Abstract: The present disclosure provides a communication method and apparatus. In an example, the communication method may include: transmitting a first radar transmit signal in a first frequency band by using a first transmit antenna array; receiving a first echo signal of the first radar transmit signal in the first frequency band by using a first receive antenna array, where the first echo signal includes an echo signal corresponding to at least one first terminal; and communicating with at least one second terminal in a second frequency band by using a second transmit antenna array and a second receive antenna array, where the first frequency band and the second frequency band do not overlap.

Abstract: A positioning method, a device, a system, a chip, and a storage medium are provided. A network device is externally connected to N antennas, the network device has N receive channels, and the N antennas are in a one-to-one correspondence with the N receive channels. The method includes: A network device receives, by using each of the N antennas, a positioning signal sent by a terminal device, determines TOA information and/or RSSI information of the positioning signal on each of the N receive channels, and sends the TOA information and/or the RSSI information of the positioning signal on each of the N receive channels to a service anchor. The service anchor is configured to position the terminal device based on the TOA information and/or the RSSI information.

Abstract: A VEGF inhibitor is used in preparation of a medicament for treating hypoxia-related diseases. The VEGF inhibitor can significantly inhibit VEGF stress expression caused by hypoxia by acting on a binding pathway of VEGF and a VEGF receptor, is used for treating hypoxia and other related diseases, can significantly improve the oxygenation index of a patient, and can alleviate the hypoxic state of lung and other organ tissues, having good therapeutic effects.
