    摘要： Methods and apparatus are provided for transmitting and receiving reference signals through distributed antennas deployed within a service area of a base station in a mobile communication system. First control information, including at least two scrambling factor combinations, is received at a terminal from the base station. Second control information, indicating one of the at least two scrambling factor combinations, is received at the terminal from the base station. The one of the at least two scrambling factor combinations is selected based on the second control information. An initial value of a demodulation reference signal sequence is calculated using the selected scrambling factor combination. The demodulation reference signal sequence is received using the initial value.

    摘要： An LTE-A system and power control method for controlling cell interference based on codeword-specific transmission power adjustment with a transmission power control offset parameter. The method includes transmitting a parameter KS signaled by a higher layer and codeword-specific power control parameters from a base station to a terminal; calculating gains at the terminal, using the codeword-specific power control parameters and the parameter KS; calculating, at the terminal, codeword-specific transmit powers according to the gains; and transmitting, from the terminal to the base station, at least two codewords at the codeword-specific transmit powers.

    摘要： The objective of the present invention is to control the HARQ process for two codewords assigned to each UE in downlink of the LTE-A system efficiently. In the proposed method, particularly when one of the two codewords is decoded successfully but the other is not in the HARQ process, the UE can be scheduled for both the retransmission and initial transmission by means of the control signal of PDCCH or ACK/NACK information of PHICHs. The proposed method is capable of reducing resource amount necessary for the control signal transmission without increasing the PDCCH decoding complexity of the UE.
