    Abstract: Systems, methods, apparatuses, and computer program products for determining transmit weights are provided. One method includes selecting users to pair for multi-user multiple input multiple output transmission, calculating multi-user multiple input multiple output (MU-MIMO) transmit weights in a communication system employing an analog electrically steered array with Q antennas, applying the multi-user multiple input multiple output weights to the transmitted signals, and transmitting the weighted signals from an antenna array. The calculating may include calculating the MU-MIMO transmit weights so that a sum of power across a same element of the selected users' weight vectors is equal on all of the antennas and one of either sum throughput across users or sum signal to interference plus noise ratio (SINR) across users is maximized.

    Abstract: An example technique may include determining, by a user device, a reference precoding vector for each of a plurality of rank indications, selecting, by the user device, a rank indication of the plurality of rank indications for data transmission based on reference signals received from the base station and the reference precoding vector for each rank indication, sending, from the user device to the base station, the selected rank indication for data transmission, determining, by the user device, one or more channel quality indications (CQIs) for the data transmission based on the reference signals received from the base station, the selected rank indication and the reference precoding vector for the selected rank indication, and sending, by the user device to the base station, the determined one or more channel quality indications (CQIs) for the selected rank indication.

    Abstract: Various communication systems may benefit from managing signal interference. For example, certain wireless communication systems may benefit from a dynamic time division duplex system involving slot allocation. A method includes allocating, by an access point, in a time division duplex frame a plurality of radio resource slots, each one of the plurality of radio resource slots being allocated for a downlink or an uplink transmission, and determining that the allocation of the downlink or uplink transmission should be changed. The method also includes applying a permutation pattern to re-allocate at least one of the plurality of radio resource slots for the downlink or uplink transmission.

    Abstract: Systems and techniques for elevation beam design. Characteristics, such as number, distribution, and geographical location of elements subject to interference by elevation beams of a base station are analyzed, and a configuration for an antenna array is determined so as to create a set of elevation beams directed so as to avoid interference with the elements subject to interference by the base station. Configuration may, for example, include configuration of the antenna array so as to create a set of elevation beams exhibiting nulls and sidelobes in appropriate locations and at appropriate angles so as to avoid interference.
