Patent ID: 11575477

Abstract:
User equipment for communicating with a base station includes a processing unit, wherein when transmitting a physical uplink shared channel (PUSCH) to the base station prior to establishment of a radio resource control (RRC) connection between the base station and the user equipment, the processing unit controls frequency hopping applied to the PUSCH and a demodulation reference signal; a reception unit for receiving from the base station information indicating that frequency hopping is applied to the PUSCH; and a transmission unit for transmitting the PUSCH and the demodulation reference signal to which frequency hopping is applied; wherein the demodulation reference signal for demodulating a single PUSCH is formed of one front-loaded demodulation reference signal and one additional demodulation reference signal, and when the duration in symbols of the PUSCH does not support one additional demodulation reference signal, the demodulation reference signal is formed of a front-loaded demodulation reference signal.
