Abstract: Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes exchanging (1210), at an access point (104, 204A, 204B, 204C, 304A, 304B, 304C, 3040, 504), at least one frame reserving a wireless medium with at least one of a first and second wireless device. The method further includes receiving (1220) a first communication on a first set of wireless frequencies from the first wireless device. The method further includes receiving (1230) 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 (1240) 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.

Abstract: In order to address the issue of increasing bandwidth requirements that are demanded for wireless communications systems, different schemes are being developed to allow multiple user terminals to communicate with a single access point by sharing the channel resources while achieving high data throughputs. With limited communication resources, it is desirable to reduce the amount of traffic passing between the access point and the multiple terminals. For example, when multiple terminals send uplink communications to the access point, it is desirable to minimize the amount of traffic to complete the uplink of all transmissions. Thus, there is a need for an improved protocol for uplink transmissions from multiple terminals. Methods and apparatus for acknowledgment of multiple user uplink are provided. In one aspect, a method of wireless communication includes receiving a first wireless message from a first station at least partially concurrently with receiving a second wireless message from a second station, generating a first acknowledgment message in response to receiving the first wireless message, generating a second acknowledgement message in response to receiving the second wireless message, and transmitting the first acknowledgment message to the first station at least partially concurrently with transmitting the second acknowledgement message to the second station.

Abstract: A method, an apparatus, and a computer-readable medium for wireless communication are provided. In one aspect, the example method may include receiving a data frame including a Medium Access Control, MAC, header or a physical layer, PHY, header, wherein the MAC header or the PHY header of the data frame includes transmit power related information corresponding to a second device. The transmit power related information includes at least one of a maximum transmit power, a power backoff per modulation and coding scheme, MCS, information, or an actual transmit power. The example method further includes selecting, by the first device based on the transmit power related information, a first modulation and coding scheme for scheduling an uplink transmission with the second device in accordance with the first modulation and coding scheme.

Abstract: Systems, methods, and devices for high-efficiency wireless frequency division multiplexing are provided. A method includes receiving, at a first wireless device, a reference signal from an associated access point, the reference signal indicative of a time of joint transmission with at least a second wireless device. The method further includes transmitting a first communication to the access point based on the reference signal, the communication utilizing a first subset of wireless frequencies available for use. The first communication is concurrent with a second communication, from the second wireless device, utilizing a second subset of wireless frequencies, the second subset excluding the first subset.
