Abstract: Access to unlicensed bands is typically preceded by a LBT or CCA mechanism, through which the transmitter determines the presence of ongoing transmissions in the same channel. Specifically, an AP or STA (prior to transmitting) senses the channel, and transmits only if the channel is adjudged to be idle. As mandated by the current IEEE 802.11 standard, the energy detected in the channel is compared with a predefined CCA threshold (signal detect threshold is −82 dBm and energy threshold is −62 dBm for 20 MHz OFDM transmission). This creates an RF-energy based guard zone around each transmitter and hence prevents any other transmitter from reusing the medium. To fully leverage simultaneous transmit and receive capability at an AP, it is desirable for the AP to simultaneously send downlink data to a STA while receiving UL data from another STA. However, with traditional CCA methods, the downlink transmission would be blocked.

Abstract: Mobile platform power management is an important problem especially for battery-powered small form factor platforms such as smartphones, tablets, wearable devices, Internet of Things (TOT) devices, and the like. A wake-up packet scheduler, a packet manager and a padding manager interact and cooperate to insert at least one wake-up packet on a sub-channel in a padding area after a data frame, the wake-up packet usable by a low-power wake-up radio in, for example, an IEEE 802.11 wireless communication environment.

Abstract: Mobile platform power management is an important problem especially for battery-powered small form factor platforms such as smartphones, tablets, wearable devices, Internet of Things (IOT) devices, and the like. A low-power wake-up radio cooperates with a mobility manager which is configured to receive information from one or more sensors and determine a mobility management frame. The mobility management frame specifies transmitter operation, such as a number and time interval over which to transmit a number of wake-up packets, which are usable by the low-power wake-up radio to control main radio operation in the wireless communications device.
