Abstract

Apparatuses, methods, and systems of a hybrid node are disclosed. One embodiment of the hybrid node includes a first sector and a second sector. The first sector is operative to transmit a signal through a predetermined transmission channel at each of a first plurality of transmit beam forming settings. The second sector is operative to receive the signal through the predetermined channel at a second plurality of receive beam forming settings for each of more than one of the first plurality of transmit beam forming settings. Further, the node is operative to measure a received signal quality of the received signal at each of the second plurality of receive beam forming settings of the second plurality of antenna elements, for each of the more than one of the first plurality of transmit beam forming settings of the first plurality of antenna elements.

Claims20

Dependent claims

A method, comprising:

selecting, by a cloud controller, a first plurality of transmit beam forming settings of a first plurality of antenna elements of a first sector of an access node;
selecting, by the cloud controller, a second plurality of receive beam forming settings of a second plurality of antenna elements of a second sector of the access node;
characterizing the access node, by the cloud controller, comprising the cloud controller instructing the access node to:
transmit, by the first plurality of antenna elements of the first sector of the access node, a signal through a predetermined transmission channel at each of the first plurality of transmit beam forming settings of the first plurality of antenna elements;
and
receive, by a second plurality of antenna elements of a second sector of the access node, the signal through the predetermined channel at a second plurality of receive beam forming settings of the second plurality of antenna elements, for each of more than one of the first plurality of transmit beam forming settings of the first plurality of antenna elements.
