Abstract

transmissor, receptor e métodos para sinalização de controle de enlace descendente. trata-se de extensões de informações de controle de enlace descendente (dci) para suportar funcionalidades de rel-10 de 3gpp que compreendem extensões mínimas de formato dci 2b. em algumas modalidades, somente dois extra (20) são introduzidos para sinalizar classificação até, ao reutilizar o bit de identidade de encaminhamento (16) enquanto que ao mesmo tempo suporta dimensionamento de mu-mimo diferente para os casos importantes de classificação 1 e classificação 2. esse novo formato dci pode suportar, potencialmente, não somente transmissão de enlace descendente de célula única mas também algumas outras funcionalidades rel-10, por exemplo, comp ou retransmissão/hetnet.
