Abstract
A terminal includes a receiver that receives information related to a time window over a plurality of slots and a processor that controls transmission of a plurality of demodulation reference signals in the plurality of slots. Amplitudes and phases of the plurality of demodulation reference signals have continuity. The time window includes a first time resource that is not for uplink.
Claims3
A terminal comprising:
- a receiver that receives information related to a time window over a plurality of slots including a first slot that includes symbols for uplink and a second slot that does not include symbols for uplink;
- and
- a processor that controls transmission of a plurality of demodulation reference signals in the plurality of slots, wherein
- amplitudes and phases of the plurality of demodulation reference signals have continuity throughout the time window,
- allocation of the first slot and the second slot is dynamically indicated by a time division duplex pattern,
- the second slot allocated for any of the plurality of demodulation reference signals is changed as a resource for uplink, and
- the time window starts from the second slot, the second slot being located a preconfigured number of slots before a Physical Uplink Shared Channel (PUSCH) slot, the preconfigured number of slots being defined in a specification.
