  • Patent number: 10609647
    Abstract: An apparatus for implementing power control for a radio device that has multiple radio transceivers operating in different bands, including sub-bands of a single frequency band. The device implements a power control protocol for communications between the device and a similar peer device. The device sets-up the power control protocol by generating a request to use one of the multiple bands to signal power control operations, and to use another one of the multiple bands to transfer data between the device and the peer device. The device sends the request to the peer device and receives a response. Based on the response, the device identifies a control channel band and a data channel band from among the multiple bands.

  • Publication number: 20200015167
    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.

  • Publication number: 20200008149
    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.

  • Publication number: 20190393934
    Abstract: Methods, computer readable media, and wireless apparatuses are disclosed for a TXOP duration field disable setting in a HE preamble, such as HE-SIG-A. An apparatus of a wireless device can include processing circuitry configured to decode a HE PPDU received from a second wireless device, the HE PPDU including a first TXOP duration field in a PHY portion of the HE PPDU. The processing circuitry can detect whether the TXOP duration field includes a disable flag based on bit values of the TXOP duration field. The disable flag can indicate absence of duration information in the TXOP duration field. Upon detecting the disable flag, a response HE PPDU can be encoded for transmission to the second wireless device. The response HE PPDU can include a second TXOP duration field with a disable flag within a PHY portion of the response HE PPDU.
