Detailed Description

The following description of the technical solutions according to the embodiments of the present invention will be given with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to fall within the scope of the invention.

Some terms referred to in this application will be briefly described as follows:

research on the next generation (New radio, NR) system currently mainly considers two Frequency bands, a Frequency band FR1 (Frequency range 1) and a Frequency band FR2 (Frequency range 2), wherein 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 may be applied to FR1 and FR2 frequency bands, and may also be applied to other frequency bands, for example, a frequency band of 52.6GHz to 71GHz, or a frequency band of 71GHz to 100GHz, etc., which is not limited in this application.

Frequency band definition	Corresponding frequency range
FR1	410MHz–7.125GHz
FR2	24.25GHz–52.6GHz

TABLE 1

Studies of NR systems include non-terrestrial communication network equipment (Non Terrestrial Network, NTN) technology, where NTN typically provides communication services to terrestrial users by way of satellite communications. Satellite communications have many unique advantages over terrestrial cellular communications. First, satellite communications are not limited by the user region, for example, general land communications cannot cover areas where communication devices cannot be installed, such as oceans, mountains, deserts, etc., or communication coverage is not performed due to rarity of population, while for satellite communications, since one satellite can cover a larger ground, and the satellite can orbit around the earth, theoretically every corner on the earth can be covered by satellite communications. And secondly, satellite communication has great social value. Satellite communication can be covered in remote mountain areas, poor and backward countries or regions with lower cost, so that people in the regions enjoy advanced voice communication and mobile internet technology, and the digital gap between developed regions is reduced, and the development of the regions is promoted. Again, the satellite communication distance is far, and the cost of communication is not obviously increased when the communication distance is increased; and finally, the satellite communication has high stability and is not limited by natural disasters.

Communication satellites are classified into LEO (Low-Earth Orbit) satellites, MEO (Medium-Earth Orbit) satellites, GEO (Geostationary Earth Orbit, geosynchronous Orbit) satellites, HEO (High Elliptical Orbit ) satellites, and the like according to the difference in Orbit heights. LEO and GEO are the main studies at the present stage.

For LEO satellites, the orbital heights range from 500km to 1500km, with corresponding orbital periods of about 1.5 hours to 2 hours. The signal propagation delay for single hop communications between terminals is typically less than 20ms. The maximum satellite visibility time is 20 minutes. The signal propagation distance is short, the link loss is less, and the requirement on the transmitting power of the terminal is not high.

For GEO satellites, the orbital altitude is 35786km and the period of rotation around the earth is 24 hours. The signal propagation delay for single hop communications between users is typically 250ms.

In order to ensure the coverage of the satellite and improve the system capacity of the whole satellite communication system, the satellite adopts multiple beams to cover the ground, and one satellite can form tens or hundreds of beams to cover the ground; a satellite beam may cover a ground area of several tens to hundreds of kilometers in diameter.

Initial access in the NR system is accomplished by a synchronization signal Block (Synchronizing Signal/PBCH Block, SSB or SS/PBCH Block). SSB includes a primary synchronization signal (Primary synchronization signal, PSS), a secondary synchronization signal (Secondary synchronization signal, SSS), and a physical broadcast channel (Physical Broadcast Channel, PBCH).

Measurements in NR systems can be obtained by measuring SSB or channel state information reference signals (Channel State Information Reference Signal, CSI Reference Signal, CSI-RS).

In the NR system, the sync signal block SSB pattern supported by FR1 includes 3 cases (Case a, case B, case C), and the SSB pattern supported by FR2 includes 2 cases (Case D, case E). Wherein one SSB transmission opportunity may include one or more SSBs, one SSB includes 4 symbols in the time domain, and a group of SSB transmission opportunities should complete transmission within one half frame (5 ms). Assume that the index of the first symbol of the first slot within a field is symbol 0:

(1) Case a-15kHz subcarrier spacing:

1) The index of the first symbol of SSB includes {2,8} +14 x n;

2) For unshared spectrum:

(1) the carrier frequency is less than or equal to 3ghz, n=0, 1;

(2) the carrier frequency in FR1 is greater than 3ghz, n=0, 1,2,3;

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

(2) Case B-30kHz subcarrier spacing:

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

(1) carrier frequency is less than or equal to 3ghz, n=0;

(2) the carrier frequency in FR1 is greater than 3ghz, n=0, 1.

