The patent for ” Method and Device for Satellite Communication ” applied by Huawei Technologies Co., Ltd. had been authorized. The patent abstract shows that the method can reduce the energy consumption and communication complexity of terminal equipment on the premise of improving communication performance.
The present application provides a method and device for satellite communication, the method comprises: The terminal device receives first indication information, where the first indication information is used to indicate a valid period of the first parameter information, and the first parameter information includes at least one of the following information: a first timing advance, parameter information.
The first frequency offset pre-compensation or the parameter information of the first frequency offset pre-compensation; the terminal device performs uplink communication with the satellite according to the first parameter information during the valid period, and the terminal device receives the first indication information, which can know the effective period of parameter information such as the first timing advance.
The parameter information of the first timing advance, the first frequency offset pre-compensation, or the parameter information of the first frequency offset pre-compensation. Monitor whether the parameter information is updated within the valid period so that the energy consumption and communication complexity of the terminal device can be reduced on the premise of improving communication performance.
In addition, Huawei has previously applied for a number of patents related to satellite communications, such as “satellite network routing methods, devices, equipment, systems, and readable storage media” patents, which can reduce the distance of inter-satellite link information transmission, save communication overhead, and improve the inter-satellite routing capability in the space-earth integrated network communication scenario.
The patents for “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. Ming-Chi Kuo previously broke the news that Huawei’s new Mate 50 / Pro series, which will be released on September 6, may provide emergency SMS services through satellite communications supported by the Beidou system.
