What is LTE direct and is there any functional difference between LTE and LTE direct?

Question

Like we have in UMTS, on the same lines do we have any direct relation between the LTE UL RSSI and UL load ?

Answer 1

LTE Direct is a new and innovative device-to-device technology being standardized in 3GPP-R12. By using this feature, one user can broadcast its information in 128-bit long expression and another user can read this information based on his/her interest.

It enables "always-on" discovery of thousands of devices and their services in a proximity of 500m, in a privacy sensitive and battery efficient way.

LTE Direct relies on the LTE physical layer to provide a scalable and universal framework for discovery and connection. It works seamlessly with LTE: Subframes are set aside for discovery; resources are time synced with geography.

LTE Direct is also a distributed networking protocol: No cell tower is needed for communication between adjacent & peer-connected devices. It allows multi-hop communication with very little battery use as compared to WiFi Direct. LTE Direct is a mesh network & is sometimes referred to as D2D (Device-2-device). It is designed with spectral efficiency in mind & aims to reduce congestion, dead zones & battery use on compliant 4G LTE-A devices.
