A method for processing a control channel, comprising: determining an activated Beam Area, BA, of a control channel according to receiving power in a BA; allocating control channel resources according to a scheduling condition in a cell; and sending a control signal according to the activated BA of the control channel and an allocation condition of the control channel resources; characterized in that, wherein determining the activated BA of the control channel comprises: obtaining receiving power in respective BAs and converting the receiving power in respective BAs according to standard transmitting power and performing time-domain smoothing on the receiving power converted based on standard transmitting power in respective BAs; judging a proportional relation between smoothing receiving power in respective BAs and maximal smoothing receiving power, and when a ratio of smoothing power value in a BA to the maximal smoothing power of all the BAs is higher than or equal to a first activation threshold, determining that the BA is activated; or, obtaining receiving power in respective BAs and converting the receiving power in respective BAs according to standard transmitting power, performing time-domain smoothing on the receiving power converted based on standard transmitting power in respective BAs, and arranging obtained receiving power smoothing values in respective BAs in an ascending order, wherein a minimum smoothing value is arranged at a head; subtracting the smoothing value at the head from a sum of smoothing receiving power in respective BAs to obtain a difference, and subjecting the difference and a sum of receiving power smoothing values in respective BAs to division computation to obtain an activation ratio; judging whether the activation ratio is higher than or equal to a preset second activation threshold; and when the activation value is higher than or equal to the second activation threshold, deleting the smoothing value at the head; repeating the operation of obtaining the activation ratio till the obtained activation ratio is lower than the second activation threshold, and then determining that BAs corresponding to the smoothing value at the head and BAs corresponding to remaining smoothing values are activated BAs. determining an activated Beam Area, BA, of a control channel according to receiving power in a BA; allocating control channel resources according to a scheduling condition in a cell; and sending a control signal according to the activated BA of the control channel and an allocation condition of the control channel resources; characterized in that, obtaining receiving power in respective BAs and converting the receiving power in respective BAs according to standard transmitting power and performing time-domain smoothing on the receiving power converted based on standard transmitting power in respective BAs; judging a proportional relation between smoothing receiving power in respective BAs and maximal smoothing receiving power, and when a ratio of smoothing power value in a BA to the maximal smoothing power of all the BAs is higher than or equal to a first activation threshold, determining that the BA is activated; or, obtaining receiving power in respective BAs and converting the receiving power in respective BAs according to standard transmitting power, performing time-domain smoothing on the receiving power converted based on standard transmitting power in respective BAs, and arranging obtained receiving power smoothing values in respective BAs in an ascending order, wherein a minimum smoothing value is arranged at a head; subtracting the smoothing value at the head from a sum of smoothing receiving power in respective BAs to obtain a difference, and subjecting the difference and a sum of receiving power smoothing values in respective BAs to division computation to obtain an activation ratio; judging whether the activation ratio is higher than or equal to a preset second activation threshold; and when the activation value is higher than or equal to the second activation threshold, deleting the smoothing value at the head; repeating the operation of obtaining the activation ratio till the obtained activation ratio is lower than the second activation threshold, and then determining that BAs corresponding to the smoothing value at the head and BAs corresponding to remaining smoothing values are activated BAs.
