Title:
RADIO BASE STATION SYSTEM, RADIO BASE STATION CONTROL APPARATUS, NUMBER-OF-ACCOMMODATED-CELLS DECIDING PROGRAM AND NUMBER-OF-ACCOMMODATED-CELLS DECIDING METHOD
Document Type and Number:
WIPO Patent Application WO/2011/078249
Kind Code:
A1
Abstract:
A radio base station system (10) at least can set a cell (C1) having a first bandwidth (for example, 20 MHz) and a cell (C3) having a second bandwidth (for example, 10 MHz). A radio base station (100A, 100B) has a plurality of types of BB cards for which the combinations of numbers of accommodable cells are mutually different. Based on a ratio of a first number of accommodable cells in a case where only cells of 20 MHz are accommodated into a BB card to a second number of accommodable cells in a case where only cells of 10 MHz are accommodated into the BB card, the radio base station (100A, 100B) determines whether to perform the cell accommodation into the BB card.
