5G 100 MHz
• Wideband 5G carrier is more efficient thanmulticarrier LTE
• Faster load balancing• Less common channel overhead• No
unnecessary guard bands between
carriers. LTE uses 10% for guard bands.
Up to 98 MHz

5G Lean Carrier for Enhanced Efficiency
• Cell specific reference signaltransmission 4x every
millisecond
• Synchronization every 5 ms• Broadcast every 10 ms
LTE
5G
• No cell specific reference signals• Synchronization every 20
ms• Broadcast every 20 ms
20 ms
Very limited capability for base station power savings due to
continuous transmission of cell reference signals
5G enables advanced base station power savings
= Primary synchronization
= Secondary synchronization
= Broadcast channel
= LTE cell reference signals
