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: 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.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Methods and systems for managing bearer configuration of user equipment (UE) with Evolved-Universal Terrestrial Radio Access Network-New Radio-Dual Connectivity (E-UTRAN-NR-DC) (EN-DC) capability. The UE detects connectivity issues in the UE itself and in interfaces connecting between a NR network with the UE, a LTE network, or an EPC that require disabling NR capability of the UE. The bearer configuration is determined and updated based on the detected connectivity issues. The UE signals the LTE network about the disabling of NR capability, requests enabling of data transfer through bearers of a MCG bearers associated with the LTE network in a current MCG RRC session, and prevents addition of SCG bearers associated with the NR network. The UE recovers data in the SCG bearers, lost due the issues in the NR network, through the MCG bearers. The UE can send a Tracking Area Update (TAU) to indicate the disabling of NR capability if the connectivity issues persist.
