| 1. A method of setting a transport format combination (TFC) in a broadband code division multiple access (CDMA) communication
system, the method comprising:
a) transmitting from a radio resource control (RRC) layer both transport format set (TFS) information and transport format
combination set (TFCS) information during a channel initialization for data transmission among respective layers of the broadband
CDMA communication system;
b) selecting at a medium access control (MAC) layer an initial TFC for preferentially allocating a maximum packet data unit
(PDU) value to a transmission channel on which a logic channel having a relatively high priority among a plurality of transmission
channels has been mapped, wherein said allocation is initially achieved by analyzing the received TFS information and the
TFCS information;
c) transmitting an initial PDU value from the MAC layer to a radio link control (RLC) layer including respective logic channels
by allocating the initial PDU value according to the initial TFC to the respective logic channels before receiving buffer
occupancy information from the radio link control (RLC) layer; and
d) transmitting at the radio link control (RLC) layer initial transmission data along with buffer occupancy information of
a transmission buffer to the MAC layer based on the received initial PDU value.
