Abstract

Systems and methodologies are described that facilitate automatically configuring a network configuration parameter (e.g., cell size parameter, . . . ) in a wireless communication environment. Size of an area served by a cell associated with a base station can be detected automatically by the base station. For example, size of the area served by the cell can be detected based upon location information of UE(s) served by the cell, a path loss between the base station and the UE(s) served by the cell, and/or a transmit power level of a reference signal sent by the base station. Moreover, a value of a network configuration parameter (e.g., cell size parameter, . . . ) can be automatically assigned by the base station as a function of a comparison between the size of the area served by the cell and a set of thresholds. For instance, the set of thresholds can be configurable by a network operator.

First claim

What is claimed is:

1. A method that facilitates network configuration in a wireless communication environment, comprising:
receiving first information indicating a set of thresholds uniquely configured for a group of base stations, wherein the set of thresholds is configurable by a network operator;
receiving a feedback component from one or more user equipments (UEs) served by a base station, wherein the feedback component includes second information related to a path loss between the base station and the one or more UEs served by a cell associated with the base station;
using the feedback component to detect a size of an area served by the cell at the base station, wherein the group of base stations includes the base station; and
configuring an unconfigured cell size parameter at the cell with a value of a cell size as a function based upon comparing the size of the area served by the cell against the set of thresholds, wherein configuring the unconfigured cell size parameter is performed autonomously by the base station.

2. The method of claim 1 , wherein the set of thresholds includes a first threshold, a second threshold greater than the first threshold, and a third threshold greater than the second threshold.

3. The method of claim 2 , further comprising:
configuring the value of the unconfigured cell size parameter as very small when the size of the area served by the cell is less than or equal to the first threshold;
configuring the value of the unconfigured cell size parameter as small when the size of the area served by the cell is greater than the first threshold and the size of the area served by the cell is less than or equal to the second threshold;
configuring the value of the unconfigured cell size parameter as medium when the size of the area served by the cell is greater than the second threshold and the size of the area served by the cell is less than or equal to the third threshold; and
configuring the value of the unconfigured cell size parameter as large when the size of the area served by the cell is greater than the third threshold.

4. The method of claim 1 , wherein the value of the unconfigured cell size parameter is configured as being one of very small, small, medium, or large.

5. The method of claim 1 , wherein the value of the unconfigured cell size parameter is configured as being one of femto, pico, micro, or macro.

6. The method of claim 1 , further comprising signaling the value of the configured cell size parameter from the base station to a neighboring base station.

7. The method of claim 6 , further comprising signaling the value of the configured cell size parameter from the base station to the neighboring base station using an X2 application protocol (X2-AP).

8. The method of claim 6 , further comprising signaling the value of the configured cell size parameter from the base station to the neighboring base station via a core network using an S1 application protocol (S1-AP).

9. The method of claim 1 , wherein the feedback component further includes location information of the one or more UEs served by the cell.

10. The method of claim 9 , further comprising:
receiving the location information from the one or more UEs;
computing a set of distances from the base station to the one or more UEs based upon the location information;
generating a statistic based upon the set of distances; and
detecting the size of the area served by the cell as a function of the statistic based upon the set of distances.

11. The method of claim 10 , further comprising receiving the location information reported in measurement report messages (MRMs) from the one or more UEs.

12. The method of claim 10 , wherein the statistic based upon the set of distances is one or more of a maximum distance, a minimum distance, a mean distance, a median distance, an Rth largest distance where R is an integer, or S standard deviations from the mean distance where S is a real number.

13. The method of claim 1 , further comprising detecting the size of the area served by the cell as a function of a transmit power level of a reference signal sent by the base station.

14. The method of claim 1 , further comprising detecting the size of the area served by the cell as a function of two or more of location information of one or more UEs served by the cell, a path loss between the base station and the one or more UEs served by the cell, or a transmit power level of a reference signal sent by the base station.

15. A method that facilitates network configuration in a wireless communication environment, comprising:
receiving information specifying receive power levels of a reference signal from one or more user equipments (UEs);
generating a set of path losses from a base station to the one or more UEs by comparing a transmit power level of the reference signal to the receive power levels of the reference signal;
generating a statistic based upon the set of path losses;
detecting a size of an area served by a cell associated with the base station at the base station as a function of the statistic based upon the set of path losses between the base station and the one or more UEs served by the cell; and
assigning a value of a network configuration parameter as a function of the size of the area served by the cell at the base station.

16. The method of claim 15 , further comprising receiving the information specifying the receive power levels of the reference signal reported in measurement report messages (MRMs) from the one or more UEs.

17. The method of claim 15 , wherein the statistic based upon the set of path losses is one or more of a maximum path loss, a minimum path loss, a mean path loss, a median path loss, a Tth largest path loss where T is an integer, or U standard deviations from the mean path loss where U is a real number.
