A method of transmitting a data packet based on a transport format combination set (TFCS) using a hybrid automatic repeat request (HARQ) is disclosed. In the method, a user equipment (UE) receives a TFCS from a base station (BS) to select a transport format combination (TFC) for retransmitting a data packet and selects from the TFCS a TFC which corresponds to a maximum transmission power by which the data packet is retransmitted. Thereafter, the UE retransmits the data packet using the TFC of an initial transmission and a transmission power that corresponds to the TFC with the maximum transmission power of the TFCS.

Method of controlling transmit power for retransmission packet in uplink dedicated channel

A method of encoding and transmitting at least one short length data in a wireless communication system is provided. More specifically, a user equipment (UE) attaches at least one error detection code to the at least one short length data. Thereafter, the UE encodes for error correction the short length data and the attached error detection code using at least one block encoder. Here the short length data and the attached error detection code are independently encoded. Lastly, the UE transmits the encoded short length data and the encoded error detection code.

A power control method in a mobile communication system quickly reduces DPCCH power when ending the transmission of a HS-DPCCH signal down to a level requested by the transmission of a current DPCCH signal, thereby enabling effective control of uplink DPCCH power of a terminal and to significantly decrease uplink interference in the overall mobile communication system.

In a mobile communication system including SRNC and DRNC for controlling a plurality of base station, and mobile stations, a method for controlling power of TFCI field for DSCH if DSCH-associated DCH exists in a soft handover situation includes determining whether a base station which transmits DSCH is a primary base station or not, number of base stations that transmits TFCI, where the TFCIis information on the DSCH, setting a power offset according to a result of the determination, and transmitting the TFCIusing the set power offset.

An orthogonal spread code for a mobile communication system is provided which increases an interference free window (IFW) interval as well as the element number of the orthogonal code set. A large synchronization (LS) code is generated by using an initial 2&#xd7;2 matrix to generate magnified first and second square matrices. A third square matrix is then generated based on the first and second square matrices, and a code sequence is generated from the rows or columns of the third square matrix. In this manner, the inversely proportional relationship between the element number of the orthogonal code set and the IFW interval may be established, and used to avoid channel prediction errors and reduce power imbalance.
