Problems solved by technology

[0008] When multiple DCIs need to be transmitted to the same UE in the same time slot, such as downlink scheduling DCI (DL scheduling DCI), uplink grant DCI (UL grant DCI), cross carrier / slot scheduling DCI (cross carrier / slot scheduling DCI) etc. If two-level DCI is used, how to effectively transmit the first-level and second-level DCI while reducing the complexity of blind detection for users, the prior art has not yet given a specific solution

Abstract

The present invention provides a transmission method, detection method, device and equipment of a hierarchical control channel. By adding DCI type indication information in the first level of two-level DCI, it can indicate the type of DCI currently transmitted, so as to simplify the terminal side. detection complexity. In addition, the detection sequence of the second-level DCI may also be notified or preset. Furthermore, the embodiment of the present invention also provides a search space design, which further simplifies the detection process at the terminal side.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a transmission method, detection method, device and equipment of a hierarchical control channel. Background technique [0002] In the design of the 5th generation mobile communication system (5G) new air interface (NR), a two-stage (2-stage) control channel design is proposed to obtain processing time gain, control channel splitting gain, and control channel beamforming gain Etc., the possible implementation methods are as follows: [0003] 1) Both the first-level downlink control information (DCI, Downlink Control Information) and the second-level DCI are transmitted in the physical downlink control channel (PDCCH, Physical Downlink Control Channel) area, and the two-level DCI is transmitted in different OFDM ( OFDM, Orthogonal Frequency Division Multiplexing) symbol transmission, can have some gain in delay processing; [0004] 2) Both the first-level DCI and the...
