Title:
POWER CONTROL REALIZING METHOD FOR CONTROL CHANNEL AND DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/101400
Kind Code:
A1
Abstract:
A power control method realizing for control channel includes: measuring the interval between the control channel transmission at this time and the control channel transmission at last time; comparing the measured interval with the threshold interval which has been pre-established, if the interval is greater than or equal to the pre-established threshold interval, carrying out control channel transmission at this time using initiate transmit power or controlling the control channel transmission at this time using open-loop power control mode; otherwise, the control channel transmission at this time using closed loop power control mode. Specially, when the control channel is uplink control channel, that is to be determined whether adding in the compensate of loss variations in the link base on closed-loop power control according to related order and to solve the problem that exists in prior art when control channel transmission is discontinuous, power control can not be carried out effectually. A power control realizing device for control channel is also provided corresponding.
