    Abstract: The present disclosure relates 5G or pre-5G communication systems for supporting higher data transmission rate than those by LTE or other post-4G communication systems. According to the present disclosure, a method for operating a beamformed reference signal by a base station and terminal in a communication system, and the terminal, are provided. The method includes transmitting, to a terminal, control information indicating whether a first codebook is used for generating feedback information on a downlink reference signal. The first codebook is used if generating feedback information on the beamformed reference signal and is generated based on a number of antenna ports and a number of ranks.

    Abstract: Provided is a method and apparatus for transmitting and receiving a Broadcast Channel (BCH) in a cellular communication system. The method for transmitting a BCH in a cellular communication system includes repeating symbols comprising information about the BCH, code-covering the repeated symbols with codes selected from a previously given code set, subcarrier-mapping the code-covered symbols, and transmitting the subcarrier-mapped symbols in one frame by using different beams corresponding to the selected codes. The codes are selected based on a number of repetitions, a cell identifier, and a beam index.

    Abstract: The present invention relates to a method for operating, by a base station, multiple modulation schemes in a wireless communication system, the method comprising the steps of: calculating the number of terminals, among the terminals in a cell managed by the base station, of which a channel state is included in a state that is lower than a preset state; reporting information related to the calculated number of terminals to an upstream entity of the base station; receiving information about a band, assigned by the upstream entity, for a hybrid frequency shift keying (FSK) and quadrature amplitude modulation (QAM) (FQAM) scheme on the basis of a QAM scheme and a FSK scheme; and transmitting downwardly the information about the band for the FQAM scheme to the terminals of which a channel state is included in a state that is lower than the preset state. Other modified embodiments on the basis of the technical concept of the present invention are also possible.
