Upgrading of resources in a telecommunications network

   
   

The inventive idea is to send in the same cell on one channel several signals and to cause different radio frequency characteristics to the signals received on the same channel. The different characteristics of signals are brought about e.g. by modulating the signals in different ways or by sending the signals from different points, whereby the different signals will experience different radio channels. Owing to the different characteristics, the signals can be distinguished from one another by a joint detection, interference cancellation method. In the downlink direction from the base transceiver station to the mobile station and in the uplink direction from mobile station to the base transceiver station it is often advantageous to use different methods.

A idéia inventive é emitir na mesma pilha em uma canaleta diversos sinais e causar características diferentes da freqüência de rádio aos sinais recebidos na mesma canaleta. As características diferentes dos sinais são trazidas sobre por exemplo modulando os sinais em maneiras diferentes ou emitindo os sinais dos pontos diferentes, por meio de que os sinais diferentes experimentarão as canaletas de rádio diferentes. Devido às características diferentes, os sinais podem ser distintos de um outro por uma deteção comum, método do cancelamento de interferência. No sentido do downlink da estação baixa do transceptor à estação móvel e no sentido do uplink da estação móvel à estação baixa do transceptor é frequentemente vantajoso usar métodos diferentes.
