Abstract

técnicas para limitar decodificação cega para múltiplos pontos de transmissão-recepção com base em múltiplas dci. uma vez que as comunicações de múltiplos pontos de transmissão-recepção (trp) podem aumentar o número de candidatos de canal de controle de enlace descendente físico (pdcch) sem aumentar o número de células, novos limites para comunicações multi-trp podem ser definidos. um ue pode determinar uma capacidade de monitoramento de pdcch em todas as células de serviço de enlace descendente que pode ser responsável por células de múltiplos trps e para agregação de portadora e conectividade dupla usando um fator de multiplicação. além disso, o ue pode determinar um limite de um número de células de serviço com base na capacidade e na configuração das células de serviço. o ue pode determinar um limite total de candidatos de pdcch e elementos de canal de controle não sobrepostos (cces) para monitorar em um intervalo para um grupo de células e um limite por célula para células de trp único e para células de múltiplos trps com base no limite do número de células de serviço. como alternativa, os limites podem ser definidos por grupo de conjunto de recursos de controle (coreset).
