The embodiments of the present application will be described below in conjunction with the accompanying drawings.

Figure 2 is a schematic flow chart of a method for processing a beam failure of a secondary cell in an embodiment of this application. The method for processing a beam failure of a secondary cell in this embodiment can be applied to the terminal device in Figure 1. As shown in Figure 2, the method includes the following steps:

S110: When a beam failure occurs in the secondary cell, determine at least one first candidate beam in the secondary cell.

In the NR system, the cells in which the terminal equipment works include a primary cell and a secondary cell. The primary cell is responsible for radio resource control communication with the terminal equipment, and the secondary cell is used to provide additional radio resources. The number of primary cells in which the terminal device works is usually one, and the number of secondary cells can be multiple, that is, the terminal device can work in multiple secondary cells at the same time.

In this step, the secondary cell where the beam failure occurs is the secondary cell where the terminal device is currently working.

When a beam failure occurs in the secondary cell, the terminal device determines at least one first candidate beam in the secondary cell where the beam failure occurs. Wherein, the first candidate beam is the beam corresponding to the secondary cell where the beam failure occurs.

Optionally, the number of secondary cells where beam failure occurs is one or more. When the number of secondary cells where beam failure occurs is one, the terminal device executes the secondary cell beam failure processing method of this application based on the secondary cell; when the number of secondary cells where beam failure occurs is multiple, the terminal device executes based on each secondary cell The beam failure processing method of the secondary cell of the present application.

Optionally, the at least one first candidate beam may specifically include all beams corresponding to the secondary cell where the beam failure occurs.

S120: Acquire a parameter measurement result of a reference signal corresponding to each first candidate beam.

Wherein, the parameter measurement result of the reference signal is used to characterize the performance information of the first candidate beam.

After determining at least one first candidate beam, the terminal device further obtains the parameter measurement result of the reference signal corresponding to each first candidate beam, so that the terminal device can determine each first candidate beam based on the parameter measurement result of each first candidate beam The performance of the beam.

S130: Send beam failure processing information according to the parameter measurement result.

After acquiring the parameter measurement result of the reference signal corresponding to each first candidate beam, the terminal device sends the beam failure processing information based on the parameter measurement results corresponding to all the first candidate beams.

Optionally, the terminal device may send beam failure processing information to the network device corresponding to the terminal device (for example, the access network device in FIG. 1), so that the network device can perform corresponding actions according to the beam failure processing information sent by the terminal device. Beam failure processing.

The method for processing the beam failure of the secondary cell provided in this embodiment determines the candidate beam of the secondary cell and obtains the parameter measurement result of the reference signal of the candidate beam when the terminal device has a beam failure. Sending the beam failure processing information, so that the network device can perform corresponding beam failure processing based on the beam failure processing information. Therefore, the present application can solve the problem of lack of corresponding processing specifications for secondary cell beam failure in the prior art, and can perform corresponding beam failure processing when beam failure occurs, thereby improving the stability of the NR system.

In one embodiment, the reference signal (Reference Signal, RS) includes a synchronization signal block (Synchronous Signal Block, SSB) and/or a channel state information reference signal (Channel State Information Reference Signal, CSI-RS).

Among them, the synchronization signal block SSB refers to the signal sent by the network device to the terminal device in the NR system for the terminal to perform operations such as synchronization, system information acquisition, and measurement.

Specifically, the synchronization signal 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). The main function of the primary synchronization signal and the secondary synchronization signal is to help the terminal equipment identify the cell and synchronize with the cell. The physical broadcast channel contains the most basic system information such as the system frame number and intra-frame timing information. The terminal equipment successfully receives the synchronization signal block SSB is a prerequisite for its access to the cell.

When the network device communicates with the terminal device through multiple beams, the network device may send multiple synchronization signal blocks SSB on the multiple beams. For example, the network device uses N beams to transmit the N synchronization signal blocks SSB, where each beam of the N beams is used to transmit one synchronization signal block SSB.

Correspondingly, the terminal device receives multiple synchronization signal blocks SSB sent by the network device, and each synchronization signal block SSB corresponds to a beam. The terminal device can measure the synchronization signal block SSB to determine the optimal one or more receptions. The beam is used as the working beam.

The channel state information reference signal CSI-RS is mainly used for channel measurement in the LTE system.

Specifically, in the NR system, the channel state information reference signal CSI-RS is mainly used to: (1) Obtain channel state information for scheduling, link adaptation, and multiple-input multiple-output (MIMO). Output) related transmission settings; (2) Used for beam management, acquisition of beam shaping weights of terminal equipment and network equipment, used to support the beam management process; (3) Accurate time-frequency tracking, set in the system TRS (Tracking Reference Signal, tracking reference signal) to achieve; (4) for mobility management, in the system through the channel state information reference signal CSI-RS of the cell and neighboring cells to obtain and track, to complete the mobility management of the terminal equipment Related measurement requirements; (5) For rate matching, the function of rate matching at the RE (Resource Element) level of the data channel is completed through the setting of the zero-power channel state information reference signal CSI-RS.

