    摘要: The present invention relates to a wireless communication system, and more particularly to a method and apparatus for efficient contention-based transmission in a wireless communication system. The method for performing contention-based transmission in a wireless communication system according to one embodiment of the present invention comprises: setting a radio resource control (RRC) connection with a receiver end where the contention-based transmission is received; setting a resource area for the contention-based transmission to allow a collision with other transmission; and transmitting at least one of the data and control information on the resource area, wherein the resource area for the contention-based transmission can be hopped on a physical resource.

    摘要: A method for generating/transmitting a transmission-unit symbol sequence is disclosed. In the case of transmission information, the information is modulated in time and frequency domains on the basis of a predetermined transmission unit (e.g., a transmission time interval TTI or slot), simultaneous transmission of the information is made, and then a transmission unit symbol is generated/transmitted. A transmission sequence is masked in each symbol contained in one transmission unit. Symbol-unit circular shift (cyclic shift) is applied to the masked result, so that transmission efficiency increases. A control signal transmission method for supporting a variety of formats and a signal transmission method based on a prime-length sequence are also provided.

    摘要: Disclosed are a method and apparatus for transmitting a reference signal. In a base station apparatus for transmitting a reference signal in a wireless communication system, a processor generates the same scrambling sequence for resource elements (REs) allocated to each layer for reference signal transmission, and spreads or covers Walsh codes such that scrambling sequences generated for the resource elements can be orthogonal to each other on a time axis, in order to generate a reference signal sequence. Here, the Walsh code spreading or covering by the processor is applied on a frequency axis on the basis of a plurality of resource blocks (RBs) or on the basis of a pair of resource blocks, such that mutually different sequences having mutually different sequence values can be mapped between resource blocks or between pairs of resource blocks. A transmission module transmits the reference signal, to which the thus-generated reference signal sequence is applied, to user equipment via each layer.
