Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an apparatus may receive an indication of a selected digital pre-distortion (DPD) kernel from multiple DPD kernels. The apparatus may store multiple envelope values associated of with samples of an in-phase/quadrature (I/Q) signal and select a subset of envelope values based at least in part on the selected DPD kernel. The apparatus may generate, using the subset of envelope values and a look-up-table (LUT) component, an envelope computation value. The apparatus may store multiple computational values associated with the samples and select, based at least in part on the selected DPD kernel, at least one subset of computational values. The apparatus may generate an output sample that includes DPD based at least in part on combining the envelope computation value with the at least one subset of computational values. Numerous other aspects are described.

Abstract: This disclosure proposes a system in which two redundant asset tracking devices are used to monitor a single asset (such as a vehicle, which may contain a group of assets in cargo) via two distinct communication systems that operate in parallel, and which may operate in addition to any primary mode of communication used by the asset tracking devices (e.g., cellular communication). In some examples, each asset tracking device may communicate through separate and distinct satellite communication networks.

Abstract: A compact demodulation reference is disclosed for compatibility with reduced-capability user devices, and for enhanced throughput for high-performance user devices of 5G and 6G in high-density environments. The demodulation reference, in some embodiments, occupies only one resource element, yet provides sufficient information to enable a receiver to calculate all of the amplitude or phase modulation levels of the modulation scheme. For example, if the modulation scheme is 16QAM, the demodulation reference can include an I branch with the highest amplitude level of the modulation scheme and an orthogonal Q branch with the lowest amplitude level. Further examples apply to a multiplexed amplitude-phase modulation scheme. In each case, the receiver can calculate the remaining amplitude (or phase) modulation levels, and thereby demodulate a proximate message.

Abstract: Method, device, and system for deriving keys are provided in the field of mobile communications technologies. The method for deriving keys may be used, for example, in a handover process of a User Equipment (UE) from an Evolved Universal Terrestrial Radio Access Network (EUTRAN) to a Universal Terrestrial Radio Access Network (UTRAN). If a failure occurred in a first handover, the method ensures that the key derived by a source Mobility Management Entity (MME) for a second handover process of the UE is different from the key derived for the first handover process of the UE. This is done by changing input parameters used in the key derivation, so as to prevent the situation in the prior art that once the key used on one Radio Network Controller (RNC) is obtained, the keys on other RNCs can be derived accordingly, thereby enhancing the network security.

Abstract: Disclosed embodiments may include a method for authenticating calls for a call center where the user can authenticate before or after starting a call to a call center using an application on a user device. The system determines what level of authentication is necessary depending on the task the user wants to accomplish during the call. The system may direct the user to provide credentials, such as a username and password, for some tasks. Other tasks may require the user to verify their financial card by taking a photo of their financial card or tapping their financial card to their device and allow the device to interact with the financial card using NFC technology. Once appropriately authenticated, the system then allows the user to make a call to the call center and also sends a signal to the call center that the user has been previously authenticated.
