Abstract

A method and system for wireless communication of different information types over a wireless channel, is provided. Information comprising different information types is formed into a composite aggregation of the different information types, and the composite aggregation is transmitted from a sender to a receiver over a wireless channel. A composite acknowledgement (ACK) format is utilized by the receiver to reduce the overhead in low-rate channels.
