Abstract

An apparatus configured for wirelessly communicating in a wireless communications network includes a wireless interface configured for wireless communication and a controller configured for controlling a beam pattern of the wireless interface and at least one communication parameter of the wireless interface. The apparatus is configured for receiving a locking signal indicating a request for locking at least a part of the beam pattern and the at least one communication parameter. The controller is configured for locking at least the part of the beam and the at least one communication parameter responsive to the locking signal.

First claim

The invention claimed is:

1. An apparatus configured for wirelessly communicating in a wireless communications network, the apparatus comprising:
a wireless interface configured for wireless communication; and
a controller configured for controlling a beam pattern of the wireless interface and at least one communication parameter of the wireless interface;
wherein the apparatus is configured for receiving a locking signal indicating a request for locking at least a part of the beam pattern and the at least one communication parameter; and
wherein the controller is configured for locking the part of the beam pattern and the at least one communication parameter responsive to the locking signal.

2. The apparatus of claim 1 , wherein the beam pattern is a sequence of individual and distinguishable beam patterns wherein for locking the part of the beam pattern and the at least one communication parameter the controller is configured for at least one of:
an order of the individual and distinguishable beam patterns within the sequence,
a duration of a static or dynamic activation,
a transition from an individual and distinguishable beam pattern into a consecutive individual and distinguishable beam pattern, and
a repetition cycles and/or durations;
as a specific beam pattern sequence to be repeated until an unlock signal is received and processed.

3. The apparatus of claim 1 , wherein the at least one communication parameter comprises one of a transmission power used for the beam pattern, a test or reference signal selection, a resource mapping used for transmission or reception with the part of the beam, a polarization used for transmission or reception with the part of the beam, a time resource, a frequency resource, a spatial resource, a code resource and a modulation coding scheme used for the wireless communication.

4. The apparatus of claim 1 , wherein the apparatus is configured for transmitting a response signal to respond to the locking signal.

5. The apparatus of claim 4 , wherein the apparatus is configured for generating the response signal to indicate an activation or deactivation of the locking the part of the beam pattern and/or the at least one communication parameter.

6. The apparatus of claim 4 , wherein the apparatus is configured for generating the response signal to indicate at least one of:
a lock of an analogue stage of a specific Rx beam complete,
lock of digital stage of a specific Rx beam complete,
lock of analogue and digital stage of a specific Rx beam complete,
lock of analogue stage of a specific Rx beam failed,
lock of analogue stage of a specific Tx beam complete,
lock of a specific Tx null complete,
lock of an analogue stage of a subset of a set of possible Rx beams complete,
unlock of digital stage of a specific Rx beam complete,
Activation/deactivation of a specific beam complete, and
Activation/deactivation of a repeated sequence of specific beam patterns to be repeated in a specified order, duration and/or transition phase/period.

7. The apparatus of claim 4 , wherein the apparatus is configured for generating the response signal to comprise a response on a query contained in the locking signal reporting a requested information.

8. The apparatus of claim 4 , wherein the apparatus is configured for reporting a success and/or a fail of the locking the part of the beam pattern and/or the at least one communication parameter with the response signal.

9. The apparatus of claim 8 , wherein the apparatus is configured for reporting a reason, why the apparatus failed or terminated the locking.

10. The apparatus of claim 1 , wherein the locking signal comprises information indicating an instruction to set the communication parameter to a value; wherein the apparatus is configured for adjusting the communication parameter to the indicated value and to lock the communication parameter at the indicated value.

11. The apparatus of claim 1 , wherein the apparatus is configured for forming the beam pattern for receiving a wireless reception signal and/or for transmitting a wireless transmission signal.

12. The apparatus of claim 1 , wherein the apparatus is configured for forming the beam pattern with the wireless interface, the beam pattern comprising at least a a first lobe, a second lobe, and a null;
wherein the controller is configured for locking at least one of the first lobe, the second lobe, and the null whilst remaining at least one of the first lobe, the second lobe and the null unlocked.

13. The apparatus of claim 1 , wherein the apparatus is configured for receiving an unlocking signal indicating a request for unlocking the at least one communication parameter;
wherein the controller is configured for unlocking the at least one communication parameter responsive to the unlocking signal.

14. The apparatus of claim 13 , wherein the controller is configured for unlocking the beam pattern responsive to the unlocking signal.

15. The apparatus of claim 1 , wherein the beam pattern comprises a plurality of lobes and/or a plurality of nulls between the lobes, wherein the apparatus is configured to time variably deactivate at least a first lobe or null during a first time interval and for deactivating at least a second lobe or null during a second time interval responsive to the locking signal.

16. The apparatus of claim 1 , wherein the locking signal comprises information indicating at least one of a plurality of lobes or one of a plurality of nulls of the beam pattern, wherein the apparatus is configured for locking the lobe or null indicated and for disabling at least one lobe or at least one null different from the indicated lobe or null responsive to the locking signal.

17. The apparatus of claim 1 , wherein the controller is configured for unlocking the at least one communication parameter after a time duration indicated by a duration information comprised by the locking signal.

18. The apparatus of claim 1 , wherein the apparatus is a User Equipment or a base station.

19. A method for testing an apparatus, the method comprising:
receiving, with the apparatus, a locking signal indicating a request for locking at least a part of a beam pattern formed by the apparatus and at least one communication parameter of the apparatus; and
locking the part of the beam pattern and the at least one communication parameter responsive to the locking signal.
