Abstract
In one embodiment, a method in a wireless device for adaptive HARQ retransmissions comprises receiving, from a network node, a request to initiate an adaptive hybrid automatic repeat request (HARQ) retransmission. The method comprises identifying a HARQ process associated with the HARQ retransmission request and determining whether a HARQ buffer of the HARQ process is empty. In response to determining that the HARQ buffer is empty, the method comprises not delivering the HARQ information to the HARQ process and not triggering an adaptive HARQ retransmission.
Claims20
A method in a wireless device for adaptive HARQ retransmissions, the method comprising:
- receiving, from a network node, a request to initiate an adaptive hybrid automatic repeat request (HARQ) retransmission, the HARQ retransmission request comprising HARQ information;
- identifying a HARQ process associated with the HARQ retransmission request;
- determining whether a HARQ buffer of the HARQ process is empty;
- and
- in response to determining that the HARQ buffer is empty:
- not delivering the HARQ information to the HARQ process;
- and
- not triggering an adaptive HARQ retransmission.
A wireless device for adaptive HARQ retransmission, comprising:
- an interface configured to receive, from a network node), a request to initiate an adaptive hybrid automatic repeat request (HARQ) retransmission, the HARQ retransmission request comprising HARQ information;
- and
- processing circuitry communicatively coupled to the interface, the processing circuitry configured to:
- identify a HARQ process associated with the HARQ retransmission request;
- determine whether a HARQ buffer of the HARQ process is empty;
- and
- in response to determining that the HARQ buffer is empty:
- not delivering the HARQ information to the HARQ process;
- and
- not triggering an adaptive HARQ retransmission.
A method performed by a network node for adaptive HARQ retransmissions in a communication network, the method comprising:
- determining that an uplink transmission from a wireless device was not received;
- transmitting an adaptive HARQ retransmission request to the wireless device;
- determining that an adaptive HARQ retransmission was not received from the wireless device;
- determining whether to transmit another adaptive HARQ retransmission request to the wireless device;
- and
- in response to determining that another adaptive HARQ retransmission request should not be sent to the wireless device, stopping additional adaptive HARQ retransmission requests to the wireless device.
A network node, comprising:
- processing circuitry configured to determine that an uplink transmission from a wireless device was not received;
- an interface communicatively coupled to the processing circuitry, the interface configured to transmit an adaptive HARQ retransmission request to the wireless device;
- and
- the processing circuitry further configured to:
- determine that an adaptive HARQ retransmission was not received from the wireless device;
- determine whether to transmit another adaptive HARQ retransmission request to the wireless device;
- and
- in response to determining that another adaptive HARQ retransmission request should not be sent to the wireless device, stopping scheduling of another adaptive HARQ retransmission requests to the wireless device.
