Systems and Methods for Base station configuration of PDCCH Monitoring in a wireless device - A simplified explanation of the abstract

This abstract first appeared for US patent application 17598233 titled 'Systems and Methods for Base station configuration of PDCCH Monitoring in a wireless device

Simplified Explanation

The patent application describes a method and device for determining a monitoring configuration for a physical downlink control channel (PDCCH) in a wireless device operating in the 5G new radio (NR) spectrum above 52.6 GHz.

• The method specifies the monitoring of PDCCH for one subcarrier spacing (SCS) selected from a group of SCSs related to the spectrum.
• The monitoring limits associated with each SCS are applied per slot per CC (component carrier).
• The user equipment (UE) decode complexity for performing the monitoring limits for different SCSs in the group is equal.
• The monitoring limits associated with each SCS are applied over a duration of a slot group consisting of multiple slots.

Potential applications of this technology:

• Wireless communication systems operating in the 5G NR spectrum above 52.6 GHz.
• Devices and networks utilizing subcarrier spacing for PDCCH monitoring.
• Improving the efficiency and performance of PDCCH monitoring in high-frequency wireless communication.

Problems solved by this technology:

• Efficiently determining the monitoring configuration for PDCCH in high-frequency wireless communication.
• Ensuring equal UE decode complexity for different SCSs in the monitoring configuration.
• Optimizing the monitoring limits for different SCSs to improve overall system performance.

Benefits of this technology:

• Enhanced efficiency and performance of PDCCH monitoring in high-frequency wireless communication.
• Equal UE decode complexity for different SCSs simplifies implementation and operation.
• Improved system performance and reliability in 5G NR networks operating above 52.6 GHz.

Original Abstract Submitted

A method and apparatus for determining a physical downlink control channel (PDCCH) search space monitoring configuration for a wireless device that specifies PDCCH monitoring for one subcarrier spacing (SCS) selected from a group of subcarrier spacings (SCSs) that are related to a spectrum in 5G new radio (NR) above 52.6 GHz are described. In one embodiment, the monitoring limits associated with each of the SCSs are applied per slot per CC and the user equipment (UE) decode complexity associated with performing the monitoring limits for the different SCSs in the group is equal. In one embodiment, the monitoring limits associated with each of the SCSs are for a slot group of a plurality of slots and are for application over a duration of the slot group.
