MOBILE COMMUNICATION METHOD, RADIO BASE STATION AND MOBILE STATION

Title:

MOBILE COMMUNICATION METHOD, RADIO BASE STATION AND MOBILE STATION

Document Type and Number:

WIPO Patent Application WO/2013/073479

Kind Code:

A1

Abstract:

From among multiple duplexers (D1/D2), the invention appropriately selects the duplexer (D1/D2) that should be used. The mobile communication method according to the invention is a mobile communication method in a mobile communication system (1) operated in a band (F1), said mobile communication method comprising: a process (A) in which a radio base station (eNB) within the mobile communication system (1) sends, to a mobile station (UE), information pertaining to a system (X) being operated on a band (2) adjacent to the band (F1), and information pertaining to a system (Y) being operated on a band (3) adjacent to the band (1); and a process (B) in which on the basis of the information pertaining to the system (X) and the information pertaining to the system (Y), the mobile station (UE) selects the duplexer (D1 or D2) that should be used from among multiple duplexers (D1/D2).
