Abstract: A terminal device receives first downlink control information (DCI) sent by a network device, where the first DCI carries first indication information and second indication information. The first indication information is used to indicate data transmission, and the second indication information is used to indicate an operation mode of an inactivity timer in discontinuous reception (DRX). The terminal device determines an operation mode of the inactivity timer based on the second indication information.

Abstract: Embodiments of this application disclose a path fault detection method and apparatus, a related device, and a storage medium, and belong to the field of communication technologies. In embodiments of this application, a return path is determined according to a forward path. In a path fault detection process, the return path through which a fault detection packet fed back by a tail node to a head node passes includes the forward path. In this way, if the head node receives the fault detection packet fed back by the tail node, it indicates that the forward path is not faulty.

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: 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.

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.
