    摘要： A modulation mapper (1003) selects respective data blocks (DBs) hierarchically and sequentially in descending order of a transmission power ratio; locates, from a resource element group, unused REs to which modulation symbols can be allocated; and decides the allocation of modulation symbols in the REs. A channel resource element mapper (1004) performs the mapping of modulation symbols of the respective DBs to the REs on the basis for the decided allocation. A complex-value transmission signal is generated from the group of REs.

    摘要： The present invention relates to a handover method in CDMA mobile communication. A base station and a mobile station of the same establishes synchronization after the handover by correcting a discrepancy of a frame number on the base station side to reduce the processing load of the mobile station. Further, at the same time, optimumly performing a phase correction of the frame. In particular, a mobile station MS measures a time difference □ between a frame timing in an upstream traffic channel and a frame timing in a perch channel from a second base station BS2. Further, the second base station transmits the time difference □ to a base station in communication BS1. The base station BS1 sends the time difference □ and a frame number FN1 in the upstream traffic channel in communication to the base station BS2. The base station BS2 corrects the phase of the spread code at the reception of the upstream traffic channel based on the received time difference □ of the frame timing and the notified frame number FN1.
