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 control information sending/receiving method and device are provided for indicating a time-frequency location of a control channel to a terminal device in a 5G NR system or a future evolved LTE system. The method includes: receiving, by a terminal device, broadcast information; determining, from at least two predefined time-domain locations, a time-domain location of a broadcast channel carrying the broadcast information; determining a time-domain location of a control channel based on the time-domain location of the broadcast channel; and performing control channel detection in the determined time-domain location of the control channel.

Abstract: A method includes determining a payload size of a first downlink control information (DCI) format that is the same as a payload size of a second DCI format. The first DCI format is for scheduling an uplink carrier and carries a first carrier indication and the second DCI format is for scheduling a downlink carrier and carries a second carrier indication. The first carrier indication is different from the second carrier indication. The method also includes monitoring DCI in the first DCI format.

Abstract: This application provides an example indication information transmission method. The method includes sending, by a network device, first indication information. The first indication information is used to indicate a time domain position at which second indication information is monitored. The method also includes sending, by the network device, the second indication information. The second indication information includes information about a channel occupancy time of the network device and/or slot format information of one or more slots corresponding to the channel occupancy time.

Abstract: A paging method to improve transmission efficiency of a paging message is provided. The method includes that a first terminal device determines, in a discontinuous reception periodicity, a first paging occasion of the first terminal device. When channel listening on the first paging occasion fails, the first terminal device receives a first paging message in a time window, where a start position of the time window is determined based on the first paging occasion, and the time window includes at least one paging occasion.

Abstract: One example method includes receiving configuration information of a control channel resource set, where the configuration information indicates a quantity of time-frequency resource blocks of the control channel resource set and an offset from a frequency domain center location of a synchronization signal block to a frequency domain center location of the control channel resource set, the synchronization signal block includes broadcast information and a synchronization signal, and the broadcast information includes the configuration information. The control channel resource set is determined based on the quantity of time-frequency resource blocks and the offset, and control information is received within the control channel resource set.
