Methods and systems for frequency multiplexed communication in dense wireless environments
First Claim
1. A method of high-efficiency wireless frequency division multiplexing, comprising:
- receiving, at a first wireless device from an access point, a reference signal for reserving a wireless medium including a set of wireless frequencies available for use by both the first wireless device and a second wireless device, the reference signal including an indication of a power level at which at least one of the first and second wireless devices should transmit communications; and
transmitting, from the first wireless device to the access point, a first communication on a first subset of the set of wireless frequencies, the first communication being transmitted at least partially concurrent with a second communication transmitted on a second subset of the set of wireless frequencies from the second wireless device to the access point, and the first and second subsets of the set of wireless frequencies being mutually exclusive subsets of the set of wireless frequencies.

Abstract
Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes exchanging, at an access point, at least one frame reserving a wireless medium with at least one of a first and second wireless device. The method further includes receiving a first communication on a first set of wireless frequencies from the first wireless device. The method further includes receiving a second communication, at least partially concurrent with the first communication, on a second set of wireless frequencies from the second wireless device. The method further includes transmitting at least one acknowledgment of the first and second communication. The first set and the second set are mutually exclusive subsets of a set of wireless frequencies available for use by both the first and second wireless device.

11. An apparatus configured to perform high-efficiency wireless frequency division multiplexing, comprising:
-
a processor; a receiver, in connection with the processor and configured to receive, at the apparatus from an access point, a reference signal for reserving a wireless medium including a set of wireless frequencies available for use by both the apparatus and a wireless device, the reference signal including an indication of a power level at which at least one of the apparatus and the wireless device should transmit communications; and a transmitter, in connection with the processor and configured to, in response to receiving the reference signal, transmit, from the apparatus to the access point, a first communication on a first subset of the set of wireless frequencies, the first communication being transmitted at least partially concurrent with a second communication transmitted on a second subset of the set of wireless frequencies from the wireless device to the access point, and the first and second subsets of the set of wireless frequencies being mutually exclusive subsets of the set of wireless frequencies. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
