Abstract:
Methods, systems, and devices for wireless communication are described that support a low peak-to-average power ratio (PAPR) precoded reference signal design for multiple-input, multiple-output (MIMO) transmissions. A user equipment (UE) may identify multiple sets of symbols associated with different reference signal waveforms, where each reference signal waveform may be associated with a low PAPR. In some cases, different single-carrier reference signal waveforms may be mapped to subsets of frequency resources through frequency division multiplexing (FDM) for a transmission on a single antenna. However, the addition of single-carrier waveforms through FDM for a transmission via an antenna may result in an uplink transmission having a high PAPR (e.g., as compared to single-carrier waveforms). The UE may reduce the PAPR of the uplink transmission by multiplexing the reference signal waveforms in the time domain (e.g., using time division multiplexing (TDM)).
Abstract:
Certain aspects of the present disclosure relate to methods and apparatus for transmitting sounding reference signals (SRS) in communications systems operating according to new radio (NR) technologies. An exemplary method that a user equipment (UE) may perform includes determining whether to transmit a sounding reference signal (SRS) using a discrete Fourier transform (DFT) spread orthogonal frequency domain multiplexing (DFT-S-OFDM) waveform or a cyclic prefix orthogonal frequency domain multiplexing (CP-OFDM) waveform, and transmitting the SRS using the determined waveform.

Abstract:
Techniques for supporting UE operation with enhanced uplink are described. A UE may select a first signature from a first set of signatures available for random access for enhanced uplink, generate an access preamble based on the first signature, and send the access preamble for random access while operating in an inactive state. The UE may receive an acquisition indicator (AI) for the first signature on an acquisition indicator channel (AICH) from a Node B. The UE may use a default enhanced dedicated channel (E-DCH) resource configuration for the first signature if the AI has a first predetermined value. The UE may determine an E-DCH resource configuration allocated to the UE based on an extended acquisition indicator (EAI) and a second signature if the AI has a second predetermined value. In any case, the UE may send data to the Node B using the allocated E-DCH resource configuration.
Abstract:
This invention focuses on the cellular differences in response to pH alterations and a key role of the cells' proliferative statuses in determining their responses. Therefore, methods and compositions are designed to use pH modifiers and cell proliferation inhibitors to treat or prevent diseases with pathogenesis attributable to inflammation, immune response, cell proliferation, or combinations thereof. The pH modifiers, particularly but not exclusively those that lower or resist the rise of pH, are used to deplete pathological inflammatory and/or proliferating cells. Conversely, pH modifiers that raise or resist the fall of pH are used to increase the population and the proliferation of normal protective cells.
Abstract:
An electrode includes a soft substrate, a metal layer in direct contact with the soft substrate, and a lithium layer formed directly on the metal layer, wherein the metal layer comprises wrinkles. The wrinkles are of a substantially uniform height, and the height is in a range of 100 nm to 20 μm. The wrinkles are typically separated by a substantially uniform distance, and the distance is in a range of 100 nm to 1000 μm. The wrinkles may be one dimensional or two dimensional. Fabricating an electrode includes forming a metal layer on a soft substrate, and forming a lithium layer on the metal layer. Forming the lithium layer on the metal layer yields uniform wrinkles in the metal layer. A battery may include the electrode as described.

Abstract:
Disclosed is a method for registration of scans of an object, such as a biological organ, by obtaining scans of the object that includes a first scan obtained with the object in a first position and a second scan obtained with the object in a second position different from the first position, extracting landmarks within each of the scans, flattening each of the scans, detecting feature points of each of the flattened scans, matching corresponding feature points of each of the flattened scans, performing a harmonic map registration using the matched corresponding feature points and displaying the registered scans.

A method for wireless communications is provided. The method includes generating at least one adjustable power parameter for an acquisition indicator channel (AICH) and generating at least one adjustable power parameter for an extended acquisition indicator channel (E-AICH). The method also includes generating at least one power offset representing differences between the AICH and the E-AICH.
Abstract:
Techniques for reporting acknowledgement (ACK) information and channel quality indication (CQI) information in a wireless communication system are described. A user equipment (UE) may be able to receive data from up to two cells with dual-cell operation. The UE may determine CQI information for a first cell, determine CQI information for a second cell, and send the CQI information for both cells on a feedback channel with a single channelization code. The UE may process a control channel from each cell and, if control information is received from the cell, may further process a data channel from the cell to receive data sent to the UE. The UE may determine ACK information for each cell based on processing results for the data and control channels from that cell. The UE may send the ACK information for both cells on the feedback channel with the single channelization code.
