Abstract: A method for identifying association identifiers (AIDs) for multiple basic service sets (BSSs) supported by a first communication device is described. A reference identifier that indicates a fixed mapping of AIDs to BSS identifiers (BSSIDs) in a multiple-BSSID set is identified by a first communication device. The multiple-BSSID set includes BSSIDs of a first and second BSS. A management frame that includes a maximum BSSID indicator that indicates a maximum size of the multiple-BSSID set, the reference identifier, and a transmitter address of the management frame is generated for a receiver of the management frame to derive a first AID corresponding to the first BSS and a second AID corresponding to the second BSS based on the maximum BSSID indicator, the reference identifier, and the transmitter address. The management frame is transmitted to at least one second communication device associated with one of the first BSS and the second BSS.

Abstract: A method for simultaneous communication in a wireless local area network is described. A first control frame is transmitted by a first communication device to a plurality of communication devices, is duplicated across each of a plurality of sub-channels of an orthogonal frequency division multiplexing channel, and indicates that the communication devices are requested to simultaneously transmit respective control frames to the first communication device. Respective control frames are received, including second and third control frames from second and third communication devices, respectively, that are transmitted via a same sub-channel having a smallest bandwidth of the wireless local area network and indicate that at least some of the plurality of sub-channels are available. One of an orthogonal frequency division multiple access data unit and a duplicated legacy data unit is transmitted by the first communication device in response to the control frames via the available sub-channels.

Abstract: In aspects of access point association using trigger-based uplink single user transmission, a wireless network system includes a station device that detects an initial trigger frame communicated in the wireless network system, and the station device can communicate an association request to an access point to join the wireless network system. The access point can receive the association request from the station device and generate an association response as an acknowledgement to the association request. The acknowledgement aggregates an association response frame that includes an association identifier for the station device and a unicast trigger frame to initiate a trigger-based uplink single user (UL-SU) transmission from the station device. The access point can then communicate the acknowledgement to the station device.

The parameter module is configured to, via the PHY module, negotiate a first parameter with a second access point. A basic service set of the first access point overlaps a basic service set of the second access point. The first basic service set includes stations. The second basic service set includes one or more of the stations. The MAC module is configured to receive a first frame. The PHY module is configured to, based on the first parameter and during a joint transmission of the first frame by the first access point and the second access point, transmit the first frame to the stations according to a first address while the second access point transmits the first frame to the one or more stations according to the first address.

Abstract: Methods and systems are disclosed for performing contention based uplink (UL) orthogonal frequency division multiple access (OFDMA). The method may include receiving, from an access point using a channel, a first signal including an indication of a first time and a plurality of sub-channels of the channel. The method may include modifying a counter value in response to determining that the first time has been reached. The method may include selecting a sub-channel of the plurality of sub-channels in response to determining the counter value is equal to a threshold value. The method may include transmitting a second signal to the access point using the sub-channel. The methods and systems disclosed herein may be used by stations to associate with the access point.

Abstract: A communication device performs a clear channel assessment (CCA) procedure to determine whether the communication device can transmit in a shared wireless communication medium, wherein the communication device is in a first basic service set (BSS) associated with a virtual access point (AP) implemented by a physical AP, and wherein the first BSS corresponds to a first BSS identifier. Performing the CCA procedure includes: for first signals having the first BSS identifier or having one or more second BSS identifiers corresponding to other virtual APs implemented by the physical AP, comparing energy of the signals to a first threshold; and for first signals determined by the communication device to have one or more third BSS identifiers, wherein the one or more third BSS identifiers correspond to other physical APs, comparing energy of the signals to a second threshold lower than the first threshold.

Abstract: A communication device of a first wireless network determines that a first value of a first basic service set (BSS) color identifier is the same as a value of a second BSS color identifier corresponding to a neighboring second wireless network. In response, the communication device determines a second value of the first BSS color identifier. The communication device transmits one or more packets that each include i) an indication that the first BSS color identifier is changing, ii) the second value of the first BSS color identifier, and iii) a respective integer number of remaining beacon intervals corresponding to a start time when the second value of the first BSS color identifier will supersede the first value of the first BSS color identifier. Based on the start time, the communication device begins to use the second value of the first BSS color identifier with communications in the first wireless network.

Abstract: For a first group of devices having a first group size, a set of block allocations is selected from a codebook. A block allocation for the first group of devices is selected from the selected set of block allocations. A corresponding integer number of different orthogonal frequency division multiplexing (OFDM) tone blocks is assigned to each device of the first group of devices according to the allocation. An orthogonal frequency division multiple access (OFDMA) data unit to be transmitted to the first group of devices via the WLAN communication channel is generated using the assigned set of OFDM tone blocks. The OFDMA data unit includes a preamble portion and a data portion, the preamble portion having an index to the codebook that indicates i) the first group size, and ii) the selected block allocation.
