Abstract
This application provides a technical solution for rank indication, and especially when a CQI number is not configured or a CQI number is 1, a network device configures a rank indication restriction parameter as that at least one of ranks whose index numbers are 0, 1, 2, and 3 is allowed to be reported by the terminal device; or even if the network device does not perform the foregoing configuration, and none of the ranks whose index numbers are 0, 1, 2, and 3 is allowed to be reported, the terminal device may select at least one rank for RI reporting, so as to resolve a problem that a system cannot work. In addition, according to embodiments of this application, bit overheads required for RI reporting may further be reduced.
