Abstract

In a wireless local area network (WLAN), when the contention is fierce, most of the frames are collided and backoff windows are doubled, resulting in a low channel efficiency. 802.11 be introduces multi-link opertaions (MLO) but faces nonsimultaneous transmit and receive (NSTR) problem which limits the prospects of multi-links. In this paper a new multi-link operation scheme is proposed. When a link is transmitting, antennas from the other link usually suffer huge inteference and can’t receive properly. In the proposed scheme the interfered antennas are switched to the transmitting link to monitor collisions. If collisions are detected, one of the colliders stops transmitting. Collisions are thus eliminated at the early stage. Simulation shows that using this scheme, the channel efficiency of a highly competitive network stays at a high level compared to traditional solutions. Simulation also shows that the proposed scheme offers better QoS.
