BROADCASTING SERVICE METHOD THROUGH PACKET DATA CHANNEL IN WIRELESS COMMUNICATION SYSTEM, ESPECIALLY CONCERNED WITH PROVIDING DEDICATED DATA SERVICE AND BROADCASTING SERVICE AT THE SAME TIME THROUGH PACKET DATA CHANNEL

摘要

PURPOSE: A broadcasting service method through a packet data channel in a wireless communication system is provided to transmit packet data for a broadcasting service and control information including an assigned user identifier therein, respectively, through a packet data channel and a packet data control channel, thereby stably supplying the broadcasting service at high speed. CONSTITUTION: A terminal receives data of a PDCH(Packet Data Channel) and data of a PDCCH(Packet Data Control Channel) every time interval(100), and decodes the received data of the PDCCH by using an MAC ID to obtain control information first(105). If the decoding for the PDCCH is successful, the terminal confirms whether the received data of the PDCH is retransmitted data through the control information(115). If not, the terminal decodes the received data of the PDCH to obtain packet data(120). The terminal decides whether a CRC error is generated from the packet data(140). If not, the terminal processes the packet data, and feeds back an acknowledgement through an R(Reverse)-ACKCH(Acknowledge Channel)(145).
