    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）符号传输控制信道。 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。

    Abstract: An electronic device includes a first housing, a second housing connected to at least a portion of the first housing and movable with respect to the first housing, at least one display coupled with at least one of the first housing or the second housing, at least one microphone, at least one sensor and at least one processor. The at least one processor is configured to: obtain first audio data using the at least one microphone; identify that a form of the electronic device is changed according to relative movement of the first housing and the second housing, using the at least one sensor while the first audio data is obtained, identify noise data based on identifying that the form of the electronic device is changed, and obtain second audio data from the first audio data based on the identified noise data. The second audio data may include data in which at least a portion of noise, which is generated based on a change of the form of the electronic device and included in the first audio data, is reduced.
