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 spatial re-use with TPC and adaptive CCA is proposed. A spatial re-use station detects spatial re-use information associated with other peer OBSS stations. The spatial re-use information comprises a TX spectral density (power/Hz) and received signal or interference information of each inter-BSS peer station. The spatial re-use STA determines a TX spectral density based on the detected spatial re-use information. The spatial re-use STA then contends the medium for spatial re-use transmission opportunity (TXOP) with an intra-BSS peer station. Finally, the spatial re-use STA starts spatial re-use frame exchange with the intra-BSS peer station using the determined TX spectral density. By adjusting the TX spectral density, the spatial re-use STA adapts its CCA level to spatially reuse the medium without causing collision and interference to OBSS stations and thus increases network throughput.

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 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 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.

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 performing contention-based uplink OFDMA transmission is proposed in accordance with one novel aspect. A wireless communications station (an AP) reserves both dedicated resource and contention resource for uplink OFDMA operation for a list of communications devices (STAs). For contention-based random access, the AP does not need to collect traffic requests from the STAs. The AP only needs to make simple resource arrangement. The AP only needs to specify the allocated resource for random access and the uplink OFDMA operation duration and timing for each uplink OFDMA packet. Each STA having traffic request will contend the resource based on a random access probability scheme.

Finally, the receiver determines its own location information based on the estimated DF solution.

Abstract: Methods and apparatus are provided for clear channel assessment in the Wifi network. In one novel aspect, different clear channel assessment (CCA) threshold value is set for intra-BSS and inter-BSS frames during the counting down process. A CCA procedure senses the radio channel and determines if the radio channel is busy or idle during the backoff period by comparing the signal level value of detected fames with the CCA threshold value. The counting down will be suspended if the radio channel determined to be busy. If the detected frame is inter-BSS frame, the CCA threshold value is raised. If the signal level of the detected frames is lower than the inter-BSS CCA threshold for inter-BSS fames, the radio channel is considered idle. The counting down process is resumed.
