Abstract

A method of mapping data for uplink transmission in a communication system maps data to a transport channel for uplink transmission in accordance with a selected transmission mode for uplink transmission. In the method, a transmission parameter may be extracted from a received signaling message, and a transmission mode for uplink transmission selected based on the extracted transmission parameter. The data, which may be high data rate uplink data, may me mapped from logical channels in a MAC layer to transport channels in a physical layer for transmission on the uplink. The transmission on the uplink may be performed from one of an autonomous transmission mode and a scheduled transmission mode, and the transmission parameter may be at least one of a priority indication parameter related to class priority of a service class of data to be transmitted on the uplink, and a radio channel condition.

Claims

1. A method of mapping data for uplink transmission in a communication system, comprising:

mapping data to a transport channel for uplink transmission in accordance with a selected transmission mode for uplink transmission.

2. The method of claim 1, further comprising:

selecting one of a plurality of selectable transmission modes for uplink transmission based on a given transmission parameter.

3. The method of claim 1, wherein said mapping further includes mapping high date rate data on logical channels in a MAC layer to transport channels in a physical layer for transmission on the uplink.

4. The method of claim 2, further comprising:

extracting said transmission parameter from one of an uplink signaling message and a downlink signaling message.

5. The method of claim 4, wherein said extracting further includes extracting one of a priority indication parameter and a radio channel condition from the uplink or downlink signaling message.

6. The method of claim 4, wherein said uplink signaling message includes information informing a Node B of the priority of data available for uplink transmission at a user equipment.

7. The method of claim 4, wherein said downlink signaling message includes information informing a user equipment of a transmission opportunity.

8. The method of claim 2, wherein said given transmission parameter is one of a priority indication parameter and a radio channel condition.

9. The method of claim 8, wherein said priority indication parameter relates to class priority of a service class of data to be transmitted on the uplink.

10. The method of claim 2, wherein said selecting includes selecting at least one of an autonomous transmission mode and a scheduled transmission mode to transmit high data rate data on the uplink.

11. The method of claim 2, wherein said selecting further includes managing hybrid Automatic Repeat request (HARQ) transmission and reception and flow of high data rate data according to the class priority of the high data rate data.

12. The method of claim 11, wherein said managing of HARQ transmission and reception and flow of data is performed at a Node B and at a user equipment.

13. The method of claim 12, wherein the mapped data is transmitted as a new transmission or a retransmission based on a received downlink signaling response message.

14. The method of claim 13, wherein the received downlink signaling response message is one of an acknowledgment (ACK) and a negative acknowledgment (NACK) in response to an uplink signaling message

15. A method of mapping data for uplink transmission in a communication system, comprising:

extracting at least one transmission parameter from a received signaling message;

selecting one of a plurality of selectable transmission modes for uplink transmission based on the extracted transmission parameter; and

mapping data to a transport channel for uplink transmission in accordance with the selected transmission mode.

16. The method of claim 15, wherein said extracting further includes extracting one of a priority indication parameter and a radio channel condition from the signaling message.

17. The method of claim 16, wherein said priority indication parameter relates to class priority of a service class of data to be transmitted on the uplink.

18. The method of claim 15, wherein said selecting includes dynamically selecting at least one of an autonomous transmission mode and a scheduled transmission mode to transmit high data rate data on the uplink.

19. The method of claim 15, wherein said mapping further includes mapping high date rate data on logical channels in a MAC layer to transport channels in a physical layer for transmission on the uplink.
