Qualcomm: LTE Direct - Operator enabled proximity services

  1. 1. March 2013LTE DirectOperator enabled proximity services
  2. 2. Hyper connected world around you Connected Home Stores / Restaurants Professional Family, Contacts Friends & Pets 2
  3. 3. To discover… WHO’S AROUND? WHAT’S NEAR BY? Connected Home Stores /IT RELEVANT NOW? IS Restaurants Professional Family, Contacts Friends & Pets 3
  4. 4. You need a “Wireless Sense” Connected Home Stores / Restaurants ProfessionalFamily, Friends Contacts & Pets 4
  5. 5. LTE Direct : Operator enabled proximity services LTE “Native” Direct Device-to-Device Solution Uses LTE spectrum, and network; Candidate feature in 3GPP R12 “Always-ON” Privacy Sensitive Discovery Autonomously discovers 1000s of relevant devices/services in a battery–efficient way Enables New and Enhances Existing Apps/Services Differentiated app/services enabled by proximate discovery; Opportunities for operators to monetize Next-Gen Solution for Emergency Services Robust; Cost-effectively leverages commercial LTE infrastructure and ecosystem 5

  11. 11. LTE Direct is a “Native” LTE solution Uses LTE Uplink Leverages LTE Infrastructure Proposed to be part of LTE Standard DL LTE Study item in Rel. 12 Timing, Configuration UL or LTE Authentication TDD LTE Communication Discovery LTE Direct Communication  For discovery and optionally also for  LTE network used for configuration and communication authentication  Communication can be either through network or direct device to device 11
  12. 12. Designed for autonomous “Always-ON” discoveryLow-overhead with extremely low battery consumption Discovery Short “wake-up” time LTE All devices synchronously “wake-up” for discovery LTE 20s 64ms Very high discovery capacity ■■■ E.g. Can discover 2816 services in 64msec ■■■ ■■■ ■■■ Highly scalable ■■■ Overhead scales with the capacity; ■■■ Easy to configure resources to suit demand Negligible LTE capacity impact • All devices either broadcast their needs/services or listen to others E.g. 0.3% reduction in uplink capacity for 2816 • Switch between broadcast and listen based on services/applications expressionsSource: Qualcomm simulations; Assumptions:10MHz bandwidth,64 discovery sub frames every 20s; Operator or some other entity has to manage a database of expressions and services they represent 12
  13. 13. Privacy sensitive, connectionless discovery Expression Expression - 1 Fast and Easy Friend Sea Sally @ Expressions are easy to read & Expression - 2 Finder Cafe decode, no connection needed Ticket Seller: 4:00 pm game seat 45B Finder Expression - 3 Devices in the proximity Anonymous read “Expressions” to determine Expression relevance Devices do not need to reveal their identity or location All devices broadcast 64 or 128 bit service identifier called “Expression” for each service they offerOperator or some other entity has to manage a database of expressions and services they represent ; Device to device contact needed for communication, but not for discovery 13
  14. 14. Unparalleled scalabilitySuperior discover capacity and latency than other device-to-device technologies LTE Direct WiFi Direct WiFi Direct Profile 1 Profile 2 Number of devices covered 7200 369 369 Active 0.64 119 82 Duration(s)Source – Qualcomm simulations; Assumptions: Outdoor dense deployment scenario (e.g Times Square); Ped A channel model, ITU-1411 NLOS model; Wi-Fi Direct – 10dB shadowing and 20dBwall penetration loss; BW - LTE Direct 10 MHz, Wi-Fi Direct – Synchronous operation with 20 MHz @ 5 GHz; 23dBm tx power, -5dB antenna gain, 7dB noise figure ; WiFi Direct Profile 1 – 100 % 14Service Discovery; WiFi Direct Profile 2 – 10 % Service Discovery;
  15. 15. Differentiated app/services enabled by proximatediscovery LTE Direct Discover Leash Trigger Search Social Matching - Geo-Fencing - Auto-Authentication- Query-Response - Friends/family Child, pet, elderly, etc. Proximity triggered User initiated and ad- discovery automation hoc Dwell Time - Push Advertising - Auto notification Loyalty Services - Hyper-relevant Autonomous ‘check-in’ notifications Credentialing - Qualify within a Gaming – Venue Services - boundary e.g. scavenger hunts, e.g. tourist bulletins, multi-payer games crime alerts 15
  16. 16. Next-Gen solution for emergency services Robust Cost-effective LTE Discovery UL or LTE TDD LTE Communication LTE Discovery Licensed spectrum ensures no interference & very-high reliability Utilizes commercial LTE network and spectrum Works even during extreme situations like Leverages huge LTE device ecosystem infrastructure failure Offers flexibility and customization to suit emergency Scalable to address small emergencies to services’ needs natural disasters 16
