Abstract: Various aspects of the present disclosure provide for methods, apparatus, and computer software for multiple access to a channel carrying a common uplink burst transmitted by users that utilize two different modes. Specifically, a coupled mode provides for range extension for users at a cell edge, while a decoupled mode provides for user data transmissions within the common uplink burst. Multiple access between these different modes may be provided in a non-orthogonal scheme by moderating the amount of interference between the respective modes. Further, multiple access between these different modes may be provided in an orthogonal scheme by utilizing interleaved frequency division multiple access (IFDMA).

Abstract: An n-type metal-oxide-semiconductor (NMOS) transistor comprises a graphene channel with a chemically adsorbed nitrogen dioxide (NO2) layer formed thereon. The NMOS transistor may comprise a substrate having a graphene layer formed thereon and a gate stack formed on a portion of the graphene layer disposed in a channel region that further includes a spacer region. The gate stack may comprise the chemically adsorbed NO2 layer formed on the graphene channel, a high-k dielectric formed over the adsorbed NO2 layer, a gate metal formed over the high-k dielectric, and spacer structures formed in the spacer region. The adsorbed NO2 layer formed under the gate and the spacer structures may therefore attract electrons from the graphene channel to turn the graphene-based NMOS transistor off at a gate voltage (Vg) equal to zero, making the graphene-based NMOS transistor suitable for digital logic applications.

Abstract: To determine a location of a client device in a wireless network having at least first and second network devices, with known locations, one of the network devices transmits a message to the other network device and the other network device responds with an acknowledgement message. A client device receives the message and the acknowledgement message as well as respective times indicating actual times at which the message and the acknowledgement message were processed by one of the first and second network devices. The client device determines its location based on the times at which it received the message and the acknowledgement message and the difference between the actual processing times. This location may be refined by determining an angle between the client device and at least one of the network devices having multiple antennas and being configured for steered beam communications.

Abstract: A method for propagating a signal from an output driver on a PCB to a number of chips on the PCB. The signal is propagated from a first transmission line connected to the output driver, to a second transmission line connected to the first transmission line and a first chip, and to a third transmission line connected to the first transmission line and a second chip. The second transmission line has a length greater than or equal to 10 times the length of the first transmission line, and the third transmission line has a length greater than or equal to 10 times the length of the first transmission line. The lengths of the first transmission line, the second transmission line, and the third transmission line cause a reduction in reflections of the signal due to a change in impedance at a junction of the first, second, and third transmission lines.

The same or different device determines, based on the element in the sample entry, that all SPSs that are activated when the stream to which the sample entry applies is decoded have syntax elements that indicate that temporal sub-layer up-switching to any higher temporal sub-layer can be performed at any sample associated with the SPSs.

Abstract: Systems and techniques are disclosed to reduce pilot overhead by providing common reference signals coded with cover codes that are orthogonal in time and frequency domains. Common reference signals that are coded by cover codes orthogonal in both domains can be de-spread in both the time and frequency domains for improved resolution and larger pull-in windows for both. Also disclosed is semi-uniform pilot spacing in both the frequency and time domains. In a time domain, a first pilot symbol pair is spaced by a first time interval from each other and a second pilot symbol pair is spaced by a second time interval from the first pair, the second interval being greater than the first. In a frequency domain, a first set of pilot symbols is densely placed in a selected frequency band and a second set of pilot symbols is sparsely placed surrounding and including the selected frequency band.

The apparatus may be a processor. The processor computes a non-linear function ƒ(x) for an input variable x, where ƒ(x)=g(y(x),z(x)). The processor determines an integer n by determining a position of a most significant bit (MSB) of an input variable x. In addition, the processor determines a value for y(x) based on a first look-up table and the determined integer n. Also, the processor determines a value for z(x) based on n and the input variable x, and based on a second look-up table. Further, the processor computes ƒ(x) based on the determined values for y(x) and z(x).
