A repair method for missing detection of a control channel, comprising: sending, by a base station, a physical downlink control channel, PDCCH, to a user equipment, UE, to indicate usage conditions of uplink and downlink transmission resources; receiving (31, 41), by the base station, a physical uplink shared channel, PUSCH, sent by the UE; detecting, by the base station, whether the UE misses detecting the PDCCH; and performing, by the base station, repair by using a repair policy after it is detected that the UE misses detecting the PDCCH; wherein the repair policy comprises the following: re-delivering an uplink grant indication to the UE to instruct the UE to adopt an uplink adaptive hybrid automatic repeat request, HARQ, to retransmit data; counting a detected missing detection state of the PDCCH in block error ratio statistic of the PDCCH; for a first transmission time interval, TTI, wherein the first TTI is a transmission time interval when it is determined that the UE misses detecting the PDCCH, executing the following: determining a cyclic redundancy check, CRC, verification error in the first TTI and not counting the determined CRC verification error in not acknowledge, NACK, statistics; discarding a channel quality indicator, CQI, received in the first TTI and not using the CQI to determine downlink channel quality. sending, by a base station, a physical downlink control channel, PDCCH, to a user equipment, UE, to indicate usage conditions of uplink and downlink transmission resources; receiving (31, 41), by the base station, a physical uplink shared channel, PUSCH, sent by the UE; detecting, by the base station, whether the UE misses detecting the PDCCH; and performing, by the base station, repair by using a repair policy after it is detected that the UE misses detecting the PDCCH; wherein the repair policy comprises the following: re-delivering an uplink grant indication to the UE to instruct the UE to adopt an uplink adaptive hybrid automatic repeat request, HARQ, to retransmit data; counting a detected missing detection state of the PDCCH in block error ratio statistic of the PDCCH; for a first transmission time interval, TTI, wherein the first TTI is a transmission time interval when it is determined that the UE misses detecting the PDCCH, executing the following: determining a cyclic redundancy check, CRC, verification error in the first TTI and not counting the determined CRC verification error in not acknowledge, NACK, statistics; discarding a channel quality indicator, CQI, received in the first TTI and not using the CQI to determine downlink channel quality. re-delivering an uplink grant indication to the UE to instruct the UE to adopt an uplink adaptive hybrid automatic repeat request, HARQ, to retransmit data; counting a detected missing detection state of the PDCCH in block error ratio statistic of the PDCCH; for a first transmission time interval, TTI, wherein the first TTI is a transmission time interval when it is determined that the UE misses detecting the PDCCH, executing the following: determining a cyclic redundancy check, CRC, verification error in the first TTI and not counting the determined CRC verification error in not acknowledge, NACK, statistics; discarding a channel quality indicator, CQI, received in the first TTI and not using the CQI to determine downlink channel quality. determining a cyclic redundancy check, CRC, verification error in the first TTI and not counting the determined CRC verification error in not acknowledge, NACK, statistics; discarding a channel quality indicator, CQI, received in the first TTI and not using the CQI to determine downlink channel quality.
