detailed description

The technical solutions in the embodiments of the present invention will be described below with reference to the 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.

The following is a brief description of some terms involved in this application, as follows:

The research on the next generation (New Radio, NR) system currently mainly considers two frequency bands, the frequency band FR1 (Frequency range 1) and the frequency band FR2 (Frequency range 2). Among them, FR1 and FR2 include the frequency domain range As 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, such as a frequency band of 52.6 GHz to 71 GHz, or a frequency band of 71 GHz to 100 GHz, which is not limited in this application.

FR2FR2	24.25GHz–52.6GHz24.25GHz–52.6GHz

Table 1

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

Communication satellites are classified into LEO (Low-Earth Orbit, low earth orbit) satellites, MEO (Medium-Earth Orbit, medium earth orbit) satellites, GEO (Geostationary Earth Orbit, geosynchronous orbit) satellites, HEO (High Earth orbit) satellites according to the different orbital altitudes. Elliptical Orbit, high elliptical orbit) satellites, etc. The main research at this stage is LEO and GEO.

For LEO satellites, the orbital altitude ranges from 500km to 1500km, 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 20ms. The maximum satellite viewing time is 20 minutes. The signal propagation distance is short, the link loss is low, and the transmit power requirements of the terminal are not high.

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

In order to ensure the coverage of satellites and improve the system capacity of the entire satellite communication system, satellites use multiple beams to cover the ground. A satellite can form tens or even hundreds of beams to cover the ground; a satellite beam can cover tens to hundreds of kilometers in diameter ground area.

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

The measurement in the NR system can be obtained by measuring the SSB or the channel state information reference signal (Channel State Information Reference Signal, CSI Reference Signal, CSI-RS).

In the NR system, the synchronization 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). 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 (5ms). Suppose the index of the first symbol of the first slot in a field is symbol 0:

(1) Case A-15kHz subcarrier spacing:

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

2) For non-shared spectrum:

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

②The 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;

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

②The carrier frequency in FR1 is greater than 3GHz, and n=0,1.

(3) Case C-30kHz subcarrier spacing:

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

2) For non-shared spectrum and belong to paired spectrum (for example, frequency division duplex (Frequency Division Duplex, FDD) scenario);

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

②The carrier frequency in FR1 is greater than 3GHz, n=0,1,2,3;

3) For non-shared spectrum and belong to non-paired spectrum (for example, Time Division Duplex (TDD) scenario);

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

②The carrier frequency in FR1 is greater than 2.4GHz, and 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;

①For the carrier frequency in 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 the SSB includes {8, 12, 16, 20, 32, 36, 40, 44}+56*n;

①For the carrier frequency in FR2, n=0,1,2,3,5,6,7,8.

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

For downlink beam measurement, it should be understood that the beam is an objectively existing physical entity, and the measurement of a beam is achieved by measuring the reference signal transmitted on the beam. The measurement metrics of the downlink beam include L1-RSRP (Reference Signal Received Power, reference signal received power) and/or L1-SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio), where L1 represents the measurement of layer 1, Or physical layer measurements. L1 measurements are processed directly at the physical layer, with the advantage of less delay. Optionally, the network device may instruct the terminal device to use the configuration signaling to measure the RSRP metric specifically to be L1-RSRP or L1-SINR. The network device may configure N reference signal resources for the terminal device, and the terminal device reports K>=1 pieces of information to the network device according to the measurement result, each information including beam indication information (eg SSB index) and corresponding L1-RSRP information . The K value may be configured by the network device.

For wireless mobile communication systems, accurate measurement of cell quality and beam quality is the basis for effective wireless resource management and mobility management. The SSB can be used as a measurement reference signal to perform radio resource management (Radio Resource Management, RRM) measurement. For SSB-based measurement, the network device configures the SSB measurement configuration parameters to the terminal device through high-layer signaling, so that the terminal device can 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 timing configuration (SSB measurement timing configuration, SMTC) configuration, reference signal configuration, and other configurations.

