    Abstract: A communication method comprises that a user equipment receives quantity information, sent by a transmission reception point TRP, of control information to be sent to the user equipment. N pieces of control information are to be sent to the user equipment, and N is an integer greater than or equal to 1. The user equipment determines, based on the quantity information, that the N pieces of control information need to be detected; and the user equipment detects the N pieces of control information. In an embodiment, processing complexity of the TRP and processing complexity of the user equipment can be reduced in a control information obtaining process.
