Title:
RESOURCE DETERMINATION METHOD AND RESOURCE DETERMINATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/120135
Kind Code:
A1
Abstract:
A resource determination method and a resource determination apparatus. In the method, a plurality of search spaces are associated with one another. For example, the plurality of search spaces carry the same downlink control information, or jointly transmit the same downlink control information. A terminal device determines an uplink control channel resource on the basis of a CCE starting position of a search space among the plurality of search spaces that satisfies a preset condition, such that a unique uplink control channel resource can be determined. In addition, further provided is a channel transmission method, wherein the method can add certain limitation to the plurality of search spaces that are associated with one another, for example, the ratios of the CCE starting position of each search space to the number of CCEs in a control resource set corresponding to each search space are all the same, such that a unique uplink control channel resource can be determined to carry out channel transmission.