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

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

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

In the NR system, a beam failure recovery mechanism is designed for the primary cell (Primary Cell, PCell) and the primary secondary cell (Primary Secondary Cell, PSCell). The terminal device measures the downlink transmission and determines 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 failed to generate beam.

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

The network device configures a set of reference signals (eg, a set of SSBs) for the terminal device in advance. Wherein, each reference signal corresponds to one 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, and the terminal device selects a beam as an available new beam from the candidate beams whose L1-RSRP measurement value is greater than the RSRP threshold.

(3) Beam Failure Recovery Request (BFRQ)

The terminal device needs to notify the network device of the available new beam found, so that the network device knows that the new beam can be used for downlink transmission. The use of Physical Random Access Channel (PRACH) to transmit BFRQ is supported in NR. That is, when a beam failure occurs, the terminal device will trigger the random access procedure, and the MSG1 of the random access indicates that the terminal device has a beam failure on the network side and the new beam information selected by the terminal device.

(4) Network side response

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

In the NTN scenario shown in the embodiment of the present application, one satellite can serve multiple footprints through multiple beams, and one footprint can be considered as a coverage area on the ground, which can be called a coverage cell. The multiple footprints correspond to the same cell identity (Identity, ID) or correspond to the same satellite cell. As shown in FIG. 2A , it is a schematic diagram of an NTN scenario to which an embodiment of the present invention is applied.

A footprint can correspond to one or more beams. Specifically, taking one footprint corresponding to one beam as an example, there are three situations in the beam-based NTN network deployment scenario:

Case 1: the frequency re-use factor is 1, as shown in FIG. 2B , which is a schematic diagram of the frequency re-use factor being 1 in the NTN scene.

Case 2: the frequency re-use factor is 3, as shown in FIG. 2C , which is a schematic diagram of the frequency re-use factor being 3 in the NTN scene.

Case 3: The frequency re-use factor is 2, as shown in FIG. 2D , which is a schematic diagram of the frequency re-use factor being 2 in the NTN scene.

In the NTN system, when a network device (such as a satellite) serves multiple coverage cells (footprints) on the ground through multiple beams, the multiple footprints may correspond to the same cell identity (Identity, ID). In addition, when the frequency reuse factor is greater than 1, different footprints can correspond to different frequency resources. In these scenarios, it is currently unclear how the network device configures measurement resources for the terminal device, and how the terminal device performs downlink beam measurement, RRM measurement, RLM measurement, or BFR based on the configuration information of the measurement resources delivered by the network device.

In the architecture of the communication system shown in FIG. 3C , the satellite 1202 may not have the function of the base station, and the communication between the terminal device 1201 and the base station 1203 needs to be relayed through the satellite 1202 .

Taking the reference signal resource as an SSB resource as an example, the technical solutions of the present invention will be described separately from the SSB-based downlink beam measurement, SSB-based mobility measurement, SSB-based RLM measurement, and SSB-based beam failure recovery mechanism. For measurement of reference signal resources, etc., reference may be made to SSB resources, and details are not repeated here. As follows:

1. Downlink beam measurement based on SSB

For example, the measurement metric of the downlink beam may include L1-RSRP (Reference Signal Received Power, reference signal received power), and/or L1-SINR (Signal to Interference plus Noise Ratio, signal to interference plus noise ratio), where L1 represents Layer 1 measurements, or, say, physical layer measurements. L1 measurements can be processed directly at the physical layer, with the advantage of less delay. Optionally, the network device may indicate that the measurement metric specifically adopted by the terminal device is L1-RSRP or L1-SINR through configuration signaling, that is, the above-mentioned first configuration information.

The terminal device reports K ≥ 1 report information to the network device, and each report information includes a measurement result; the report information may also include beam indication information (such as SSB index), and corresponding L1-RSRP information; the report information may also include The frequency domain location corresponding to the SSB, and/or the coverage cell corresponding to the SSB. When K>1, the quantization result of the maximum value of the K L1-RSRP values is directly reported, and the difference between the other K-1 L1-RSRP values and the maximum L1-RSRP value is quantized and reported, that is, the other K-1 Each L1-RSRP reports the differential value. The measurement of L1-SINR is also reported similarly, and details are not repeated here.

