The present invention provides a method for reducing transmitted energy
based on early decoding. The method includes accessing a first portion of
a block including a plurality of symbols indicative of an encoded
message. The first portion has been transmitted at a first transmission
power and having less than all of the plurality of symbols. The method
also includes attempting to decode the encoded message using the first
portion of the block, determining whether the encoded message was
decoded, and providing an indication of a second transmission power in
response to determining that the encoded message was decoded.
