Claim 5:
6. A user equipment (UE) comprising:
a receiver, 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 filed with an index value that is to be used for the plurality of PUSCH transmissions;
a processor, which in operation, determines time-domain resources based on the received uplink grant, the determined time-domain resources prescribing a number of PUSCH transmissions and a length of each of the number of PUSCH transmissions;
a transmitter, 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 processor, in operation, determines a DMRS port number to be used for each of the at least one front-loaded DMRS of the number of PUSCH transmissions based on the received index value,
and, in case at least two of the number of PUSCH transmissions have different lengths, and in case different numbers of symbols are permissible for each of the at least one front-loaded DMRS,
the transmitter, in operation, transmits the same or a smaller number of PUSCH transmissions such that, for none of the comprised at least one front-loaded DMRS, a different determined DMRS port number is used.