Optionally, in this embodiment, the reference signal may only use the synchronization signal block SSB, that is, the terminal device determines the performance of the beam according to the parameter measurement result of the synchronization signal block SSB.

Optionally, in this embodiment, the reference signal may only use the channel state information reference signal CSI-RS, that is, the terminal device determines the performance of the beam according to the parameter measurement result of the channel state information reference signal CSI-RS.

Optionally, in this embodiment, the reference signal may simultaneously select the synchronization signal block SSB and the channel state information reference signal CSI-RS, that is, the terminal equipment according to the parameter measurement result of the synchronization signal block SSB and the channel state information reference signal CSI-RS The measurement results of the parameters are used to comprehensively determine the performance of the beam.

In this embodiment, the terminal device can determine the performance of each beam more accurately according to the parameter measurement result of the synchronization signal block SSB and/or the channel state information reference signal CSI-RS, thereby facilitating subsequent beam failure processing.

In one embodiment, the parameters of the measurement result include Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Signal Interference Noise Ratio (Signal Interference Noise Ratio, SINR) Any one of them.

Among them, the reference signal received power RSRP is the linear average of the received power (in watts) of the received power (in watts) on the resource elements carrying the reference signal on the considered measurement frequency bandwidth, and is a measurement of signal strength. The reference signal received power RSRP may specifically be Layer 1 Reference Signal Received Power (Layer 1 Reference Signal Received Power, L1-RSRP).

The reference signal received quality RSRQ is the ratio of the reference signal received power RSRP to the received signal strength signal indicator (RSSI), that is, the reference signal received quality RSRQ is the ratio of the reference signal received power RSRP and the received strength signal indicator RSSI The difference in dB is the unit.

The signal-to-interference and noise ratio SINR refers to the ratio of the strength of the received useful signal to the strength of the received interference signal (noise and interference). The signal-to-interference and noise ratio, SINR, may specifically be Layer 1 Signal to Interference plus Noise Ratio (L1-SINR).

Specifically, in this embodiment, any one of the above three parameters can be selected as a parameter to obtain the parameter measurement result corresponding to the reference signal.

For example, when the reference signal is the synchronization signal block SSB, if the reference signal received power RSRP is selected as the parameter, the reference signal received power RSRP measurement result of the synchronization signal block SSB is obtained; if the reference signal received quality RSRQ is selected as the parameter, the synchronization is obtained The RSRQ measurement result of the reference signal reception quality of the signal block SSB; if the signal-to-interference and noise ratio SINR is selected as a parameter, the signal-to-interference and noise ratio SINR measurement result of the synchronization signal block SSB is obtained.

For another example, when the reference signal is the channel state information reference signal CSI-RS, if the reference signal received power RSRP is selected as the parameter, the measurement result of the reference signal received power RSRP of the channel state information reference signal CSI-RS is obtained; if the reference signal is selected The received quality RSRQ is used as a parameter to obtain the reference signal received quality RSRQ measurement result of the channel state information reference signal CSI-RS; if the signal to interference noise ratio SINR is selected as the parameter, the signal to interference noise ratio of the channel state information reference signal CSI-RS is obtained SINR measurement result.

Optionally, when the synchronization signal block SSB and the channel state information reference signal CSI-RS are selected as the reference signals at the same time, the parameter types corresponding to the two reference signals are the same, that is, the two signals measure the same type of parameters.

For example, when the synchronization signal block SSB and the channel state information reference signal CSI-RS are selected as the reference signal at the same time, the reference signal received power RSRP can be selected as a parameter to obtain the reference signal received power RSRP measurement result of the synchronization signal block SSB and the channel state The RSRP measurement result of the reference signal received power of the information reference signal CSI-RS.

It can be understood that when the synchronization signal block SSB and the channel state information reference signal CSI-RS are selected as the reference signal at the same time, the reference signal reception quality RSRQ or the signal-to-interference and noise ratio SINR may also be selected as the parameter to obtain the corresponding measurement result.

Optionally, after the parameter measurement results of the two reference signals are obtained, the step of normalizing the parameter measurement results of the two reference signals is further included.

Specifically, first preset the respective weight coefficients of the synchronization signal block SSB and the channel state information reference signal CSI-RS, and obtain the reference signal received power RSRP measurement result of the synchronization signal block SSB and the reference signal of the channel state information reference signal CSI-RS. After the signal received power RSRP measurement result, according to the respective weight coefficients of the synchronization signal block SSB and the channel state information reference signal CSI-RS, the RSRP measurement result of the reference signal received power of the synchronization signal block SSB and the channel state information reference signal CSI-RS The RSRP measurement results of the reference signal received power are weighted and summed to obtain the final RSRP measurement results of the reference signal received power.

