Abstract
An extended power class for Uplink (UL) Multiple Input Multiple Output (MIMO) communications is provided. In this regard, a User Equipment (UE) configured to UL MIMO can indicate support for a first power class corresponding to a first power level. The UE can transmit a single layer Physical UL Shared Channel (PUSCH) on one antenna port at a power that is at most a first power level corresponding to the first power class. The UE can also transmit an N-layer PUSCH on N antenna ports at a second power level greater than the first power level. With the extended power class, UEs are able to deliver higher power signals without increasing the maximum power of their Power Amplifiers (PAs). This greater power can lead to better user experience, less battery drain, and higher network capacity.
