Embodiment Construction

[0053] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings. Throughout the drawings, the same or corresponding elements are denoted by the same reference numerals, and redundant descriptions thereof will be omitted unless necessary.

[0054]

[0055] This illustrative embodiment shows the following example: the relay station 2 determines the donor cell from at least one candidate indicated by the donor cell list based on the first cell management information received from the base station 1 and the second cell management information managed by the relay station 2 . The first cell management information involves at least one candidate cell, and comes from base station 1 (or multiple base stations 1). In other words, the first cell management information relates to at least one candidate cell, and is managed or saved by the base station 1 . The first cell management information relates to a first ...

Abstract

A mobile communication system includes a base station (1) and a relay station (2). The relay station (2) acquires a donor cell list indicating at least one candidate cell that can be used for a backhaul link (BL1). The relay station (2) or the base station (1) determine a donor cell used for the backhaul link (BL1) from the donor cell list based on both first and second cell management information. The first cell management information relates to the at least one candidate cell and originates from the at least one base station (1). The second cell management information originates from the relay station (2).

Description

technical field [0001] The invention relates to a method of selecting a cell for connection between a relay station and a base station from a plurality of candidate cells of a mobile communication system comprising a base station and a relay station belonging to the base station. Background technique [0002] In LTE-Advanced (Long Term Evolution) of 3GPP (3rd Generation Partnership Project), introduction of a relay station (hereinafter referred to as "relay node (RN)") has been examined (see NPL 1 and 2). RN is used to increase the communication rate of a mobile station (hereinafter referred to as "User Equipment (UE)") located at the cell edge and / or to increase the cell area of ​​a base station (hereinafter referred to as "evolved NodeB (eNB)") one of the technologies. Details of the RN architecture examined in 3GPP are shown in NPL2. [0003] An outline of a mobile communication system based on the RN architecture disclosed in NPL2 is explained below. figure 1 An examp...
