Abstract: Example methods and apparatus for transmitting a signal transmission method and a device are disclosed. One method includes transmitting a signal based on a predefined transmission pattern by a communications device. The transmission pattern defines that a non-first downlink timing boundary in a downlink time domain unit is later than or earlier than a first downlink timing boundary is defined, or that an uplink timing boundary in an uplink time domain unit is earlier than or later than the first downlink timing boundary.

Abstract: This application provides a data communication method, a terminal, and a base station. In one embodiment, the terminal receives a first demodulation reference signal based on a first physical resource block index. The first physical resource block index is determined based on a first location in frequency domain, and the first demodulation reference signal is used to demodulate a data channel on which system information is located. The terminal sends and/or receives a second demodulation reference signal based on a second physical resource block index. The second physical resource block index is determined based on a second location in frequency domain, and the second demodulation reference signal is used to demodulate a data channel other than the data channel on which the system information is located.

Abstract: Example control channel resource indication methods, user equipment, and network devices are described. One example method includes sending a preamble signal sequence by a user equipment. The user equipment receives higher layer signaling corresponding to the preamble signal sequence. The higher layer signaling is indicated by downlink control information carried in a common search space. A time-frequency resource detected by the user equipment when determining a control channel includes the common search space and user equipment-dedicated search space. The user equipment determines frequency domain resource location information of the user equipment-dedicated search space based on the higher layer signaling. The frequency domain resource location information includes a quantity of frequency domain resource units occupied by the user equipment-dedicated search space in frequency domain and a location of the frequency domain resource unit.
