摘要： A method for determining a communication path of millimeter wave signal and measurement device using the method includes a first measuring device and a second measuring device. The first measurement device queries a list to determine a first AOD of the first measurement device corresponding to a LOS, and controls the array antenna of the first measurement device to send the millimeter wave signal at the first AOD of the first measurement device corresponding to the LOS to the second measurement device. The second measurement device queries the list to determine a first AOA of the second measurement device corresponding to the LOS, and controls the array antenna of the second measurement device to receive the millimeter wave signal at the first AOA of the first measurement device corresponding to the LOS. Thus, a downlink between the first measurement device and the second measurement device can be quickly established.

摘要： An envelope tracking device includes a fine slot peak tracking (FSPT) circuit, at least one power amplifier, and an envelope modulator. The FSPT circuit is connected to the power amplifier through the envelope modulator. The FSPT circuit generates envelope signals based on input signals, adds an offset to the envelope signals, and expands and smoothes the added envelope signals. The envelope modulator generates envelope voltage signals according to the smoothed envelope signals, and outputs the signals to drain of the power amplifier. The envelope voltage signals are time-aligned with the amplified signals which are transmitted to gate of the power amplifier.

摘要： An antenna structure includes a first array antenna having a number of first antenna units. The antenna units are arranged along a first direction and a second direction. The first antenna units are monopole antennas. The monopole antennas include a radiating body having a strip portion and a bulb portion. The radiating body generates radiation along the first direction or the second direction. The strip portion is electrically coupled to a signal source. The bulb portion is electrically coupled to the strip portion. An end of the bulb portion away from the strip portion is semi-circular in shape.

摘要： A measurement method for measuring millimeter wave (mm-wave) signal and device using the method includes a first measuring device receiving a mm-wave signal by an array antenna at a first angle of arrival corresponding to a position of the first measuring device, the mm-wave signal being sent by a second measuring device at a first angle of departure. Thereby, a downlink between the first measuring device and the second measuring device can be established quickly. From a certain ascertainable location, the first measurement device sends the mm-wave signal by the array antenna at a second angle of departure, and the second measurement device receives the mm-wave signal at a second angle of arrival corresponding to the position of the first measuring device, thus, an uplink between the first measuring device and the second measuring device can be established quickly.

摘要： A heterogeneous network includes a first base station, a number of second base stations and a mobile device. The mobile device communicates with the second base stations via mm-wave signals and send, via wireless signals, the first base station a position of the mobile device and a request for connecting with one of the second base stations. The first base station determines one of the second base stations to connect with the mobile device according to the position and the request sent by the mobile device. The first base station sends, via the wireless signals, the mobile device a first beam angle information and triggers the mobile device and the one determined second base station to perform a beam training process according to the first beam angle information.
