Abstract

A user equipment (UE) is described. The UE includes receiving circuitry configured to receive a first DCI format comprising one bit of an uplink shared channel (UL-SCH) indicator, the first DCI format being used for scheduling of a PUSCH. The receiving circuitry is also configured to receive a second DCI format comprising more than one bits of an UL-SCH indicator, the second DCI format being used for scheduling of a PUSCH. The UE also includes transmitting circuitry configured to perform, based on a detection of the first DCI format, a transmission on the PUSCH. The transmitting circuitry is also configured to perform, based on a detection of the second DCI format, a transmission on the PUSCH. The one bit of the UL-SCH indicator is used for indicating whether or not UL-SCH is transmitted on the PUSCH. The more than one bits of the UL-SCH indicator are used for indicating whether or not UCI is transmitted on the PUSCH.

Claims (18)

1. A user equipment (UE) comprising:

receiving circuitry configured to receive a first downlink control information (DCI) format comprising one bit of a first uplink shared channel (UL-SCH) indicator, the first DCI format being used for scheduling of a first physical uplink shared channel (PUSCH); and

transmitting circuitry configured to perform, based on a detection of the first DCI format, a transmission on the first PUSCH, wherein

the receiving circuitry is further configured to receive a second DCI format comprising zero bit or one bit of a second UL-SCH indicator, the second DCI format being used for scheduling of a second PUSCH,

the transmitting circuitry is further configured to perform, based on a detection of the second DCI format, a transmission on the second PUSCH,

in a case that a number of bits of the second UL-SCH indicator is zero, the transmitting circuitry is further configured to determine that the number of bits of the second UL-SCH indicator is zero,

in a case that the number of bits of the second UL-SCH indicator is one, the transmitting circuitry is further configured to determine that the number of bits of the second UL-SCH indicator is one,

the first UL-SCH indicator indicates whether or not a UL-SCH is transmitted on the first PUSCH, and

in a case that the number of bits of the second UL-SCH indicator is one, the second UL-SCH indicator indicates whether or not a UL-SCH is transmitted on the second PUSCH.

2. A method performed by a user equipment (UE), the method comprising:

receiving a first downlink control information (DCI) format comprising one bit of a first uplink shared channel (UL-SCH) indicator, the first DCI format being used for scheduling of a first physical uplink shared channel (PUSCH);

performing, based on a detection of the first DCI format, a transmission on the first PUSCH;

receiving a second DCI format comprising zero bit or one bit of a second UL-SCH indicator, the second DCI format being used for scheduling of a second PUSCH;

performing, based on a detection of the second DCI format, a transmission on the second PUSCH;

in a case that a number of bits of the second UL-SCH indicator is zero, determining that the number of bits of the second UL-SCH indicator is zero;

in a case that the number of bits of the second UL-SCH indicator is one, determining that the number of bits of the second UL-SCH indicator is one bit, wherein

the first UL-SCH indicator indicates whether or not a UL-SCH is transmitted on the first PUSCH, and

in a case that the number of bits of the second UL-SCH indicator is one, the second UL-SCH indicator indicates whether or not a UL-SCH is transmitted on the second PUSCH.
