5 Carrier Aggregation fatter pipe to enhance user experience Up to 20 MHz LTE Carrier #1 Up to 20 MHz Up to 20 MHz Up to 20 MHz LTE Carrier #2 LTE Carrier #3 LTE Carrier #4 Aggregated Data Pipe Up to 100 MHz Up to 20 MHz LTE Carrier #5 Higher peak data rates Higher user data rates and lower latencies for all users More capacity for typical bursty usage 1 Leverages all spectrum assets 1 The typical bursty nature of usage, such as web browsing, means that aggregated carriers can support more users at the same response (user experience) compared to two individual carriers, given that the for carriers are partially loaded which is typical in real networks. The gain depends on the load and can exceed 100% for fewer users (less loaded carrier) but less for many users. For completely loaded carrier, there is limited capacity gain between individal carriers and aggregated carriers, 5

6 User experience Carrier aggregation increases capacity for typical network load Typical bursty smartphone applications You Tube Skype Burst Rate (normalized) Carrier aggregation capacity gain 2 10MHz Single Carriers 10MHz + 10MHz Carrier Aggregation 3 Pandora Data bursts 2 1 Partially loaded carriers Capacity gain can exceed 2x (for same user experience) 1 Idle time Load (Mbps) 1 Carrier aggregation doubles burst rate for all users in the cell, which reduces over-the-air latency ~50%, but if the user experience is kept the same (same burst rate), multicarrier can instead support more users for partially loaded carriers. The gain depends on the load and can exceed 100% for fewer users (less loaded carrier) but less for many users (starting to resemble full buffer with limited gain).

27 LTE broadcast is commercial Powered by Qualcomm Snapdragon processors 1 st World s 1st LTE Broadcast solution Gobi LTE Modem integrated into Snapdragon LTE Advanced Qualcomm Snapdragon and Gobi are products of Qualcomm Technologies, Inc. Source: KT Corp launches world s first commercial LTE Broadcast service By Nick Wood, Total Telecom Monday 27, January 2014 South Korean operator to use embms technology to deliver mobile TV service to Samsung Galaxy Note 3 smartphones. KT Corp on Monday launched the world s first commercial LTE Broadcast service, delivering mobile TV content to Samsung Galaxy Note 3 users. Called Olleh LTE Play, the service is based on embms (evolved multimedia broadcast multicast services) solutions developed in 27

28 LTE broadcast Higher capacity even with fewer users Leveraging LTE infrastructure and spectrum Unicast LTE Broadcast 7X 3X 1.7X X X X 1 user/ cell 2 users/cell 5 users /cell Network capacity/throughput Source: Qualcomm Research; Simulation assumptions - 2GHz carrier frequency, 5MHz spectrum, 500m site-to-site distance, cluster embms with 19 sites MBSFN deployment (100% of carrier usage), comparison with unicast (based on average throughput) 28 is based on the same amount of resource allocation.

29 Dynamic switching to broadcast offers even more flexibility Users accessing same content on unicast Users moved to broadcast Event or demand driven Pre-scheduled (e.g. at stadium only during games) Based on demand (e.g. breaking news) Seamless transition Make-before break connection Fully transparent to user Part of Rel Dynamically switch between unicast and broadcast (based on operator configured triggers) 1 This feature is called Mood (Multicast operation on Demand) in Rel 12 29
