The target monitoring mode includes: A mode for determining the monitored control resource set corresponding to a TCI state in which one QCL-typeD is set; a mode for determining the monitored control resource set corresponding to two or more TCI states in which QCL-typeD is set; The method further includes instructing the terminal device of the transmission mode of the PDCCH by RRC signaling and / or MAC CE signaling.

13. The method according to claim 11 or 12.

14. A communication device, a first determining unit for determining a target monitoring mode of a PDCCH; a second determination unit for determining a set of control resources to be monitored in an overlapping time region corresponding to a plurality of monitoring timings based on the target monitoring mode; The first determination unit further comprises: determining a transmission mode of the PDCCH according to RRC signaling and / or MAC CE activation information; When the transmission mode of the PDCCH is a single frequency network (SFN) transmission and the RRC signaling and / or the MAC CE signaling has two or more TCI states in which QCL-typeD is configured, determining, as the target monitoring mode, a mode for monitoring all of the control resource sets to be monitored that correspond to the TCI states in which at least two QCL-typeD is configured; or When the transmission mode of the PDCCH is single-point transmission, a mode for monitoring all the control resource sets to be monitored corresponding to one TCI state in which one QCL-typeD is set is determined as the target monitoring mode; A communication device comprising:

15. A communication device, a transmitting unit for transmitting instruction information to a terminal device, the instruction information being used to instruct the terminal device of a target monitoring mode corresponding to a PDCCH, and the target monitoring mode being used to determine a control resource set to be monitored in an overlapping time domain corresponding to a plurality of monitoring timings; The transmitting unit further comprises: Instruct the terminal device of a transmission mode of the PDCCH by RRC signaling and / or MAC CE activation information, and when the transmission mode of the PDCCH is single frequency network (SFN) transmission and a TCI state in which two or more QCL-typeDs are set is set in the RRC signaling and / or MAC CE signaling, the target monitoring mode monitors all the control resource sets to be monitored corresponding to the TCI state in which at least two QCL-typeDs are set, or when the transmission mode of the PDCCH is single point transmission, the target monitoring mode monitors all the control resource sets to be monitored corresponding to the TCI state in which one QCL-typeD is set. A communication device comprising:
