Abstract

transmissão de informações de controle de uplink em canais físicos de controle de uplink usando diferentes potências de transmissão. métodos, sistemas e dispositivos para comunicação sem fio são descritos. um equipamento de usuário (ue) pode receber uma transmissão de agendamento de mensagem, pelo ue, de informações de controle de uplink (uci) em um recurso do canal físico de controle de uplink (pucch). o ue pode receber uma indicação de que o ue está programado para transmitir a uci no recurso pucch tanto para um primeiro ponto de transmissão - recepção (trp) quanto para um segundo trp. o ue também pode receber um primeiro conjunto de parâmetros de controle de potência de uplink para transmitir a uci para o primeiro trp e um segundo conjunto de parâmetros de controle de potência de uplink para transmitir a uci para o segundo trp. o ue pode transmitir a uci para o primeiro trp e para o segundo trp no recurso pucch, com base no primeiro conjunto e no segundo conjunto de parâmetros de controle de potência de uplink e sem uma indicação de feixe do canal de controle de uplink.
