The terms referred to in this application are explained first:

NR System: the NR system refers to a fifth Generation Mobile communication system (5 th Generation, 5G) dominated by the third Generation Partnership project (3 rd Generation Partnership project,3 gpp), in which enhanced Mobile Broadband (eMBB), large scale Machine communication (mtc), and high-reliability low-latency communication (URLLC) are defined as main application scenarios of 5G.

The 3GPP introduces a Carrier Aggregation (CA) technology that supports a larger transmission bandwidth by aggregating a plurality of consecutive or non-consecutive carriers. Cells participating in carrier aggregation are divided into a primary cell (PCell) and a secondary cell (SCell), where the PCell is a cell initially accessed by a User Equipment (UE) and is responsible for Radio Resource Control (RRC) communication with the UE, and the SCell is added during RRC reconfiguration and is used to provide additional Radio resources.

Failure of the beam: the working frequency of 5G can be up to several tens of GHz, and if high-frequency electromagnetic waves cannot be transmitted intensively, the path loss of the high-frequency electromagnetic waves is very serious, so that the high-frequency signals in 5G can be transmitted by adopting a beam forming (beam forming) technology. Because the energy of the signal is concentrated in a certain direction, the quality of the original signal beam is deteriorated or even unavailable due to factors such as shielding in the movement, and thus beam failure occurs.

The technical means of the present application will be described in detail with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Fig. 2 is a schematic flowchart of a method for processing a failure of a secondary cell beam in this embodiment, where the method for processing a failure of a secondary cell beam in this embodiment may be applied to the terminal device in fig. 1, and as shown in fig. 2, the method includes the following steps:

s110, when the beam failure occurs in the secondary cell, at least one first candidate beam is determined in the secondary cell.

In the NR system, the cells in which the terminal device operates include a primary cell and a secondary cell, where the primary cell is responsible for radio resource control communication with the terminal device, and the secondary cell is used to provide additional radio resources. The number of the primary cells in which the terminal device operates is usually one, and the number of the secondary cells may be multiple, that is, the terminal device may operate in multiple secondary cells simultaneously.

In this step, the secondary cell in which the beam failure occurs is the secondary cell in which the terminal device currently operates.

When the secondary cell has beam failure, the terminal equipment determines at least one first candidate beam in the secondary cell having beam failure. The first candidate beam is a beam corresponding to the secondary cell in which the beam failure occurs.

Optionally, the number of secondary cells in which beam failure occurs is one or more. When the number of the auxiliary cells with beam failure is one, the terminal equipment executes the auxiliary cell beam failure processing method based on the auxiliary cells; when the number of the secondary cells with beam failure is multiple, the terminal equipment executes the secondary cell beam failure processing method based on each secondary cell.

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

And S120, acquiring a parameter measurement result of the reference signal corresponding to each first candidate beam.

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

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

And S130, transmitting 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 beam failure processing information based on the parameter measurement results corresponding to all the first candidate beams.

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

In the method for processing a beam failure in a secondary cell provided in this embodiment, when a beam failure occurs in a terminal device, a candidate beam in the secondary cell is determined, a parameter measurement result of a reference signal of the candidate beam is obtained, and then beam failure processing information is sent to a corresponding network device according to the parameter measurement result, so that the network device can perform corresponding beam failure processing based on the beam failure processing information. Therefore, the method and the device can solve the problem that auxiliary cell beam failure corresponding processing specifications are lacked in the prior art, can perform corresponding beam failure processing when beam failure occurs, and improve the stability of the NR system.

In one embodiment, the Reference Signal (RS) includes a Synchronization Signal Block (SSB) and/or a Channel State Information Reference Signal (CSI-RS).

The synchronization signal block SSB is a signal that is sent by a network device in the NR system to a terminal device, and is used 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 (PSS), a Secondary Synchronization Signal (SSS), and a Physical Broadcast Channel (PBCH). The primary synchronization signal and the secondary synchronization signal mainly serve to help the terminal equipment to identify and synchronize with a cell, and the physical broadcast channel contains the most basic system information such as a system frame number, intra-frame timing information and the like. The successful reception of the synchronization signal block SSB by the terminal device 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 transmit multiple synchronization signal blocks SSB on the multiple beams. For example, the network device transmits the N synchronization signal blocks SSB using N beams, where each of the N beams is used to transmit one synchronization signal block SSB.

Correspondingly, the terminal device receives a plurality of synchronization signal blocks SSBs sent by the network device, each synchronization signal block SSB corresponds to a beam, and the terminal device may measure the synchronization signal blocks SSBs to determine an optimal one or more receiving beams as working beams.

