Background

High Frequency (HF) of a New air interface (NR, New Radio) of a fifth generation mobile communication (5G) system usually adopts High Beam gain provided by a Beam Forming (BF) technology to counter the problem of large attenuation of High Frequency signals. The beamforming that may be employed by the 5G NR includes: analog forming, digital forming and digital-analog mixed forming, wherein a transmitting end needs to determine an optimal transmitting beam, and a receiving end needs to determine an optimal receiving beam. Generally, determining the optimal transmit and receive analog beams is performed by beam training, and the optimal transmit and receive beams are determined based on the measured power strength of a Reference Signal (RS) or pilot representing the beam direction.

However, the high frequency signal subjected to beamforming has a short wavelength and a narrow Beam, and thus, while obtaining a high gain, the high frequency signal is often affected by a situation (for example, passing of pedestrians or automobiles) that a transmission/reception Beam used by a control channel or a data channel blocks a link (BPL), or a transmission quality of the current BPL is deteriorated due to movement or rotation of the terminal itself, which may cause interruption of signal propagation, and thus, control information and data information cannot be effectively transmitted.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

According to an aspect of the embodiments of the present invention, an information transmission method is provided, which is applied to a network device side, where the network device may be a base station, an access Point, and/or a Transfer Receiving Point (TRP). As shown in fig. 1, the information transmission method specifically includes the following steps:

step 11: when a first transceiving beam used by a transmission channel between the network equipment and a link BPL meets a preset transmission condition, generating a request message of a BPL recovery event of the transmission channel.

The transport channel herein includes a control channel and/or a data channel. Taking the data channel as an example, the first BPL may be one BPL or multiple BPLs, and when the data channel uses multiple BPLs, all the BPLs used by the data channel are monitored at the same time to determine whether the BPLs meet the preset transmission condition corresponding to the BPL recovery event triggering generation of the data channel. By monitoring the data channel, some situations occurring in the data channel can be known in real time, such as: the situation that the data information cannot be normally transmitted due to the blocking of the BPL used by the NR-PDSCH, and the situation that the data information cannot be normally transmitted due to the degradation of the BPL quality of the data channel caused by the rotation or movement of the terminal.

The above describes a scenario for triggering a BPL recovery event requiring a data channel, and the following describes a scenario for triggering a BPL recovery event requiring a control channel. Similar to the data channel, the first BPL used by the control channel may be one BPL or a plurality of BPLs, and the BPL used by the control channel may be the same as or different from the BPL used by the data channel. When the control channel uses a plurality of BPLs, all the BPLs used by the control channel are monitored simultaneously to judge whether the BPLs meet preset transmission conditions corresponding to BPL recovery events triggering generation of the control channel. By monitoring the control channel, some situations occurring in the control channel can be known in real time, such as: the situation that data information cannot be normally transmitted due to blocking of the BPL used by the NR-PDCCH, and the situation that control information cannot be normally transmitted due to degradation of the BPL quality caused by rotation or movement of the terminal in the control channel. It should be noted that the trigger condition for determining the BPL recovery event of the data channel may be different from the trigger condition for determining the BPL recovery event of the control channel.

Specifically, step 11 includes: and when the BPL of a first transceiving beam pair link used by a transmission channel between the network equipment and the network equipment meets a preset transmission condition, determining that the BPL of the transmission channel is invalid. And after determining that the BPL of the transmission channel is invalid and when determining that the third BPL meets the preset request condition, generating a request message of a BPL recovery event of the transmission channel.

