Terminal and method for transmitting a transmission signal

摘要

Disclosed are a wireless communication base station device and a division number determination method that improve the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit.

主权项

1. A terminal apparatus comprising:
a receiver, which, in operation, receives, from a base station, allocation information indicating a plurality of frequency resources that are allocated to the terminal apparatus, the plurality of frequency resources being inconsecutive in a frequency domain, and each of the plurality of frequency resources being comprised of a number of consecutive resource block(s); and a transmitter, which, in operation, transmits, to the base station, an uplink signal using the plurality of frequency resources that are allocated based on the allocation information, wherein: the number of consecutive resource blocks included in each of the plurality of frequency resources is equal to or greater than a first minimum number of resource block(s) in case of a first bandwidth, and the number of consecutive resource blocks included in each of the plurality of frequency resources is equal to or greater than a second minimum number of resource block(s) in case of a second bandwidth, the second minimum number being greater than the first minimum number, and the second bandwidth being greater than the first bandwidth.
