APPARATUS AND METHOD FOR MAPPING UPLINK DEMODULATION-REFERENCE SIGNAL SEQUENCE

摘要

The invention discloses a kind of method and apparatus,Mapping (DM-RS) sequence for uplink demodulation reference signal. This method includes: comprising steps of terminal generates uplink DM-RS sequences for mapping uplink demodulated reference signal; Terminal is distributed in the more than one resource block of mapping step uplink DM-RS sequences; Pass through uplink subframe with the terminal transmission uplink DM-RS sequences of step. Uplink DM-RS sequences are mapped to the sub-frame of uplink for being transmitted through the first card slot or the second slot; Uplink DM-RS sequences include the first uplink DM-RS sequences and the second uplink DM-RS signal sequences; It is generated with the first uplink DM-RS sequences and the second uplink DM-RS sequences and is based on identical reduction reference signal sequence. First uplink DM-RS sequences and the second uplink DM-RS sequences can be mapped to and cross one another, and distribute to a time slot along the SC-FDMA symbols in (multiple) box of frequency domain resource. ;The 2015 of copyright KIPO submissions
