Embodiment Construction

[0092] This application can be applied in Figure 1a example application scenarios. In the following embodiments of the present application, the terminal and the base station send and receive data according to time sequence, where the time sequence unit can be a slot (time slot) or subframe, and the time sequence is a plurality of time sequence units arranged in sequence. The sequence unit number can be represented by natural numbers: 1, 2, ..., K, ... K+1. The timing unit number can also be represented by the traditional 5G cycle numbering method, that is, the cycle number includes three levels: system frame, subframe, and time slot. Each system frame is 10ms, and the number range of the system frame is 0 to 1024. One system frame It contains 10 subframes, and the number range of the subframe is 0-9. The number of time slots included in a subframe depends on the subcarrier spacing, as shown in Table 1. Assuming that the subcarrier spacing is 120KHz, the number range of the ti...

Abstract

According to the signal sending and processing method and device, and the terminal provided by the invention, the uplink receiving delay time is obtained, the starting time of sending the uplink time sequence unit X is calculated according to the uplink receiving delay time and the starting time of the downlink time sequence unit X under the condition that the downlink time sequence unit X is received, and at the starting time of sending the uplink time sequence unit X, the uplink time sequence unit X is sent, the uplink receiving delay time delay is Z times of the length of the time sequence unit, after the base station sends the downlink time sequence unit X, the uplink receiving delay time delay is delayed, the uplink time sequence unit X is received, and the initial positions of the uplink time sequence unit and the downlink time sequence unit are aligned on the base station side.

Description

[0001] This application is a divisional application with an application date of March 11, 2020, an application number of 202010165824.X, and an invention titled "a signal transmission and processing method and device". technical field [0002] The present application relates to the field of electronic information, and in particular to a signal sending and processing method and device. Background technique [0003] Figure 1a A satellite communication system is exemplified, including a terminal 101 , a base station 102 , and a satellite 103 . Among them, the satellite is used for the communication transfer between the terminal and the base station, that is, in the uplink communication (such as Figure 1a solid arrow), the terminal sends uplink data to the satellite, and then sends the uplink data to the base station after being relayed. In downlink communication (such as Figure 1a Dotted arrow), the base station sends downlink data to the satellite, and then sends the downli...
