1. An integrated circuit for controlling a user equipment (UE), the integrated circuit comprising:
receiving circuitry, which, in operation, receives a single uplink grant for a plurality of physical uplink shared channel (PUSCH) transmissions, the single uplink grant comprising an antenna port field with an index value to be used for the plurality of PUSCH transmissions;
processing circuitry, which, in operation, determines time-domain resources based on the received single uplink grant, the determined time-domain resources prescribing a number of PUSCH transmissions and a length of each of the number of PUSCH transmissions; and
transmitting circuitry, which, in operation, transmits the number of PUSCH transmissions using the determined time-domain resources, each of the number of PUSCH transmissions comprising at least one front-loaded demodulation reference signal (DMRS),
wherein
the processing circuitry, in operation, determines a higher number or a lower number of symbols to be used for each of the at least one front-loaded DMRS based on the received index value, and
in case at least two of the number of PUSCH transmissions have different lengths, and in case one of the at least two PUSCH transmissions cannot comprise the higher number of symbols for the at least one front-loaded DMRS, the transmitting circuitry transmits the number of PUSCH transmissions such that, for all of the at least one front-loaded DMRS, the lower number of symbols is used.