Wherein, the third BPL is the BPL except the first BPL in the BPL corresponding to the transmission channel. It is noted that the third BPL may be 0 BPL (i.e., no other BPL than the first BPL can be found), 1 BPL, or multiple BPLs. And when the monitored third BPL meets the preset request condition, generating a request message of a BPL recovery event of the corresponding transmission channel. The different types of request messages correspond to different types of BPL recovery events of the transmission channels, and the different types of BPL recovery events of the transmission channels correspond to different preset request conditions. The sets of BPLs used for the control channel and the data channel may be the same or different, and the BPL currently used for the control channel and the BPL currently used for the data channel may be the same or different. The BPLs corresponding to the control channel other than the currently used BPL may be the same as, different from, or partially the same as the BPLs corresponding to the data channel other than the currently used BPL. Similarly, the triggering condition for determining the third BPL of the BPL recovery event of the data channel may be different from the triggering condition for determining the third BPL of the BPL recovery event of the control channel.

Further, after determining that the BPL of the transmission channel is invalid and when determining that the third BPL meets the preset request condition, the step of generating the request message of the BPL recovery event of the transmission channel specifically includes: when the third BPL is determined to meet the first preset request condition, generating a first request message of a BPL switching event of a transmission channel; or when the third BPL is determined to meet the second preset request condition, generating a second request message of the BPL training event of the transmission channel.

Specifically, taking the data channel as an example, after determining that the BPL of the data channel is invalid and when determining that the third BPL meets the preset request condition, the step of generating the request message of the BPL recovery event of the data channel specifically includes: when the third BPL is determined to meet the first preset request condition, generating a first request message of a BPL switching event of a data channel; or when the third BPL is determined to meet the second preset request condition, generating a second request message of the BPL training event of the data channel. Similarly, taking the control channel as an example, when it is determined that the third BPL satisfies the preset request condition after determining that the BPL of the control channel is failed, the step of generating the request message of the BPL recovery event of the control channel specifically includes: when the third BPL is determined to meet the first preset request condition, generating a first request message of a BPL switching event of a control channel; or when the third BPL is determined to meet the second preset request condition, generating a second request message of the BPL training event of the control channel.

Wherein the first request message includes: the BPL information of the first BPL, and/or the switching target BPL information determined according to the last beam training or beam measurement; the second request message includes: the BPL information of the first BPL and/or the recommended training mode information of the beam training.

The recommended training mode information of the re-beam training is different according to different types of BPL failures of the transmission channel (control channel and/or data channel). Specifically, the beam training mode includes: p1, the terminal measures different TRP transmit beams to support selection of TRP transmit beam/terminal receive beam; p2, the terminal measures different TRP transmit beams to support selection of TRP transmit beams; p3, UE uses beamforming to enable UE to select the UE's receive beam by measuring the same TRP transmit beam.

Specifically, when the cause of BPL failure of the transmission channel (control channel and/or data channel) is blocking, the P1, P2 or P3 mode may be recommended; when the terminal rotates, P3 can be preferentially recommended; when the terminal moves, a P1, P2 or P3 mode may be recommended.

Specifically, how to determine whether to trigger the first request message or the second request message may be implemented by: the UE can find a switching target BPL higher than a preset threshold value in a beam training RS corresponding to the current BPL sent by the network equipment, and then trigger a first request message of a beam switching event; and if the UE cannot find the BPL higher than the preset threshold value in the beam training RS corresponding to the current BPL sent by the network equipment, triggering a second request message for carrying out a beam training event.

Specifically, after the step of generating the request message for the BPL recovery event of the transmission channel when it is determined that the third BPL satisfies the preset request condition after determining that the BPL of the transmission channel is failed, especially when it is determined that the third BPL satisfies the preset request condition after determining that the BPL of the data channel is failed, the step of generating the request message for the BPL recovery event of the data channel further includes: determining handover target BPL information of a transmission channel (e.g., a data channel) according to the last beam training or beam measurement; determining and updating Channel State Information (CSI) according to the switching target BPL information; and sending the updated CSI to the network equipment through the pre-allocated first time-frequency resource. That is, after the BPL handover event is triggered, in addition to reporting the first request message to the network device, the updated CSI obtained based on the handover target BPL may be further reported, or the updated CSI obtained based on the unblocked BPL and the handover target BPL together may be further reported.

