Embodiment Construction

[0036] Various aspects are now described with reference to the figures. In the following description, for purposes of explanation, numerous specific details are given 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.

[0037] As used in this application, the terms "component", "module", "system" and the like are intended to refer to a computer-related entity such as, but not limited to, hardware, firmware, a combination of hardware and software, software, or an executing software. 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. For example, both an application program running on a computing device and the computing device can be a component. One or more components can reside within a process and / or thread of execution, and ...

Abstract

Systems and methodologies are described that facilitate identifying resources upon which an acknowledgment can be sent or received in a wireless communication environment that leverages coordinated multi-point (CoMP). The resources can be identified based upon a criterion that can be identifiable to a non-anchor cell base station (as well as an anchor cell base station, a mobile device, etc.). The criterion can be an identifier corresponding to a mobile device, where the identifier maps to a predetermined set of resources. Examples of the identifier can include a media access control identifier (MACID), a cell radio network temporary identifier (C-RNTI), a short C-RNTI, etc. Further, the criterion can be physical resources corresponding to a transmission, where the acknowledgment is responsive to the transmission. Moreover, the acknowledgment can be sent or received in connection with a cooperation technique (e.g., joint transmission via inter-site packet sharing, cooperative beamforming, cooperative silence, ).

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This application for patent claims the benefit of Provisional Application No. 61 / 108,302, filed October 24, 2008, entitled "C-RNTI BASED ACK FOR SOFT HANDOFF AND N-MIMO IN OFDMA," which is assigned to this application assignee and is hereby expressly incorporated by reference. technical field [0003] The following description relates generally to wireless communications, and more specifically to identifying, based on criteria recognizable by anchor cell base stations and non-anchor cell base stations, that can be used to send or receive acknowledgment (ACK) in a wireless communication environment utilizing coordinated multipoint (CoMP). )Resources. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content, eg, voice, data, and so on. A typical wireless communication system may be a multiple-access system capable of supporting communication wit...
