INCREASING CAPACITY IN WIRELESS COMMUNICATIONS
First Claim
1. A method of wireless communication, comprising:
- during a first allotted transmission time interval (TTI) comprising a plurality of slots, receiving a composite channel comprising a plurality of transport channels;
determining whether to attempt to decode a first transport channel of the plurality of transport channels before receiving all slots of the plurality of slots of the first allotted TTI; and
attempting to decode said first transport channel in response to said determining whether to attempt to decode,wherein the determining whether to attempt to decode is by reference to an integer N, whereby an attempt is made based on an interval of N slots within a TTI.

Abstract
Techniques to increase the capacity of a W-CDMA wireless communications system. In an exemplary embodiment, early termination of one or more transport channels on a W-CDMA wireless communications link is provided. In particular, early decoding is performed on slots as they are received over the air, and techniques are described for signaling acknowledgment messages (ACK'"'"'s) for one or more transport channels correctly decoded to terminate the transmission of those transport channels. The techniques may be applied to the transmission of voice signals using the adaptive multi-rate (AMR) codec. Further exemplary embodiments describe aspects to reduce the transmission power and rate of power control commands sent over the air, as well as aspects for applying tail-biting convolutional codes in the system.
