In an example embodiment of the invention, a method comprises: receiving, at an apparatus, one or more access node broadcast frames, wherein said broadcast frames comprise: assignment information on assignment of one or more assigned access slots; and contention indication indicating whether contention is to be performed in order to access said slots; learning at the apparatus, by considering said assignment information, of a slot, of said assigned access slots, assigned to the apparatus; learning, at the apparatus, by considering said contention indication, whether contention is to be performed in order to access the slot assigned to the apparatus; and accessing, at the apparatus, a medium during the slot assigned to the apparatus. | 09-11-2014 |
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 |
20150071180 | COMMUNICATION EFFICIENCY - There is provided a method, comprising: receiving, by a target node of a wireless access network, a signal from a first source node; determining the angular sector in which the first source node is located with respect to the target node; responding to the signal by both transmitting a first message omni-directionally and transmitting a second message directionally towards the angular sector; and establishing a first resource reservation on a frequency channel at least partly on the basis of transmitting the first message and the second message, wherein the first resource reservation is for performing directional data transfer with the first source node. | 03-12-2015 |
20150078259 | Interference Avoidance between Overlapping Wireless Networks - This document discloses a solution for reducing interference between wireless networks. According to an aspect, a method comprises: acquiring, by an access node of a first wireless network from at least one node of the first wireless network, information on at least one interfering node of a second wireless network; generating, by the access node, mapping information between the node of the first wireless network and said at least one interfering node; and causing, by the access node, transmission of the mapping information to another access node of the second wireless network. | 03-19-2015 |
