Abstract: The present disclosure relates to a system (208) and a method thereof for managing resource element mapping. The system (208) generates data corresponding to downlink channels that include at least one of: a PSS, a SSS, a DMRS for a PBCH, and a CSIRS. Further, the system (208) receives data from processing chains at data reception modules. The processing chains correspond to a PBCH and a PDCCH, a PDSCH, a DMRS for the PDCCH and the PDSCH. Also, the system (208) stores the generated data and the received data in a buffer and maps the stored data at one or more data dispatch entities (226) at an appropriate position in a slot grid. Further, the system (208) transfers the mapped data, by the one or more data dispatch entities (226), serially to a modulator (306) based on a frequency and a time of a resource element of the slot grid.

Abstract: The present disclosure provides a system and method for implementing a physical layer architecture of base station in a heterogeneous platform, which involves time critical, computationally intensive, and huge data processing modules or processes. There are various channels in L1 which require time bound processing and each channel may be present multiple times. Implementation of all these channels over hardware requires huge amount of processing resources, complexity, and time. The system describes an overall L1 architecture in the heterogeneous computing platform, segregating the implementation of different modules or processes of L1 between Processing System (PS) and Programmable Logic (PL) system in an intelligent way to efficiently use the PL resources as well as PS core processing capabilities. The system also details a way of storing the output data of each protocol data unit (PDU) in bits instead of modulated complex samples, thereby saving memory.

Abstract: The present disclosure provides a system and a method for controlling overhead and functional split of a Resource Element (RE) mapper in a heterogeneous system. The system may receive physical channel Protocol Data Units (PDUs) including one or more parameters. The system may pre-process the one or more parameters of the physical channel PDUs. and generate one or more bits of control information per Physical Resource Block (PRB) based on the pre-processed one or more parameters. The system may arrange the generated one or more bits of control information per PRB in a grid, and transfer the grid including the generated one or more bits of control information per PRB from a processing system to a programmable logic of the heterogeneous system using a Direct Memory Access (DMA). The RE mapper in programmable logic space uses control grid to arrange/map data of various physical channels for over the air transmission.

Abstract: The present disclosure provides a system and method for polar encoding in a communication system. A polar encoder includes a cyclic redundancy check (CRC) attachment module, an interleaver, a frozen bit mapper, and a polar transformer.

Abstract: The present disclosure provides a system and a method for physical uplink shared channel (PUSCH) symbol rate processing. The system receives one or more signals from various users via a physical uplink shared channel (PUSCH). Further, the system bifurcates the input into two halves namely a symbol rate processing (SRP) stage and a bit rate processing (BRP) stage. The SRP stage stores one or more orthogonal frequency division multiplexing (OFDM) symbols associated with the signals. Further, the SRP stage processes the signal using an equalizer and stores an equalized output in an equalizer buffer. The equalizer uses two separate streams for processing even and odd samples and helps in completing the SRP stage quickly by reducing the processing time by fifty percent. The BRP stage receives an output from the equalizer buffer and decodes the output based on a user requirement.

Abstract: The present disclosure relates to a system and a method for processing data in control channels. The system provides control data including a plurality of bits from the control channels to a cyclic redundancy check (CRC) block. The system determines if the plurality of bits corresponds to broadcast channel (BCH) data or downlink control information (DCI) data, and interleaves the plurality of bits if the plurality of bits corresponds to the BCH data, or bypasses interleaving of the plurality of bits if the plurality of bits corresponds to the DCI data. The system performs rate matching of the plurality of bits, and determines a length of a plurality of rate matched bits by setting an aggregation level for the control channels. The system performs scrambling operation on the plurality of rate matched bits, and modulates the plurality of rate matched bits based on scrambling operation outputs.

Abstract: The present disclosure provides a system and a method for implementing rate recovery in the PUSCH and PDCH bit rate processing chain of network. The system packs log likelihood ratios (LLRs) data in such a way that for each equalized in phase and quadrature (IQ) symbols, a predetermined number of LLRs equal to the modulation order are packed. The system de-interleaves the packed LLRs by reading the most significant bit (MSB) LLRs row wise for the number of columns equal to the modulation order. The system uses a single buffer for de-interleaving, bit-deselection, and filler bit addition stages, thereby reducing memory requirement of the system. The system processes only a predetermined number of LLRs to a HARQ combining stage to optimize memory and reduce latency.
