Abstract

trata-se de métodos, sistemas e dispositivos para comunicação sem fio. um equipamento de usuário (ue) pode detectar o tamanho de uma carga para relatar retroinformações de solicitação de repetição automática híbrida (harq) para transmissões em um conjunto de portadoras de componentes (ccs) e pode determinar se uma solicitação de programação (sr) e/ou um relatório de informações de estado de canal periódicas (p-csi) está presente. o ue pode comparar um tamanho de uma mensagem de controle de enlace ascendente, a qual pode incluir um tamanho de carga de harq e uma carga para a sr ou o relatório de p-csi, com um limiar para selecionar um formato de controle de enlace ascendente. o formato de controle de enlace ascendente selecionado pode ser associado a um grande número de ccs se a mensagem de controle de enlace ascendente tiver uma carga tamanho acima de um limiar. o ue também pode usar uma configuração para transmitir dois ou mais relatórios de p-csi durante um subquadro para ccs de uma configuração de agregação de portadoras (ca). os relatórios de p-csi são previstos para transmissão durante um dado subquadro.
