Abstract
Reception and transmission from at least two sets of antenna ports on a high speed train are controlled, wherein the at least two sets of antenna ports are installed at different locations on the high speed train. This involves determining a velocity and the position of each of the antenna ports, and using these as a basis for determining a reception combining scheme and/or transmission scheme from the sets of antenna ports. Signals are transmitted and received from the sets of antenna ports in conformance with the determined reception combining and/or transmission scheme.