Specifically, if the CSI reporting time of the UE is not reached or the UE is just at the CSI reporting time, reporting the updated CSI on the predefined first time-frequency resource, where updating the CSI specifically may include: the MIMO transmission scheme, Rank Indication (RI), Channel Quality Indication (CQI), Precoding Matrix Indication (PMI), and the like of the updated CSI (reporting that the updated CSI can quickly resume data transmission).

Or, the UE may just be at the CSI reporting time, and may send the updated CSI on the corresponding feedback channel (e.g., NR-PUCCH, NR-PUSCH), which may include: MIMO transmission scheme, RI, CQI, PMI information, etc., to enable fast recovery of information transmission.

Step 12: the request message is sent to the network device.

When the terminal determines that the third BPL meets the preset request condition, the terminal generates a corresponding request message and reports the request message to the network device, so that the network device can determine a corresponding BPL recovery policy according to the real-time transmission condition of the transmission channel (such as a control channel and/or a control channel) and the terminal, so as to ensure the transmission quality of the control channel and the data channel.

In the prior art, a terminal can track and monitor a transmission channel through periodic beam training reporting and periodic Channel State Information (CSI) reporting, but the effectiveness is poor, and the real-time condition of the transmission channel cannot be reported to a network device quickly.

Step 12 may be specifically implemented in the following manner: carrying the request message by response or non-response ACK/NACK information, and sending the request to the network equipment; or, in the second mode, the request message is sent to the network device through a preset notification message.

In the first mode, the request message is carried by the acknowledgement or non-acknowledgement ACK/NACK information.

And the event state is increased along with the reporting of the ACK/NACK by increasing the bit number of the ACK/NACK information. The extended ACK/NACK may be referred to as enhanced ACK/NACK. Specifically, how to expand, a new indication field may be added to the original ACK/NACK, or the enhanced ACK/NACK may be uniformly encoded while carrying ACK/NACK information and a request message.

Specifically, the enhanced ACK/NACK reporting notification may be sent in a beam scanning manner to improve reliability. In particular, the reporting notification of the enhanced ACK/NACK is sent with beam scanning only when the first BPL is blocked. When the request message is the first request message, the enhanced ACK/NACK further includes BPL information where blocking occurs or target BPL information for handover. When the request message is a second request message, the enhanced ACK/NACK further includes information of a BPL in which blocking occurs and/or information of a recommended training mode of beam training.

Further, as shown in the following table, when the coding of the enhanced ACK/NACK is different, the indicated request message is different.

For the report of the enhanced ACK/NACK, the time-frequency resource of the prior ACK/NACK can be adopted for transmission, wherein the total bit number is increased because the ACK/NACK carries the request message, and the coding rate of the time-frequency resource of the prior ACK/NACK needs to be reduced when the transmission is carried out. Further, in addition to the above transmission mode, the ACK/NACK information carrying the request message may be sent to the network device by obtaining the time-frequency resource allocated by the network device according to the data amount of the ACK/NACK information. That is, the step of sending the request message to the network device through the ACK/NACK information may include: acquiring time-frequency resources distributed by the network equipment according to the data volume of the ACK/NACK information; and sending the ACK/NACK information carrying the request message to the network equipment through the time-frequency resource. In this way, the base station can allocate resources according to the data quantity of the enhanced ACK/NACK by keeping the coding rate of the prior ACK/NACK, and allocate more time-frequency resources to the enhanced ACK/NACK when the data quantity of the enhanced ACK/NACK is large.

