UL HS−DPCCHを開放して品質情報の送信を停止しているが、送信電力を小さくすることで品質情報の送信の停止を実現してもよい。 Although open the UL HS-DPCCH is stopped transmission of the quality information may be implemented to stop transmission of the quality information by reducing the transmission power. 【0058】次に、本発明の第6の実施例を説明する。 Next, a description will be given of a sixth embodiment of the present invention.
本実施例では、基地局は品質情報を送信させるための閾値を移動局に制御情報として送信する。 In this embodiment, the base station transmits the control information to the mobile station the threshold value for causing the transmission quality information. 移動局は自身の品質情報を測定し、受信品質が閾値と同じか上回る場合、品質情報を報告する。 The mobile station measures the quality information of its own, when the reception quality is above or equal to the threshold value, reporting the quality information. その際、品質情報と同時に、 At that time, quality information at the same time,
Feedback Indicatorも送信する。 Feedback Indicator is also transmitted. 【0059】本実施例では、基地局との間でチャネル設定をしてから所定のタイミングで、移動局が品質情報を送信し、最後のパケットデータを受信した後、移動局が品質情報の送信を停止するので、移動局のバッテリー動作時間が向上する。 [0059] In this embodiment, at a predetermined timing after the channel set up between the base station, the mobile station transmits the quality information, after receiving the last packet data transmission the mobile station is quality information the so to stop, to improve battery operating time of the mobile station. 更に、品質情報の送信を停止する場合、上り品質制御用チャネルを開放するので、多数の移動局の中で一部の移動局だけがUL HS−DPCCH Further, when stopping the transmission of the quality information, since opening the uplink quality control channel, only a portion of the mobile station in a large number of mobile stations UL HS-DPCCH

基地局が確実に品質情報を受信することができる。 The base station can reliably receive quality information. 更に、移動局の受信品質が閾値と同じか、上回る場合に品質情報を報告するので、誤り率の低い、高速伝送パケットサービスを実施することができる。 Furthermore, same as the reception quality of the mobile station is the threshold, since the report quality information if exceeded, can be implemented with low error rates, the high-speed transmission packet service. 【0060】図21、図22は本実施例の動作を示すフローチャートである。 [0060] Figure 21, Figure 22 is a flowchart showing the operation of this embodiment. 図21は基地局の動作を示すフローチャートであり、基地局において、移動局が品質情報を送信するための閾値を設定する処理動作を実現するものである。 Figure 21 is a flow chart showing the operation of the base station, the base station, the mobile station realizes the process operation for setting a threshold value for sending quality information. 図22は移動局の動作を示すフローチャートであり、基地局から受信する閾値を基に、受信品質が閾値を上回るか等しい場合に、品質情報を基地局に送信する移動局の処理動作を実現するものである。 Figure 22 is a flow chart showing the operation of the mobile station, based on the threshold value received from the base station, if the reception quality is equal to or exceeds the threshold value, implementing the processing operation of the mobile station transmitting the quality information to the base station it is intended. 【0061】図21を参照すると、基地局は受信品質の閾値Pと、閾値を調整するオフセットΔPと、移動局数の閾値Nを初期値として設定し、各移動局に送信する(S201)。 [0061] Referring to FIG. 21, the base station sets the threshold value P of the reception quality, an offset ΔP to adjust the threshold value, the threshold value N of number of mobile stations as an initial value, and transmits to each mobile station (S201). 次に、各移動局から品質情報を受信し(S202)、受信品質を報告した移動局がNを超えたか判定する(S203)。 Then, receiving the quality information from the mobile station (S202), and determines whether the mobile station that reported the reception quality exceeds N (S203). 報告した移動局数がNを超えれば、受信品質がN番目に良い移動局の品質情報を新たに閾値Pとして設定し、報告移動局の数がNとなるように、閾値Pを増加して各移動局に送信する(S20 If the number of the reported mobile station exceeds the N, setting the quality information of the reception quality is good N-th mobile station as a new threshold value P, so that the number of reported mobile station is N, and increasing the threshold value P to send to each mobile station (S20

P−ΔPを新たにPとして設定し、各移動局に送信する(S205)。 Set P-[Delta] P as a new P, and transmitted to each mobile station (S205). 【0062】こうすることにより、品質情報を基地局へ報告する移動局の数が所定値Nに等しくなるように制御されるので、多数の移動局のうち、受信品質の良い一部の移動局だけがUL HS−DPCCHを設定するので、上り干渉波電力の低減が可能となり、また上り無線回線容量を増やすことができるのである。 [0062] By doing so, since the number of mobile stations to report the quality information to the base station is controlled to be equal to a predetermined value N, a number of mobile stations, some good reception quality mobile station since only sets the UL HS-DPCCH, it is possible to reduce the uplink interference power, also it is possible to increase the uplink radio channel capacity. 【0063】図22は第3の実施例の図12のフローチャートのS122の処理をS151,S152に変更したものになっている。 [0063] Figure 22 has become a modification of the process of S122 in the flowchart of FIG. 12 in the third embodiment in S151, S152. 即ち、移動局は基地局との間でチャネル設定を行った後、所定の時間が経過するのを待ってから(S121)、受信品質を測定し(S151)、 That is, after the mobile station performing the channel set up between the base station, wait for a predetermined time elapses (S121), measures the reception quality (S151),
受信品質が基地局から通知された閾値Pを上回るか等しいか判定し(S152)、上回るか等しければ、Feedba The reception quality is judged whether equal to or greater than the notification threshold P from the base station (S152), or equal than, Feedba
