Abstract: Systems, base stations, terminals, and methods for group-selective channel feedback in a wireless communication system are described. In one signal measurement method for a base station supporting Multiuser Multiple-Input Multiple-Output (MU-MIMO), the base station allocates a group identifier to a terminal group for performing and reporting signal measurements simultaneously. When the base station transmits control information including the group identifier, each one of terminals belonging to the terminal group performs signal measurement, generates signal measurement feedback, and simultaneously transmits the signal measurement feedback to the base station.

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。
