Abstract

A transport channel multiplexing system provides improved use of wireless resources in a shared data channel system. For example, the transport channel system reduces the amount of transport format information required for using a shared data channel, such as the actual number of packet data units in a transport channel of the shared data channel. Additionally, by scheduling or multiplexing coded sub-blocks from one or more transport channels over the shared data channel, the transport channel multiplexing system can provide improved integration with other important features, such as incremental redundancy, fast adaptation to channel conditions and transport channel dependent quality of service (QOS) control, to provide improved system performance.

Claims

1. A method comprising the steps of:

receiving packet data units in a buffer;

concatenating a plurality of packet data units to produce a transport block set;

coding said transport block set to a coded block;

rate matching said coded block to form coded sub-blocks and coded sub-block being subject to additional processing;

time-multiplexing the rate-matched coded sub-blocks into a coded shared transport channel; and

mapping a plurality of transport format combination indication signaling information into a number of packet data units transmitted to a wireless unit in association with the coded shared transport channel.

2. The method of claim 1 comprising:

interleaving at least said coded sub-block.

3. The method of claim 1, wherein the plurality of transport format combination indication signaling information comprises rate information and transport channel identity.