The CSI-RS is mainly used for channel measurement in the LTE system.

Specifically, in the NR system, the CSI-RS is mainly used for: (1) Acquiring channel state information for scheduling, link adaptation and transmission setting related to MIMO (Multiple-Input Multiple-Output); (2) The method is used for beam management, and the acquisition of the shaped weight of the beam of the terminal equipment and the network equipment, and is used for supporting the beam management process; (3) Accurate time-frequency Tracking is realized by setting TRS (Tracking Reference Signal) in the system; (4) The method is used for mobility management, and measurement requirements related to the mobility management of terminal equipment are met by acquiring and tracking channel state information reference signals (CSI-RS) of a local cell and an adjacent cell in a system; (5) For rate matching, the RE (Resource Element) level rate matching function of the data channel is completed through setting of the channel state information reference signal CSI-RS with zero power.

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 CSI-RS, that is, the terminal device determines the performance of the beam according to the measurement result of the parameter of the 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 device comprehensively determines the performance of the beam according to the parameter measurement result of the synchronization signal block SSB and the parameter measurement result of the channel state information reference signal CSI-RS.

In this embodiment, the terminal device may 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, so as to facilitate subsequent beam failure processing.

In one embodiment, the parameter of the measurement result includes any one of Reference Signal Receiving Power (RSRP), reference Signal Receiving Quality (RSRQ), and Signal Interference Noise Ratio (SINR).

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

The reference Signal Received quality RSRQ is a ratio of the reference Signal Received power RSRP to the Received Signal Strength Indicator (RSSI), i.e., the reference Signal Received quality RSRQ is a difference in dB between the reference Signal Received power RSRP and the Received Signal Strength indicator RSSI.

The signal to interference plus noise ratio SINR refers to the ratio of the strength of the received desired signal to the strength of the received interfering signal (noise and interference). The SINR may be, in particular, a Layer-to-Layer SINR (Layer 1 Signal to Interference plus Noise ratio, L1-SINR).

Specifically, in this embodiment, any one of the three parameters may be selected as a parameter, so as to obtain a 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 a parameter, a reference signal received quality RSRQ measurement result of the synchronous signal block SSB is obtained; if the signal to interference plus noise ratio SINR is selected as the parameter, the signal to interference plus noise ratio SINR measurement result of the synchronization signal block SSB is obtained.

For another example, when the reference signal is a channel state information reference signal CSI-RS, if reference signal received power RSRP is selected as a parameter, a reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS is obtained; if Reference Signal Receiving Quality (RSRQ) is selected as a parameter, a Reference Signal Receiving Quality (RSRQ) measuring result of a channel state information reference signal (CSI-RS) is obtained; and if the signal interference noise ratio SINR is selected as a parameter, obtaining a signal interference noise ratio SINR measurement result of the channel state information reference signal CSI-RS.

Optionally, when the synchronization signal block SSB and the channel state information reference signal CSI-RS are simultaneously selected as the reference signals, the types of parameters corresponding to the two reference signals are the same, that is, both 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 simultaneously selected as reference signals, reference signal received power RSRP may be selected as a parameter, thereby obtaining a reference signal received power RSRP measurement result of the synchronization signal block SSB and a reference signal received power RSRP measurement result of the channel state 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 simultaneously selected as the reference signal, the reference signal received quality RSRQ or the signal to interference noise ratio SINR may also be selected as the parameter, so as to obtain the corresponding measurement result.

Optionally, after obtaining the parameter measurement results of the two reference signals, the method further includes a step of performing normalization processing on the parameter measurement results of the two reference signals.

Specifically, weight coefficients corresponding to a synchronization signal block SSB and a channel state information reference signal CSI-RS are preset, and after a reference signal received power RSRP measurement result of the synchronization signal block SSB and a reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS are obtained, the reference signal received power RSRP measurement result of the synchronization signal block SSB and the reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS are weighted and summed according to the weight coefficients corresponding to the synchronization signal block SSB and the channel state information reference signal CSI-RS, so as to obtain a final reference signal received power RSRP measurement result.

For example, if the weighting factor corresponding to the synchronization signal block SSB is a, the weighting factor corresponding to the channel state information reference signal CSI-RS is B, the reference signal received power RSRP measurement result of the synchronization signal block SSB is a, and the reference signal received power RSRP measurement result of the channel state information reference signal CSI-RS is B, the final reference signal received power RSRP measurement result Y is calculated as: y = a + B.

