Abstract: A method and apparatus for transmitting/receiving reference signals in Long Term Evolution (LTE) and LTE-Advanced (LTE-A) systems includes determining whether a dedicated reference signal is detected in a current subframe; estimating, if a dedicated reference signal is detected in the current subframe, a data channel using the dedicated reference signal to receive data; and estimating, if no dedicated reference signal is detected in the current subframe, a data channel using a common reference signal detected in the current subframe to receive data. The transmission scheme uses a DeModulation Reference Signal (DM-RS) for channel response estimation. To secure backward compatibility of the LTE-A system, a Common Reference Signal is transmitted in normal subframes.

Abstract: In legacy systems such as 3rd Generation Partnership Project (3GPP) releases 8 to 10, the control channel is transmitted using the first few Orthogonal Frequency Division Multiplexing (OFDM) symbols in a subframe. The limited control channel capacity will impact the system performance in future releases as more and more User Equipments (UEs) will be scheduled in a subframe with technologies such as MulitUser-Multiple Input Multiple Output (MU-MIMO) and Coordinated Multipoint (CoMP) transmission being enhanced or introduced. A new Enhanced Control CHannel (E-CCH) is necessary to be designed, which will use the resource in the Physical Downlink Shared CHannel (PDSCH) in the legacy systems. The E-CCH will support UE-specific DeModulation Reference Signal (DMRS) based transmission and receiving. However, the configuration of DMRS for E-CCH is necessary to be known to UE in prior. This invention discloses multiple methods in which DMRS is configured for E-CCHs and respective eNB and UE behaviors.

Abstract translation: 在诸如第3代合作伙伴计划（3GPP）版本8至10的遗留系统中，使用子帧中的前几个正交频分复用（OFDM）符号来发送控制信道。 由于随着越来越多的用户设备（UE）将在诸如多媒体多输入多输出（MU-MIMO）和协调多点（CoMP）传输等技术的子帧中进行调度，有限的控制信道容量将影响未来版本中的系统性能 被强化或引入。 需要设计新的增强型控制信道（E-CCH），这将使用传统系统中物理下行链路共享信道（PDSCH）中的资源。 E-CCH将支持基于UE特定的调制参考信号（DMRS）的传输和接收。 然而，对于E-CCH的DMRS的配置在UE之前是必需的。 本发明公开了多种方法，其中DMRS被配置用于E-CCH以及相应的eNB和UE行为。
