Although MU-MIMO is a promising technology for wireless system but the field implementation for MU-MIMO has not been so successful, one of the reasons is significant overhead required to dynamically adapt to any changes in the wireless channel. The current technology is limited by the implementation complexity and have not yielded good performance in the field setup. Hence, the current disclosure proposes an end-to-end system and method to achieving MU-MIMO transmission, by providing a flexible framework for the selection of channel decomposition techniques, and significantly reduce computation complexity by limiting the number of prospective MU-MIMO candidates. The disclosure currently considers the QoS priority while selecting MU-MIMO candidate list which allows us to maintain the scheduler KPIs.

Systems and method of improved resources sharing in 5G/6G wireless system

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.

Methods to reduce number of blind decoding attempts done by a user equipment

A method includes receiving at least one parameter associated with the each of at least one IAB node (), determining a resource configuration comprising of resources to be allocated to the DU of each of the at least one IAB node () based on at least one resource allocation criteria and the at least one parameter, indicating the resource configuration for the DU of each of the at least one IAB node (). The method includes signaling a timing advance (TA) value to at least one IAB node () based on a plurality of parameters, evaluating at least one of a UL-Tx timing and a DL-Tx timing based on the TA value signaled, configuring a cell-specific signal and channel (CSSC) to the DU of the reference node based on the at least one parameter, and timing alignment in a IAB network ().

The present invention relates to a method of signalling in an Integrated Access and Backhaul (IAB) network. The method comprises signalling information related to multiplexing capability and supported modes of operation from the child IAB node to the parent IAB node. An active mode of operation is determined at the child IAB node. The configuration to operate in the active mode of operation is signalled to the child IAB node. Timing Advance (TA) for each active mode of operation, guard information for each active mode of operation are signalled as configuration for the active mode of operation. Further, the method comprises signalling exchanges for fallback from one mode of operation to another at child IAB nodes.

Method of signalling in an integrated access and backhaul network

Accordingly embodiments herein achieve signaling method and system () for provisioning signalling in an Integrated Access Backhaul (IAB) network (). The method includes providing a set of modifications in uplink and downlink signaling for an IAB node (). 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.

Signaling methods to alter the number of control channel blind decodings in integrated access and backhaul

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.
