Description

Reporting method of beam failure recovery BFR, terminal and network side equipment

Technical Field

The present invention relates to the field of wireless technologies, and in particular, to a method, a terminal, and a network side device for reporting BFR for beam failure recovery.

Background

In an Evolved Long Term Evolution (LTE) system, a terminal physical layer performs quality monitoring on a current beam, and reports information (instance) of poor quality to a Media Access Control (MAC) layer. The MAC layer judges that the terminal enters the Beam failure recovery based on information such as a Beam Failure Recovery (BFR) threshold value configured by a high layer, starts a Beam failure recovery timer, informs a network side of the Beam failure recovery, and executes random access or packages BFR request information.

When Random Access is performed, procedures such as BFR non-Contention Random Access (CFRA) or BFR Contention Based Random Access (CBRA) are further triggered to enable selection of a new beam.

When a CFRA BFR is triggered, a CBRA BFR may need to be further triggered. The CFRA BFR needs to reserve a preamble index and/or an opportunity contention for Random Access (RA) for the beam, thereby causing a certain waste of Random Access resources. In addition, when the terminal executes BFR random access, the transmission data is interrupted, and normal data transmission cannot be carried out.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The method for reporting BFR for beam failure recovery according to the embodiments of the present invention is applied to a wireless communication system, which may be a 5G system, an Evolved Long Term Evolution (lte) system, or a subsequent Evolved communication system. Fig. 1 is a schematic structural diagram of a wireless communication system according to an embodiment of the present invention. As shown in fig. 1, the wireless communication system may include: the base station 10 and user equipment (or terminals), such as terminals, are denoted as UE 20, and the UE 20 may be connected to the base station 10. In practical applications, the connections between the above devices may be wireless connections, and fig. 1 illustrates the connections between the devices by solid lines for convenience and convenience in visual representation.

The base station 10 provided in the embodiment of the present invention may be a commonly used base station, may also be an evolved node base station (eNB), and may also be a network side device (for example, a next generation base station (gNB) or a Transmission and Reception Point (TRP)) in a 5G system, or a cell, and the like.

The user equipment provided by the embodiment of the invention can be a Mobile phone, a tablet Computer, a notebook Computer, an Ultra-Mobile Personal Computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like.

In order to solve the problems that resource waste and normal data transmission cannot be performed when a terminal beam fails to recover and a BFR random access is triggered in the prior art, an embodiment of the present invention provides a method for reporting a BFR for a beam failure recovery, where before a BFR threshold (a first threshold condition) decision based on a high-level configuration enters the BFR, a media access Control MAC Control unit (Control Element, CE) sends a BFR request to a network side device, and reports a candidate beam with a good beam quality, so as to avoid the problems that the BFR random access is triggered, the resource waste is caused, and normal data transmission cannot be performed.

The first implementation manner of the method for reporting BFR for beam failure recovery according to the embodiment of the present invention is applied to a terminal, and as shown in fig. 2, the method includes:

s210, when detecting that the quality of the current beam is higher than a first threshold condition for performing BFR (bidirectional Forwarding) recovery after beam failure and lower than or equal to a preset second threshold condition, sending a BFR request to network side equipment through a Media Access Control (MAC) control unit (CE);

In this embodiment of the present invention, the first threshold condition is determined by a high-level configuration, and the second threshold condition is determined by the terminal.

Specifically, in the process of monitoring the beam quality, when the terminal determines that the current beam quality is lower than or equal to a preset second threshold condition before judging that the current beam quality reaches a first threshold condition which needs to perform a BFR request configured by a high layer, the terminal triggers in advance to report the BFR request to a network side device.

The determination of the second threshold condition and the algorithm for the terminal to determine the second threshold condition are not specifically limited in the present invention, as long as the quality of the beam meeting the second threshold condition is higher than the quality of the beam meeting the first threshold condition, and it is ensured that the terminal triggers the report of the BFR request to the network side device in advance before determining that the current beam quality reaches the first threshold condition that the high-level configuration needs to perform the BFR request.

In this embodiment of the present invention, optionally, in step S210, when the media access control MAC control element CE sends a BFR request to the network side device, the method further includes:

a BFR timer is started and a beam failure event indication COUNTER (BFI _ COUNTER) is set to zero.

By starting the BFR timer, the terminal can monitor whether the response of the network side equipment to the BFR request is received or not within the timing time of the BFR timer; and setting the BFI _ COUNTER to zero, so that when the terminal does not receive the response of the network side equipment to the BFR request within the timing time of the BFR timer, the terminal retransmits the BFR request, counts the BFR request, and when the maximum transmission frequency configured by a high layer is reached, the beam fault recovery is considered to be failed.

In this embodiment of the present invention, in step S210, in the step of sending the BFR request to the network side device through the media access control MAC control element CE, sending of the BFR request is indicated by a reserved uplink channel identity (LCID).

Table 1 below is a table of correspondence between LCID values and indices for an Uplink Shared Channel (UL-SCH). In the embodiment of the present invention, the BFR request may be represented by an LCID with a reserved index of 51, but the present invention is not limited thereto.

