LTE-A Enhancement #3: multiple antenna transmission
• From 4 antennas/streams to 8 antennas/streams– Baseline being 4x4 with 4 UE Receive Antennas– Peak data rate reached with 8x8 SU-MIMO
• From 1 antenna/stream to 4 antennas/streams1, 2 or 4 transmitters
New for LTE-A
– Baseline being 2x2 with 2 UE Transmit Antennae– Peak data rate reached with 4x4 SU-MIMO
• Focus is initially on downlink beamsteering up to 4x2 antennas – SM is less attractive
• Challenges of higher order antenna transmission– Creates need for tower-mounted remote radio

Design Challenge #1 – Working Algorithmic Reference
– Are they compatible? Flexible? Updated? – Are they from a trusted source?– Can you re-use tests and scripting?
• Are the BB and RF teams working from the same IP references?
• Everyone needs some level of algorithm reference

Enhanced Uplink Multiple Access Design and test challenges
• Clustered SC-FDMA increases PAR by a few dB adding to transmitter linearity challenges
• Simultaneous PUCCH and PUSCH also increases PAR• Both feature create multi-carrier signals within the channel
bandwidth• High power narrow PUCCH plus single or clustered SC-FDMA
creates large opportunity for in-channel and adjacent channel spur generation– May require 3 to 4 dB power amp backoff for Rel-8 PA

May require 3 to 4 dB power amp backoff for Rel 8 PA– Some scenarios may require 10 dB backoff.

The use of clustered SC-FDMA increases the PAPR above non-clustered SC-FDMA, but not as much as full OFDM which can exceed the PAPR of Gaussian noise

C t F t R d ti t t i ti l t ff t thi i
Design Challenge #3 – Carrier Aggregation stressing RF
• Crest-Factor Reduction strategies are essential to offset this increase
• Increased RF bandwidth also exposes frequency-dependence and other analog degradations, which crosses multiple CC’s
• Combinations of several factors: Non-contiguous Carrier Aggregation, the multitude of possible RF Bands, and number of MIMO layers make these RF designs a true challenge.

• How do you translate real RF limitations back up to system-level performance? Can you correlate PHY simulations with measurements?

DPD of LTE-Advanced, using M9330A/M9392A 2x20MHz + 2x20MHz non-contiguous CCs, (100MHz signal BW)
For BW 140-250 MHz, Agilent M9392A is available
- 12bits ADC- up to 250MHz bandwidth
over 2 5GHz- over 2.5GHz - may require wideband AWG
For BW < 140 MHz: Agilent PXA is recommended
- 14bits ADC- can reach down to -100dBm- greater DPD improvements

• MIMO “multiplicity” is adding to the verification effort; Do 8x4 and 8x8 provide the performance for an ROI?
• Virtual techniques (Agilent MIMO OTA approach and simulation links
Design Challenge #4 – MIMO and Channel considerations
Virtual techniques (Agilent MIMO OTA approach, and simulation links from bottom-up EDA flows) can bridge gaps
• A surprising level of accuracy is attainable at the algorithm/architecture stage of a design
• Comparable algorithms can be used in both simulation and at-speed hardware faders; this symmetry can ease the transition to verification
