Physical Downlink Control Channel Monitoring Scaling - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240284218 titled 'Physical Downlink Control Channel Monitoring Scaling

Simplified Explanation: The patent application describes how a user equipment (UE) monitors a physical downlink control channel (PDCCH) in multiple component carriers (CC) when operating in carrier aggregation (CA) mode with different frequency bands.

• The UE determines the span pattern for PDCCH symbols on the first and second CC in CA mode.
• Based on the span pattern, the UE selects a PDCCH monitoring type.
• The UE also checks if the CCs in a CA combination are collocated and selects a monitoring type accordingly.

Key Features and Innovation:

• Monitoring PDCCH in multiple CCs in CA mode.
• Determining span pattern for PDCCH symbols.
• Selecting PDCCH monitoring type based on span pattern and collocation of CCs.

Potential Applications: This technology can be applied in advanced wireless communication systems to enhance monitoring and control channel efficiency.

Problems Solved:

• Efficient monitoring of PDCCH in CA mode.
• Optimizing PDCCH monitoring based on span pattern and CC collocation.

Benefits:

• Improved spectral efficiency.
• Enhanced UE performance in CA mode.
• Better utilization of frequency bands.

Commercial Applications: Potential commercial applications include telecommunications equipment, network infrastructure, and mobile devices for improved data transmission in CA mode.

Prior Art: Readers can explore existing patents related to PDCCH monitoring in carrier aggregation systems to understand the evolution of this technology.

Frequently Updated Research: Stay updated on advancements in 5G technology and carrier aggregation systems to learn about the latest developments in PDCCH monitoring.

Questions about PDCCH Monitoring in Carrier Aggregation Systems: 1. How does PDCCH monitoring impact the overall efficiency of carrier aggregation systems? 2. What are the key challenges in optimizing PDCCH monitoring in different frequency bands within a carrier aggregation setup?

Original Abstract Submitted

a user equipment (ue) monitors a physical downlink control channel (pdcch) in multiple component carriers (cc). the ue determines if the ue is operating in carrier aggregation (ca) mode having a first cc in a first frequency band and a second cc in a second frequency band. when the ue is operating in ca with a first cc in the first frequency band and the second cc in the second frequency band, the ue determines a span pattern for pdcch symbols being received on the first and second cc and selects a pdcch monitoring type based on, at least, the span pattern. a ue also determines if a first cc and a second cc of a ca combination are collocated and selects a pdcch monitoring type based on, at least, the determination of whether the first and second cc are collocated.
