  19. 19. Efficient Compression and Other Uplink Enhancements Improved Video/ Higher level Audio Codecs Optimization/Compression Uplink data compression is part of a group of 3GPP R12 uplink enhancements for improved coverage, capacity and load-balancing. High Level OS ~70% 30-40% reduction improved Improved Lower Level Optimizations: in uplink battery life Uplink Data Compression (3GPP R12)1 signaling2 throughput1 3GPP R12 proposal: Add payload (e.g. HTTP GET & POST packets) compression to the PDCP layer, header (RoHC/IPHC) compression already resides in PDCP. Uplink compression is suitable since highly compressible HTTP packets are ~70% of uplink smartphone data volume (based on Qualcomm logs). 2Reduction in Radio Resource Control (RRC) transitions, which drives network signaling, frees up resources for more data capacity 19
