  • Publication number: 20190387472
    Abstract: A wireless communication system and method. The system includes processing circuitry, and a transceiver coupled to the processing circuitry. The processing circuitry includes logic to generate a wake-up packet addressed to another wireless communication system and including a legacy preamble portion and a wake-up portion, the legacy preamble portion modulated according to a first modulation rate. The wake-up portion is modulated according to a second modulation rate lower than the first modulation rate and includes information to wake-up the other wireless communication system. The transceiver system is to transmit the legacy preamble using a first transmit power level, and to transmit the wake-up portion using a second transmit power level higher than the first transmit power level by a predetermined amount such that an average received power of the wake-up portion is equal to an average received power of the legacy portion at the third-party station.

  • Publication number: 20190364597
    Abstract: Methods and devices are described for providing wireless stations (STAs) with two sets of enhanced distributed channel access (EDCA) parameters. Legacy EDCA parameters that are for single user (SU) operations and may be used by both high-efficiency (HE) STAs and legacy STAs without multi-user (MU) capability. MU EDCA parameters are defined to be more restrictive than legacy EDCA parameters in favoring MU operations. Embodiments are described that define sets of rules for regulating how STAs capable of both SU and MU uplink operations can use the different sets of EDCA parameters.

  • Publication number: 20190335311
    Abstract: Described herein are mechanisms to inform a first Neighbor Awareness Networking (NAN) device as to whether or not a second NAN device is connected to a dynamic frequency selection (DFS) master and/or whether the second NAN device is listening to the same DFS master as the first NAN device. In order for NAN client devices to operate in the 5 GHz band and be DFS compliant, all such devices that are communicating in a NAN peer-to-peer manner must either maintain association with a DFS master or must listen to the same DFS master for channel information.

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.
