Abstract

The embodiment of the present invention discloses a method and device for cross-carrier scheduling physical downlink shared channel. The method includes: receiving downlink control information DCI, wherein the DCI is used to indicate cross-carrier scheduling physical downlink shared channel PDSCH; determining Target co-location QCL information of the cross-carrier scheduled PDSCH; receiving the cross-carrier scheduled PDSCH according to the target QCL information. The embodiments of the present invention can effectively implement cross-carrier scheduling of PDSCH.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for scheduling physical downlink shared channels across carriers. Background technique [0002] The fifth-generation (5G) mobile communication system new air interface (NR, New Radio) introduces large-scale antenna technology, which can better support multi-user-multiple-input multiple-output (MU-MIMO, Multi-User Multiple-Input Multiple-Output ) antenna technology. In order to reduce the equipment cost and baseband processing complexity caused by large-scale antenna arrays, the digital-analog hybrid beamforming technology is used to achieve a rough match between the transmitted signal and the channel. [0003] However, in the cross-carrier scheduling process based on the digital-analog hybrid beamforming technology, there is still a lack of a corresponding cross-carrier scheduling Physical Downlink Shared Channel (PDSCH, Physical Downlink Shared Channel) sol...