For example, assume that the weight coefficient corresponding to the synchronization signal block SSB is a, the weight coefficient corresponding to the channel state information reference signal CSI-RS is b, the RSRP measurement result of the reference signal received power of the synchronization signal block SSB is A, and the channel state information reference signal The RSRP measurement result of the reference signal received power of the CSI-RS is B, and the calculation formula of the final RSRP measurement result Y of the reference signal received power is: Y=a*A+b*B.

Optionally, the parameter type used can be selected according to actual application scenarios. For example, in the MU-MIMO (Multi-User Multiple-Input Multiple-Output) scenario, the signal-to-interference and noise ratio SINR is preferentially selected as the parameter, and in other cases, the reference signal received power RSRP may be preferentially selected as the parameter Wait.

In this embodiment, the terminal equipment can determine the performance of each beam more accurately according to the RSRP measurement result of the reference signal received power/reference signal received quality RSRQ measurement result/signal to interference and noise ratio SINR measurement result, thereby facilitating subsequent follow-up Beam failure processing.

In an embodiment, the secondary cell beam failure processing method further includes a processing step of determining whether a beam failure occurs in the secondary cell.

FIG. 3 is a schematic diagram of determining whether a beam failure occurs in a secondary cell in an embodiment of the application. As shown in FIG. 3, the processing steps for determining whether a beam failure occurs in a secondary cell specifically include S102 to S108.

S102: Acquire a parameter measurement result of a reference signal corresponding to the current beam in the secondary cell;

S104: Determine whether the parameter measurement result of the reference signal corresponding to the current beam is less than a second preset threshold;

S106: When a parameter measurement result of the reference signal corresponding to the current beam is less than a second preset threshold, determine that a beam failure occurs in the secondary cell;

S108: When the measurement result of the parameter of the reference signal corresponding to the current beam is greater than or equal to the second preset threshold, it is determined that no beam failure has occurred in the secondary cell.

Among them, the current beam is the beam currently used by the terminal device.

The second preset threshold is a preset threshold used to determine whether beam failure occurs, and the second preset threshold may be expressed as threshold-failure (failure threshold). It can be understood that the value of the second preset threshold may be different for different parameter types. For example, when determining whether a beam failure occurs, the second preset threshold corresponding to the reference signal received power RSRP and the second preset threshold corresponding to the signal-to-interference and noise ratio SINR are different, and the corresponding settings can be made based on the different parameter types. .

Optionally, when the reference signal is the synchronization signal block SSB, a block error rate (Block Error Ratio, BLER) may also be used to determine whether a beam failure occurs. When the block error rate is used as a parameter, the principle of determining whether the secondary cell has a beam failure is different from the principle of using the reference signal received power RSRP as a parameter to determine whether the secondary cell has a beam failure.

Specifically, the terminal device obtains the block error rate measurement result of the synchronization signal block SSB, and determines whether the block error rate measurement result is greater than the preset threshold value, and if the block error rate measurement result is greater than the preset threshold value, it is determined that the secondary cell has beam failure; The block rate measurement result is less than or equal to the preset threshold, and it is determined that no beam failure occurs in the secondary cell.

In this embodiment, the terminal device compares the parameter measurement result of the reference signal of the current beam with the second preset threshold, so as to determine whether a beam failure occurs in the secondary cell, and then can perform the secondary cell when a beam failure occurs in the secondary cell. The cell beam failure processing method ensures the stability of the NR system.

In one embodiment, sending the beam failure processing information according to the parameter measurement result includes: if the parameter measurement results of all the first candidate beams are less than the first preset threshold, sending the beam failure processing information according to the first preset strategy.

Among them, the first preset threshold value is less than the second preset threshold value, the first preset threshold value can be specifically expressed as threshold-discard (discard threshold), when the parameter measurement result is less than the first preset threshold value, it can be considered that the beam is at Unavailable state. At this time, the terminal device sends the beam failure processing information according to the first preset strategy.

Optionally, the first preset strategy specifically includes: if the parameter measurement result is less than the first preset threshold and the duration reaches the preset duration, sending a first message through the primary cell where the terminal device is located, and the first message is used to notify the network The secondary cell of the device is unavailable.

When the parameter measurement results of all the first candidate beams are less than the first preset threshold, the terminal device and the network device cannot communicate through the beam. At this time, the terminal device is further based on the length of time that the parameter measurement results are less than the first preset threshold To confirm whether the secondary cell can perform demodulation.

