CROSS-REFERENCE TO RELATED APPLICATIONS

This application is based on the Chinese patent application with the application number of 202011094957.9 and the filing date of October 14, 2020, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby incorporated by reference into this application.

technical field

The present application relates to the field of communication technologies, and in particular, to a method for reporting and receiving beam failure information, a terminal and a network device.

Background technique

The beam failure recovery process generally includes: 1) the terminal fails to detect the beam; 2) the terminal identifies the alternative beam; 3) the terminal sends a beam recovery request (BFRQ, Beam Failure Recovery Request) to the base station; 4) The terminal monitors the response of the base station to the BFRQ.

The manner in which the terminal fails to detect the beam is: the terminal detects the quality of the reference signal in the reference signal _set q0, where q0 is configured by the base station or according to the transmission configuration indicator state (TCI-state, Transmission Configuration Indicator- state) is determined. When the quality of all reference signals in q ⁰ is lower than Qout,LR, a beam failure instance is counted, and when the number of beam failure instances exceeds a defined number of times within a certain period of time, it is determined that beam failure has occurred. The terminal identifies the candidate beam by selecting a reference signal (RS, Reference Signal) whose reference signal received power (RSRP, Reference Signal Receiving Power) is greater than or equal to Qin, LR in the reference signal set ^q1 .

In the multi-TRP (multi-Transmission Receive Point) technology, that is, the terminal can establish a communication link with multiple TRPs for data transmission, and multiple TRPs can improve the transmission efficiency by sending the same or different data. reliability or transfer rate.

As shown in Figure 1, assuming that TRP1 and TRP2 belong to the same cell, according to the existing beam failure detection mechanism, the base station configures the reference signal set ^q ₀ for detecting the link quality of TRP1 and TRP2, when the quality of all reference signals in ^q ₀ is are all lower than Qout, and only one beam failure example will be counted when LR is used.

However, in the multi-TRP scenario, it may happen that the link between the terminal and a certain TRP is blocked. As shown in Figure 1, TRP1 cannot communicate with the terminal, and TRP2 still maintains communication with the terminal. Called partial beam failure. However, in the current solution, there is no resolution mechanism for the case of partial beam failure.

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 application 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 application will be more thoroughly understood, and will fully convey the scope of the application to those skilled in the art.

As shown in FIG. 2 , an embodiment of the present application 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 TRP;

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

In this embodiment of the present application, the terminal receives the first reference signal set sent by the first TRP; according to the received 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 first reference signal set is sent 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 application, in step 22, when it is determined that the link quality is lower than the first preset threshold, sending the first information may include: determining that the link quality is lower than the When the first preset threshold is reached, the first information is sent.

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

In the above-mentioned optional embodiment of the present application, the above-mentioned sending the first information may include: the terminal sends the first information through uplink resources configured for the second TRP by the network device.

When a beam failure occurs in the first TRP, the network device 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 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 application, sending the first information using the uplink resources configured for the second TRP through the network device includes: sending the PUCCH configured for the second TRP through the network device, including sending the first information. The 1-bit (bit) information of the information, that is, the 1-bit information is used to indicate beam failure related information.

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

For example, in the example shown in FIG. 1 , the base station configures the first reference signal set to detect 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 beam failure occurs in TRP2 (second TRP). When 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 application, the above-mentioned sending the first information through the uplink resource configured for the second TRP by the network device may include: if the terminal is configured with an alternative for identifying the first TRP When the second reference signal set of the beam and the second reference signal set have reference signals whose quality is greater than or equal to the second preset threshold, 1-bit information is sent through the PUCCH configured by the network device for the second TRP, and the 1-bit information is sent. The bit information is the first value; or,

If the terminal is not configured with a second reference signal set for identifying candidate beams of the first TRP or is configured with a second reference signal set for identifying candidate beams of the first TRP, but the second When there is no reference signal whose quality is greater than or equal to the second preset threshold in the reference signal set, 1-bit information is sent through the PUCCH configured by the network device for the second TRP, and the 1-bit information is the second value.

Exemplarily, the reference signal in the second reference signal set may be RSRP, or may be a signal-to-noise ratio (SNR, Signal-to-Noise Ratio) or a signal-to-interference-plus-noise ratio (SINR, Signal to Interference ratio) of the reference signal. plus Noise Ratio).

In some optional embodiments, when the 1-bit information is the first value, the above method may further include: the terminal sends the quality in the second reference signal set on the PUSCH scheduled by the network device for the second TRP The identifier of the reference signal 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 information is sent on the PUCCH of other TRPs, for example, the bit of the 1-bit information is set to "1"; when the first TRP has a beam failure and no beam is found In the case of the alternative beam, the 1-bit information is sent on the PUCCH of other TRPs, for example, the bit of the 1-bit information is set to "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.

Referring to the example shown in FIG. 1 , the base station configures the 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 reception quality of the first reference signal set meets the beam failure condition, and there is a reference signal whose reception quality meets the alternative reference signal condition in the second reference signal set, the terminal sends 1-bit information on the PUCCH resource of TRP 2 " 1";

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

If the network device decodes that the terminal sends "1" on the resource of TRP2, the network device can schedule the PUSCH resource, and the terminal sends the candidate beam reference signal identifier of TRP1 on the scheduled PUSCH resource. If the network device decodes that the terminal sends "0" on the TRP2 resource, the network device 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 application, the above-mentioned sending the first information through the uplink resource configured for the second TRP by the network device may include: if the terminal is configured with an alternative for identifying the first TRP When the second reference signal set of the beam and the second reference signal set have reference signals whose quality is greater than or equal to the second preset threshold, on the PUSCH scheduled by the network device for the second TRP, report the second reference signal through the MAC CE. The identifier of the reference signal in the second reference signal set; or, if the terminal is not configured with a second reference signal set for identifying the candidate beam of the first TRP or is configured with an alternative beam for identifying the first 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 of the beam, the preset is reported through the MAC CE on the PUSCH scheduled by the network device for the second TRP. The identity of the reference signal in the target reference set.

In this embodiment, the PUSCH is requested by the terminal through the PUCCH of the second TRP, and is scheduled by the network device.

In this embodiment, after the 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.

Referring to the example shown in FIG. 1 , the base station configures the 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. Signal.

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