However, such power calibration is not necessarily sufficient to operate a low power base station in a desired manner, such as to provide a desired coverage area within the boundaries of an area (eg, within the walls or ground of a residence or office, etc.) , since it only considers the potential interference to other nodes or devices

Embodiment Construction

[0037] Various aspects are now described with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspects may be practiced without these specific details.

[0038] As described further herein, a low power base station or femto node may calibrate transmit power based at least in part on one or more aspects related to user equipment (UE) served by the femto node. For example, a femto node may determine or otherwise infer a usage pattern of one or more UEs at the femto node to detect coverage-unreachable areas in a building associated with the femto node. A femto node may calibrate its transmit power in an attempt to cover such an area. The region can be inferred based in part on observing representative parameters. In one example, a femto node can apply short-term power adjustments at least for pil...

Abstract

Methods and apparatuses are provided that include calibrating transmit power of a femto node based on measuring one or more parameters related to usage of the femto node. The femto node can temporarily increase transmit power and analyze received measurement reports to determine a transmit power calibration. The femto node can additionally measure uplink received signal strength indicators over multiple time periods following handover of a user equipment (UE) to determine whether to increase transmit power to cover the UE.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 477,945, filed April 21, 2011, entitled "METHOD AND APPARATUS FOR ESTIMATING HOME USER USAGE AT FEMTOCELLS," which is assigned to the Assignee, it is hereby expressly incorporated by reference. technical field [0003] In general, the following description relates to wireless network communications, and in particular, the following description relates to determining usage at a femto node. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as, for example, voice, data, and so on. A typical wireless communication system may be a multiple-access system capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power, ...). Examples of such multiple-access systems may include Code Division Multiple Access...
