Abstract: A resource indication method includes generating, by a network device, first control information, where the first control information is used to indicate a frequency resource occupied to transmit data in N time resource units, and N is a positive integer greater than or equal to 2; and sending, by the network device, the first control information to a terminal device. Therefore, the network device may indicate, for the scheduled N time resource units, the frequency resource occupied to transmit data in the N time resource units.

Abstract: A communication method and a communications device are disclosed. A first device in a communications system separately sends, to a second device, responses used to indicate a transmission result of target data: a first response and a second response. An indication manner of the first response is different from an indication manner of the second response. This approach can improve flexibility of a response indication manner. Therefore, the communications system can flexibly adjust indication manners of responses sent at different times to ensure indication precision of the responses while reducing transmission resources of the responses.

Abstract: The application provides method for communicating channel state information (CSI) in a communication network. The method is as follows: An apparatus determines whether a length of CSI is less than a preset length; and adds a padding bit to the CSI when determining that the length of the CSI is less than the preset length, where a length of CSI obtained by adding the padding bit is consistent with the predetermined length. The CSI obtained by adding the padding bit is communicated in the communication network.

Abstract: A method, a device, and a system for triggering a scheduling request (SR) to meet quality of service (QoS) requirements of different services in a New Radio (NR) vehicle to everything (V2X) system and to avoid or reduce unnecessary SR triggering. The method includes that a network device sends a first message to a terminal device, where the first message includes a first identifier and one or more configuration parameters corresponding to the first identifier. The first identifier is of a first logical channel, and the first logical channel is of a sidelink (SL) radio bearer. Alternatively, there is a mapping relationship between the first identifier and the first logical channel.

Abstract: A terminal receives a power saving signal sent by a network device, where the power saving signal indicates N time units, and where N is greater than 0. The terminal determines a state of the terminal in a first time period corresponding to the N time units on a first frequency domain resource and a state in a second time period corresponding to the N time units on a second frequency domain resource. The state of the terminal includes a sleep state or a wake-up state. The sleep state indicates that the terminal monitors no first signal, and the wake-up state indicates that the terminal monitors a first signal based on a configuration parameter.
