A mobile communication device that is configured to cancel interference within received millimeter wave band signals. The device includes a receiver circuit that is configured to receive a millimeter wave band signal, adjust gain provided to the millimeter wave band signal at a first amplifier, cancel interference in millimeter wave band signal after gain is adjusted by the first amplifier, and adjust gain provided to the millimeter wave band signal at a second amplifier after interference is cancelled.

Millimeter wave (mmWave) system and methods

This disclosure describes systems, methods, and devices related to a distributed relay. The distributed relay may utilize beamforming and/or a specific physical arrangement of transmit and receive antennas to ensure a high isolation between antennas. The distributed relay may further facilitate the concurrent operation of two different intermediate frequency (IF) chains to support communications between a network entity and user device, receiving and transmitting data on each of the two IF chains independently of one another.

Millimeter wave (MMWAVE) system and methods

Aspects of mmWave beam tracking and beam sweeping are described, for example, spatial searching operations, directional beam forming, complex channel measurement operations, and adaptive power savings. Some aspects include using priori information for mmWave beam tracking and beam sweeping. Some aspects include using priori information to modify a superset of beam criteria to obtain a subset of beam criteria, select a spatial region according to the subset of beam criteria, and initiate a spatial searching operation within the spatial region for establishing a communication link. Some aspects include obtaining complex channel measurements of beams and combining the measurements with priori information to determine a beam for use in a communication link. Some aspects include providing signals from Nover Kinput/output (IO) links and receiving signals over KIO links, and combining signals received over the KIO links, using a compression matrix, to generate signals over K IO links.

Millimeter wave beam tracking and beam sweeping

A remote radio head as part of a small cell or home gateway communication system, comprising a baseband module and a radio unit, the baseband module and the radio unit being configured to be placed on opposing sides of a lossy medium, such as a window. The baseband module is configured to receive and transmit an information signal from a user equipment inside of a structure and the radio unit configured to receive and transmit an information signal from a user equipment or a base station node outside of the structure. The baseband module is further configured to perform signal modulation and demodulation and up-conversion and down-conversion, and the radio unit is configured to perform up-conversion and down-conversion. The baseband module and the radio unit are capable of receiving and transmitting wireless intermediate frequency signals through a lossy medium, so as to avoid signal attenuation, particularly for mmWave wireless signals.

The present disclosure relates to an antenna array arrangement including a plurality of antenna arrays. Each antenna array includes a plurality of antenna elements. At least two of the plurality of antenna arrays are staggered along at least one of a horizontal dimension or a vertical dimension. Adjacent elements of a projection of the antenna elements of the antenna array arrangement onto a horizontal dimension or a vertical dimension have a distance that is in the order of half of a wavelength of a radio signal to be transmitted from the antenna array arrangement.
