Abstract: Embodiments of the present invention provide a communication method, an apparatus, and a system. The method includes: generating, by a base station, first indication information, where the first indication information is used to indicate configuration information of a first resource; generating, by the base station, second indication information, where the second indication information is used to indicate a relationship between a second resource and the first resource to a terminal; and sending, by the base station, the first indication information and the second indication information, so that the terminal determines its own receiving resource or sending resource. When the base station indicates the receiving resource or the sending resource of the terminal, according to the technical solutions provided in the embodiments of the present invention, resource indication overheads can be reduced.

Abstract: Embodiments of the present disclosure includes example subframe configuration methods and related devices. One example method includes configuring, by a network-side device, a target subframe, where the target subframe includes at least one sounding reference signal (SRS) symbol used to send an SRS signal. The network-side device can then send first configuration signaling to a terminal device, where the first configuration signaling includes a resource configuration of the target subframe or an SRS configuration of the target subframe.

Abstract: A clock generation circuit and a clock signal generation method are disclosed. In the method, a direct current bias circuit in a first clock source superimposes a first direct current voltage on a first clock signal output by a first oscillation circuit, to generate a second clock signal; and a logical operation is performed on the second clock signal and a third clock signal that is generated by a second clock source, to generate a fourth clock signal. The fourth clock signal is used as a signal output by a clock generation circuit. In the method, when the first oscillation circuit cannot normally work, the clock generation circuit can still output a correct clock signal. This avoids clock signal interruption when switching is performed from the first clock source to the second clock source.
