Determining radio channel metrics
A method is provided to determine radio channel metrics for radio communication between a plurality of remote radio heads and a wireless device. The method is performed in a remote radio head controller and comprising: selecting a first set of at least one remote radio head; selecting a second set of at least one remote radio head; configuring at least one switch such that only the remote radio heads of the first set communicate radio signals using a first radio branch; configuring at least one switch such that only the remote radio heads of the second set communicate radio signals using a second radio branch; determining a first radio channel metric for radio communication with the wireless device using the first radio branch; and determining a second radio channel metric for radio communication with the wireless device using the second radio branch.
