AI Technical Summary
⚠Technical Problem
LPWA networks face challenges with PDCCH blocking due to PDCCH repetition for coverage enhancement, leading to resource consumption and inability to schedule other UEs, while maintaining low device complexity and power consumption.
⚗Method used
Configuring a UE search space with multiple CORESETs and using indication signals like WUS to selectively monitor one CORESET at each occasion, minimizing blocking and reducing complexity.
🎯Benefits of technology
This approach avoids PDCCH blocking, minimizes UE complexity and power consumption, and expands the use cases for 6G LPWA networks by enhancing adaptability.

Abstract
Systems, methods, apparatuses, and computer program products methods for configuring UE search space with multiple CORESETs. One method may include receiving, from a network entity, at least one search space configuration associated with a plurality of control resource sets, CORESETs; determining, based on at least one defined rule or network configuration, at least one CORESET from the plurality of CORESETs on a search space to monitor; and monitoring physical downlink control channel, PDCCH, on the determined at least one CORESET.
