Embodiment three:
In order to make it easy to understand, below the present embodiment with Sidelink unicast communication during, the selection of beam direction, reconfiguration
And the example that reverts to of beam failure is illustrated.
One: Sidelink unicast communication beam direction selection of example
For V2X sidelink unicast communication, between unicast communication UE resource distribution can based on the direction associated beam beam into
Row configuration can consider to carry out sidelink unicast communication on the preferable direction beam of beam mass of measurement.When UE is to choosing
It selects the direction beam and carries out unicast communication, since UE is constantly in relative-movement state, after a period of time, which may matter
Quantitative change is poor, it is therefore desirable to carry out beam failure recovery and select new beam, and be switched on new beam continue into
Row sidelink unicast communication, to guarantee the continuity of service.

The direction beam or multiple beam mass preferably in select a direction beam, send PC5 connection establishment response message.
Under Model B sidelink discovery mode, it is assumed that the UE1 in Fig. 1 is obtained on initial SL BWP
After taking sidelink discovery resource, by beam sweeping mode in all directions or selection at one or more
A side beam sends up sidelink discovery solicitation (i.e. straight-through link discovery request) message.UE2 exists
It listens in the direction beam of sidelink discovery request message of UE1, selects the top-quality direction beam beam or more
A beam mass is preferably middle to select a direction beam, sends sidelink and finds response message, and the direction the beam conduct
The direction sidelink unicast communication beam between UE.The sidelink that UE1 receives UE2 has found response message, obtains sidelink
After the communication resource, UE1 and UE2 carry out PC5 connection establishment process on the selected direction beam, and it is mono- to carry out sidelink later
Broadcast communication.The process is shown in Figure 7, comprising:
S701:UE1 and UE2 obtains sidelink discovery resource;
S702:UE1 sends sidelink discovery solicitation message to UE2;
S703:UE2 selects beam mass most in the direction beam for the sidelink discovery request message for listening to UE1
The good direction beam selects a direction beam in multiple beam mass are preferable, sends sidelink and finds response message;
S704:UE1 and UR2 obtains the communication resource;
S705:UE1 and UE2 carries out PC5 connection foundation on the selected direction beam.
Example two: the reconfiguration of wave beam beam
In this example, lead directly to link beam Sidelink beam measurement, may also comprise but be not limited to it is following at least it

Optionally, after UE receives Sidelink beam failure recovery configuration information from opposite end UE, may be used also
Corresponding response or confirmation message are sent to opposite end UE.For example, a kind of Sidelink beam failure recovery configuration
The interactive process of information is shown in Figure 8, comprising:
S801:UE2 sends Sidelink beam failure recovery config to UE1;
S802:UE1 sends Sidelink beam failure recovery config ack to UE2.
Four: Sidelink beam failure recovery of example triggering
When UE (detects sidelink beam failure (the specific inspection of beam failure herein for the physical layer of source UE)
Above-mentioned beam quality detection mode can be used in survey mode, and other modes, such as packet loss etc. can also be used), SL is indicated to MAC
Beam failure instance starts or restarts the progress timing of beam failure detection timer, and MAC is counted
Instance number of SL beam failure plus 1;When beam failure detection timer expiry, MAC counts SL
Instance number of beam failure is set to 0;When SL beam failure instance instruction number reaches sidelink
The instance number of maximum beam failure configured in beam failure recovery configuration information, triggering
Sidelink beam failure recovery process.
The execution of five: Sidelink beam failure recovery of example
Mode one:
UE selects beam resource to send SL beam failure to opposite end UE (i.e. target UE) in candidate beam resource

Mode: 1) according to the beam quality threshold configured in Sidelink beam failure recovery configuration information, selection is waited
Beam mass is selected to be higher than the beam of the threshold value (i.e. default preferred mass threshold value) of configuration, it is full if there is multiple candidate beam
Sufficient condition, then UE can realize selection one;If 2) do not had in Sidelink beam failure recovery configuration information
Corresponding beam quality threshold is configured, then selects the highest beam of beam mass.
Optionally, in aforesaid way one, if UE is after sending SL beam failure recovery request message
The response message that (beam failure recovery request retransmission timer) does not receive opposite end UE in certain time, then retransmit
BFR request is not received yet if reaching maximum number of retransmissions (beam failure recovery request retransmits maximum times)
Response, then this time BFR failure;UE carries out beam gravity treatment and again attempts to BFR later.
Optionally, in aforesaid way one, if UE is after sending SL beam failure recovery request message
(beam failure restores timer) does not receive the response message of opposite end UE in certain time, then this beam

Discovery message, then in the preferably one or more sides beam of beam mass upwardly through PC5 signaling, such as beam
Switch/recovery signaling informs the new direction beam.Source UE is selected after receiving PC5beam switch/recovery signaling
It selects the direction beam and replys response message, then beam failure recovery success.New beam is used between two UE
Direction carries out sidelink unicast communication.
Mode four:
For Model B sidelink discovery mode, UE selection in source is sent up in one or more sides beam
Discovery solicitation message, in order to distinguish other not sent for beam failure recovery
Discovery message can be identified comprising beam recovery/switch/update in the discovery message, and be waited
To discovery response message.Beam of the opposite end UE (i.e. target) in the sidelink discovery request message for listening to UE
In direction, selects the top-quality direction beam beam or in multiple beam mass preferably one direction beam of middle selection, send
Sidelink has found response message.If source UE receives the discovery of opposite end UE on a wherein direction beam
Response message, then beam failure recovery success, source UE are carried out to being switched on the direction beam
Sidelink communication, and opposite end UE is also switched to carry out sidelink communication on the direction beam.
Optionally, in this mode, sidelink beam failure recovery can be used in source UE and target UE
The candidate beam resource of middle configuration sends Model B discovery solicitation/response message, thus not
The equal discovery period is needed, if receiving response, successfully, UE communication is to can switch by beam failure recovery
Sidelink communication is carried out on to the new direction beam, can promote the efficiency of beam failure recovery.
