Abstract: An electrochemical cell for a lithium ion battery has an anode comprising a silicon-based active material, a cathode comprising a cathode active material, and a capacity compensating electrolyte comprising a linear sulfite-based solvent and a lithium imide salt. A molar ratio of the lithium imide salt to the linear sulfite-based solvent is between 1:5 and 1:1.

Abstract: Systems, methods, and baseband processors are provided to generate or process symbols in a synchronization subframe. In one example, a method includes selecting non-consecutive orthogonal frequency division multiplexing (OFDM) symbols in a synchronization subframe. A transmitter is instructed to transmit demodulation reference symbols (DM-RS) on identical first sets of subcarriers in respective OFDM symbols of the selected non-consecutive OFDM symbols for a Physical Broadcast Channel (PBCH) using a same transmit beam, wherein a gap between two subcarriers in a respective set of the identical first sets of subcarriers is three subcarriers. The transmitter is instructed to transmit the PBCH on identical second sets of subcarriers in respective OFDM symbols in the selected non-consecutive OFDM symbols.

Abstract: Described is an apparatus of a first User Equipment (UE) operable to communicate with on a wireless network. The apparatus may comprise a first circuitry, and a second circuitry. The first circuitry may be operable to establish a parameter set defining 5G Physical Downlink Control Channel (xPDCCH) transmission to the UE. The second circuitry may be operable to generate, for transmission to the UE, one or more messages including the parameter set.

Abstract: A method is provided to generate and control transmission of reference symbols in a synchronization subframe, wherein a reference symbol includes reference values mapped to a block of K subcarriers. The method includes generating data corresponding to a basic subsequence of K−R1−R2 reference values, where R1 and R2 are integers such that 1≤R1+R2
