METHODS AND APPARATUS FOR SIGNALNG AND STATE TRANSITION FOR PDCCH SKIPPING AND SSSG SWITCHING - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240195572 titled 'METHODS AND APPARATUS FOR SIGNALNG AND STATE TRANSITION FOR PDCCH SKIPPING AND SSSG SWITCHING

The patent application discusses systems and methods for adapting the monitoring of the Physical Downlink Control Channel (PDCCH) by a User Equipment (UE) in response to specific triggers.

• The UE initially monitors a default Search Space Set Group (SSSG) for Downlink Control Information (DCI) from a base station in the PDCCH.
• Upon receiving a first DCI trigger, the UE switches from monitoring the default SSSG to monitoring a first non-default SSSG associated with a first timer.
• Subsequently, upon receiving a second DCI trigger, the UE switches from monitoring the first non-default SSSG to monitoring a second non-default SSSG associated with a second timer.
• The first non-default SSSG may contain a non-empty SSSG with at least one associated search space, while the second non-default SSSG may be an empty SSSG with no associated search space to emulate PDCCH skipping.

Potential Applications: - This technology can be applied in wireless communication systems to enhance the efficiency of monitoring PDCCH. - It can improve the overall performance and reliability of communication between UEs and base stations.

Problems Solved: - Addressing the need for adaptive monitoring of PDCCH to optimize resource allocation and reduce interference in wireless networks.

Benefits: - Improved resource utilization and reduced interference in wireless communication systems. - Enhanced reliability and performance of PDCCH monitoring for UEs.

Commercial Applications: - Telecom companies can utilize this technology to enhance the efficiency of their wireless networks. - Equipment manufacturers can integrate this innovation into their products to improve overall system performance.

Questions about the Technology: 1. How does the adaptation of PDCCH monitoring benefit wireless communication systems? 2. What are the potential challenges in implementing this adaptive monitoring system in real-world networks?

Original Abstract Submitted

systems and methods provide for physical downlink control channel (pdcch) monitoring adaptation. a user equipment (ue) may monitor a default search space set group (sssg) for downlink control information (dci) from a base station in the pdcch. in response to a first dci trigger, the ue switches from monitoring the default sssg to monitoring a first non-default sssg associated with a first timer. in response to a second dci trigger, the ue switches from monitoring the first non-default sssg to monitoring a second non-default sssg associated with a second timer. the first non-default sssg may be a non-empty sssg including a search space set with at least one associated search space. the second non-default sssg may be an empty sssg with no associated search space to emulate pdcch skipping.
