Abstract (en)

[origin: EP2271156A1] The invention relates to a method to avoid interference between signals transmitted by at least two different base stations over cognitive Pilot Channels (CPC) to UEs located in contiguous cells of wireless telecommunication network, each cell comprising a plurality of meshes, the transmission power of said signals being adjustable to different levels between a minimum level and a maximum level. The method according to the invention comprises a step consisting of synchronizing said base stations so that they do not transmit signals with their respective maximum transmission power levels simultaneously.
