摘要

下一代Wi-Fi 7协议多链路非同步传输与接收模式下，多链路设备（MLD

multi-link device）在各个链路的传输结束时间需要对齐，可能需要进行数据填充（padding），从而导致频谱资源和能量的浪费。提出了一种MLD高能效传输算法，在满足数据传输时延限制的前提下，提高MLD站点（STA

station）总能效。所提算法分别从链路数据分发比例、通信资源与STA发送功率3个方面进行优化。仿真结果显示，所提算法在保证数据传输时延限制的前提下，通过减少padding数据降低能耗，使系统传输能效相较于基线方案提升约150%。

Abstract

In the multi-link non-simultaneous transmit and receive mode of next-generation Wi-Fi 7 protocol

the transmission ending time of multi-link device (MLD) needs to be aligned on each link

which may require data padding

resulting in the waste of spectrum resources and transmission energy consumption.A high energy efficient MLD transmission algorithm was proposed to improve the total energy efficiency of MLD station (STA) on the premise of meeting the data transmission delay limit.The proposed algorithm was optimized from the following three aspects: link data distribution ratio

communication resource allocation and STA transmission power.Simulation results show that the proposed algorithm can reduce energy consumption by reducing padding data on the premise of guaranteeing the delay limit of data transmission

and the transmission energy efficiency of the system is increased by about 150% compared with that of the baseline scheme.
