    Abstract: This disclosure describes methods, devices, and systems related to an OFDMA Distributed Channel Access. Devices are disclosed comprising: at least one processor; and at least one memory that stores computer-executable instructions, wherein the at least one processor is configured to access the at least one memory and execute the computer-executable instructions to identify a trigger frame received on the communication channel from the computing device. The at least one processor may determine an uplink frame to be sent to a computing device on a communication channel. The at least one processor may identify one or more random access resource allocations, wherein the one or more random access resource allocations are associated with the trigger frame. The at least one processor may assign a respective numerical value to each of the one or more random access resource allocations. The at least one processor may also select a numerical value based at least in part on a probability distribution. The at least one processor may also determine a particular resource allocation of the one or more random access resource allocations that corresponds to the numerical value. The at least one processor may also cause the uplink frame to be sent to the computing device using the particular resource allocation.

    Abstract: Systems and methods for frame addressing in DL MU-MIMO transmissions are described. In some embodiments, identifier information identifying receiving devices for a frame may be included in a header of that frame. In various embodiments, the identifier information may include a concatenation of respective identifiers for each of the plurality of receiving devices. In some other embodiments, the identifiers may include information identifying a pre-defined device group including several receiving devices. In some embodiments, the frame may include a medium access control (MAC) frame transmitted by an access point/personal basic service set control point (PCP/AP), and the recipient devices may include non-AP/non-PCP stations (STAs). In some such embodiments, a receiving STA address (RA) field or transmitting STA address (TA) field in a MAC header of the MAC frame may be used as a container for the recipient identifier information.

    Abstract: Some demonstrative embodiments include apparatuses, systems and/or methods of negotiating a range measurement protocol. For example, an initiator station may be configured to transmit a negotiation request message to a responder station and receive a negotiation response message from the responder station to negotiate a range measurement protocol to perform a range measurement procedure with the responder station, the negotiation request message including an initiator protocol element including an indication of one or more initiator range measurement protocols supported by the initiator station, the negotiation response message including a compatibility indication to indicate whether or not at least one of the initiator range measurement protocols is compatible with at least one responder range measurement protocol supported by the responder station; and based on the compatibility indication, select to perform the range measurement procedure with the responder station or to abort communication with the responder station.

    Abstract: Some embodiments relate to methods, computer readable media, and apparatus for resolving acknowledgements between associated and unassociated stations. An apparatus is disclosed including processing circuitry configured to decode responses to a random-access trigger frame, wherein one of the responses is a response from an unassociated station. The processing circuitry may be further configured to: encode an acknowledgement to acknowledge receipt of the response from the unassociated station, where the acknowledgement comprises an indication that the acknowledgement is for the unassociated station, and where the acknowledgement further comprises a media access control (MAC) address of the unassociated station in a field of the acknowledgement other than a field in a MAC header portion of the acknowledgement. The processing circuitry may configure the HE access point to transmit the acknowledgement.

    Abstract: Embodiments of fast steering timing and resource allocation are generally described herein. In some embodiments, a non-access point station (STA) decodes a fast steering timing signaling element (STSE) at a Narrow Band Control sub-Channel (NB-C-CH) and from an allocator device, the STSE indicating at least fast steering timing information, an identified Narrow Band Service sub-Channel (NB-S-CH), resource allocation information for the identified NB-S-CH, and connectivity information for the identified NB-S-CH, the identified NB-S-CH being selected from a plurality of NB-S-CHs. The STA exchanges packets in the NB-S-CH according to the resource allocation information and the connectivity information and based on the fast steering timing information. The STA encodes or decodes data associated with the exchanged packets.
