WP1 (D2D/Relay interface)
Design D2D interface between a modem LTE handset and a test mobile equipment to acquire location information of the user that is out of range from the control centre. Design relay communication between the control centre and the out-of-range mobile user via an in-range user acting as a relay.
Tasks in this WP include:
- T1) (Months 1-5 or M1-5) – Investigate relaying schemes (amplify-and-forward, decode-and-forward, two-way relay) in the new context of delivery of location and safety/emergency data only;
- T2) (M3-10) – Develop beacon signal, proximity device discovery, and tracking algorithms on LTE D2D mobile devices; and
- T3) (M8-16) – Design multiple access algorithms when a commercial LTE mobile device acts as a relay solely for emergency/safety purpose (short messages with very low latency)
WP2 (Suite of software, database and protocol)
Develop a protocol and autonomous intelligent software/database at the control centre to monitor, collect and analyse location information of mobile users via the physical D2D/relay links and then automatically dispatch relevant safety/emergency messages to the users.
- T4) (M1-8) – Develop autonomous intelligent software and location database at the control centre that is able to analyse critical location data and convert it into safety/emergency messages;
- T5) (M4-11) – Develop a protocol for new type of communication between control centre and relay for safety/emergency communication; and
- T6) (M10-16) – Develop an app at the LTE D2D-enabled mobile device to automatically update location information when engaged in D2D communication with another mobile device within proximity
WP3 (Final integration, validation and testing)
- T7) (M15-24) – Integrate, validate and test all designs in the two above WPs as the whole system and as a demo model; and
- T8) (M23-24) – Writing up