Further, the terminal may always feed back enhanced ACK/NACK information to the network device to inform the network device whether BPL recovery is required and the transmission result of the current information. In order to further save the signaling overhead of the feedback information, the terminal may send the enhanced ACK/NACK information only when needing to perform BPL recovery, and send the standard ACK/NACK information in other scenarios, which involves the problem of switching between the enhanced ACK/NACK information and the standard ACK/NACK information. The standard ACK/NACK information is the existing ACK/NACK information, that is, the standard ACK/NACK information is only used for indicating the reception result of the information, where ACK is used for indicating correct reception and NACK is used for indicating incorrect reception. In the embodiment of the invention, the following modes are adopted to carry out switching control on two different ACK/NACK information, specifically, the switching control mode comprises a terminal active switching mode and a base station indication switching mode. The method I comprises the following steps of: before the step of sending the request to the network device by carrying the request message with the acknowledge or non-acknowledge ACK/NACK information, the method further comprises: and the terminal determines whether to adopt response or non-response ACK/NACK information to carry the request message according to the generated request message. That is, the terminal determines whether to adopt standard acknowledgement or non-acknowledgement ACK/NACK information feedback or enhanced ACK/NACK information feedback according to whether the request message is generated. Specifically, after generating a request message of a BPL recovery event, the terminal autonomously adopts enhanced ACK/NACK information to carry the request message and reports the request message to the network equipment, and the network equipment detects the enhanced ACK/NACK information in a blind detection mode and the like; if the terminal does not generate the request message of the BPL recovery event, the standard ACK/NACK information is autonomously fed back to the network equipment, and the network equipment detects the standard ACK/NACK information in a blind detection mode and the like. Or, the second mode is that the base station indicates the switching mode: and the terminal determines whether to adopt response or non-response ACK/NACK information to carry the request message according to the indication information sent by the network equipment. That is, the network device generates an indication message according to the information amount of the current or to-be-transmitted information or the transmission performance of the current transmission channel, where the indication message is used to indicate which ACK/NACK information is used by the terminal. The information amount of the information to be transmitted is the data amount or the data packet size of the information to be transmitted. Specifically, when the network device determines that beam blocking may occur, the terminal is configured through downlink signaling to perform feedback with enhanced ACK/NACK information, and then the terminal reports the generated request information to the network device by using the enhanced ACK/NACK after BPL fails; otherwise, the network equipment configures the terminal to feed back the standard ACK/NACK information through the downlink signaling. It is worth pointing out that in this scenario, the network device can correctly detect the ACK/NACK information without blind detection of the ACK/NACK information.

In the second mode, the step of sending the request message to the network device through the preset notification message specifically includes: and sending the preset notification message carrying the request message to the network equipment through the pre-allocated second time-frequency resource.

The second mode is to report a notification message by using a special event, and send a first request message for triggering a beam switching event or a second request message for triggering a beam training event on a predefined second time-frequency resource, where the first request message is unrelated to ACK/NACK, and for example, a similar RACH mechanism may be used.

Step 13: and recovering information transmission between the network equipment through the second BPL determined by the network equipment for the transmission channel according to the request message.

For example, the terminal determines whether the BPL of the data channel fails by monitoring the transmission quality of the first BPL employed by the data channel, and further monitors the condition of the third BPL to determine what type of BPL recovery event is triggered when the BPL of the data channel fails. Therefore, the network equipment determines the most appropriate BPL recovery strategy according to the request information and the terminal, and realizes the rapid recovery of the BPL, so that the data information can be transmitted through the new BPL, and the continuity of data transmission is ensured. Or, the terminal determines whether the BPL of the control channel fails by monitoring the transmission quality of the first BPL adopted by the control channel, and further monitors the condition of the third BPL to determine what type of BPL recovery event is triggered when the BPL of the control channel fails. Therefore, the network equipment determines the most appropriate BPL recovery strategy according to the request information and the terminal, and realizes the rapid recovery of the BPL, so that the control information can be transmitted through the new BPL, and the transmission consistency of the control information is ensured.

