    Abstract: A receiver performing a half cyclic prefix (CP) shift on received subframes is disclosed, comprising: an analog to digital conversion (ADC) module; a cyclic prefix (CP) removal module coupled to the ADC module configured to retain a portion of cyclic prefix samples; a fast Fourier transform (FFT) module configured to receive samples from the cyclic prefix removal module, and to perform a FFT procedure on the received samples using a FFT window, the FFT window being shifted ahead based on the retained portion of cyclic prefix samples, to output an orthogonal frequency division multiplexed (OFDM) symbol; and a rotation compensation module coupled to the FFT module, the rotation compensation module configured to perform phase de-rotation of the OFDM symbol.

    Abstract: This invention provides outer-loop link adaptation. A way to improve the BLER value and adapt better the link to the current transmission and scenario, is to recognize this kind of scenarios, and adapt the system to work according to it.
    In one embodiment, a method includes providing a service having a configuration including a Modulation Coding Scheme (MCS) margin size, a step size and a target Block Error Rate (BLER), wherein each BLER includes an adjusted step size according to a transmission type sensitivity; and adding to each Hybrid Automatic Repeat Request (HARQ) process waiting for a HARQ response, a parameter per code word that holds the used MCS value.

    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: A method is disclosed for providing a telecom microservice rolling upgrade, the method comprising: providing, by a Service Management and Orchestration (SMO), a new instance of F1 demux in a same cluster and namespace; advertising the new instance of the F1 demux to all PODs and micro services; informing, by the SMO, an old F1 demux to start a version upgrade to a new instance; sending, by the old F1 demux, a trigger to start a reconcile procedure to a new F1 demux; advertising that the old instance of the F1 demux is not available to take up new calls from internal PODs and micro-service, and is accepting traffic via the new F1 demux only; routing, by the old F1 demux, all incoming F1 traffic from a Distributed Unit (DU) to the new F1 demux; and instructing the DU, by the old F1 demux, to add a Transport Network Layer (TNL) association of the new F1 demux.
