Communication method and apparatus

Abstract

This application relates to a communication method and apparatus. An AP MLD receives first downlink data from a current AP MLD, where the first downlink data is data encrypted using a first key negotiated by the current AP MLD and a non-AP MLD, and a target AP MLD is an AP MLD of the non-AP MLD after a basic service set BSS transition. The target AP MLD performs lower-medium access control (LMAC) layer processing and physical layer processing on the first downlink data, to obtain second downlink data. According to the method and the apparatus disclosed herein, roaming performance of the non-AP MLD can be improved.
