name: CFR
full_form: Crest Factor Reduction
context: A CFR configured by RRCReconfiguration message is defined for multicast scheduling as an 'MBS frequency region' with a number of contiguous PRBs confined within and with the same numerology as the DL BWP, and multicast scheduling may have specific characteristics (e.g., PDCCH, PDSCH and SPS configurations). The CFR for the multicast reception in RRC_INACTIVE state and the CFR for broadcast can be configured differently. If one CFR is not completely contained within the other CFR, the UE in RRC_INACTIVE state is not required to receive both broadcast and multicast simultaneously. Two HARQ-ACK reporting modes are defined for MBS: - For the first HARQ-ACK reporting mode, the UE generates HARQ-ACK information with ACK value when a UE correctly decodes a transport block or detects a DCI format indicating an SPS PDSCH release; otherwise, the UE generates HARQ-ACK information with NACK value. - For the second HARQ-ACK reporting mode, the UE does not transmit a PUCCH that would include only
description: Crest Factor Reduction (CFR) is a technique used in telecommunications to reduce the peak-to-average power ratio of a signal. In the context of 3GPP TS 38.300, CFR is specifically applied to multicast scheduling and broadcast configurations within the physical layer.
explanation: The provided context from 3GPP TS 38.300 highlights the application of CFR in managing signal characteristics for efficient transmission. This indicates that CFR is a technological aspect related to signal processing and management, hence classified as Technology.
