Abstract

a presente invenção refere-se a tecnologias de comunicação sem fio, e especificamente, a um dispositivo de terminal, um dispositivo de rede, um método para transmitir um sinal de referência de uplink, e um método para receber o mesmo. a presente invenção resolve o problema de ser incapaz de obter informações de uma portadora tais como características de canal de downlink se um sinal de referência de uplink não for transmitido sobre a portadora em um cenário de agregação de portadora. em um dispositivo de terminal, um módulo de transmissão transmite um sinal de referência de uplink para um dispositivo de rede sobre um primeiro subquadro de uplink de uma primeira portadora, em que a primeira portadora é uma portadora sobre a qual o terminal não transmite dados de uplink ou informações de controle de uplink em uma direção de uplink; e um módulo de processamento determina um primeiro relatório de espaço livre de potência phr, em que o primeiro phr é um phr da potência de transmissão do dispositivo de terminal sobre o primeiro subquadro de uplink ou um phr da potência de transmissão do dispositivo de terminal sobre o primeiro subquadro de uplink da primeira portadora. introduzindo uma portadora especial e transmitindo os sinais de referência de uplink sobre a portadora especial, um dispositivo de re-de pode obter informações tais como características de canal de down-link da dita portadora especial.
