Abstract
A terminal apparatus configured to transmit a time continuous signal for a first subcarrier in a first time symbol, and to generate the time continuous signal based on at least a first complex-valued symbol to which a phase rotation is applied. The phase rotation is given based on at least a subcarrier index of the first subcarrier.
Claims7
A terminal apparatus comprising:
- a transmitter configured to transmit a time continuous signal for a first subcarrier in a first time symbol;
- and
- a receiver configured to receive a Narrowband Physical Downlink Control Channel (NPDCCH) including downlink control information indicating a subcarrier index of the first subcarrier to which the time continuous signal corresponds, wherein
- the transmitter is further configured to generate the time continuous signal based on at least a first complex-valued symbol to which a phase rotation is applied;
- wherein
- the phase rotation is initialized for each transmission instance,
- the phase rotation is given based on at least the subcarrier index of the first subcarrier,
- the each transmission instance includes a plurality of time symbols, and
- the each transmission instance includes repeat transmissions of Narrow Band Physical Uplink Shared Channels (NPUSCHs).
