METHOD FOR DETECTING DCI, METHOD FOR CONFIGURING PDCCH, AND COMMUNICATION APPARATUS

Document Type and Number:

WIPO Patent Application WO/2020/029996

Kind Code:

A1

Abstract:

Provided are a method for detecting DCI, a method for configuring a PDCCH, and a communication apparatus. The method comprises: a network side device generating and sending a configuration parameter, wherein the configuration parameter is used for configuring at least one group of candidate resources, with each group of candidate resources bearing one piece of DCI; and a terminal device being used for stopping, when one piece of DCI is detected in a blind manner from each group of candidate resources, the blind detection of the group of candidate resources. In the embodiments of the present application, candidate resources are grouped by means of a configuration parameter, with each group of candidate resources bearing only one piece of DCI, and therefore, in each group of candidate resources, the blind detection of the group of candidate resources can be stopped once a terminal device detects the DCI in a blind manner, such that the blind detection of the remaining resources is avoided, the complexity of blind detection can be reduced, and the network performance can be improved.
