Embodiment Construction

[0027] 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 can be evident, however, that these aspects can be practiced without the use of these specific details.

[0028]As used in this application, the terms "component," "module," "system," and the like are intended to include a computer-related entity that can be, but is not limited to, hardware, firmware, a combination of hardware and software, software, or running 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. As examples, both an application running on a computing device and a computing device can be a component. One or more components can reside within a process and / or thread of execution...

Abstract

Systems and methodologies are described that facilitate assigning uplink resources for utilization by a mobile device for sending an uplink signal in an uplink coordinated multi-point (CoMP) wireless communication environment. For instance, a hopping tree can be defined across base stations, and neighboring base stations can schedule interfering mobile devices upon uplink resources mapped to different nodes from the hopping tree. By way of another example, a plurality of hopping trees can be employed across base stations in the uplink CoMP wireless communication environment. Moreover, an acknowledgment can be sent to the mobile device upon downlink resources identified as a function of the uplink resources. Further, the downlink resources can be distinct from disparate downlink resources utilized for sending an acknowledgment to a disparate mobile device from a neighboring base station.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This patent application claims priority to Provisional Application No. 61 / 120,659, filed December 8, 2008, entitled "OPTIMIZATIONS TO SUPPORT UPLINK NETWORK MIMO IN LTE," which is assigned to the assignee of this application , which is hereby expressly incorporated herein by reference. technical field [0003] In general, the following description relates to wireless communications, and in particular, the following description relates to implementing optimizations to support uplink coordinated multipoint (CoMP) in a wireless communications environment. Background technique [0004] Wireless communication systems are widely deployed today to provide various types of communication content such as voice, data, and so on. A typical wireless communication system may be a multiple-access system that supports communication with multiple users by sharing available system resources (eg, bandwidth, transmit power, . . . ). Ex...
