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.