(3) Case C-30kHz subcarrier spacing:

1) The index of the first symbol of SSB includes {2,8} +14 x n;

2) For non-shared spectrum and belonging to paired spectrum (e.g., frequency division duplex (Frequency Division Duplex, FDD) scenarios);

(1) the carrier frequency is less than or equal to 3ghz, n=0, 1;

(2) the carrier frequency in FR1 is greater than 3ghz, n=0, 1,2,3;

3) For unshared spectrum and belonging to unpaired spectrum (e.g., time division duplex (Time Division Duplex, TDD) scenarios);

(1) the carrier frequency is less than or equal to 2.4ghz, n=0, 1;

(2) the carrier frequency in FR1 is greater than 2.4ghz, n=0, 1,2,3.

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

(4) Case D-120kHz subcarrier spacing:

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

(1) for carrier frequencies within FR2, n= 0,1,2,3,5,6,7,8,10,11,12,13,15,16,17,18.

(5) Case E-240kHz subcarrier spacing:

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

(1) for carrier frequencies within FR2, n= 0,1,2,3,5,6,7,8.

As shown in fig. 1A, a schematic diagram of a portion SSB pattern of the NR system with respect to FR1 under different conditions is shown. As shown in fig. 1B, a schematic diagram of a portion SSB pattern of the NR system with respect to FR2 under different conditions is shown. As shown in fig. 1C, a schematic diagram of a group of SSB transmission opportunities within one half frame is shown, taking SSB patterns in Case a as an example.

For downstream beam measurements, it is understood that a beam is an objectively existing physical entity and that measurement for a beam is accomplished by measuring the reference signal transmitted on that beam. The measurement metrics of the downlink beam include L1-RSRP (Reference Signal Received Power ) and/or L1-SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio), where L1 represents a layer 1 measurement, or physical layer measurement. The L1 measurement is directly processed in the physical layer, and has the advantage of less delay. Alternatively, the network device may indicate through configuration signaling that the measured RSRP metric specifically employed by the terminal device is L1-RSRP or L1-SINR. The network device may configure N reference signal resources for the terminal device, and the terminal device may report K > =1 pieces of information to the network device according to the measurement result, where each piece of information includes beam indication information (e.g. SSB index) and corresponding L1-RSRP information. Wherein the K value may be network device configured.

For a wireless mobile communication system, accurate measurement of cell quality and beam quality is the basis for effectively performing radio resource management and mobility management. The SSB may perform radio resource management (Radio Resource Management, RRM) measurements as measurement reference signals. For SSB-based measurements, the network device configures measurement configuration parameters of the SSB to the terminal device through higher layer signaling for the terminal device to perform corresponding measurement operations. The measurement configuration parameters received by the terminal device may include SSB frequency points, SSB subcarrier spacing, synchronization signal block measurement time configuration (SSB measurement timing configuration, SMTC) configuration, reference signal configuration, and other configurations, etc.

In NR, the reference signal (RLM Reference Signal, RLM-RS) for radio link monitoring (Radio Link Monitoring, RLM) is configured by higher layer signaling such as Radio Link Monitoring RS. The RLM-RS that can be configured includes: channel state information reference signals (Channel State Information Reference Signal, CSI Reference Signal, CSI-RS) and/or SSB. The configuration of one RLM-RS includes one SSB index. The network device may configure one or more RLM-RSs on each BandWidth Part (BWP) for the terminal device. The maximum number of configurable RLM-RS is related to the frequency range, e.g. 2 below 3 GHz; 4 between 3GHz and 6 GHz; 8 at 6GHz or more. The RLM-RS may also be configured for measurement purposes including RLM-RS, e.g. 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).

The beam failure recovery mechanism is supported in the NR. When the current beam transmission quality is found to be poor to a certain extent, the terminal device actively searches for a new beam with good link quality and notifies the network device, so that a high-quality reliable communication link is reestablished through the new beam. This processing is called a beam failure recovery (Beam Failure Recovery, BFR) mechanism, abbreviated as a beam recovery mechanism.

(1) Beam failure detection (Beam Failure Detection, BFD), as described above.

In NR systems, a beam failure recovery mechanism is designed for a Primary Cell (PCell) and a secondary Primary Cell (Primary Secondary Cell, PSCell). The terminal equipment measures the downlink transmission and judges the link quality corresponding to the downlink sending wave beam. If the corresponding link quality is poor, the downstream beam is considered to have failed.

