| 1. A method of preventing reception quality from being degraded due to a rapid transmission power change at a start of packet
data transmission to mobile stations in a transmitter of a base station, the method comprising the steps of:
determining, upon generation of a new packet data, whether the new packet data is successive to a previous packet data; and
transmitting a preamble with maximum available power for a predetermined time before transmitting the new packet data, if
the new packet data is not successive to a previous packet data;
wherein if the new packet data is not successive to the previous packet data, the base station transmits a preamble for a
predetermined time period before transmitting the new packet data in order to compensate for power consumption in a packet
data channel.
