Abstract

A user equipment (UE) is described. The UE includes receiving circuitry configured to receive 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 are used for defining a time domain allocation for a physical uplink shared channel (PUSCH) transmission. The receiving circuitry is also configured to detect in a UE specific search space, a downlink control information (DCI) format comprising first information used for indicating a row index to the first allocation table or the second allocation table. The DCI format is used for scheduling of the PUSCH. The UE also includes transmitting circuitry configured to perform, based on a detection of the DCI format, the PUSCH transmission based on either of the first allocation table or the second allocation table.

First claim

What is claimed is:

1. A user equipment (UE) comprising:
receiving circuitry configured to receive 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 receiving circuitry configured to detect 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
transmitting circuitry configured to perform, 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 .

2. 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 .

3. 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 .

4. A communication method of a base station apparatus comprising:
transmitting 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,
transmitting 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 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
receiving 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 .