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

In 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 BWPs, and each BWP includes one or more reference signal resources , N is greater than or equal to M. According to the measurement result, K pieces of report information are selected to be reported. The value of K is configured by the network device and can be 1, 2, 3, or 4. K reference signal resources correspond to K beams. The network device cannot simultaneously transmit signals to the terminal device from multiple beams in the K beams, because the terminal device cannot simultaneously receive signals transmitted on multiple downlink beams.

Exemplarily, for a terminal device located in the coverage cells of FP14, BWP2, and B2, the reference signal resources for downlink beam measurement configured by the network device for the terminal device include one or more of the following: SSB0 corresponding to FP0 and BWP0 , corresponding to SSB1 of FP13 and BWP1, corresponding to SSB0 of FP12 and BWP0, corresponding to SSB1 of FP22 and BWP1, corresponding to SSB0 of FP9 and BWP0, corresponding to SSB1 of FP10 and BWP1, so that the terminal equipment can switch to the appropriate BWP or beam for transmission.

When reporting K pieces of reporting information, the terminal device selects the reporting beam according to the configured M BWPs:

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

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 (KM) beams, the terminal device can choose according to its own implementation algorithm. For example, it can only consider the K with the strongest L1-RSRP, or consider the arrival directions of different beams (that is, consider the different received reference signals. spatial correlation) to select the remaining (KM) beams.

2. Mobility measurement based on SSB

For SSB-based mobility measurement, the network device configures the first configuration information of the SSB to the terminal device through high-layer signaling, so that the terminal device can perform 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 timing configuration (SSB measurement timing configuration, SMTC), reference signal configuration, and other configurations. 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 position of the center frequency point of the SSB to be measured. The SSB subcarrier spacing is the subcarrier spacing information of the SSB to be measured, for example, it may be 15 kHz or 30 kHz. SMTC is time-domain resource configuration information for SSB measurement, which is mainly used to configure a set of measurement time windows based on SSB measurement, and parameters such as the size, location, and period 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 (for example, Reference Signal Config) is used to indicate the specific configuration information of the specific measurement reference signal resource. For SSB-based measurement, the configuration information of the first reference signal resource includes SSB configuration parameters, such as SSB to be measured indication (eg SSB-To Measure) information.

The indication information of the SSB to be measured uses a bitmap to indicate the location information of the SSB to be measured in the SSB burst set, 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, a row of bitmaps corresponds to a frequency domain location or a coverage cell, the first bit (or the leftmost bit) in a row of bitmaps corresponds to SSB index 0, the second bit corresponds to SSB index 1, and 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 the SSB indication to be measured, it means that all SSBs in the SMTC window need to be measured.

For example, assuming that the corresponding bitmap in the indication of the SSB to be measured includes [10000000] associated with BWP0, [01000000] associated with BWP1, and [00100000] associated with BWP2, then the SSBs in the SMTC window that should be measured by the terminal device include: SSB0 on BWP0, SSB15 on BWP1, SSB2 on BWP2. Correspondingly, the terminal device may perform mobility management measurement according to the first configuration information.

3. Measurement of Radio Link Monitoring (RLM) based on SSB

The 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 position corresponding to the SSB, and/or, the corresponding SSB coverage area. 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 the BWP or the coverage cell to be performed RLM measurement.

Exemplarily, for a terminal device located in the coverage cells of FP14, BWP2, and B2, the reference signal resources for RLM measurement configured by the network device for the terminal device include one or more of the following: SSB0 corresponding to FP0 and BWP0, Corresponding to SSB1 of FP13 and BWP1, corresponding to SSB0 of FP12 and BWP0, corresponding to SSB1 of FP22 and BWP1, corresponding to SSB0 of FP9 and BWP0, corresponding to SSB1 of FP10 and BWP1, so that the terminal equipment can switch to the appropriate BWP or beam for transmission.

