Abstract

The embodiment of the application discloses a method, a device and equipment for determining monitoring numbers of PDCCH candidates and non-overlapping CCEs, wherein the method comprises the following steps: determining the PDCCH capacity proportion of a monitoring and scheduling main cell, and determining the cell type of a serving cell; and determining a first limit number of monitoring PDCCH candidates and a second limit number of non-overlapping CCEs per time slot under the condition of supporting cross-carrier scheduling of the main cell according to the PDCCH capacity ratio and/or the cell type of the serving cell. By adopting the embodiment of the application, the complexity of monitoring the PDCCH can be reduced under the condition that the primary cell allows the cross-carrier scheduling of the secondary cell.

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.
