    Abstract: Various embodiments of a radio frequency front end (RFFE) are disclosed, in one embodiment comprising: a 2G Global System for Mobile telecommunications (GSM) transceiver; a 4G Long Term Evolution (LTE) transceiver; and a combiner coupled to the 2G GSM transceiver and to the 4G LTE transceiver and to a radio head, coupled to the radio head via at least one stream of IQ samples, the at least one stream carrying samples derived from the 2G GSM transceiver and samples derived from the 4G LTE transceiver. The RFFE may be configured to provide downlink for 2G and 4G. The combiner may be configured to upsample 2G signals from the 2G GSM transceiver to a 4G carrier frequency. The RFFE may be configured to transmit both 2G and 4G on a same frequency band.

    IPC: H04W28/08 ,  H04W28/02

    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.

    IPC: H04L1/00

    CPC classification number: H04L1/0061

    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.

    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.
