Abstract

vários fatores proporcionam a comunicação de um primeiro conjunto de sinais de referência de comunicação broadcasting (rss) em um primeiro subframe que inclui um canal de sincronização (sync) e comunicação de um segundo conjunto de rss de transmissão em um segundo subframe que segue o primeiro subframe. o segundo subframe pode seguir imediatamente o primeiro subframe. uma parte do canal sync pode incluir informação indicando uma configuração de rss de broadcast em um ou mais outros subframes. os rss de transmissão podem ser configurados para estimativa de erro de tempo, estimativa de erro de frequência e / ou estimativa de canal. aspectos adicionais e alternativos, formas de realização e características também são fornecidos aqui.
