Description

Method, device and equipment for determining monitoring number of PDCCH candidates and non-overlapping CCEs (control channel elements)
Technical Field
The present application relates to the field of computer technologies, and in particular, to a method, an apparatus, and a device for determining monitoring numbers of PDCCH candidates and non-overlapping CCEs.
Background
For the same-cell scheduling and cross-carrier scheduling, the protocol specifies the maximum number of candidate Physical Downlink Control Channel (PDCCHD) candidates and the maximum number of non-overlapping Control Channel 1 elements (CCEs) that need to be monitored in each timeslot.
However, in the existing conclusion, one cell can be scheduled only by the cell or only by cross-cell scheduling, and the situations of both the cell scheduling and the cross-cell scheduling cannot occur. Especially, under the condition that the primary cell is allowed to be cross-carrier scheduled by the secondary cell, the PDCCH candidate limit and the non-overlapping CCE limit which need to be monitored in each time slot cannot be determined, and the cross-cell scheduling of the primary cell needs to monitor the PDCCH candidate limit and the non-overlapping CCE limit, which results in higher complexity of monitoring the PDCCH.
