Abstract: A method for transmit time offset in a UL-MU-MIMO system monitors respective transmit powers, over a wireless channel, for a plurality of stations in the system. A respective transmit time offset is determined for each station in response to the respective transmit power of each station. A poll exchange sequence is initiated in which the transmit time offsets are transmitted to each respective station. An access point can then receive data from the stations at times adjusted by the respective transmit time offsets.

Abstract: Embodiments of a high efficiency subchannel selective transmission (HE SST) access point (AP) and an HE SST station (STA) are generally described herein. The HE SST AP may determine a temporary primary channel for an HE SST STA. The HE SST AP may communicate with the HE SST STA in a plurality of channels that includes the temporary primary channel and further includes a primary channel. The HE SST AP may determine trigger-enabled target wake time service periods (TWT SPs) for exchange of frames between the HE SST AP and the HE SST STA on the temporary primary channel. The trigger-enabled TWT SPs may be determined to not overlap with target beacon transmission times (TBTTs) at which beacon frames that include delivery traffic indication maps (DTIMs) are to be sent on the primary channel by the HE SST AP.

Abstract: Methods, devices, and systems for retransmission of wake-up signals from a first station to a second station over a wireless network are disclosed. In some aspects, a wake-up signal is encoded for transmission to the second station. While the first station is waiting for an acknowledgment of the wake-up signal from the second station, the second station may retransmit the wake up signal and/or encode a packet for transmission to a third station. In some aspects, whether the wake-up signal is retransmitted is based in part, on at least one of whether a number of timeout events for wake-up signals transmitted to the second station exceeds a maximum timeouts threshold, whether a number of wake-up signals transmitted to the second station exceeds a maximum wake-up signals threshold; or whether a maximum predetermined elapsed time since a first wake-up signal was transmitted to the second station is exceeded.

Abstract: Methods, apparatus, and computer-readable media are described to encode, by a first station, duty cycle timing for transmission to a second station via a primary connectivity radio. A wake-up radio (WUR) receiver (WURx) is enabled to receive a transmission based upon the duty cycle timing of the WURx when the primary connectivity radio is in a doze state from a perspective of the second station. A wake-up packet, received from the second station, is decoded and received by the WURx. The WURx receives a WURx transmission when in an WURx awake state. The primary connectivity radio is enabled based upon decoding the wake-up packet.
