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, the receiving circuitry 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 being used for scheduling of the PUSCH, 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, wherein whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a radio network temporary identifier (RNTI) used for scrambling of cyclic redundancy check (CRC) for the DCI format.

2 . The UE according to the claim 1 , wherein
whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a value of second information comprised in the DCI format.

3 . The UE according to the claim 2 , wherein
the receiving circuitry is configured to receive a RRC message comprising a second parameter(s) used for configuring whether or not the second information is present in the DCI format.

4 . 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, the transmitting circuitry configured to transmit 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 being used for scheduling of the PUSCH, receiving circuitry configured to receive the PUSCH transmission based on either of the first allocation table or the second allocation table, wherein whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a radio network temporary identifier (RNTI) used for scrambling of cyclic redundancy check (CRC) for the DCI format.

5 . The base station apparatus according to the claim 4 , wherein
whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a value of second information comprised in the DCI format.

6 . The base station apparatus according to the claim 5 , wherein
the transmitting circuitry is configured to transmit a RRC message comprising a second parameter(s) used for configuring whether or not the second information is present in the DCI format.

7 . 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, detecting 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 being used for scheduling of the PUSCH, performing, based on a detection of the DCI format, the PUSCH transmission based on either of the first allocation table or the second allocation table, wherein whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a radio network temporary identifier (RNTI) used for scrambling of cyclic redundancy check (CRC) for the DCI format.

8 . The communication method according to claim 7 , wherein
whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a value of second information comprised in the DCI format.

9 . The communication method according to claim 8 , wherein
receiving a RRC message comprising a second parameter(s) used for configuring whether or not the second information is present in the DCI format.

10 . 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, transmitting 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 being used for scheduling of the PUSCH, receiving the PUSCH transmission based on either of the first allocation table or the second allocation table, wherein whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a radio network temporary identifier (RNTI) used for scrambling of cyclic redundancy check (CRC) for the DCI format.

11 . The communication method according to claim 10 , wherein
whether the first allocation table or the second allocation table is used for the PUSCH transmission is determined based on a value of second information comprised in the DCI format.

12 . The communication method according to claim 11 , wherein
transmitting a RRC message comprising a second parameter(s) used for configuring whether or not the second information is present in the DCI format.
