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: Methods, apparatuses, systems, and computer program products for obtaining full channel knowledge between each transmitter and each receiver when using radio frequency (RF) beamforming are provided. One method described herein includes a method of obtaining channel knowledge at a transmitter with Q transmit antennas for use in beamforming where the transmitter transmits sounding waveforms from B orthogonal basis functions from a transmit array comprised of the Q transmit antennas. In response to the transmitted sounding waveforms the transmitter receives at least one feedback message from a receiver. The feedback message(s) may include an indication of the best MB basis functions plus a gain and phase value for each of the MB basis functions.

Abstract: Systems and techniques for carrier aggregated beamforming using elevation control. A base station determines a first elevation to be used for transmission to a user device using a first carrier, for example, based on information received from the user device. A second elevation, for transmission to the user device based on the second carrier, is determined based at least in part on the elevation information determined for the first carrier. The first and second carriers may be used by the same base station or by different base stations, and using elevation information determined for the first carrier to determine elevation information for the second carrier avoids computation and signaling needed for separate determination of the elevation information for the second carrier.

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.
