A "hybrid" ARQ system within a multiple access wireless communications environment is provided for-recombining ARQ retransmission signals with information obtained from corresponding previously failed transmissions of the same signal which had been sent and received within the air interface. Forward Error Correction (FEC) is implemented within an ARQ environment by using whatever acquired information has been previously obtained from RAKE processed transmitted and retransmitted signals and trying to correct the information by combining the signals and without retransmission.

[ What is claimed is:] [1.] A multiple access system of communication across a wireless interface comprising:a transmitter for transmitting a signal representative of a packet of information and retransmitting the signal representation of the packet of information;a receiver for receiving the signal representations of the packet of information; anda means for processing the signal representations of the packet of information by combining the transmitted signals with the retransmitted signals to obtain an output signal representation of the packet of information;the receiver sending an ARQ signal to the transmitter when the output signal is deemed to be unreliable, when a default power threshold is not exceeded, and the transmitter sending the retransmitted signal in response to the ARQ signal.
