Embodiment Construction

[0035] It should be noted that one or more specifications (e.g., 3rd Generation Partnership Project (3GPP) Release 8 (Rel-8), 3GPP Release 9 (Rel-9), 3GPP Release 10 (Rel-10) , Long Term Evolution (LTE), LTE-Advanced (LTE-A), etc.) to describe the systems and methods disclosed herein. However, at least some of the concepts described herein may be applicable to other wireless communication systems. For example, the term user equipment (UE) may be used to refer to the more general term "wireless communication device." Furthermore, one or more of the terms Node B, evolved Node B (eNB), Home evolved Node B (HeNB), etc. may be used to refer to the more general term "base station."

[0036] As used herein, the term "base station" generally refers to a communications device capable of providing access to a communications network. Examples of communication networks include, but are not limited to: telephone networks (e.g., "landline" networks such as the public switched telephone ne...

Abstract

A base station for enabling communication with a high-mobility wireless communication device is described. The base station includes a processor and instructions stored in memory. The base station identifies a high-mobility wireless communication device and sends a reference signal configuration. The base station also allocates an additional specific reference signal and sends the additional specific reference signal to the high-mobility wireless communication device.

Description

[0001] related application [0002] This application is related to, and claims priority from, US Provisional Patent Application No. 61 / 259,561, filed November 9, 2009, entitled "ENHANCED UE-RS DESIGN FOR HIGH MOBILITY UEs IN LTE-A." technical field [0003] In general terms, the present invention relates to electronic communications. In particular, the present invention relates to reference signaling for high mobility wireless communication devices. Background technique [0004] In recent decades, the use of electronic devices has become widespread. In particular, advances in electronics technology have reduced the cost of increasingly complex and useful electronic devices. Cost reductions and consumer demands have led to a rapid increase in the use of electronic devices, making them nearly ubiquitous in modern society. As the use of electronic devices increases, so does the demand for new and improved features of electronic devices. Specifically, people generally seek e...
