A terrestrial high frequency data communication system and method for implementing a pointing algorithm for endpoint nodes are described. The system includes an aggregation node and one or more endpoint nodes. In one example, a pointing direction for an endpoint node is determined based on a number of packet error rate (PER) measurements associated with a high frequency data communication link between the endpoint node and an aggregation node. Preferably, the endpoint node includes a steerable antenna module that includes one or more antennas. The steerable antenna module is configured to receive an azimuth value and an elevation value determined based on PER measurements associated with the high frequency data communication link, and to steer its one or more antennas based on the azimuth value and the elevation value to point to the aggregation node.

An electronic device and an antenna switching method of an electronic device are provided. A wireless signal is transmitted or received through a first antenna module among a plurality of antenna modules. A temperature of the first antenna module is measured through a first temperature sensor contained in the first antenna module among a plurality of temperature sensors. A second antenna module among the plurality of antenna modules is switched to based on the measured temperature of the first antenna module exceeding a predetermined value. Each temperature sensor is contained in each of the plurality of antenna modules. The wireless signal is transmitted or received through the second antenna module.

An electronic device includes a communication circuit, a plurality of antennas that are fed with power from the communication circuit, and a processor that controls the communication circuit. The processor is configured to receive a first signal for indicating initiation of configuration for carrier aggregation. The processor is also configured to change the configuration of at least one of the antennas or the communication circuit to perform the carrier aggregation if a second signal for indicating operation initiation of the carrier aggregation is received from a base station.

A directable antenna system includes at least one directable antenna which has an omnidirectional antenna at a center, an inner frequency selective surface centered around the omnidirectional antenna, and an outer frequency selective surface spaced from the inner frequency selective surface. An antenna control unit can vary antenna beamwidth by changing states of active elements of the inner and the outer frequency selective surfaces. The system may include a searchable database, for example, to direct the antenna in the optimum direction for transmission and reception at a particular location. Transmission and/or reception data from a second directable antenna can be used to aim the first directable antenna.

An arrival rate estimation device includes an average received power calculation unit that calculates an average received power for each mesh that constitutes an area, with respect to each of a plurality of base stations and each of a plurality of antennas included in each of the base stations and an arrival rate estimation unit that calculates a communication arrival rate by substituting the average received power into a cumulative distribution function of an instantaneous received power value, and based on the calculated communication arrival rate, calculates a communication arrival rate while giving consideration to a site diversity effect and an antenna diversity effect, the cumulative distribution function being obtained from a probability density function of an amplitude that instantaneously changes due to Rayleigh fading.

Concepts and technologies disclosed herein are directed to millimeter wave (“mmWave”) idle channel optimization. According to one aspect disclosed herein, an antenna system can include an antenna array that is configured in a first antenna configuration. The antenna system can generate and send downlink beams directed towards a network edge. A beam index scanner operating at the network edge can scan the downlink beams to determine beam index scanner data for the first antenna configuration. The beam index scanner can send the bream index scanner data to an antenna technician device. The beam index scanner data can indicate that a downlink channel provided by the downlink beams is not optimized. The antenna system can configure the antenna array in a new antenna configuration in an attempt to optimize the downlink channel provided by the downlink beams.

Methods, systems, and devices for wireless communication are described. A multi-antenna user equipment (UE) may communicate with a base station using a first antenna, determine to switch from the first antenna to a second antenna for communicating with the base station, determine a silence window in which communication with the base station is suspended, schedule the switch from the first antenna to the second antenna to occur during the silence window, and switch from the first antenna to the second antenna during the silence window.

An electronic device is provided. The electronic device includes a housing, an antenna structure including a printed circuit board, a first sub antenna structure including first group antenna elements, a second sub antenna structure including second group antenna elements disposed in a first direction from the first sub antenna structure, a third sub antenna structure including third group antenna elements disposed in a second direction perpendicular to the first direction, and a fourth sub antenna structure including fourth group antenna elements disposed to form a two-dimensional array together with at least some antenna elements of the first group antenna elements, the second group antenna elements, or the third group antenna elements, and a communication circuit that transmits and/or receives a signal having a frequency between 3 GHz and 100 GHz by using at least a part of the first, the second, the third, or the fourth group antenna elements.

A circuit arrangement including one or more processors configured to: detect a presence of one or more human object proximities based on sensor data; identify one or more coverage sectors of one or more antenna arrays, operably coupled to the one or more processors, in response to the detected presence of the one or more human object proximities; determine whether radio waves within the one or more identified coverage sectors satisfy a transmit power criteria; select one or more candidate coverage sectors of the one or more antenna arrays based the one or more identified coverage sectors; and determine at least one radio link quality for the radio waves of the one or more candidate coverage sectors.

A user equipment, a method, and computer-readable media. The UE, which includes a transceiver with a plurality of antenna panels, is configured to determine a link quality of a serving antenna panel. If the link quality of the serving panel is below a quality threshold, resources are allocated from the serving antenna panel to another antenna panel during a sweeping period to identify one or more beams of a target antenna panel for resuming communications. Measurements for a set of beams of the other antenna panel are obtained, during the sweeping period, with the allocated resources. The other antenna panel can be determined to be the target antenna panel based on the obtained measurements. The UE can switch from the serving antenna panel to the target antenna panel, select the one or more beams based on the obtained measurements, and resume the communications on the selected one or more beams.