TABLE 1

In addition, optionally, in step S210, in the step of sending, by the media access control MAC control element CE, a BFR request to the network side device, each data unit of the media access control MAC control element CE includes: reserved bits, an extended field and reference signal index (RS index) information;

wherein the extended field is used for indicating whether other data units located behind the current data unit further include reference signal index information; the reference signal index information is used to indicate an index of one candidate beam in a pre-configured candidate beam list.

Specifically, the MAC CE used to send the BFR request is illustrated in fig. 3, for example. Wherein in each data unit, the R bit is a reserved bit; e is an extended field, wherein when the extended field is 1, the other data units after the current data unit further include Reference Signal (RS) index information; when the extended field is 0, it indicates that other data units following the current data unit do not include reference signal index RS index information.

In addition, it is understood that the candidate Beam List candidate Beam RS List may be pre-configured by Radio Resource Control (RRC).

Alternatively, the reference signal index RS index information indicates an index of one candidate beam in the pre-configured candidate beam list in the form of a bitmap format.

Specifically, for example, the RS index information indicates whether the RS index is valid by 1bit Bi (Bi ═ 0 "or" 1 "), and Bi identifies the ith RS index in the candidate Beam List candidate Beam RS List configured by RRC. For example, the candidate Beam RS List has 16 RS indexes, and the reference signal index information is represented by a bitmap format as shown in fig. 4. Whether the ith RS index is a valid candidate beam can be found from Bi being "1" or "0".

Of course, the representation of the reference signal index information is not limited to be capable of adopting only the above form, and those skilled in the art should be capable of representing the reference signal index information in various forms, which are not illustrated one by one herein.

Furthermore, in this embodiment of the present invention, optionally, in step S210, in the step of sending, by the MAC control element CE, the BFR request to the network side device, the sending priority of the BFR request is higher than that of data other than the cell radio network temporary identifier (C-RNTI) MAC CE and the data sent by the Uplink (UL) Common Control Channel (CCCH).

That is, the BFR MAC CE transmission is prioritized after C-RNTI MAC CE and after data is transmitted by the UL-CCCH, before other data. Therefore, when the terminal detects that the current beam quality is poor, the terminal can report the BFR request to the network side equipment preferentially, and the terminal can report the beam with good quality obtained by the measurement of the terminal, inform the network side equipment and accurately replace the beam.

By adopting the BFR reporting method of the embodiment of the invention, before the BFR threshold (first threshold condition) based on high-level configuration is judged to enter the BFR, the BFR request is sent to the network side equipment in advance, and the candidate beam with better beam quality is reported to inform the network side equipment and accurately change the beam, so that the problems of resource waste and incapability of normal data transmission caused by triggering BFR random access by the BFR are avoided.

A second implementation of the method for reporting a BFR according to the embodiment of the present invention is applied to a network side device, and as shown in fig. 5, the method includes:

In the method for reporting BFR recovery due to beam failure according to the embodiment of the present invention, before a terminal determines to enter a BFR based on a BFR threshold (a first threshold condition) configured by a high layer and when a beam quality is lower than or equal to a preset second threshold condition, a media access Control MAC Control unit (Control Element, CE) sends a BFR request to a network side device, and reports a candidate beam with better beam quality, so that the network side device learns that the beam quality of the terminal is poor and the beam is accurately changed, thereby avoiding the problems that when the beam quality of the terminal is poor, a BFR random access is triggered, so that resources are wasted and normal data transmission cannot be performed.

Optionally, after step S510, the method further includes:

and sending a response message to the BFR request to the terminal.

Specifically, after receiving the BFR request, the network side device may switch the beam to the candidate beam reported by the BFR request, and send a response message to the BFR request to the terminal through the switched candidate beam, so as to confirm the candidate beam reported by the BFR request to the terminal, and complete recovery of beam failure, so as to avoid resource waste and failure of normal data transmission due to further triggering of BFR random access by the terminal.

Optionally, in step S510, in the step of acquiring the BFR request sent by the terminal to the network side device through the media access control MAC control element CE, the BFR request is represented by a reserved uplink logical channel identifier LCID.

See table 1 for a correspondence table between LCID values and indices for Uplink Shared Channel (UL-SCH). In the embodiment of the present invention, the BFR request may be represented by an LCID with a reserved index of 51, but the present invention is not limited thereto.

In addition, optionally, in step S510, in the step of acquiring a BFR request sent by the terminal to the network side device through the media access control MAC control unit CE, each data unit of the media access control MAC control unit CE includes: reserved bits, an extended field and reference signal index information;

For example, the RS index information indicates whether the RS index is valid by 1bit Bi (Bi ═ 0 "or" 1 "), and Bi identifies the ith RS index in the candidate Beam List candidate Beam RS List configured by RRC. Taking the candidateBeam RS List with 16 RS indexes as an example, the reference signal index information is represented by bitmap format as shown in fig. 4. Whether the ith RS index is a valid candidate beam can be found from Bi being "1" or "0".

Optionally, in step S510, in the step of acquiring a BFR request sent by the terminal to the network side device through the media access control MAC control element CE, the priority sent by the BFR request is higher than data other than the cell radio network temporary identifier C-RNTIMAC CE and data sent by the uplink common control channel UL-CCCH.
