Problems solved by technology
However, this method takes up more network resources, requires more baseband processing on the terminal side and generates a correspondingly larger power consumption
[0004] In other existing solutions, an antenna or induction device dedicated to radio frequency environment detection, as well as corresponding electrical tuning components, signal processing and control circuits, are added to the terminal, but these hardware structures are difficult to integrate with the chipset of the main communication system of the terminal, which is significantly Significantly increases the device, size and cost of the terminal

Embodiment Construction
[0034] As described in the background, the existing beam management method includes the terminal completing beam management in the network based on the RRC protocol, but this method not only occupies more network resources, but also generates relatively large power consumption on the terminal side. The existing beam management method also includes adding an antenna or sensing device dedicated to radio frequency environment detection in the terminal, as well as corresponding electrical tuning components, signal processing and control circuits, but this method increases the difficulty of hardware structure integration and increases The volume and cost of the terminal are reduced.
[0035]The inventor found through research that the most common shielding of the terminal in practical applications comes from other devices and casings near the installation of the antenna radio frequency module, hand-held and other human body shielding, other objects near the terminal that reflect or ...

The invention provides an antenna module selection method and device. The method is applied to a terminal device at least comprising a first AiP and a second AiP. The method comprises: a ULA array ina first AiP detecting signals emitted by a corresponding UPA array in the first AiP, comparing detected characteristic parameter values with a preset first set of characteristic parameter values, andobtaining a first comparison result; the ULA array in the second AiP detecting a signal transmitted by the corresponding UPA array in the second AiP, and comparing the detected characteristic parameter value with a preset second group of characteristic parameter values to obtain a second comparison result; and determining to use the first AiP or the second AiP for signal transceiving based on thecomparison result; and comparing the actual beam conditions detected by the plurality of AiPs with a preset characteristic parameter value, and selecting the AiP closest to the optimal beam configuration to perform signal transceiving, thereby realizing local detection and management of the beam by the terminal without adding extra hardware, saving network resources, and reducing the cost and power consumption of the terminal.
Description
technical field [0001] The present invention relates to the communication field, in particular to a method and device for selecting an antenna module, a terminal device, and a computer-readable storage medium. Background technique [0002] The 5G millimeter wave mobile communication system uses array antenna and beamforming technology, and the 5G terminal millimeter wave chip uses Antenna-in-package (AiP) technology, which has significant direction selectivity. Fast and accurate beam alignment and tracking at the transceiver end is an important technology for mmWave communication. Due to the fast attenuation of the signal in the millimeter wave frequency band, poor scattering and diffraction characteristics, and easy to be blocked, the signal energy can be concentrated through the narrow beam, and the beam direction can be dynamically tracked and adjusted through beam management, so as to better support the millimeter wave frequency channel. Rapid change characteristics. ...
