Abstract: A method for handling data, dangling in a new radio (NR) leg of a split bearer, by a user equipment (UE) is disclosed. The method comprises predicting occurrence of NR uplink (UL) leg switch; sending a buffer status report (BSR) pertaining to protocol data units (PDUs) in radio link control (RLC) layer and media access control (MAC) layer in the NR leg based on predicting the occurrence of NR UL leg switch; and initiating recovery of dangling PDUs in the NR leg after the occurrence of the NR UL leg switch, wherein the recovery includes sending the dangling PDUs to a long term evolution (LTE) leg of the split bearer.

Abstract: Accordingly the embodiments herein disclose a method for cell reselection by UE in a connected mode. The method includes measuring signal strength of neighboring cells in one or more inter-radio access technology (inter-RAT) frequencies while camped on a serving cell in the connected mode. Further, the method includes determining power class (PC) capability of the neighboring cells by scanning a band corresponding to the Evolved Absolute Radio Frequency Channel Number (EARFCN) of the neighboring cells, by reading SIB from neighboring cell, by reading a control channel message. Furthermore, the method includes reselecting to a neighboring cell using the determined power class capability when the measured signal strength of the neighboring cell meets the pre-defined reselection threshold.

Abstract: The present invention generally relates to system and methods to avoid/reduce delay with SMS delivery in Dual SIM Dual Standby (DSDS) devices. As per the proposed solution, retry timer is stopped once Refresh Register is received for SIM-2 (i.e. Stand by SIM) to indicate the service resume and delivery the SMS immediately. The proposed solution has scope of Change Request with 3GPP to update the SMSC retry algorithm based on Refresh Register from service resumed SIM.

Abstract: Methods and systems for routing data through IAB nodes 201, 202 in 5G communication networks. Embodiments herein allow routing data between a UE 206 and an IAB donor 200 though IAB nodes 201, 202 using adaptation layers of the IAB donor 200 and the IAB nodes 201, 202. The adaptation layers of the IAB donor 200 and the IAB nodes 201, 202 are configured by defining adaptation layer header and functionality. Mapping is performed between bearers/RLC channels of the UE 206 and the IAB node 202 and between bearers/RLC channels of the IAB nodes 201, 202 and the IAB donor 200. The means to perform the mapping is specified by the adaptation layers of either the IAB donor 200 or the IAB nodes 201, 202. The data is routed through the bearers/RLC channels. The embodiments include managing RLC layer functionality using either hop-by-hop ARQ or end-to-end ARQ.
