Abstract:
In a cell having a system bandwidth wide enough to allow a RACH from a UE and a PUSCH from another UE to be frequency-division multiplexed in the same subframe, a PUCCH unattached to the PDSCH and the RACH are frequency-division multiplexed in the same subframe. In a cell having a narrow system bandwidth, a PUCCH unattached to the PUSCH and the RACH are time-division multiplexed, and the RACH is transmitted for a period for a BCH or others not required to feed ACK/NACK back to a base station apparatus. Alternatively, the PUCCH unattached to the PUSCH and the RACH are frequency-division multiplexed, and the bandwidth for the RACH may be set to be narrower than the bandwidth scheduled for the RACH in a cell having a wider system bandwidth.
