Abstract
The described technology is generally directed towards a composite HARQ-ACK response that contains information corresponding to a current HARQ-ACK composed with one or more previous HARQ-ACKs in a single uplink transmission. As a result, even with a HARQ-ACK repetition factor greater than one, the network is able to schedule the user equipment in consecutive time intervals as if the repetition factor was one (that is, as if no repetition).
Claims20
A method, comprising:
- selecting, by a user equipment comprising a processor, previous hybrid automatic repeat request acknowledgement data based on a repetition factor that defines a quantity for the previous hybrid automatic repeat request acknowledgement data;
- and
- transmitting, by the user equipment, to network equipment, a composite hybrid automatic repeat request acknowledgement response based on current hybrid automatic repeat request acknowledgement data corresponding to a current packet received by the user equipment and the previous hybrid automatic repeat request acknowledgement data corresponding to at least one previous packet received by the user equipment, wherein the transmitting comprises:
- in response to the repetition factor being determined to be greater than a threshold value, multiplexing the current hybrid automatic repeat request acknowledgement data with the previous hybrid automatic repeat request acknowledgement data to generate the composite hybrid automatic repeat request acknowledgement response, wherein the multiplexing comprises an interleaving operation, and
- in response to the repetition factor being determined not to be greater than the threshold value, bundling the current hybrid automatic repeat request acknowledgement data with the previous hybrid automatic repeat request acknowledgement data to generate the composite hybrid automatic repeat request acknowledgement response, wherein the bundling comprises an AND operation.

A user equipment, comprising:
- a processor;
- and
- a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising:
- choosing previous hybrid automatic repeat request acknowledgement data based on a repetition factor that defines a quantity for the previous hybrid automatic repeat request acknowledgement data;
- and
- sending, to network equipment, a composite hybrid automatic repeat request acknowledgement response based on current hybrid automatic repeat request acknowledgement data corresponding to a current packet received by the user equipment and the previous hybrid automatic repeat request acknowledgement data corresponding to at least one previous packet received by the user equipment, wherein the sending comprises:
- in response to the repetition factor being determined to be greater than a threshold value, multiplexing the current hybrid automatic repeat request acknowledgement data with the previous hybrid automatic repeat request acknowledgement data to create the composite hybrid automatic repeat request acknowledgement response, wherein the multiplexing comprises an interleaving operation, and
- in response to the repetition factor being determined not to be greater than the threshold value, bundling the current hybrid automatic repeat request acknowledgement data with the previous hybrid automatic repeat request acknowledgement data to create the composite hybrid automatic repeat request acknowledgement response, wherein the bundling comprises an AND operation.

A non-transitory machine-readable medium, comprising executable instructions that, when executed by a processor of a mobile device, facilitate performance of operations, comprising:
- selecting previous hybrid automatic repeat request acknowledgement data based on a repetition factor that defines a quantity for the previous hybrid automatic repeat request acknowledgement data;
- and
- communicating, to a network device, a composite hybrid automatic repeat request acknowledgement response based on current hybrid automatic repeat request acknowledgement data corresponding to a current packet received by the mobile device and the previous hybrid automatic repeat request acknowledgement data corresponding to at least one previous packet received by the mobile device, wherein the communicating comprises:
- in response to the repetition factor being determined to be greater than a threshold value, multiplexing the current hybrid automatic repeat request acknowledgement data with the previous hybrid automatic repeat request acknowledgement data to construct the composite hybrid automatic repeat request acknowledgement response, wherein the multiplexing comprises an interleaving operation, and
- in response to the repetition factor being determined not to be greater than the threshold value, bundling the current hybrid automatic repeat request acknowledgement data with the previous hybrid automatic repeat request acknowledgement data to construct the composite hybrid automatic repeat request acknowledgement response, wherein the bundling comprises an AND operation.
