Abstract: Non-text content may be exchanged in real time text (RTT) messages over a telecommunications network as part of an enhanced RTT (eRTT) service. A first UE can receive, from a second UE over a telecommunications network, capability information indicating whether the second UE is capable of exchanging text content and/or non-text content via RTT messages. Using this capability information, the first UE may determine whether to enable eRTT functionality on the first UE by determining whether to display a user interface element(s) in a selectable state on the display next to a RTT conversation window. The selectable user interface element(s), upon selection, allows a user of the first UE to create new non-text content, or select particular non-text content from available non-text content, for inclusion in a RTT message. The first UE may thereafter send non-text content in the RTT message to the second UE.

Abstract: An exemplary method provides for a user equipment (UE) receiving a first reference signal (RS) that was transmitted by a base station using a first transmit beam. The UE performs a first RS measurement with respect to the received first RS, producing a first measurement result.
