Abstract: According to an aspect of an embodiment, a base station configured for beamforming estimation in a massive multiple input multiple output (mMIMO) radio access network (RAN) (mMIMO-RAN) may comprise a processing device and a transceiver. The processing device may be configured to obtain a channel estimate for a user equipment (UE). The processing device may be configured to compute a first power level adjustment for a downlink (DL) signal and a second power level adjustment for the DL signal. The second power level adjustment may be based on a power constraint. The transceiver may be configured to transmit the DL signal to the UE.

Abstract: An example method may include identifying a first transmit identifier (TID) associated with a first node of a wireless network as ready to transmit and adding the first TID to a ready to transmit queue at a first point in time. The method may also include identifying a second TID associated with a second node of the wireless network as ready to transmit, and adding the second TID to the ready to transmit queue at a second point in time later than the first point in time. The method may additionally include selecting the second TID from the ready to transmit queue before selecting the first TID based on a projected increased overall throughput of packets within the wireless network when communicating with the second node before communicating with the first node.

Abstract: A calibration system comprises control circuitry and waveform capture circuitry. The control circuitry selects a first calibration waveform for input to a digital predistortion circuit of a transmitter. The capture circuitry captures a first waveform output by the transmitter in response to the first calibration waveform. The control circuitry compares the first calibration waveform to the captured first waveform. The control circuitry selects a first one of a plurality of mapping circuit configurations based on the result of the comparison, wherein the mapping circuit is configured to map outputs of a plurality of delay circuits among inputs of a plurality of filter taps. The control circuitry stores the one of the mapping circuit configurations in nonvolatile memory associated with the transmitter.

Abstract: A microwave backhaul transceiver comprises a plurality of antenna arrays, positioning circuitry, and signal processing circuitry. The microwave backhaul transceiver may determine, via the positioning circuitry, a location of the small cell backhaul transceiver. The microwave backhaul transceiver may, generate, via the signal processing circuitry, a beacon signal that uniquely indicates the location. The microwave backhaul transceiver may transmit the beacon signal via at least one of the antenna arrays. The beacon signal may be generated using a spreading code generated from a unique identifier of the location. The unique identifier of the location may comprise global positioning system coordinates and/or a street address. During the transmitting, a directionality at which the beacon radiates from a particular one of the antenna arrays may be varied such that the beacon is transmitted in multiple directions from the particular one of the antenna arrays.

Abstract: A system for wireless communication includes data processing hardware, and memory hardware in communication with the data processing hardware. The memory hardware stores instructions that when executed on the data processing hardware cause the data processing hardware to perform operations. The operations include generating a control frame including a frame control field. The operations also include transmitting the control frame including indicating data in the frame control field. The indicating data indicates that the control frame includes bandwidth information.

Abstract: A cable modem comprises transmitter circuitry, receiver circuitry, and memory. Upon power up of the cable modem in the field, the transmitter circuitry transmits one or more first signals into a network. The receiver circuitry measure echoes of the transmitted one or more first signals. The receiver circuitry generates an installation figure of merit based on the measured echoes and factory-calibration echo measurements stored in the memory. The communication device begins DOCSIS® network registration if the installation quality measurement meets a determined requirement and generates a notification to troubleshoot the installation of the communication device if the installation quality measurement does not meet a determined requirement.

Abstract: A system comprises local oscillator spur suppression circuitry, local oscillator generator circuitry), and beamforming circuitry. The local oscillator spur suppression circuitry is operable to generate a phase adjustment value. The local oscillator generator circuitry is operable to generate a local oscillator signal at a determined phase equal to a reference phase offset by the phase adjustment value. The beamforming circuitry is operable to receive the phase adjustment value, and generate a beamforming coefficient to be applied to a signal that is to be upconverted by the local oscillator signal and transmitted via an antenna element of a phased array, wherein the generation of the beamforming coefficient is based on the phase adjustment value and a location of the antenna element within the phased array.

Abstract: A multi-carrier transmitter apparatus is disclosed. The apparatus includes an outer encoder, a shell mapper and an inner encoder. The outer encoder is configured to receive a signal, perform error correction using an outer code on the received signal and generate an outer encoder signal. The shell mapper is configured to perform constellation shaping on a subset of bits from the outer encoder signal and generate one or more constellation shaping bits. The inner encoder is configured to perform inner error correction/encoding using an inner code on a second subset of bits from the outer encoder signal and generate an inner correction signal.
