Abstract

DISPOSITIVOS DE TRANSMISãO E DE CONTROLE DE POTêNCIA PARA UM\A ESTAçãO BASE E PROCESSOS DE DIVERSIDADE DE TRANSMISSãO E DE CONTROLE DE POTêNCIA EM UMA ESTAçãO MóVEL EM UM SISTEMA DE COMUNICAçãO. Um dispositivo de controle de potência para uma estação móvel em um sistema de comunicação CDMA incluindo uma estação base que transmite um sinal de tráfego via uma de pelo menos duas antenas e transmite um sinal de canal comum via uma outra antena. O dispositivo compreende um receptor para receber os sinais de canal comum e de tráfego transmitidos via uma antena; um medidor de potência de interferência para medir potência de uma saída de sinal de interferência do receptor; um medidor de potência de canal comum para medir potência da saída de sinal de canal comum do receptor; um medidor de potência de canal de tráfego para medir potência da saída de sinal de tráfego do receptor; um gerador de bit de controle de potência para gerar um bit de controle de potência para um canal de tráfego desligado que transmitiu o sinal de canal comum operando a potência dos sinais piloto e de interferência; e um multiplexador para multiplexar o bit de controle de potência para um canal de ligação reversa.TRANSMISSION AND POWER CONTROL DEVICES FOR A BASIC STATION AND POWER TRANSMISSION AND CONTROL DIVERSITY PROCESSES IN A MOBILE STATION IN A COMMUNICATION SYSTEM. A power control device for a mobile station in a CDMA communication system including a base station that transmits a traffic signal via one of at least two antennas and transmits a common channel signal via another antenna. The device comprises a receiver for receiving common channel and traffic signals transmitted via an antenna; an interference power meter for measuring power from a receiver interference signal output; a common channel power meter for measuring power of the receiver's common channel signal output; a traffic channel power meter for measuring the power of the receiver's traffic signal output; a power control bit generator for generating a power control bit for an off traffic channel that has transmitted the common channel signal operating the power of the pilot and interference signals; and a multiplexer for multiplexing the power control bit to a reverse link channel.
