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:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable to;

receive, by reception circuitry, a control channel including a Downlink Control Information (DCI) format; and

transmit, by transmission circuitry, 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 HARQ process number, 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 is indicated by the information for indicating the HARQ process number, the first value is determined based on the second value.

2. 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.

3. A base station device comprising:

a processor;

memory in electronic communication with the processor;

instructions stored in the memory, the instructions being executable to;

transmit, by transmission circuitry, a control channel including a Downlink Control Information (DCI) format; and

receive, by reception circuitry, 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, 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 is indicated by the information for indicating the HARQ process number, the first value is determined based on the second value.

4. The base station device according to claim 3, 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.
