    摘要: A transmission scheme newly adds a Demodulation Reference Signal (DM-RS) to estimate a channel response for demodulation. When a transmission scheme based on Long Term Evolution Common Reference Signal (LTE CRS) is set in a user, a corresponding user cannot receive data in a Multimedia Broadcast Multicast Service Single Frequency Network (MBSFN) sub-frame. To solve this problem, the present scheme separates and sets a transmission mode for sub-frame and a transmission mode for MBSFN.

    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.
