Abstract: Methods, systems, and devices for wireless communications are described. For example, a transmitting wireless device, such as a user equipment or a base station, may apply a first set of digital pre-distortion (DPD) coefficients to a plurality of antenna elements to form a first transmit beam. The wireless device may determine to switch from using the first transmit beam to using a second transmit beam that is different from the first transmit beam and may apply a second set of DPD coefficients to the plurality of antenna elements to form the second transmit beam, where the second set of DPD coefficients is different from the first set of DPD coefficients. The wireless device may transmit signaling using the second transmit beam based at least in part on applying the second set of DPD coefficients.

Abstract: The present invention provides a battery module system including a plurality of battery modules in a series electrical connection through a specified sequence, each battery module having a male connector and a female connector, the female connector of each battery module in electrical engagement into the male connector of an adjacent battery module, wherein the male connector and female connector are positioned along the sidewall of each battery module and have insulating structures that protect handlers of the battery modules from high voltage electrocution. The present invention also provides a battery module system in which the male and female connectors are attached to a top surface of each battery module.
