DCFirst Claim
1. A channel coding and multiplexing apparatus for a CDMA communication system, in which data frames that have different transmission time intervals (TTIs) are received in parallel via a plurality of transport channels and multiplexed to a serial data frame, the apparatus comprising:
- a number of radio frame matchers, the number of radio frame matchers being at least equal to the number of the transport channels, each radio frame matcher having a radio frame segmenter for receiving the data frames and segmenting the data frames into radio frames; and
a multiplexer for multiplexing the radio frames to the serial data frame,wherein each radio frame segmenter determines the bit number of a radio frame according to the size of the data frames received by the corresponding frame matcher and the TTI of a radio frame and divides the data frames by the bit number of the radio frame.

Abstract
A channel coding and multiplexing apparatus and method in a CDMA communication system is disclosed. In the channel coding and multiplexing apparatus, each of a number of radio frame matchers (equal in number or greater than the number of transport channels) has a radio frame segmenter and segments each of transport channel frames that may have different transmission time intervals to radio frames. A multiplexer multiplexes the radio frames to form a serial data frame.
