摘要： A method of transmitting a sounding reference signal (SRS) in a wireless communication system is discussed. The method according to one embodiment includes receiving a first UE-specific configuration indicating possible subframes for aperiodic SRS transmission via a radio resource control (RRC) signaling, wherein the possible subframes are periodically configured; receiving a physical downlink control channel (PDCCH) signal including request information of requesting aperiodic SRS transmission; and transmitting at least one SRS one time in response to the request information within the possible subframes.

摘要： A method of transmitting pilot signals in a system which performs communication using two or more earners comprises transmitting first pilots and second pilots from at least one user equipment to a base station, the first and second pilots, which are transmitted from the at least one user equipment, being multiplexed by code division multiplexing, and the first and second pilots, which are transmitted from a specific user equipment, having different transmission powers, and transmitting data from the at least one user equipment to the base station depending on the first pilots and the second pilots. Since many UEs can transmit CQ pilots, exact channel estimation can be performed and thus communication efficiency can be improved.

摘要： A method and apparatus for allowing a UE to transmit uplink signals using a MIMO scheme are disclosed. In order to maintain good Peak power to Average Power Ratio (PAPR) or Cubic Metric (CM) properties when the UE transmits uplink signals using the MIMO scheme, the UE uses a precoding scheme based on a precoding matrix established in a manner that one layer is transmitted to each antenna in specific rank transmission.

摘要： A method of acquiring information on a resource region for transmitting PHICH and a method of receiving PDCCH using the same are disclosed. The resource region for transmitting the PHICH can be specified by first information corresponding to the per-sub frame PHICH number and second information corresponding to a duration of the PHICH within the subframe. The first Information can be specified into a form resulting from multiplying a predetermined basic number by a specific constant. And, the specific constant can be transmitted via PBCH. Moreover, the second information can be acquired from the PBCH as well.

摘要： The present invention provides for applying a cyclic redundancy check (CRC) to a data signal. The present invention includes attaching a first CRC to a first data signal block having a first length, segmenting the first data signal block attached with the first CRC into a plurality of second data signal blocks having a length shorter than the first length, respectively generating a second CRC for each second data signal block, and attaching the generated second CRC to the respective second data signal block. Moreover, the first CRC and second CRC may be generated from respectively different CRC generating polynomial equations.

摘要： A method for receiving, by a first device, data from a second device. The first device receives modulation and coding related information and resource related information for a transport block with a size for the data, and receives second cyclic redundancy check (CRC) attached code blocks to which a first CRC attached transport block corresponding to the transport block is mapped. The first device obtains the transport block with the size from the second CRC attached code blocks based on the modulation and coding related information and resource related information. The modulation and coding related information and the resource related information represent the size of the transport block. The size of the transport block is one of a plurality of predetermined transport block sizes. The plurality of predetermined transport block sizes are predetermined such that all the second CRC attached code blocks have a same size as each other.
