Currently, the forward position and trend that scientific and technical innovation is merged with industry transformation are intelligent network coproduction industry, wherein car networking industry
Market is gradually flourishing.C-V2X is a kind of wireless communication solution developed for transportation industry, and the solution is to intelligent network
The universal of automatic Pilot in automobile and future has very important meaning.C-V2X is the proprietary protocol of car networking, towards car networking
Application scenarios, realize vehicle and vehicle (V2V), vehicle and trackside facility (V2I), vehicle and people (V2P), vehicle and network (V2N) interconnection and
Data transmission, is referred to as V2X, wherein core is the interconnection of V2V.For reply vehicle active safety, driving efficiency, car entertainment more
Scape business demand, two kinds of C-V2X use " wide area cellular+short distance through type ".As shown in Figure 1, the former is based on existing Uu interface,
I.e. V2X terminal is similar to regular handset terminal, carries out uplink and downlink communication with base station, mainly carries traditional car networking business, such as
Map downloading, entertainment information etc.；The latter introduces Sidelink link (similar to traditional uplink, downlink link), leads to
It crosses PC5 interface and realizes that V2V, V2I direct communication, vehicle active safety business mainly meet terminal security low time delay, Gao Ke
The requirement leaned on.When 5G V2X terminal is outside the 5G network coverage in the prior art, according to the mode of base station scheduling, 4G can only be passed through
The Sidelink resource of the Uu interface scheduling 4G of network, the V2X service message for carrying out 4G are sent.5G brings new business and enriches
Sidelink resource be not available, while for 5G enhancing Sidelink link technology can not also enjoy.According to covering
The mode of outer pre-configuration carries out 5G sidelink communication, then reliability cannot be guaranteed, while in the higher place of density, occurring
The probability of problem is larger, and network and the business for being not involved in car networking are unfavorable for the operation management and information processing of operator.Such as figure
Shown in 2, the direct communication based on PC5 can be realized a variety of car networking business, have the characteristics that time delay is lower, while PC5 can be with
Using the dedicated frequency spectrum of car networking, conventional wireless service resources are not take up, the communication based on PC5 can be divided into both of which again, both
The base station Mode3 scheduling method and Mode4 Ad hoc mode, the terminal of Mode3 mode is under Cellular Networks covering, when having message transmission
To base station requests resource, base station can indicate available resource to UE by DCI Format 5A according to occupation condition.It is existing
When 5G V2X terminal is outside the 5G network coverage in technology, according to the mode of base station scheduling, the Uu interface of 4G network can only be passed through
The Sidelink resource for dispatching 4G, the V2X service message for carrying out 4G are sent.5G brings new business and Sidelink abundant money
Source is not available, while can not be enjoyed for the Sidelink link technology of 5G enhancing yet.According to the outer side being pre-configured of covering
Formula carries out 5G sidelink communication, then reliability cannot be guaranteed, while in the higher place of density, the probability to go wrong compared with
Greatly, network and it is not involved in the business of car networking, is unfavorable for the operation management and information processing of operator.
