Patent ID: 8649333

Claim:
A radio transmitting apparatus in which a connection subframe connecting a plurality of subframes is used as one unit in transmission processing, the radio transmitting apparatus comprising: a selecting section that selects, per sub frame, a localized resource block scheme or a distributed resource block scheme as a resource allocation scheme; and an allocating section that allocates data in the connection subframe to frequency resources per subframe according to the selected resource allocation scheme; and a reporting section that reports, to a radio receiving apparatus, control information indicating a timing for switching the resource allocation scheme from the localized resource block scheme to the distributed resource block scheme, wherein the selecting section switches the resource allocation scheme from the localized resource block scheme to the distributed resource block scheme in the connection subframe, and determines a timing for switching the resource allocation scheme from the localized resource block scheme to the distributed resource block scheme based on a delay time from a timing of receiving a channel quality indicator from the radio receiving apparatus or based on a moving speed of the radio receiving apparatus.
