Abstract: A variable sub-carrier mapping method comprising steps of: applying different bit interleaving schemes to different transmissions of a hybrid automatic retransmission request(HARQ) process in side of transmitter; and in the side of the transmitter, modulating symbols onto sub-carriers for transmitting. Different transmissions in one HARQ process adopt different bit interleavers or different symbol-to-sub-carrier mapping methods so as to realize that the same bit of different transmissions in one HARQ process is transmitted via different sub-carriers. Therefore, the system achieves the frequency diversity gain and reduces the probability of failure of HARQ transmission caused by that some bits are always transmitted via the sub-carrier with the same deep fading. In this way, the average HARQ retransmission times can be reduced and the system throughput can be improved.

Abstract: The present invention supposes a situation in which an Enhanced Uplink Dedicated transport Channel (EUDCH) is used in a mobile communication system. The present invention proposes a method for increasing the maximum possible number of code channels for E-DPDCH by dynamically allocating OVSF codes allocated to DPDCH and HS-DPCCH supporting a high-speed downlink packet service, to a E-DPDCH every TTI. Therefore, a Node B can normally demodulate E-DPDCH/DPDCH/HS-DPCCH data, increasing a EUDCH data rate.

Abstract: Disclosed is a method for reporting channel state information between a mobile station and a base station to the base station by the mobile station in a mobile communication system. The method includes the steps of mapping the channel state information to a value stored in a channel state information table. The mapping is determined by a range of traffic-to-pilot ratio (TPR) values. The TPR values are determined according to an encoder packet site packet data rate relation. The mapping is then transmitted to the base station.

Abstract: A method is provided for a case where an allocation area of data indicated by control information overlaps a subsequent control information area occurring after the control information area is pre-configured by a higher layer signal or system information. A terminal may omit or partially perform a blind search for the subsequent control information area overlapping the data area. Additionally, a terminal may receive data based on an assumption that a data area has been mapped to the subsequent control information area, or a terminal may receive data based on an assumption that a data area has not been mapped to the subsequent control information area. Thus, the terminal may adaptively adjust a configuration area for a data area and prevent blind decoding to further reduce power consumption.
