Abstract: Present disclosure generally relates to wireless telecommunication networks, particularly to systems and methods for retrieving Radio Access Network (RAN) information over E2 interface in open Radio Access Network (O-RAN). System determines, if RAN information is required by Near-RT RIC, based on occurrence of non-subscription-based O-RAN use case scenarios and deployment scenarios in Near-RT RIC. Further, system transmits RAN information request comprising RIC subscription request with on-demand event trigger, to E2 node via E2 interface associated with O-RAN, when RAN information is required. Furthermore, system receives RIC subscription acknowledgment corresponding to RIC subscription request, from E2 node. Additionally, system establishes short-time subscription with E2 for retrieval of RAN information from the E2 node, upon receiving RIC subscription acknowledgment from E2 node. Further, system retrieves RAN information through RIC indication from E2 node, upon establishing short-time subscription.

Abstract: Although MU-MEMO is a promising technology for wireless system but the field implementation for MU-MEMO has not been so successful, one of the reasons is significant overhead required to dynamically adapt to any changes in the wireless channel. The current technology is limited by the implementation complexity and have not yielded good performance in the field setup. Hence, the current disclosure proposes an end-to-end system and method to achieving MU-MIMO transmission, by providing a flexible framework for the selection of channel decomposition techniques, and significantly reduce computation complexity by limiting the number of prospective MU-MIMO candidates. The disclosure currently considers the QoS priority while selecting MU-MEMO candidate list which allows us to maintain the scheduler KPIs.

Abstract: Present disclosure generally relates to wireless telecommunication networks, and more particularly relates to systems and methods for retrieving Radio Access Network (RAN) information over E2 interface of Open Radio Access Network (O-RAN), using information request response procedure. System determines, if Radio Access Network (RAN) information is required by Near-RT RIC, based on occurrence of non-subscription-based O-RAN use case scenarios or deployment scenarios in Near-RT RIC. Further, system builds E2 Service Model (E2SM) container with required type of information, when RAN information is required. Furthermore, system encodes built E2SM container in E2 Application Protocol (E2AP) message. Thereafter, system transmits E2AP message as RAN information request to E2 node via E2 interface associated with O-RAN. Additionally, system receives RAN information response corresponding to RAN information request, from E2 node.

Abstract: The present invention provides an efficient and reliable systems and methods for facilitating FAIL SAFE possibilities in a Network by exploiting 3GPP defined Radio Resource Control (RRC) T310 (Radio-Link Failure Timer), N310 (Radio-Link Failure Counter), T311 (Radio Link Re-establishment Timer), N311 (Radio Link Re-establishment Counter) Timers and associated Counters to enable the L1 to recover within the combined duration of the sum of T310 and T311 timers, for example, typically, 100 msec following a L1 SW exception event.

Abstract: The present invention provides a method and system for facilitating improved downlink MIMO sector throughput in the presence of UE DC-offset. The system receives BLER from a plurality of UEs and tracks by L1 computing the DL BLER in a UE; checks if the BLER from the UE allocated with an RB containing a DC subcarrier is above a target BLER and if so the L1 increases the power of the RE containing the DC-subcarrier in steps of 3 dB. If the BLER improves in the UE, the L1 stops further increase of power on the DC subcarrier RE. The L1 maintains the improved UE/sector throughput and the subcarrier RE power. The system further supports a plurality of 5G NR UEs with different bandwidth wherein the DC-carrier of each UE can be worked out by the L2 by a set of predefined instructions.

Abstract: Traditionally in RU or RRH (Remote Radio Head) designs either frequency-synchronization or time-synchronization is present in the measuring wireless equipment. In such radios it is not possible to directly time-synchronize the measuring instruments to decode the constellation and downlink data channels of RU/RRH due to lack of timing synchronization signal. There are no system and method to directly time-synchronize the measuring instruments to decode the constellation and downlink data channels of RU/RRH due to lack of timing synchronization signal. The disclosure proposes system and method for deriving a timing synchronization signal for e.g., a 10 Mhz external frequency output provided by the RU and thereby time-synchronizing the measuring equipment to the RF signal transmitted by the RU, thus opening up a spectrum of various possibilities to use the equipment to monitor and diagnosis of an indoor-cellular system in deployment.
