Abstract

resumo alocação de recurso físico para canais de controle de ul em sistemas de tdd adaptativa as modalidades desta invenção propõem métodos de alocação de recurso físico para canais de controle de ul incluindo pucch e prach em sistemas de tdd adaptativa. em um sistema de tdd adaptativa, há múltiplos tipos de configuração de ul-dl, por exemplo, configuração fechada (d) e sistema, configuração de referência de ul (mesma para configuração de sistema), configuração de referência de dl (diferente da configuração de sistema) e configuração real. se um ue de legado e um ue de eimta respectivamente seguirem a configuração de sistema e a configuração de referência de dl para harq-ack de dl de retorno e recursos de pucch correspondentes forem implicitamente determinados pelo índice de cce, uma colisão de recurso de pucch poderá acontecer, isto é, múltiplos pucchs serão transmitidos em um recurso único. o problema de colisão de recurso de pucch causará uma degeneração de performance de pucch, e precisa ser resolvido. algumas soluções são propostas na invenção para resolução deste problema.
