Abstract: The present disclosure discloses example power control methods and apparatuses. One example method includes determining a transmit power of a control channel and a first data subchannel, where the control channel and the first data subchannel completely overlap in time domain and do not overlap in frequency domain. A transmit power of a second data subchannel is determined to be the same as the transmit power of the control channel and the first data subchannel, where the second data subchannel and the control channel overlap in frequency domain and do not overlap in time domain. The control channel and the first data subchannel are sent to a second terminal apparatus at the transmit power of the control channel and the first data subchannel. The second data subchannel is sent to the second terminal apparatus at the transmit power of the control channel and the first data subchannel.

Abstract: Example radio link monitoring methods and apparatus are described. One example method includes performing radio link monitoring (RLM) in a second bandwidth part (BWP) by a terminal device. The terminal device receives first switching information from a network device that is used to indicate that an active BWP includes a first BWP, and switches from the second BWP to the first BWP based on the first switching information. The terminal device removes a measurement result obtained by performing RLM in the second BWP, where the measurement result includes a quantity N1 of one or more out of synchronization (OOS) states or a quantity N2 of one or more in synchronization (IS) states. RLM is performed in the first BWP.

Abstract: A time-to-digital converter includes N stages of converting circuits, where N2, and N is an integer. Each stage of the converting circuit includes a first delayer and an arbiter; an output end of the first delayer in each stage of the converting circuit outputs a delayed signal of the stage of the converting circuit; and the arbiter in each stage of the converting circuit receives a sampling clock and the delayed signal of the stage of the converting circuit, and compares the sampling clock with the delayed signal to obtain an output signal of the stage of the converting circuit. The first delayer in each stage of the converting circuit includes at least one first delay cell circuit with a first time unit. The first delayer in any stage of the converting circuit includes a less number of first delay cell circuits than the first delayer in a next stage of the converting circuit.

Abstract: Disclosed are a zoom method and an apparatus, to improve zoom accuracy of a camera module. The method includes: controlling, based on a target focal length, the lens to move in different subregions when the lens moves in an operation region, and determining position information of the lens based on a position detection relationship of a subregion in which the lens is currently located. The lens is controlled to move based on a position that is of the lens and that is detected when the lens moves, so that the lens can more accurately stop at a position corresponding to the target focal length. This helps improve focusing accuracy of the camera module.
