Abstract:
The present invention is designed to allow more DM-RS sequences to be allocated, and more DM-RS resources to be secured. The radio communication method of the present invention has a characteristic of generating DM-RS sequences using ZC sequences that are allocated in a new number of randomized sequences between the number of randomized sequences corresponding to a ZC sequence having a length of the largest prime number, not exceeding the ZC sequence length required in the uplink DM-RS, and the number of randomized sequences defined in Rel. 10 LTE.
