Abstract

A method of wireless communication includes configuring a virtual SRS (sounding reference signal) transmission to prompt user equipment (UE) to use a shortened uplink transmission format to create a silent period at an end of subframe. Reports are received from the UE indicating interference observed during the silent period.

Description

[0001] This application claims U.S. Serial No. 61 / 324,705 filed on April 15, 2010, entitled "COORDINATED SILENT PERIOD WITH SOUNDING REFERENCE SIGNAL (SRS) CONFIGURATION IN ADVANCED LONG TERM EVOLUTION (LTE-A) NETWORKS" Provisional Patent Application for the benefit of all, the disclosure of which is expressly incorporated herein by reference in its entirety. technical field [0002] In general, aspects of the present disclosure relate to wireless communication systems, and in particular, to uplink quiet period based interference management. Background technique [0003] Wireless communication networks are widely deployed to provide various types of 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 Divis...
