    摘要: An apparatus and a method for interference cancellation in a Multiple Input Multiple Output (MIMO) wireless communication system. The method for interference cancellation includes equalizing first reception signals received through two or more reception antennas to estimate transmission signals transmitted through two or more transmission antennas, generating two or more second reception signals in which a mutual interference between the transmission signals is removed from the first reception signals by using the estimated transmission signals, independently equalizing the generated two or more second reception signals, and combining the independently equalized two or more second reception signals to estimate a transmission signal in which an interference is removed.

    摘要: A method for receiving a signal using an equalizer receiver in a mobile communication system includes matched-filtering a signal received via an antenna. The method also includes generating different phase information for a serving cell and one or more other cells. The method further includes generating Pseudo-random Noise (PN) codes for the cells based on the phase information; estimating channel estimation values for the cells using the PN codes and the filtered signal; modeling random sequences similar in statistical property to signals transmitted from the cells using the channel estimation values, and generating a filter coefficient using the modeled random sequences; and equalizing the filtered signal using the filter coefficient. By doing so, the receiver's channel estimation performance and equalizer adaptation performance may be maximized.

    摘要: A mobile terminal includes a channel estimation module that is maintained in an active state. A controller determines an activation time point of an equalizer weight calculation module for calculating a tap coefficient. The activation time point is earlier than an activation time point of a main equalizer module, and activates the equalizer weight calculation module at the activation time point so as to calculate the tap coefficient. When the equalizer weight calculation module's operation is completed, the controller activates the main equalizer module, detects a mobile terminal ID, activates an interference cancellation module, and controls the main equalizer module to provide a data signal demodulator with the data signal compensated for by the tap coefficient. A demodulator demodulates the compensated data signal.

    摘要: An apparatus and a method effectively adds and deletes a relay link in a communication system that includes a multiple relay system. The apparatus and method include determining by a relay mode controller whether to add or delete the relay link with consideration of at least one of a movement velocity of User Equipment (UE), a signal intensity of a Node-B and at least one relay station, and a channel state value of the UE. When addition or deletion of the relay link is determined, a message requesting addition of the relay link or a message informing deletion of the relay link is transmitted by a signaling processor to a relay station corresponding to the relay link whose addition or deletion has been determined.

    摘要: A method of uplink transmission scheduling for a network including at least one radio network controller (RNC), at least one user equipment (UE), and a plurality of Node Bs, with the steps of determining a parameter to be used in uplink transmission scheduling by considering uplink noise rise of the plurality of Node Bs, and performing the uplink transmission scheduling in accordance with the determined parameter. By determining the parameter upon considering the effects of the transmit power or transmit rate for a particular UE in soft handover with a scheduling Node B on the uplink noise rise of other neighboring Node Bs that are in soft handover but not scheduled with that particular UE, uplink transmission scheduling performance degradation can be prevented and more effective control of uplink noise rise at each Node B is possible.

    摘要: A method of informing a terminal of uplink synchronization acquisition in a mobile communication system by using downlink transmit power control (TPC) bits. The base station modifies and transmits power control bit patterns according to certain ‘N’ values defined as a pattern 01 count, and the terminal detects an indicator that informs uplink synchronization acquisition by the modified power control bit pattern. The terminal also maintains the transmit power of the synchronization acquisition timing by increasing the transmit power by an amount equal to the decrease caused by receiving the power control bits for detecting uplink synchronization acquisition.
