The resource allocation approach in NR very close LTE scheduling, but NR requires a higher level of precision, especially in its time domain scheduling within the physical layer.
The suggested architecture utilizes a cross-layer concept, incorporating information from different layers to guide scheduling decisions, as illustrated in Figure. This approach divides the scheduling process into three stages: the Traffic Differentiator, the TD Scheduler, and the FD Scheduler, which in the scheduling of Time Domain (TD) and Frequency Domain (FD) operations, respectively. |
