Title: WIRELESS COMMUNICATION DEVICE, METHOD, PROGRAM, AND RECORDING MEDIUM
Abstract:
The present invention makes it possible to reduce interference that occurs in a resource element located at the end in the frequency direction or time direction among allocated wireless resources in a communication method for mapping symbols in resource elements arranged in the frequency direction and time direction. To this end, a first wireless communication device (300) is equipped with an orthogonal coding unit (171) for generating a second symbol set from a first symbol set to be transmitted to a second wireless communication device (400) by using a plurality of orthogonal codes, and a resource mapping unit (173) for mapping the second symbol set in interfering resources which interfere with a target resource element. The target resource element is positioned at the end in the frequency direction or time direction among the wireless resources allocated to the first wireless communication device (300) or the second wireless communication device (400). Each of the plurality of orthogonal codes includes N number of elements, the interfering resources equal N number of resource elements, and N is an odd number.
