Abstract

Based on the directional LBT mechanism in unlicensed frequency bands, a novel receiver-assisted LBT mechanism is proposed with an improved optimal receiver energy detection threshold. Aiming at the recovery problem of binary channel access decision variables, the method for solving the mixed integer 0-1 programming problem is improved, and the binary search algorithm is used to make the model dynamically adjust the recovery threshold of binary optimization variables and energy detection threshold. While ensuring the fairness of access opportunities between the NR-U system and the WiFi system under the unlicensed spectrum, the throughput and frequency reuse efficiency of the coexisting system can be improved.