Optionally, the type of parameters used may be selected according to the actual application scenario. For example, in a MU-MIMO (Multi-User Multiple-Input Multiple-Output) scenario, the SINR may be preferentially selected as a parameter, and otherwise, the RSRP may be preferentially selected as a parameter.

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

In one embodiment, the method for processing beam failure of the secondary cell further comprises a processing step of determining whether beam failure occurs in the secondary cell.

Fig. 3 is a schematic diagram illustrating determining whether a beam failure occurs in a secondary cell in the embodiment of the present application, and as shown in fig. 3, the processing step of determining whether a beam failure occurs in the secondary cell specifically includes S102 to S108.

S102, acquiring a parameter measurement result of a reference signal corresponding to a current wave beam in an auxiliary cell;

s104, judging whether the parameter measurement result of the reference signal corresponding to the current wave beam is smaller than a second preset threshold value or not;

s106, when the parameter measurement result of the reference signal corresponding to the current beam is smaller than a second preset threshold value, determining that the beam failure occurs in the secondary cell;

and S108, when the parameter measurement result of the reference signal corresponding to the current beam is greater than or equal to a second preset threshold, determining that the beam failure does not occur in the secondary cell.

And the current beam is the beam currently used by the terminal equipment.

The second preset threshold is a preset threshold for determining whether a beam failure occurs, and may be represented as a threshold-failure. It will be appreciated that the parameter types may be different and the value of the second preset threshold may be different. For example, when determining whether a beam failure occurs, the second preset threshold corresponding to the reference signal received power RSRP is different from the second preset threshold corresponding to the signal to interference plus noise ratio SINR, and specifically, the second preset threshold may be set correspondingly based on different parameter types.

Optionally, when the reference signal is the synchronization signal Block SSB, a Block Error rate (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 beam failure occurs in the secondary cell is different from the principle of determining whether the beam failure occurs in the secondary cell by using the Reference Signal Received Power (RSRP) as a parameter.

Specifically, the terminal device obtains a block error rate measurement result of the synchronization signal block SSB, and determines whether the block error rate measurement result is greater than a preset threshold, and if the block error rate measurement result is greater than the preset threshold, determines that the secondary cell has a beam failure; and if the block error rate measurement result is less than or equal to a preset threshold value, determining 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 the beam failure occurs in the secondary cell, and then execute the secondary cell beam failure processing method when the beam failure occurs in the secondary cell, thereby ensuring the stability of the NR system.

In one embodiment, transmitting the beam failure handling information according to the parameter measurement result includes: and if the parameter measurement results of all the first candidate beams are smaller than a first preset threshold value, transmitting beam failure processing information according to a first preset strategy.

The first preset threshold is a value smaller than the second preset threshold, and the first preset threshold may specifically be represented as a threshold-discard threshold, and when the parameter measurement result is smaller than the first preset threshold, the beam may be considered to be in an unavailable state. At this time, the terminal device transmits the beam failure processing information according to a first preset strategy.

Optionally, the first preset policy specifically includes: and if the parameter measurement results are all less than the duration of the first preset threshold value and reach the preset duration, sending a first message through the main cell where the terminal equipment is located, wherein the first message is used for informing the network equipment that the auxiliary cell is unavailable.

When the parameter measurement results of all the first candidate beams are smaller than the first preset threshold, the terminal device and the network device cannot communicate through the beams, and at this time, the terminal device further determines whether the secondary cell can perform demodulation based on the duration that the parameter measurement results are smaller than the first preset threshold.

Specifically, if the duration that the parameter measurement results are all smaller than the first preset threshold reaches the preset duration, it indicates that the beam performance is extremely poor, and the auxiliary cell cannot demodulate, and at this time, the terminal device cannot communicate with the network device through the auxiliary cell.

Further, after the duration that the parameter measurement results are all smaller than the first preset threshold reaches the preset duration, the terminal device confirms that the auxiliary cell cannot demodulate, so that the connection with the auxiliary cell can be disconnected, and waste of network resources is avoided.

Optionally, the first preset policy specifically further includes: and if the time length of the parameter measurement results which are all smaller than the first preset threshold value does not reach the preset time length, sending a second message through the main cell where the terminal equipment is located, wherein the second message is used for informing the network equipment that no available wave beam exists in the auxiliary cell.

When the parameter measurement results of all the first candidate beams are smaller than the first preset threshold, the terminal device and the network device cannot communicate through the beams, and at this time, the terminal device further confirms whether the secondary cell can demodulate based on the duration that the parameter measurement results are smaller than the first preset threshold, so as to confirm whether the communication can be resumed.

