  • Patent number: 10080238
    Abstract: A method and apparatus are disclosed for enabling high-efficiency communication in wireless local area network (WLAN) systems. A station (STA) may receive an Uplink Priority List (UPL) from an access point (AP). In one example embodiment, a STA may send a request for prioritized access to an AP. The STA may then receive an ordered queue of STAs granted contention free prioritized access in a predetermined time interval, which may be referred to as the Exclusive Priority Access (EPA) period. The STA may then determine whether it is identified in the ordered queue of STAs granted prioritized access. The STA may then access a medium such as a Carrier Sense Multiple Access (CSMA) wireless medium associated with the IEEE 802.11 network, in turn with other STAs in the ordered queue per the queue order during the predetermined time interval using an inter-frame spacing, thereby enabling contention free access.

  • Patent number: 9961577
    Abstract: A beacon signal may be provided with data extensions. The data extensions permit additional information to be provided by the beacon signal, thereby reducing the traffic overhead of the network. The data extensions further permit handoffs and handoffs based on offset values. A Measurement Request field corresponding to a beacon request contains a measurement duration value and channel number for which the request applies. The beacon request permits a scan mode. In Active Scan mode, the measuring station (STA) transmits a probe request with a broadcast SSID. In Passive Scan mode, the measuring STA passively receives on the specified channel and return a beacon report containing one information element for each STA from which it detects a beacon or probe response. In Beacon Table mode, the measuring STA returns a beacon report containing the current contents of its beacon table without performing additional measurements.

  • Publication number: 20170325122
    Abstract: A method and apparatus may be used for network management via MAC measurements. The measurements may include WTRU uplink traffic loading measurement, and an AP service loading measurement. The measurements may be applicable to at least to layers 1 and 2 as applied to, for example, 802.11k in the context of OFDM and CDMA 2000 systems, but may be applicable to other scenarios as well. A method for determining and transmitting congestion information may be provided for a Wireless Local Area Network (WLAN) system. The method and apparatus may be used for managing congestion when congestion is detected. The method and apparatus may be used in wireless systems that use a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism. The methods may be implemented in wireless transmit/receive units (WTRU)s and access points (AP)s of various forms.

    Abstract: A subscriber unit for automatic repeat request mechanisms and related methods are disclosed. The subscriber unit may comprise transmitting a single carrier frequency domain equalization (SC-FDE) signals using a plurality of hybrid automatic repeat request (ARQ) mechanisms. The plurality of hybrid ARQ mechanisms may use a stop and wait architecture. Further, each of the plurality of hybrid ARQ mechanisms may transmit in a different time interval and each time interval includes at least one time slot. The subscriber unit may receive downlink data signals using hybrid ARQ and may receive acknowledgments (ACKs)/negative acknowledgments, wherein the ACK/NAKs may be received in a time period between the downlink transmissions.

  • Patent number: 9729384
    Abstract: A method and wireless communication system may be used for transferring management information. An access point (AP) may transmit a management information base (MIB) information request including a category field and an action details field to a wireless transmit/receive (WTRU). In response to receiving the information request, the WTRU may determine whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU may compile management information stored in a MIB located in the WTRU and transmit a MIB information report to the AP. The MIB may list a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements. The AP may include a MIB for storing MIB information of the WTRU. The AP may transmit the stored MIB information of the WTRU in response to a request.

  • Publication number: 20160262025
    Abstract: Disclosed herein are methods and apparatus for the communication of wireless data using diverse radio access technologies (RATs) in Television Band (TVBD) frequencies. An architecture for communicating wireless data in TVBD frequencies may include one or more network nodes that perform functions related to the coordination of channel quieting across multiple diverse RATs. Channel quieting may be performed across multiple diverse RATs by using temporary channel reassignments, by aggregating wireless transmit/receive units (WTRUs) that use a particular RAT onto the same channel, and/or via other techniques.
