Title: SYSTEM AND METHOD FOR MAPPING UPLINK CONTROL INFORMATION
Abstract:
A user equipment (UE) may map a demodulation reference signal (DMRS) sequence to a first symbol in a set of resource blocks (RBs) of an uplink long burst, and the first symbol may occur at the beginning of the uplink long burst. The DMRS sequence may be "front-loaded" in the uplink long burst. The DMRS sequence may be dependent upon RB locations. When the DMRS sequence is mapped to the beginning of an uplink long burst, uplink control information (UCI) may be mapped in a physical uplink shared channel (PUSCH). A UE may map UCI in a PUSCH after the DMRS sequence is mapped to the beginning of the uplink long burst. When the base station receives an uplink long burst including the front-loaded DMRS and the UCI mapped in the PUSCH, the base station may identify the DMRS for channel estimation/interference cancelation of the UCI carried on the PUSCH.
