Tata Elxsi today unveiled its 3GPP release 8 compliant LTE UE (user equipment) protocol stack.

The new solution promises to provide complete software for Layer 2 and Layer 3, including MAC, RLC, PDCP, RRC and NAS in addition to also featuring optional LTE specific components such as RoHC v1/v2, Snow-3G, AES and Layer 1 algorithms.

Technically the architecture of the UE software is split into control plane and data plane to handle critical and non-time critical operations, meeting the high throughput demands of LTE UE, says the company. Tata Elxsi further adds that the solution has been modularly architected for SoC implementation, and is agnostic to the underlying Operating System and hardware.

Furthermore, the solution also features a multi-mode controller with intelligence for inter/intra Radio Access Technology (RAT) handover to enable backward compatibility to 3G. The solution has been integrated on an embedded platform and is ready for interop-testing with eNodeB solutions, ensuring optimum implementation and maturity, claims Tata Elxsi.

According to the company, the solution features comprehensive debug trace and statistical logging capabilities, and the descriptor-based MAC-PHY Interface enables easy adaptation of Tata Elxsi L2/L3 solution to third party L1 implementations.

“We have leveraged our deep expertise in the development, integration, interop and compliance testing for CDMA, WiMAX and 3G based CPE and handset solutions, to deliver an industry-leading software solution for LTE terminal devices”, says Nitin Pai, Vice President, Marketing, Tata Elxsi.
