Abstract

A method for providing vehicular communication in an advanced wireless communication system, which includes instant feedback to enable synchronized cooperative driving, is provided. The method comprises: identifying, at a first V2X-UE, one or more second V2X-UEs in proximity to the first V2X-UE; transmitting, from the first V2X-UE- and to the one or more second V2X-UEs, control channel information identifying a portion of a data pool allocated for V2X intention data; transmitting, from the first V2X-UE and to the one or more second V2X-UEs and on the identified portion of the data pool, V2X intention data; and receiving, at a first V2X-UE- and on a reserved feedback channel, confirmation of receipt of the V2X intention data from a V2X-UE of the one or more second V2X-UEs.

Claims

1. A method for providing vehicular communication in an advanced wireless communication system, the method comprising:

identifying, at a first V2X-UE, one or more second V2X-UEs in proximity to the first V2X-UE;

transmitting, from the first V2X-UE and to the one or more second V2X-UEs, control channel information identifying a portion of a data pool allocated for V2X intention data;

transmitting, from the first V2X-UE and to the one or more second V2X-UEs and on the identified portion of the data pool, V2X intention data; and

receiving, at the first V2X-UE and on a reserved feedback channel, confirmation of receipt of the V2X intention data from a V2X-UE of the one or more second V2X-UEs.

2. The method of claim 1, wherein the control channel information is transmitted in a control channel pool of a resource pool, and the data pool is a data pool of the resource pool.

3. The method of claim 2, wherein the resource pool is repeated periodically in time.

4. The method of claim 2, wherein the resource pool comprises a sub-pool of a logical resource pool.

5. The method of claim 4, wherein the logical resource pool is repeated periodically in time.

6. The method of claim 4, wherein the logical resource pool comprises a plurality of resource sub-pools, and wherein the resource sub-pool is frequency multiplexed with other resource sub-pools.

7. The method of claim 6, wherein the resource sub-pool is identified by:

a periodicity of the sub-pool, a resource pool in which the sub-pool starts, a resource block within the resource pool on which the sub-pool starts, and a resource block on which the sub-pool ends.

8. The method of claim 6, wherein the resource sub-pool has a waveform or waveform numerology different to another resource sub-pool within the logical resource pool.

9. The method of claim 2, wherein the control channel pool and corresponding data pool of the resource pool are frequency-multiplexed.

10. The method of claim 2, where the control channel pool is configured to use a first waveform numerology designed for a small and fixed payload size.

11. The method of claim 2, wherein the control channel pool comprises a plurality of time-frequency multiplexed control channels.

12. The method of claim 11, wherein the plurality of time-frequency multiplexed control channels have configurable size.

13. The method of claim 12, wherein the plurality of time-frequency multiplexed control channels span over one transmission-time-base unit and across one or more resource blocks in frequency.

14. The method of claim 2, wherein the data pool is configured to use a second waveform numerology designed for a large and variable payload size.

15. The method of claim 1, wherein the reserved feedback channel comprises one or more resource blocks that are implicitly defined in the data pool by a configurable repeating structure.

16. The method of claim 15, wherein the one or more resource blocks comprises a first resource block set and a second resource block set.

17. The method of claim 16, wherein a V2X-UE of the one or more second V2X-UEs is implicitly configured to use the first reserved resource block set for providing confirmation of receipt of the V2X intention data, when the V2X intention data was received on resource blocks prior to the first resource block of the first reserved resource block set.

18. The method of claim 16, wherein a V2X-UE of the one or more second V2X-UEs is implicitly configured to use the second reserved resource block set for providing confirmation of receipt of the V2X intention data, when the V2X intention data was received on resource blocks subsequent to the first resource block of the first reserved resource block set and prior to the first resource block of the second reserved resource block set.

19. The method of claim 1, wherein the reserved feedback channel comprises one or more resource blocks that are explicitly defined.

20-33. -33. (canceled)

34. An advanced wireless communication system, the system comprising:

a plurality of V2X-UEs including a first V2X-UE configured to;

identify one or more second V2X-UEs in proximity to the first V2X-UE;

transmit, to the one or more second V2X-UEs, control channel information identifying a portion of a data pool allocated for V2X intention data;

transmit, to the one or more second V2X-UEs and on the identified portion of the data pool, V2X intention data; and

receive, on a reserved feedback channel, confirmation of receipt of the V2X intention data from a V2X-UE of the one or more second V2X-UEs.
