    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: A method and apparatus for transmitting Channel State Information Reference Symbol (CSI-RS) and data with partial muting of the CSI-RS are proposed. The method includes determining a CSI-RS pattern to be used among CSI-RS pattern candidates, determining a muting pattern for muting some resource elements constituting CSI-RS pattern candidates except for the determined CSI-RS pattern, mapping data symbols and CSI-RS to resource elements in a resource grid with rate patching in consideration of the CSI-RS pattern and muting pattern, and transmitting the data symbols and CSI-RS to a terminal.

    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.
