LTE UE category | UE category in LTE cat-1, 2, 3, 4, 5

This page covers LTE UE category including PHY layer parameters. It covers UE category in LTE viz. cat-1, cat-2, cat-3, cat-4 and cat-5.

The LTE UE downlink and uplink PHY layer parameters such as buffer sizes, modulation type, data rate (Mbps), MIMO, max. MCH bits, DL-SCH transport block size etc. are mentioned for different LTE UE categories in the table below.
