摘要： A method of direction finding (DF) positioning based on a simplified antenna platform format in a wireless communication network is proposed. A receiver receives antenna platform format information of a transmitter having multiple antenna elements. The antenna platform format information comprises an antenna platform format indicator, antenna platform position and orientation information, a number of antenna elements, and switching delay, phase center, and polarization information for each antenna element. The receiver receives a plurality of direction finding sounding signals transmitted from the transmitter via the multiple antenna elements. The receiver performs a DF algorithm based on the plurality of DF sounding signals and the antenna platform format information and thereby estimating a DF solution. Finally, the receiver determines its own location information based on the estimated DF solution.

摘要： 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.

摘要： 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.

摘要： 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.
