摘要： One or more quality indicators are established at a first communication device having antenna elements. The quality indicators indicate a quality of one or more communication links between the first communication device and one or more second communication devices. A modification is determined according to the quality indicators, where the modification describes at least one adjustment of one or more modulation features. A time boundary indicator indicating a boundary of a time period is received. At least some of a set of signals are modulated in accordance with the modification and in response to the time boundary indicator, where a signal is associated with an antenna element. The set of signals is sent from the antenna elements to yield a transmitted signal.

摘要： In a cell phone telecommunication system having a macrocell and a small cell coextensive with or adjacent to the macrocell and sharing a common frequency band, interference can occur between a user device operating in the small cell, the local base station operating the user devices in the small cell on one hand and another user device serviced by a main base station for the macrocell. In order to reduce this interference, the shape of the transmission beam from at least one of the user devices or base stations is shaped into a narrow beam steered to be directed at the respective receiving unit. Alternatively, the shape of the transmission beam has a null point and the beam is steered so that its null point is directed toward the affected unit.

摘要： A method and apparatus has been developed to reduce SAR for a mobile device by designing appropriate matching circuits between each antenna and its power amplifier. In the presence of such matching circuits the normal phase adjustments may be carried out to provide a preferred safe SAR level that can be maintained during phase adjustment without sacrificing TRP.

摘要： Disclosed are devices, systems, apparatuses, methods, products, and other implementations of GNSS repeater systems and methods for improving phase and frequency alignment of RF signals transported through fiber optic communication channels. Acquired RF signals are processed at a remote outdoor unit, where they are digitized, formatted into a CPRI frame, and timestamped. The timestamped CPRI frame is then transported over a fiber optic communication channel to an indoor head end unit. The indoor head end unit extracts timestamp and digitized RF signal from the CPRI frame. The timestamp is then used to synchronize a base transceiver station (BTS) and a precision time protocol (PTP) grand master with the remote outdoor unit.
