Claim of US Patent No. 10,397,946

1. A method of transmitting an uplink reference signal by a terminal in a wireless communication system, the method comprising:receiving configuration information on an uplink reference signal for a physical uplink shared channel (PUSCH) from a base station; and
transmitting the uplink reference signal in at least one transmission time interval (TTI) from among a plurality of contiguous TTIs based on the configuration information,
wherein each of the plurality of contiguous TTIs consists of one or more single carrier frequency division multiple access (SC-FDMA) symbols in a time domain,
wherein the configuration information is included in signaling that schedules the PUSCH in a TTI from among the plurality of contiguous TTIs,
wherein the configuration information includes a first bit field for indicating one of a plurality of predefined candidate patterns for transmission of the uplink reference signal, and
wherein each of the plurality of predefined candidate patterns indicates at least one SC-FDMA symbol for transmission of the uplink reference signal from among SC-FDMA symbols included in the plurality of contiguous TTIs.