In summary, in the embodiments of the present invention, through monitoring the control channel and the data channel, after determining that the BPL of the control channel or the data channel fails, the terminal determines a request message of a BPL recovery event and sends the request message to the network device, so as to implement recovery of the BPL of the control channel and the data channel by determining a policy for recovering the BPL with the network device, thereby ensuring consistency of transmission of the control information and the data information.

Further, as shown in fig. 2, step 11 specifically includes:

step 21: the reception quality of a reference signal corresponding to a first BPL used by a transmission channel between network devices is acquired.

The Reference Signal includes a BPL training Reference Signal (RS) corresponding to the first BPL and/or a Demodulation Reference Signal (DMRS) corresponding to the first BPL. Specifically, the terminal monitors the quality of the DMRS or the beam training RS corresponding to the data channel, and when the quality of the DMRS or the beam training RS is poor, it may cause that data cannot be received in an original Multiple-Input Multiple-Output (MIMO) transmission mode (transmission mode), such as open-loop MIMO, closed-loop MIMO, or a rank (rank) and a precoding matrix selected in the original MIMO state.

Step 22: when the reception quality of the reference signal satisfies a first preset transmission condition, it is determined that the first BPL is blocked.

The reception quality includes: and the quality of the BPL training RS corresponding to the first BPL and/or the quality of the DMRS corresponding to the first BPL. How to determine that the first BPL is blocked will be described below with respect to these two quality parameters, respectively.

Specifically, when the terminal UE measures that the quality of the DMRS associated with the control channel or the data channel is lower than a first DMRS quality threshold, or the change rate of the DMRS quality exceeds a first DMRS change rate threshold, or the quality of the DMRS is lower than a second DMRS quality threshold and lasts for a first preset time, the first BPL is determined to be blocked. Wherein the value of the second DMRS quality threshold is generally higher than the value of the second DMRS quality threshold. For example: when the data of the NR-PDSCH is transmitted on only one BPL, the corresponding DMRS is also transmitted by using the BPL, and the blocking of the BPL can be determined when the UE monitors that the quality measured by the DMRS port is lower than a threshold. Alternatively, when data of the NR-PDSCH is transmitted on a plurality of BPLs but the corresponding DMRS ports are not precoded across the BPLs and are transmitted orthogonally, i.e., there is a respective DMRS port on each BPL, the UE may determine whether the corresponding BPL is blocked according to the quality measured by the DMRS port on each BPL. It is worth noting, among other things, that the detection threshold value of the DMRS associated with the control channel may be different from the detection threshold value of the DMRS associated with the data channel.

Specifically, the terminal may further measure the quality (e.g., CSI-RS) of the beam training RS, and determine that the first BPL is blocked when the quality of the beam training RS corresponding to the BPL transmitting the control channel or the data channel is lower than a first RS quality threshold, or the quality change rate of the beam training RS exceeds a first RS change rate threshold, or the quality of the beam training RS is lower than a second RS quality threshold and continues for a second predetermined time. It is worth noting that the beam training RS quality threshold corresponding to the BPL of the control channel may be different from the beam training RS quality threshold corresponding to the BPL of the data channel.

Step 23: and when the receiving quality of the reference signal meets a second preset transmission condition, determining that the terminal rotates.

Similar to the process of determining whether the first BPL is blocked, the terminal may further determine whether the terminal is rotated according to the quality of the BPL training RS corresponding to the first BPL and/or the quality of the DMRS corresponding to the first BPL.

Specifically, the terminal UE measures that the quality of the DMRS associated with the control channel and the data channel is lower than a third DMRS quality threshold, or the change rate of the DMRS quality exceeds a second DMRS change rate threshold, or the quality of the DMRS is lower than a fourth DMRS quality threshold and lasts for a third preset time, and the terminal is determined to rotate. Wherein the value of the fourth DMRS quality threshold is generally higher than the value of the third DMRS quality threshold. It is worth pointing out that the third DMRS quality threshold has a different value than the first DMRS quality threshold, and the third predetermined time is different from the first predetermined time.

