| 20100113076 | Method and a Device for Reduced Interference in a Cellular Access System - A method for use in a cellular system comprising a plurality of base stations with corresponding cells, in which system the communication between users in a cell and the base station is divided into an up link period and a down link period, the method comprising letting a controlling node instruct the base stations regarding: a first point in time when the base station should start transmitting a control signal; a second point in time when the base station should start to listen for control signals from other base stations and measure their time of arrival and signal strength; a third point in time when the base station should cease listening for control signal; and a fourth point in time when the base station should transmit the measurements results to a receiving node in the system. | 05-06-2010 |
| 20100136989 | Method and Radio Base Station for Effective Spectrum Utilization - The present invention relates to radio communication in a cellular network and in particular to the sharing of a frequency spectrum with another network. The object is to enable robust communication in the shared band. The solution is to allocate a third band for communication in a cell. A L1/L2 control channel may be transmitted in the third band only, whereas data can be transmitted in the shared band. The L1/L2 control channel support the data communication in the shared band. The invention relates to a method and a radio base station. | 06-03-2010 |
| 20100248739 | Dynamic Frequency Band Allocation between Radio Communication Networks - The present invention relates to cellular communications and in particular to a frequency spectrum shared by two cellular networks. The object is flexible utilization of the spectrum. This is achieved by a method wherein a first of the networks occupies part of the shared spectrum in relation to the traffic load in the first network. The first network informs a second of the networks on the extent the shared spectrum is occupied, for the second network to be free to use the shared spectrum outside the occupied part. The invention also relates to a RRM unit arranged for carrying out the inventions, to a BSC and to a radio base station adapted for carrying out the method. One advantage is that spectrum can be lent from an old system when a new system is introduced. | 09-30-2010 |
| 20100254274 | Method of Monitoring Cells in Wireless Communication Systems - A wireless communication network automatically tests itself for sleeping cells. This is done by designing the base stations to regularly act as a terminal, contact its neighboring base stations and as a mobile perform a set of typical traffic cases. From the outcome of the traffic cases the probing base station detects neighboring base stations that cannot carry traffic. The information about sleeping cells is subsequently communicated from the base station to the operation and maintenance system. | 10-07-2010 |
