Abstract:
1. A method for allocating communication resource for control signal transmission within a transmission unit resource region for a random access channel (RACH) signal transmission, the method comprising: configuring a user equipment with a RACH resource region for the RACH signal transmission, wherein the RACH resource region is specified by a time domain region and a frequency domain region; allocating a first sequence set used only for a random access and a second sequence set used only for a control signal to the user equipment, wherein the first sequence set includes at least one sequence for indicating the random access and the second sequence set includes at least one sequence for indicating the control signal, and the first sequence set is discriminated from the second sequence set by code division multiplexing; and receiving a sequence selected by the user equipment from the user equipment, wherein the selected sequence belongs to either the first sequence set or the second sequence set, wherein, if the selected sequence belongs to the first sequence set, the RACH signal is transmitted by the user equipment by transmitting, within the time domain region and the frequency domain region configured as the RACH resource region, a sequence selected from the first sequence set, wherein, if the selected sequence belongs to the second sequence set, the control signal is transmitted by the user equipment by transmitting, within the same time domain region and the same frequency domain region as the RACH resource region, a sequence selected from the second sequence set, and wherein the control signal includes channel quality information.
