Wireless communication apparatus and wireless communication method
First Claim
1. A radio communication apparatus comprising:
- a repetition section that repeats a data symbol and generates a plurality of same data symbols;
an error predicting section that predicts channel estimation errors in allocated locations of the generated same data symbols; and
a data symbol mapping section that maps the same data symbols in the allocated locations where amount of the predicted channel estimation error is a predefined threshold or less.

Abstract
A wireless communication method of repetition system and the like for ensuring that when the same data symbols are combined, a diversity gain is achieved. In a step (ST 420), a data symbol placing part (105) decides destination places of respective replicated data symbols (S1-S4) such that the same data symbols are not placed at destination place numbers (7,8) of data symbols that exhibit poor channel estimation precisions. In a step (ST 430), the data symbol placing part (105) places, in accordance with the decision in the foregoing step (ST 420), the four data symbols (S1-S4), which are received from a repetition part (102), in one frame received from a channel estimation error predicting part (104).
