Abstract

vários aspectos fornecem recebimento de sinalização incluindo informações configuradas para indicar se deve ajustar uma estrutura de um subquadro de duplex de divisão de tempo (tdd). tal ajuste pode incluir ajustar um tempo ou subportadora alocada para um canal de controle, dados e/ou um sinal de referência, como um sinal de referência específico de equipamento de usuário (ue) (uers). o uers pode ser alinhado em tempo com um sinal de referência de demodulação (dmrs) de outro subquadro tdd. o uers pode ser utilizado para múltiplas entradas múltiplas saídas de múltiplos usuários (mu-mimo) de interligação quando o uers é ortogonal ao dmrs. vários outros aspectos fornecem comunicação de um ou mais tons nulos ou piloto em uma porção de dados de um primeiro subquadro de tdd. um ou mais tons nulos ou piloto podem ser usados para capturar interferência a partir de um segundo subquadro de tdd comunicado por outro aparelho. o primeiro subquadro de tdd pode ser comunicado pelo menos parcialmente simultâneo com o segundo subquadro de tdd.
