Abstract: This application discloses an uplink control information sending method and receiving method, and a communication apparatus. The method includes: a terminal receives first indication information from a network device; and sends at least one type of uplink control information to the network device on an allocated resource, where the first indication information is used to indicate the resource allocated by the network device to the terminal, the allocated resource belongs to at least two basic frequency domain units and is used by the terminal to perform uplink transmission, and the at least one type of uplink control information is mapped to the allocated resource based on the basic frequency domain unit. In this way, even if the terminal can send the uplink control information on only a part of the allocated resource, it can be ensured that the uplink control information is not damaged.

Abstract: Embodiments of this application disclose a signal transmission method, a related device, and a system. The method may include: receiving first indication information sent by a network device, where the first indication information is used to indicate an uplink resource that is allocated by the network device to a terminal in a first bandwidth; the resource indicated by the first indication information includes an integer quantity of resource blocks evenly distributed in a part or all of the first bandwidth; performing uplink transmission in a detected idle second bandwidth; and sending second indication information to the network device, where the second indication information is used to indicate the second bandwidth. This solution can support flexible bandwidth transmission, and can better adapt to a multi-bandwidth scenario supported by a next-generation new radio technology.

Abstract: This application provides a communications method, which includes: performing, by a network device, LBT on a first carrier, and determining a time offset when the LBT is completed, where the first carrier is used to send a first SS Burst Set, and the time offset is a time offset of an actual transmission time of the first SS Burst Set on the first carrier relative to a configured transmission time of the first SS Burst Set; sending, by the network device, the time offset to a terminal; and receiving, by the terminal, the time offset, and performing rate matching on the first carrier based on the time offset. Thus, the terminal may determine the actual transmission time of the first SS Burst Set based on the time offset, to perform the rate matching and accurately parse downlink data, thereby improving reliability of a communications system.
