Abstract

Facilitating notifications to indicate failed code block groups is provided herein. A method can comprise determining a value of a confirmation bit received in a transmission based on a first determination that a new data indicator is set to a null indication and performing an action from a group of actions. The group of actions can comprise decoding a first group of code block groups of the code block groups based on a second determination that the value of the confirmation bit for the first group of code block groups is a first value. The group of actions can also comprise decoding the code block groups based on a third determination that the value of the confirmation bit for the code block groups is set to a second value and sending a report indicating at least one of the code block groups for which the transmission failed.

Claims

1. A method, comprising:

setting, by a network device of a wireless network, the network device comprising a processor, one bit of information in a data stream to a defined value based on a receipt of a negative acknowledgement, from a mobile device, for a code block group after a first transmission of the code block group;

facilitating, by the network device, a second transmission of the data stream via a control channel, wherein the data stream comprises the one bit of information and the code block group, and wherein the one bit of information that is set to the defined value indicates the code block group is being re-transmitted in the second transmission for a decoding at the mobile device; and

sending, by the network device, configuration information that comprises information related to a quantity of code block groups for a codeword prior to the first transmission.

2. The method of claim 1, wherein the facilitating the second transmission comprises using implicit signaling to indicate the defined value of the one bit of information.

3. The method of claim 1, wherein the facilitating the second transmission comprises facilitating the transmitting of the code block group using a hybrid automatic repeat request process identifier that was used for the first transmission.

4. The method of claim 1, wherein the one bit of information is a first one bit of information, the data stream is a first data stream, the defined value is a first defined value, the code block group is a first code block group, and the method further comprises:

setting, by the network device, a second one bit of information in a second data stream to a second defined value based on a determination that a second code block group is to be transmitted to the mobile device; and

facilitating, by the network device, a third transmission comprising the second data stream via the control channel, wherein the second data stream comprises the second one bit of information and the second code block group, and wherein the second defined value indicates code block groups in the second code block group are to be decoded at the mobile device, and wherein the second code block group was not previously transmitted to the mobile device.

5. The method of claim 4, wherein the first defined value is a value of one and the second defined value is a value of zero.

6. The method of claim 4, wherein the facilitating the third transmission comprises facilitating the third transmission using a hybrid automatic repeat request at a transport block level.

7. The method of claim 1, further comprises configuring, by the network device, the mobile device with information related to a number of code block groups for a codeword prior to the first transmission.

8. The method of claim 7, wherein the configuring the mobile device comprises sending the information via a radio resource control layer.

9. The method of claim 7, wherein the configuring the mobile device comprises sending the information via a signaling layer that is higher than a radio resource control layer.

10. The method of claim 1, further comprising enabling, by the network device, a control block group based re-transmission through radio resource control signaling.

11. The method of claim 1, wherein the setting of the one bit of information comprises reducing a signaling overhead for a downlink control channel.

12. A method, comprising:

determining, by a mobile device comprising a processor, a value of a confirmation data received in a transmission based on a first determination that a new data indicator is set to a null indication, wherein the transmission comprises code block groups sent via a control channel; and

performing, by the mobile device, an action from a group of actions, the group of actions comprising;

decoding a first group of code block groups of the code block groups based on a second determination that the value of the confirmation data for the first group of code block groups is a first value, wherein the first group of code block groups are code block groups that failed to be received by the mobile device during a previous transmission, and wherein a second group of code block groups of the code block groups that did not fail to be received by the mobile device during the previous transmission are not decoded, and

decoding the code block groups based on a third determination that the value of the confirmation data for the code block groups is set to a second value;

sending a report indicating at least one of the code block groups for which the transmission failed; and

receiving configuration information that comprises information related to a quantity of code block groups for a codeword prior to receipt of the transmission.

13. The method of claim 12, wherein the determining the value of the confirmation data comprises:

determining the code block groups are received as a re-transmission based on the confirmation data being the first value; and

determining the code block groups are a new transmission based on the confirmation data being the second value.

14. The method of claim 12, wherein the first value is one and the second value is zero.

15. The method of claim 12, wherein the receiving the configuration information comprises receiving the configuration information via a radio resource control layer.

16. The method of claim 12, wherein the receiving the configuration information comprises receiving the configuration information via a signaling layer that is higher than a radio resource control layer.

17. The method of claim 12, wherein the control channel comprises a downlink control channel configured to operate according to a fifth generation wireless communication network protocol.

18. A non-transitory machine-readable storage medium, comprising executable instructions that, when executed by a processor, facilitate performance of operations, comprising:

determining a value of at least one bit received in a downlink transmission based on a first determination that a new data indicator is set to a null indication, wherein the downlink transmission comprises code block groups sent via a control channel;

in response to a second determination indicating that the value of the at least one bit for a first code block groups of the code block groups is a first value, decoding first code block groups of the code block groups, wherein the first code block groups are code block groups that failed during a previous transmission, and wherein second code block groups that did not fail to be received by a mobile device during the previous transmission are not decoded;

in response to the second determination indicating that the value of the at least one bit for the first code block groups is not the first value, decoding the code block groups based on a third determination that the value of the at least one bit for the code block groups is set to a second value;

sending a report indicating a failed code block group of the code block groups for which the downlink transmission failed; and

receiving configuration information that comprises information related to a quantity of code block groups for a codeword prior to receipt of the downlink transmission.

19. A non-transitory machine-readable storage medium of claim 18, wherein the control channel comprises a downlink control channel configured to operate according to a fifth generation wireless communication network protocol.