Specifically, if the parameter measurement result is less than the first preset threshold and the duration reaches the preset duration, it means that the beam performance is extremely poor and the secondary cell cannot demodulate. At this time, the terminal device cannot communicate with the network device through the secondary cell. Therefore, the terminal device sends the first message to the network device through the primary cell where it is located, and the network device can determine that the secondary cell is currently unavailable based on the first message.

Further, after the parameter measurement results are less than the first preset threshold for a period of time reaching the preset period of time, the terminal device confirms that the secondary cell cannot be demodulated, and therefore can disconnect the connection with the secondary cell to avoid waste of network resources.

Optionally, the first preset strategy specifically further includes: if the duration of the parameter measurement results is less than the first preset threshold and does not reach the preset duration, sending a second message through the primary cell where the terminal device is located, and the second message is used for Notify the network device that there is no available beam in the secondary cell.

When the parameter measurement results of all the first candidate beams are less than the first preset threshold, the terminal device and the network device cannot communicate through the beam. At this time, the terminal device is further based on the length of time that the parameter measurement results are less than the first preset threshold To confirm whether the secondary cell can be demodulated, so as to confirm whether the communication can be resumed.

Specifically, if the parameter measurement results are less than the first preset threshold and the duration does not reach the preset duration, it means that the beam performance is poor, but the secondary cell can resume communication through demodulation. At this time, the terminal device may not be disconnected from the Connect the secondary cell and send a second message to the network device through the primary cell where it is located. Based on the second message, the network device can determine that the secondary cell currently has no available beam, that is, there is no new beam identified (NBI) .

In one embodiment, sending the beam failure processing information according to the parameter measurement result includes: if there are beams with the parameter measurement result greater than or equal to the first preset threshold in the first candidate beam, and the parameter measurement results of all the first candidate beams are equal If it is less than the second preset threshold, the beam failure processing information is sent according to the second preset strategy.

When the parameter measurement results of all the first candidate beams are less than the second preset threshold, the terminal device cannot communicate with the network device through the secondary cell. At this time, if there are parameter measurement results in the first candidate beam that are greater than or equal to the first For a beam with a preset threshold, the beam with a measurement result of this parameter greater than or equal to the first preset threshold has poor performance, but at this time the secondary cell can perform demodulation to resume communication. At this time, the terminal device sends the beam failure processing information according to the second preset strategy.

Optionally, the second preset strategy includes: sending a second message through the primary cell where the terminal device is located, and the second message is used to notify the network device that there is no available beam in the secondary cell.

At this time, the terminal device may not disconnect the connection with the secondary cell, and send a second message to the network device through the primary cell where it is located. Based on the second message, the network device can determine that the secondary cell currently has no available beam, that is, it does not exist. New beam indication.

In one embodiment, sending the beam failure processing information according to the parameter measurement result includes: if there is a second candidate beam whose parameter measurement result is greater than or equal to a second preset threshold in the first candidate beam, and the parameters of all the first candidate beams If the measurement results are all less than the third preset threshold, the beam failure processing information is sent according to the third preset strategy;

Wherein, the third preset threshold is a value greater than the second preset threshold, the third preset threshold can be specifically expressed as threshold-failure-ad, if there is a parameter measurement result in the first candidate beam that is greater than or equal to the second preset threshold However, the parameter measurement results of the second candidate beam are all less than the third preset threshold. It can be considered that the performance of the second candidate beam is good. At this time, the terminal device sends the beam failure processing information according to the third preset strategy.

Optionally, the third preset strategy includes: sending a beam failure recovery request through the primary cell where the terminal device is located.

Specifically, when there is a second candidate beam whose parameter measurement result is greater than or equal to the second preset threshold in the first candidate beam, but the parameter measurement result of the second candidate beam is all less than the third preset threshold, the terminal device passes its location The primary cell sends a beam failure recovery request, which is used to notify the network device that the terminal device can perform beam failure recovery on the terminal device based on the second candidate beam, so that the terminal device and the network device can communicate again through the secondary cell. At this time, the secondary cell does not perform any operations to reduce signaling overhead.

Optionally, the third preset strategy includes: sending a beam failure recovery request through the primary cell and the secondary cell where the terminal device is located.

Specifically, when there is a second candidate beam whose parameter measurement result is greater than or equal to the second preset threshold value in the first candidate beam, but the parameter measurement result of the second candidate beam is all less than the third preset threshold value, the terminal device simultaneously passes its The primary cell and secondary cell where they are located send a beam failure recovery request. The beam failure recovery request is used to notify the network device that the terminal device can perform beam failure recovery based on the second candidate beam, so that the terminal device and the network device can use the secondary cell again Communication.

Specifically, when there is a third candidate beam whose parameter measurement result is greater than or equal to the third preset threshold in the first candidate beam, it indicates that the performance of the third candidate beam is better.