(2) New beam selection (New Beam Identification, NBI)

The network device configures the terminal device with a set of reference signals (e.g., a set of SSBs) in advance. Wherein, each reference signal corresponds to an alternative downlink transmission beam, that is, the network device configures a group 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 will select a beam from the alternative beams with L1-RSRP measurement values greater than this RSRP threshold value as the new beam available.

(3) Beam failure recovery request (Beam Failure Recovery Request, BFRQ)

The terminal device needs to inform the network device of the available new beam found in order for the network device to know that it can use this new beam for downlink transmission. The use of a physical random access channel (Physical Random Access Channel, PRACH) is supported in the NR to transmit BFRQ. When the beam failure occurs, the terminal device triggers the random access flow, and the MSG1 of the random access indicates the network side that the terminal device has the beam failure and the new beam information selected by the terminal device.

(4) Network side response

If the BFR triggers non-contention random access, the UE monitors the random access response using a new beam in the search space exclusive to the BFR, that is, the network device configures the core corresponding to the BFR and the search space in advance, and the dedicated core is associated with only the dedicated search space and not associated with other search spaces. If the terminal device monitors the downlink control information (Downlink Control Information, DCI) sent to it by the network device on the new beam within the random access response window, the beam recovery is considered successful.

In the NTN scenario shown in the embodiment of the present application, one satellite may serve multiple root print through multiple beams, where one root print may be considered as one coverage area of the ground, and may be referred to as a coverage cell. Wherein the plurality of root print correspond to the same cell Identity (ID) or to the same satellite cell. Fig. 2A is a schematic diagram of an NTN scenario according to an embodiment of the present invention.

One root print may correspond to one or more beams. Specifically, taking one slot print corresponding to one beam as an example, 3 cases may be included in the NTN network deployment scenario based on the beam:

Case 1: the Frequency reuse factor (Frequency re-use factor) is 1, as shown in fig. 2B, which is a schematic diagram of the Frequency reuse factor 1 in the NTN scenario.

Case 2: the Frequency reuse factor (Frequency re-use factor) is 3, as shown in fig. 2C, which is a schematic diagram of the Frequency reuse factor of 3 in the NTN scenario.

Case 3: the Frequency reuse factor (Frequency re-use factor) is 2, as shown in fig. 2D, which is a schematic diagram of the Frequency reuse factor of 2 in the NTN scenario.

In NTN systems, when a network device (e.g., a satellite) serves multiple terrestrial coverage cells (identities) through multiple beams, the multiple identities may correspond to the same cell Identity (ID). In addition, under the condition that the frequency multiplexing factor is greater than 1, different boot print can correspond to different frequency resources. In these scenarios, it is currently 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 configuration information of the measurement resources issued by the network device.

Fig. 3A is an architecture schematic diagram of a communication system according to an embodiment of the present application. As shown in fig. 3A, the communication system 100 may include a network device 110, and the network device 110 may be a device that communicates with a terminal device 120 (or referred to as a communication terminal, terminal). Network device 110 may provide communication coverage for a particular geographic area and may communicate with terminal devices located within the coverage area.

In the architecture of the communication system shown in FIG. 3B, satellite 1102 may have the functionality of a base station and direct communication may be provided between terminal device 1101 and satellite 1102. Under the system architecture, satellite 1102 may be referred to as a network device. Alternatively, a plurality of network devices 1102 may be included in the communication system, and other numbers of terminal devices may be included within the coverage area of each network device 1102, which is not limited in this embodiment of the present application.

The network formed between the terminal device 1201, the satellite 1202 and the base station 1203 may also be referred to as NTN. In the architecture of the communication system shown in fig. 3C, the satellite 1202 may not have the function of a base station, and communication between the terminal device 1201 and the base station 1203 needs to pass through the transit of the satellite 1202. Under such a system architecture, the base station 1203 may be referred to as a network device. Alternatively, a plurality of network devices 1203 may be included in the communication system, and the coverage area of each network device 1203 may include other number of terminal devices, which is not limited in the embodiment of the present application.

Taking the example that each segment of frequency resource in case 2 corresponds to one BWP for example, one coverage cell corresponds to one BWP, and different SSB indexes can be corresponding to different BWP in the NTN network. Fig. 4A is an exemplary diagram of a beam-based NTN networking scenario according to an embodiment of the present invention.

