Method and system for self-organizing networks using cooperative sensing
View Patent ↗A method, network element and user equipment, where in one embodiment at a network element within a secondary cell for self-optimizing operation with a primary cell, the method transmitting using an initial transmit power from the network element; requesting feedback from sensors located near a location; receiving the feedback from the sensors; and adjusting a transmit power based on the received feedback.
1. A method at a network element within a secondary cell for self-optimizing operation with a primary cell, the method comprising:
transmitting using an initial transmit power from the network element within the secondary cell;
requesting feedback from sensors of sensing measurements of transmissions received from the network element, the sensors located near a location in a region correlated with the primary cell;
receiving the feedback from the sensors; and
adjusting a transmit power of the network element based on the received feedback.
2. The method of claim 1 , wherein the initial transmit power is provided by at least one of a network, spectrum management entity or radio resource management entity.
3. The method of claim 1 , wherein the location is a reference point in or about the primary cell.
4. The method of claim 1 , wherein the location is a reference point in or about the secondary cell.
5. The method of claim 1 , wherein the feedback received is weighted based on a distance from the sensing user equipment to the location.
6. The method of claim 1 , wherein the feedback received is weighted by a confidence value assigned to the sensor.
7. The method of claim 6 , wherein the confidence value is based on a correlation of signal to interference noise ratio measurements between sensors and a reference user equipment in the location.
8. The method of claim 6 , wherein the confidence value is based on a pass loss between the sensor and the secondary cell.
9. The method of claim 1 , wherein the adjusting is iterative based on further received feedback.
10. The method of claim 1 , wherein the secondary cell is selected based on a proximity to the primary cell.
11. The method of claim 1 , wherein the receiving is over an analogue feedback channel.
12. A network element within a secondary cell for self-optimizing operation with a primary cell, the network element comprising:
a processor; and
a communications subsystem,
wherein the network element is configured to:
transmit within the secondary cell using an initial transmit power from the network element;
request feedback from sensors of sensing measurements of transmissions received from the network element, the sensors located near a location in a region correlated with the primary cell;
receive the feedback from the sensors; and
adjust a transmit power of the network element based on the received feedback.
