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

This abstract first appeared for US patent application 18654124 titled 'Physical Downlink Control Channel Monitoring Scaling

Simplified Explanation:

The patent application describes a method for a user equipment (UE) to monitor a Physical Downlink Control Channel (PDCCH) in multiple component carriers (CC) in carrier aggregation (CA) mode.

Key Features and Innovation:

• UE determines if it is operating in CA mode with CCs in different frequency bands.
• UE determines a span pattern for PDCCH symbols on different CCs and selects a monitoring type based on the span pattern.
• UE determines if CCs of a CA combination are collocated and selects a monitoring type based on this determination.

Potential Applications: This technology can be applied in wireless communication systems to enhance monitoring and control channel reception in CA mode.

Problems Solved: This technology addresses the challenge of efficiently monitoring PDCCH in CA mode with CCs in different frequency bands.

Benefits:

• Improved monitoring of control channels in CA mode.
• Enhanced efficiency in handling PDCCH symbols on different CCs.

Commercial Applications: Potential commercial applications include telecommunications equipment and network infrastructure for wireless communication systems.

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

Frequently Updated Research: Stay updated on research related to PDCCH monitoring techniques in carrier aggregation systems for the latest advancements in the field.

Questions about PDCCH Monitoring in Carrier Aggregation: 1. How does this technology improve the efficiency of monitoring control channels in carrier aggregation mode? 2. What are the key considerations for selecting a monitoring type based on span patterns in PDCCH symbols?

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.
