Problems solved by technology

[0008] Since different search space sets can be configured with separate detection periods, different aggregation levels, and the number of PDCCH candidates, in some slots, the maximum number of detections required for the PDCCH candidates configured by the base station for the UE will exceed the maximum number of PDCCH detections by the UE. limit, which may lead to an increase in the number of times the UE detects the PDCCH

Abstract

The embodiment of the invention provides a detection method, a sending method and equipment for a physical downlink control channel. The method comprises the steps of determining the number of times of detection required by all PDCCH candidates configured in the target time slot; when the maximum detection frequency of the terminal on the target time slot is exceeded, determining PDCCH (Physical Downlink Control Channel) candidates to be detected, so that the sum of the detection times of the PDCCH candidates needing to be detected is not greater than the maximum detection times of the terminal in the time slot; the terminal only detects the PDCCH on the PDCCH candidate needing to be detected, and the base station also sends the PDCCH to the terminal on the PDCCH candidate needing to be detected, so that the terminal can reduce the detection times of the PDCCH.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a detection method, transmission method and equipment of a physical downlink control channel. Background technique [0002] The physical downlink control channel can be used to indicate the PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) scheduling corresponding to the UE (User Equipment, User Equipment) or when the PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) scheduling to be sent frequency resources and transmission parameters, to obtain these messages, the user terminal needs to first detect the downlink control channel. A PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) is transmitted on n consecutive CCEs (Control Channel Element, Control Channel Element). There are 5 formats of PDCCH, corresponding to aggregation levels {1, 2, 4, 8, 16 }. The aggregation level represents t...
