Abstract: Systems, methods, and devices for low overhead paging in a wireless communications network are described herein. In one aspect, a wireless communications device comprises a processor and a transmitter. The processor is configured to compress a bitmap of a paging message to obtain a compressed paging message. The bitmap is associated with a plurality of receiver identifiers, and each of the plurality of receiver identifiers associated with at least one receiver of a set of receivers. The compressed bitmap comprises a block bitmap and a plurality of sub-block bitmaps. Each bit of the block bitmap comprises a logical OR of a subset of the bitmap, and each sub-block bitmap corresponds to a bit of the block bitmap. The transmitter is electronically coupled with the processor and configured to transmit the compressed paging message to at least one receiver.

This disclosure introduces devices, methods, and systems to implement an additional power save with ultra low power (PS-ULP) mode that further reduces power consumption. In one aspect, a method of communicating a power management mode of a station on a wireless network is disclosed. The method includes transmitting by a station a first message on the wireless network, the first message indicating one of at least three power management modes, wherein the indication is communicated in a power management portion of a frame control field of a media access control header. The power management portion comprises more than one bit; and operating the station in a power management state in accordance with the indicated power management mode.
