Abstract: This application provides a multi-air-interface communication method and an apparatus. In the method, a mobile terminal supports a plurality of types of air interfaces. The method resolves a BSR sending problem, a PHR reporting problem, and a DRX problem in a case of a plurality of air interfaces. The method that resolves the BSR sending problem in the case of the plurality of air interfaces enables a base station to more accurately allocate a radio resource to the mobile terminal based on a BSR sent on each air interface by the mobile terminal. The method that resolves the PHR reporting problem in the case of the plurality of air interfaces enables the base station to more accurately allocate the radio resource to the mobile terminal. The method that resolves the DRX problem in the case of the plurality of air interfaces is more beneficial to power saving of the mobile terminal.

Abstract: Embodiments of the present disclosure relate to an environment perception method and a base station. The method includes: sending, by a base station, an electromagnetic perception signal to a to-be-perceived region; receiving electromagnetic feedback signals transmitted, scattered, and reflected from an ambient environment of the to-be-perceived region and an object in the to-be-perceived region; and calculating environment information of the to-be-perceived region based on the electromagnetic feedback signals and the electromagnetic perception signal. In this way, environment information of a coverage area of the base station can be determined. In addition, environment information update frequency may be dynamically adjusted by setting a detection period for sending an electromagnetic perception signal, so as to meet environment information detection requirements of different applications, for example, real-time detection on environment information and high resolution detection on environment information.
