    Abstract: Techniques for generating signals with arbitrary noise shaping are discussed. One example apparatus configured to be employed within a transmitter can comprise a noise shaper configured to: receive an input signal x q ; and apply noise shaping to the input signal xq to generate a noise shaped output signal y q , wherein an in-band noise of the noise shaped output signal y q is below an in-band noise threshold of a spectral mask associated with the noise shaper, wherein an out-of-band noise of the noise shaped output signal yq is below an out-of-band noise threshold of the spectral mask, and wherein a noise of the output signal y q in each of a plurality of bandpass regions is below an associated noise threshold for that bandpass region of the spectral mask.

    Abstract: A method configured to clip an I signal and a Q signal according to a clipping boundary, includes receiving an I value and a Q value, wherein the I value and Q value define Cartesian coordinates of a data point being transmitted on the real and imaginary axes of the complex plane, respectively; determining a clipping error between the I value and the Q value and the clipping boundary; combining the clipping error with the I value to generate a clipped I value; combining the same clipping error with the Q value to generate a clipped Q value; and providing the clipped I value and the clipped Q value to a radio frequency digital-to-analog converter (RFDAC) in a transmit chain.

    Abstract: Aspects for uplink (UL) communications related to listen before talk (LBT) operations in wireless networks introduce techniques and network devices configured to enable these communications by considering contention window size adaptation and related conditions. In some aspects, a user equipment (UE) can switch between different types of LBT operations, including a complete, regular category 4 LBT operation / protocol and a single interval LBT protocol that is shorter in duration. A contention window size can be adapted independently per carrier in multi-carrier operations associated with UL transmissions that either includes or excludes carriers with the single interval LBT. In other aspects, a maximum channel occupancy time (MCOT) with multiple UL grants for different UL subframes can be utilized to determine the LBT processes for UL transmission.

    Abstract: Methods and devices for estimating an angle between a transmitter and a receiver for beamforming are provided. A method includes, with an antenna element in a first device, transmitting an omnidirectional pulse and detecting an echo of the pulse reflected from a second device. An angle between the first device and the second device is estimated based at least on a characteristic of the echo. The method includes transmitting the angle to the second device for use in beamforming between the first device and the second device.

    Abstract: A system that utilizes data over cable service interface specification (DOCSIS) over passive optical networks is disclosed. An example system includes core system in a passive optical network (PON), comprising a memory; and one or more processors configured to generate a downlink (DL) data stream comprising optical signals, in compliance with a data over cable service interface specification (DOCSIS); and provide the optical signals containing DL data to a network component in the PON over an optical fiber coupled between the core system and the network component. In some embodiments, the core system is located at a head end equipment at the internet service provider's facility. However, in other embodiments, the core system can have a distributed architecture, with a part of the core system located at the internet service provider's facility and a different part of the core system located at a different location.
