Control mechanism for supporting connection establishment procedure

An apparatus for use by a communication element or function configured to conduct a communication in a communication network under control of a communication network control element or function, the apparatus comprising

• at least one processing circuitry;
• and
• at least one memory for storing instructions to be executed by the processing circuitry;
• wherein the at least one memory and the instructions are configured to, with the at least one processing circuitry, cause the apparatus at least to:
• obtain information for conducting measurements for establishing a secondary connection during a random access procedure conducted for establishing a primary connection, wherein the measurements for establishing the secondary connection are to be based on a reference signal to be transmitted by at least one secondary communication network control element or function enabling the establishment of the secondary connection,
• start a random access procedure for establishing the primary connection with the communication network control element or function by sending a random access related signaling to the communication network control element or function,
• determine a timing for receiving the reference signal from the at least one secondary communication network control element or function on the basis of the obtained information, and
• listen to the reference signal transmitted by the at least one secondary communication network control element or function on based upon the determined timing.

A method for use in a communication network control element or function configured to conduct a communication control for a communication with a communication element or function in a communication network, the method comprising:

• preparing the communication element or function to conduct measurements for establishing a secondary connection during a random access procedure conducted for establishing a primary connection, wherein the measurements for establishing the secondary connection are to be based on a reference signal to be transmitted by at least one secondary communication network control element or function enabling the establishment of the secondary connection;
• receiving and processing a random access related signaling from the communication element or function regarding the primary connection;
• determining a timing for initiating a transmission of the reference signal by the at least one secondary communication network control element or function;
• and
• causing transmission of the reference signal by the at least one secondary communication network control element or function on the basis of the determined timing.
