Abstract: In a data receiving method, a terminal receives first indication information, where the first indication information indicates a target frequency domain position. The terminal determines a first time-frequency resource based on a time domain position of a control resource set and the target frequency domain position, where a frequency domain position of the first time-frequency resource is the same as the target frequency domain position. The terminal receives data on a target time-frequency resource, where the target time-frequency resource includes a second time-frequency resource and a part of resources in the first time-frequency resource; or the target time-frequency resource includes a second time-frequency resource but does not include the first time-frequency resource, where N is a positive integer.

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: 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.
