TRANSMISSION DEVICE AND TRANSMISSION METHOD

摘要

Provided is a transmission device with which, by orthogonalizing different transmission bandwidth DM-RSs, CoMP performance is improved, and it is possible to increase MU-MIMO communication multiplexing. In the device, a sequence generator unit (103) generates a reference signal of a number of transmission bandwidths which is less than a prescribed number using a first sequence which is used in a reference signal of a number of transmission bandwidths which is greater than or equal to the prescribed number when a coordinated receiving by a plurality of receiving devices is applied, and generates the reference signal of the number of transmission bandwidth which is less than the prescribed number using a second sequence which differs from the first sequence when the coordinated receiving is not applied. A transmission unit (112) transmits the reference signal.

主权项

1. A transmitting apparatus comprising:
a generating section that generates, when coordinated reception at a plurality of receiving apparatuses is applied, a reference signal having a transmission bandwidth less than a predetermined number using a first sequence used for a reference signal having a transmission bandwidth equal to or greater than the predetermined number, and that generates, when the coordinated reception is not applied, the reference signal having a transmission bandwidth less than the predetermined number using a second sequence different from the first sequence; and a transmitting section that transmits the reference signal.