Specifically, the terminal measures the quality (for example, CSI-RS) of the beam training RS, and determines that the terminal rotates when the quality of the beam training RS corresponding to the BPL transmitting the control channel or the data channel is lower than a third RS quality threshold, or the quality change rate of the beam training RS exceeds a second RS change rate threshold, or the quality of the beam training RS is lower than a fourth RS quality threshold and continues for a fourth predetermined time. And the value of the third RS quality threshold is different from that of the first RS quality threshold, and the fourth preset time is different from the second preset time.

Specifically, step 23 includes: acquiring a terminal state of a terminal; and when the receiving quality of the reference signal meets a second preset transmission condition and the terminal state meets a first preset state condition, determining that the terminal rotates.

That is, the condition for determining whether the terminal is rotated may further include state information of the terminal itself in addition to the reception quality. The terminal state may be measured by a sensor (e.g., a gyroscope or a gravity sensor) built in the terminal, and then it is determined whether the terminal is rotated.

Step 24: and when the receiving quality of the reference signal meets a third preset transmission condition, determining that the terminal moves.

Similar to the process of determining whether the terminal rotates, the terminal may further determine whether the terminal moves according to the quality of the BPL training RS corresponding to the first BPL and/or the quality of the DMRS corresponding to the first BPL.

Specifically, the terminal UE measures that the quality of the DMRS associated with the control channel and the data channel is lower than a fifth DMRS quality threshold, or the change rate of the DMRS quality exceeds a third DMRS change rate threshold, or the quality of the DMRS is lower than a sixth DMRS quality threshold and lasts for a fifth preset time, and the terminal is determined to move. Wherein the value of the sixth DMRS quality threshold is generally higher than the value of the fifth DMRS quality threshold. It is worth pointing out that the fifth DMRS quality threshold is different from the first and third DMRS quality thresholds, and the fifth predetermined time is different from the first and third predetermined times.

Specifically, the terminal measures the quality of the beam training RS, and determines that the terminal moves when the quality of the beam training RS corresponding to the BPL transmitting the control channel or the data channel is lower than a fifth RS quality threshold, or the quality change rate of the beam training RS exceeds a third RS change rate threshold, or the quality of the beam training RS is lower than a sixth RS quality threshold and continues for a sixth predetermined time. And the value of the fifth RS quality threshold is different from the values of the first RS quality threshold and the third RS quality threshold, and the sixth preset time is different from the values of the second preset time and the fourth preset time.

Specifically, step 24 comprises: acquiring a terminal state of a terminal; and when the receiving quality of the reference signal meets a third preset transmission condition and the terminal state meets a second preset state condition, determining that the terminal moves.

That is, the condition for determining whether the terminal moves may further include state information of the terminal itself in addition to the reception quality. The terminal status may be measured by a global positioning system GPS built in the terminal, and then it is determined whether the terminal is moving.

Step 25: and when the first BPL is blocked or the terminal is rotated or the terminal is moved, determining that the BPL of the transmission channel is invalid.

And determining that the BPL of the transmission channel is invalid when any one of the first BPL blocking, the terminal rotation or the terminal movement is determined to occur.

In addition to the above steps 21 to 25, step 11 may also generate a corresponding request message without determining the failure event, specifically including: acquiring the receiving quality of a reference signal corresponding to a first BPL used by a transmission channel between network equipment; and when the receiving quality of the reference signal meets a fourth preset transmission condition, generating a request message of a BPL switching event of the transmission channel. The reference signal comprises a BPL training reference signal RS corresponding to the first BPL and/or a demodulation reference signal DMRS corresponding to the first BPL. The fourth preset transmission condition is similar to the first preset transmission condition, the second preset transmission condition and the third preset transmission condition, but the corresponding threshold values are different. For example: and the terminal UE measures whether the quality of the DMRS associated with the control channel and the data channel is lower than a seventh DMRS quality threshold, or whether the change rate of the DMRS quality exceeds a fourth DMRS change rate threshold, or whether the quality of the DMRS is lower than an eighth DMRS quality threshold and lasts for a fourth preset time.

