Abstract: A method for generating an SRS sequence by a terminal may comprise the steps of: calculating a first root value for generation of an SRS sequence of a first block among concatenated blocks configured for transmission of an SRS, using a terminal-specific SRS identifier; calculating a second root value for generation of an SRS sequence of a second block on the basis of the calculated first root value and a root offset value; and generating an SRS sequence for transmission of an SRS on the concatenated blocks by applying the first root value to the first block and applying the second root value to the second block.

Abstract: The present invention relates to a wireless communication system. In detail, the present invention is a method for transmitting data to a base station (BS) by a user equipment (UE) includes: receiving information on a contention-based Physical Uplink Shared Channel (PUSCH) zone including a plurality of contention-based PUSCH resource blocks from the base station (BS); allocating at least one contention-based PUSCH resource block for transmission of the data based on the information on contention-based PUSCH zone; and transmitting the data to the base station (BS).

Abstract: A method for monitoring a downlink control channel in a wireless communication system and an apparatus for the method are disclosed. More specifically, a method for monitoring a downlink control channel of a user equipment (UE) in a wireless communication system comprises receiving, by the UE, configuration information of a first discontinuous reception (DRX) mode based on a first transmission time interval (TTI) and configuration information of a second DRX mode based on a second TTI from an evolved-NodeB (eNB); and monitoring, by the UE, a first downlink control channel in a first DRX listening interval within a first DRX cycle based on the configuration information of the first DRX mode and a second downlink control channel in a second DRX listening interval within a second DRX cycle based on the configuration information of the second DRX mode, wherein the second DRX cycle is set to be shorter than the first DRX cycle.
