20100190520 | LINK ADAPTATION BY CHANNEL BUNDLING IN A WIRELESS COMMUNICATION SYSTEM - The present invention relates to a method of reducing interference in a communication system supporting multiple radio channel communication scheme and wherein a communication link can be established between a transmitter and a receiver. In the method the transmitter first determines ( | 07-29-2010 |
20100260046 | CONGESTION CONTROL IN A COMMUNICATION NETWORK BASED ON THE CSMA/CA PROTOCOL - The present invention relates to a congestion control method for a communication system supporting layered radio channel structure for communication between at least a first communication device and a second communication device, the layered structure comprising at least a physical layer and a medium access layer. The communication system is arranged to offer a first type of service with a first priority order and a second type of service with a second priority order, in the communication system messages comprising a preamble and a payload can be transmitted between devices, each message being separated by at least a period corresponding to a minimum allowable period between two messages. In the method the first communication device first (a) generates ( | 10-14-2010 |

20110026472 | REDUCING BEACON COLLISION PROBABILITY - The present invention relates to a method of reducing beacon collision probability in a communication network supporting control channels comprising beacon periods divided into beacon slots, each beacon period being followed by a contention period. In the method a communication device ( | 02-03-2011 |
20120106362 | DISTRIBUTED LEARNING METHOD FOR WIRELESS MESH NETWORKS - In a wireless mesh network, an algorithm is used by mesh points in the network to predict the success of and interference created by a new transmission opportunity. In particular, it is provided a method for mesh points, in a mesh network, to determine whether to transmit to another mesh point simultaneously while another transmission is taking place on the same communication link. A mesh point should not transmit to another mesh point if the mesh point's transmission interference disturbs a simultaneous transmission from another mesh point. Furthermore, a transmitting mesh point should not transmit to a receiving mesh point if the transmission will be disturbed at the receiving mesh point from interference from a simultaneous transmission from another mesh point. | 05-03-2012 |
20120106522 | DISTRIBUTED MEDIUM ACCESS PROTOCOL FOR WIRELESS MESH NETWORKS - This invention defines a medium access protocol for the support of mesh networking in wireless communications. It defines a phase for intra-cell and a phase for inter-cell traffic. During the inter-cell traffic a beacon phase is used for the reservation of transmissions. In this phase also information about the mesh topology is included and parallel transmission are supported. | 05-03-2012 |
