Abstract

1/1 resumo “nó de rede e método no mesmo e estação rádio base e método na mesma para proteger os canais de controle de estação rádio base vizinha” trata-se de um nó de rede e um método realizado por um nó de rede para proteger canais de controle de uma rbs vizinha, em que o nó de rede e a rbs são operáveis em uma rede de comunicação de rádio com base em ofdm. uma rbs e um método realizados por uma rbs para transmitir canais de controle aos ues atualmente associados com a rbs em uma rede de comunicação de rádio com base em ofdm também são fornecidos. o método no nó de rede compreende determinar (220) pelo menos um subquadro dentre um número predeterminado de subquadros nos quais os canais de controle devem ser transmitidos com potência de transmissão reduzida em relação a uma potência de transmissão nominal; e informar (230) a rbs de qual subquadro(s) dentre o número predeterminado de subquadros nos quais os canais de controle devem ser transmitidos com potência de transmissão reduzida.
