Abstract: This disclosure provides an information transmission method and a terminal. The information transmission method includes: receiving DCI; determining a target bit sequence of to-be-transmitted HARQ-ACK information, where the to-be-transmitted HARQ-ACK information includes first information, and the first information is HARQ-ACK information that has not been successfully reported before and that is triggered by the DCI; and transmitting the to-be-transmitted HARQ-ACK information by using the target bit sequence.

Abstract: Embodiments of this application disclose a DRX configuration method for sidelink and a device, where the method includes: determining, by a terminal device, DRX configuration information; and performing DRX configuration according to the configuration information. In the embodiments of this application, a terminal device can determine DRX configuration information, and perform DRX configuration according to the determined configuration information, thereby implementing power saving for terminal devices in sidelink.

Abstract: A sidelink discontinuous transmission (DTX) method and apparatus, a sidelink discontinuous reception (DRX) method and apparatus, and a terminal device, and relates to the field of communication technologies. The sidelink DTX method and apparatus, the sidelink DRX method and apparatus, and the terminal device are utilized, so that when user terminals communicate with each other through a sidelink, data scheduling/transmission is monitored, or data scheduling/transmission is received, or it is allowed to perform data scheduling/transmission to a first user terminal, or data scheduling/transmission to the first user terminal is performed under control of a timer based on a DRX mechanism only during running of a target receive timer in the timer.

Abstract: A terminal device sends first information to a cloud device, where the first information indicates a posture and a location of the terminal device at a first moment. Then, the terminal device receives information about a first field of view image from the cloud device, where the first field of view image is a field of view image corresponding to the posture and the location of the terminal device at the first moment. The terminal device displays an image within a field of view range of the terminal device at a second moment based on the information about the first field of view image and a posture change and a location change of the terminal device from the first moment to the second moment.

Abstract: A method and an apparatus for tracking a clock source are disclosed. The method includes determining a best clock source to be tracked by a device according to a best clock source tracked by a slave candidate port in the device and distributing the best clock source tracked by the device through a master candidate port in a master state. Through the embodiments of the present disclosure, the clock source selection of the device converges quickly. Moreover, because the slave candidate port is determined according to the network planning, the planning of the transport network is observed.

Abstract: A method of clock transmission between networks and an apparatus of clock transmission are disclosed, in which a second group of information corresponding to a clock transferred by a first network equipment based on a first protocol, and the second group of information corresponding to a clock transferred by a second network equipment based on a second protocol are acquired, and a source selection is performed in a united way by adopting a source selection manner based on the second protocol according to the second group of information. Therefore, the equipment in different types of networks can conveniently select a clock with a higher class from clocks transferred based on different protocols, so as to realize a normalization management on the clocks transferred based on different protocols.
