Abstract: PROBLEM TO BE SOLVED: To obtain an efficient power controllable communication system by making each user terminal extract data from its allocated time slot in those frames indicating that a slot includes data in accordance with setup information and a user packet flag. SOLUTION: A dedicated downlink channel time frame comprises, for instance, sixteen time slots. Downlink data is transmitted through a data channel in a repetition time frame and downlink setup information is transmitted through a control channel because a user terminal shows from which time slot data should be extracted. Each frame of a data channel includes a user packet flag that indicates whether or not each time slot in a frame includes data. Each user terminal extracts data from its allocated time slot in those frames in accordance with setup information and a user packet flag.

Abstract: SE EXPONE UN SISTEMA DE COMUNICACIONES DE ACCESO MULTIPLE POR DIVISION EN EL TIEMPO, EN QUE LOS DATOS DEL ENLACE DESCENDENTE SE TRANSMITEN A TRAVES DE UN CANAL DE DATOS EN TRAMAS DE TIEMPO REPETIDAS, CONTENIENDO CADA UNA SERIE DE INTERVALOS DE TIEMPO. LA INFORMACION DE CONFIGURACION DEL ENLACE DESCENDENTE SE TRANSMITE A TRAVES DE UN CANAL DE CONTROL PARA INDICAR DESDE QUE INTERVALO DE TIEMPO DEBERA EXTRAER LOS DATOS EL TERMINAL DE USUARIO. CADA TRAMA EN EL CANAL DE DATOS INCLUYE UNA BANDERA DEL PAQUETE DE USUARIO PARA INDICAR SI CONTIENE DATOS O NO LA TRAMA EN CADA INTERVALO DE TIEMPO. CADA TERMINAL DE USUARIO ES SENSIBLE A LA INFORMACION DE CONFIGURACION Y A LAS BANDERAS DEL PAQUETE DE USUARIO, PARA EXTRAER LOS DATOS DESDE SU INTERVALO DE TIEMPO ASIGNADO EN AQUELLAS TRAMAS EN QUE EL INTERVALO INDIQUE QUE CONTIENE DATOS.

Abstract: A time division multiple access communication system is disclosed, in which down link data are transmitted over a data channel in repeated time frames each containing a plurality of time slots. Down link set up information is transmitted over a control channel to indicate from which time slot a user terminal should extract data. Each frame on the data channel includes a user packet flag to indicate whether or not each time slot in the frame contains data. Each user terminal is responsive to the set up information and to the user packet flags to extract data from its assigned time slot in those frames which the slot is indicated to contain data.
