直交周波数分割多重アクセスにおけるセル固有の参照記号とユーザ装置固有の参照記号とを使用した復調方法、伝送方法、および基地局

Document Type and Number:

Japanese Patent JP5504459

Kind Code:

B2

Abstract:

A method, a network base station, and a user communication device for transmitting data on an orthogonal frequency-division multiple access system are disclosed. A network base station may have a common antenna set to transmit on a subcarrier via a first effective channel able to be constructed based on at least one common reference symbol. The network base station may have a dedicated antenna set to transmit on a subcarrier via a second effective channel able to be estimated based on at least one dedicated reference symbol. The user equipment may demodulate a data transmission using the at least one common reference symbol and the at least one dedicated reference symbol.