The above embodiment describes the information transmission method of the present invention from the terminal side, and the following embodiment further describes the information transmission method of the network device side with reference to the drawings.

As shown in fig. 6, according to still another aspect of the embodiments of the present invention, there is further provided an information transmission method applied to a network device side, including the following steps:

step 61: and receiving a request message of the BPL recovery event of the transmission channel sent by the terminal.

The request message is sent after the terminal determines that a first transceiving beam pair link BPL used by a transmission channel between the terminal and the network equipment meets a preset transmission condition. Wherein the transmission channel includes control channel and/or data information, the first BPL may be one BPL or a plurality of BPLs. Taking the data channel as an example, the terminal can know some conditions occurring in the data channel in real time by monitoring the data channel, for example: when the BPL used by the NR-PDSCH is blocked, which may cause abnormal transmission of data information, or when the BPL quality of the data channel is degraded due to rotation or movement of the terminal, which may cause abnormal transmission of data information, generation of a corresponding request message may be triggered. The monitoring of the control channel is similar to the monitoring of the data channel, and therefore is not described herein.

Specifically, in order to ensure timeliness of reporting the request message, step 61 may be implemented by: and receiving the acknowledgement or non-acknowledgement ACK/NACK information sent by the terminal. Wherein, the ACK/NACK information also carries a request message of a BPL recovery event of the data channel. The ACK/NACK information fed back to the network device by the terminal is always enhanced ACK/NACK information, and the network device detects the enhanced ACK/NACK information to obtain a request message of a BPL recovery event sent by the terminal when monitoring that the transmission channel needs BPL recovery.

Before receiving the ACK/NACK information sent by the terminal, the method further includes: and determining whether the indication information used for indicating the terminal to adopt the response or non-response ACK/NACK information to carry the request message according to the information quantity of the information to be transmitted or the performance of the current transmission channel, and sending the indication information to the terminal. Specifically, when the network equipment judges that beam blocking possibly occurs, the terminal is configured through downlink signaling to perform feedback by using enhanced ACK/NACK information, and then the terminal reports the generated request information to the network equipment by using the enhanced ACK/NACK information after BPL (Business Process language) fails; otherwise, the network equipment configures the terminal to feed back the standard ACK/NACK information through the downlink signaling. It is worth pointing out that in this scenario, the network device can correctly detect the ACK/NACK information without blind detection of the ACK/NACK information.

On the other hand, when the network device does not instruct the terminal to feed back the ACK/NACK information, the network device needs to perform blind detection on the received ACK/NACK information in order to determine whether the received ACK/NACK information is standard ACK/NACK information or enhanced ACK/NACK information. Specifically, step 61 further includes: receiving response or non-response ACK/NACK information sent by a terminal after the request message is generated; and carrying out blind detection on the received response or non-response ACK/NACK information, and determining whether the response or non-response ACK/NACK information carries a request message of a BPL recovery event of a transmission channel. That is, the terminal determines whether to employ standard acknowledgement or non-acknowledgement ACK/NACK information feedback or enhanced ACK/NACK information feedback according to whether the request message is generated. Specifically, after generating a request message of a BPL recovery event, the terminal autonomously adopts enhanced ACK/NACK information to carry the request message and reports the request message to the network equipment, and the network equipment detects the enhanced ACK/NACK information in a blind detection mode and the like so as to obtain the request message of the BPL recovery event carried by the enhanced ACK/NACK information; when the terminal does not generate the request message of the BPL recovery event, the terminal autonomously feeds back standard ACK/NACK information to the network equipment, and the network equipment detects the standard ACK/NACK information in a blind detection mode and the like to obtain a transmission result of corresponding information.

