Abstract

An apparatus and method for communication including determining an assignment for one of a plurality of symbol durations in a format combination; determining if at least one bit from one or more first upper channels is available if the assignment is associated with the one or more first upper channels and occupying the one of the plurality of symbol durations with the at least one bit, or if unavailable, occupying the one of the plurality of symbol durations with at least one bit from one or more second upper channels or another first upper channel, wherein the first upper channels and the second upper channels are different; and disabling transmission of format information; or including enabling a BTFD hypothesis testing mode; receiving one or more symbol durations on a physical channel; and attempting to decode the received symbol duration with a first hypothesis that a DCCH channel is not transmitted.

First claim

What is claimed is:

1 . A method for communication over a downlink channel comprising:
enabling a blind transport format detection (BTFD) hypothesis testing mode; receiving one of a plurality of symbol durations on a physical channel; and attempting to decode the one of the plurality of symbol durations with a first hypothesis that a DCCH channel is not transmitted.

2 . The method of claim 1 , wherein if the attempting is not successful, further comprising decoding the one of the plurality of symbol durations with a second hypothesis that the DCCH channel is transmitted.

3 . The method of claim 1 , further comprising detecting joint error detection encoding bits from the DCCH channel or a DTCH channel.

4 . The method of claim 1 , wherein the format of the physical channel is a pilot-free slot format, and wherein the physical channel comprises a plurality of separate orthogonal variable spreading factor (OVSF) codes for a plurality of user equipment (UE).

5 . An apparatus for communication over a downlink channel comprising:
a memory for storing at least one blind transport format detection (BTFD) hypothesis algorithm; and at least one processor coupled to the memory, the at least one processor configured to perform the following: enable a blind transport format detection (BTFD) hypothesis testing mode; receive one of a plurality of symbol durations on a physical channel; and attempt to decode the one of the plurality of symbol durations with a first hypothesis that a DCCH channel is not transmitted.

6 . The apparatus of claim 5 , wherein if the attempting is not successful, the at least one processor is further configured to decode the one of the plurality of symbol durations with a second hypothesis that the DCCH channel is transmitted.

7 . The apparatus of claim 5 , wherein the at least one processor is further configured to detect joint error detection encoding bits from the DCCH channel or a DTCH channel.

8 . The apparatus of claim 5 , wherein the format of the physical channel is a pilot-free slot format, and wherein the physical channel comprises a plurality of separate orthogonal variable spreading factor (OVSF) codes for a plurality of user equipment (UE).

9 . An apparatus for communication over a downlink channel comprising:
a memory for storing at least one blind transport format detection (BTFD) hypothesis algorithm; means for enabling a blind transport format detection (BTFD) hypothesis testing mode; means for receiving one of a plurality of symbol durations on a physical channel; and means for attempting to decode the one of the plurality of symbol durations with a first hypothesis that a DCCH channel is not transmitted, wherein if attempting to decode with the first hypothesis is not successful, the means for attempting decodes the one of the plurality of symbol durations with a second hypothesis that the DCCH channel is transmitted.

10 . A computer-readable medium storing computer executable code, operable on a device comprising a memory for storing at least one blind transport format detection (BTFD) hypothesis algorithm and a processor coupled to the memory, the computer executable code comprising:
instructions for causing the processor to enable a blind transport format detection (BTFD) hypothesis testing mode; instructions for causing the processor to receive one of a plurality of symbol durations on a physical channel; and instructions for causing the processor to attempt to decode the one of the plurality of symbol durations with a first hypothesis that a DCCH channel is not transmitted, and wherein if the attempt to decode with the first hypothesis is not successful, the instructions causes the processor to attempt to decode the one of the plurality of symbol durations with a second hypothesis that the DCCH channel is transmitted.
