The invention discloses a transmission and detection method, network equipment and terminal of a physical downlink control channel. The method for transmitting the physical downlink control channel includes: transmitting the physical downlink control channel PDCCH to the terminal, wherein the PDCCH transmits a format of downlink control information DCI, the DCI supports the transmission of terminal-specific control information and group common control information, the The terminal-specific control information includes at least a terminal-specific energy saving signal, and the group common control information includes at least a group common energy saving signal. The scheme of the present invention can implement one DCI format, support the transmission of two energy-saving signals, and reduce the complexity of configuration.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission and detection method, network equipment and terminal of a physical downlink control channel. Background technique [0002] In the 5G NR (New Radio, new radio) system, the current UE (User Equipment, user equipment or terminal) has three working states: RRC_IDLE (radio resource control idle state), RRC_Inactive (radio resource control inactive state) and RRC_Connected (radio resource control connected state), the UE in the first two states needs to monitor the paging signal. When the UE receives the paging signal, it means that there is data transmission on the network side, and the UE needs to enter the RRC_Connected state to receive downlink data. In the RRC_Connected state, the UE needs to continuously monitor the downlink control channel PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) to learn the transmission informat...
