Abstract

um método de suportar transmissão de sinal de referência de sondagem (srs) aperiódico de enlace ascendente em redes de comunicação sem fio de acesso assistido licenciado (laa) é fornecido. em um aspecto inédito, uma estação base pode configurar cada ue com um id de grupo por meio de sinalização rrc, e então usar dci para sinalizar para o grupo para transmitir srs no símbolo sc-fdma correspondente. um novo rnti específico de célula é introduzido para a dci de grupo. em uma primeira modalidade, a dci compreende uma lista de ids de grupo, cada um indicando um id de grupo para transmissão srs no símbolo sc-fdma correspondente no uppts. em uma segunda modalidade, a dci compreende um número de símbolos sc-fdma no uppts e um valor de deslocamento do id de grupo para transmissão srs. o método proposto pode ativar grupos diferentes de ues em múltiplos símbolos sc-fdma em um modo flexível.
