In a digital communication system in which digital data is transmitted in data frames of a preselected time duration, a method and apparatus for formatting digital data in each data frame. A set of data bits of a first data type having a bit count corresponding to one of a plurality of predetermined bit counts are provided. A set of parity check bits for the set of data bits of said first data type are generated when the bit count is a highest bit count or a next to highest bit count. A set of tail bits is generated in accordance with a predetermined frame termination format. In respective order the set of data bits of the first data type, the parity check bits, and the tail bits are porovided in a data frame if the bit count is of the highest bit count or of the next to highest bit count. Otherwise, the set of data bits of the first data type and the tail bits are provided in respective order in the data frame.
In a cellular communication system which modulates and transmits data flames on forward and reverse channels, a combination for producing data frames, the combination comprising: means for generating data frames in which each data frame includes a set of traffic bits, each set of traffic bits, each
In a cellular communication system which modulates and transmits data flames on forward and reverse channels, a combination for producing data frames, the combination comprising: means for generating data frames in which each data frame includes a set of traffic bits, each set of traffic bits, each set of traffic data bits including data bits of one or more data types; and bit generator means connected to the means for generating data frames, the bit generator means for: generating a mode bit indicating types of data bits for each data frame having a particular frame bit rate; generating parity check bits for traffic for each data frame having a highest bit count or a next-to-highest bit count of data bits of a first data type; generating tail bits in accordance with a predetermined frame termination format; and providing in respective order: said mode bit, said set of traffic data bits, said parity check bits and said tail bits for each frame having the particular frame bit rate and the highest bit count or next-to-highest bit count; and said set of traffic data bits and said tail bits for all other data frames.
