Abstract:
1. A base station (BS), comprising: a region information generator to determine additional assignment of a second region in a frequency band different from a first region in the frequency band, a component carrier (CC) of the first region having a bandwidth narrower than a maximum assignable bandwidth of the CC, and to generate information associated with the second region; a mapping controller to generate a reference signal to be used for channel estimation in the first region and the second region, and to control the reference signal to be assigned to a frequency band including the first region and the second region; a signal generator to generate a wireless signal comprising the information associated with the second region and the reference signal assigned by the mapping controller; and a transmitter to transmit the generated wireless signal, wherein the BS allocates resources to the first region and the second region so as to perform transmission and reception of data with a user equipment (UE), wherein the information associated with the second region is included in a control region or control information of the CC of the first region as an indicator.
