Abstract

MEDIÇÃO E RELATÓRIO DE INFORMAÇÃO DO ESTADO DO CANAL. Uma regra especifica uma relação de temporização entre uma configuração de medição que indica pelo menos um subquadro auxiliar para medir e uma configuração de relatório que indica pelo menos um subquadro em que reportar. Esta regra é usada pelo usuário, tanto o equipamento UE e uma rede de mapeamento entre um subquadro de downlink em que a informação do estado do canal é medida e um subquadro de uplink, em que informação do estado do canal é relatada. A rede pode configurar o UE com as configurações de medição e elaboração de relatórios por meio de sinalização dedicada ou transmissão. Se a configuração da medição é periódica e indica múltiplos subquadros de downlink para medir os resultados da regra para um mapeamento de downlink para subquadro de uplink, em que menos do que todos os múltiplos subquadros de downlink mapeiam para um subquadro de uplink; se aperiódica, a regra indica um único subquadro de downlink para medir.
