Transmitting/receiving apparatus and method for packet data service in a mobile telecommunication system
First Claim
1. A method of determining the transmission format of packet data between a first format and a second format longer than the first format based on channel state values received from a mobile station, comprising the steps of:
- (a) sequentially storing received channel state values;
(b) calculating the differences between all adjacent channel state values;
(c) summing the differences calculated between all adjacent channel state values;
(d) comparing the sum with a predetermined threshold; and
(e) determining the transmission format of packet data according to whether the sum is greater than the predetermined threshold.

Abstract
There are provided a transmitting/receiving apparatus and method for packet data service in a mobile telecommunication system. To determine the transmission format of packet data between a first format and a second format longer than the first format based on at least one channel state value received from a mobile station, received channel state values are sequentially stored. Then, the differences between all adjacent channel state values are calculated and summed. The sum is compared with a predetermined threshold. If the sum is greater than or equal to the predetermined threshold, the transmission format of the packet data is determined as the first format. If the sum is less than the predetermined threshold, the transmission format of the packet data is determined as the second format.

9. An apparatus for determining the transmission format of packet data between a first format and a second format longer than the first format based on channel state values received from a mobile station, comprising:
-
a calculation portion for determining the change history of received channel state values representing a change in mobile station-requested transmission rate as received from the mobile station as a numerical value; and a controller for determining the transmission format of the packet data as the first format if the output of the calculation portion is greater than or equal to a predetermined threshold and determining the transmission format of the packet data as the second format if the output of the calculation portion is less than the predetermined threshold. - View Dependent Claims (10, 11, 12, 13, 14, 15)
