Detailed ways

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

As shown in FIG. 2, an embodiment of the present invention provides a method for reporting beam failure information, which is applied to a terminal, and the method includes:

Step 21, the terminal receives the first reference signal set sent by the first transmission and reception point TRP;

Step 22: According to the reception quality of the reference signals in the first reference signal set, when it is determined that the link quality is lower than the first preset threshold, the terminal reports first information, where the first information is used to indicate beam failure related information .

In this embodiment of the present invention, the terminal receives the first reference signal set sent by the first transmission and reception point TRP; according to the reception quality of the reference signals in the first reference signal set, it is determined that the link quality is lower than the first preset threshold When , the terminal reports first information, where the first information is used to indicate beam failure related information. The problem of partial beam failure recovery of multi-TRP is solved, which is beneficial to improve the transmission rate or reliability.

In an optional embodiment of the present invention, in step 22, when it is determined that the link quality is lower than the first preset threshold, the terminal reports the first information, which may include:

When it is determined that the link quality is lower than the first preset threshold within a preset time, the terminal reports the first information.

In this embodiment, the method for the terminal to determine that a beam failure occurs in a certain TRP may be: for example, in the first reference signal set of the first TRP within a preset time, there are times that the reception quality of some or all of the reference signals is lower than the threshold X. More than or equal to M times, it is considered that the link quality between the TRP and the terminal is lower than the first preset threshold, and the TRP has a beam failure.

In the above-mentioned optional embodiment of the present invention, the terminal reporting the first information may include:

The terminal reports the first information through uplink resources configured by the network device for the second transmission and reception point TRP.

When a beam failure occurs in the first TRP, the network side needs to be notified to perform beam failure recovery. At this time, the first information can be reported through the uplink resources configured by the network device for the second transmission and reception point TRP. The second TRP here is a TRP having a communication link with the terminal. The first TRP, the second TRP, and at least one other TRP form a multi-TRP (multi-TRP) scenario, and these TRPs can be connected to the terminal for communication.

In the above-mentioned optional embodiment of the present invention, the first information is reported through the uplink resources configured by the network device for the second transmission and reception point TRP, including:

1-bit information is reported through the physical uplink control channel PUCCH configured by the network device for the second transmission and reception point TRP. The 1-bit information is used to indicate beam failure related information.

In this embodiment, the network device configures PUCCH resources, and the PUCCH resources carry 1-bit information. When beam failure occurs in the first TRP, the 1-bit information is sent on the PUCCH of other TRPs.

As shown in FIG. 1 , the base station configures the first reference signal set for detecting whether a beam failure occurs in TRP 1 (the first TRP). Of course, the base station can also configure another reference signal set to detect whether a beam failure occurs in TRP2 (second TRP). When a beam failure occurs in the reference signal of the first reference signal set, the terminal sends 1 bit of information on the PUCCH resource of TRP 2 . The base station only needs to perform energy detection to know whether a beam failure has occurred in TRP 2/TPR 1. If it is detected that information is sent on the PUCCH resource of TRP2, the network side can initiate a beam management process, the terminal reports beam measurement results, and searches for communicable beams from the beams of TRP1.

In the above-mentioned optional embodiment of the present invention, reporting the first information through the uplink resources configured by the network device for the second transmission and reception point TRP may include:

If the terminal is configured with a second reference signal set for identifying the candidate beam of the first transmission and reception point TRP and there is a reference signal whose quality is greater than or equal to a second preset threshold in the second reference signal set, Report 1-bit information through the physical uplink control channel PUCCH configured by the network device for the second transmission and reception point TRP, where the 1-bit information is the first value; or,

If the terminal is not configured with a second reference signal set for identifying the candidate beam of the first transmission and reception point TRP or is configured with a second reference signal for identifying the candidate beam of the first transmission and reception point TRP When there is no reference signal whose quality is greater than or equal to the second preset threshold in the second reference signal set, report 1-bit information through the physical uplink control channel PUCCH configured by the network device for the second transmission and reception point TRP , the 1-bit information is the second value.

Here, the reference signal in the second reference signal set may be the reference signal received power RSRP, or may be the signal-to-noise ratio SNR or the signal-to-interference and noise ratio SINR of the reference signal.

Wherein, when the 1-bit information is the first value, the above method may further include:

The terminal sends, on the physical uplink shared channel PUSCH scheduled by the network device for the second transmission and reception point TRP, an identifier of a reference signal in the second reference signal set whose quality is greater than or equal to the second preset threshold.

