Abstract
A control unit (102) in a radio base station (1A) receives a measurement W-CQI message from a radio terminal (2A) and acquires the usage rate of the PDCCH corresponding to the serving sector. Further, the control unit (102) in the radio base station (1A) multiplies the measurement W-CQI corresponding to the serving sector by the reciprocal of the usage rate of the PDCCH corresponding to the radio base station (1A), and thereby estimates the SINR of the PDCCH corresponding to the serving sector at the radio terminal (2A).
Claims6
A radio base station in a radio communication system having a downlink radio resource including a user data channel and a control channel, the radio base station comprising:
- a first acquisition unit configured to acquire information showing a reception quality of the user data channel received by the radio terminal in a predetermined cell or a predetermined sector;
- a second acquisition unit configured to acquire a value determined according to a usage rate of the control channel corresponding to a cell other than the predetermined cell or a sector other than the predetermined sector;
- and
- an estimation unit configured to estimate a reception quality of the control channel received by the radio terminal in the predetermined cell or the predetermined sector based on the information showing the communication quality of the user data channel acquired by the first acquisition unit and the value determined according to the usage rate of the control channel acquired by the second acquisition unit.
A communication control method for a radio base station in a radio communication system having a downlink radio resource including a user data channel and a control channel, the communication control method comprising the steps of:
- acquiring information showing a reception quality of the user data channel received by the radio terminal in a predetermined cell or a predetermined sector;
- acquiring a value determined according to an usage rate of the control channel corresponding to a cell other than the predetermined cell or a sector other than the predetermined sector;
- and
- estimating a reception quality of the control channel received by the radio terminal in the predetermined cell or the predetermined sector based on acquired information showing the communication quality of the user data channel and an acquired value determined according to the usage rate of the control channel.
