Abstract

Claims (50)

1. A user equipment (UE) comprising:

at least one processor; and

at least one non-transitory computer-readable medium storing one or more instructions that, when executed by the at least one processor, cause the UE to:

receive a radio resource control (RRC) configuration from a base station (BS);

determine whether a first parameter is configured in the RRC configuration;

receive, from the BS, a command that indicates disabling a Hybrid Automatic Repeat Request (HARQ) feedback for a specific HARQ process;

receive first downlink control information (DCI) from the BS, the first DCI including a first field indicating a first HARQ process identifier (ID);

determine that a number of bits in the first field is a default number in a case that the first parameter is not configured in the RRC configuration;

determine that the number of bits in the first field is a specific number greater than the default number in a case that the first parameter is configured in the RRC configuration;

receive, from the BS, a first Physical Downlink Shared Channel (PDSCH) associated with the specific HARQ process; and

receive, from the BS, a second PDSCH associated with the specific HARQ process before an end of an expected transmission of the HARQ feedback for the specific HARQ process, the second PDSCH including a retransmission of a Transport Block (TB) transmitted in the first PDSCH.

2. The UE of claim 1 , wherein the command is received via an RRC message.

3. The UE of claim 2 , wherein the RRC message indicates an ID of the specific HARQ process.

4. The UE of claim 1 , wherein the one or more instructions, when executed by the at least one processor, further cause the UE to:

receive, from the BS, a Channel State Information (CSI) report configuration that includes a second parameter for indicating a polarization mode.

5. The UE of claim 4 , wherein the one or more instructions, when executed by the at least one processor, further cause the UE to:

determine a Channel Quality Indicator (CQI) based on the CSI report configuration, wherein the CQI has different values depending on a value of the second parameter.

6. The UE of claim 1 , wherein the specific number is 5.

7. The UE of claim 1 , wherein the first DCI comprises one of a DCI format 0_1 and a DCI format 1_1.

8. The UE of claim 1 , wherein:

the first DCI comprises a DCI format 0_1; and

the one or more instructions, when executed by the at least one processor, further cause the UE to:

determine whether a second parameter is configured in the RRC configuration;

receive second DCI having a DCI format 1_1 from the BS, the second DCI including a second field indicating a second HARQ process ID;

determine that a number of bits in the second field is the default number in a case that the second parameter is not configured in the RRC configuration; and

determine that the number of bits in the second field is the specific number in a case that the second parameter is configured in the RRC configuration.

9. A method for wireless communication performed by a user equipment (UE), the method comprising:

receiving a radio resource control (RRC) configuration from a base station (BS);

determining whether a first parameter is configured in the RRC configuration;

receiving, from the BS, a command that indicates disabling a Hybrid Automatic Repeat Request (HARQ) feedback for a specific HARQ process;

receiving first downlink control information (DCI) from the BS, the first DCI including a first field indicating a first HARQ process identifier (ID);

determining that a number of bits in the first field is a default number in a case that the first parameter is not configured in the RRC configuration;

determining that the number of bits in the first field is a specific number greater than the default number in a case that the first parameter is configured in the RRC configuration;

receiving, from the BS, a first Physical Downlink Shared Channel (PDSCH) associated with the specific HARQ process; and

receiving, from the BS, a second PDSCH associated with the specific HARQ process before an end of an expected transmission of the HARQ feedback for the specific HARQ process, the second PDSCH including a retransmission of a Transport Block (TB) transmitted in the first PDSCH.

10. The method of claim 9 , wherein the command is received via an RRC message.

11. The method of claim 10 , wherein the RRC message indicates an ID of the specific HARQ process.

12. The method of claim 9 , further comprising:

receiving, from the BS, a Channel State Information (CSI) report configuration that includes a second parameter for indicating a polarization mode.

13. The method of claim 12 , further comprising:

determining a Channel Quality Indicator (CQI) based on the CSI report configuration, wherein the CQI has different values depending on a value of the second parameter.

14. The method of claim 9 , wherein the specific number is 5.

15. The method of claim 9 , wherein the first DCI comprises one of a DCI format 0_1 and a DCI format 1_1.

16. The method of claim 9 , wherein:

the first DCI comprises a DCI format 0_1; and

the method further comprises:

determining whether a second parameter is configured in the RRC configuration;

receiving second DCI having a DCI format 1_1 from the BS, the second DCI including a second field indicating a second HARQ process ID;

determining that a number of bits in the second field is the default number in a case that the second parameter is not configured in the RRC configuration; and

determining that the number of bits in the second field is the specific number in a case that the second parameter is configured in the RRC configuration.
