Abstract
- Bandwidth part (BWP) and discontinuous reception (DRX) are critical designs to help devices save power. Unlike DRX, a time-domain power-saving mechanism, the BWP is a frequency-domain mechanism newly proposed in the 3GPP NR system. The interaction between the two mechanisms needs investigation for performance optimization. Therefore, this work proposed a joint design for the BWP switching algorithm and analytical models. The simulation results showed that when the DRX cycle is 320 ms, and the packet arrival rate is 0.01/ms, our method improves 31.4% of packet delay or 19.5% of power consumption compared to the baselines. We also showed the range of the traffic arrival rate that a UE with both mechanisms configured is sensitive to the BWP switch strategy.
