Method and wireless unit for v2x communication

Abstract

A system and apparatus are disclosed herein for vehicle to everything (V2X) wireless communication. A V2X wireless transmit/receive unit (WTRU) may receive a vehicle to everything (V2X) message including configuration information and a road side unit (RSU) address. The WTRU may then transmit a message to the RSU according to the configuration information including multimedia broadcast multicast services (MBMS) data. The configuration information may include a MBMS service descriptor. One or more of the V2X messages may include priority information, WTRU type information, or both.

1 . A method for use in a first wireless transmit/receive unit (WTRU), the method comprising:
 receiving configuration information related to a vehicle to everything (V2X) communication from a V2X Control Function, the configuration information comprising an associated User Service Description (USD) information;   using the USD, receiving a multimedia broadcast multicast service (MBMS) broadcast, wherein the broadcast contains an address of a V2X Application Server; and   transmitting a V2X message to the V2X Application Server using the address received via MBMS.   
     
     
         2 . The method of  claim 1 , wherein the configuration information further comprises one or more of: an access point name (APN) of a local network for V2X communication, a local gateway (LGW) address, a local home network (LHN) identity, relay node information, a road side unit (RSU) address, a temporary mobile group identity (TMGI), priority information or quality of service (QoS) parameters. 
     
     
         3 . The method of  claim 1 , wherein the V2X message includes ProSe Per-Packet Priority (PPPP) priority information. 
     
     
         4 . The method of  claim 1 , wherein the V2X message includes QoS Quality Class Indicator (QCI) information. 
     
     
         5 . The method of  claim 1 , further comprising:
 transmitting, the V2X message to a particular geographic region based on the configuration information.   
     
     
         6 . The method of  claim 2 , wherein the V2X message is sent via a RSU or a second WTRU. 
     
     
         7 . The method of  claim 1 , wherein the V2X message is received via short message service (SMS), system information block (SIB) broadcast, MBMS, wireless application protocol (WIP), or hypertext markup language (HTML) push message. 
     
     
         8 . A first wireless transmit/receive unit (WTRU) comprising:
 one or more receivers operatively coupled to one or more processors configured to receive configuration information related to a vehicle to everything (V2X) communication from a V2X Control Function, the configuration information comprising an associated User Service Description (USD) information;   the one or more receivers operatively coupled to the one or more processors further configured to use the USD to receive a multimedia broadcast multicast service (MBMS) broadcast, wherein the broadcast contains an address of a V2X Application Server; and   one or more transmitters operatively coupled to the one or more processors configured to transmit a V2X message to the V2X Application Server using the address received via MBMS.   
     
     
         9 . The WTRU of  claim 8 , wherein the configuration information further comprises one or more of: an access point name (APN) of a local network for V2X communication, a local gateway (LGW) address, a local home network (LHN) identity, relay node information, a road side unit (RSU) address, a temporary mobile group identity (TMGI), priority information or quality of service (QoS) parameters. 
     
     
         10 . The WTRU of  claim 8 , wherein the V2X message includes ProSe Per-Packet Priority (PPPP) included priority information. 
     
     
         11 . The WTRU of  claim 8 , wherein V2X message includes QoS Quality Class Indicator (QCI) information. 
     
     
         12 . The WTRU of  claim 8 , the one or more transmitters and one or more processors further configured to transmit the V2X message to a particular geographic region. 
     
     
         13 . The WTRU of  claim 9 , wherein the V2X message is sent via a RSU or a second WTRU. 
     
     
         14 . The WTRU of  claim 8 , wherein the V2X message is received via short message service (SMS), system information block (SIB) broadcast, MBMS, wireless application protocol (WIP), or hypertext markup language (HTML) push message.
