Title:
METHOD FOR TRANSMITTING DOWNLINK CONTROL INFORMATION
Document Type and Number:
WIPO Patent Application WO/2019/158005
Kind Code:
A1
Abstract:
Provided in the present application are a method and apparatus for transmitting downlink control information. The method comprises: receiving first downlink control information (DCI) in a search space of a first carrier bandwidth part (BWP), wherein if a type allocated by a frequency domain resource of a first BWP is type 0, an Lf bit frequency domain resource allocation in the first DCI is indicated as an Lf bit bitmap, bits in the Lf bit bitmap correspond to resource block groups (RBG)0 to RBGLf-1 in a second BWP from a high bit to a low bit respectively, and for one bit in the Lf bit bitmap, the allocated resource comprises an RBG corresponding to the bit when the value of the bit is t1. By means of the described method, BWP switching or cross-BWP scheduling may be implemented by means of truncated information domains.
