Abstract: The present invention relates to wireless voice and data communication systems. More particularly, the present invention relates to novel and improved methods and apparatus for transmitting data traffic on a communication channel. One such method comprises the steps of packaging a data payload into a plurality of subpackets; transmitting a first subpacket to a remote station; if the channel conditions are optimal, transmitting a remaining portion of the plurality of subpackets to the remote station; and if the channel conditions are not optimal within a predetermined time duration, then transmitting a remaining portion of the plurality of subpackets during unfavorable channel conditions. The apparatus may comprise means for packaging a data payload into a plurality of subpackets; means for transmitting a plurality of subpackets to a remote station; means for deciding, after the means for transmitting a plurality of subpackets has transmitted a first subpacket, whether: if the channel conditions are optimal, to transmit a remaining portion of the plurality of subpackets to the remote station; and if the channel conditions are not optimal within a predetermined time duration, then to transmit a remaining portion of the plurality of subpackets during unfavorable channel conditions.

Abstract: A method for coherent estimation of the traffic-to-pilot energy ratio is presented. A received preamble is decoded (20), and then re-encoded (22). The received preamble is then multiplied by the re-encoded preamble (23). The results are summmed (24), squared (26), and then divided by a pilot energy value (28). In another method, a message (41) carrying energy information can be inserted between a subpacket preamble (40) and a subpacket (42).

Abstract: A power control system for controlling the transmission power in a system wherein the transmission power may be gated or capped. The receiver employs a combination of closed loop and outer loop power control. The outer loop is frozen upon detection by the receiver that the signal has been capped or gated.
