20080293444 | Method For Power Control in a Wireless Station - The present invention relates to a power control method in a wireless station and a wireless station implementing said method. A transmission power is selected for transmission of a signal (e.g. a Request to Send control frame or a Clear to Send control frame) locally reserving a wireless medium for communication of data involving the wireless station based on Quality of Service requirements associated with said communication of data. Said signal is transmitted at said selected transmission power. | 11-27-2008 |
20090080376 | Power Control and Channel Selection in a Multi Channel Communication System - A method for allocating power and channels to connections in a multi-channel access based wireless communication system in which each connection is acting independently of the other. The quality of each channel of a connection is measured at successive time steps (n, n+1). The measurements from a previous time step (n) are used to allocate, in the following time step (n+1), an average power of all channels the connection uses as well as individual power settings in-between said channels. The average power is controlled using an outer fairness loop balancing the average channel power against average bit rate per channel. The individual power settings is controlled using an inner capacity loop allocating much power to good channels and restricted power to poor channels. Each loop has a respective target relation and the results of the loops are combined in order to determine transmission power in the next time step. The method is of distributed character and may execute on individual receiving nodes. Further, it may be applied in the up link or in the down link. The invention also relates to transmitting and receiving nodes provided with means for executing the method. | 03-26-2009 |
20100029292 | SELECTION OF RADIO RESOURCES IN A RADIO COMMUNICATIONS NETWORK - The present invention relates to a method and apparatus for selecting radio resources for transmission of data over a radio link to which at least two resource units have been allocated. At least one resource unit is selected out of the allocated resource units, wherein the selection is determined in dependence of the result of checking whether values of a quality measure of the allocated resource units fall within a certain range. | 02-04-2010 |

The set of cells comprises at least two cells. The fixed wireless terminal is a radio access network node comprised in the radio access network. The radio access network comprises a plurality of potential cells to which the packet data tunnels may be established, whereof said set of cells are part of the potential cells. The method comprising the steps of: Selecting the set of cells to use for a packet transmission, based on radio link quality between the fixed wireless terminal and each of the respective potential cells and establishing the at least two packet data tunnels, one individual packet data tunnel from the fixed wireless terminal through each of the respective cells in the selected set of cells. | 04-29-2010 |
20100111030 | Frequency Hopping Scheme for OFDMA System - Available bandwidth is divided into multiple sub-channels, and respective sub-bands containing one or more of these sub-channels are allocated to one or more users. A first frequency allocation is determined, and mathematical operators are used to determine at least one further frequency allocation from the first frequency allocation. A frequency hopping sequence is then determined, including the first frequency allocation, and the or each further frequency allocation. A network node may perform the allocation method, and a user equipment may operate using the allocated bandwidth. | 05-06-2010 |
