Abstract

Embodiments disclosed herein provide systems and methods to provide relay operation information to a wireless communication network. In a particular embodiment, a method provides determining information regarding operation of a wireless communication relay and transferring the information to a Long Term Evolution (LTE) wireless communication network. The method further provides, based on the information, adjusting parameters for LTE communication paths that pass through the wireless communication relay.

Claims

1. A method of operating a Long Term Evolution (LTE) communication system, comprising:

a wireless communication relay determining a number of transmit paths, a number of receive paths, and an azimuth of the wireless communication relay and-transferring the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay to an LTE eNodeB;

the LTE eNodeB selecting a modulation coding scheme and a rank index for LTE communication paths that pass through the wireless communication relay based on the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay; and

the LTE eNodeB exchanging communications on the LTE communication paths through the wireless communication relay using the selected modulation coding scheme and the rank index.

2. The method of claim 1, wherein transferring the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay comprises transferring the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay when the wireless communication relay registers with the LTE wireless communication network.

3. The method of claim 1 further comprising updating a coverage area for the wireless communication relay based on the azimuth.

4. The method of claim 1 further comprising:

the wireless relay determining and transferring Effective Isotropically Radiated Power (EIRP) of the wireless communication relay to the LTE eNodeB; and

the LTE eNodeB updating a coverage area for the wireless communication relay based on the EIRP.

5. A Long Term Evolution (LTE) communication system, comprising:

a wireless communication relay configured to determine a number of transmit paths, a number of receive paths, and an azimuth of the wireless communication relay and transfer the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay to an LTE eNodeB;

the LTE eNodeB configured to select a modulation coding scheme and a rank index for LTE communication paths that pass through the wireless communication relay based on the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay; and

the LTE eNodeB configured to exchange communications on the LTE communication paths through the wireless communication relay using the selected modulation coding scheme and the rank index.

6. The method of claim 5, wherein the wireless communication relay configured to transfer the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay comprises transferring the number of transmit paths, the number of receive paths, and the azimuth of the wireless communication relay when the wireless communication relay registers with the LTE wireless communication network.

7. The method of claim 5 further comprising the LTE eNodeB configured to update a coverage area for the wireless communication relay based on the azimuth.

8. The method of claim 5 further comprising:

the wireless communication relay configured to determine and transfer Effective Isotropically Radiated Power (EIRP) of the wireless communication relay to the LTE eNodeB; and

the LTE eNodeB configured to update a coverage area for the wireless communication relay based on the EIRP.
