Abstract

MéTODO DE ACESSO RANDÈMICO E DISPOSITIVO TERMINAL DE RADICOMUNICAçãO. Há divulgado um método de acesso randómico para estabelecimento de um canal individual entre um dispositivo terminal de radiocomunicação e um dispositivo de estação base em um curto tempo e um dispositivo terminal de radiocomunicação, executando o método de acesso randómico. Neste dispositivo, na etapa ST320, uma unidade de alocação de subcanal de RACH (211) aloca um pacote de transmissão introduzido de uma unidade de replicação (202) em uma subportadora arbitrária na abertura por tempo arbitrária de RACH, randomicamente. Na etapa ST330, uma unidade de alocação (21) julga se uma sobreposição é gerada no resultado de alocação obtido pela unidade de alocação de sub-canal de RACH (211). Quando a unidade de alocação (210) julga que uma sobreposição é gerada no resultado de alocaçao, a unidade de alocação (210) causa uma das unidades de alocação de sub-canal de RACH (211), que causou a sobreposição, realize mais uma vez a alocação da etapa ST320. Por outro lado, quando é feito um julgamento de que nenhuma sobreposição é gerada no resultado de alocação, a etapa ST340 é executada.
