Abstract: This application discloses positioning methods and communication apparatuses, and relates to the field of communication technologies. In one example, a method applied to a positioning terminal includes receiving a first message from a network device, wherein the first message comprises clock synchronization information and access network resource allocation information; sending access request information to the network device based on the first message; receiving positioning resource allocation information from the network device, wherein the positioning resource allocation information is determined after the network device receives the access request information sent by the positioning terminal and sends the access request information to a location management function (LMF); determining a positioning pulse based on the positioning resource allocation information; and sending the positioning pulse to one of three or more network devices in a range of a neighborhood of the positioning terminal.

Abstract: This application provides a communication apparatus. The communication apparatus includes at least one transmit antenna unit, at least one receive antenna unit, and a signal processing unit. The signal processing unit is configured to: control the at least one transmit antenna unit and the at least one receive antenna unit to communicate with at least one first terminal on a first frequency band; control at least one target transmit antenna unit to send a radar signal on a second frequency band; and control at least one target receive antenna unit to receive a first echo signal on the second frequency band. The at least one transmit antenna unit includes the at least one target transmit antenna unit. The at least one receive antenna unit includes the at least one target receive antenna unit. The first frequency band and the second frequency band do not overlap.

Abstract: This invention provides an orange-yellow-emitting phosphor, the preparation method and the use thereof. This orange-yellow-emitting phosphor has a general formula represented by formula I: Sr9?a?b?xMaMg1.5+b(PO4)7:xEu2+??formula I wherein in formula I, said M is one or two of Ca and Ba; and 0.001?x?0.9, 0?a?1.0, 0?b?2.3. This orange-yellow-emitting phosphor uses a phosphate as the host material and Eu2+ ions as activation ions. The chemical properties of the phosphor are stable. The phosphor has relatively wide excitation band and emission band. And the red component in its emission spectrum is abundant, therefore, coupling the blue InGaN chip with the orange-yellow-emitting phosphor provided by this invention can obtain warm white light. The phosphor is radiation free, therefore, it will not be harmful to the environment.
