Abstract:
System and method of using an AP to individually controlling RTS/CTS duration thresholds for multiple STAs in a WLAN. In response to a STA's association request, the AP determines a duration threshold specific to the STA and encloses this information in an association request response for transmission to the STA. By using a broadcast frame, the AP may instruct multiple STAs to uniformly update their stored duration thresholds. For example, if the duration threshold field in the beacon frame is set to 0, the multiple STAs preserve their current duration thresholds; if the field is set to a non-zero value less than 1023, the multiple STAs all update their duration thresholds to the non-zero value; if this field is set to 1023, the multiple STAs disable the RTS/CTS transmissions. Based on a current threshold and pertinent policies, an STA can decide whether to initiate an RTS/CTS transmission sequence.
Abstract:
A device and method for multicasting data in a wireless network. The method includes receiving multicast data at a specific node of the wireless network, the multicast data including a multicast acknowledgement request; and determining by the specific node whether or not the specific node is requested to send an acknowledgement to the multicast acknowledgement request. Also, a device and method for multicasting data in a wireless network. The method includes transmitting multicast data, the multicast data including a multicast acknowledgement request, the multicast acknowledgement request including information configured to enable a specific node of the wireless network to determine whether or not the specific node is requested to send an acknowledgement to the multicast acknowledgement request.
Abstract:
A method and device for communicating in a contention-based communication network. According to an embodiment, the method includes obtaining, by a transmitter, an access to a channel during a transmission opportunity (TXOP) and transmitting, by the transmitter, a contention free (CF)-End frame to truncate the TXOP if the transmitter has no more data that the transmitter can send that fits within the TXOP, wherein the CF-End frame includes a duration field indicating a time required to complete the truncation of the TXOP.
Abstract:
An apparatus and method of transmission opportunity in a mesh network is disclosed. A beacon timing from a receiver MP is received. The beacon timing includes a beacon reception timing of a received beacon frame that is received by the receiver MP from a neighboring MP of the receiver MP. A transmission opportunity is determined in order not to be extended across the beacon reception timing.
Abstract:
There is provided a procedure for wireless network management and a station supporting the procedure. In the procedure, non-AP station which wants to us a traffic filter service (TFS) transmits a TFS request message including one or more TFS request elements for defining information about the requesting traffic filters to an access point (AP). And, the non-AP station receives, from the AP in response to the first TFS request message, a TFS response message including one or more TFS response elements for defining information about the status of the requesting traffic filters.
Abstract:
A method and device for communicating in a contention-based communication network. The method includes upon an early termination of a previously obtained transmission opportunity (TXOP) for communications with one of a mobile device and a base station, transmitting a contention free end (CF-End) frame to the base station for further broadcasting to the network by the base station. Also, a method and device for communicating in a contention-based communication system. The method includes receiving in a base station a first contention free end (CF-End) frame from a first mobile device indicating an early termination of a transmission opportunity (TXOP) previously obtained by the first mobile terminal for communications between the first mobile device and one of the base station and a second mobile device; and omnidirectionally broadcasting a second CF-End frame with a duration field having a value equal to zero.

Abstract:
The present disclosure relates to a method and apparatus for beamformed transmission in a wireless local area network. According to one aspect of the present disclosure, a method for transmitting a Physical layer Protocol Data Unit (PPDU) frame to a plurality of stations (STAs) by an Access Point (AP) in a wireless local area network may be provided. The method may include transmitting a SIGNAL field of the PPDU frame, the SIGNAL field including beamforming information indicating whether beamforming is applied to respective data units of the PPDU frame, and transmitting the data units of the PPDU frame, the data units being individually beamformed or not beamformed according to the beamforming information.
Abstract:
A method of processing a multicast frame in a wireless local area network (WLAN) and an apparatus supporting the method are provided. The method comprises receiving, at a station, a unicast frame from an access point (AP), the unicast frame including an unicast address indicating a single station which receives the unicast frame, receiving a multicast frame from the AP, the multicast frame including a group address indicating a group of stations which receives the multicast frame, determining whether the unicast frame is duplicated with the multicast frame, and discarding the multicast frame if the unicast frame is duplicated with the multicast frame.
Abstract:
Provided are a Tunneled Direct Link Setup (TDLS) establishment method for a TDLS initiator and a station supporting the establishment method. In the establishment method, a requesting Non-AP QSTA transmits a TDLS setup request frame via an access point(AP) to an intended peer Non-AP QSTA. And, the requesting Non-AP QSTA receives a TDLS setup response frame via the AP from the intended peer station in response to the TDLS setup request frame. And, the requesting Non-AP QSTA transmits a TDLS setup confirm frame via the AP to the intended peer station in response to the TDLS setup response frame.
