  • Publication number: 20150358067
    Abstract: A method for associating a new end-station (end-STA) with a relay access point (R-AP) in a relay transmission. An assignment of a new identifier is transmitted to the new end-STA, wherein traffic indication map indications for the new end-STA in a beacon from the R-AP follows the transmission of the new identifier assignment. A message is sent to a root access point (AP), the message including an indication of a number of information fields in the message and at least one information field, each of the at least one information fields including an identifier of one end-STA associated with the R-AP. An acknowledgement is received from the root AP on a condition that the root AP correctly receives the message and associates an identifier of the end-STA with an identifier of the R-AP.

  • Publication number: 20150271732
    Abstract: A method and apparatus are disclosed for enabling very high throughput (VHT) communications. A wireless transmit and receive unit (WTRU) may receive, from an access point (AP), a management frame comprising VHT capabilities information. The VHT capabilities information may comprise an indication of support for reception via non-contiguous channels. The WTRU may transmit, on a condition that reception via non-contiguous channels is supported, at least one data packet, to the AP, via multiple non-contiguous channels. The multiple non-contiguous channels may be used simultaneously.

  • Publication number: 20150256245
    Abstract: A method and apparatus may be used in Very High Throughput (VHT) Wireless Local Area Network (WLAN) management actions. Management action frames such as VHT Action frames may be used to implement VHT features in WLANs. Extensions to 802.11 Action frames may be used to support VHT features and provide backward compatibility. VHT Management Actions may be supported with VHT Action frames and VHT extensions to 802.11 Action frames in various categories such as Direct Link Setup (DLS), Public, Spectrum Management and high throughput (HT). An access point (AP) or a wireless transmit/receive unit (WTRU) may indicate VHT capability by way of signaling.

  • Publication number: 20150223163
    Abstract: A method and apparatus may be used for assigning groups of stations in wireless communications to one or more groups. Groups may be assigned by an access point (AP) based on information received from a station (STA). Group information may be signaled to each station and a group identifier may be indicated in a frame. The group information may be applied to a performance enhancement, for example power savings for the station, wherein the station enters a power saving mode on a condition that the station determines that it is not a member of the group.

  • Publication number: 20150092720
    Abstract: A method and apparatus that applies medium access control (MAC) transmission opportunity (TXOP) protection for multiple mode operation in a WLAN system. In particular, MAC mechanisms are defined to support multiple mode CTS frames, and multiple mode CF-End frames sent by the AP, each in a format appropriate for the corresponding mode which may also apply to a single mode. MAC mechanisms permit truncation of TXOP duration for releasing the unused portion of the TXOP when no further data for transmission is available. Release of unused protected TXOP is possible for both protected AP transmissions and STA transmissions.

  • Publication number: 20140369338
    Abstract: A method and system for improving responsiveness in exchanging management and control frames in a wireless local area network are disclosed. An initiator sends a frame (action frame, management frame, CSI frame, control frame, or data frame) to a responder. Upon correctly receiving the frame, the responder sends a response frame to the initiator instead of directly sending an acknowledgement (ACK) packet. The responder preferably accesses the wireless medium to send the response frame in a short inter-frame spacing (SIFS). With this scheme, a long delay associated with having to contend for the wireless medium to send the response frame is avoided and therefore, the responsiveness and timeliness of the feedback mechanism is significantly enhanced. The response frame may be piggybacked on or aggregated with another packet.
