The embodiment of the invention aims at the characteristic of starting carrier aggregation and the number of downlink cells which can be monitored
In a scenario that the number of candidate PDCCHs is greater than 4, when the subcarrier interval μ corresponding to the th cell is different from the subcarrier interval j corresponding to the second cell, it is determined that the maximum number of candidate PDCCHs monitored in each time slot is th number, and the maximum number of non-overlapping CCEs monitored in each time slot is second number in the th cell, so that the maximum number of candidate PDCCHs to be monitored and the maximum number of non-overlapping CCEs can be determined, and complexity of monitoring PDCCHs by the UE is reduced.

In the specific implementation, because the existing implementation of cross-carrier scheduling for different subcarrier intervals makes it impossible for the UE to acquire the maximum number of PDCCH candidates (PDCCH candidates) to be monitored and the maximum number of non-overlapping CCEs, which results in high complexity of monitoring the PDCCH by the UE, the embodiment of the present invention provides the maximum number of PDCCH candidates and the maximum number of non-overlapping CCEs to be monitored in each time slot when the cross-carrier scheduling for different subcarrier intervals exceeds the maximum number of carriers required to be supported by the UE.
In the specific implementation, it is first determined that the base station configures the carrier aggregation function for the UE, that is, the UE starts the carrier aggregation characteristic, and the configured number of downlink cells that the UE can monitor is determined

the number of configured downlink cells which can be monitored.
In a specific implementation, the candidate PDCCHs may include candidate PDCCHs corresponding to different DCI sizes, or candidate PDCCHs corresponding to different Demodulation Reference Signal (DMRS) scrambling sequences, that is, PDCCHs corresponding to different DCI sizes are different candidate PDCCHs, and PDCCHs corresponding to different DMRS scrambling sequences are also different candidate PDCCHs.
