    摘要: In one embodiment, a transmitter includes a binary sequence generator unit configured to provide a sequence of reference signal bits, wherein the sequence is an inseparable function of a cell identification parameter, a cyclic prefix mode corresponding to the transmitter and one or more time indices of the sequence. The transmitter also include a mapping unit that transforms the sequence of reference signal bits into a complex reference signal, and a transmit unit configured to transmit the complex reference signal. In another embodiment, a receiver includes a receive unit configured to receive a complex reference signal and a reference signal decoder unit configured to detect a sequence of reference signal bits from the complex reference signal, wherein the sequence is an inseparable function of a cell identification parameter, a cyclic prefix mode corresponding to a transmitter and one or more time indices of the sequence.

    摘要: This invention concerns multiplexing in Long Term Evolution (LTE) and Long Term Evolution-Advanced (LTE-A) in Evolved Universal Terrestrial Radio Access Network (E-UTRAN) wireless telephony. Joint processing down link coordinated multi-point reference signaling includes combining resource signal types at a user equipment, determining conflicts between resource signals of plural user equipment, puncturing resource signals of other cell upon determining conflicts between resource signals of plural user equipment and transmitting non-punctured combined resource signals from a user equipment.
