Abstract

The present application relates to devices and components including apparatus, systems, and methods to perform SRS transmission when a UE supports SRS Tx antenna port switching. In an example, a determination is made about whether a scheduled SRS transmission impacts a scheduled DL reception given the SRS Tx antenna port switching. If so, the SRS transmission and/or the DL reception are changed. In a further example, the UE can supports an SRS TA capability in conjunction with the SRS Tx antenna port switching capability. In this example, SRS TA can be applied to a scheduled SRS transmission.
