Abstract

The embodiment of the invention provides a mode switching method and device. The mode switching method includes the steps that a first changing speed of a signal arrival angle of a communication opposite end device on a mobile device is acquired, and the mobile device works in a directional transmission mode; the mobile device is switched to be in an omnidirectional transmission mode with the speed responding to the first changing speed higher than a first threshold value. The embodiment of the invention provides an antenna scheme of the mobile device.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a mode switching method and device. Background technique [0002] Currently, in the field of mobile communications, smart antennas are mostly deployed on the base station side. The necessary prerequisite for the smart antenna to realize directional transmission is to realize the estimation of the angle of arrival (AOA for short) of the received signal, and determine the direction from the main propagation path (main path for short) according to the estimated AOA, that is, The direction of arrival (Direction of Arrival, DOA for short) of the signal, this DOA is used as the expected transmission direction. [0003] Smart antennas can also be implemented on mobile devices. The benefits include at least: reducing the radiation of electromagnetic waves to the human body, reducing device power consumption, improving communication privacy, and increa...
