Abstract

The invention provides a mobile station, a transmitting method and a mobile communication system. The mobile station includes: a mapping unit which maps pilot signals to sub carriers selected by dispersion with a certain space in a part of frequency band of at least a part of the system frequency band including a plurality of sub carriers; and a transmitting unit which transmits the mapped pilot signals in the mapping unit. The mapping unit sets a part of the frequency band according to the frequency and the band width designated by the base station device; and the frequency band and the band width are orthogonal to the pilot signals transmitted from other mobile stations in the frequency axis.

Description

[0001] This application is a divisional application of the following invention patent application: application number: 200680017997.5, application date: 2006.03.23, invention name: sending device, receiving device, mobile communication system and sending control method. technical field [0002] The invention relates to a sending device, a receiving device, a mobile communication system and a sending control method. Background technique [0003] The development of the fourth-generation mobile communication system (4G), which is the next-generation mobile communication system of IMT-2000 (International Mobile Telecommunications 2000; International Mobile Telecommunication 2000), is advancing. In the fourth-generation mobile communication system, it is possible to flexibly support multi-cell environments such as cellular systems to isolated cell environments such as hotspot areas and indoors, and it is expected to increase frequency utilization efficiency in both cell environmen...
