Publication number: 20250097748Abstract: Systems and methods described herein provide new parameters for RAN configurations to manage network slices. A network device stores definitions for multiple mode parameters for a central unit (CU) of a radio access network (RAN), wherein each mode parameter defines a section of the CU that provides a relative performance level for a slice subnet over the RAN. The network device receives a slice configuration request for a network slice that identifies one of the multiple mode parameters and instantiates the network slice to operate over the section of the CU that is associated with the identified one of the multiple mode parameters. Additionally, a slice anti-affinity (SA) parameter is provided to selectively isolate network slices and improve slice reliability within the RAN.Type: ApplicationFiled: September 14, 2023Publication date: March 20, 2025Inventors: Deepak Majjiga, Ayman Ahmed, Jin Yang

Publication number: 20160241248Abstract: A highly integrated monolithic self-compensated oscillator (SCO) with high frequency stability versus temperature variations is described, together with a cost effective single insertion point trimming (SPT) algorithm. The SPT is utilized to adjust the phase and frequency of the SCO to meet frequency stability versus temperature and frequency accuracy requirements for a reference clock. The techniques used in the SPT algorithm provide a robust, fast and low testing cost for the SCO. Moreover, the concepts and techniques utilized in the SCO SPT can be used effectively for any temperature compensated oscillator (TCO) including TCXO, MEMS, FBAR and RC oscillators. Additionally, the described SPT algorithm is capable of measuring the temperature sensitivity of any oscillator, estimating suitable temperature compensation parameters and adjusting the oscillator frequency to the required value simultaneously.Type: ApplicationFiled: February 3, 2016Publication date: August 18, 2016Inventors: Ahmed Elkholy, Ayman Ahmed
