Abstract

A method of wireless communication is presented. The method includes determining, for each resource element group of a resource block pair, whether an interfering control channel is present on the resource block pair. The determination may be based on whether estimated power of the resource element groups varies among two or more resource element groups. The method also includes estimating the interference on the resource block pair based on the determination.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 61 / 676,797, filed July 27, 2012, entitled "INTERFERENCE ESTIMATION IN THE PRESENCE OF EPDCCH TRANSMISSIONS," under 35 U.S.C. §119(e), by reference The disclosure of which is expressly incorporated herein in its entirety. technical field [0003] In general, aspects of this disclosure relate to wireless communication systems, and more specifically, to estimating interference for resource block pairs based on the presence of an enhanced control channel. Background technique [0004] Wireless communication systems are widely deployed to provide various telecommunication services such as voice, video, data, messaging and broadcasting. Typical wireless communication systems may employ multiple-access techniques capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmission power). Exam...
