AI Technical Summary
In existing technologies, when using multi-timeslot access schemes to solve the pilot conflict problem in user equipment selection, it can lead to a reduction in the timeliness of data transmission by user equipment.
Based on the timeliness and reliability requirements of the service type, the devices to be accessed are classified into levels, and the level group of each device to be accessed is determined. The request information sent by each device based on the preset codebook and level group is received in sequence, decoded, and the decoding result is fed back. The capacity of satellite access devices is expanded by using the preset codebook, which alleviates the pilot conflict selected by users.
It improves the timeliness and reliability of data transmission by the devices to be connected, meets the timeliness and reliability requirements of different service types, and expands the capacity of satellite access devices.
