    Abstract: Techniques for windowing a transmission are disclosed herein. In one aspect of the disclosure, the length of a window used for windowing may be configurable and determined for a transmission based on a configuration of the transmission. The configuration of the transmission may be determined based on one or more parameters such as a system bandwidth, a bandwidth assigned for the transmission, the location of the assigned bandwidth within the system bandwidth, a modulation type used for the transmission, etc. In another aspect of the disclosure, a preferred length for a window may be determined for each of a number of possible configurations of a transmission. Different possible window lengths may be evaluated for each possible configuration based on one or more performance metrics. For each configuration, a window length that can provide the best performance for that configuration may be selected as a preferred window length for that configuration.

    Abstract: Certain aspects of the present disclosure provide a dual antenna distributed radio frequency front end (RFFE). RFFE topologies described herein may provide lower insertion loss (IL), reduced emission mask, decreased power consumption, and/or lower noise figure (NF) compared to conventional RFFE topologies. One example apparatus for wireless communications generally includes first and second power amplifiers (PAs) for amplifying signals for transmission, a transmit antenna for transmitting the amplified signals, a receive antenna for receiving other signals to be processed in a receive path, and a first transmit filter configured to filter the amplified signals from the first PA before amplification by the second PA. For certain aspects, a divided inter-stage filter providing overlapping frequency bands may be utilized. For certain aspects, the RFFE may support frequency-division duplexing (FDD)/TDD (time-division duplexing) coexistence, including support for FDD/TDD MIMO (multiple input multiple output).

    Abstract: A BT receiver RF front end receives RF energy in a sequence of BT scan windows. Throughout a scan window, the front end is tuned to one hop frequency. Before and after the window the front end is in a disabled state. A WLAN energy detector processes an output of the front end during the window and determines whether more than a predetermined amount of RF energy was received onto the front end during the window. A BT baseband processor attempts to demodulate the output of the front end. If the WLAN energy detector determines that the predetermined amount of RF energy was received and if a BT signal could not be demodulated, then a WLAN wake-up signal is asserted, thereby causing a WLAN transceiver to be powered up to receive WLAN signals. BT scan intervals are varied in duration to facilitate a BT scan window overlapping a WLAN beacon.

    Abstract translation: BT接收机RF前端以BT扫描窗口的顺序接收RF能量。 在整个扫描窗口中，前端被调谐到一跳频率。 在窗口前后是前端处于禁用状态。 WLAN能量检测器在窗口期间处理前端的输出，并且确定在窗口期间是否在前端接收到超过预定量的RF能量。 BT基带处理器尝试解调前端的输出。 如果WLAN能量检测器确定接收到预定量的RF能量，并且如果BT信号不能被解调，则WLAN唤醒信号被断言，从而使WLAN收发器上电以接收WLAN信号。 BT扫描间隔在持续时间内变化以便于BT扫描窗口与WLAN信标重叠。
