    摘要: This disclosure describes methods, apparatuses, and wireless stations related to waking up low power radios. In particular, a wireless station is disclosed that may identify a first management frame from a first wireless station a first management frame from a first wireless station. The wireless station may cause to allocate one or more group identifications (IDs) to the first wireless station. The wireless station may cause to generate a bitmap corresponding to the allocation of the one or more group IDs to the first wireless station. The wireless station may cause to send a second management frame to the first wireless station of one or more wireless stations, wherein the second management frame comprises the bitmap.

    摘要: Disclosed is a drone rotor cage. The drone rotor cage may include a motor housing, a plurality of spars, and a plurality of ribs. The plurality of spars may extend from the motor housing. Each of the plurality of spars may have a spar height and a spar thickness. The spar height may be greater than the spar thickness. Each of the ribs may extend from a respective one of the plurality of spars. Each of the plurality of ribs may have a rib height and a rib thickness. The rib height may be greater than the rib thickness. The plurality of spars and the plurality of ribs may define a space sized to allow a rotor to spin freely when the rotor cage is attached to a drone.

    摘要: Modulation circuitry is configured to generate a phase modulated signal having an output frequency that corresponds to a local oscillator (LO) signal divided by N.5. A phase locked loop (PLL) is configured to generate an LO signal having a frequency that is N.5 times the output frequency. Pulse circuitry configured to generate, based at least on a value of N, an edge signal including a pulse aligned with a positive edge of the LO signal and a pulse aligned with a negative edge of the LO signal. The edge signal is used to generate the phase modulated signal.

    摘要: 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.

    摘要: This disclosure relates to a beamforming controller for a beamforming transmitter device, the beamforming controller comprising a control element configured to: activate a first configuration state of a plurality of configuration states for a control channel, each configuration state indicating a beam direction of the control channel; control a beam switching of the control channel from the first configuration state to a second configuration state based on a beam direction of the control channel according to the first configuration state; and retransmit signaling of the beam switching based on a beam direction of the control channel according to both the first and the second configuration state if an acknowledgement to the beam switching is null, not received, missing or received in error.