The configuration of the RLM-RS may also include the measurement purpose of the RLM-RS, for example, it can be used for beam failure detection (for example, configured as beam failure), or for cell failure detection (for example, configured as rlf), or, both for Beam failure detection is also used for cell failure detection (eg, configured as both).

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

The metric for cell failure detection is a hypothetical (Hypothetical) physical downlink control channel (Physical Downlink Control Channel, PDCCH) block error rate (block error rate, BLER). Because the real BLER transmitted by the PDCCH cannot be directly obtained, the terminal device calculates the corresponding possible BLER according to the measured SINR, so it is called the assumed PDCCH BLER. Among the configured multiple 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 assumed PDCCH BLERs. Among them, the first set of thresholds is consistent with Long Term Evolution (LTE), the assumed PDCCH BLER corresponding to the threshold of In Synchronization (IS) is 2%; the threshold of Out Of Synchronization (OSS) corresponds to The assumed PDCCH BLER is 10%. The purpose of introducing another set of thresholds is that this set of thresholds corresponds to a higher assumed PDCCH BLER, so that the connection of the wireless link can be maintained even in the position where the wireless signal is poor, so as to avoid the failure of the connection caused by triggering the failure of the wireless link. It is beneficial to maintain the continuity of services such as IP-based voice transmission (Voice over Internet Protocol, VoIP). Which set of assumed PDCCH BLER thresholds to use is configurable by the network device.

If the terminal device is configured with a BWP or coverage cell for which RLM measurement is to be performed, the terminal device performs RLM measurement on the BWP determined according to the configuration information using the RLM-RS configured on the BWP; or there is no BWP determined according to the configuration information. When configuring the RLM-RS, use the CSI-RS corresponding to the activated TCI state corresponding to the control resource set (Control-resource set, CORESET) on the BWP determined according to the configuration information for PDCCH reception, as the RLM-RS for RLM Measurement. The terminal equipment may be configured with one or more BWPs or coverage cells to perform RLM measurements.

After the RLM-RS is configured, the terminal device measures according to the configured RLM-RS, and the measurement result is compared with the In Synchronization (IS)/Out Of Synchronization (OSS) threshold to obtain the wireless link the IS/OOS status, and periodically report the IS/OOS status evaluation result to the upper layer of the terminal device or the network device. When reporting the evaluation result, it is also necessary to report the corresponding BWP information such as the BWP ID or coverage cell information such as the coverage 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 the IS threshold, the physical layer reports the IS status of the BWP or the coverage cell to the upper layer or the network device; Alternatively, if the measurement results of all the configured RLM-RSs are lower than the OOS threshold, the physical layer reports the OOS state of the BWP or the coverage cell to the upper layer or the network device.

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

(2) Beam Failure Detection (BFD)

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 sample (Beam Failure Instance, BFI), which is sent to the medium access control layer (Medium Access Control, MAC) reports that a BFI occurs. Or, if the terminal device measures that the quality of the configured other beams is higher than a specified threshold or the quality of the configured other 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 real beam failure, but a beam failure recovery mechanism is used to timely determine whether the terminal equipment has changed the coverage cell, so as to perform timely beam switching.

Exemplarily, for a terminal device located in the coverage cells 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, corresponding to SSB1 of FP13 and BWP1, corresponding to SSB0 of FP12 and BWP0, corresponding to SSB1 of FP22 and BWP1, corresponding to SSB0 of FP9 and BWP0, corresponding to SSB1 of FP10 and BWP1, so that the terminal device can report the appropriate BWP or beam.

The physical layer can periodically report to the MAC side. If there is no report for 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, whenever the MAC layer receives a BFI report, it starts or restarts the beam failure detection timer, and the count of the beam failure counter increases by 1. If the beam failure detection timer expires, the terminal resets the counter. It is 0 to ensure that the judgment of beam failure is based on continuous BFI reporting. If the beam failure counter reaches the specified maximum value within the running period of the timer, the terminal device considers that a beam failure has occurred.

