Abstract: Long Range Low Power (LRLP) for narrowband loT within (coexistence) the IEEE 802.11 standard. A mixed mode preamble is proposed consisting in a legacy 802.11 preamble part (20 MHz bandwidth) followed by an LRLP preamble part (narrowband) and LRLP data. This can be seen also as a concatenation of the legacy preamble and a Greenfield LRLP packet. Indication within HE-SIG A field of the legacy preamble that a LRLP packet is following. Multiple selectable configurations of the LRLP preamble (STF, LTF, SIG and repetitions of LTF) are proposed. Single User (SU) or Multi-User (MU) LRLP configuration.

Abstract: Resource allocation signaling in a high efficiency wireless local area network (WLAN) is disclosed. An access point (AP) may generate a resource unit (RU) size indicator in a first WLAN signaling field, the RU size indicator decodable by a set of stations. The AP may also generate a common user field in a second WLAN signaling field, such that a size of the common user field may be based on the RU size indicator of the first WLAN signaling field. The AP may generate a station-specific field in the second WLAN signaling field, such that a position of the a station-specific field corresponds to one or more RUs associated with the a station-specific field. The AP may then transmit a WLAN preamble that includes the first WLAN signaling field followed by the second WLAN signaling field.
