摘要:
A femto cell connection node, a femto cell system, and a data transmission method of the system are disclosed.In the case where a sending terminal is willing to transmit data to a receiving terminal, a femto cell connection node of the sending side determines a present connection state of the receiving terminal and determines a transmission format of the data to be transmitted from the sending terminal to the receiving terminal according to the determined connection state. In particular, in the present disclosure, in the case where the receiving terminal is in a state of being directly or indirectly connectable to an Internet Protocol (IP) network, the data is transmitted to the receiving terminal after changing a protocol portion L1/L2 so that the data may pass through the IP network.

Provided is a method and apparatus for transmitting a reference signal by a base station in a multi-cell cooperative communication environment. The method for transmitting the reference signal according to the present invention comprises the steps of: transmitting cell ID information of a second cell to a terminal which uses a first cell as a serving cell; generating reference signal sequences in the first cell and the second cell on the basis of the same cell ID; and performing resource element mapping on each of the generated reference signals, generating signals, and transmitting the signals to the terminal, wherein the same cell ID used in generating the reference signal sequences is a cell ID of the first cell or a cell ID of the second cell.

A method and device for sending and receiving control information and data between a terminal and an eNB in a wireless communication system are disclosed, and a method and device for sending and receiving control information and data in accordance with hybrid automatic repeat technology are disclosed. A multiplexer outputs a plurality of hybrid repeat (HARQ) blocks that store data blocks to be transmitted via a plurality of component carrier waves, and outputs multiplexed data obtained by the multiplexing of the data blocks. Repeat data is transmitted by using a component carrier wave that differs from the component carrier wave used during the initial transmission, thereby obtaining gain of diverse channel states for predetermined component carrier waves and frequency bands, and so improving HARQ performance.
摘要:
A method of inducing explosive atomization of materials is provided using a metal-oxide-semiconductor (MOS)-based structure under electrical excitation. Explosive atomization of the gate electrode and surrounding dielectric materials creates a microplasma that is substantially confined with the device at the metal/dielectric interface. The device can generate a microplasma in either the accumulation or inversion regime. The high degree of confinement of the microplasma allows chip-scale implementation of atomic emission spectroscopy and detection using a minimal amount of analyte.
