According to one embodiment, a wireless communication device includes a transmitter configured to transmit a first frame including information to specify a plurality of frequency components; and controlling circuitry configured to determine whether a second frame is received via each of the plurality of frequency components. The transmitter is configured to transmit a third frame including first information concerning a first value range which is used to determine whether to respond to the first frame, the first value range being dependent on a number of frequency components via which the second frame has been received.

Disclosed is a method for operating a communication node supporting a low power mode in a wireless LAN. A method for operating a station, which includes a PCR and a WURx, comprises the steps of: allowing the WURx, which operates in a wake-up state, to receive a wake-up packet from an access point; transitioning an operating state of the PCR from a sleep state to the wake-up state when the wake-up packet is received; allowing the PCR, which operates in the wake-up state, to receive a data frame from an access point; and allowing the PCR to transmit, to the access point, a response to the data frame.

An access point manages a first wireless local area network (WLAN) in a 6 GHz radio frequency (RF) band and ii) a second WLAN operating in another RF band. The access point generates a physical layer (PHY) data unit to include a management frame having i) first information indicating first network parameters of the first WLAN, and ii) second information indicating second network parameters of the second WLAN. The AP transmits the PHY data unit in the other RF band to provide, to any client stations that are operating in the other RF band and that are also capable of operating in the 6 GHz band: the first information indicating the first network parameters of the first WLAN operating in the 6 GHz RF band to assist the any client stations that are operating in the other RF band with joining the first WLAN operating in the 6 GHz RF band.

Systems, methods, and devices provide multi-user communication between wireless devices. Methods include identifying, using processing elements of a software enabled access point, a plurality of wireless devices communicatively coupled to the software enabled access point, aggregating, using the processing elements, data associated with the plurality of wireless devices, and generating, using the processing elements, transmission instructions identifying transmission periods for the plurality of wireless devices. Methods also include generating, using the processing elements, a data frame based on the aggregated data, the data frame comprising a data payload that comprises the aggregated data and the transmission instructions.

Wireless communications comprises generating a trigger frame which has a first set of bits which directly indicates a resource unit (RU) arranged as a distributed RU is solicited to be transmitted in an uplink direction in a first frequency block and a second set of bits which directly indicates for one or more second frequency subblocks a spreading bandwidth of tones of the distributed RU or whether a second frequency subblock is a punctured subchannel. An access point (AP) transmits the trigger frame in a downlink direction to a non-AP station. The non-AP station generates and transmits in the uplink direction a Physical Layer Protocol Data Unit (PPDU) to the AP station with data modulated on the tones of the distributed RU based on the first set of bits and the second set of bits of the trigger frame.

A wireless communications protocol for enabling legacy (non-EHT) stations (STAs) to operate on the conditional link of the Soft AP MLD. Legacy devices can connect and setup link connections on the conditional link, and the scheduler is configured to allow legacy STAs to use the conditional link if there is no IDC interference issue at the soft AP MLD. This enhanced protocol utilizes either a cooperative HCCA schedule created for simultaneous transmission and reception over the basic link and conditional link, or an adaptive polling-based scheduling performed for the conditional link in response to the link status of the basic link.

Methods and apparatuses are related to multi-user parallel channel access (MU-PCA). For example, a wireless transmit/receive unit (WTRU) is provided that is one of the plurality of WTRUs operable to simultaneously communicate via a plurality of channels managed by an access point (AP). The WTRU includes a receiver configured to receive, from the AP, over at least one channel of the plurality of channels, a group poll (G-Poll) message that includes a resource allocation that indicates at least one allocated channel of the plurality of channels for the WTRU; and a transmitter configured to transmit an uplink request message, to the AP in response to the G-Poll message, over the at least one allocated channel of the plurality of channels, the uplink request message corresponding to uplink data the WTRU has for transmission to the AP.
