Uplink access for ambient power (AMP) clients

Abstract

This disclosure provides methods, components, devices and systems for uplink access for ambient power (AMP) devices. Some aspects more specifically relate to solicitation of a response from an AMP device in a shared medium subject to carrier sense type channel access. An access point or a reader device may transmit a control or trigger frame which solicits the response and indicates one or more resources associated with uplink access for the response in the shared medium subject to carrier sense type channel access. The AMP device may perform uplink access in the shared medium to transmit the solicited response. The type of control frame may depend on the purpose of the communication. The timing of the response to a unicast or multicast control frame may be based on the reception time of the control frame. The control frame may provide a reference time for uplink access for AMP devices.