Fig. 4B-4E are exemplary diagrams illustrating several ways in which a network device may transmit SSBs within an SMTC window in an embodiment of the present invention, and a terminal device may perform corresponding measurements according to SSBs transmitted by the network device within the SMTC window. It should be understood that this SSB transmission manner is merely an example, and the embodiments of the present application may also be applied to other scenarios of SSB transmission, which is not limited in this application. In these examples, it is assumed that the number of SSBs that the network device needs to send is 3, i.e. a set of SSB transmissions within the SMTC window includes 3 SSBs, where different BWP corresponds to different beams for transmitting different or identical SSB indexes, BWP identification and SSB index may be in one-to-one or one-to-many relation, as shown in fig. 4A, where the corresponding beam in BWP0 is SSB0, the corresponding beam in BWP1 is SSB1, and the corresponding beam in BWP2 is SSB2. Several ways of SSB transmission by the network device are described below, respectively, as follows:

mode 1: referring to fig. 4B, SSBs are transmitted on respective corresponding BWPs according to the association relationship of SSB indexes and BWP identification. I.e. SSB0 is sent over BWP0, SSB1 is sent over BWP1, and SSB2 is sent over BWP 2. The SSB may be cell-defining SSB or non-cell defining SSB.

Mode 2: referring to fig. 4c, the SSB transmission method is different from Rel-15 in that, assuming BWP0 is an initial BWP in a cell, the set of SSBs is transmitted through BWP0 and the set of SSBs is a cell-defining SSB. In addition, BWP1 and BWP2 are also transmitted with part of SSBs in the set of SSBs, and the BWP1 or BWP2 has an association relationship with part of SSBs in the set of SSBs transmitted on BWP 0. I.e. SSB1 is also sent over BWP1 and SSB2 is also sent over BWP 2. Wherein the SSB transmitted on BWP1 and BWP2 is a non-cell defining SSB. Optionally, SSBs transmitted on BWP1 and BWP2 also need to be sent on the synchronization grid.

Mode 3: referring to fig. 4d, the SSB transmission method is similar to Rel-15, assuming BWP0 is an initial BWP in a cell, the set of SSBs is transmitted through BWP0, and the set of SSBs is a cell-defined SSB. In addition, the set of SSB transmissions is also on BWP1 and BWP2, and the SSB transmitted on BWP1 and BWP2 is a non-cell defining SSB. Optionally, SSBs transmitted on BWP1 and BWP2 also need to be sent on the synchronization grid.

Mode 4: referring to fig. 4e, the SSB transmission method is the same as Rel-15, and assuming BWP0 is an initial BWP in a cell, the set of SSBs is transmitted through BWP0 and the set of SSBs is cell-defined SSBs. There may be no SSB transmission on BWP1 and/or BWP 2.

Taking reference signal resources as SSB resources as examples, the technical scheme of the present invention is described separately from SSB-based downlink beam measurement, SSB-based mobility measurement, SSB-based RLM measurement, and SSB-based beam failure recovery mechanism, where measurement of other reference signal resources may refer to SSB resources, and will not be described in detail. The following is shown:

1. downstream beam measurement based on SSB

For example: the measurement metrics of the downlink beams may include L1-RSRP (Reference Signal Received Power ), and/or L1-SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio), where L1 represents a measurement of layer 1, or physical layer measurement. The L1 measurement can be processed directly at the physical layer, which has the advantage of less delay. Alternatively, the network device may indicate, through configuration signaling, i.e. the first configuration information described above, that the measurement metric specifically adopted by the terminal device is L1-RSRP or L1-SINR.

The terminal equipment reports K more than or equal to 1 report information to the network equipment, wherein each report information comprises a measurement result; the report information may also include beam indication information (e.g., SSB index), and corresponding L1-RSRP information; the reported information may also include a frequency domain location corresponding to the SSB and/or a coverage cell corresponding to the SSB. And when K is more than 1, the quantization result of the maximum value in the K L1-RSRP values is directly reported, and the difference value between the other K1L 1-RSRP values and the maximum L1-RSRP value is reported after quantization, namely the difference value is reported by the other K1L 1-RSRP values. The measurement of the L1-SINR is similarly reported, and is not repeated here.

Optionally, according to whether the terminal device can receive data transmitted simultaneously on K downlink beams, the reporting methods of the measurement results may be classified into the following two types: non-group-based reporting (Non-group based reporting) and group-based reporting (Group based reporting).

