Embodiment 2

[0067] further reference Figure 5 , as for the above figure 2 For the realization of the method shown, this application provides an embodiment of a V2X protocol reducing relay node selection system, the system embodiment is the same as figure 2 Corresponding to the illustrated method embodiments, the system can be specifically applied to various electronic devices.

[0068] Such as Figure 5 As shown, the V2X protocol reduction relay node selection system 500 of this embodiment includes: a sending end UE501, a neighboring cell end UE502 communicating with the sending end UE501, and a receiving end UE503 that is not covered by the sending end UE; where:

[0069] The sending end UE501 is configured to send a broadcast message to all neighboring cell UEs 502 within the coverage when the sending end UE501 needs to send a broadcast message to the receiving end UE503 not within the coverage of the sending end UE501 according to the relay end UE;

[0070] The adjacent cell term...

Abstract

The embodiment of the invention belongs to the technical field of wireless communication, and relates to a V2X protocol reduced relay node selection method, a system, equipment, and a medium. According to the invention, when a sending end UE needs to send a broadcast message to a receiving end UE which is not in the coverage range of the sending end UE, the adjacent cell end UE in the coverage range screens the respective adjacent cell end UE according to the respective channel quality and a preset channel quality threshold value, thereby obtaining the initial relay end UE with higher channel quality. The initial relay terminal UE sends broadcast information to the receiving terminal UE through the initial relay terminal UE, the receiving terminal UE performs target screening on the initial relay terminal UE after receiving the broadcast information to obtain target relay terminal UE which is finally used for establishing communication connection between the sending terminal UE and the receiving terminal UE, and secondary screening is performed on the adjacent cell terminal UE, so that the number of times of broadcasting messages to potential relay UE is reduced. the relay node decides whether to send the broadcast message to the receiving node or not according to the channel condition, so that the invalid broadcast message is effectively screened. The system performance is further improved.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a V2X protocol reduction relay node selection method, system, device and medium. Background technique [0002] The V2X protocol is a standard technology proposed by 3GPP for the vehicle network in the URLLC scenario. When two UEs want to send data, but the receiving UE is not within the coverage of the sending UE, a relay UE is needed to transmit the sending UE data. Relay, and then the relay UE sends the data of the sending UE to the receiving UE, so that the receiving UE can receive the data correctly. [0003] However, the applicant found that UE1 broadcasts the Direct Communication Request message to the relay UE, and each relay UE broadcasts the Direct Communication Request message to UE2 after receiving the message. At this time, if a large number of nodes are selected as relay UEs, UE2 A large number of Direct Communication Request messages wi...
