摘要： There is provided a reverse data rate determining method in a mobile communication system for high data rate transmission such as an HDR system. An AN within a cell calculates the total load of a reverse link by measuring the total energy of the reverse link from ATs within the cell. The AN calculates the share of each AT in the total reverse link load. If the load share of an AT is greater than a threshold predetermined individually for the AT, the AN determines that the AT should reduce its data rate.

摘要： Disclosed is a handover controlling method in an RNC connected to a first Node B and a second Node B in a mobile communication system where a USTS service occurs between the first Node B and a UE within a cell of the first Node B and the UE hands over when the UE is located in a handover area across the cell areas of the first Node B and the second Node B adjacent to the first Node B. The method comprises determining whether the handover for the UE is possible or not; transmitting handover information to the second Node B if the handover is possible; and transmitting a command to the UE through the first Node B, requesting the UE to hand over to the second Node B if the UE receives a response message indicating that the handover is possible from the second Node B.

摘要： A method for generating a preamble sequence in an OFDM (Orthogonal Frequency Division Multiplexing) communication system that uses A sub-carriers in a frequency domain and uses N Tx (Transmission) antennas, includes the steps of: generating N sequences, each having a length of ‘B/N’, by dividing B sub-carriers from among the A sub-carriers by the ‘N’ indicative of the number of the Tx antennas; and mapping, for each of the N sequences, individual components of the sequence to the B/N sub-carriers from among the A sub-carriers on a one by one basis in order to assign the components of the sequence to the B/N sub-carriers, and assigning null data to remaining sub-carriers other than the B/N sub-carriers from among the A-sub-carriers, such that a preamble sequence of a corresponding Tx antenna is generated.

摘要： There is provided a data communication apparatus and method in a multi-carrier CDMA communication system. A transmitting device determines whether a supplemental channel is transmitted. If the supplemental channel is transmitted, the transmitting device assigns the supplemental channel to each of all FAs having different carrier frequency bands and the other channels including a fundamental channel, a dedicated control channel, and a common control channel to one of the FAs. A receiving device determines whether the supplemental channel exists in input channel signals. If the supplemental channel exists, the receiving device despreads supplemental channel signals in each of the FAs, connects the despread supplemental channel signals to a supplemental channel decoder, despreads the other channels in one of the FAs, and connects the other channel signals to corresponding channel decoders.
