2 Aggregation across bands is supported in HSPA+ R9 for two downlink carriers, but each specific band combination, e.g. combination of band 1 and L-band, has to be defined in 3GPP.

17. Ever Increasing Smartphone Application Traffic
Excessive signaling due to frequent small data bursts in the background1
1) Higher ‘Signaling’ Pipe Capacity—FE-FACH
News Push
Location Updates
Instant Messaging 2) Compress uplink data
Social Networking
3) Smart Pipe—Gate Background Requests2
1Applicationspush notifications, updates, messages to users, even when application is not active, could be multiple times per hour.
This causes excessive network signaling due to setting up and tearing down the data channel for small, short, but frequent data bursts.

1R7/R8 allows small amounts of data to be efficiently transported in CELL-FACH state: up to 90% reduction in network signaling load due for social media example. 2Cell-DCH w/ R7 CPC allows non full buffer apps to use connected mode, DCH, more
efficiently (DTX/DRX). 3A main enhancements is downlink triggered feedback (CQI) and acknowledgements on the FACH reverse link, which makes FACH efficient like a regular HSPA link, see simulation assumptions in R1-112679

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

reduction improved Improved
Lower Level Optimizations: in uplink battery life
Uplink Data Compression (3GPP R12)1 signaling2 throughput
1 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
