APPARATUS AND METHOD FOR TRANSMITTING SIGNALS IN DYNAMIC SPECTRUM SHARING SYSTEM

원문 (중국어)

A method performed by a base station that supports dynamic spectrum sharing (DSS) for long term evolution (LTE) and new radio (NR) is provided. The method includes the processes of mapping first downlink data associated with NR onto resource elements (REs) in the data region of a subframe, differentiating second partial data from first partial data, the first partial data having been mapped onto first REs based on a cell-specific reference signal (CRS) pattern associated with LTE, among the REs, and the second partial data having been mapped onto second REs that are different from the first REs, transmitting the second partial data in the second REs, after establishing a radio resource control (RRC) connection with a terminal associated with NR, mapping second downlink data onto fourth REs, which exclude third REs based on a CRS pattern associated with LTE among REs in the data region of a different subframe, and transmitting the second downlink data in the fourth REs.
