A base station transmits a random access response in response to a random access request (random access preamble) of a user equipment. The random access response includes information about a time when the random access request is transmitted and sequence number information of the random access request (random access preamble). The user equipment checks whether the received random access response is the response of the random access request transmitted by the user equipment, using the information about the time when the random access request is transmitted and the sequence number information included in the received random access response.

Method for transmitting and receiving random access request and transmitting and receiving random access response

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for allocating an uplink carrier for transmitting uplink control information in a wireless communication system that supports carrier aggregation. According to one embodiment of the present invention, a method for transmitting uplink control information in a wireless communication system that supports carrier aggregation of M (M&#x2265;1) uplink component carriers comprises: a step of receiving setup information on a primary uplink component carrier, from among said M uplink component carriers, via which one or more pieces of uplink control information are to be transmitted; a step of multiplexing said one or more pieces of uplink control information; and a step of transmitting the multiplexed uplink control information through the primary uplink component carrier.

A symbol mapping method for repetition coding is disclosed. The symbol mapping method comprises performing repetition coding on codeword to output repeated codeword symbols, and mapping the repeated codeword symbols with subcarriers located in different localized resource blocks. According to the embodiments of the present invention, it is possible to obtain maximum reliability in a receiving side by mapping codeword bits with subcarriers to reduce the number of bits having low reliability when a transmitting side uses repetition coding. Also, it is possible to improve decoding throughput and obtain channel diversity.
