  • Publication number: 20240113736
    Abstract: An interference mitigation system is provided herein. The interference mitigation system selects a threshold power range for signals received by at least one antenna and compares a power level of a signal to the threshold power range. Based on a determination of whether the power level of the first signal exceeds the threshold power range, the interference mitigation system identifies nodes that transmit or receive wireless signals and causes the nodes to stop transmitting or receiving signals for a selected duration of time. The interference mitigation system receives additional signals during the selected duration of time, and determines whether the first signal caused internal interference or external interference based on the additional signals and the first signal. The interference mitigation system causes the interference to be resolved based on the determination of whether the interference is internal interference or external interference.

  • Publication number: 20240073780
    Abstract: A method of communicating in a Fifth-Generation (5G) New Radio (NR) cellular telecommunication Radio Access Network (RAN) is performed by a gNobeB (gNB) and includes: determining that a first User Equipment (UE) that communicates with a Radio Unit (RU) is of a first type; determining that a second UE that communicates with the RU is of a second type; obtaining a first value that is associated with the first type; obtaining a second value that is associated with the second type, wherein the second value is different from the first value; controlling the first UE to use the first value as a t-Reassembly timer parameter used in a Radio Link Control (RLC) protocol; and controlling the second UE to use the second value as the t-Reassembly timer parameter used in the RLC protocol. The method may be performed independently for uplink and downlink directions.

  • Publication number: 20240064822
    Abstract: Systems and methods for enhanced PRACH 5G configuration by preventing interference with signal transmission. One such method includes: implementing a PRACH configuration in which the same root sequence index (RSI) is utilized across the sectors of the site, implementing the PRACH configuration in which a time shift is utilized for each preamble that provides each preamble with its own time slot, enabling multiple UEs to each send a preamble that is time shifted to arrive at the gNB at different times and avoid a RAPID (Random Access Preamble Identifier) mismatch, and receiving preambles that are frequency shifted and reducing PRACH interference among different sectors that causes a degradation of PRACH performance using shifts in time domain.

  • Publication number: 20240057041
    Abstract: Disclosed is a method of transmitting Synchronization Signal Blocks (SSBs) in a Fifth-Generation (5G) New Radio (NR) cellular telecommunication Radio Access Network (RAN). The method is performed by a Radio Unit (RU) device and includes: transmitting first symbols from a first antenna in a first sector, two or more of the first symbols including a first SSB; transmitting second symbols from a second antenna in a second sector, two or more of the second symbols including a second SSB; and transmitting third symbols from a third antenna in a third sector, two or more of the third symbols including a third SSB. The transmitting is performed during a first time slot and a second time slot. The symbols including the first SSB, the symbols including the second SSB, and the symbols including the third SSB are transmitted during different time periods.

  • Patent number: 9473371
    Abstract: A method and application server for dynamically determining a Reference Signal (RS) Power Boost level in a radio telecommunication network. The application server may be a Self-Optimized Network (SON) application server configured to received network performance information from Performance Management (PM) counters and configuration information from a configuration database server. The application server monitors a plurality of network Key Performance Indicators (KPIs), compares the KPIs to associated thresholds, and derives and assigns values to KPI threshold factors. The server calculates a scaling factor based on values of the KPI threshold factors, and calculates a dynamic RS Power Boost level by applying the scaling factor to a baseline RS Power Boost level.
