Abstract
Staggered Multi-User (MU) uplink in an Ambient Power (AMP) Backscatter Device (BKD) group may be provided. A transmitter AP may determine to receive uplink data from an AMP BKD group and then transmit a session initialization message to a receiver AP instructing the receiver AP to receive the uplink data from the AMP BKD group. The transmitter AP may receive an initialization response from the receiver AP indicating the receiver AP will receive the uplink data. The transmitter may transmit an AMP BKD initialization signal to the AMP BKD group indicating to the AMP BKD group to perform scattering without collisions. The transmitter AP may then transmit an excitation transmission for the AMP BKD group to perform scattering.
