Abstract
A UE may determine a number of antenna ports associated with a frequency band that includes one or more CCs. The determined number of antenna ports may be based on a plurality of UL Tx chains for the one or more CCs/frequency band. The UE may switch from a first UL Tx chain to a second UL Tx chain, at least one of which may be associated with the one or more CCs/frequency band. The number of antenna ports may correspond to a maximum number of antenna ports of an individual CC of the one or more CCs, or to a sum of antenna ports of the one or more CCs. For the latter, the number of antenna ports may be limited to an available number of UE antenna ports when the sum of antenna ports is greater than the available number of UE antenna ports.
