Abstract

Immediately before transmitting a packet signal, a packet transmission base station (BS1) increases a target SIR of UL DPCH (S12), increases the TPC transmission power transmitted by the DL DPCH (S13), increases a power balancing reference power, and increases a DL DPCH transmission power (S14). In a mobile station (MS3), during packet reception, only a packet transmission base station (1) controls the UL DPCH transmission power (S15). This improves the reception quality at the base station (1) of HS-DPCCH including ACK / NACK and reduces the error ratio of the ACK / NACK signal.

Description

[0001] This application is a divisional application based on the invention with application number 03807558.X and application date of April 3, 2003, entitled "cellular system, base station and mobile station, and communication control method". technical field

[0002] The present invention relates to a cellular system, a base station and a mobile station, and a communication control method. Background technique

[0003] Conventionally, various systems have been proposed for such a cellular system. Recently, as one of such cellular systems, a high-speed downlink packet access (HSDPA: High-Speed ​​Downlink Packet Access) cellular system has been proposed by 3GPP (Third Generation Partnership Project).

[0004] Hereinafter, a cellular system for performing packet communication will be described by taking the aforementioned cellular system of the HSDPA scheme as an example, but the present invention is not limited to HSDPA.

[0005] In the HSDPA method, high-speed data is trans...
