Abstract

métodos, sistemas, e dispositivos para comunicação sem fio são descritos. um método em um equipamento de usuário (ue) inclui receber sinalização que indica uma configuração de agregação de portadora (ca) (tendo portadoras configuradas para transmissões de dados de ul e enlace descendente (dl)) e uma configuração de enlace ascendente (ul) auxiliar (tendo portadoras configuradas para transmissões de sinal de referência de ul). o método também inclui receber uma atribuição de recurso em uma portadora de dl da configuração de ca, e transmitir um sinal de referência de sondagem aperiódico (a-srs) usando uma ou mais portadoras da configuração de ul auxiliar com base pelo menos em parte na atribuição de recurso recebido. um outro método é executado por um ue tendo uma configuração de ca e uma configuração de a-srs, incluindo recebendo uma atribuição de recurso em uma portadora de dl na configuração de ca, detectando um acionador para transmitir um a-srs, determinando recursos de ul da configuração de a-srs para transmitir o a-srs, e transmitindo o a-srs nos recursos de ul determinados.
