Title:
RESOURCE DETERMINATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/057524
Kind Code:
A1
Abstract:
A resource determination method and apparatus, relating to the technical field of communications, and used for improving a diversity gain that can be obtained by a PDCCH candidate. The method comprises the following steps: a communication device determines index values of n first CCEs occupied in a first CCE set by the PDCCH candidate in a CORESET, and index values of m second CCEs occupied in a second CCE set, the CORESET being divided into a first physical time-frequency resource area and a second physical time-frequency resource area, the first physical time-frequency resource area being different from the second physical time-frequency resource area in a time domain and/or a frequency domain, the number of the CCEs comprised in the first CCE set being determined according to the number of REGs comprised in a first physical time-frequency resource, the number of the CCEs comprised in the second CCE set being determined according to the number of the REGs comprised in a second physical time-frequency resource, and the sum of m and n being equal to the aggregation level of the PDCCH candidate; and then, the communication device determines, according to the index values of the n first CCEs and the index values of the m second CCEs, a physical time-frequency resource occupied by the PDCCH candidate.
