Communication method and apparatus

Abstract

This application discloses a communication method and apparatus. The method includes: a network device sending first indication information to a terminal device, the first indication information indicating a cover code length corresponding to a first port among M ports, the M ports belonging to a first port set and / or a second port set, the first cover code length corresponding to the first port set being a first length, and the first cover code length corresponding to the second port set being a second length. According to this method, the network device can indicate the cover code length corresponding to the first port among the M ports to the terminal device, so that the terminal device can flexibly select a port for performing channel estimation and achieve good channel estimation effects.
