Embodiment Construction

[0044] 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.

[0045] As used in this application, the terms "component," "module," "system," and the like are intended to refer to 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 executio...

Abstract

Systems and methodologies are described that facilitate compressing packet headers for cell relay communications. Since cell relays can support a number of evolved packet system (EPS) bearers over a given dedicated radio bearer (DRB), robust header compression (RoHC) can be multiplexed for communications to/from a given cell relay. Thus, an upstream node compressing one or more packet headers can indicate a RoHC context, which can be represented by a RoHC context identifier in a RoHC header. A receiving entity can decompress the headers based on determining the RoHC context. Alternatively, the RoHC context can be associated with an identifier of a related UE bearer such as a tunnel endpoint identifier (TEID), a relay identifier, and/or the like, that is received in a tunneling protocol header to facilitate packet routing.

Description

[0001] Claiming Priority Based on 35 U.S.C. §119 [0002] This application for patent claims the benefit of Provisional Application No. 61 / 108,287, filed October 24, 2008, entitled "CELL RELAY BASE STATION FOR LTE," which is assigned to the assignee of this application, so 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 compressing protocol headers in communications using cell relays. 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, . . . ). Examples of such multiple-access systems include Code Division Multiple A...
