1. An antenna port indication method, comprising:
transmitting a port indication message to a network-side device; wherein the port indication message carries at least any one of the following port indication information:
bitmap information or combination coefficient information for indicating ports selected by a terminal;
a first parameter for indicating the ports selected by the terminal, wherein a first value range of the first parameter is determined based on the number X of transmission ports of the network-side device, the number K of ports selected by the terminal and a sampling interval e for adjusting each K ports; or
a second parameter for indicating the ports selected by the terminal in a first polarization direction and a third parameter for indicating the ports selected by the terminal in a second polarization direction.
