User equipments, base stations and methods for time-domain resource allocation

A base station apparatus comprising:

• transmitting circuitry configured to transmit a radio resource control (RRC) message comprising a first parameter(s) used for configuring a first allocation table and a second allocation table, each of the first allocation table and the second allocation table being used for defining a time domain allocation for a physical uplink shared channel (PUSCH) transmission, wherein the first allocation table includes no more than 16 rows and the second allocation table includes up to 64 rows,
• the transmitting circuitry configured to transmit in a UE specific search space, a first downlink control information (DCI) format comprising first information used for indicating a row index to the first allocation table and a second DCI format comprising second information used for indicating a row index to the second allocation table, the first DCI format or the second DCI format being used for scheduling of the PUSCH, wherein the first information includes 4 bits and the second information includes up to 6 bits, and
• receiving circuitry configured to receive the PUSCH transmission based on either of the first allocation table or the second allocation table, wherein
• in a first case where the first DCI format is detected, the first allocation table used for the PUSCH transmission is determined,
• in a second case where the second DCI format is detected, the second allocation table used for the PUSCH transmission is determined, and
• the first DCI format is DCI format 0_0, and the second DCI format is not the DCI format 0_0.

A communication method of a user equipment (UE) comprising:

• receiving a radio resource control (RRC) message comprising a first parameter(s) used for configuring a first allocation table and a second allocation table, each of the first allocation table and the second allocation table being used for defining a time domain allocation for a physical uplink shared channel (PUSCH) transmission, wherein the first allocation table includes no more than 16 rows and the second allocation table includes up to 64 rows,
• detecting in a UE specific search space, a first downlink control information (DCI) comprising first information used for indicating a row index to the first allocation table format or a second DCI format comprising second information used for indicating a row index to the second allocation table, the first DCI format or the second DCI format being used for scheduling of the PUSCH, wherein the first information includes 4 bits and the second information includes up to 6 bits, and
• performing, based on a detection of the first DCI format or the second DCI format, the PUSCH transmission based on either of the first allocation table or the second allocation table, wherein
• in a first case where the first DCI format is detected, the first allocation table used for the PUSCH transmission is determined,
• in a second case where the second DCI format is detected, the second allocation table used for the PUSCH transmission is determined, and
• the first DCI format is DCI format 0_0, and the second DCI format is not the DCI format 0_0.
