer) and beam failure counter (BFI_COUNTER). To ensure the reliability of beam failure detection, each time the MAC layer receives a BFI report, the beam failure detection timer is started or restarted, and the beam failure counter count is increased by 1. If the beam failure detection timer times out, the terminal will reset the counter to 0, thereby ensuring that the judgment of beam failure is based on continuous BFI reports. If the beam failure counter reaches the specified maximum value during the timer operation, the terminal device considers that a beam failure has occurred.

[0223] 4. SSB-based beam failure recovery mechanism

[0224] The terminal device measures the downlink transmission to determine the link quality corresponding to the downlink transmission beam. If the corresponding link quality is very poor, it is considered that the downlink beam has a beam failure. The terminal device also measures a set of candidate beams and selects a beam that meets a certain threshold as the new beam. Then, the terminal device notifies the network device of the beam failure through the BeamFailure Recovery Request (BFRQ) procedure and reports the new beam. After receiving the BFRQ information sent by the terminal device, the network device knows that the terminal device has a beam failure and selects to send the PDCCH on the new beam. When the terminal device receives the PDCCH sent by the network device on the new beam, it is considered that the response information from the network side has been correctly received. Thus, the beam failure recovery procedure is successfully completed. Its main functional modules (or main steps) are divided into four:

[0225] (1) Beam Failure Detection (BFD) As described above, it will not be elaborated here.

[0226] (2) New Beam Identification (NBI)

[0227] The network device pre-configures a set of reference signals (such as a set of SSBs) for the terminal device and the corresponding BWP or covered cell for each reference signal. Among them, each reference signal and the corresponding BWP or covered cell correspond to a candidate downlink transmission beam, that is, the network device configures a set of candidate downlink transmission beams for the terminal device. The terminal device determines a new beam by measuring the L1-RSRP of these candidate beams. The network device will pre-configure an RSRP threshold value, and the terminal device selects a beam as the available new beam from the candidate beams whose L1-RSRP measurement value is greater than this RSRP threshold.

[0228] (3) Beam Failure Recovery Request (BFRQ)

[0229] The terminal device needs to notify the network device of the available new beam found so that the network device knows that it can use this new beam for downlink transmission.

[0230] In NR, it is supported to use the Physical Random Access Channel (PRACH) to send the BFRQ. That is, when a beam failure occurs, the terminal device triggers a random access procedure and indicates to the network side through the MSG1 of the random access that the terminal device has a beam failure and the information of the new beam selected by the terminal device.

[0231] When dedicated PRACH resources are pre-configured for BFRQ based on network devices, the random access type is non-competitive random access. The network device pre-configures a set of candidate beams (such as SSB) and corresponding BWPs or covered cells for the terminal device, and configures corresponding PRACH resources and random preambles for each SSB (where each SSB configuration corresponds to a BWP or a covered cell). Then, when the terminal device determines that a certain beam is a new beam, it uses the PRACH resources corresponding to the new beam to send the corresponding random preamble. After receiving it, the network device knows that the terminal device has experienced a beam failure. The network device will determine the new beam selected by the terminal device based on the received PRACH information and send a random access response on the new beam.

[0232] In the case where the network device may not configure dedicated BFR resources (including a set of candidate beams and their corresponding dedicated PARCH resources) for the terminal device, or the terminal device may not be able to find an available new beam among the candidate beams configured by the network device (for example, the network device does not configure a reference signal for NBI and the corresponding PRACH resources, that is, the terminal device has no alternative beam to measure, or the L1-RSRP measurement values corresponding to all candidate beams are worse than the threshold configured by the network), the terminal device will initiate the existing competitive-based random access procedure according to the SSB signal quality measurement results in the cell to complete the reconnection with the network device. In this case, since the network device does not pre-configure dedicated PRACH resources for beam failure requests for the terminal device, when the terminal device sends the corresponding Msg1, the network device does not know whether the random access procedure initiated by the terminal device is due to beam failure or other reasons. In the NR enhanced version R16, in order to further enhance the beam failure recovery mechanism in this case, the terminal device can carry a MAC CE dedicated to indicating BFR information in Msg3 or MsgA of the competitive-based random access to indicate to the network device side that this random access process is triggered by beam failure. At the same time, this BFR MAC control element (Control Element, CE) can also carry the new beam information selected by the terminal device, the BWP information corresponding to the new beam information, and / or the covered cell information.

[0233] (4) Network side response

[0234] If the BFR triggers non-competitive random access, the UE will monitor the random access response using a new beam in the BFR-exclusive search space on the corresponding BWP. That is to say, the network device will pre-configure the CORESET and search space on the BWP corresponding to the BFR. This dedicated CORESET is only associated with this dedicated search space and not with other search spaces. If within the random access response window, the terminal device monitors the downlink control information (DCI) sent by the network device on the new beam on the corresponding BWP, it is considered that the beam recovery is successful.

[0235] For the case where the network device does not configure BFR-exclusive resources, that is, the competitive-based random access mentioned above, the network device does not need to configure this dedicated search space, and the UE can monitor the PDCCH in the common search space.

[0236] In the technical solution provided by the embodiments of the present invention, the terminal device receives the first configuration information sent by the network device. The first configuration information includes the configuration information of the first reference signal resource. The first reference signal resource includes the synchronization signal block (SSB) resource and / or the channel state information reference signal (CSI-RS) resource. The terminal device obtains the first measurement result according to the first configuration information. The terminal device can perform measurements according to the measurement resource configuration information sent by the network device to obtain measurement results, which further enhances the existing measurement scheme and also improves the measurements in the NTN system. Exemplarily, in the NTN network, when the satellite network device serves multiple covered cells on the ground through multiple beams and these multiple covered cells correspond to the same cell ID, the network device sends the first configuration information to the terminal device. The first configuration information may include the configuration information of the first reference signal resource, and the first configuration information is used for the terminal device to obtain the first measurement result.

[0307] Corresponding to the method of at least one embodiment applied to a terminal device, the embodiment of the present application also provides one or more terminal devices. The terminal device of the embodiment of the present application can implement any one of the implementation modes of the above method. Figure 8 As shown, it is a schematic diagram of another embodiment of a terminal device in an embodiment of the present invention. The terminal device is described by taking a mobile phone as an example, and may include: a radio frequency (RF) circuit 810, a memory 820, an input unit 830, a display unit 840, a sensor 850, an audio circuit 860, a wireless fidelity (WiFi) module 870, a processor 880, and a power supply 890. Among them, the RF circuit 810 includes a receiver 814 and a transmitter 812. Those skilled in the art can understand that Figure 8 The mobile phone structure shown in the figure does not constitute a limitation on the mobile phone, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0308] Combine the following Figure 8 A detailed introduction to the various components of the mobile phone:

[0309] The RF circuit 810 can be used for receiving and sending signals during information transmission or calls. In particular, after receiving the downlink information of the base station, it is sent to the processor 880 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit 810 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the RF circuit 810 can also communicate with the network and other devices through wireless communication.
