20140056163 | Systems and Methods for Nearby Channel Measurement - System and method embodiments are provided for nearby channel measurement. The embodiments enable identifying stations that are hidden from one another. In an embodiment, a method in a wireless access point (AP) for identifying channel quality between a first and second group of STAs associated with the AP includes transmitting a first packet to the first group of STAs, wherein the first packet comprises information on measurement time window within which the first group of STAs is to measure a received signal; transmitting scheduling information to the second group of STAs, wherein the scheduling information indicates a time to send a reference packet during the measurement time window; and receiving a measurement report from the first group of STAs after the measurement time window, wherein measurement report includes information on received signal quality at the first group of STAs of a signal transmitted by the second group of STAs. | 02-27-2014 |
20140092746 | System and Method for Response Frame Type indication - Embodiments are provided for indicating response frame types according to response frame durations in a wireless network. The embodiments include defining a plurality of response frame types in accordance to different transmission durations. The different response frame types are assigned corresponding indication values. When transmitting a current frame to a receiver entity, a transmitter entity selects a response frame type from the defined response frame types, and indicates in the current frame the selected response frame type using the assigned indication value. When a third entity receives the current frame, the third entity waits for a time period about equal to a predefined inter-frame and backoff time before transmitting a new frame. Upon determining that the indication value in the current frame is for sending a response frame, the third entity also waits an additional time period about equal to the transmission duration of the indicated response frame type. | 04-03-2014 |
20140126360 | System and Method for WiFi Offload - Embodiments are provided for enabling WiFi offload by integrating the WiFi and cellular networks operations at a radio access network level. The embodiments include a WiFi network component configured to determine whether to send over a cellular air interface a packet designated for WiFi according to a predefined rule. If the rule is met, the WiFi network component sends the packet to a cellular network component over the cellular air interface. The cellular network component is configured to process the received packet for cellular transmission, and transmit the packet using the cellular air interface to a receiver device. The predefined rule comprises at least one of sending the packet using the cellular air interface if the packet belongs to a predefined packet type, if the packet has a size below a predefined threshold size, and if the nature of the destination address for the packet is a broadcast address. | 05-08-2014 |
20140160930 | Systems and Methods for Packet Relaying - System and method embodiments are provided for packet relaying. The embodiments enable reduced network traffic. In an embodiment, a method in a wireless network component for packet relaying includes transmitting a first data packet comprising data to a relay station, wherein the first data packet comprises an identification (ID) of the target wireless device wherein the data packet is intended for a target wireless device, wherein the relay station is configured to forward the data in the first data packet to the target wireless device without sending an acknowledgement back to the wireless network component; receiving a second data packet transmitted by the relay station; and determining whether a receiver ID of the second data packet corresponds to the target wireless device, wherein the wireless network component considers the transmission successful if the receiver ID of the second data packet corresponds to the target wireless device. | 06-12-2014 |
20140293978 | System and Method for Pre-Association Discovery - A method for operating a seeker device includes generating a first seeker truncated hash output from a sought service name, and generating a second seeker truncated hash output from the sought service name, wherein the first seeker truncated hash output and the second seeker truncated hash output are uncorrelated. The method also includes transmitting a first request message including the first seeker truncated hash output, and receiving a first response message from an advertiser device, the first response message including a second advertiser truncated hash output generated from an advertised service name, wherein the first seeker truncated hash output matches a first advertiser truncated hash output generated from the advertised service name. | 10-02-2014 |
20140321436 | Systems and Methods for Efficient Channel Synchronization - System and method embodiments are provided for efficient channel synchronization. The embodiments enable a reduction in a stations power consumption and reduce network overhead for transmitting synchronization frames by refraining from sending the synchronization frame when it is not needed. In an embodiment, a method in an access point (AP) for synchronizing a station (STA) associated with the AP includes sending, by the AP, a first management frame that indicates a time slot that is allocated for the STA and sending a synchronization frame at a boundary of the time slot allocated for the STA if the AP determines that a channel is idle at the boundary of the time slot allocated for the STA and if the time slot that is allocated for the STA is longer than a first threshold value. | 10-30-2014 |
20140337950 | Method and Apparatus for Secure Communications in a Wireless Network - A method and apparatus for secure communications between an access point and a station in a wireless network is provided. The station receives a first message from the access point in the wireless network, the first message includes a first hashed service set identifier (SSID) generated by the access point by performing a first hash function on an SSID associated with the access point. The station generates a second hashed SSID by performing the first hash function on an SSID known by the station, determines whether the second hashed SSID matches the first hashed SSID. When the second hashed SSID matches the first hashed SSID, the station sends a second message to the access point. | 11-13-2014 |
20140376519 | System and Method for Detecting and Resolving Conflicts - A method for operating a first device includes transmitting a conflict query frame including a first address field containing a first locally assigned identifier associated with the first device, wherein the conflict query frame further includes a second address field and has a structure of a first legacy frame, and determining if a conflict notification corresponding to the conflict query frame is received within a specified time interval after transmitting the conflict query frame. The method also includes discontinuing use of the first locally assigned identifier if the conflict notification is received within the specified time interval, and continuing use of the first locally assigned identifier if the conflict notification is not received within the specified time interval. | 12-25-2014 |
20150078352 | System and Method for OFDMA PS-Poll Transmission - A method for communicating in a wireless system includes receiving a trigger frame including a paging bitmap, and resource allocation information indicating a location of a resource pool for transmitting a packet, and determining if the station is permitted to transmit the packet in accordance with the paging bitmap. If the station is permitted to transmit the packet, the method also includes determining a location of a network resource in the resource pool in accordance with an identifier of the station, and transmitting the packet at the location of the network resource. | 03-19-2015 |
