1. A medium access control layer (MAC) having termination points at a base station and at user, comprising:
- means for scheduling tasks at the base station; and
means for multiplexing upper layer data into separate first and second channels at the user;
the first channel configured for use when the user is in a scheduled transmission mode, and the second channel configured for use when the user is in an autonomous transmission mode.

Abstract
In a wireless communication system, there is a method of transmitting over a reverse link, where a medium access control layer multiplexes data from upper level layers onto transport channels that are used based on whether the user is in a scheduled transmission mode or an autonomous transmission mode. The transport channels may be mapped to one or more physical channels associated with a particular transport channel, based on whether the transport channel is dedicated for use in the scheduled or autonomous mode.

5. A method of mapping transport channels in a MAC layer onto physical channels of a physical layer at a user, comprising:
-
inputting a first transport channel dedicated for use when the user is in a scheduled transmission mode;
mapping said first transport channel to a first group of physical channels;
inputting a second transport channel dedicated for use when the user is in an autonomous transmission mode;
mapping said second transport channel to a second group of physical channels that are not associated with said first transport channel. - View Dependent Claims (6, 7)

8. A method of transmitting information from a user, comprising:
-
multiplexing upper layer data onto a first transport channel configured for use in a scheduled transmission mode and onto a second transport channel configured for use in an autonomous transmission mode;
mapping the first and second transport channels to groups of physical channels for encoding, so that a first group of physical channels is designated for carrying bits of data from said first transport channel, and a second group of physical channels is designated for carrying bits of data from said second transport channel; and
transmitting the first and second groups of physical channels.

- 9. A method of multiplexing data in a medium access control (MAC) layer of a user, the MAC layer mapping data from upper level layers to a first transport channel defined for a scheduled transmission mode of operation and to a second transport channel defined for an autonomous transmission mode of operation, the user'"'"'s MAC layer multiplexing upper level data into one or more of the first and second transport channels based on a trigger.
- 11. A transport channel of a medium access control (MAC) layer, the transport channel receiving multiplexed data from the MAC layer that is substantially delay tolerant and error tolerant, the transport channel used by the MAC layer when a user has received a scheduling grant and is in a scheduled mode of operation, the transport channel characterized by a transmission time interval less than about 10 ms, and subject to one or more of fast scheduling, adaptive data rate selection and Hybrid Automatic Repeat Request (H-ARQ) processes from a controlling entity.
- 13. A transport channel of a medium access control (MAC) layer, the transport channel receiving multiplexed data from the MAC layer that is substantially delay intolerant, the transport channel used by the MAC layer when a user is operating in an autonomous transmission mode, the transport channel characterized by a transmission time interval of at least 10 ms and multiples thereof, and subject to one or more of fast scheduling, adaptive data rate selection and Hybrid Automatic Repeat Request (H-ARQ) processes from a controlling entity.

15. A method of signaling a base station from a user, comprising:
transmitting a signaling message over a physical channel to the base station. - View Dependent Claims (16)

17. A method of signaling a base station from a user, comprising:
transmitting a signaling message from the user in a medium access control (MAC) layer to a radio network controller (RNC), the RNC transmitting soft handoff status of the user to one or more base stations involved in the soft handoff.
