Abstract

The embodiment of the invention discloses a PDCCH (Physical Downlink Control Channel) sending and receiving methods and related equipment. The PDCCH sending method comprises the steps of: generating acurrent sub-frame comprising a PDCCH, wherein the PDCCH comprises a common control resource set and at least one user-level control resource set, the common control resource set is used for bearing user group control information, the user group control information is used for indicating each user equipment included in a user group and a time-frequency resource position of the user-level control resource set corresponding to the user group, and the user-level control resource set is used for bearing downlink control information of the corresponding user equipment in the user group; and sendingthe current sub-frame to the user equipment. By adopting the PDCCH sending and receiving methods and the related equipment, which are disclosed by the embodiment of the invention, a blind test rangecan be reduced so as to reduce blind test times and reduce the system delay.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for sending and receiving a physical downlink control channel and related equipment. Background technique [0002] With the commercialization of the fourth-generation mobile communication technology and the continuous growth of mobile services, research on the fifth-generation communication technology (5G) has begun worldwide. 5G is a multi-technology integrated communication technology that meets the needs of a wide range of data and connection services through technological change and innovation. 3GPP (3rd Generation Partnership Project, Third Generation Partnership Project) established SI (Study Item, research project) on 5G new air interface research. According to the division of 5G for vertical scenarios, 3GPP mainly conducts research on new air interface technology from three aspects : eMBB (EnhancedMobile Broadband, enhanced wireless broadband), UR...
