Abstract
Efficient transmission is performed in a case that an allocation periodicity is shorter than an interval based on repeated transmission. For configuration grant scheduling, in a case that the allocation periodicity is shorter than the interval based on the repeated transmission, a port number for a DMRS is determined according to the number of repetitions to allow a base station apparatus to determine which periodicity corresponds to the start of the transmission. Thus, by detecting the port number for the DMRS, the base station apparatus can recognize the start or the end of the transmission by the terminal apparatus.
Claims6
A terminal apparatus for communicating with a base station apparatus through configured grant scheduling, the terminal apparatus comprising:
- a higher layer processing unit configured to configure higher layer signaling using at least the number of repetitions and an allocation periodicity as parameters for the configured grant scheduling;
- and
- a transmitter configured to transmit a demodulation reference signal (DMRS), wherein
- the transmitter determines a port number for the DMRS based on a current number of repetitions.
A base station apparatus for communicating with a terminal apparatus through configured grant scheduling, the base station apparatus comprising:
- a higher layer processing unit configured to configure higher layer signaling using at least the number of repetitions and an allocation periodicity as parameters for the configured grant scheduling;
- and
- a receiver configured to receive a demodulation reference signal (DMRS), wherein
- the receiver performs reception processing assuming that a port number for the DMRS is determined based on a current number of repetitions.
