Study on further NR RedCap UE complexity reduction
This document captures the findings from the study item "Study on further NR RedCap UE complexity reduction" [2].
The study concerns potential solutions for reducing UE complexity further compared to the RedCap UE type introduced in Rel-17 [3], providing NR support for low-tier devices between existing LPWA UEs and Rel-17 RedCap UEs to further expand the market for RedCap use cases with relatively low cost, low energy consumption, and low data rate requirements, targeting 10 Mbps peak rate.
The study focuses on UE bandwidth reduction to 5 MHz and/or UE peak rate reduction to 10 Mbps, possibly in combination with relaxed UE processing timeline. The scope of the study includes support for FR1 bands for FDD and TDD and coexistence with Rel-15/16/17 UEs. The scope of the study does not include LPWA use cases.
