17 Claims

1. An apparatus for a first access node, comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and computer program code being configured, with the at least one processor, to cause the apparatus to perform:

transmitting, to a second access node, a first message comprising at least one information element indicating activation status decision enablement for transmission legs configured to deliver duplicates of data packets from a terminal device;

depending on the activation status decision enablement, transmitting, to the terminal device, a second message comprising at least one information element indicating activation status of at least one transmission leg to deliver a duplicate of a data packet from the terminal device, wherein the activation status of the at least one transmission leg is decided by the first access node, wherein the activation status decision for the transmission legs is enabled for only those transmission legs established at the second access node; and

receiving, from the second access node, radio measurement data indicating quality of a radio channel of the transmission legs and deciding the activation status of the transmission legs on the basis of the radio measurement data.
