Abstract: This application provides a communication method and apparatus. The method includes: receiving, in a first control resource set or a second control resource set, first signaling from the network device, and adjusting the second control resource set based on the first signaling, where the first signaling indicates a quantity of symbols occupied by the second control resource set. Signaling that indicates a quantity of symbols of a CORESET is sent in a control resource set (for example, the first control resource set or the second control resource set). This helps implement flexible indication of a CORESET resource, so that a service requirement can be more quickly matched, and user experience can be improved.

Abstract: This application provides a physical broadcast channel sending/receiving method and an apparatus. In the method, after receiving two broadcast channel signals on two corresponding physical broadcast channels at two time-frequency resource locations, the terminal device determines that information other than an offset of a corresponding time-frequency resource location is the same in two pieces of broadcast information carried in the two broadcast channel signals, obtains a time offset difference between the foregoing two time-frequency resource locations, and generates a scrambling sequence based on the time offset difference; and the terminal device separately descrambles the two broadcast channel signals based on the scrambling sequence and a preset scrambling sequence, thereby implementing joint decoding on the two broadcast channel signals, to obtain one piece of broadcast information.
