Abstract

INDICADOR DE PERFURAÇÃO DE DL DE CAMADA BAIXA (DCI OU CE DE MAC) PARA SINAIS DE REFERÊNCIA DE POSICIONAMENTO (PRS). Durante o posicionamento de um equipamento de usuário (UE), sinais de referência de posicionamento (PRS) de downlink (DL) transmitidos por um ou mais pontos de recepção de transmissão (TRP) em um sistema de comunicação sem fio podem ser antecipados ou perfurados por transmissões de prioridade mais alta, como tráfego de baixa latência ultra confiável (URLLC). Uma indicação de preempção de PRS (PI) pode ser fornecida para um UE por um TRP de serviço identificando um ou mais TRPs afetados por preempção. A PI de PRS ainda pode identificar o domínio de tempo e domínio de frequência das transmissões de PRS de DL antecipadas. A PI de PRS pode identificar o domínio de tempo, por exemplo, com base em um número de símbolos de PRS entre duas ocasiões de monitoramento, em que apenas símbolos de PRS que contêm sinais de referência de posicionamento de downlink associados ao grupo de TRPs são contados. A PI de PRS pode identificar o domínio de frequência identificando pelo menos uma de quatro ou mais sub-bandas de frequência das transmissões de PRS de DL antecipadas.
