Description

technical field [0001] One or more embodiments of this specification relate to the field of wireless communication technologies, and in particular, to an indoor beam search and tracking method, device, and electronic equipment. Background technique [0002] Because of its narrow beam and wide frequency band, millimeter wave can effectively solve many problems faced by high-speed broadband wireless access, so it has broad application prospects in short-distance wireless communication. In millimeter wave communication, the antenna arrays of access points and mobile terminals are very small in size and can achieve sharp directional beamforming. Combined with the ultra-large bandwidth of millimeter wave, a large data transmission rate can be achieved. [0003] However, because mmWave has a narrow beamwidth, a small obstacle, such as a person's arm, can effectively disrupt the link. Therefore, in order to solve the link interruption problem caused by occlusion in the millimeter ...