4. SSB-based beam failure recovery mechanism

The terminal device measures the downlink transmission and determines 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 failed to generate beam. The terminal device also measures a set of candidate beams, and selects a beam that meets a certain threshold as a new beam. Then, the terminal device notifies the network device that a beam failure has occurred through the beam failure recovery request (Beam Failure Recovery Request, BFRQ) process, and reports a new beam. After the network device receives the BFRQ information sent by the terminal device, it knows that the terminal device has a beam failure, and chooses to send the PDCCH on the new beam. The terminal device receives the PDCCH sent by the network device on the new beam, and it considers that the response from the network side has been correctly received. information. So far, the beam failure recovery process is successfully completed. Its main function modules (or main steps) are divided into 4 parts:

(1) Beam Failure Detection (BFD) is as described above, and will not be repeated here.

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

The network device configures the terminal device in advance with a set of reference signals (eg, a set of SSBs) and a BWP or coverage cell corresponding to each reference signal. Wherein, each reference signal and the corresponding BWP or coverage cell correspond to one 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, and the terminal device selects a beam as an available new beam from the candidate beams whose L1-RSRP measurement value is greater than the RSRP threshold.

(3) Beam Failure Recovery Request (BFRQ)

The terminal device needs to notify the network device of the available new beam found, so that the network device knows that the new beam can be used for downlink transmission.

The use of Physical Random Access Channel (PRACH) to transmit BFRQ is supported in NR. That is, when a beam failure occurs, the terminal device will trigger the random access procedure, and the MSG1 of the random access indicates that the terminal device has a beam failure on the network side and the new beam information selected by the terminal device.

In the case of pre-configuring dedicated PRACH resources for BFRQ based on network equipment, the random access type is non-contention random access. The network device pre-configures a set of candidate beams (such as SSBs) and corresponding BWPs or coverage cells for the terminal device, and configures the corresponding PRACH resources for each SSB (wherein, each SSB configuration corresponds to one BWP or one coverage cell) and Random preamble, then when the terminal device determines that a certain beam is a new beam, it uses the PRACH resource corresponding to the new beam to send the corresponding random preamble. After the network device receives it, it knows that a beam failure has occurred in the terminal device. The received PRACH information determines the new beam selected by the terminal device and sends a random access response on the new beam.

When the network device may not configure dedicated BFR resources (including a set of candidate beams and their corresponding dedicated PARCH resources) to the terminal device, or the terminal device may not be able to find available new beams in the candidate beams configured by the network device (for example, the network device When the reference signal and corresponding PRACH resources for NBI are not configured, that is, the terminal device has no candidate beams to measure, or the L1-RSRP measurement values corresponding to all candidate beams are worse than the threshold value configured by the network), the terminal The device will initiate the existing contention-based random access procedure to complete the reconnection with the network device according to the SSB signal quality measurement result 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 sends the corresponding Msg1, the network device does not know that the terminal device is a random access initiated due to beam failure. process, or a random access process initiated for 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 contention-based random access to indicate the network device side The random access process is triggered due to beam failure, and the BFR MAC control element (Control Element, CE) can 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 will use the new beam to monitor the random access response on the BFR-specific search space on the corresponding BWP, that is to say, the network device will configure CORESET and CORESET on the BWP corresponding to the BFR in advance. Search space, this dedicated CORESET is only associated with this dedicated search space and is not associated with other search spaces. If within the random access response window, the terminal device monitors the downlink control information (Downlink Control Information, DCI) sent to it by the network device on the new beam on the corresponding BWP, it is considered that the beam recovery is successful.

For the case where the network device is not configured with BFR dedicated resources, that is, the aforementioned contention-based random access, the network device does not need to configure this dedicated search space, and the UE can monitor the PDCCH in the public search space.
