Title:
CHANNEL RESOURCE TRANSMISSION METHOD, APPARATUS, NETWORK DEVICE, TERMINAL, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/203431
Kind Code:
A1
Abstract:
Disclosed in the present invention is a channel resource transmission method, an apparatus, a network device, a terminal, and a system. The method comprises: a network device sends a candidate control channel in at least one search space to a terminal device; wherein an association relationship exists among at least one search space and at least two transmission configuration indicator states, and a resource occupied by the candidate control channel is determined according to a transmission configuration indicator state corresponding to the candidate control channel as well as a control resource set corresponding to the transmission configuration indicator state corresponding to the candidate control channel. The present invention solves the technical problem in related technologies where, due to configuration on a frequency domain resource for a PDCCH being obtained according to a number of candidate channels in a search space, detection performed by a UE on a PDCCH on said frequency domain resource will thereby cause subsequent inability to correctly receive a PDCCH.
