SYSTEMS AND METHODS FOR CONNECTED MODE DISCONTINUOUS RECEPTION ON/OFF DETERMINATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17933923 titled 'SYSTEMS AND METHODS FOR CONNECTED MODE DISCONTINUOUS RECEPTION ON/OFF DETERMINATIONS

Simplified Explanation

The patent application discusses systems and methods for determining whether a user equipment (UE) should perform physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows. Here are some key points from the abstract:

• A radio access network (RAN) predicts if a downlink packet for a UE will arrive at the RAN buffer before the end of a CDRX on duration window, and sends downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) for the CDRX on duration window to indicate whether the UE should perform PDCCH monitoring during that window.
• The UE determines the current state of DL traffic and adaptively uses DCI monitoring based on the traffic state.
• Aggregation level adaptation by the RAN is also discussed.

Original Abstract Submitted

Systems and methods related to “on/off” determinations regarding the performance of physical downlink control channel (PDCCH) monitoring during connected mode discontinuous reception (CDRX) on duration windows are disclosed herein. In some cases, a radio access network (RAN) predicts whether a downlink (DL) packet for a UE will arrive at a buffer of the RAN prior to an end of a CDRX on duration window of the UE, and sends a downlink control information (DCI) with a cyclic redundancy check (CRC) scrambled by a power-saving radio network temporary identifier (PS-RNTI) (DCP) for the CDRX on duration window indicating whether or not the UE should perform PDCCH monitoring during the CDRX on duration window based on the prediction. In some cases, a UE determines a current state of DL traffic and adaptively uses DCP monitoring based on the current state of the traffic. Aggregation level adaptation by the RAN is also discussed.
