Abstract

A method and apparatus for transmitting a paging for vehicle-to-everything (V2X) communication in a wireless communication system is provided. A network node receives data corresponding to the V2X communication from a first UE, and transmits the paging indicating the V2X communication to a second UE. The network node may further broadcast the data to one or more UEs.

Claims

1. A method for transmitting, by a network node, a paging for vehicle-to-everything (V2X) communication in a wireless communication system, the method comprising:

receiving data for the V2X communication from a first group of user equipments (UEs) via a specific channel by using a connectionless transmission,

wherein the connectionless transmission is a specific type of transmission which the data is routed to a V2X gateway;

re-constructing the data by checking whether the data is duplicated or not; and

transmitting the paging including the V2X communication to a second group of UEs,

wherein the paging includes the re-constructed data.

2. The method of claim 1, wherein the transmitting the paging comprises:

determining whether to relay the data to the second group UEs via the page.

3. The method of claim 1, further comprising transmitting a specific radio network temporary identity (RNTI), which schedules the transmission of the paging including the V2X communication, via a physical downlink control channel (PDCCH).

4. The method of claim 1, wherein the network node is one of an evolved NodeB (eNB), a entity for the V2X communication, a gateway for the V2X communication, or a road side unit (RSU).

5. The method of claim 1, wherein one or more of the first group of UEs or the second group of UEs is a vehicle.

6. The method of claim 1, wherein the V2X communication is a vehicular communication between vehicles or between a vehicle and other type of device.

7. A network node comprising:

a memory;

a transceiver; and

a processor coupled to the memory and the transceiver, and configured to;

control the transceiver to receive data for the V2X communication from a first group of user equipments (UE) via a specific channel by using a connectionless transmission,

wherein the connectionless transmission is a specific type of transmission which the data is routed to a V2X gateway;

control the transceiver to re-construct the data by checking whether the data is duplicated or not; and

control the transceiver to transmit a paging including the V2X communication to a second group of UEs,

wherein the paging includes the re-constructed data.
