MATCHING SUBCARRIER POWER IN A BROADBAND NETWORK COLLOCATED WITH A NARROWBAND NETWORK

摘要

According to the invention, a first broadband network divided into sectors and a second narrowband network have collocated cells and a common wide frequency band. The interferences produced by the first network on the second network are reduced for a carrier-threshold ratio for the allowable interference with reception in the second network. For example, a base station (BSBB,nc) in a given cell (CBB,nc) of the first network attenuates, by means of an attenuation parameter, the transmission power of each subcarrier that is adjacent to a carrier of one of the groups allocated to preselected cells (CNB,i) of the second network located in a sector (Sns) of the given cell and on levels (L0 to Ll-1) starting from the given cell (CBB,nc). The attenuation parameter is low for a level near the given cell.
