    Abstract: A method of joint position detection by a plurality of known location sensor devices is proposed in an indoor wireless local area network. A tag can query the sensors by sending a request. Timestamps of the query signal are recorded by the sensors. A known location designated sensor responds to the request and triggers a process to correct the clock offsets of other sensors. The timestamps are then corrected based on the clock offsets. The corrected timestamps are then sent to a position processor for determining the tag location.

    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。
