Embodiment Construction

[0048] 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.

[0049] As used in this application, the terms "component," "module," "system," and the like are intended to include computer-related entities that can be, but are not limited to, hardware, firmware, a combination of hardware and software, software, or an operating system. in the 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 / ...

Abstract

Systems and methodologies are described that facilitate supporting mobility for UEs and relay eNBs in split-cell relay configurations. Parameters regarding communicating with one or more UEs can be provided to disparate eNBs from a donor eNB to provide mobility for one or more of the UEs or a serving relay eNB. In addition, a donor eNB can request establishment of one or more radio bearers at a target relay eNB for continuing communications with one or more UEs. Moreover, a donor eNB can provide information regarding one or more core network bearers to a target donor eNB to facilitate establishing the core network bearers at the target donor eNB for communicating with the one or more UEs. Furthermore, uplink buffer contents from a relay eNB can be provided to a target donor eNB so communications from the one or more UEs can be continued by the target donor eNB.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This application for patent claims priority to Provisional Application No. 61 / 168,737, filed April 13, 2009, entitled "SPLIT-CELL BASED RELAYFOR LTE," which is assigned to the assignee of this application, and therefore It is 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 routing data packets among a plurality of access points. Background technique [0004] Wireless communication systems are widely deployed 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 capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power, . . . ). Examples of such multiple-access systems include Code Division Multiple Acces...
