Abstract
Embodiments of the present disclosure provide a transmission signal compensation method, a network side device and a terminal. The method includes: obtaining, by a network side device, a reference compensation parameter of a reference transmission link of a terminal; determining, by the network side device, a first compensation parameter of a first transmission link according to the reference compensation parameter, wherein the first transmission link is a transmission link between the terminal and a first satellite; performing, by the network side device, sending or receiving compensation on a transmission signal of the first transmission link according to the first compensation parameter.
Claims9
A transmission signal compensation method, comprising:
- obtaining, by a terminal, a first compensation parameter of a first transmission link, wherein the first transmission link is a transmission link between the terminal and a first satellite, the first compensation parameter of the first transmission link is determined according to a reference compensation parameter of a reference transmission link of the terminal, and the reference compensation parameter is a compensation parameter used to compensate for at least one of transmission delay and frequency offset of a transmission signal of the terminal in the reference transmission link, the compensation parameter comprises timing advance and a Doppler frequency shift compensation value, the timing advance is configured to compensate for the transmission delay and the Doppler frequency shift compensation value is configured to compensate for the frequency offset, the reference transmission link is a transmission link between the terminal and a second satellite or the reference transmission link is a transmission link between the terminal and a ground base station;
- performing, by the terminal, sending or receiving compensation on a transmission signal of the first transmission link according to the first compensation parameter.
A terminal comprising:
- a transceiver, a memory, a processor, and a program stored on the memory and executed by the processor, wherein,
- the transceiver or the processor is configured to obtain a first compensation parameter of a first transmission link, wherein the first transmission link is a transmission link between the terminal and a first satellite, the first compensation parameter of the first transmission link is determined according to a reference compensation parameter of a reference transmission link of the terminal, and the reference compensation parameter is a compensation parameter used to compensate for at least one of transmission delay and frequency offset of a transmission signal of the terminal in the reference transmission link, the compensation parameter comprises timing advance and a Doppler frequency shift compensation value, the timing advance is configured to compensate for the transmission delay and the Doppler frequency shift compensation value is configured to compensate for the frequency offset, the reference transmission link is a transmission link between the terminal and a second satellite or the reference transmission link is a transmission link between the terminal and a ground base station;
- the transceiver or the processor is configured to perform sending or receiving compensation on a transmission signal of the first transmission link according to the first compensation parameter.
