Abstract
A radio device (110) and/or network node (105) support multiple HARQ processes. In particular, responsive to the radio device (110) receiving a resource grant for a first HARQ process, the radio device (110) starts or restarts a timer that configures the radio device (110) to monitor for a resource grant of a second HARQ process. Additionally or alternatively, the network node (105) transmits a resource grant for a first HARQ process and a resource grant for a second HARQ process to the same radio device (110).
Claims16
A method performed by a radio device for supporting multiple Hybrid Automatic Repeat Request (HARQ) processes, the method comprising:
- responsive to receiving a resource grant for a first HARQ process and determining that receiving a resource grant of a second HARQ process is possible according to one or more criteria, starting or restarting a timer that configures the radio device to monitor for the resource grant of the second HARQ process,
- the determining that receiving the resource grant of the second HARQ process is possible according to the one or more criteria comprises
- determining that the resource grant of the first HARQ process was received in order with respect to the second HARQ process;
- and
- wherein the first and second HARQ processes are both uplink HARQ processes or both being downlink HARQ processes.
A radio device for supporting multiple Hybrid Automatic Repeat Request (HARQ) processes, the radio device comprising:
- processing circuitry and communication circuitry communicatively coupled to the processing circuitry, wherein the processing circuitry is configured to:
- responsive to receiving a resource grant for a first HARQ process via the communication circuitry and determining that receiving a resource grant of a second HARQ process is possible according to one or more criteria, start or restart a timer that configures the radio device to monitor for the resource grant of the second HARQ process,
- the determining that receiving the resource grant of the second HARQ process is possible according to the one or more criteria comprising
- determining that the resource grant of the first HARQ process was received in order with respect to the second HARQ process;
- and
- wherein the first and second HARQ processes both being uplink HARQ processes or both being downlink HARQ processes.
A non-transitory computer readable medium storing a computer program product for controlling a programmable radio device, the computer program product comprising software instructions that, when run on the programmable radio device, cause the programmable radio device to:
- responsive to receiving a resource grant for a first HARQ process and determining that receiving a resource grant of a second HARQ process is possible according to one or more criteria, start or restart a timer that configures the radio device to monitor for the resource grant of the second HARQ process,
- the determining that receiving the resource grant of the second HARQ process is possible according to the one or more criteria comprising
- determining that the resource grant of the first HARQ process was received in order with respect to the second HARQ process;
- and
- wherein the first and second HARQ processes both being uplink HARQ processes or both being downlink HARQ processes.
