Abstract
In the present invention, regarding a narrowband used in a subframe for transmitting uplink data, if a switch is made from a first narrowband used in a first subframe to a second narrowband that is different from the first narrowband, with respect to a second subframe continuing to the first subframe, a final one symbol of the first subframe and an initial one symbol of the second subframe are punctured and set as a retuning time to transmit the uplink data in the first narrowband and the second narrowband.
Claims14
A communication apparatus comprising:
- circuitry, which, in operation,
- sets a retuning time, when retuning from a first narrowband for transmitting a first channel in a first subframe to a second narrowband for transmitting a second channel in a second subframe, the second subframe being consecutive to the first subframe along a time axis;
- and
- a receiver, which, in operation, receives the first channel and the second channel, wherein:
- when the first channel and the second channel are a PUCCH (Physical Uplink Control Channel) for transmitting a channel state information (CSI), a last symbol of the first subframe and a first symbol of the second subframe are set as the retuning time, and at least one of the CSI is punctured for the retuning time.
