Method and apparatus for operating multi-band and multi-cell

摘要

Disclosed are a method and an apparatus for operating multi-band and multi-cell. An Enhanced Node B (eNB) transmits a synchronization channel and a broadcasting channel for narrow-band user equipments (UEs) through a first band narrower than a system band, the first band being located in a center band of the system band, and transmits a control channel for scheduling a data channel for a first narrow-band UE which is one of the narrow-band UEs through a second band equal to or wider than the first band, the second band not overlapping the first band within the system band. The first band is designed to be matched to a band where the synchronization channel and the broadcasting channel of a host cell using an entire system band are transmitted.

1. A method of operating multi-band and multi-cell, the method comprising:
transmitting a synchronization channel and a broadcasting channel for narrow-band User Equipments (UEs) through a first band narrower than a system band, the first band being located in a center band of the system band; transmitting a control channel for scheduling a data channel for a first narrow-band UE, which is one of the narrow-band UEs, through a second band equal to or wider than the first band, the second band not overlapping the first band within the system band; and establishing Radio Resource Control (RRC) connection with the first narrow-band UE which is one of the narrow-band UEs through the first band, and transmitting information on the second band and location information of a subframe where the control channel is transmitted to the first narrow-band UE through the RRC connection, wherein the first band is equal to a band where the synchronization channel and the broadcasting channel of a host cell using an entire system band are transmitted.
