Abstract: A first access point including a receiver, a transmitter, a feedback module, and a location determining module. The receiver receives a first frame from a client station. The transmitter transmits a second frame to the client station. The first and second frames are also received by second and third devices, which are located at predetermined locations. The feedback module receives a first feedback from the client station including times of departure and arrival of the first and second frames at the client station, and a second feedback from the second and third devices including times of arrival of the first and second frames at the second device and the third device. The location determining module determines a location of the client station based on the times of arrival and departure of the first and second frames at the first access point, the first and second feedbacks, and the predetermined locations.

Abstract: A method for communicating with an access point by a station. The station receives a first signal including an indication of a plurality of channels. The first signal is received from an access point. The station modifies a counter value in in response to receiving the first signal. The station further compares the counter value to a threshold value and selects a channel of the plurality of channels in response to determining the counter value corresponds to the threshold value. The station determines whether the selected channel is busy or idle. The station modifies the counter value in in response to determining that the selected channel is busy. The station transmits a second signal using the selected channel in response to determining that the selected channel is idle.

Abstract: In aspects of acknowledgement options for downlink multi-user transmission, a wireless network system includes an access point that can communicate a downlink multi-user transmission soliciting acknowledgement from one or more station devices. The access point can receive an association request or an operation mode change request frame from one or more of the station devices, and determine an acknowledgement option for each of the station devices that communicate the request to the access point. The access point can then use a multi-user transmission mode or a single user transmission mode for each of the station devices based on the acknowledgement option determined for each of the respective station devices.

Abstract: Aspects of the disclosure provide an apparatus for wireless communication. The apparatus includes a transceiver and a processing circuit. The transceiver is configured to transmit and receive wireless signals. The processing circuit is configured to detect an error of a previous scheduled transmission of data units from the apparatus to another apparatus. The other apparatus provides scheduled resources for transmission between the two apparatuses. Further, the processing circuit is configured to determine resources that are scheduled by the other apparatus for the apparatus to perform retransmission, and provide one or more of the data units in the previous scheduled transmission to the transceiver for retransmission using the scheduled resources.

Abstract: The present disclosure proposes systems and methods for performing spatial reuse using the following techniques at access points and stations. More specifically, the present disclosure relates to spatial reuse of medium with a spatial reuse opportunity announcement provided to STAs by an AP, opportunistic directional sensing performed by STAs, and a channel access method with a new backoff procedure performed by the STAs. An AP may provision a spatial reuse opportunity announcement in a beacon interval, and STAs may perform opportunistic directional sensing based on the announcement and perform channel access after performing opportunistic directional sensing.

Abstract: A first communication device generates a packet associated with acknowledgment of frames corresponding to multiple second communication devices. Generating the packet includes generating a frame that includes a field having respective acknowledgment information for the multiple second communication devices in respective subfields. The subfields have a plurality of different formats. The subfields are arranged within the field in groups of adjacent subfields such that each group includes only subfields of a same format and/or includes only subfields corresponding to second communication devices that have communicated to the first communication device a same set of supported formats of the subfields. The first communication device transmits the packet to the multiple second communication devices.

Abstract: Systems and methods are provided for performing multi-user transmissions across different segments of a transmission medium. A connection between a first access point and a plurality of stations is established; wherein a first station of the plurality of stations detects that a primary channel of communication between the first access point and the plurality of stations is being used for transmission by a second access point. The first access point allocates a transmission channel to the first station to communicate with the first access point. The first access point determines whether an acknowledgement from the first station is received. In response to determining that the acknowledgement has been received, the first access point allocates a resource unit to the first station using the transmission channel. In response to determining that the acknowledgement has not been received, the first access point reallocates the first station to a different transmission channel.
