Abstract

INDICAÇÃO DE MATRIZ DE PRÉ-CODIFICAÇÃO PARA REPETIÇÕES DE CANAL FÍSICO COMPARTILHADO DE UPLINK. Vários aspectos da presente divulgação geralmente se referem à comunicação sem fio. Em alguns aspectos, um equipamento de usuário (UE) pode receber uma mensagem de informações de controle de downlink (DCI) que inclui um primeiro campo indicando um primeiro índice indicador de matriz de pré-codificador de transmissão (TPMI) e uma quantidade de camadas de transmissão e um segundo campo indicando um segundo índice de TPMI. O UE pode determinar uma primeira matriz de pré-codificação para transmitir um primeiro conjunto de repetições de uma transmissão de canal físico compartilhado de uplink (PUSCH) com base, pelo menos em parte, no primeiro índice de TPMI e na quantidade de camadas de transmissão, e uma segunda matriz de pré-codificação para transmitir um segundo conjunto de repetições da transmissão de PUSCH com base, pelo menos em parte, no segundo índice de TPMI e na quantidade de camadas de transmissão. Vários outros aspectos são fornecidos.
