Abstract

de acordo com algumas modalidades, um método para uso em um equipamento de usuário (ue) operável para transmitir um sinal de referência de sondagem (srs) em uma pluralidade de portadoras compreende: obter uma indicação para realizar comutação baseada em portadora srs para uma portadora; adaptar um parâmetro para controle de potência de transmissão de enlace ascendente 5 em resposta à indicação obtida; e transmitir um sinal de enlace ascendente com o uso do parâmetro adaptado enquanto atende pelo menos um requisito de controle de potência de enlace ascendente predeterminado. de acordo com algumas modalidades, um método para uso em um nó de rede operável para receber um srs em uma pluralidade de portadoras compreende: enviar, para um ue, uma indicação para realizar comutação baseada em portadora srs para uma portadora; e receber, a partir do ue, um sinal de enlace ascendente com base 0 no parâmetro para controle de potência de transmissão de enlace ascendente adaptado em resposta à indicação enviada, em que o sinal de enlace ascendente atende pelo menos um requisito de controle de potência de enlace ascendente.
