Four UE Antennas – Implementation and Expectations

Carrier Aggregation, 256 QAM and now four downlink receive antennas – providing up to four parallel MIMO streams – are novel features in LTE, introduced by 3GPP to meet the demand of ever increasing data rates.

In this post we will discuss important aspects of migrating the User Equipment from two to four receive antennas in the downlink. We will explain the physical aspects, shed some light on certain important implementation issues, and identify the benefits, both from an operator’s and an end user’s perspective.
