Claim 7

An apparatus for rescheduling scheduled transmissions between a base station and a target remote station, comprising: means for scheduling preamble information and data traffic for transmission to the target remote station, wherein the scheduling means packs preamble information and data traffic into a plurality of preamble subpackets and a plurality of data traffic subpackets that are to be transmitted to the target remote station, and the scheduling means is responsive to signals received on an acknowledgment channel, wherein if no signal is received on the acknowledgment channel within a reasonable time period, then the scheduling means reschedules the transmission of preamble information and data traffic to the remote station, but if the signal received on the acknowledgment channel is an acknowledgment from the target remote station, then the scheduling means schedules a transmission of new preamble information and new data traffic; and if the signal received on the acknowledgment channel is a negative acknowledgment from the target remote station, then the scheduling means continues with the scheduling by transmitting an additional one of the plurality of preamble subpackets and an additional one of the plurality of data traffic subpackets; and if the signal received on the acknowledgment channel is an acknowledgment from a false remote station, then the scheduling means ignores the signal and continues with the scheduling by transmitting an additional one of the plurality of preamble subpackets and an additional one of the plurality of data traffic subpackets; and if the signal received on the acknowledgment channel is a negative acknowledgment from a false remote station, then the scheduling means ignores the signal and suspends all transmissions for a predetermined amount of time; and means for transmitting at least one of the plurality of preamble subpackets and at least one of the plurality of data traffic subpackets in accordance with the scheduling.

Claim 8

An apparatus for rescheduling scheduled transmissions between a base station and a target remote station, comprising: means for scheduling preamble information and data traffic for transmission to the target remote station, wherein the scheduling means packs preamble information and data traffic into a plurality of preamble subpackets and a plurality of data traffic subpackets that are to be transmitted to the target remote station, and the scheduling means is responsive to signals received on an acknowledgment channel, wherein if no signal is received on the acknowledgment channel within a reasonable time period, then the scheduling means reschedules the transmission of preamble information and data traffic to the remote station, but if the signal received on the acknowledgment channel is an acknowledgment from the target remote station, then the scheduling means schedules a transmission of new preamble information and new data traffic; and if the signal received on the acknowledgment channel is a negative acknowledgment from the target remote station, then the scheduling means continues with the scheduling by transmitting an additional one of the plurality of preamble subpackets and an additional one of the plurality of data traffic subpackets; and if the signal received on the acknowledgment channel is an acknowledgment from a false remote station, then the scheduling means ignores the signal and continues with the scheduling by transmitting an additional one of the plurality of preamble subpackets and an additional one of the plurality of data traffic subpackets; and if the signal received on the acknowledgment channel is a negative acknowledgment from a false remote station, then the scheduling means ignores the signal and suspends all transmissions for a predetermined amount of time; and means for transmitting at least one of the plurality of preamble subpackets and at least one of the plurality of data traffic subpackets in accordance with the scheduling.
