Abstract: Methods and apparatus for providing wireless messages according to various tone plans can include a method of wireless communication. The method includes allocating a first allocation unit associated with a first tone plan having a first number of tones, for communication of one or more wireless messages by a wireless device. The method further includes allocating a second allocation unit, associated with a second tone plan having a second number of tones different from the first number of tones, for communication of one or more wireless messages by the wireless device. The method further includes selecting a combined tone plan for the wireless device based on at least the first tone plan and the second tone plan. The method further includes providing a wireless message for transmission by the wireless device according to the combined tone plan.

Abstract: Methods and systems for wireless communication are disclosed. In one aspect, a method includes generating device specific transmission control information for each of two devices, transmitting the transmission control information for each device over different frequencies, and transmitting data to each of the devices as part of a communication according to the respective transmission control information. In some aspects, the transmission control information for each device is encoded based on an identifier of the device. For example, in some aspects, an error detection value such as a cyclic redundancy check, is exclusive or'ed with an identifier of the device, such as an AID, PAID, or group identifier. The resulting value is transmitted along with the transmission control information. A device receiving the wireless frame may only be able to decode its own transmission control information, as the decoding is also based on the receiving device's identifier.

Abstract: Various aspects of the disclosure relate to communication using a data unit that includes at least one mid-amble. In some aspects, an apparatus may use mid-ambles for mobility scenarios (e.g., when the apparatus is moving outdoors). The disclosure relates in some aspects to signaling associated with the use of mid-ambles. In some aspects, an apparatus may signal whether it supports sending and/or receiving data with mid-ambles. In some aspects, an apparatus may signal whether a particular data unit includes at least one mid-amble. In some aspects, an apparatus may signal an indication of at least one mid-amble update interval. In some aspects, an apparatus may signal whether a mid-amble includes a short training field.

Abstract: Aspects of the present disclosure provide techniques and apparatus for deferral based on basic service set identification (BSSID) information. According to certain aspects, a method for wireless communications is provided. The method generally includes receiving, on a shared access medium, a packet having at least one deferral-related parameter and deciding whether to defer transmission on the shared access medium based, at least in part, on the deferral-related parameter. Another method may generally include generating a packet comprising at least one deferral-related parameter to be used by another apparatus for deciding whether or not the other apparatus should defer transmitting on a shared access medium and providing the packet to the other apparatus.
