Shulou(Shulou.com)11/24 Report--

CTOnews.com September 2 news, Huawei Mate 50 series and full scene new product autumn conference will be held on September 6, today Huawei Yu Chengdong preheating said, The aircraft will be equipped with "Upward piercing sky" communication technology, According to the previous disclosure for satellite communication.

CTOnews.com found that on August 26, Huawei Technologies Co., Ltd. applied for a patent for "methods and devices for satellite communications" that had been granted. The patent abstract shows that this method can reduce the energy consumption and communication complexity of terminal equipment on the premise of improving communication performance.

The present application provides a satellite communication method and apparatus, the method comprising:

receiving, by a terminal device, first indication information, wherein the first indication information is used to indicate a valid period of first parameter information, and the first parameter information comprises at least one of the following information: a first timing advance, parameter information of the first timing advance, a first frequency offset pre-compensation, or parameter information of the first frequency offset pre-compensation; the terminal device performs uplink communication with the satellite according to the first parameter information in the valid period, and the terminal device can acquire the valid period of parameter information such as the first timing advance, parameter information of the first timing advance, the first frequency offset precompensation, or the parameter information of the first frequency offset precompensation by receiving the first indication information, so that it is unnecessary to monitor whether the parameter information is updated in the valid period, so that the terminal device can acquire the valid period of parameter information such as the first timing advance, parameter information of the first timing advance, parameter information of the first frequency offset precompensation, and the like on the premise of improving communication performance Reduce energy consumption and communication complexity of terminal equipment.

In addition, Huawei has previously applied for several patents related to satellite communication, such as "satellite network routing method, device, equipment, system and readable storage medium" patent, which can reduce the distance of inter-satellite link information transmission, save communication overhead and improve inter-satellite routing capability in space-earth integrated network communication scenario; The patent of "A Method and Device for Wireless Communication" can reduce the indication overhead of parameters and improve accuracy by expressing satellite parameters as reference values and floating values.

CTOnews.com learned that Tianfeng International analyst Guo Mingji previously revealed that Huawei will launch the Mate 50 / Pro series new machine on September 6, which may provide emergency SMS service through satellite communication supported by Beidou system.
