Title:
METHOD AND DEVICE FOR TRANSMITTING DOWNLINK CONTROL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2020/087541
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and device for transmitting downlink control information, which may implement the effective transmission of an SSB on an unlicensed spectrum. The method comprises: a network device determining from among M control resource sets a first control resource set that may be used by the network device, the M control resource sets corresponding to candidate Y SSB positions on an unlicensed carrier; the network device sending first downlink control information on a resource of the first control resource set, the first downlink control information being used to determine an SSB position for sending at least one SSB in X SSBs among the Y SSB positions, wherein M, Y, and X are all positive integers, 1≤X<Y, and M≤Y.
