Abstract

A wireless communication method and a wireless communication device. The wireless communication device includes: one or more processors, configured to generate multiple data flows, the multiple data flows being transmitted to one or more receivers through the first quantity of radio frequency links; and to configure an antenna control parameter, the antenna control parameter being used for dynamically allocating the second quantity of antennas to the first quantity of radio frequency links. The one or more processors configure the antenna control parameter for transmission to be performed, and any one of the second quantity of antennas can be allocated to any one of the first quantity of radio frequency links in a configurable manner.
