Method and Apparatuses for Operating a Wireless Communication Network

A method for operating a first node in a wireless communication network, wherein:

• the first node transmits a scheduling message for a second node of the network, wherein the scheduling message refers to a schedule for sounding signals based on a status of beam forming performed in the network and/or wherein the scheduling message refers to a compact schedule for sounding signals.

A method for operating a second node in a wireless communication network, wherein:

• the second node receives a scheduling message from a first node;
• and the second node schedules sounding signal transmissions and/or a corresponding schedule based on the scheduling message;
• wherein the scheduling message and/or the sounding signal schedule refers to a schedule for sounding signals based on a status of beam forming performed in the network and/or wherein the scheduling message and/or schedule refers to a compact schedule for sounding signals.

A first node for a wireless communication network, the first node being adapted for transmitting a scheduling message for a second node;

• wherein the scheduling message and/or the sounding signal schedule refers to a schedule for sounding signals based on a status of beam forming performed in the network and/or wherein the scheduling message refers to a compact schedule for sounding signals.

A second node for a wireless communication network, the second node being adapted to receive a scheduling message from a first node;

• and further being adapted to schedule sounding signal transmissions and/or a corresponding schedule based on the scheduling message;
• wherein the scheduling message and/or the sounding signal schedule refers to a schedule for sounding signals based on a status of beam forming performed in the network and/or wherein the scheduling message refers to a compact schedule for sounding signals.
