Method and apparatus for transmitting paging for V2X communication in wireless communication system
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.
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.
