Abstract

resumo acúmulo separado ue ajuste de potência de transmissão em sistema de tdd adaptativa um método de acúmulo separado em controle de potência de circuito fechado em sistemas de tdd adaptativa é proposto. um ue obtém informação de configuração de uma estação base em um sistema de tdd adaptativa. cada quadro de rádio compreende uma pluralidade de subquadros, que são configurados em dois ou mais conjuntos de subquadro. o ue recebe um comando de controle de potência de transmissão (tpc) em um subquadro de enlace descendente. o ue determina um estado de ajuste de controle de potência para um subquadro de enlace ascendente i com base no comando de tpc. o estado de ajuste de controle de potência de subquadro i é acumulado a partir de um estado de ajuste de controle de potência de um subquadro de enlace ascendente j anterior, onde subquadro i e subquadro j pertencem ao mesmo conjunto de subquadro. em uma modalidade, subquadro j é o mais próximo subquadro de enlace ascendente anterior no que diz respeito ao subquadro de enlace ascendente i.
