TL;DR: The network throughput of the proposed group-based UORA is higher than that of the original U ORA in IEEE 802.11ax, so it has great practical significance.

TL;DR: Aiming at the problems of low efficiency of buffer information collection and sharp drop of system throughput caused by the aggravation of conflicts in the multi basic service set (BSS) high density deployment overlap coverage scenario of next generation wireless local access network (WLAN), an access point cooperation based multi-BSS multi-user full duplex multiple access protocol named as CMMFD is proposed.

TL;DR: A QoS-oriented OFDMA MAC for the next generation WLAN to support future wireless traffic feature which is QoS of diversification and high requirements and through the simulation, the system effective throughput is 57.8% and 59% higher than the OFD MA MAC of the sequential scheduling algorithm and the of the proportional fairness algorithm.

TL;DR: An orthogonal frequency division multiple access (OFDMA) based neighbor discover and tracking protocol for directional ad-hoc network and the neighboring state partitioning method based on discovery time and multiple resource unit access and frame format design based on OFDMA is proposed.

TL;DR: A spatial clustering group-based OFDMA protocol (SCG-OFDMA), designed based on the 802.11ax Multi-User (MU) MAC framework, that can reduce the degree of interference diffusion and enhance the area throughput in high-density deployment scenarios.
