More Information
Summary:Certain aspects of the present disclosure provide techniques for defending against false semi-persistent scheduling (SPS) activation detection and/or missed SPS release. According to certain aspects, a user equipment (UE) may detect one or more conditions for a semi-persistent scheduling (SPS) activation or release are met based on a downlink transmission, generate one or more metrics related to downlink transmission, and determine a valid SPS activation or release has occurred if the one or more metrics satisfy one or more criteria. According to certain aspects, a UE may determine a valid semi-persistent scheduling (SPS) activation has occurred, detect a number of PDSCH CRC failures, and implicitly declare an SPS release based on the detection.
