Abstract: Accordingly embodiments herein achieve signaling method and system (2000) for provisioning signalling in an Integrated Access Backhaul (IAB) network (1000). The method includes providing a set of modifications in uplink and downlink signaling for an IAB node (100). The modifications either help to reduce the control channel payload or enable more flexible signaling of resources, improve efficient control channel scheduling and also avoid conflicts that might arise due to discrepancies between semi static and dynamic resource allocation.

Abstract: The present invention relates to a method of signalling in an Integrated Access and Backhaul (IAB) network. The method comprises signalling metrics from a parent IAB node to a child IAB node for association of the child IAB node with the parent IAB node. Information related to multiplexing capability and supported modes of operation is signalled from the child IAB node to the parent IAB node. An active mode of operation is determined at the child IAB node. Timing Advance (TA) for each active mode of operation, guard information for each active mode of operation, and exchanges for In-Band Full Duplexing (IBFD) mode of operation are signalled. Further, fallback capability of IAB nodes during presence of Self-Interference (SI) is also signalled.

Abstract: Precoding for multiple transmission streams in multiple antenna systems. Disclosed herein is a general method that transmits signal from multiple antennas using a one/two dimensional precoder. This precoder is fixed in a given resource block (RB) or slot, which is composed of P subcarriers and Q OFDM symbols (where the values for P and Q are greater than or equal to 1). The precoder in each resource block may take same or different values, which span the two dimensional time-frequency grid. The precoder is chosen as a function of either logical frequency index or physical frequency index of the RB.

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: Accordingly, embodiments herein disclose a method for signal synchronization in orthogonal frequency-division multiplexing (OFDM) based Narrow Band-Internet of Thing (NB-IoT) system. The method includes generating a New Radio-Narrowband Primary Synchronization Signal (NR-NPSS). Further, the method includes mapping each Zadoff-chu sequence of 14 Zadoff-chu sequences of the NR-NPSS to resource elements of each OFDM symbol of 14 OFDM symbols in an NR-NPSS subframe. Further, the method includes transmitting the NR-NPSS subframe comprising the mapped NR-NPSS to at least one User Equipment (UE) (200), receiving the NR-NPSS subframe comprising the transmitted NR-NPSS by a base station (100), generating a reference NR-NPSS, mapping each of the 14 Zadoff-chu sequences of the NR-NPSS to resource elements of each OFDM symbol of 14 OFDM symbols in an NR-NPSS subframe, and detecting the NR-NPSS from the received NR-NPSS subframe using the reference NR-NPSS to obtain the time and frequency synchronization in the NB-IoT system.
