Abstract: Data samples of a signal transmitted by a WWAN are captured during a first set of capture ticks for a first capture period defined by a plurality of contiguous ticks. The first set of capture ticks comprises a first subset of the plurality of contiguous ticks, and the capturing is done using a WLAN receive chain having a switchable LNA gain state. The capturing of data samples is repeated for at least one additional capture period defined by a plurality of contiguous ticks to capture data samples during at least one additional set of capture ticks comprising an additional subset of the plurality of contiguous ticks for which data samples were not previously captured. The LNA gain state of the WLAN receive chain is switched at least once over the plurality of capture periods. Gain state switching may occur a capture period, or between capture periods.

Abstract: A plurality of data samples are captured during a single capture period using a WLAN receive chain, wherein the data samples include a signal of interest periodically transmitted by a WWAN. A preferred LNA gain state is selected from among a plurality of available LNA gain states for the WLAN receive chain. The plurality of gain states may be a discrete set of LNA gain states or may be a set of LNA gain states derived from energy measurements. The LNA gain state of the WLAN receive chain is set to the selected LNA gain state and data samples are captured during each of a plurality of contiguous capture ticks within a capture period. The captured data samples are processed to detect for the signal of interest.

Abstract translation: 在单个捕获周期期间使用WLAN接收链捕获多个数据样本，其中数据样本包括由WWAN周期性发送的感兴趣的信号。 从用于WLAN接收链的多个可用LNA增益状态中选择优选的LNA增益状态。 多个增益状态可以是LNA增益状态的离散集合，或者可以是从能量测量导出的一组LNA增益状态。 将WLAN接收链的LNA增益状态设置为所选择的LNA增益状态，并且在捕获周期内的多个相邻捕获周期的每一个期间捕获数据样本。 捕获的数据样本被处理以检测感兴趣的信号。
