Title:
TRANSMITTER APPARATUS, RECEIVER APPARATUS, SIGNAL GENERATING METHOD AND QUALITY ESTIMATING METHOD
Document Type and Number:
WIPO Patent Application WO/2012/140847
Kind Code:
A1
Abstract:
Provided is a transmitter apparatus that allows a base station to set, for each of a plurality of clusters, OCC sequences, which are to be used at terminals, without increasing the number of signaling bits. A DM-RS information determining unit (205) determines, according to a sequence determination rule, a cyclic shift sequence and an orthogonal sequence that are to be used for DM-RS to be allocated in each of the plurality of clusters. A DM-RS generating unit (206) generates the DM-RS by use of the cyclic shift sequence and orthogonal sequence determined by the DM-RS information determining unit (205). The sequence determination rule includes a plurality of sequence pattern candidates each comprising a first orthogonal sequence to be used at the antenna ports in a cluster (#1) and a second orthogonal sequence to be used at the antenna ports in a cluster (#2). In some of the plurality of pattern candidates, the first and second orthogonal sequences for the same antenna port are different from each other, while in the others of the plurality of pattern candidates, the first and second orthogonal sequences for the same antenna port are the same.
