Abstract

A terminal device receives a control channel containing a DCI format and transmits a PUSCH. The DCI format contains an uplink index and information indicating a HARQ process number; the PUSCH transmission is adjusted to a first sub-frame when the first bit of the uplink index is set to 1; the PUSCH transmission is adjusted to a second sub-frame when the second bit of the uplink index is set to 1; and the HARQ process number of the PUSCH corresponding to the second bit is assigned on the basis of at least the information indicating the HARQ process number and whether or not both the first bit and the second bit are set to 1.

Claims

1. A terminal device comprising:

reception circuitry configured and/or programmed to receive a control channel including a Downlink Control Information (DCI) format; and

transmission circuitry configured and/or programmed to transmit a Physical Uplink Shared Channel (PUSCH),

wherein the DCI format includes an uplink index and information for indicating a Hybrid Automatic Repeat reQuest (HARQ) process number,

the transmission circuitry, in a case that a first bit of the uplink index is set to 1, adjusts the PUSCH transmission to a first subframe,

the transmission circuitry, in a case that a second bit of the uplink index is set to 1, adjusts the PUSCH transmission to a second subframe, and

the HARQ process number of the PUSCH corresponding to the second bit is determined based on at least whether or not both the first bit and the second bit are set to 1 and the information for indicating the process number.

7. The terminal device according to claim 1, wherein, the first bit of the uplink index and the second bit of the uplink index being different from a bit of the information for indicating the HARQ process number.

8. The terminal device according to claim 1, wherein, in a case that both the first bit of the uplink index and the second bit of the uplink index are set to 1, the HARQ process number of the PUSCH corresponding to the second bit being a first value different from a second value indicated by the information for indicating the HARQ process number, the first vale is determined based on the second value.

2. A base station device comprising:

transmission circuitry configured and/or programmed to transmit a control channel including a Downlink Control Information (DCI) format; and

reception circuitry configured and/or programmed to receive a Physical Uplink Shared Channel (PUSCH),

wherein the DCI format includes an uplink index and information for indicating a Hybrid Automatic Repeat reQuest (HARQ) process number,

in a case that a first bit of the uplink index is set to 1, the MSG transmission is adjusted to a first subframe,

in a case that when a second bit of the uplink index is set to 1, the PUSCH transmission is adjusted to a second subframe, and

the HARQ process number of the PUSCH corresponding to the second bit is determined based on at least whether or not both the first bit and the second bit are set to 1 and the information for indicating the HARQ process number.

9. The base station device according to claim 2, wherein, the first bit of the uplink index and the second hit of the uplink index being different from a bit of the information for indicating the HARQ process number.

10. The base station device according to claim 2, wherein, in a case that both the first bit of the uplink index and the second hit of the uplink index are set to 1, the HARQ process number of the PUSCH corresponding to the second hit being a first value different from a second value indicated by the information for indicating the HARQ process number, the first vale is determined based on the second value.

3. A communication method for a terminal device, the communication method comprising:

receiving a control channel including a Downlink Control Information (DCI) format; and

transmitting a Physical Uplink Shared Channel (PUSCH),

wherein the DCI format includes an uplink index and information for indicating a Hybrid Automatic Repeat reQuest (HARQ) process number,

in a case that a first bit of the uplink index is set to 1, the PUSCH transmission is adjusted to a first subframe,

in a case that a second bit of the uplink index is set to 1, the PUSCH transmission is adjusted to a second subframe, and

the HARQ process number of the PUSCH corresponding to the second bit is determined based on at least whether or not both the first bit and the second bit are set to 1 and the information for indicating the HARQ process number.

4. A communication method for a base station device, the communication method comprising:

transmitting a control channel including a Downlink Control Information (DCI) format; and

receiving a Physical Uplink Shared Channel (PUSCH),

wherein the DCI format includes an uplink index and information for indicating a Hybrid Automatic Repeat reQuest (HARQ) process number,

in a case that a first bit of the uplink index is set to 1, the PUSCH transmission is adjusted to a first subframe,

in a case that second bit of the uplink index is set to 1, the PUSCH transmission is adjusted to a second subframe, and

the HARQ process number of the PUSCH corresponding to the second bit is determined based on at least whether or not both the first bit and the second bit are set to 1 and the information for indicating the HARQ process number.
