20140071959 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR COEXISTENCE OF WIRELESS NETWORKS - Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: receiving by a short-range access point in a basic service set, a beacon from a long-range access point in an overlapping basic service set, indicating a beginning and ending of a first quiet interval for short-range stations associated with the short-range access point; and transmitting by the short-range access point, a broadcast control frame, notifying the long-range access point of a second quiet interval for long-range stations associated with the long-range access point, the broadcast control frame further notifying the short-range stations associated with the short-range access point that they may access and transmit data during the second quiet interval. | 03-13-2014 |
20140126461 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR RELAY OPERATION IN WI-FI NETWORKS - Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: determining, by a wireless relay device, a first time window allocated for a first network, allowing first maximum transmit power for packet transmissions; and determining, by the wireless relay device, a second time window allocated for a second network, wherein the second time window is allowed for transmissions also within the first network, but only with second maximum transmit power that is lower than the first maximum transmit power. | 05-08-2014 |
20140153415 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR SIGNALING FOR SECTORIZED BEAM OPERATION IN WIRELESS NETWORKS - Method, apparatus, and computer program product embodiments configure channel access windows in overlapping network environments. An example method embodiment comprises: transmitting, by an access node, a measurement request to an associated wireless device, to perform measurements of signals received from other access nodes to which the device is not associated, the device being a member of a group of devices based on transmission by the access node to the device, of a directional beacon frame; receiving from the device, a measurement response comprising information on a directional message with an access node identifier of another access node to which the device is not associated; and determining a time window that may be used by devices that are members of the group, for transferring data between members of the group and the access node, based at least partly on the measurement response. | 06-05-2014 |

20140269628 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR OVERLAPPING BSS COORDINATION OF MACRO/PICO WI-FI NETWORKS - Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: receiving, by an access node of an access network, a frame from an overlapped access network, indicating time restrictions for reserving a wireless medium for the access network; and coordinating, by the access node of the access network, transmissions by members of the access network, to comply with the time restrictions for reserving the wireless medium for the access network. | 09-18-2014 |
20140334387 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR PROTECTING SHARED TRANSMISSION OPPORTUNITY - Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: receiving, by a first apparatus, a request-to-send frame for a transmission opportunity from a second apparatus; transmitting, by the first apparatus, a first clear-to-send frame for a shared transmission opportunity to the second apparatus; receiving, by the first apparatus, a second clear-to-send frame as response to the first clear-to-send frame from a third apparatus; receiving a data frame from the second apparatus during the shared transmission opportunity; and forwarding the data frame to the third apparatus during the same shared transmission opportunity. | 11-13-2014 |
20140335871 | METHOD, APPARATUS, AND COMPUTER PROGRAM PRODUCT FOR ENABLING NAV PROTECTION FOR RESTRICTED ACCESS WINDOW - Embodiments of the invention provide signaling mechanisms for wireless networks composed of a large number of stations. An example method embodiment comprises: receiving, by a station in an access network, a frame from another station in the access network or from an overlapped access network, indicating time restrictions for reserving a wireless medium, the frame including an indication in a first portion of the frame, indicating the presence of the time restrictions for reserving the wireless medium; and decoding, by the station, at least a second portion occurring after the first portion of the received frame, to determine the time restrictions for reserving the wireless medium, in response to the indication. | 11-13-2014 |
