HSUPA Interference Cancellation Uplink coverage and capacity improvement Challenge users and control channel • Uplink interference caused by all data and voice users overhead reduces HSUPA performance
voice
• High data rate HSUPA users need high TX power causing even higher uplink interference to other users • Typically uplink has become the capacity bottleneck in many smartphone dominated networks
10 ms TTI users
Solution • Interference caused by increasing number of HSUPA users can be greatly reduced by advanced BTS receiver algorithm resulting in better better cell throughput
interference
• IC acts on the interference caused by 2 ms TTI users which are the h igh uplink data rate users. The interference caused by these users is canceled from other users within the same cell. 2 ms TTI users
Interference caused by 2 ms TTI users is cancelled from the signal received by other users

Dual Cell HSUPA HSUPA peak rates up to 11.5 Mbps • Dual-Cell HSUPA with QPSK enables peak rates up to 11.5 Mbps
Multiple parallel carriers in DL*
• Dual-Cell HSUPA combines two contiguous 5 MHz carriers in uplink • Bit rate benefits can be experienced in most of the cell area
Two parallel carriers for Dual-Cell in UL
• Dual-Cell HSUPA user rate gain up to 100% • Dual-Cell provides fast load balancing between two carriers.

Smart LTE Layering
Faster transition to LTE for improved user experience Challenge • How to quickly offload WCDMA network to LTE during high load states. •a How to minimize delay for LTE users when returning to LTE after making WCDMA voice call. • How to improve QoE for reducing churn of LTE capable UEs.
Solution Smart LTE Layering prevent high load state in WCDMA cell while LTE capable UEs exist
• This feature supports redirection from WCDMA to LTE via RRC Connection Release for R8 UEs which are in Cell_DCH state. • Triggers: State transition from Cell_DCH due to inactivity inactivity
“Go to E-UTRAN”

WCDMA and GSM Priorities Idle mode mode traffic traffic balancing - reduced setup times times and signaling signaling load • Idle mode traffic steering reduces need for handovers and redirections • Users are in the appropriate layer when there is need for data transmission • Within WCDMA layers broadcasted priorities can be used e.g. push users to small cell frequency layer • Frequency band prioritization is supported, e.g. prefer 900MHz for far away UEs and 2100MHz for close by UEs

Cell Reselection Using Priorities
Cell reselection from an LTE cell to another cell using different LTE frequency or even another RAT is done based on Absolute Priorities
UEs receive the configured absolute priorities for EUTRAN or inter-RAT frequencies via System Information Broadcasts (SIBs)
Absolute priorities have values ranging from 0 to 7, with 7 indicating the highest priority In these SIBs, EUTRAN or inter-RAT frequencies may be listed without providing priorities The UE only evaluates for reselection those cells using EUTRAN/Inter-RAT frequencies sent via SIBs with corresponding configured Absolute Priorities
I am on Idle state and camped on a cell. How do I choose a better cell to camp on?
