US Patent 7539214 Variable reliability wireless communication transmission method and apparatus

A mobile station (150) senses (300) at least one boundary of a wireless communication packet (200) which includes a plurality of frames. The mobile station (150) then determines (310) at least a first group (210) and a second group (230) of frames at least in part in relation to the sensed boundary. The first group (210) of frames is received (320) at a first target reliability, and the second group (230) of frames is received (330) at a second target reliability. Optionally, the frames are sent (400) or received at a variable reliability in relation to the frames' distances from one or more boundaries (240, 250) of the packet (200).
