Abstract

Certain aspects of the present disclosure are generally directed to monitoring different decoding candidates assuming different encoding schemes. For example, certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes determining a first encoding scheme used to encode first downlink control information (DCI) and a second encoding scheme used to encode second DCI, and monitoring one or more first decoding candidates for the first DCI based on the first encoding scheme and one or more second decoding candidate for the second DCI based on the second encoding scheme.

Claims

1. A method for wireless communication, comprising:

determining a first encoding scheme used to encode first downlink control information (DCI) and a second encoding scheme used to encode second DCI; and

monitoring one or more first decoding candidates for the first DCI based on the first encoding scheme and one or more second decoding candidates for the second DCI based on the second encoding scheme.

2. The method of claim 1, wherein the determination is based on a type of search space corresponding to the one or more first decoding candidates or the one or more second decoding candidates.

3. The method of claim 2, wherein the type of search space comprises a user-equipment specific search space (UESS) or a common search space (CSS).

4. The method of claim 2, wherein the type of search space comprises a search space for a first type of service or a search space for a second type of service.

5. The method of claim 1, wherein the determination is based on a size or format of the first DCI or the second DCI, or a combination of the size and the format.

6. The method of claim 1, wherein the determination is based on a type of radio network temporary identifier (RNTI) associated with the first DCI or the second DCI.

7. The method of claim 6, wherein the determination is based on whether the type of RNTI is user-equipment (UE) specific.

8. The method of claim 1, wherein the determination is based on a duration of a control channel used to transmit the first DCI or the second DCI.

9. The method of claim 1, wherein the determination is based on whether a control channel used to transmit the first DCI or the second DCI is transmitted using channel repetition.

10. The method of claim 9, wherein the first encoding scheme comprises tail-biting convolution code (TBCC) if the control channel used to transmit the first DCI uses channel repetition.

11. The method of claim 1, wherein the determination is based on a component carrier (CC) used to transmit the first DCI or the second DCI.

12. The method of claim 1, further comprising:

determining a third encoding scheme based on the determination of the first encoding scheme or the second encoding scheme; and

decoding a data channel based on the third encoding scheme.

13. The method of claim 11, wherein determining the third encoding scheme is further based on a payload range of the data channel.

14. The method of claim 1, wherein the first encoding scheme comprises tail-biting convolution code (TBCC) and the second encoding scheme comprises polar coding.

15. The method of claim 1, further comprising receiving an indication of a policy for determining an encoding scheme, wherein the determination is based on the indication.

16. The method of claim 1, wherein the method is performed by a user equipment (UE), and wherein the determination is based on a capability or a category of the UE.
