Abstract
Rather than attaching a preamble to a data traffic subpacket, a preamble channel is transmitted along with a traffic channel. An ARQ channel is established on the reverse link in response to a received transmission on the preamble channel and the traffic channel. In accordance with the type of ARQ signal received or the lack of receipt thereof, a scheduling element in the base station alters an already existing transmission schedule for transmitting old data traffic or new data traffic.
