Abstract: The present invention relates to a method of reducing blind decoding attempts by a User Equipment (UE) in a telecommunication network. The method comprises configuring a Search Space (SS) configuration to the UE. A Base Station (BS) signals one of a subset of Aggregation Levels (ALs) to be monitored based on channel quality of the UE and an associated time period, and a value of multiplication factor (k) and an associated time period. The UE iteratively monitors a Physical Downlink Control Channel (PDCCH) on the ALs signalled by the BS till the UE stops receiving a new configuration. The UE performs one of adopting an original configuration, requesting the BS for a new configuration, utilizing a default configuration or utilizing an original configuration.

Abstract: Embodiments of the present invention provide a method and an IAB node for achieving timing alignment in an IAB network system. The method includes receiving, by the IAB node, at least one resource configuration and at least one parameter, wherein the at least one parameter comprises timing advance, timing advance offset, and timing error. The IAB node then determines timing for operation based on the received parameters. The timing may include UL transmission timing at a MT of the IAB node, DL transmission timing at a DU of the IAB node, and UL reception timing at the DU of the IAB node. Further, the IAB node performs an operation in at least one resource based on the resource configuration and the determined timing. This proposed invention ensures precise timing alignment for efficient communication within the IAB network system.

Abstract: A method of interference measurement for power management in an integrated access and backhaul (IAB) network. The method includes: requesting, by a Reference IAB node, configuration of a Downlink-Reference Signal (DL-RS) for measurement of interference, to one of: a Parent IAB node, by sending a trigger from a Mobile Termination (MT) of the Reference IAB node, and a Donor IAB node, by sending a request for instruction to the Parent IAB node for the configuration of the DL-RS, from a Distributed Unit (DU) of the Reference IAB node. The method also includes signaling, by the Parent IAB node, a configuration information of at least one of a periodic DL-RS, aperiodic DL-RS and semi-periodic DL-RS, to one of the MT of the Reference IAB node and DU of the Reference IAB node.
