|1. An apparatus comprising:
a transmitter configured to transmit encoded multimedia data during a session over a wireless communication channel; and
a transmit (Tx) Quality of Experience (QoE) estimator configured to determine at least one Tx QoE indicator corresponding
to the session, and to provide the at least one Tx QoE indicator to a session manager of the session, the Tx QoE estimator
configured to determine the at least one Tx QoE indicator based at least on a transmit-side mean opinion score (Tx MOS) corresponding
to the encoded multimedia data, and a channel quality parameter corresponding to the wireless communication channel, the at
least one Tx QoE indicator comprising a first Tx QoE indicator relative to a first threshold, and a second Tx QoE indicator
relative to a second threshold, the second threshold higher her than the first threshold.
