Abstract: Techniques are provided for radio frequency (RF) sensing using a single wireless device. An example method for determining a distance to an object with radio frequency sensing includes transmitting a radio frequency signal with a transmit channel on a wireless device, receiving a leakage signal with a receive channel on the wireless device at a first time, such that the leakage signal is based on the radio frequency signal, receiving a reflected signal with the receive channel on the wireless device at a second time, such that the reflected signal is based on the radio frequency signal reflecting from the object, and determining the distance to the object based at least in part on a difference between the first time and the second time.

Abstract: A method for generating a Physical Layer Convergence Protocol Packet Data Unit (PPDU) having a preamble and a payload for television white space transmission (TVWS) is provided. The symbols of the PPDU each include 128 total (orthogonal frequency-division multiplexing) OFDM tones or 256 total OFDM tones. The preamble includes a signal (SIG) field symbol having 108 OFDM data tones if the symbols of the PPDU include 128 total OFDM tones or having 234 OFDM data tones if the symbols of the PPDU include 256 total OFDM tones. The SIG field symbol indicates at least one of an amount of data in the payload or a length of time that the PPDU will occupy the television broadcast frequency spectrum. The PPDU is generated by down-clocking an 802.11ac signal by a factor so that the bandwidth of the PPDU decreases down to one appropriate for use in a TVWS channel.
Abstract translation: 提供了一种用于产生具有用于电视白空间传输（TVWS）的前同步码和有效载荷的物理层汇聚协议分组数据单元（PPDU）的方法。 PPDU的符号各自包括128个总共（正交频分复用）OFDM音调或256个总OFDM音调。 如果PPDU的符号包括128个总OFDM音调或具有234个OFDM数据音调，如果PPDU的符号包括256个总OFDM音调，则前导码包括具有108个OFDM数据音调的信号（SIG）字段符号。 SIG字段符号指示有效载荷中的数据量或PPDU将占用电视广播频谱的时间长度中的至少一个。 PPDU是通过将802.11ac信号衰减一个因子来产生的，使得PPDU的带宽减小到适合于在TVWS信道中使用的PPDU的带宽。

Abstract: In a downlink multi-user multiple input multiple output (DL MU-MIMO) system, channel state information (CSI) feedback duration may strongly affect media access control (MAC) efficiency. While a time domain compression may give a significant reduction in feedback duration, the time domain compression may have complexity issues at the station (STA). In particular, for time domain compression, a large complex matrix multiplication may be required at the client to estimate a cyclic prefix (CP) length impulse response, which best models the frequency response of the channel. Embodiments of the invention comprise a hybrid scheme that may reduce the above complexity while maintaining significant compression gains.
Abstract translation: 在下行链路多用户多输入多输出（DL MU-MIMO）系统中，信道状态信息（CSI）反馈持续时间可能强烈地影响媒体访问控制（MAC）效率。 虽然时域压缩可以显着减少反馈持续时间，但是时域压缩可能在站（STA）处具有复杂性问题。 特别地，对于时域压缩，在客户端可能需要大的复矩阵乘法来估计循环前缀（CP）长度脉冲响应，其对信道的频率响应进行最佳建模。 本发明的实施例包括可以在保持显着的压缩增益的同时降低上述复杂性的混合方案。

Abstract: An apparatus and method are disclosed for effectively and efficiently arbitrating concurrent usage between WLAN and Bluetooth access technologies for co-located wireless devices. A state level arbiter determines state and relevant parameters of a WLAN module and of a Bluetooth module of a wireless transceiver unit. The state level arbiter uses the state and relevant parameters to determine which access technology (WLAN or Bluetooth) or combination of the access technologies (WLAN or Bluetooth) will provide the best concurrent performance for wireless transmissions at a given time for specific Bluetooth states and WLAN states.
