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.

Abstract: A method of fast link adaptation for Bluetooth long-range wireless networks is provided. A novel rate indication (RI) field is incorporated in a data packet to enable auto detection of rate adaptation at the receiver side. The data packet comprises a preamble, a first packet portion including the RI field, and a second packet portion including the PDU. The first packet portion is encoded with a first rate while the second packet portion is encoded with a second rate indicated by the RI field. The transmitting device raise/lower the encoding rate when the link quality is good/poor. The receiving device can provide recommended rate or link quality feedback information via an LMP message to help the transmitting device making rate adaptation decision. The transmitter can unilaterally decide the data rate for the second packet portion without receiver recommendation.

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 translation: 在无线通信系统中提出了STA发起的上行链路（UL）聚合的方法。 在STA发起的UL聚合下，STA可以通过竞争获得对媒体的访问，并且在获得TXOP之后，它将TXOP所有权传递给其AP，以允许其触发UL MU传输。 因此，AP在传统AP和STA保持公平的同时增加了利用介质的机会。 此外，一旦AP接管TXOP的所有权，如果它检测到空闲次要信道，则它可以在空闲次信道上启用UL聚合，从而充分利用整个系统带宽。

Abstract: A method of fast link adaptation for Bluetooth long-range wireless networks is provided. A data packet comprises a preamble, a first packet portion including a rate indication field, and a second packet portion including a PDU. The first packet portion is encoded using a first modulation and coding scheme with a first rate while the second packet portion is encoded using a second modulation and coding scheme with a second rate indicated by the RI field. A transmitter thus can use different MCS options to support variable data rates by adapting to channel conditions, and then uses the novel RI field to indicate the data rate to a receiver dynamically. As a result, fast link adaptation can be achieved for different applications with different rate requirements, to provide higher data rate, reduce connection time, lower power consumption, and improve link quality.
