Abstract: A method of STA-initiated uplink (UL) aggregation is proposed in a wireless communication system. Under the STA-initiated UL aggregation, an STA can gain access to the medium through contention and after winning the TXOP, it passes the TXOP ownership to its AP to allow it to trigger UL MU transmission. Thus, the AP has increased chance of utilizing the medium while maintains fairness to both legacy APs and STAs. In addition, once AP takes over ownership of the TXOP, if it detects idle secondary channels, it can enable UL aggregation over the idle secondary channels, thereby fully utilizing the entire system bandwidth.

Abstract: A method of sub-channel independent network allocation vector (NAV) management by a wireless station (STA) in a wideband wireless communications system is proposed. In the wideband system having multiple sub-bands, each NAV for a corresponding sub-band is independently managed. The protection duration for each NAV is independent for each sub-band and the threshold or update rule for NAV modification is also independent for each sub-band. The threshold or update rule for NAV modification may also be different when the NAV is generated or propagated by an OBSS STA. Furthermore, early termination of NAV is allowed if the NAV is set by an OBSS STA only.

Abstract: A method of performing OFDMA transmission with aggregation from multiple access categories to improve channel utilization of a wireless channel is proposed. In one novel aspect, data from multiple access categories are allowed to be aggregated and transmitted in the same packet to utilize idle time efficiently. In downlink OFDMA, AP can send different AC data to different STAs so that AP can better arrange the transmission resource block. If the resource for one STA has long enough idle time, AP can aggregate more data that is different to the current AC for the same STA to better utilize the resource. In UL OFDMA, different STAs can send different AC data to AP. If the resource for one STA has long enough idle time, the STA can aggregate more data that is different to the current AC to better utilize the resource.

Abstract: A method of mitigating inter-BSS interference via synchronized inter-BSS operation is proposed. By aligning the transmission of UL and DL transmission in two overlapping OBSSs, the inter-BSS STA-to-STA and inter-BSS AP-to-AP types of interference can be eliminated. Furthermore, based on the BSS overlapping geometry and the STA location, different interference mitigation schemes can be applied to mitigate inter-BSS AP-to-STA and inter-BSS STA-to-AP types of interference.
