    Abstract: Generally, a combination of the following features are present to provide a centralization solution, in some embodiments: Latency compensation and auto-calibration of the delay between the PHY and the radio; Leveraging loopback in the radio (ORAN standard defined); Measurement based on air timing and/or RRH early/late feedbacks; and ability to understand routing changes and recalibrate latency compensation. In one embodiment, a method is provided for providing workload redundancy in a virtualized radio access network (RAN), comprising: distributing a baseband workload from a plurality of cells onto a first virtualized baseband unit (vBBU) at a centralized site; provisioning a second vBBU as a redundant vBBU for the plurality of cells; synchronizing state from the first vBBU to the second vBBU according to a first periodicity; performing failover from the first vBBU to the second vBBU at a first time; and adjusting an operating latency during the performed failover such that the plurality of cells continues operation without an interruption of service.

    Abstract: In one embodiment, a method for providing communication Forward Error Correction (FEC) optimization for virtualized platforms, comprising: calculating a cut off time used to terminate total FEC processing duration; processing code blocks received in a subframe in an order defined by a sorting stage; and wherein processing code blocks comprises: checking if a current time has exceeded the cut off time cut off value; when the current time has exceeded the cut off time value, then setting a Cyclic Redundancy Code (CRC) FAIL and moving onto a next code block without decoding; when the current time has not exceeded the cut off time value, then running a single iteration of decoding and checking a code block CRC; when the code block CRC is PASS then decoding is successful and moving onto a next code block; when the code block CRC is FAIL then checking if a maximum number of FEC iterations has been reached; when maximum number of FEC iterations has not been reached repeating the steps of calculating and processing code blocks; and when maximum number of FEC iterations has been reached then moving onto the next code block.
