Embodiment Construction

[0047] Detailed descriptions regarding the illustrative embodiments will now be described with reference to the various figures. While the description provides detailed examples of possible implementations, it should be noted that these details are intended to be illustrative and not to limit the scope of the application.

[0048]A wireless local area network (WLAN) can have multiple operating modes, such as infrastructure basic service set (BSS) mode and independent BSS (IBSS) mode. A WLAN in infrastructure BSS mode may have an access point (AP / PCP) for the BSS. One or more stations (STAs) may be associated with the AP / PCP. The AP / PCP can access or interface to a Distributed System (DS) or other type of wired / wireless network that sends traffic to and from the BSS. Traffic to STAs from outside the BSS may arrive through the AP / PCP, which may deliver the traffic to the STAs. Traffic from STAs to destinations located outside the BSS may be sent to the AP / PCP, which may deliv...

Abstract

Systems, methods, and instrumentalities are disclosed for adaptation of multiple input multiple output (MIMO) mode in mmW Wireless Local Area Network (WLAN) systems. A first station (STA) may receivea mode change request from a second STA. The mode change request may indicate a mode change for a MIMO mode, a polarization mode, and / or an orthogonal frequency-division multiple access (OFDMA) mode.The mode change request may include one or more STA fields. The one or more STA fields may include a STA field associated with the first STA. Each of the one or more STA fields may include a MIMO modesubfield, a polarization mode subfield, and / or an OFDMA mode subfield. The first STA may change the MIMO mode, the polarization mode, and / or the OFDMA mode, for example, based on the mode change request. The first STA may send a mode change response to the second STA.

Description

[0001] cross reference [0002] This application claims the benefit of US Provisional Application 62 / 365,115, filed July 21, 2016, and US Provisional Application 62 / 367,298, filed July 27, 2016, both of which are incorporated herein by reference. Background technique [0003] A wireless local area network (WLAN) can have multiple operating modes, such as an infrastructure basic service set (BSS) mode and an independent BSS (IBSS) mode. A WLAN in infrastructure BSS mode may have an access point (AP) for the BSS. One or more wireless transmit receive units (WTRUs), such as stations (STAs), may be associated with the AP. The AP may access or interface to a Distributed System (DS) or other type of wired / wireless network that sends traffic to and from the BSS. Traffic originating outside the BSS and destined for STAs can arrive through the AP, which can deliver the traffic to the STAs. In some WLAN systems, STA-to-STA communication may occur. In some WLAN systems, APs can play ...
