    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.

    Abstract: A signal monitoring method and apparatus are provided. The method includes: determining, by a terminal device based on received configuration information, an index of a first time unit in which a start position of a control channel resource of a control channel is located, where a system frame number in which the first time unit is located is determined based on a first parameter; and monitoring, by the terminal device, the control channel starting from a time domain position corresponding to the index of the first time unit. In this way, the terminal device can monitor the control channel starting from a time unit corresponding to the index of the first time unit, to avoid monitoring the control channel extremely early and reduce overheads.
