Embodiment Construction

[0041] 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 these aspects may be practiced without these specific details.

[0042] As further described herein, one or more parameters of a femto access point may be set or adjusted to suppress interference with one or more other access points (e.g., potentially caused by the communicating device). For example, a rise-over-thermal (RoT) threshold for a femtocell access point may be set based on one or more parameters associated with the access point in which the femtocell access point communicates and / or Adjustment. In one example, the one or more parameters can be path loss to a femtocell access point, one or more other femtocell access points, or a macrocell access point, among others. In another example, an esti...

Abstract

Methods and apparatuses are provided for determining one or more parameters of an access point that can be set or adjusted to mitigate interference to other access points. A rise-over-thermal (RoT) threshold can be set at an access point based on one or more parameters, such as pathloss measurements, location of the access point, etc., such that interference from devices communicating with the access point can be mitigated. In addition, a noise floor, RoT threshold, etc., can be adjusted based on determining a transmit power difference, out-of-cell interference, and / or similar measurements.

Description

[0001] This application is a divisional application of a Chinese patent application with a filing date of June 29, 2011, an application number of 201180032661.7, and a title of "Method and Device for Suppressing Interference in Femtocell Deployment". [0002] Claim priority based on 35 U.S.C § 119 [0003] This patent application claims priority to Provisional Application No. 61 / 359,762, entitled "ADAPTIVE RISE-OVER-THERMAL (ROT) THRESHOLD AND NOISE FLOOR ADJUSTMENT FOR FEMTOCELL UPLINK INTERFERENCE MANAGEMENT," filed June 29, 2010, which The provisional application has been assigned to the assignee of the present application and is hereby expressly incorporated by reference; and, this patent application claims the title "ADAPTIVE RISE-OVER-THERMAL (ROT)" filed on September 28, 2010 THRESHOLD AND NOISE FLOOR ADJUSTMENT FOR FEMTOCELL UPLINK INTERFERENCE MANAGEMENT" is the priority of provisional application No. 61 / 387,359, which is assigned to the assignee of the present applicat...
