無線端末装置及び無線基地局装置
Document Type and Number:
Japanese Patent JP4689646
Kind Code:
B2
Abstract:
To arrange control information appropriately in a wireless resource in the downlink of a wireless system such as an E-UTRA system.
In the downlink from a wireless base station apparatus to a wireless terminal apparatus, a PCFICH is arranged from a top subcarrier of a first OFDM symbol in a subframe, ACK/NACK(ACK/NACK for UL) signals for an uplink from the wireless terminal apparatus to the wireless base station apparatus are blocked in a frequency region and multiplexed, and then an ACK/NACK signal and the PDCCH are multiplxed using frequency division multiplexing or time division multiplexing.
