Abstract

Methods and apparatus for multi-carrier, multi-cell wireless communication networks. A method for multi-carrier, multi-cell, OFDMA wireless communication system includes: generating cell-specific pilot subcarriers by base station, wherein the cell-specific pilot subcarriers include information related to specific cells, specific base stations or both of them, and the cell-specific pilot subcarriers are placed at a schedule frequency position in the base station signal; generating common pilot subcarriers by the base station, wherein the common pilot subcarriers include information related to at least a plurality of cells, the base stations and common to both of them, and the common pilot subcarriers are placed in the scheduled frequency position in the base station signal; and transmitting the base station signal.

Description

[0001] This application is claiming the benefit of U.S. Provisional Patent Application No. 60 / 540,032 filed on January 29, 2004, filed on January 20, 2005 and with application number 200580001222.4, and the title of the invention is "For multi-carrier, A divisional application of the Chinese patent application "Method and device for multi-cell wireless communication network". technical field [0002] The present application relates to the field of wireless communication, in particular, to a method and device for a multi-carrier, multi-cell wireless communication system. Background technique [0003] In multi-carrier wireless communication, such as figure 1 Many important system functions such as frequency synchronization and channel estimation are shown facilitated by using network information provided by a fraction of the total subcarriers, such as pilot subcarriers. The fidelity level of the received subcarriers dictates how well these functions can be implemented, which ...
