Embodiment Construction

[0088] Hereinafter, preferred embodiments of a base station apparatus, a mobile station apparatus, and a radio communication system thereof according to the present invention will be described with reference to the drawings.

[0089] Hereinafter, terms used in this specification are defined.

[0090] DCFC (Downlink CQI Feedback Cycle) indicates an interval at which the mobile station apparatus measures the DPiCH, calculates the downlink CQI, and transmits the downlink CQI to the base station apparatus.

[0091] UAP (Uplink Active Period) indicates an interval during which the mobile station apparatus can transmit control information or user data using the uplink (or an interval during which the base station apparatus can perform uplink scheduling for the mobile station apparatus). The downlink CQI is sent at the beginning of the UAP.

[0092] DAP (Downlink Active Period) indicates the interval at which the mobile station device can receive control information or user data fro...

Abstract

With communication service considered, it is an object to provide a communication system in which power consumption of a mobile station device is suppressed. This mobile communication system includes a base station device and a mobile station device, wherein the base station device includes a scheduling portion that carries out scheduling to determine a downlink CQI effective period scheduled by using the downlink CQI as a downlink effective period, start the downlink effective period after a lapse of a given period from downlink CQI transmission timing, and allow the mobile station device to transmit control information and user data only during the downlink effective period.

Description

technical field [0001] The present invention relates to a wireless communication system, a base station device and a mobile station device, in particular to the EUTRA technology in a mobile communication system, which has information packet data based on an adaptive modulation and demodulation / error correction method based on adaptive wireless link control communication method. Background technique [0002] In 3GPP (3rd Generation Partnership Project), the W-CDMA method is standardized as the third generation cellular mobile communication method, and services are started sequentially. In addition, HSDPA (High Speed ​​Downlink Packet Access), which further increases the communication speed, was also standardized and started to serve. [0003] In addition, in 3GPP, the evolution of third-generation radio access (Evolved Universal Terrestria Radio Access, hereinafter referred to as EUTRA) is studied. [0004] An OFDM (Orthogonal Frequency Division Multiplexing) scheme is prop...
