Abstract

os aspectos da revelação se referem a um dispositivo de transmissão, que pode sinalizar explícita ou implicitamente o uso de pré-codificação contínua para um cluster de bloco de recursos (rb). por exemplo, o dispositivo de transmissão pode indicar implicitamente que a pré-codificação contínua é aplicada a um cluster rb controlando-se dinamicamente um ou mais parâmetros de uma transmissão através daqueles rbs. ademais, quando a pré-codificação contínua é aplicada a um cluster rb, o dispositivo de transmissão pode sinalizar explícita ou implicitamente o controle dinâmico através de uma ou mais propriedades de transmissão, com um objetivo de maximizar os benefícios de tal pré-codificação contínua. outros aspectos, modalidades e recursos também são reivindicados e descritos.
