An apparatus may comprise a memory configured to store a data structure with a set of modulation and coding schemes (MCS) available to an orthogonal frequency division multiplexing (OFDM) system, each MCS having an associated pilot dwell time. The apparatus may further comprise a processor circuit coupled to the memory, the processor circuit configured to identify a MCS to communicate a packet using multiple subcarriers of the OFDM system, and retrieve a pilot dwell time associated with the MCS from the memory, the pilot dwell time to indicate when to shift a pilot tone between subcarriers of the multiple subcarriers during communication of the packet. Other embodiments are described and claimed.

Abstract: Logic may comprise hardware and/or code to select a narrow band from a wider channel bandwidth. Logic of communications between devices may select, e.g., a 1 or 2 MHz sub-channel from a wider channel bandwidth such as 4, 8, and 16 MHz and transmit packets on the selected 1 or 2 MHz channel. For instance, a first device may comprise an access point and a second device may comprise a station such as a low power sensor or a meter that may, e.g., operate on battery power. Logic of the devices may facilitate a frequency selective transmission scheme. Logic of the access point may transmit sounding packets or control frames across the sub-channels of the wide bandwidth channel, facilitating selection by the stations of a sub-channel and subsequent communications on the sub-channel between the access point and the station.

Abstract: A platform to facilitate updating an equalizer in addition to other receiver functionality is disclosed. A transmitting entity transmits one or more pilot tones in each protocol data unit (PDU) such as a packet. A receiving entity is able to derive a sufficiently accurate channel response estimate with the pilot tones under most channel conditions. The method and apparatus rotates the pilot tones through each of the subcarriers over the packet. The pilot tones would be separated by some number of data subcarriers so that estimation of slope and intercept for subcarrier tracking could be maintained. As the pilot tones are swept across the subcarriers, the taps for the equalizer for the subcarriers for which the pilot tones currently populate would be updated as well. This approach allows the system to track channel changes over time.
Abstract translation: 公开了除了其它接收机功能之外还有助于更新均衡器的平台。 发送实体在诸如分组的每个协议数据单元（PDU）中发送一个或多个导频音调。 接收实体能够在大多数信道条件下使用导频音导出足够准确的信道响应估计。 该方法和装置通过分组上的每个子载波来旋转导频音。 导频音将被一些数量的子载波分开，从而可以维持用于子载波跟踪的斜率和截距的估计。 当导频音被跨越子载波扫描时，用于当前填充导频音的子载波的均衡器的抽头也将被更新。 这种方法允许系统跟踪频道随时间的变化。
