Abstract: Methods, systems, and devices for wireless communications are described. The method may include determining a parameter from a physical layer convergence protocol preamble of a management frame associated with one or more information elements, determining that the parameter associated with the one or more information elements is outside a range, and performing a low-power operation for at least a remaining portion of the management frame based on determining that the parameter associated with the one or more information elements is outside the range.

Abstract: The disclosure relates to minimizing power consumption of a WiFi system-on-chip (SOC) during idle periods. The disclosed architecture includes memory banks for the WiFi SoC's embedded processor that can be independently powered on/off and a Memory Management Unit (MMU) to translate virtual addresses to physical addresses and generate exceptions to process accesses to virtual addresses without a corresponding physical address. The architecture can implement a demand paging scheme whereby a MMU fault from an access to code/data not within the embedded memory causes the processor to fetch the code/data from an off-chip secondary memory. To minimize page faults, the architecture stores WiFi client code/data within the embedded processor's memory that is repeatedly accessed with a short periodicity or where there is an intolerance for delays of accessing the code/data.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include determining a signal strength indication from a field of a management frame associated with one or more information elements, comparing the signal strength indication to a first threshold and a second threshold, and performing a low-power operation for at least a remaining portion of the management frame based on determining that the signal strength indication is: greater than the second threshold, or less than the first threshold, or greater than the second threshold and less than the first threshold.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless device (e.g., an access point or a station) capable of supporting multiple chain configuration modes may monitor traffic on a wireless channel. The wireless device may, based on the monitoring, determine a series of values for a metric that is indicative of communication conditions. The metric may be a packet rate, channel congestion, or signal strength. The wireless device may dynamically select one of the supported chain configuration modes in which to operate based on the series of values for the metric. In some cases, the wireless device may compute a value for the metric based on the series of values and compare the value of the metric to a predetermined threshold. In such cases, selection of the chain configuration mode may be based on the results of the comparison. In some examples, one or metrics may be used.
