Abstract

Systems, methods, and devices for sidelink transmit-receive distance related determinations are disclosed herein. In one example, a wireless transmit receive unit (WTRU) may be configured with an associate between range information and zone configuration. The WTRU receive an indication of a specific range information requirement and determine its own zone location based on the configured information and location means (e.g., GPS). The WTRU may also receive zone location information of a transmitting device, and determine the distance between the WTRU and the transmitting device.

Claims (25)

1. A method implemented by a first wireless transmit receive unit (WTRU), the method comprising:

receiving configuration information, wherein the configuration information includes a set of zone configurations, wherein each zone configuration of the set of zone configurations is associated with a respective communication range requirement, wherein each zone configuration of the set of zone configurations has a respective zone associated length;

determining a zone associated length from the set of zone configurations based on a communication range requirement of a transport block (TB), wherein the TB is associated with a vehicle-to-everything (V2X) service;

determining a zone ID associated with a transmission of the TB based on the zone associated length and based on location information of the first WTRU; and

transmitting the determined zone ID associated with the transmission of the TB.

2. The method of claim 1 , wherein the determined zone ID is included in control information which is transmitted in a physical sidelink (SL) control channel.

3. The method of claim 1 , wherein the transmission of the TB is a groupcast transmission.

4. The method of claim 1 , wherein the transmission of the TB is a data transmission transmitted on a shared channel.

5. The method of claim 2 , wherein the control information is SL control information (SCI) on a physical sidelink control channel.

6. The method of claim 1 , wherein the determined zone ID is transmitted to a second WTRU.

7. The method of claim 6 , wherein the transmission of the TB is for the second WTRU.

8. The method of claim 2 , wherein the control information includes a first stage SL control information and a second stage SL control information.

9. A first wireless transmit/receive unit (WTRU) comprising:

a processor, and

a transceiver coupled to the processor,

the processor and transceiver configured to receive configuration information, wherein the configuration information includes a set of zone configurations, wherein each zone configuration of the set of zone configurations is associated with a respective communication range requirement, wherein each zone configuration of the set of zone configurations has a respective zone associated length;

the processor and transceiver configured to determine a zone associated length from the set of zone configurations based on a communication range requirement of a transport block (TB), wherein the TB is associated with a vehicle-to-everything (V2X) service;

the processor and transceiver configured to determine a zone ID associated with a transmission of the TB based on the zone associated length and based on location information of the first WTRU; and

the processor and transceiver configured to transmit the determined zone ID associated with the transmission of the TB.

10. The first WTRU of claim 9 , wherein the determined zone ID is included in control information which is transmitted in a physical sidelink (SL) control channel.

11. The first WTRU of claim 9 , wherein the transmission of the TB is a groupcast transmission.

12. The first WTRU of claim 9 , wherein the transmission of the TB is a data transmission transmitted on a shared channel.

13. The first WTRU of claim 10 , wherein the control information is SL control information (SCI) on a physical sidelink channel.

14. The first WTRU of claim 9 , wherein the determined zone ID is transmitted to a second WTRU.

15. The first WTRU of claim 14 , wherein the transmission of the TB is for the second WTRU.
