Major Enhancements incdma2000 1x Revision C
• Support of 1x EV-DV Forward Packet Channel (F-PDCH)– Fundamentally new mode of operation– Peak data rate of 3.1 Mbps
• Changes specific to Layer 3– Dynamic T_TDROP– Enhanced Authentication (AKA, Message Integrity)– Decoupling PLCM from ESN– Fast Call Setup
15 June 2004 7
Forward Link Dynamic Resource Allocation
• Pool as much as possible of unused power and Walsh codes into the Forward Packet Data Channel (F-PDCH)

Major Enhancements incdma2000 1x Revision D
• Support of 1x EV-DV Reverse Packet Channel– Mobile station is required to support 1.23 Mbps; 1.53 and 1.84 Mbps are
optional– Shorter frames– Higher capacity
• QoS-related features– Support for multiple flows per user, and enhancements for QoS
• BCMCS (Broadcast and Multicast Service)• Changes specific to Layer 3
– Faster call setup• Direct Channel Assignment• Reduced SCI Operation• Traffic Channel Initialization Enhancements• Tracking zone reporting• Radio environment reporting
– Support for MEIDs (mobile equipment IDs, ESN replacement)– PLCM Enhancements– SYNC_ID enhancements – Multiple Services Enhancements
