Abstract: Various embodiments provide a communication method. The method includes: determining, by a terminal device, first uplink control information and second uplink control information. In those embodiments, a length of a time domain resource corresponding to the first uplink control information is less than a length of a time domain resource corresponding to the second uplink control information. The first uplink control information or the second uplink control information comprises at least one of hybrid automatic repeat request information, channel state information, and scheduling request information. When the time domain resource corresponding to the first uplink control information overlaps with the time domain resource corresponding to the second uplink control information, the terminal device is configured to transmit third uplink control information on the overlapping time domain resource.

Abstract: A method and an apparatus for assisting a terminal in measuring are provided, which relate to the field of communications network technologies and may implement correct measurement on signal strength of a micro base station, thereby preventing UE from incorrectly determining the signal strength of the micro base station. In embodiments of the present invention, a first base station receives a measurement result for a second base station sent by UE, where the first base station provides a service for the UE; the first base station determines, according to the measurement result, whether a handover operation needs to be started; when the handover operation needs to be started, the first base station instructs the second base station to start up, and hands over the UE to the second base station for a service provided by the second base station.

Abstract: This application provides a method for sending uplink information in a wireless communication system that supports various services such as ultra-reliable and low latency communications (URLLC). A terminal device receives a timing advance coefficient from a network device. The terminal device determines value of a first timing advance based on a first time length and the timing advance coefficient. The first time length is one of at least two different time lengths that are supported by the terminal device. The terminal device sends the uplink information to the network device based on the first timing advance. With this method, the terminal device can uses different timing advances in different scenarios, so that diversified requirements of the fifth generation (5G) mobile communication systems for uplink synchronization are satisfied.
