Abstract: The present disclosure discloses an example signal transmission method and an example terminal device. One example signal transmission method includes monitoring, by a terminal device and based on a size of first downlink control information (DCI), the first DCI and second DCI that are sent by a network device, where the first DCI is carried on a power saving signal shared by a plurality of terminal devices including the terminal device, and the second DCI is carried on a terminal device specific power saving signal. It is determined by the terminal device and based on at least one of the first DCI or the second DCI, whether to monitor a data channel in a first time period.

Abstract: Example signal receiving methods, signal sending methods, and apparatus are described. One example signal receiving method includes determining at least one time-frequency resource by a terminal device. A wake-up signal or a go-to-sleep signal is monitored on the at least one time-frequency resource, where the at least one time-frequency resource is further used to carry a downlink control channel. The terminal device determines, based on a result of monitoring the wake-up signal or the go-to-sleep signal, whether to start to monitor the downlink control channel from a first time location.

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.

Abstract: This application provides a resource mapping method, a network device, and a terminal device. The method includes: generating, by a network device, control information, where the control information is used to indicate at least one type of the following information: at least one bandwidth region in which at least one frequency domain resource unit is located, a granularity of the frequency domain resource unit, and a location of the frequency domain resource unit in the bandwidth region; and sending, by the network device, the control information to a terminal device. The frequency domain resource unit is a scheduling unit of a frequency domain resource used when the network device and the terminal device transmit a data channel. The granularity of the resource unit corresponds to a granularity of a resource unit used when the network device and the terminal device transmit a control channel.
