Abstract

métodos, sistemas e dispositivos para comunicação sem fio são descritos. equipamento de usuário (ue) utilizando agregação de portadora melhorada (eca) pode identificar um limite no qual o número de processos de realimentação de estado de canal (csf) é capaz de suportar. o ue pode transmitir uma indicação deste limite para uma estação base, que pode configurar o ue para relatório de estado de canal, e enviar gatilhos de relatório de estado de canal de acordo com o limite indicado. a determinação do ue do limite para o número de processos de csf pode ser com base em várias configurações de antenas de transmissão ou recepção. um único gatilho pode corresponder a relatórios que cobrem múltiplos subquadros e/ou portadoras de componentes. a estação base também pode dispor a configuração de relatório de estado de canal para reduzir o número de pico de relatórios de estado de canal que os processos de ue durante cada subquadro. o ue pode também determinar que um número de processos de estado de canal necessário para suportar relatório de estado de canal em um subquadro excede sua capacidade. o ue pode então priorizar os processos de estado de canal e/ou pode transmitir um ou mais relatórios não correntes.
