The method comprises determining whether a received signal strength of the radio signals of each of the one or more beams exceeds a first evaluation threshold, identifying a sub-set of the set of detected beams of radio signals which can be used to receive data carried by the radio signals of the beam for which the received signal strength exceeds the first evaluation threshold, and entering a relaxed radio measurement state in which the communications device reduces an amount of attempted measurements of the plurality of beams of radio signals compared with a normal state according to one or more relaxed measurement state criteria.

Abstract: A method of precoding the power of a channel of a ground terminal in communication with a satellite. The ground terminal is subject to limitations in terrestrial mobile network rates and other congestion conditions. An actual signal-to-interference-plus-noise ratio is calculated and adjusted according to a desired signal-to-interference-plus-noise ratio for a predetermined time epoch. The actual signal-to-interference-plus-noise ratio is adjusted while considering the competing requirements of both: the energy of the difference between the successive actual/desired signal-to-interference-plus-noise ratio levels and the energy of the control sequences. The actual signal-to-interference-plus-noise ratio is autonomously converged with the desired with the signal-to-interference-plus-noise ratio, subject to the limitations in terrestrial mobile network rates and other congestion conditions, by dynamically minimizing covariance error and predicting gain for the epoch.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may communicate, using a first set of active antenna elements of an antenna array, during a first time period. The network node may activate a second set of active antenna elements based on a dynamic antenna set switching scheme, wherein the second set of active antenna elements includes at least one active antenna element not included in the first set, wherein a difference between a first main lobe property and a second main lobe property satisfies a main lobe threshold, and wherein a difference between a first side lobe property and a second side lobe property satisfies a side lobe threshold. The network node may communicate, using the second set of active antenna elements, during a second time period. Numerous other aspects are described.

Abstract: A method for managing beam alignment by a user equipment is provided. The method comprises receiving beam width information and base station location information from a base station, calculating a displacement of location of the UE based on location coordinates of the UE, measuring a change in a signal strength of the UE due to the displacement, and determining whether the UE is moving towards or away from the base station using at least one of the beam width information, base station location information, the displacement, and the measured change in the signal strength, determining whether a beam re-alignment is required based on the determination of the movement of UE, and transmitting a realignment request to the base station for a re-aligned beam width and a new transmission beam based on determining that the beam re-alignment is required.
