Problems solved by technology

[0009] However, the terminal capability reporting process in the existing LTE system cannot be directly applied to the satellite communication system, because the satellite communication system still cannot determine the maximum transmit power of the terminal based on the terminal capability information reported in the existing terminal capability reporting process, and Ideal downlink transmit power for terminals

Embodiment Construction

[0034] In the satellite communication system, there will be a variety of terminals with different data sending and receiving capabilities at the same time. For example, the maximum uplink transmission power of high-end terminals is relatively high and the receiving sensitivity is high; while the maximum uplink transmission power of low-end terminals is small and the receiving sensitivity is high. Therefore, the network side node obtains the relevant capability information of the terminal to help the network side adopt an appropriate scheduling strategy for data transmission between the satellite and the terminal.

[0035] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0036] refer to figure 2 As shown, in the embodiment of the present invention, in the satellite communication system, the overview process of reporting terminal capability information is as follows:

[0037] Step 200: The network...

Abstract

The invention relates to the field of communication and discloses a method and device for reporting terminal capability information. The method includes the steps that after a terminal receives terminal capability inquiry information sent by network side nodes in a satellite communication system, terminal capability information messages are returned to the network side nodes, therefore, the network side nodes directly or indirectly obtains transmitter performance parameters and receiver performance parameters of the terminal based on the terminal capability information messages, and the terminal is dispatched for data transmission according to the transmitter performance parameters and the receiver performance parameters. Therefore, the network side nodes can smoothly obtain the terminal capability information so that the network side nodes can perform reasonable dispatching on the terminal in the satellite communication system, while the resource utilization rate and uplink and downlink transmitting power are improved, a data transmission delay is shortened, and the overall performance of the satellite communication system is improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for reporting terminal capability information. Background technique [0002] In order to take advantage of the industrial advantages of the terrestrial mobile communication system, especially the LTE (Long Term Evolution, long-term evolution) / LTE-Advanced (Long Term Evolution-Advanced, long-term evolution upgrade) system, ITU (ITU) proposes -Advanced system designs the future 4th generation satellite mobile communication system, and requires the terminal to reuse the chip design of the ground terminal as much as possible. [0003] A significant difference between the satellite mobile communication system and the ground mobile communication system is that the distance between the satellite and the communication terminal is far greater than the distance between the ground base station and the communication terminal, which is not suitable for closed-loop feedbac...
