Method and apparatus for configuring transport format combination set in a mobile communication system

A method of configuring a transport format combination set (TFCS) in a mobile communication system, the method comprising:

• generating transport channel configuration information related to establishment of transport channels;
• generating TFCS configuration information comprising a transport combination format calculated transport format combination (TFC-CTFC) auto mapping indicator indicating one-to-one mapping between CTFCs and TFCs, the CTFCs being all possible combinations of transport formats (TFs) of different transport channels;
• inserting the generated transport channel configuration information and the TFCS configuration information into a transport channel establishment message;
• and
• transmitting the transport channel establishment message to a user equipment (UE).

An apparatus for configuring a transport format combination set (TFCS) in a mobile communication system, the apparatus comprising:

• a transmitter and receiver for receiving transport channel configuration information and TFCS configuration information in a transport channel establishment message from a radio network controller (RNC), and transmitting a response message to the RNC, when transport channels are completely configured according to the transport channel establishment message;
• a transport channel controller for establishing the transport channels based on the received transport channel configuration information;
• a calculated transport format combination (CTFC) calculator for calculating a CTFC set comprising all possible combinations of transport formats (TFs) of different transport channels according to the received transport channel configuration information;
• and
• a transport combination format -calculated transport format combination (TFC)-CTFC mapper for determining whether the TFCS configuration information comprises a TFC-CTFC auto mapping indicator, mapping CTFCs comprised in the CTFC set to TFCs in a one-to-one correspondence, if the received TFCS configuration information comprises the TFC-CTFC auto mapping indicator, and providing information regarding the mapping to the transport channel controller.

An apparatus for configuring a transport format combination set (TFCS) in a mobile communication system, the apparatus comprising:

• a transport channel configuration information generator for generating transport channel configuration information related to establishment of transport channels;
• a TFCS configuration information generator for generating TFCS configuration information comprising a TFC-CTFC auto mapping indicator indicating one-to-one mapping between calculated transport format combinations (CTFCs) and transport format combination (TFCs), the CTFCs being all possible combinations of transport formats (TFs) of different transport channels;
• a message combiner for inserting the generated transport channel configuration information and the generated TFCS configuration information into a transport channel establishment message;
• and
• a transmitter and receiver for transmitting the transport channel establishment message to a user equipment (UE).
