Abstract

interferência ou puncionamento intermitente pode ser identificada, quer seja por um equipamento de usuário (ue) ou por uma estação base. em resposta, um esquema de proteção pode ser aplicado para proteger as comunicações a partir da interferência ou puncionamento intermitente. o esquema de proteção pode incluir o uso de intercalação de tempo e de frequência dos blocos de código nas comunicações. o esquema de proteção pode incluir também a modificação do esquema de modulação e codificação (mcs), taxa de codificação, índice de matriz de pré-codificação (pmi), ou indicador de categoria (ri) usado nas comunicações. o esquema de proteção também pode incluir o uso de um código de verificação de paridade de baixa densidade (ldpc) universal na transmissão das comunicações.
