Problems solved by technology

On the downlink, a data transmission from a base station may observe interference due to, for example, data transmissions from neighboring base stations
On the uplink, a data transmission from a UE may observe interference due to, for example, data transmissions from other UEs communicating with neighbor base stations
For both downlink and uplink, interference due to interfering network entities such as base stations and / or UEs can degrade performance

Embodiment Construction

[0034] Various aspects are now described with reference to the figures. 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.

[0035] As used in this application, the terms "component", "module", "system" and the like are intended to include computer-related entities such as, but not limited to, hardware, firmware, a combination of hardware and software, software, or software in execution . For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and / or a computer. By way of illustration, both an application running on a computing device and the computing device can be components. One or more components can reside within a process and / or thread of execution...

Abstract

Certain aspects of the invention provide methods, apparatus and computer program products for detecting potentially interfering user equipment (UE) or interfering UEs in the vicinity of a detecting entity. The detection entity may be a base station or a UE. In one aspect, the proposed detection scheme uses semi-static system information from one or more neighboring base stations (BSs) and identifies UEs of neighboring BSs causing interference in the physical uplink control channel (PUCCH). The proposed detection scheme can also identify the corresponding resources assigned by the interfering neighbor base station to the interfering UE. In some aspects, a detection scheme may not use information from one or more neighboring BSs.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to U.S. Provisional Application No. 61 / 556,783, filed November 7, 2011, entitled "Method and Apparatus for Proximity Detection," which provisional application has been assigned to the assignee of the present application, and therefore It is expressly incorporated herein by reference. technical field [0003] The present invention relates generally to wireless communications, and more particularly to detecting and / or managing interference in wireless networks. Background technique [0004] Wireless communication networks are widely deployed to provide various communication content such as voice, video, packet data, messaging, broadcast, and so on. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing available network resources. Examples of such multiple-access networks include Code Division Multiple Access (CDMA) networks, Time...
