AI Technical Summary
In the existing IEEE 802.11 WLAN standard, multiple resource units can only be allocated to different users, which leads to an increase in the overall error rate in interference scenarios, especially since noisy resource units cannot be effectively utilized.
By allocating multiple resource units to a single user in an alternating and proportional manner, high diversity is achieved using codes and constellation diagrams. This ensures that the number of bits is proportional to the number of segmented tones covered by the resource unit, and the bits are allocated alternately in an alternating cycle, combined with frequency domain and spatial domain mapping operations.
It reduces the overall error rate and improves the reliability and efficiency of the communication system, especially in noisy environments, by effectively utilizing multiple resource units.
