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:
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;
if available, occupying the one of the plurality of symbol durations with the at least one bit from the one or more first upper channels, and if not available, 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 one or more first upper channels and the one or more second upper channels are different set of upper channels; and
disabling transmission of format information associated with the format combination.

2. The method of claim 1 , wherein the one or more first upper channels comprises a Dedicated Control Channel (DCCH) channel and the one or more second upper channels comprises one or more Dedicated Traffic Channel (DTCH) channels.

3. The method of claim 2 , wherein the one or more the DTCH channels carries different classes of voice bits.

4. The method of claim 2 , further comprising disabling transmission of a DCCH indicator for the DCCH channel.

5. The method of claim 2 , wherein a single DTCH channel carries a set of classes of voice bits, one or more joint error detection encoding bit and one or more joint error correcting encoding bit.

6. The method of claim 1 wherein a rate-matching (RM) attribute for one of the one or more first upper channel is treated as a zero value if no bit is available from the one of the one or more first upper channel.

7. The method of claim 1 , further comprising transmitting the one of the plurality of symbol durations on a physical channel.

8. The method of claim 7 , 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. The method of claim 7 , wherein one of the one or more first upper channels is a Dedicated Control Channel (DCCH), one of the one or more second upper channels is a Dedicated Traffic Channel (DTCH), the physical channel is a Dedicated Physical Data Channel (DPDCH), and further comprising boosting transmit power of the physical channel when at least one DCCH bit occupies at least one assigned DCCH symbol duration in the format combination.

10. An apparatus for communication over a downlink channel comprising:
a memory for storing at least one bit from one or more first upper channels or at least one bit from one or more second upper channels; and
at least one processor coupled to the memory, the at least one processor configured to perform the following:
determine an assignment for one of a plurality of symbol durations in a format combination;
determine if at least one bit from the one or more first upper channels is available if the assignment is associated with the one or more first upper channels;
if available, occupy the one of the plurality of symbol duration with the at least one bit from the one or more first upper channels and if not available, occupy the one of the plurality of symbol durations with at least one bit from the one or more second upper channels or another first upper channel,
wherein the one or more first upper channels and the one or more second upper channels are different sets of upper channels, and
disable transmission of format information associated with the format combination.

11. The apparatus of claim 10 , wherein the one or more first upper channels comprises a Dedicated Control Channel (DCCH) channel and the one or more second upper channels comprises one or more Dedicated Traffic Channel (DTCH) channels.

12. The apparatus of claim 11 , wherein the one or more the DTCH channels carries different classes of voice bits.

13. The apparatus of claim 11 , wherein the at least one processor is further configured to disable transmission of a DCCH indicator for the DCCH channel.

14. The apparatus of claim 11 , wherein a single DTCH channel carries a set of classes of voice bits, one or more joint error detection encoding bit and one or more joint error correcting encoding bit.

15. The apparatus of claim 10 wherein a rate-matching (RM) attribute for one of the one or more first upper channel is treated as a zero value if no bit is available from the one of the one or more first upper channel.

16. The apparatus of claim 10 , wherein the at least one processor is further configured to transmit the one of the plurality of symbol durations on a physical channel.

17. The apparatus of claim 16 , 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).

18. The apparatus of claim 16 , wherein one of the one or more first upper channels is a Dedicated Control Channel (DCCH), one of the one or more second upper channels is a Dedicated Traffic Channel (DTCH), the physical channel is a Dedicated Physical Data Channel (DPDCH), and wherein the at least one processor is further configured to boost transmit power of the physical channel when at least one DCCH bit occupies at least one assigned DCCH symbol duration in the format combination.

19. An apparatus for communication over a downlink channel comprising:
a memory for storing at least one bit from one or more first upper channels or at least one bit from one or more second upper channels;
means for determining an assignment for one of a plurality of symbol durations in a format combination;
means for determining if at least one bit from the one or more first upper channels is available if the assignment is associated with the one or more first upper channels;
means for occupying the one of the plurality of symbol durations with the at least one bit from the one or more first upper channels if available; and
means for occupying the one of the plurality of symbol durations with at least one bit from the one or more second upper channels or another first upper channel if not available, wherein the one or more first upper channels and the one or more second upper channels are different sets of upper channels; and
means for disabling transmission of format information associated with the format combination.

20. A non-transitory computer-readable medium storing computer executable code, operable on a device comprising a memory for storing at least one bit from one or more first upper channels or at least one bit from one or more second upper channels, and a processor coupled to the memory, the computer executable code comprising:
instructions for causing the processor to determine an assignment for one of a plurality of symbol durations in a format combination;
instructions for causing the processor to determine if at least one bit from the one or more first upper channels is available if the assignment is associated with the one or more first upper channels;
instructions for causing the processor to occupy the one of the plurality of symbol durations with the at least one bit from the one or more first upper channels if available;
instructions for causing the processor to occupy the one of the plurality of symbol durations with at least one bit from the one or more second upper channels or another first u
