Abstract
Provided are a method for wireless communication, a terminal device, and a network device. One example method includes: receiving a first handover command indicates a terminal device to perform a handover from a first satellite to a second satellite; and detecting a first synchronization signal and a second synchronization signal within a first resource domain and a second resource domain, respectively; wherein the first resource domain and the second resource domain are determined based on first information, the first synchronization signal is associated with the first satellite, and the second synchronization signal is associated with the second satellite.
Claims20
A method for wireless communication, comprising:
- receiving, by a terminal device, a first message that indicates the terminal device to perform a handover from a first satellite to a second satellite;
- detecting, by the terminal device, a first synchronization signal and a second synchronization signal within a first resource domain and a second resource domain, respectively, wherein the first resource domain and the second resource domain are determined based on first information, the first synchronization signal is associated with the first satellite, and the second synchronization signal is associated with the second satellite, and wherein the first message further includes a first time point at which the first satellite ceases services for the terminal device and a second time point at which the terminal device initiates synchronization with the second satellite, the second time point precedes the first time point;
- and
- performing, by the terminal device, the handover from the first satellite to the second satellite within a time interval between the second time point and the first time point.
A method for wireless communication, comprising:
- sending, by a network device, a first message to a terminal device, wherein the first message indicates the terminal device to perform a handover from a first satellite to a second satellite;
- wherein a second synchronization signal is associated with the second satellite, a first synchronization signal is associated with the first satellite, a first resource domain and a second resource domain are configured for the terminal device to detect the first synchronization signal and the second synchronization signal, respectively, and the first resource domain and the second resource domain are determined based on first information, and wherein the first message further includes a first time point at which the first satellite ceases services for the terminal device and a second time point at which the terminal device initiates synchronization with the second satellite, the second time point precedes the first time point, and wherein a time interval between the second time point and the first time point is a time interval for performing the handover from the first satellite to the second satellite.
An apparatus, comprising:
- at least one processor;
- and
- one or more non-transitory computer-readable storage media coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions, when executed, cause the apparatus to perform operations comprising:
- receiving a first message that indicates a terminal device to perform a handover from a first satellite to a second satellite;
- detecting a first synchronization signal and a second synchronization signal within a first resource domain and a second resource domain, respectively, wherein the first resource domain and the second resource domain are determined based on first information, the first synchronization signal is associated with the first satellite, and the second synchronization signal is associated with the second satellite, and wherein the first message further includes a first time point at which the first satellite ceases services for the apparatus and a second time point at which the apparatus initiates synchronization with the second satellite, the second time point precedes the first time point;
- and
- performing the handover from the first satellite to the second satellite within a time interval between the second time point and the first time point.
