Wireless communication apparatus, allocated resource notifying method and data allocating method
First Claim
1. A base station apparatus comprising:
- an information generating section that generates resource allocation information that indicates at least two clusters of resource blocks to be allocated to a terminal apparatus, each cluster including one or more consecutive resource block groups (RBGs), wherein the at least two clusters are located on frequency positions separated from each other, and wherein the resource allocation information includes a combinatorial index that is calculated by using;
a starting RBG index (s1) of a first cluster;
an index (e1) obtained by adding one to an ending RBG index of the first cluster;
a starting RBG index (s2) of a second cluster;
an index (e2) obtained by adding one to an ending RBG index of the second cluster; and
a number N that is obtained by adding one to a total number of RBGs included in an uplink system bandwidth; and
a transmission section that transmits the resource allocation information.

Abstract
Provided are a radio transmission apparatus and a radio transmission method whereby the increase of number of signaling bits can be suppressed and further the flexibility of frequency scheduling can be improved. A notified RBG calculating unit (203) that adds a predetermined offset value of “1” or “−1” to one of the start RBG number and the end RBG number of allocated RBG number information (b′i) output by a scheduling unit (201), thereby calculating notified RBG number information (bi). An RBG total number setting unit (204) calculates the total number of RBGs, which is to be notified, by adding “1” to the total number of allocated RBGs. A notified information generating unit (205) applies the notified RBG number information (bi) and the notified total number of RBGs (Nrb′) to a predetermined formula, thereby generating and transmitting, to terminals, notified information (r).
