Abstract
A terminal is disclosed communicating using a first carrier performing at least Downlink (DL) transmission and a second carrier performing only Uplink (UL) transmission. The terminal includes a receiver that receives an indication regarding a UL, the indication included in downlink control information (DCI) that is reported from the first carrier and a processor that transmits a UL signal using the UL based on the indication. In other aspects, a radio communication method, a base station, and a system are also disclosed.
Claims11
A terminal communicating using a first carrier performing at least Downlink (DL) transmission and a second carrier, which is a supplemental Uplink (UL), performing only UL transmission, the terminal comprising:
- a receiver that receives an indication regarding a UL that is reported from the first carrier;
- and
- a processor that transmits a UL signal using the UL based on the indication,
- wherein the processor controls to not transmit a Physical Uplink Control Channel (PUCCH) on the second carrier.
A radio communication method for a terminal communicating using a first carrier performing at least Downlink (DL) transmission and a second carrier, which is a supplemental Uplink (UL), performing only UL transmission, the method comprising:
- receiving an indication regarding a UL that is reported from the first carrier;
- transmitting a UL signal using the UL based on the indication;
- and
- controlling to not transmit, by the terminal, a Physical Uplink Control Channel (PUCCH) on the second carrier.
A base station communicating using at least one of:
- a first carrier performing at least Downlink (DL) transmission, and
- a second carrier, which is a supplemental Uplink (UL), performing only UL transmission,
- the base station comprising:
- a transmitter that transmits, in the first carrier, an indication regarding a UL;
- and
- a processor that receives a UL signal using the UL based on the indication,
- wherein the processor controls to not receive a Physical Uplink Control Channel (PUCCH) on the second carrier.
A system comprising a terminal, communicating using a first carrier performing at least Downlink (DL) transmission and a second carrier, which is a supplemental Uplink (UL), performing only UL transmission, and a base station, wherein:
- the base station comprises:
- a transmitter that transmits, in the first carrier, an indication regarding a UL;
- and
- a first processor that receives a UL signal using the UL based on the indication, and
- the terminal comprises:
- a receiver that receives the indication;
- and
- a second processor that transmits the UL signal using the UL based on the indication,
- wherein the second processor controls to not transmit a Physical Uplink Control Channel (PUCCH) on the second carrier.