In the non-group-based reporting, the terminal device performs measurement according to N reference signal resources configured by the network device, where the N reference signal resources are configured in M BWP, 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 pieces of reporting information are selected to be reported, and the value of K is configured by the network equipment and can be 1, 2, 3 or 4. The K reference signal resources correspond to K beams. The network device cannot transmit signals from multiple ones of the K beams simultaneously to the terminal device because the terminal device cannot receive signals transmitted on multiple downlink beams simultaneously.

For example, for a terminal device located in a coverage cell of FP14, BWP2, B2, the reference signal resources configured by the network device for the terminal device for downlink beam 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, SSB1 corresponding to FP10 and BWP1, so that the terminal device can switch to an appropriate BWP or beam in time for transmission if in the course of moving.

When the terminal equipment reports K pieces of reporting information, the terminal equipment selects reporting beams according to M configured BWPs:

optionally, if K is less than or equal to M, the terminal device selects one beam (or SSB) with the strongest L1-RSRP from each of K BWP among the M BWP, where the K BWP is the K strongest L1-RSRP among the M BWP.

Alternatively, if K is greater than M, the terminal device selects one of the strongest L1-RSRP beams (or SSBs) from each of the M BWP's. For the remaining (K-M) beams, the terminal device may select itself according to its implementation algorithm, for example, only the K strongest L1-RSRP beams may be considered, or the remaining (K-M) beams may be selected in consideration of the directions of arrival of different beams (i.e., in consideration of spatial correlation between different received reference signals).

2. SSB-based mobility measurement

For mobility measurement based on SSB, the network device configures the first configuration information of SSB to the terminal device through higher layer signaling, so that the terminal device performs a corresponding measurement operation. The first configuration information received by the terminal device may include SSB frequency points, SSB subcarrier spacing, synchronization signal block measurement time configuration (SSB measurement timing configuration, SMTC), reference signal configuration, and other configurations, etc. The first configuration information may further include a frequency domain location corresponding to the SSB, and/or other configuration information such as a coverage cell corresponding to the SSB.

The SSB frequency point is the center frequency point position of the SSB to be measured. The SSB subcarrier spacing is subcarrier spacing information of SSB to be measured, and may be 15kHz or 30kHz, for example. SMTC is time domain resource configuration information of SSB measurements, which is mainly used to configure a set of measurement time windows based on SSB measurements, and the size, position, period, etc. of the windows can be adjusted by configuration parameters. At most two sets of SMTC parameters can be configured for measurement. The configuration information (e.g., reference Signal Config) of the first reference signal resource is used to indicate specific configuration information of a particular measurement reference signal resource. For SSB-based measurements, the configuration information of the first reference signal resource includes SSB configuration parameters, such as SSB indication (e.g., SSB-To measurement) information To be measured.

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

For example, assuming that the corresponding bit bitmap in the SSB to be measured indication includes [10000000] associated with BWP0, [01000000] associated with BWP1, [00100000] associated with BWP2, then the SSB within the SMTC window that the terminal device should measure is described as including: SSB0 on BWP0, SSB15 on BWP1, SSB2 on BWP 2. Accordingly, the terminal device may perform mobility management measurements according to the first configuration information.

3. SSB-based radio link monitoring (Radio Link Monitoring, RLM) measurements

A configuration of a radio link monitoring (Radio Link Monitoring, RLM) reference signal (RLM Reference Signal, RLM-RS) includes an index of an SSB, and may also include a frequency domain location corresponding to the SSB, and/or a coverage cell corresponding to the SSB. The network device may configure one or more RLM-RSs on each BWP for the terminal device. The network device may also configure the terminal device with other configuration information such as BWP or coverage cells to be RLM measured.

For example, for a terminal device located in a coverage cell of FP14, BWP2, B2, the reference signal resources configured by the network device for the terminal device for 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, SSB1 corresponding to FP10 and BWP1, so that the terminal device can switch to an appropriate BWP or beam in time for transmission if in the course of moving.

The RLM-RS may also be configured for measurement purposes including RLM-RS, for example, 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).

(1) Cell failure detection (Radio Link Failure Detection)

The measure of cell failure detection is the block error rate (BLER) of the Hypothetical (downlink) physical downlink control channel (Physical Downlink Control Channel, PDCCH). Since the true BLER of the PDCCH transmission is not directly available, the terminal device derives the corresponding possible BLER from the measured SINR, and is therefore referred to as the hypothesized PDCCH BLER. Among the configured RLM-RSs, the UE assumes that the RLM-RS has the same antenna port as the estimated assumed PDCCH.

