Abstract

A method and apparatus for configuring a bi-directional channel in a wireless communication system is provided. A user equipment (UE) configures the bi-directional channel which is used for either an uplink (UL) channel or a sidelink (SL) channel, and transmits data via at least one of the UL channel or the SL channel. The bi-direction channel may be used for vehicle-to-everything (V2X) communication.

Claims

1. A method for transmitting data in a wireless communication system, the method performed by a user equipment (UE) and comprising:

detecting that the data is available for a bi-directional transmission that includes an uplink (UL) transmission and a sidelink (SL) transmission;

configuring a bi-directional channel for the bi-directional transmission, the bi-directional channel including an UL channel for the UL transmission and an SL channel for the SL transmission;

selecting the UL channel or the SL channel; and

transmitting the data via the selected UL channel or SL channel,

wherein the UL channel is separated from the SL channel at a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer or a media access control (MAC) layer of the UE, and

wherein there is a single PDCP layer and a single RLC layer for both the UL transmission and the SL transmission.

2. The method of claim 1, wherein the UE is a vehicle.

3. The method of claim 1, wherein the data is related to vehicular communication between vehicles or between a vehicle and another type of device.

4. The method of claim 3, wherein the another type of device is an evolved NodeB (eNB), a new entity for the vehicular communication, a new gateway for the vehicular communication, or a road side unit.

5. The method of claim 1, wherein the data is transmitted via the selected UL channel based on a UL grant.

6. The method of claim 1, wherein the data is transmitted via the selected SL channel based on an SL grant.

7. The method of claim 1, wherein the data is transmitted with a digital signature or encryption.

8. A user equipment (UE) for transmitting data in a wireless communication system, the UE comprising:

a memory configured to store information;

a transceiver configured to transmit and receive information; and

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

detect that data is available for a bi-directional transmission that includes an uplink (UL) transmission and a sidelink (SL) transmission;

configure a bi-directional channel for the bi-directional transmission, the bi-directional channel including an UL channel for the UL transmission and an SL channel for the SL transmission;

select the UL channel or the SL channel; and

control the transceiver to transmit the data via the selected UL channel or SL channel,

wherein the UL channel is separated from the SL channel at a packet data convergence protocol (PDCP) layer, a radio link control (RLC) layer or a media access control (MAC) layer of the UE, and

wherein there is a single PDCP layer and a single RLC layer for both the UL transmission and the SL transmission.

9. The UE of claim 8, wherein the UE is a vehicle.

10. The UE of claim 8, wherein the data is related to vehicular communication between vehicles or between a vehicle and another type of device.

11. The UE of claim 10, wherein the another type of device is an evolved NodeB (eNB), a new entity for the vehicular communication, a new gateway for the vehicular communication, or a road side unit.

12. The UE of claim 8, wherein the data is transmitted via the selected UL channel based on a UL grant.

13. The UE of claim 8, wherein the data is transmitted via the selected SL channel based on an SL grant.

14. The UE of claim 8, wherein the data is transmitted with a digital signature or encryption.
