Title:
UPLINK DEMODULATION REFERENCE SIGNALS IN ADVANCED WIRELESS COMMUNICATION SYSTEMS
Document Type and Number:
WIPO Patent Application WO/2014/157921
Kind Code:
A1
Abstract:
User equipment is provided to communicate with a base station. The user equipment includes a transceiver. The transceiver configured to transmit a physical uplink shared channel (PUSCH). A DMRS is mapped on a single, single carrier frequency division multiplexing (SC-FDM) symbol of a subframe. Data and acknowledgement (HARQ-ACK) information is mapped on remaining SC-FDM symbols of the subframe. The HARQ-ACK information is mapped on virtual subcarriers on two SC-FDM symbols next to the single SC-FDM symbol with the DMRS.