The NR system supports two sets of hypothesized BLER for PDCCH. Wherein the first set of thresholds IS consistent with long term evolution technology (Long Term Evolution, LTE), and the assumed PDCCH BLER corresponding to the threshold of synchronization (In Synchronization, IS) IS 2%; the threshold for out-of-step (Out Of Synchronization, OSS) corresponds to an assumed PDCCH BLER of 10%. The purpose of introducing another set of thresholds is that the set of thresholds corresponds to a higher assumed PDCCH BLER, so that the connection of the radio link can be maintained at a position with poor radio signal, and the connection failure caused by triggering the radio link failure is avoided, thereby being beneficial to maintaining the continuity of services such as voice over IP (Voice over Internet Protocol, voIP) and the like. Which set of hypothesized PDCCH BLER thresholds to use may be configured by the network device.

If the terminal device is configured with a BWP or a coverage cell to be subjected to RLM measurement, the terminal device performs RLM measurement on the BWP determined according to the configuration information using the RLM-RS configured on the BWP; or when no RLM-RS is configured on the BWP determined according to the configuration information, using CSI-RS corresponding to an activated TCI state corresponding to a Control-resource set (CORESET) for PDCCH reception on the BWP determined according to the configuration information as RLM-RS to perform RLM measurement. Wherein the terminal device may be configured with one or more BWP or overlay cells to make RLM measurements.

After the RLM-RS IS configured, the terminal device performs measurement according to the configured RLM-RS, and the measurement result IS compared with a threshold value of synchronization (In Synchronization, IS)/out-of-sync (Out Of Synchronization, OSS), so as to obtain an IS/OOS state of the wireless link, and periodically report an evaluation result of the IS/OOS state to a higher layer or network device of the terminal device. When reporting the evaluation result, it is also necessary to report corresponding BWP information such as BWP ID or overlay cell information such as overlay cell ID. For each BWP or each coverage cell, if the measurement result of at least one RLM-RS in all configured RLM-RSs IS higher than an IS threshold, the physical layer reports the IS state of the BWP or the coverage cell to a higher layer or network device; alternatively, if the measurement results of all RLM-RS configured are below the OOS threshold, the physical layer reports the OOS status of the BWP or overlay cell to higher layers or network devices.

Illustratively, in the non-DRX state, the reporting period of the IS/OOS state IS a maximum between a shortest period and 10ms of periods of all RLM-RS resources configured. In the DRX state, the reporting period of the IS/OOS state IS the maximum value between the shortest period and the DRX period of all the configured RLM-RS resource periods.

(2) Beam failure detection (Beam Failure Detection, BFD)

The measure of beam failure detection is the assumed PDCCH BLER. The physical layer detects the hypothetical BLER of the PDCCH corresponding to the beam, and if the hypothetical PDCCH BLER of all beams is worse than a specified threshold, it is noted as a beam failure sample (Beam Failure Instance, BFI), and the medium access control layer (Medium Access Control, MAC) is reported that BFI occurs once. Alternatively, if the terminal device measures that the quality of the other beams configured is higher than a specified threshold or that the quality of the other beams configured 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 timely determine whether the coverage cell change occurs in the terminal device, so as to perform timely beam switching.

For example, for a terminal device located in a coverage cell of FP14, BWP2, B2, the reference signal resources configured by the network device for the terminal device for measurement 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 report an appropriate BWP or beam to the network device in time if in the moving process.

The physical layer may periodically report to the MAC side and consider no BFI if there is no report at a time. The MAC layer maintains an associated beam failure detection timer (beam Failure Detection Timer) and beam failure COUNTER (bfi_counter). In order to ensure the reliability of beam failure detection, the MAC layer starts or restarts a beam failure detection timer every time it receives a BFI report, and the beam failure counter is increased by 1, if the beam failure detection timer is overtime, the terminal resets the counter to 0, thereby ensuring that the judgment of beam failure is based on continuous BFI report. If the beam failure counter reaches a prescribed maximum value during the timer running, the terminal device considers that beam failure has occurred.