In this embodiment, the network device configures a dedicated PUCCH resource for the TRP, and the PUCCH resource carries 1 bit of information. When a beam failure occurs in the first TRP and an alternative beam is found, the 1 bit is sent on the PUCCH of other TRPs, such as "1"; when a beam failure occurs in the first TRP and no alternative beam is found, it is sent on the PUCCH of other TRPs Send this 1bit, such as "0". The base station can perform resource scheduling or initiate a beam management process according to the received 1-bit information. If the base station schedules the PUSCH, the terminal can report the candidate reference signal identifier on the scheduled PUSCH resource.

As shown in FIG. 1 , the base station configures a first reference signal set for detecting whether a beam failure occurs in TRP 1, and the base station configures a third reference signal set for detecting whether a beam failure occurs in TRP 2. The base station configures the second reference signal set for identifying candidate reference signals of TRP 1, and the base station configures the fourth reference signal set for identifying candidate reference signals for TRP 2.

When the reference signal reception quality of the first reference signal set satisfies the beam failure condition and there is a reference signal whose reception quality meets the candidate reference signal condition in the second reference signal set, the terminal sends 1-bit information "1" on the PUCCH resource of TRP 2 ";

When the received quality of the reference signals of the first reference signal set satisfies the beam failure condition but the quality of no reference signal in the second reference signal set satisfies the condition of the candidate reference signal, the terminal sends 1-bit information "0" on the PUCCH resource of TRP 2 ".

If the network side decodes that the terminal sends "1" on the TRP2 resource, the network side can schedule the PUSCH resource, and the terminal sends the TRP1 candidate beam reference signal identifier on the scheduled PUSCH resource. If the network side decodes that the terminal sends "0" on the TRP2 resource, the network side can initiate a beam management process, the terminal reports the beam measurement result, and searches for a communicable beam from the TRP1 beam.

In the above-mentioned optional embodiment of the present invention, reporting the first information through the uplink resources configured by the network device for the second transmission and reception point TRP may include:

If the terminal is configured with a second reference signal set for identifying the candidate beam of the first transmission and reception point TRP and there is a reference signal whose quality is greater than or equal to a second preset threshold in the second reference signal set, On the physical uplink shared channel PUSCH scheduled by the network device for the second transmission and reception point TRP, the identifier of the reference signal in the second reference signal set is reported through the media medium control unit MAC CE; or,

If the terminal is not configured with a second reference signal set for identifying the candidate beam of the first transmission and reception point TRP or is configured with a second reference signal for identifying the candidate beam of the first transmission and reception point TRP When there is no reference signal whose quality is greater than or equal to the second preset threshold in the second reference signal set, on the physical uplink shared channel PUSCH scheduled by the network device for the second transmission and reception point TRP, through the media medium control control The unit MAC CE reports the identifier of the reference signal in the preset target reference set.

The PUSCH here is requested by the terminal through the physical uplink control channel PUCCH of the second transmission and reception point TRP, and is scheduled by the network device.

In this embodiment, after a beam failure occurs, the terminal reports the first information, the first information is carried by the MAC-CE and sent on the PUSCH, and the first information at least includes the identifier of the candidate reference signal. The PUSCH resource may be requested by the terminal from the base station. Optionally, the terminal requests PUSCH resources through dedicated PUCCH resources. When a beam failure occurs in the first TRP, the terminal sends the above information on the PUCCH and/or PUSCH of other TRPs.

As shown in FIG. 1 , the base station configures a first reference signal set for detecting whether a beam failure occurs in TRP 1, and the base station configures a third reference signal set for detecting whether a beam failure occurs in TRP 2. The base station configures the second reference signal set to identify the candidate reference signals of TRP 1, and the base station configures the fourth reference signal set to identify the candidate reference signals of TRP 2. When the reference signal of the first reference signal set has a beam failure, the terminal sends the candidate reference signal identifier through the MAC-CE on the PUSCH resource of TRP 2, and the reference signal indicated by the candidate reference signal identifier is the reference signal in the second reference signal set. reference signal.

If the terminal does not have available PUSCH resources, the terminal first sends a scheduling request on the PUCCH of TRP2, the base station allocates PUSCH resources to the terminal after receiving the scheduling request, and the terminal sends MAC-CE on the PUSCH resources allocated by the base station. When the terminal does not find a candidate reference signal, it reports a special reference signal identifier (Reserved bits) on the MAC-CE.
