Abstract: Slot-level remapping physical uplink control channels into two resource blocks, respectively located at two slots of a subframe, are generally adapted to a 3GPP LTE physical uplink. ACK/NAK resource blocks may be applied by the extended cyclic prefix, adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the normal cyclic prefix, and adapted to a complex 3GPP LTE physical uplink where mixed resource blocks (where the ACK/NAK and CQI channels coexist) may be applied by the extended cyclic prefix.

Abstract: Apparatuses (including base stations and terminals), systems, and methods for supporting both wideband and narrowband communications are described. In one aspect, a base station supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth is described, having an information formatter, a transceiver, and a controller. The information formatter generates a Low-end Master Information Block (L-MIB) and a Low-end System Information Block (L-SIB), which are transmitted by the transceiver to first type and second type terminals. The L-MIB includes control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe, while the L-SIB includes information on downlink reception and uplink transmission of the second type terminal. When the base station receives a Random Access Channel (RACH) preamble request from one of the terminals, the base station performs the random access procedure.

Abstract: The present invention relates to a procedure for transceiving a sounding reference signal and to a method for operating sounding in a wireless communication system in which an uplink control channel resource dynamically changes. More particularly, the method for transmitting a sounding reference signal by a terminal in a wireless communication system according to the present invention comprises the steps of: receiving uplink/downlink configuration information transmitted from a base station; checking whether a conflict occurs between a physical uplink control channel (PUCCH) resource region based on the uplink/downlink configuration information and a sounding reference signal (SRS); and skipping the transmission of the SRS upon the occurrence of a conflict. The present invention has the advantage of efficiently solving the problem of conflicts between the SRS and the uplink control channel resource without increasing the power consumption burden in the terminal or without excessive restrictions on an SRS transmission subframe or sounding band.
