Method, terminal and base station in a wireless communication system

A user equipment (UE) in a wireless communication system, the UE comprising:

• a transceiver;
• and
• at least one processor coupled to the transceiver and configured to:
• receive, from a base station, first configuration information,
• map a physical uplink channel in a first format, and
• transmit, to the base station, the physical uplink channel based on the first configuration information,
• wherein, to map the physical uplink channel in the first format, the at least one processor is further configured to:
• generate a first sequence based on second configuration information included in the first configuration information,
• generate at least one additional sequence based on the first sequence, and
• map the first sequence and the at least one additional sequence on at least one time-domain symbol for transmitting the physical uplink channel, and
• wherein the second configuration information is related to frequency-domain resources for transmitting the physical uplink channel.

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), first configuration information;
• and
• receiving, from the UE, a physical uplink channel based on the first configuration information,
• wherein the physical uplink channel is mapped in a first format,
• wherein the first configuration information includes second configuration information for frequency-domain resources for transmitting the physical uplink channel,
• wherein the second configuration information is used to generate a first sequence and at least one additional sequence based on the first sequence, and
• wherein the first sequence and the at least one additional sequence are mapped to at least one time-domain symbol for transmitting the physical uplink channel.
