Abstract: A wireless communication device includes a wireless interface for conducting wireless communications with a network access node of a wireless network, the wireless interface having uplink and downlink beam forming capabilities. The wireless communication device further includes a control circuit configured to detect a predetermined condition and, in response to the detection, temporarily operate the wireless interface without beam correspondence between uplink and downlink operations; and transmit a message to the network access node that beam correspondence is not used by the wireless communication device.

Abstract: A cellular multiple-input and multiple-output, MIMO, system comprises a base station having a plurality of antennas. Pilot signals are received by the base station in each frame of a sequence of frames (60). The base station analyzes the pilot signals to determine radio channel properties of radio channels between respectively each one of a plurality of terminals and the base station. The sequence of frames (60) comprises frames of a first frame type (61, 63, 64, 68) and frames of a second frame type (62, 69). Each frame of the second frame type (62, 69) have a greater number of time slots in which the base station receives the pilot signals than each frame of the first frame type (61, 63, 64, 68). The frames of the second frame type (62, 69) are included periodically in the sequence of frames (60).

Abstract: The present invention relates to a method for operating a base station (21) in a wireless radio network. The base station (21) comprises a plurality of antennas (22) for transmitting radio frequency signals between the base station (21) and a user equipment (UE1, UE2, UE3). According to the method, at each antenna (22) a training signal sent from the user equipment at a first point in time (t1) is received and for each antenna a corresponding first configuration parameter (P1) is determined based on the training signal received at the corresponding antenna at the first point in time (t1). Furthermore, at each antenna (22) a training signal sent from the user equipment at a second point in time (t2), which is different from the first point in time (t1), is received and for each antenna (22) a corresponding secand configuration parameter (P2) is determined based on the training signal received at the second point in time (t2). For each antenna (22) a corresponding predicted configuration parameter (P3) is determined based on the first and second configuration parameters (P1, P2).
