OVERLAPPING PHYSICAL DOWNLINK CONTROL CHANNEL CANDIDATE THRESHOLDS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17387842 titled 'OVERLAPPING PHYSICAL DOWNLINK CONTROL CHANNEL CANDIDATE THRESHOLDS

Simplified Explanation

Methods, systems, and devices are disclosed for wireless communications that support overlapping physical downlink control channel (PDCCH) candidate thresholds. Here are the key points:

• The patent application describes techniques for determining the number of overlapping PDCCH candidates within a time interval for each subcarrier spacing (SCS) configuration.
• A user equipment (UE) receives signaling from a base station indicating one or more PDCCH monitoring configurations.
• The UE monitors the PDCCH for control information based on the received PDCCH monitoring configurations and the number of overlapping PDCCH candidates.
• The number of overlapping PDCCH candidates must satisfy the determined threshold number of overlapping PDCCH candidates.

Potential applications of this technology:

• This technology can be applied in wireless communication systems that use PDCCH for control information transmission.
• It can improve the efficiency and reliability of PDCCH monitoring by dynamically adjusting the number of overlapping PDCCH candidates based on the SCS configuration.

Problems solved by this technology:

• Overlapping PDCCH candidates can cause interference and make it challenging for a UE to correctly decode control information.
• By determining a threshold number of overlapping PDCCH candidates and monitoring the PDCCH accordingly, this technology helps mitigate interference and improve the accuracy of control information decoding.

Benefits of this technology:

• Improved reliability: By monitoring the PDCCH based on the determined threshold number of overlapping PDCCH candidates, the UE can more accurately decode control information, leading to improved reliability in wireless communications.
• Enhanced efficiency: Dynamically adjusting the number of overlapping PDCCH candidates based on the SCS configuration allows for efficient use of system resources and better overall system performance.

Original Abstract Submitted

Methods, systems, and devices for wireless communications are described that support overlapping physical downlink control channel (PDCCH) candidate thresholds. In some examples, a user equipment (UE) may determine, for each subcarrier spacing (SCS) configuration of a set of SCS configurations, a threshold number of overlapping PDCCH candidates within a time interval. The UE may receive, from a base station, signaling indicating one or more PDCCH monitoring configurations. In some examples, the UE may monitor the PDCCH for control information according to the one or more PDCCH monitoring configurations and a number of overlapping PDCCH candidates, where the number of overlapping PDCCH candidates may satisfy (e.g., be less than or equal to) the threshold number of overlapping PDCCH candidates.
