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.

Abstract: Methods, systems, and devices are described for wireless communication at a device. A Long Term Evolution Unlicensed (LTE-U) device may transmit an enhanced preamble that may be understood by Wireless Local Area Network (WLAN) devices, in addition to conveying a characteristic that is detectable by receiving LTE-U devices. The transmitting LTE-U device may generate the enhanced preamble by generating a first training field and a second training field. The characteristic that is detectable by receiving LTE-U devices may be a phase shift between the first and second training fields. Additionally or alternatively, the characteristic may be a sequence or tone mapping of the first or second training field. In some cases, the transmitting LTE-U device may introduce a third training field to the preamble which serves as the characteristic.
