    Abstract: A system for determining a state of health (SOH) of an energy storage device comprises a controller configured to be coupled to the energy storage device. The controller is configured to determine a current value drawn by or supplied to the energy storage device over a predefined period of time. In response to the current value not satisfying a current threshold, the controller determines a current gain factor and determines an adjusted current value from the determined current value based on the current gain factor. The controller is configured to determine an estimated SOH of the energy storage device based on the adjusted current value, and indicate the estimated SOH on a user interface.

  • Publication number: 20210274545
    Abstract: Sidelink communication operations may be enhanced through the use of communications requirement signaling, which may include, for example, indications of the type, size, quality of service requirements, pending buffer sizes, and the like, and through the evaluation of such signaled information to determine whether existing grants and logical channels may suffice for new sidelink traffic. Grants may be requested via sidelink scheduling requests and sidelink buffer status reporting, for example, which allow scheduling devices, such as base stations and scheduling user equipment apparatuses, early insight into needs of sidelink traffic for application with divergent QoS requirements.

  • Publication number: 20210243628
    Abstract: Device, systems, and/or techniques for using sub-channel signaling information between an access point and a first station are disclosed. An uplink trigger sent from the access point to the first station may be received. A map may be transmitted from the first station indicating at least one sub-channel that is available for spatial sharing by a second station. The first station may receive an acknowledgement from the access point that data was transmitted from the second station on the at least one sub-channel and/or received by the at least one access point. An OFDMA transmission having a sub-channel/sub-band available for transmitting data may be determined. An energy in the sub-channel/sub-band may be measured and/or compared to a dynamic and/or static threshold. Whether a sub-channel/sub-band is free or busy may be determined for example based on if the measured energy is, or is not, greater than the threshold.
