    Abstract: A fractional Resource Block (RB) allocation method which enables resource allocation in a unit smaller than RB to improve the capacity of Voice over Internet Protocol (VoIP) in a Long Term Evolution (LTE) system is provided. The method includes generating modulation symbols streams by performing channel coding and modulation on transport blocks corresponding to first and second data to be transmitted to respective users, multiplexing the modulation symbols stream alternately in unit of two continuous modulation symbols, and transmitting the multiplexed modulation symbol stream as mapped to corresponding resource. A resource arrangement method allows different users to share the same resource without using a Space Domain Multiple Access (SDMA) and indicates fractional RB allocation.

    Abstract: A plasma etching apparatus may include a first source electrode, a first bias electrode, and a second bias electrode configured to generate a plasma by supplying energy to a process gas injected into a chamber; and a controller. The controller may be configured to supply a first high-frequency RF power, a first low-frequency RF power, and a second low-frequency RF power to the chamber during a first period from a first time to a second time; ramp down and turn off the first high-frequency RF power to the chamber during a second period from the second time to a third time; and ramp down and turn off the first low-frequency RF power to the chamber during a third period from the second time to a fourth time different from the third time. The third period may be smaller than ½ of the first period and greater than the second period.

    Abstract: In a wireless communication system, a control channel is required in order to use limited resources effectively. However, the control channel resource is part of the system overhead, and thus reduces the data channel resource used for data transmission. In the long term evolution (LTE) system based on OFDM, one sub frame the consists of fourteen OFDM symbols wherein a maximum of three OFDM symbols are used for the control channel resource and remaining eleven OFDM symbols are used for the data channel resource. Therefore, the quantity of energy that can be transmitted for the control channel resource is extremely limited compared to the data channel resource. For this reason, the coverage of the control channel becomes less than that of the data channel, and even if a user can successfully receive the data channel, reception failure of a control channel sometimes results in failure of data recovery. In the present invention, in order to expand the coverage of the control channel to at least the coverage of the data channel, the time resource of the transmission resource wherein the control channel is transmitted is expanded and allocated for sending and receiving the control channel. By way of methods for extending the time resource are provided a method wherein a plurality of sub frames are used to transmit one control channel, and a method wherein a part of a data channel is used for the control channel.

    Abstract: Methods and apparatuses are provided for reporting power headroom of a user equipment (UE). It is determined whether a simultaneous physical uplink control channel (PUCCH) and physical uplink shared channel (PUSCH) transmission is configured. First power headroom information and second power headroom information are, if the simultaneous PUCCH and PUSCH transmission is configured. The first power headroom information and the second power headroom information are simultaneously transmitted to a base station. The first power headroom information is obtained by subtracting a PUSCH transmit power from a maximum UE transmit power in a subframe, and the second power headroom information is obtained by subtracting a PUCCH transmit power and the PUSCH transmit power from the maximum UE transmit power in the subframe.
