Abstract: In connection with an RF communication system, exemplary aspects involve a method for use in a communication system in which a first system (e.g., 802.11) that is asynchronously based and which is susceptible to interference from a second system (e.g., synchronous-based LTE-CV2X). Such interference is due to the frequency spectrum used by the first and second systems overlapping. To mitigate interference issues, example methods spreads out the times for messages in the first system, based on information concerning occupancy of the channel, and transmitting them relative to the end of a cycled transmission allocated for use by the second system.

Abstract: A battery pack comprises an enclosure; a plurality of network nodes that communicate with each other inside the enclosure and that generate a unique radio frequency (RF) signature; and a special-purpose computer processor that compares an incoming channel impulse response (CIR) of the unique radio frequency (RF) signature corresponding to an incoming packet to a plurality of stored valid RF CIR signatures and executes a resemblance metric to accept or reject the incoming packet.

Abstract: An apparatus for managing at least one battery comprises a wireless receiver apparatus that receives and processes an electromagnetic signal that includes at least one predefined power level of a packet transmitted to the wireless receiver apparatus; a power detector that determines an actual power level or a change in the actual power level of the transmitted packet received at the wireless receiver apparatus relative to the pre-defined power level; and a manual gain control processor that configures a gain of the wireless receiver apparatus according to the actual power level or the change in the actual power level.

Abstract: Aspects of the present disclosure are directed to communicating signals to receivers utilizing different protocols. As may be implemented in accordance with one or more embodiments, a set of signals are generated to include data configured in accordance with a first protocol and data configured in accordance with a second protocol. The set of signals are communicated over the wireless channel, by using the data corresponding to the first protocol for communicating with receivers operating in accordance with the first protocol and using the data corresponding to the second protocol to communicate with receivers operating in accordance with the second protocol.

Abstract: Aspects of the present disclosure are directed toward effecting communications in a manner that suppresses side-channel communications that may otherwise cause interference. As may be implemented in a manner consistent with one or more aspects characterized herein, an apparatus and/or method involve transmitting enhanced signals for in-band transmissions over a first one of a plurality of wireless communications channels shared by a plurality of stations for communicating wireless station-to-station communications. While transmitting the enhanced signals, communications by legacy devices on a second one of the wireless communications channels adjacent the first channel are suppressed by generating and transmitting a side channel interference signal on the second channel, therein causing legacy devices receiving the enhanced signals to withhold communications on the second channel.
