Abstract

A method and apparatus determine whether reserved bits of a field are assigned a function; if not, the bits may be used for enhanced functions such as equalization and synchronization. An indication whether reserved bits have been assigned a function may be sent on a broadcast channel by a usage-information element. Decoding of the coded superframe phase/packet channel feedback (CSFP/PCF) field also is improved by reducing the number of possible codewords in the CSFP/PCF field, based on the superframe phase (SFP) information. The length of a codeword to be decoded may be reduced based on an indication in the usage-information element whether a CSFP/PCF field bit is reserved. Generally, the block code of any channel coded word, not necessarily packet data, may be effectively reduced based on knowledge of some information in the coded word.
