Abstract: A method and system for improving channel estimation for multi-user, multiple-input, multiple-output (MU-MIMO) systems through dynamic DM-RS port allocation in a 5G New Radio network is provided. The method comprises of allocating, by a Scheduler aware UE port allocation unit, one or more MU-MIMO ports to a plurality of code division multiplexing (CDM) groups for a plurality of UE users, performing, by a code selection unit, a code selection based on a number of allocated MU-MIMO ports, determining, by a spreading factor unit, a spreading factor allocated for each of the MU-MIMO ports in each of the plurality of CDM groups, determining, by a signalling unit, a Downlink Control Information (DCI) signalling of a Partial Port Occupancy (P-Poi) transmission for each UE and obtaining, by a channel estimation unit, channel estimates at the receiver through VSFOCC de-spreading based on the P-POI assigned for each of the MU-MIMO ports.

Abstract: A method and system for enabling transmission of uplink signal in a Multi-User Multiple Input Multiple-Output (MU-MIMO) system through dynamic DM-RS port allocation is provided. The method comprises of creating a scheduling information and a scheduling decision for MU-MIMO Scheduling of a plurality of User equipment's (UE's), transmitting the scheduling information as Downlink Control Indicator (DCI) payload bits over a Physical Downlink Control Channel (PDCCH) to the one or more paired UEs, demultiplexing the paired UEs based on the scheduling information, performing a Physical Uplink Shared Channel (PUSCH) Modulation based on the scheduling information extracted from the PDCCH from the one or more paired UEs, performing Cyclic Redundancy Check encoding and bit processing of the obtained DCI payload bits, performing antenna resource remapping and beam combining on the PUSCH channel, selecting DM-RS references for channel estimation and obtaining improved channel estimates at the receiver.

Abstract: A system and method for enabling downlink signal transmission in a Multiple-Input Multiple-Output (MU-MIMO) system is provided. The method comprises of creating a scheduling information based on MU-MIMO Scheduling of a plurality of User equipments (UES), multiplexing the plurality of UES paired based on the scheduling decisions across time, frequency and code, inputting transport blocks of each UE pushed on to a Downlink shared channel (DLSCH), performing bit processing of each of the CRC encoded UEs, inputting Code-rate (MCS) for data modulation mapping on a post bit processed data, assigning DM-RS ports to the UE based on allocated MCS and number of antenna ports from a scheduling information structure, adding, a Partial Port Occupancy information (P-Poi) for each UE along with the scheduler information structure required for demodulation at UE and enabling optimal channel estimation at UE by adding new DM-RS port combinations using reserved fields in the DCI messaging.
