摘要:
Disclosed is a method for transmitting a sounding reference signal (SRS) in a cooperative communication system. The method comprises receiving, from a macro base station, SRS resource information indicating transmission resources of an SRS to be transmitted by a user equipment (UE); transmitting the SRS and uplink data based on a UE-specific SRS subframe configuration included in the SRS resource information when the SRS resource information includes the UE-specific SRS subframe configuration information; and transmitting the SRS and the uplink data based on a pre-stored cell-specific SRS subframe configuration when the SRS resource information does not include the UE-specific SRS subframe configuration information. When a destination of the SRS to be transmitted by the UE is selected as a base station related to the macro base station, the SRS resource information includes the UE-specific SRS subframe configuration information of the base station selected as the destination of the SRS.

A method of fabricating a semiconductor device includes forming a plurality of mask patterns comprising a real mask pattern and a dummy mask pattern on a substrate, removing the dummy mask pattern and etching the substrate using the real mask pattern as a mask to form a first trench, a second trench, and a fin-type pattern defined by the first trench and the second trench. The second trench contacting the fin-type pattern comprises a smooth pattern which is convex and positioned between a bottom surface and a side surface of the second trench, a first concave portion which is positioned between the side surface of the second trench and the smooth pattern, and a second concave portion which is positioned between the convex portion and the bottom surface of the second trench.

An apparatus and a method for transmitting/receiving downlink data channel signal transmission information in a cellular radio communication system using a Cooperative Multi-Point (CoMP) scheme are provided. In the downlink data channel signal transmission information transmission method, a Base Station (BS) transmits downlink data channel signal transmission information including information related to Resource Elements (REs) scheduled for a downlink data channel signal transmission to a User Equipment (UE), and transmits downlink data channel signal non-transmission information including information related to REs through which a downlink data channel signal is not transmitted among the REs scheduled for the downlink data channel signal transmission to the UE.

A semiconductor device includes a substrate including a first trench, a first fin pattern on the substrate that is defined by the first trench, a gate electrode on the substrate, and a field insulating layer on the substrate. The first fin pattern includes an upper part on a lower part. The first fin pattern includes a first sidewall and a second sidewall opposite each other. The first sidewall is concave along the lower part of the first fin pattern. The second sidewall is tilted along the lower part of the first fin pattern. The field insulating layer surrounds the lower part of the first fin pattern. The gate electrode surrounds the upper part of the first fin pattern.
摘要:
The present invention relates to a method for transmitting an uplink channel in a wireless communication system. The method for transmitting an uplink channel of a terminal according to one embodiment of the present invention may comprise the steps of: receiving a downlink control message; extracting the starting point of a dynamic physical uplink control channel (PUCCH) resource region from the downlink control message; and transmitting an uplink channel according to the starting point of the extracted dynamic PUCCH resource region. An embodiment of the invention exhibits effects in reducing the signaling overhead, and preventing the terminal from unnecessarily consuming power, when transmitting the uplink channel in a CoMP system.
