CLAIMS

What is claimed is:

1. A method of receiving resources at a user equipment (UE), comprising:

receiving information comprising a medium occupation and a resource block group (RBG) size from a gNB, wherein the resource block group size is based on medium occupancy.

2. The method according to claim 1, further comprising receiving an additional guard band around each side of the occupied medium.

3. The method according to claim 1 , wherein the information comprising the medium occupation and the resource block group (RBG) size is from a radio resource control (RRC) layer or is predefined.

4. The method according to claim 1, wherein the medium occupation is received by the UE using information carried by a common signal on an L1 channel, and wherein there is an implicit mapping between the RBG size and the medium occupancy.

5. The method according to claim 1, wherein the medium occupation is received by the UE using information indicated by a bitmap and received by the UE on a UE specific channel, and wherein at least one bit in the bitmap represents one or more RBGs and wherein there is an implicit mapping between the RBG size and the configured BWP.

6. The method according to claim 1 , further comprising:

reducing resource allocation (RA) overhead by

receiving a starting PRB, RBG, or interlace;

spanning a number of said RBs, RBGs, or interlaces across multiple channels including unoccupied channels and guard bands; and

automatically skipping PRBs, RBGs, or interlaces in the guard band and in unoccupied channels.

7. The method according to claim 1, further comprising:

reducing resource allocation (RA) overhead by joint coding a resource allocation (RA) indication and a medium occupation index comprising:

receiving a starting PRB in a first allocated channel and an end PRB in a last allocated channel; and

receiving medium occupancy indicating the first and the last allocated channel.

8. The method according to claim 1, further comprising:

receiving access to at least one interlace of equally spaced PRBs across one channel of the UE.

9. The method according to claim 1, further comprising:

receiving access to at least one interlace or one partial interlace of equally spaced PRBs across a plurality of channels within a system bandwidth.

10. The method according to claim 2, wherein the guard band is assigned around said occupied medium to avoid adjacent channel leakage-power if the medium is not fully occupied.

11. The method according to claim 4, wherein the message carried on the L1 channel is transmitted in the first slot of a TXOP and repeated in subsequent slots of the TXOP.

12. An apparatus for receiving resources at a user equipment (UE), comprising:

means for receiving information comprising a medium occupation and a resource block group (RBG) size from a gNB, wherein the resource block group size is based on a medium occupancy.

13. The apparatus according to claim 12, further comprising means for receiving an additional guard band around occupied medium.

14. The apparatus according to claim 12, wherein the information comprising the medium occupation and the resource block group (RBG) size is from a radio resource control (RRC) layer or is predefined.

15. The apparatus according to claim 12, wherein the medium occupation is received by the UE using information carried by a common signal on an L1 channel, and wherein there is an implicit mapping between the RBG size and the medium occupancy.

16. The apparatus according to claim 12, wherein the medium occupation is received by the UE using information indicated by a bitmap and received by the UE on a UE specific channel, wherein at least one bit in the bitmap represents one or more RBGs and wherein there is an implicit mapping between the RBG size and the configured BWP.

17. The apparatus according to claim 12, further comprising:

means for reducing resource allocation (RA) overhead, comprising:

means for receiving a starting PRB, RBG, or interlace;

means for spanning a number of said RBs, RBGs, or interlaces across multiple channels including unoccupied channels and guard bands; and

means for automatically skipping FRBs, RBGs, or interlaces in the guard band and in unoccupied channels.

18. The apparatus according to claim 12, further comprising:

reducing resource allocation (RA) overhead by joint coding a resource allocation (RA) indication and a medium occupation index comprising:

receiving a starting PRB in a first allocated channel and an end PRB in a last allocated channel; and

receiving medium occupancy indicating the first and the last allocated channel.

19. The apparatus according to claim 12, further comprising:

receiving access to at least one interlace of equally spaced PRBs across one channel of the UE.

20. The apparatus according to claim 12, further comprising:

receiving access to an interlace or one partial interlace of equally spaced PRBs across a plurality of channels within a system bandwidth.

21. The apparatus according to claim 13, wherein the guard band is assigned around said occupied medium to avoid adjacent channel leakage-power if the medium is not fully occupied.

22. The apparatus according to claim IS, wherein the information carried on the L1 channel is transmitted in the first slot of a TXOP and repeated in subsequent slots of the TXOP.

23. An apparatus to receive resources at a user equipment (UE), comprising:

a memory; and

a processor coupled to the memory, configured to:

receive information comprising a medium occupation and a resource block group (RBG) size from a gNB, wherein the resource block group size is based on a medium occupancy.

24. The apparatus according to claim 23, wherein the processor is further configured to receive an additional guard band around each side of the occupied medium.

25. The apparatus according to claim 23, wherein the information comprising the medium occupation and the resource block group (RBG) size is from a radio resource control (RRC) layer or is predefined.

26. The apparatus according to claim 23, wherein the medium occupation is received by the UE using information carried by a common signal on an L1 channel, and wherein there is an implicit mapping between the RBG size and the medium occupancy.

27. The apparatus according to claim 23, wherein the medium occupation is received by the UE using information indicated by a bitmap and received by the UE on a UE specific channel, wherein at least one bit in the bitmap represents one or more RBGs and wherein there is an implicit mapping between the RBG size and the configured BWP.

28. The apparatus according to claim 23, wherein the processor is further configured to:

reduce resource allocation (RA) overhead by

receive a starting PRB, RBG, or interlace;

span a number of said RBs, RBGs, or interlaces across multiple channels including unoccupied channels and guard bands; and

automatically skip PRBs, RBGs, or interlaces in the guard band and in unoccupied channels.

29. The apparatus according to claim 23, wherein the processor is further configured to:

reducing resource allocation (RA) overhead by joint coding a resource allocation (RA) indication and a medium occupation index comprising:

receiving a starting PRB in a first allocated channel and an end PRB in a last allocated channel; and

receiving medium occupancy indicating the first and the last allocated channel.

30. A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processor of an apparatus to receive resources at a user equipment (UE), comprising:

receive information comprising a medium occupation and a resource block group (RBG) size from a gNB, wherein the resource block group size is based on a medium occupancy.
