Abstract

"DISPOSITIVOS DE ESTAçãO DE BASE E DE ESTAçãO MóVEL PARA UM SISTEMA DE COMUNICAçãO DE ACESSO MúLTIPLO POR DIVISãO DE CóDIGO, E, PROCESSOS DE CONTROLE DE POTêNCIA EM UM DISPOSITIVO DE ESTAçãO DE BASE E DE ESTAçãO MóVEL PARA UM SISTEMA DE COMUNICAçãO DE ACESSO MúLTIPLO POR DIVISãO DE CóDIGO." Trata-se de um dispositivo de controle de potência para um sistema de comunicação de CDMA que utiliza diferentes tipos de códigos de espalhamento. No dispositivo de controle de potência para o dispositivo de estação de base, o primeiro gerador de canal gera um primeiro sinal de canal espalhando primeiros dados de entrada (DATA1) com um código ortogonal e um segundo gerador de canal gera um segundo sinal de canal espalhando segundos dados de entrada (DATA2) com um código quase ortogonal. O segundo sinal de canal possui um ganho mais elevado que o do primeiro sinal de canal. Um primeiro dispositivo de controle de ganho (17) controla a potência do primeiro sinal de canal e um segundo dispositivo controlador de ganho (18) controla a potência do segundo sinal de canal. O dispositivo de adição (20) adiciona o primeiro sinal de canal ao segundo sinal de canal, e um dispositivo espalhador (21) espalha um sinal de saída do dispositivo adicionador com um código de ruído pseudo-aleatório (Pseudo-Random Noise - PN). A estação de base transmite uma mensagem de solicitação de resposta para uma estação móvel através do segundo canal, e retransmite a mensagem de solicitação de resposta após aumentar uma potência de transmissão do segundo canal quando não é recebida uma mensagem de resposta da estação móvel."BASE STATION AND MOBILE STATION DEVICES FOR A MULTIPLE ACCESS COMMUNICATION SYSTEM BY CODE DIVISION, AND, POWER CONTROL PROCESSES IN A MOBILE STATION AND MOBILE STATION WITH A MOUNTED STATION WITH A MOISTURIZED STATION. CODE DIVISION. " It is a power control device for a CDMA communication system that uses different types of spreading codes. In the power control device for the base station device, the first channel generator generates a first channel signal by spreading first input data (DATA1) with an orthogonal code and a second channel generator generates a second channel signal by spreading second input data (DATA2) with an almost orthogonal code. The second channel signal has a higher gain than the first channel signal. A first gain control device (17) controls the power of the first channel signal and a second gain control device (18) controls the power of the second channel signal. The adding device (20) adds the first channel signal to the second channel signal, and a spreading device (21) spreads an output signal from the adding device with a pseudo-random noise code (Pseudo-Random Noise - PN) . The base station transmits a reply request message to a mobile station via the second channel, and retransmits the reply request message after increasing a transmit power from the second channel when a reply message is not received from the mobile station.
