| 1. A method for selecting transport formats corresponding to transport channels in a wideband code division multiple access
mobile communication system which includes a radio link control layer entity and a medium access control layer entity, the
radio link control layer entity converting a service data unit delivered from an upper layer into a protocol data unit and
transmitting the protocol data unit to the medium access control layer entity through a predetermined logical channel from
among a plurality of logical channels, the medium access control layer entity receiving the protocol data unit and converting
the protocol data unit into a transport block and transferring the transport block to a physical layer entity through a predetermined
transport channel from among a plurality of transport channels, the method comprising the steps of:
i) sorting logical channels according to priorities, the logical channels existing between the radio link control layer entity
and the medium access control layer entity;
ii) sorting transport format indicators according to the number of transport blocks for each corresponding transport format;
and
iii) selecting, according to a sequence of the sorted transport format indicators, transport formats supporting transport
blocks of a transport format indicator, a number of which is less than or equal to a number of data blocks to be transferred
through a logical channel according to each priority, wherein a transport format supporting the number of transport blocks
which is less than the number of data blocks is selected when a transport format supporting the number of transport blocks
equal to the number data blocks is unavailable.
