Title:
RANDOM ACCESS DEVICE AND METHOD BASED ON SUCCESSIVE INTERFERENCE CANCELLATION
Document Type and Number:
WIPO Patent Application WO/2022/014912
Kind Code:
A1
Abstract:
The random access device based on successive interference cancellation, according to the present invention, comprises: a communication unit which transmits and receives a packet to and from at least one user terminal; and a control unit which estimates the number of backlog users according to the status of a time slot in which a packet is received via the communication unit, calculates transmission probabilities according to the number of backlog users, and controls the communication unit to transmit the transmission probabilities to said at least one user terminal.
