    摘要: A method of transmitting data in a wireless communication system includes preparing a frame including a unicast subframe for unicast data and an MBS (Multicast and Broadcast Service) subframe for MBS data; and transmitting the unicast data and the MBS data via the frame, wherein the MBS subframe includes an idle time during which data is not carried, and the idle time is arranged to be at the temporally latest position in the MBS subframe. An MBS frame structure for using an appropriate CP with respect to MBS signals transmitted from multi-cell is provided, so an unnecessary idle time can be reduced, and thus, the efficiency of limited radio resources can be improved.

    摘要: A method and apparatus for transmitting data having time diversity and data having time-frequency diversity, and a pattern generating method for the same are disclosed. The apparatus enables Tx data to have time diversity or time frequency diversity using a predetermined pattern multiplied by Tx data of a time domain or Tx data of time and frequency domains. The apparatus makes a cyclic delay diversity (CDD) scheme to have the diversity of time and frequency domains, and may acquire an additional diversity gain by a combination of the above-mentioned methods.
