Abstract: Example synchronization signal sending and receiving methods and apparatus are described. In one example method, a terminal device determines a target frequency resource. A frequency domain position of the target frequency resource is determined based on a frequency domain position offset and a frequency interval of synchronization channels. The terminal device receives a synchronization signal by using the target frequency resource.

Abstract: Embodiments of the present invention provide a resource mapping method and an apparatus, and relate the communications field, so as to flexibly implement resource mapping of a channel or a signal. First information is obtained. The first information is used to indicate a cyclic shift start resource block location or a cyclic shift end resource block location for resource mapping of a first channel or a first signal in a resource block cyclic shift manner in a bandwidth used by user equipment. A resource mapping location of the first channel or the first signal in the bandwidth used by the user equipment is determined according to the resource block cyclic shift manner and the first information. The first channel or the first signal is received or sent at the resource mapping location. The resource mapping method and the apparatus are used to map a resource.

Abstract: Embodiments of this application provide a control channel configuration method, a base station, and a terminal device. The method includes: determining, by a base station, a configuration of a time-frequency resource unit from at least two configurations of a time-frequency resource unit of a control channel; and sending, by the base station, indication information to a terminal device, where the indication information is used to indicate the configuration of the time-frequency resource unit, and the at least two configurations of a time-frequency resource unit include a first configuration and a second configuration. In the embodiments of this application, the base station can flexibly configure the time-frequency resource unit of the control channel. In addition, flexibly configuring a time-frequency resource unit can reduce a probability that time-frequency resource units of different structures are blocked, thereby reducing complexity of detecting the control channel by the terminal device.
