Method of transmitting a scheduling request on an uplink control channel in a wireless communication system and user equipment comprising a processor for transmitting the scheduling request

摘要

A method of transmitting a scheduling request which is used to request a radio resource for uplink transmission includes determining a subframe for transmitting the scheduling request, the subframe comprising two consecutive slots, each slot comprising a plurality of single carrier-frequency division multiple access (SC-FDMA) symbols, the scheduling request being carried by presence or absence of transmission of uplink control channel configuring an uplink control channel for transmission of the scheduling request in that subframe, and transmitting the scheduling request on the uplink control channel.
The SC-FDMA symbols in each slot are divided into a first and a second set of SC-FDMA symbols and the frequency domain sequences are mapped to each of the SC-FDMA sets. Each of the frequency domain sequences is cycle shifted with respect to each other, and each set of mapped frequency domain sequences is spread with a corresponding first or second orthogonal sequence having a length equal to the number of SC-FDMA symbols in the respective first or second set.
