Abstract

A method for transmitting transmission block configuration parameter is provided. The method includes: sending first downlink control information (DCI) for scheduling a multi-transmission time interval transmission block, where the first DCI includes a preset indicator indicating that a configuration parameter that determines a transmission block size (TBS) of a retransmission TB scheduled by means of the first DCI is from the first DCI or second DCI, and the second DCI is DCI for scheduling a new transmission TB corresponding to the retransmission TB.

First claim

What is claimed is:

1. A method for transmitting transmission block configuration parameter, comprising:
sending first downlink control information (DCI) for scheduling a multi-transmission time interval transmission block, wherein the first DCI comprises a preset indicator indicating that a configuration parameter that determines a transmission block size (TBS) of a retransmission transmission block (TB) scheduled by the first DCI is from the first DCI or second DCI, and the second DCI is DCI for scheduling a new transmission TB corresponding to the retransmission TB.

2. The method according to claim 1 , wherein
the preset indicator indicates that a configuration parameter of a modulation and coding scheme (MCS) that determines the TBS of the retransmission TB scheduled by the first DCI is from the first DCI or the second DCI.

3. The method according to claim 2 , wherein
in response to determining that the preset indicator is a first value, the preset indicator indicates that the configuration parameter of the MCS that determines the TBS of the retransmission TB scheduled by the first DCI is from the first DCI; and
in response to determining that the preset indicator is a second value, the preset indicator indicates that the configuration parameter of the MCS that determines the TBS of the retransmission TB scheduled by the first DCI is from the second DCI.

4. The method according to claim 3 , further comprising:
setting the preset indicator as the second value in response to determining that the retransmission TB scheduled by the first DCI performs merged decoding with the new transmission TB.

5. The method according to claim 1 , wherein the first DCI further comprises: a new data indicator (NDI) indicating that the TB scheduled by the first DCI and transmitted by a physical uplink shared channel (PUSCH) resource is a retransmission TB or a new transmission TB.

6. A method for determining transmission block configuration parameter, comprising:
receiving first downlink control information (DCI) that schedules a multi-transmission time interval transmission block; and
obtaining, according to a preset indicator comprised in the first DCI, a configuration parameter that determines a transmission block size (TBS) of a retransmission transmission block (TB) scheduled by the first DCI from the first DCI or second DCI,
wherein the second DCI is-a DCI for scheduling a new transmission TB corresponding to the retransmission TB.

7. The method according to claim 6 , wherein obtaining, according to the preset indicator comprised in the first DCI, the configuration parameter that determines the TBS of the retransmission TB scheduled by the first DCI from the first DCI or second DCI comprises:
obtaining, according to the preset indicator comprised in the first DCI, a configuration parameter of a modulation and coding scheme (MCS) that determines the TBS of the retransmission TB from the first DCI or the second DCI.

8. The method according to claim 7 , wherein obtaining, according to the preset indicator comprised in the first DCI, the configuration parameter of the MCS that determines the TBS of the retransmission TB from the first DCI or the second DCI comprises:
obtaining the configuration parameter of the MCS that determines the TBS of the retransmission TB from the first DCI in response to determining that the preset indicator is a first value; and
obtaining the configuration parameter of the MCS that determines the TBS of the retransmission TB from the second DCI in response to determining that the preset indicator is a second value.

9. The method according to claim 6 , wherein the first DCI further comprises: a new data indicator (NDI), the NDI being used for indicating that the TB scheduled by the first DCI and transmitted by a physical uplink shared channel (PUSCH) resource is a retransmission TB or a new transmission TB.

10. A communication device, comprising a processor, a transceiver, a memory, and an executable program stored on the memory and executable by the processor, wherein the processor is configured to:
send first downlink control information (DCI) for scheduling a multi-transmission time interval transmission block, wherein the first DCI comprises a preset indicator indicating that a configuration parameter that determines a transmission block size (TBS) of a retransmission transmission block (TB) scheduled by the first DCI is from the first DCI or second DCI, and the second DCI is DCI for scheduling a new transmission TB corresponding to the retransmission TB.

11. The communication device according to claim 10 , wherein
the preset indicator indicates that a configuration parameter of a modulation and coding scheme (MCS) that determines the TBS of the retransmission TB scheduled by the first DCI is from the first DCI or the second DCI.

12. The communication device according to claim 11 , wherein
in response to determining that the preset indicator is a first value, the preset indicator indicates that the configuration parameter of the MCS that determines the TBS of the retransmission TB scheduled by the first DCI is from the first DCI; and
in response to determining that the preset indicator is a second value, the preset indicator indicates that the configuration parameter of the MCS that determines the TBS of the retransmission TB scheduled by the first DCI is from the second DCI.

13. The communication device according to claim 12 , wherein the processor is further configured to:
set the preset indicator as the second value in response to determining that the retransmission TB scheduled by the first DCI performs merged decoding with the new transmission TB.

14. The communication device according to claim 10 , wherein the first DCI further comprises: a new data indicator (NDI) indicating that the TB scheduled by the first DCI and transmitted by a physical uplink shared channel (PUSCH) resource is a retransmission TB or a new transmission TB.

15. A non-transitory storage medium, storing an executable program, wherein the executable program implements, when executed by a processor, steps of the method for transmitting transmission block configuration parameter according to claim 1 .

16. A non-transitory storage medium, storing an executable program, wherein the executable program implements, when executed by a processor, steps of the method for determining transmission block configuration parameter according to claim 6 .

17. A communication device, comprising a processor, a transceiver, a memory, and an executable program stored on the memory and executable by the processor, wherein the processor executes, when running the executable program, steps of the method for determining transmission block configuration parameter according to claim 6 .
