Abstract: Embodiments of wireless communication devices (WCDs) and methods for cancelling signal interference in the WCDs are generally described herein. Some of these embodiments describe a WCD that includes a receiver to generate a received signal, which includes at least a first signal transmitted to the WCD by a network station that operates in a full-duplex mode while the WCD operates in a half-duplex mode. The WCD also includes a module to generate an interference cancellation signal for the received signal based on interference information obtained from at least the received signal. The interference information is associated with a second signal transmitted to the network station by an additional device. The first signal is transmitted while the second signal is transmitted. The first and second signals include the same radio-frequency (RF) carrier.

Abstract: This disclosure describes systems, methods, and computer-readable media related to employing rate adaptation in full-duplex communication. A first computing device may establish with a second computing device a full-duplex communication channel that may have a forward data transmission direction and a reverse data transmission direction. The first computing device may transmit to the second computing device a first data portion in the forward data transmission direction of the full-duplex communication channel at a default data transmission rate. The first computing device may receive a second data portion in the reverse direction of the full-duplex communication channel that may contain a forward channel quality information (CQI) associated with the forward data transmission direction. The first computing device may transmit to the second computing device a third data portion at a first data transmission rate, wherein the first data transmission rate is based at least in part on the forward CQI contained in the second data portion.

Abstract: Embodiments of a system and method for selecting a duplex mode for a service operating in a Wireless Network are generally described herein. In some embodiments, a mobile device may receive one or more traffic packets related to an establishment or a re-establishment of a service at the mobile device, and may select a duplex mode for the service. In some embodiments, the mobile device may be an IEEE 802.11 Station (STA). The mobile device may be configured to select full-duplex as the duplex mode when a delay requirement associated with the service is less than a predetermined delay threshold and when a calibration overhead associated with the mobile device or the service is less than a predetermined calibration overhead threshold. In addition, the mobile device may also be configured to select time-division duplex (TDD) or frequency-division duplex (FDD) as the duplex mode when the delay requirement is less than the delay threshold and when the calibration overhead is less than the calibration overhead threshold.

Abstract: A Spatial Multiple Access Uplink for Wireless LANs is generally described herein. A novel FD-MiMAC, protocol leverages full duplex functionality at the Access Point, can be incrementally deployed with current 802.11 Access Point and client devices, can be easily implemented by client devices in a distributed and contention based manner, and pairs users in uplink MU-MIMO to enhance system performance. A method for spatial multiple access uplink in a wireless local area network comprises announcing, by an Access Point (AP), its available remaining antenna capability, receiving, by the AP, a packet header frame transmitted by a winning client uplink contender, allocating, by the AP, uplink resources for the winning client uplink contender and immediately announcing its remaining antenna capability, and transmitting, by the AP, at the end of a winning client's transmission burst, an Acknowledge-to-All frame, whereby other clients may simultaneously restart contention for transmission of next frames.
