Abstract: A communication method, a terminal device, and a network device includes detecting, by a network device in a first time unit, a reference signal or data received from a terminal device to the network device in a second time unit, and sending, by the network device, first indication information in a third time unit after the first time unit, where the first indication information indicates a resource for sending the data by the terminal device. Furthermore, the terminal device sends the data to the network device in a grant-free transmission manner.

Abstract: The application provides manner for communicating channel state information (CSI) in a communication network. A preset length is used for equalizing lengths of CSI to be reported. The preset length is determined based on a quantity of CSI-reference signal (RS) ports. A communication device determines whether a total length of one or more indication information items to be included in the CSI is less than the preset length. If the total length of the one or more indication information items to be included in the CSI is less than the preset length, the communication device adds one or more padding bits, to obtain a CSI bit sequence including the one or more indication information items and the one or more padding bits. A total length of the CSI bit sequence is consistent with the preset length. The communication device then outputs the CSI bit sequence.

Abstract: Embodiments relate to the field of communications technologies, and in particular, to a device to device (D2D) signal frequency hopping method and a base station. The method includes: obtaining, by the base station, a first frequency hopping parameter, where the first frequency hopping parameter is a frequency hopping parameter of a physical uplink shared channel (PUSCH). The method also includes sending, by the base station, the first frequency hopping parameter to D2D user equipment, and instructing, by the base station, the D2D user equipment to use the first frequency hopping parameter to perform frequency hopping on a D2D signal.

Abstract: A paging message sending method includes determining, by a first terminal, that a second terminal is paged. The method further includes sending, by the first terminal to the second terminal, a first message. The first message is used to enable the second terminal to determine that the second terminal is paged.

Abstract: In the embodiments of the present invention, a first-type terminal increases signal transmit power and/or a second-type terminal decreases signal transmit power, or when selecting a resource location for signal transmission, a terminal may exclude a resource location that is close in frequency domain to and located in a same time interval as a resource location reserved by another terminal of a different type, or resource locations used by different types of terminals to transmit signals are separated by a resource location occupied by a guard band, to reduce in-band emission interference.

Abstract: A path switching method includes: determining, by a base station, to switch a first terminal device from a first communication link to a second communication link, and sending, to the first terminal device by using a second terminal device, access information required by the first terminal device to access the base station, so that the first terminal device establishes the second communication link to the base station based on the access information. In the method, the second terminal device may release the first communication link before or after the second communication link is established, or may release the first communication link in a process of establishing the second communication link.
