Abstract
aspectos da presente invenção se referem em geral a um uso condicional dos sinais de referência para gerenciamento das comunicações de um ou mais equipamentos de usuário (ue) em um sistema de comunicação sem fio. os aspectos descritos incluem receber uma transmissão com um primeiro slot de subquadro e um segundo slot de subquadro, em que pelo menos um dentre o primeiro slot de subquadro e o segundo slot de subquadro tem um intervalo de tempo de transmissão (tti) de slot único. os aspectos descritos incluem ainda detectar um primeiro sinal de referência de demodulação (dm-rs) no primeiro slot de subquadro e um segundo dm-rs no segundo slot de subquadro. os aspectos descritos incluem ainda determinar quanto à demodulação do pelo menos um canal de downlink no primeiro slot de subquadro usando o primeiro dm-rs no primeiro slot de subquadro ou a demodulação de ambos o primeiro dm-rs no primeiro slot de subquadro e o segundo dm-rs no segundo slot de subquadro com base na existência da pelo menos uma condição.
