摘要： This application relates to the field of communications technologies, and discloses a channel quality information determining method, an apparatus, and a system. The method includes: A terminal device obtains a configured TBS, and determines channel quality information of each of K segments of frequency domain resources based on the TBS and a time domain resource range. A frequency domain resource of the terminal device is divided into N segments, where both N and K are integers greater than or equal to 1, and K is less than or equal to N. In embodiments of this application, the TBS is fully considered when the channel quality information is determined, so that a network device properly determines, based on the channel quality information, a frequency domain resource used to transmit a data packet.