4. SSB-based beam failure recovery mechanism

The terminal equipment measures the downlink transmission and judges the link quality corresponding to the downlink sending wave beam. If the corresponding link quality is poor, the downstream beam is considered to have failed. The terminal device may also measure a set of alternative beams, from which a beam satisfying a certain threshold is selected as a new beam. The terminal device then informs the network device that a beam failure occurred and reports a new beam through a beam failure recovery request (Beam Failure Recovery Request, BFRQ) procedure. After receiving BFRQ information sent by a terminal device, a network device knows that the terminal device has failed in a beam, selects to send PDCCH from a new beam, and the terminal device considers that response information of a network side is correctly received after receiving the PDCCH sent by the network device on the new beam. So far, the beam failure recovery flow is successfully completed. Its main functional modules (or called main steps) are divided into 4:

(1) Beam failure detection (Beam Failure Detection, BFD) is as described above and will not be described in detail here.

(2) New beam selection (New Beam Identification, NBI)

The network device configures the terminal device with a set of reference signals (e.g., a set of SSBs) in advance, and a BWP or coverage cell corresponding to each reference signal. Wherein each reference signal and the corresponding BWP or coverage cell corresponds to an alternative downlink transmission beam, i.e. the network device configures the terminal device with a set of alternative downlink transmission beams. 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 will select a beam from the alternative beams with L1-RSRP measurement values greater than this RSRP threshold value as the new beam available.

(3) Beam failure recovery request (Beam Failure Recovery Request, BFRQ)

The terminal device needs to inform the network device of the available new beam found in order for the network device to know that it can use this new beam for downlink transmission.

The use of a physical random access channel (Physical Random Access Channel, PRACH) is supported in the NR to transmit BFRQ. When the beam failure occurs, the terminal device triggers the random access flow, and the MSG1 of the random access indicates the network side that the terminal device has the beam failure and the new beam information selected by the terminal device.

In case of pre-configuring dedicated PRACH resources for BFRQ based on the network device, the random access type is non-contention random access. The network device pre-configures a set of candidate beams (e.g. SSBs) and corresponding BWP or coverage cells for the terminal device, and configures a corresponding PRACH resource and random preamble for each SSB therein (wherein each SSB configuration corresponds to one BWP or one coverage cell), then when the terminal device determines that a certain beam is a new beam, the network device sends a corresponding random preamble using the PRACH resource corresponding to the new beam, upon receipt by the network device, knows that a beam failure occurred for the terminal device, the network device determines a new beam selected by the terminal device based on the received PRACH information, and sends a random access response on the new beam.

In the case that 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 find available new beams among the candidate beams configured by the network device (e.g., the network device does not configure reference signals for NBI and corresponding PRACH resources, i.e., the terminal device does not have candidate beams that can be measured, or L1-RSRP measurement values corresponding to all candidate beams are worse than a threshold value configured by the network), the terminal device initiates an existing contention-based random access procedure to complete reconnection with the network device according to SSB signal quality measurement results in the cell. In this case, since the network device does not pre-configure the dedicated PRACH resource for the beam failure request for the terminal device, after the terminal device transmits the corresponding Msg1, the network device does not know whether the terminal device is a random access procedure initiated due to beam failure or a random access procedure initiated for other reasons. In the NR enhanced version R16, to further enhance the beam failure recovery mechanism in this case, the terminal device may carry a MAC CE dedicated to indicating BFR information in Msg3 or MsgA of contention-based random access to indicate to the network device that the random access procedure is triggered due to beam failure, and the BFR MAC Control unit (CE) may also carry new beam information selected by the terminal device, BWP information corresponding to the new beam information, and/or coverage cell information.

(4) Network side response

If the BFR triggers non-contention random access, the UE monitors the random access response using the new beam on the search space dedicated to the BFR on the corresponding BWP, that is, the network device configures the CORESET and the search space on the BWP corresponding to the BFR in advance, and the dedicated CORESET is associated with only the dedicated search space and not other search spaces. If the terminal device monitors the downlink control information (Downlink Control Information, DCI) issued to it by the network device on the new beam on the corresponding BWP within the random access response window, beam recovery is considered successful.

For the case that the network device is not configured with BFR dedicated resources, that is, the contention-based random access mentioned above, the network device does not need to configure this dedicated search space, and the UE monitors the PDCCH in the common search space.

The terminal equipment can measure according to the measurement resource configuration information issued by the network equipment to obtain a measurement result, further enhances the existing measurement scheme and improves the measurement in the NTN system.
