Abstract: Example communication methods and apparatus are described. One example method includes performing first listen before talk (LBT) and sending a first data packet on a first uplink burst after the first LBT succeeds. A second contention window size is determined based on the first contention window size and a first reference time unit. Second LBT is performed based on the second contention window size. The first contention window size is used for a LBT previous to the second LBT, the first reference time unit is later than the second reference time unit corresponding to the first uplink burst. The first reference time unit is a time unit for determining the second contention window size, or a starting time unit of a second uplink burst corresponding to the second LBT. The second reference time unit corresponding to the first uplink burst is a time unit in the first uplink burst.

The detecting method includes: determining a candidate resource set within virtual downlink resources of a current cell. The candidate resource set can include at least one candidate resource carrying a common control channel of the current cell. A detection is performed on at least one candidate resource in the candidate resource set, so as to acquire the common control channel of the current cell. In the embodiments of the present invention, a selection range of resources for transmitting a common control channel is extended, so that inter-cell interference of the common control channel can be coordinated, and a detection performance of the common control channel can be improved.

Abstract: A network device sends indication information to a terminal device, to indicate a reference position of a starting symbol of a data channel. The network device sends a physical downlink control channel to the terminal device. Then the network device sends the data channel to the terminal device, or the network device receives the data channel from the terminal device.

Abstract: Embodiments of the present application provide a method for acquiring information of access resources, a terminal device, and a base station. A terminal device detects a synchronization signal of a cell to be accessed by the terminal device. The terminal device further receives a broadcast channel of the cell on a broadcast channel resource. The terminal device then determines a resource on which the cell is located according to resource indication information carried in the broadcast channel. The broadcast channel resource corresponds to an actual access resource, and the synchronization signal is detected on the actual access resource. The actual access resource is one of a plurality of candidate access resources of the cell. The resource indication information indicates a location relationship between the actual access resource and the resource on which the cell is located.

Abstract: This application provides a link failure detection method. A terminal device measures quality of radio links corresponding to reference signals in a set. When any one of the radio links is of poor quality, and not all of the radio links are of poor quality, the terminal device notifies a network device of the radio link of poor quality. After determining the radio link of poor quality, the network device does not send and/or receive communication data between the network device and the terminal device on the radio link of poor quality, or does not send and/or receive, on the radio link of poor quality, communication data that does not satisfy a service requirement.
