Abstract
As modalidades da presente invenção fornecem um método de configuração de sinal de referência, um aparelho e um sistema. O método inclui: mapeamento de um sinal de referência de rastreamento de fase PTRS para um ou mais símbolos OFDM com base em informações sobre uma correspondência entre o PTRS e um ou mais de um esquema de modulação e codificação MCS, um subportador espaçamento SC, e uma largura de banda BW; e enviando um ou mais símbolos OFDM para o qual o PTRS é mapeado para um dispositivo de recebimento. Nas incorporações da presente invenção, uma correspondência entre o PTRS e o espaçamento do subportador ou o esquema de modulação e codificação ou a largura de banda é usada para indicar implicitamente um local de frequência de tempo do PTRS. Em comparação com a arte prévia, nenhuma indicação explícita é exigida, e os despesas gerais de sinalização são reduzidos.
