In a wireless communication system, signals within a connection on a wireless interface are transmitted exclusively in a packet-switched manner between a user station and an access device located on the network. The user station signals a need to measure signals to the access device, the access device sends measurement signaling to the user station, and the user station measures signals of at least one additional access device located on the network at a second frequency range while receiving data packets within the connection at a first frequency range based on the received measurement signaling, the second frequency range being disjunct from the first frequency range.
