  • Publication number: 20230283362
    Abstract: Example beam hopping methods and apparatus are described. In one example method, a first satellite sends a communication signal to a first area by using a first beam, where the communication signal is used by the first satellite to communicate with a terminal device in the first area, and the first area belongs to an area covered by the first satellite. The first satellite sends a positioning signal to a second area by using a second beam, where the positioning signal is used by a terminal device in the second area for positioning measurement.

  • Patent number: 11616567
    Abstract: A satellite communication method and a network device are disclosed. A first network device learns of traffics of a plurality of satellite communications link or air interface resources allocated to a plurality of satellite base stations. The first network device sends identification information to a second network device, where the identification information indicates that a traffic of a satellite communications link reaches a specified threshold, or that an air interface resource allocated by a ground station to a satellite base station reaches a specified threshold. The second network device receives an identifier message, determines a to-be-linked satellite base station that has an idle resource, and sends, to the to-be-linked satellite base station, a second message including information about a generated beam of the to-be-linked satellite base station.

  • Publication number: 20230047970
    Abstract: Embodiments of this disclosure provide a power adjustment method, apparatus, and system. A first access network device may obtain a power back-off value at a first moment, and compare the power back-off value at the first moment with a power back-off value at a second moment. The second moment is earlier than the first moment. When a difference between the power back-off value at the second moment and the power back-off value at the first moment is greater than or equal to a first threshold, the first access network device adjusts an output power based on the power back-off value at the first moment.

  • Publication number: 20220225208
    Abstract: Example neighboring cell relationship configuration methods and apparatus are described. One example method includes: generating a neighboring cell status function identifier by a satellite, where the neighboring cell status function identifier can be used to indicate an inactive state of at least one neighboring cell of a satellite cell. The satellite sends neighboring cell relationship configuration information that includes the neighboring cell status function identifier to a communications device, and the communications device determines a configuration status of a corresponding neighboring cell based on the neighboring cell relationship configuration information.

  • Publication number: 20220190965
    Abstract: A media access control element (MAC CE) indicates a terminal device to enable or disable at least one hybrid automatic repeat request (HARQ) process, or the MAC CE requests a network device to enable or disable the at least one HARQ process. This provides a solution for dynamically controlling a HARQ function.

  • Publication number: 20210410161
    Abstract: According to a scheduling method and apparatus in a communication system, and a storage medium, a communication device obtains system status information, where the system status information includes network status information; obtains a scheduling policy based on the system status information and a deep neural network; and performs communication according to the scheduling policy. The deep neural network is obtained through training based on historical system status information, and the historical system status information includes system status information in all scheduling periods before a current scheduling period. Therefore, the scheduling policy obtained based on the deep neural network can meet a balancing requirement of throughput and fairness and solves a problem of low performance of an existing communication system.
