Abstract

A method of wireless communication includes detecting uplink interference in a received uplink transmission of a user equipment. The received uplink transmission is padded with noise based on the detected interference and also based on a frequency domain partition, whether a subframe is protected, and / or a user equipment type.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application 61 / 323,855, filed April 13, 2010, entitled "NOISE PADDING TECHNIQUES IN HETEROGENEOUS NETWORKS (HETNET)," which is hereby expressly incorporated by reference The entire disclosure is incorporated herein. technical field [0003] In general, aspects of the present disclosure relate to wireless communication systems, and more particularly, to noise filling techniques in heterogeneous wireless communication networks. Background technique [0004] Wireless communication networks are widely deployed to provide various communication services 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 Division Multi...
