example 1

[0189] Example 1, for terminal-to-network relay, when RLF or beam failure occurs on the Uu link

[0190] The relay UE (relay terminal) determines which of the following states it is in: trying to restore the Uu link, performing cell reselection, unable to access the network; or the relay UE directly sends indication information.

[0191] When the relay UE is trying to restore the Uu link, it may not send any indication information to the remote UE (relayed terminal), or send the first indication information to the remote UE, and the first indication information includes the status information of the relay terminal; or,

[0192] When the relay UE performs cell reselection, send second indication information to the remote UE, where the second indication information includes status information of the relay terminal; or,

[0193] When the relay UE cannot access the network, send third indication information to the remote UE, where the third indication information includes status ...

[0199] Example 2, for terminal-to-network relay, when RLF or beam failure occurs on the SL link (direct communication link)

[0200] The relay UE determines which of the following states it is in: trying to restore the SL link with the remote UE, unable to restore the connection with the remote UE; or the relay UE directly sends indication information;

[0201] When the relay UE is trying to restore the SL link with the remote UE, it may not send any indication information to the network device, or send fourth indication information to the network device, the fourth indication information includes the indication information type, and the ID of the remote UE information; or,

[0202] When the relay UE cannot restore the connection with the remote UE, send fifth indication information to the network device, where the fifth indication information includes the indication information type and the ID information of the remote UE; or,

[0203] The relay UE directly sends the indicat...

[0207] Example 3, for end-to-end relay, RLF or beam failure occurs on the direct communication link

[0208] The relay UE determines which of the following states it is in: trying to restore the SL link with remote UE1, unable to restore the connection with remote UE1, trying to restore the SL link with remote UE2, and unable to restore the connection with remote UE2; or the relay UE directly sends Instructions.

[0209] When the relay UE is trying to restore the SL link with the remote UE1, it may not send any indication information to the remote UE2, or send the sixth indication information to the remote UE2, the sixth indication information includes the indication information type, and the ID of the remote UE1 information; or,

[0210] When the relay UE is trying to restore the SL link with the remote UE2, it may not send any indication information to the remote UE1, or send the seventh indication information to the remote UE1, the seventh indication information includes t...

Abstract

The embodiment of the invention provides a link failure processing method and device, a relay terminal and communication equipment. The method comprises the following steps: transmitting target information through a second link between the relay terminal and second equipment under the condition that a wireless link failure or a beam failure occurs in a first link between the relay terminal and first equipment; wherein the target information is used for indicating that the first link has a wireless link failure or a beam failure. According to the embodiment of the invention, when the relay terminal determines that the wireless link failure or the beam failure occurs in the first link, the relay terminal notifies the relayed terminal or the network equipment through the second link, so that the relayed terminal or the network equipment can know that the RLF or the beam failure occurs in the other link of the relay, thereby executing the corresponding operation.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a link failure processing method, device, relay terminal and communication equipment. Background technique [0002] The traditional wireless communication adopts the cellular network communication mode, that is, the terminal and the network side equipment transmit uplink and downlink data or control information through the Uu interface. [0003] Direct communication refers to a method in which adjacent terminals can perform data transmission through a direct communication link (also called Sidelink or PC5) within a short distance. The wireless interface corresponding to the Sidelink link is called a direct communication interface (also called a Sidelink interface or a PC5 interface). [0004] For the existing 5G Uu interface, when the link between the terminal and the network is interrupted, the terminal determines that a radio link failure (Radio Link Fai...
