In FBE, the transmitters can be focused to assist information with various prerequisites and have lower energy utilization. There are two plans to further develop the URLLC execution in FBE: The first scheme permits the transmitters to utilize various fixed frame period (FFP) configurations and the second scheme configures the FFP’s starting point of each transmitter depending on its need. In FBE, if a transmitter has a packet to send, it can only detect the channel and begin a transmission at the fixed time. The performance of the FBE channel access mechanism is dissected to see its effect on URLLC activity in unlicensed spectrum.