Specifically, the event state can be increased along with the reporting of the ACK/NACK by increasing the bit number of the ACK/NACK information. Specifically, a new indication field may be added to the original ACK/NACK, or the enhanced ACK/NACK may be uniformly encoded while carrying ACK/NACK information and a request message. The base station can allocate the time-frequency resource of the existing ACK/NACK for the enhanced ACK/NACK, and because the ACK/NACK carries the request message, the total bit number is increased, and the coding rate of the time-frequency resource of the existing ACK/NACK needs to be reduced when the time-frequency resource of the existing ACK/NACK is adopted for transmission. Further, besides the transmission mode, the coding rate of the existing ACK/NACK can be kept, the base station carries out resource allocation according to the quantity of the enhanced ACK/NACK, and more time-frequency resources are allocated to the enhanced ACK/NACK when the data quantity of the enhanced ACK/NACK is large.

Furthermore, step 61 may also be implemented by: receiving a preset notification message sent by a terminal through a pre-allocated first time-frequency resource; and determining a request message of the BPL recovery event of the corresponding transmission channel according to the preset notification message. In this way, a dedicated event reporting notification message is adopted, and a first request message for triggering a beam switching event or a second request message for triggering a beam training event is sent on a predefined second time-frequency resource, which has no relation with ACK/NACK, for example, a similar RACH mechanism may be adopted.

Step 62: a new second BPL is determined for the transport channel based on the request message.

Wherein, step 62 specifically includes: when the request message is a first request message of a beam switching event, a switching target BPL is determined for the transmission channel. Wherein the handover target BPL is one of the BPLs in which no blocking occurs. Or when the request message is a second request message of the beam training event, performing beam training according to a recommended training mode to obtain a new BPL. Wherein the new BPL is the BPL with the best quality except the first BPL in the beam training.

Specifically, after receiving a first request message sent by the terminal, the network device receives a notification message triggering a beam switching event. At this time, if the switching target BPL simultaneously transmitted by the terminal is further received, the terminal is switched to the target BPL to transmit data. Or if the BPL information which is blocked is received, switching to other reported BPLs which are not blocked to send data.

And the network equipment starts the beam training process after receiving a second request message sent by the terminal, namely after receiving a notification message triggering a beam switching event. If the blocked BPL information is further received at this time, the blocked BPL may be removed from the trained beam. Or, if the recommended training mode information of the beam training is further received, the beam training is performed according to the recommended training mode to quickly determine a new BPL to transmit information. For example

When the BPL of the transmission channel fails because blocking occurs, a P1, P2 or P3 mode can be recommended; when the terminal rotates, P3 can be preferentially recommended; when the terminal moves, a P1, P2 or P3 mode may be recommended.

Further, when the request message is the first request message of the beam switching event, before step 62, the method further includes: receiving updated Channel State Information (CSI) sent by a terminal after the first BPL is determined to be blocked; and carrying out information transmission configuration according to the updated CSI. Wherein, the updated CSI is determined by the terminal according to the last beam training or beam measurement to determine the target BPL information for switching the transmission channel. After receiving the updated CSI reported by the terminal, the network device may perform channel configuration according to the updated CSI, thereby implementing fast recovery information transmission.

And step 63: and recovering information transmission between the terminal and the terminal through the second BPL.

When the receiving terminal monitors the transmission quality of the first BPL adopted by the transmission channel to determine that the BPL of the transmission channel is invalid, the receiving terminal further monitors request information of BPL recovery events sent by other BPL conditions, and further determines the most appropriate BPL recovery strategy according to the request information and the terminal, so that the BPL is quickly recovered, information can be transmitted through the new BPL, and the continuity of information transmission is ensured.

After receiving the request message sent by the terminal, the network device of the embodiment of the invention determines the new BPL according to the request message after the transmission channel with BPL failure occurs, so as to realize the recovery of the BPL of the transmission channel and ensure the continuity of information transmission.
