Abstract

A wireless transmit/receive unit (WTRU) may receive configuration information indicating a set of physical channel frequency resources. The WTRU may receive indication information indicating an allocation of at least a subset of the set of physical channel frequency resources. Further, the WTRU may determine a time period, and one or more physical channel frequency resources from the subset of the set of physical channel frequency resources. The WTRU may transmit data in a physical shared channel transmission using the determined one or more physical shared channel frequency resources during the determined time period. Further, the WTRU may determine a time location for reception of hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the transmitted data, and the determination of the time location may be based on the subset of the set of physical channel frequency resources. The WTRU may receive the HARQ-ACK information during the determined time location.

Claims (35)

1. A method for use in a wireless transmit/receive unit (WTRU) for multiple access wireless communications, the method comprising:

receiving configuration information indicating a set of physical channel frequency resources;

receiving indication information indicating an allocation of at least a subset of the set of physical channel frequency resources;

determining one or more physical shared channel frequency resources from the subset of the set of physical channel frequency resources and a time period;

transmitting data in a physical shared channel transmission using the determined one or more physical shared channel frequency resources during the determined time period;

determining a time location for reception of hybrid automatic repeat request acknowledgement (HARQ-ACk) information associated with the transmitted data, wherein the determination of the time location is based on the subset of the set of physical channel frequency resources; and

receiving the HARQ-ACK information during the determined time location.

2. The method of claim 1 , wherein the determination of the one or more physical shared channel frequency resources from the subset of the set of physical channel frequency resources is based on a WTRU-ID.

3. The method of claim 1 , wherein the time period is determined based on a WTRU-ID.

4. The method of claim 1 , wherein the time period is within a fixed time window.

5. The method of claim 1 , wherein the determination of the time location is further based on a physical channel resource index.

6. The method of claim 1 , wherein control information is transmitted on the physical shared channel transmission.

7. The method of claim 1 , wherein the HARQ-ACK information is received in a slot.

8. The method of claim 1 , wherein the configuration information is received via radio resource control (RRC) signaling.

9. The method of claim 1 , wherein the indication information is received via RRC signaling.

10. The method of claim 1 , wherein the indication information includes a presence indication.

11. A wireless transmit/receive unit (WTRU) for multiple access wireless communications, the WTRU comprising:

a transceiver; and

the transceiver operatively coupled to a processor;

wherein:

the transceiver is configured to receive configuration information indicating a set of physical channel frequency resources;

the transceiver is configured to receive indication information indicating an allocation of at least a subset of the set of physical channel frequency resources;

the processor is configured to determine one or more physical shared channel frequency resources from the subset of the set of physical channel frequency resources and a time period;

the transceiver and the processor are configured to transmit data on a physical shared channel transmission using the determined one or more physical channel frequency resources during the determined time period;

the processor is configured to determine a time location for reception of hybrid automatic repeat request acknowledgement (HARQ-ACK) information associated with the transmitted data, wherein the determination of the time location is based on the subset of the set of physical channel frequency resources; and

the transceiver and the processor are configured to receive the HARQ-ACK information during the determined time location.

12. The WTRU of claim 11 , wherein the determination of the one or more physical shared channel frequency resources from the subset of the set of physical channel frequency resources is based on a WTRU-ID.

13. The WTRU of claim 11 , wherein the time period is determined based on a WTRU-ID.

14. The WTRU of claim 11 , wherein the time period is within a fixed time window.

15. The WTRU of claim 11 , wherein the determination of the time location is further based on a physical channel resource index.

16. The WTRU of claim 11 , wherein control information is transmitted on the physical shared channel transmission.

17. The WTRU of claim 11 , wherein the HARQ-ACK information is received in a slot.

18. The WTRU of claim 11 , wherein the configuration information is received via radio resource control (RRC) signaling.

19. The WTRU of claim 11 , wherein the indication information is received via RRC signaling.

20. The WTRU of claim 11 , wherein the indication information includes a presence indication.