Specifically, if the durations of the parameter measurement results that are all smaller than the first preset threshold do not reach the preset duration, it is indicated that the beam performance is poor, but the secondary cell may recover communication through demodulation, 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 the terminal device is located, and the network device may determine, based on the second message, that the secondary cell does not have a currently available beam, that is, there is no New Beam Identified (NBI).

In one embodiment, transmitting the beam failure handling information according to the parameter measurement result includes: and if the first candidate beams have beams with parameter measurement results larger than or equal to a first preset threshold value and the parameter measurement results of all the first candidate beams are smaller than a second preset threshold value, transmitting beam failure processing information according to a second preset strategy.

When the parameter measurement results of all the first candidate beams are smaller than the second preset threshold, the terminal device cannot communicate with the network device through the secondary cell, at this time, if there is a beam with a parameter measurement result greater than or equal to the first preset threshold in the first candidate beams, the beam performance of the parameter measurement result greater than or equal to the first preset threshold is poor, but at this time, the secondary cell may demodulate to recover the communication. At this time, the terminal device transmits the beam failure processing information according to a second preset strategy.

Optionally, the second preset policy includes: and sending a second message through the primary cell where the terminal equipment is located, wherein the second message is used for informing the network equipment that no beam is available in the secondary cell.

At this time, the terminal device may not disconnect from the secondary cell, and send a second message to the network device through the primary cell where the terminal device is located, and the network device may determine, based on the second message, that the secondary cell does not have a currently available beam, that is, there is no new beam indication.

In one embodiment, transmitting the beam failure handling information according to the parameter measurement result includes: if a second candidate beam with the parameter measurement result larger than or equal to a second preset threshold exists in the first candidate beams and the parameter measurement results of all the first candidate beams are smaller than a third preset threshold, sending beam failure processing information according to a third preset strategy;

if a second candidate beam with a parameter measurement result greater than or equal to the second preset threshold exists in the first candidate beam, but the parameter measurement results of the second candidate beam are all less than the third preset threshold, it may be considered that the performance of the second candidate beam is good, and at this time, the terminal device sends the beam failure processing information according to a third preset strategy.

Optionally, the third preset policy includes: and sending a beam failure recovery request through a main cell in which the terminal equipment is positioned.

Specifically, when a second candidate beam with a parameter measurement result greater than or equal to a second preset threshold exists in the first candidate beam, but the parameter measurement results of the second candidate beam are all smaller than a third preset threshold, the terminal device sends a beam failure recovery request through the primary cell where the terminal device is located, where the beam failure recovery request is used to notify the network device that the beam failure recovery can be performed 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 operation to reduce signaling overhead.

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

Specifically, when a second candidate beam with a parameter measurement result greater than or equal to a second preset threshold exists in the first candidate beam, but the parameter measurement results of the second candidate beam are all smaller than a third preset threshold, the terminal device sends a beam failure recovery request through the primary cell and the secondary cell where the terminal device is located at the same time, and the beam failure recovery request is used for notifying the network device that the beam failure recovery can be performed 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.

In one embodiment, transmitting the beam failure handling information according to the parameter measurement result includes: and if a third candidate beam with the parameter measurement result larger than or equal to a third preset threshold exists in the first candidate beams, transmitting the beam failure processing information according to a fourth preset strategy.

Specifically, when a third candidate beam with a parameter measurement result greater than or equal to a third preset threshold exists in the first candidate beam, it is indicated that the performance of the third candidate beam is better, and at this time, the terminal device sends beam failure processing information according to a fourth preset strategy.

Optionally, the fourth preset policy includes: and sending a beam failure recovery request through the secondary cell.

Specifically, when a third candidate beam with a parameter measurement result greater than or equal to a third preset threshold exists in the first candidate beams, the terminal device sends a beam failure recovery request through the secondary cell, where the beam failure recovery request is used to notify the network device that the beam failure recovery can be performed on the terminal device based on the third candidate beam, so that the terminal device and the network device can communicate again through the secondary cell.

In one embodiment, the transmission mode of the beam failure recovery request includes: and transmitting based on a Physical Uplink Control Channel (PUCCH).

Optionally, the sending method of the beam failure recovery request further includes: transmission is Based on Contention Based Random Access (CBRA).

Optionally, the sending method of the beam failure recovery request further includes: and transmitting based on non-Contention Free Random Access (CFRA).

Specifically, when the terminal device sends the beam failure recovery request through the primary cell in which the terminal device is located, the beam failure recovery request may be specifically sent to the network device by using a sending method based on physical uplink control channel sending, so as to reduce signaling overhead.
