  • Publication number: 20240039593
    Abstract: Coordinated signal processing at at least a first and second transceiver integrated circuit (IC) configured to commonly process aggregated signal-port IQ data packets; and, each transceiver IC having a transmit signal processing circuit configured to process the commonly-processed aggregated signal-port IQ data packets in accordance with frequency-specific beam-tilt information received in control message packets. The frequency-specific electronic beam tilt may be applied to either a designated component carrier, or to a designated subset of subcarriers within a given component carrier.

  • Publication number: 20240007160
    Abstract: An apparatus and method for uplink and/or downlink beamforming operation are disclosed. In one embodiment, each of a plurality of distributed secondary beamformer processors is associated with a respective region of an antenna array and associated with a respective beamforming submatrix. Each transmit or receive beamforming submatrix contains beamforming combining weights associated with antenna elements in the respective region of the antenna array. Further, each secondary beamformer processor uses the respective beamforming submatrix and a respective set of frequency-domain IQ data points (representing user data layers for transmission, or received FDIQ data from a corresponding set of transceiver ICs) to form a respective plurality of sets of beamformed frequency-domain IQ data points.

  • Publication number: 20240007159
    Abstract: A method and apparatus for multi-tier beamforming are disclosed. The method includes receiving a first-tier beamformed frequency-domain IQ data packet and a plurality of second-tier beamformed frequency-domain IQ data packets at a transceiver integrated circuit (IC) subarray. Each transceiver IC of the transceiver IC subarray (i) forms a multi-tier beamformed frequency-domain IQ data set by combining beamformed frequency-domain IQ data from the first-tier beamformed frequency-domain IQ data packet with beamformed frequency-domain IQ data from selected ones of the second-tier beamformed frequency-domain IQ data packets, (ii) generates a discrete-time-domain signal from the multi-tier beamformed frequency-domain IQ data set, and (ii) generates a modulated radio frequency (RF) signal from the discrete-time-domain signal.

  • Publication number: 20230413198
    Abstract: Systems and methods are disclosed for providing base station localization. In one embodiment the system includes a network including a base station such as a 5G gNodeB (gNB); a Hetnet Gateway (HNG) in communication with the gNB, wherein the HNG includes a location server and wherein the HNG virtualizes and abstracts a collection of base stations and provides a complex network under its purview as a simple base station to a mobile packet core network; a plurality of Hyper Sync Network (HSN) nodes in communication with the gNB and the HNG, wherein the plurality of HSN nodes listen to User Equipments (UEs) to locate the UEs and to synchronize clocks on the gNB with the collection of HSN nodes or other gNBs; and an Evolved Serving Mobile Location Center (E-SMLC) server in communication with the HNG and for reporting the location of a UE.

  • Patent number: 11849417
    Abstract: Systems and methods are provided for providing blind fast network synchronization for reducing LTE public safety products costs, comprising, in one embodiment: determining if location setup is required to mitigate timing offset due to propagation delay from the synchronization source and adjusting downlink timing, and when location setup is required then providing one of manual setup in terms of timing samples, limited power RACH based on SIB2 parameters, and based on observed time difference of arrival and position reference signal; coordinating network listening periods based on graphs and hash function to avoid common silence for two or more neighboring eNodeBs; and providing continuous synchronization using blind carrier estimation.

  • Publication number: 20230327719
    Abstract: In the case that several transmitting elements (e.g., a Tx chain) are simultaneously impaired, at least two different layouts are possible: the defected Tx chains are randomly scattered around the array; or, the defected Tx chains are aligned vertically on a random column (for 12 and 24 defected Tx chains—1 and 2 such columns are randomly chosen, respectively). It can be seen that the throughput is worse when the defected Tx chains are aligned in a column rather than randomly scattered, unless the defective Tx chains are known, in which case it is the opposite. This is because disabling an entire column has the most significant effect on the spatial null steering. When defected Tx chains are known the performance of all layouts are almost the same, though column yields slightly better results due to the antenna subarrays (2 vertical antennas have the same feed, therefore we lose less degrees of freedom).

  • Publication number: 20230299875
    Abstract: The disclosed invention presents new approach for FEC implementation as part of existing link between the PHY layer (L1) and MAC layer. In one embodiment a method for providing cellular network Forward Error Correction (FEC) offload, includes merging FEC functionality into the PHY-MAC interface including placing FEC functionality IPs inside a small form factor (SFP) transceiver and allowing configurations from the PHY controller; identifying data carrying packets; encoding/decoding of the data payload; and forwarding an encoded/decoded payload to the next layer.

  • Publication number: 20230103991
    Abstract: In a first embodiment, a method for determining a dynamic RACH response backoff indicator is disclosed, comprising: estimating a load on the PRACH, based on a number of preambles detected for each PRACH slot, noise floor level, and other Phy features; and using this as an input to perform dynamic backoff indicator selection. In a second embodiment, a method for determining dynamic RACH response backoff indicator is disclosed, comprising: determining, by using the information provided by the connected UEs, how much effort was required to connect with an eNB; and deciding, by a dynamic core allocation, if a zero backoff indicator can be used or a non-zero backoff indicator value is needed to be used.
