Abstract: Accordingly the embodiments herein provide a for providing a Radio Link Control (RLC) status report based on a configuration of a Packet Data Convergence Protocol (PDCP) entity of a User Equipment (UE) in a wireless network system. The method comprises detecting, at the UE, that a RLC layer is configured to an Acknowledge Mode (AM), informing, at the UE, a t-reordering timer from the PDCP entity of the UE to a RLC entity of the UE, receiving, at the UE, a first Packet Data unit (PDU) by the entity and at least one second PDU by the RLC entity, detecting, by the UE, a PDU gap when the first PDU and the second PDU are not consecutive; providing, by the UE, the RLC status report to a transmitter side of the RLC entity of a network to recover packets missed in the PDU gap based on the t-reordering timer, and recovering, by the network, the packets based on the RLC status report.

Abstract: The various embodiments of the present invention disclose a method and system for performing Hybrid Repeat Request (HARQ) in cellular operations over unlicensed bands. The method comprises of checking, by an eNodeB (eNB), whether an unlicensed channel is occupied by a User Equipment (UE), initiating transmission of Redundancy Versions (RVs) corresponding to a HARQ process on the unlicensed channel if the unlicensed channel is occupied by the UE, verifying if a channel occupancy period is over and an acknowledgement for the HARQ process is received from the unlicensed channel and initiating a Redundancy Version (RV) bundling for retransmission of the bundled RVs without awaiting an acknowledgment for the HARQ process from the unlicensed channel, if the channel occupancy period is not over.

Abstract: Method and system for managing hidden node problem in a communication network. A receiving node in the system, upon receiving a data transmission request from at least one transmitting node, dynamically checks status of the channel between the transmitting node and the receiving node. If the channel is found to be clear for transmission, then the receiving node sends a message that indicates that the channel is clear, to the transmitting node, and the transmitting node starts transmitting the data. Upon receiving a message from the receiving node that the channel is not clear for transmission, then the transmitting node waits for a particular time period and attempts the connection again.
