Abstract

A method for operating a wireless communication network, wherein a first member of the network transmits a scheduling message to a secondary member of the network and the secondary member receives the scheduling message. The secondary member 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 sounding signal schedule and/or the schedule message refers to a compact schedule of sounding signals.

First claim

What is claimed is:

1. A method for operating a wireless communication network, wherein:
a first node of the network transmits a scheduling message to a second node of the network;
the second node receives the scheduling message; and
the second node schedules sounding signal transmissions based on the scheduling message;
wherein the scheduling message refers to a schedule for sounding signals based on a status of beam forming performed in the network and indicates a sounding signal pattern fitting within one subframe.

2. The method of claim 1 , wherein the schedule of sounding signals is based upon the shape and/or sweeping trajectory of a beam formed by the first node and/or the second node.

3. The method of claim 1 , wherein the schedule provides and/or schedules sounding signals covering at least 50% of the sub bands and/or resource blocks of the bandwidth or carrier within the one subframe.

4. The method of claim 1 , wherein the schedule schedules the sounding signal pattern repeatedly over the one subframe.

5. The method of claim 1 , wherein the schedule provides scheduling of Physical Uplink Shared Channel (PUSCH) signals.

6. 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 indicates a sounding signal pattern fitting within one subframe.

7. The method of claim 6 , wherein the schedule of sounding signals is based upon the shape and/or sweeping trajectory of a beam formed by the first node and/or the second node.

8. The method of claim 6 , wherein the schedule provides and/or schedules sounding signals covering at least 50% of the sub bands and/or resource blocks of the bandwidth or carrier within the one subframe.

9. The method of claim 6 , wherein the schedule schedules the sounding signal pattern repeatedly over the one subframe.

10. The method of claim 6 , wherein the schedule provides scheduling of Physical Uplink Shared Channel (PUSCH) signals.

11. 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 based on the scheduling message; wherein the scheduling message refers to a schedule for sounding signals based on a status of beam forming performed in the network and indicates a sounding signal pattern fitting within one subframe.

12. The method of claim 11 , wherein the schedule of sounding signals is based upon the shape and/or sweeping trajectory of a beam formed by the first node and/or the second node.

13. The method of claim 11 , wherein the schedule provides and/or schedules sounding signals covering at least 50% of the sub bands and/or resource blocks of the bandwidth or carrier within the one subframe.

14. The method of claim 11 , wherein the schedule schedules the sounding signal pattern repeatedly over the one subframe.

15. The method of claim 11 , wherein the schedule provides scheduling of Physical Uplink Shared Channel (PUSCH) signals.

16. A first node for a wireless communication network, the first node comprising:
radio circuitry; and
control circuitry operatively coupled to the radio circuitry and configured to control the radio circuitry to transmit a scheduling message for a second node;

wherein the scheduling message refers to a schedule for sounding signals based on a status of beam forming performed in the network and indicates a sounding signal pattern fitting within one subframe.

17. A second node for a wireless communication network, the second node comprising:
radio circuitry; and
control circuitry operatively coupled to the radio circuitry and configured to control the radio circuitry to receive a scheduling message from a first node and further configured to schedule sounding signal transmissions based on the scheduling message;

wherein the scheduling message refers to a schedule for sounding signals based on a status of beam forming performed in the network and indicates a sounding signal pattern fitting within one subframe.
