US 8,009,658 B2 · Method for sharing bandwidth using reduced duty cycle signals and media access control

Abstract

A method is provided for transmitting data. A first device generates a first signal having a first duty cycle, comprising a first gated-on portion and a first gated-off portion in a time slot; and a second device generates a second signal having second duty cycle, comprising a second gated-on portion and a second gated-off portion in the same time slot. The first gated-on portion is generated during a first segment of the time slot and the first gated-off portion is generated during a second segment of the time slot, while the second gated-on portion is generated during the second segment and the second gated-off portion is generated during the first segment. Media access control (MAC) can be used to further define positions within time slots and provide error correction, power control, and the like. A preamble can be transmitted at an increased power level to facilitate acquisition.

A method for transmitting signals in a wireless network, comprising:

dividing a transmission time into M time slots;
and
repeating for each of the M time slots as a selected time slot,
dividing the selected time slot into N allocation intervals, each of the N allocation intervals having an assigned interval duration, each of the interval durations representing an assigned fraction of the selected time slot;
determining an assigned power level for each of the N allocation intervals, respectively;
assigning N different device pairs in the wireless network to the N allocation intervals, respectively;
and
transmitting information between the N different device pairs in respective ones of the N allocation intervals,
wherein for each of the N allocation intervals, the respective assigned power level is determined such that the respective assigned power level multiplied by the assigned fraction of the time slot is less than or equal to a threshold power,
wherein M is an integer greater than 1, and
wherein N is an integer greater than 1.
