Abstract
There is disclosed a method of operating a radio node in a Radio Access Network, RAN. The method includes transmitting, according to a transmission timing, a data element of a data stream associated to an acknowledgement signaling process. The transmission timing is determined based on a retransmission indication indicating whether the data element is to be transmitted the first time in the data stream, or is to be retransmitted in the data stream. The disclosure also pertains to related methods and devices.

A method of operating a radio node in a Radio Access Network, RAN, the method comprising:
- transmitting, according to a transmission timing, a data element of a data stream associated to an acknowledgement signaling process, the transmission timing being determined based on:
- a retransmission indication indicating whether one of:
- the data element is to be transmitted the first time in the data stream;
- and
- the data element is to be retransmitted in the data stream;
- and
- a comparison of a first redundancy indication corresponding to the data element to be transmitted the first time and a second redundancy indication corresponding to the data element to be retransmitted, at least one of the first and second redundancy indications pertaining to at least a size of the data element, the transmission timing indicating a transmission time interval in which to transmit the data element after reception of the retransmission indication.
A radio node for a Radio Access Network, RAN, the radio node comprising processing circuitry to configure the radio node to:
- transmit, according to a transmission timing, a data element of a data stream associated to an acknowledgement signaling process, the transmission timing being determined based on:
- a retransmission indication indicating whether one of:
- the data element is to be transmitted the first time in the data stream;
- and
- the data element is to be retransmitted in the data stream;
- and
- a comparison of a first redundancy indication corresponding to the data element to be transmitted the first time and a second redundancy indication corresponding to the data element to be retransmitted, at least one of the first and second redundancy indications pertaining to at least a size of the data element, the transmission timing indicating a transmission time interval in which to transmit the data element after reception of the retransmission indication.
A method of operating a radio node in a Radio Access Network, RAN, the method comprising:
- transmitting acknowledgement signaling associated to a data stream, the acknowledgement signaling comprising a retransmission indication, which indicates whether the data stream has been correctly received or not, the retransmission indication being determined based on associating, with the data stream, a data element received at a reception timing, the reception timing being determined based on:
- whether the data element is one of:
- scheduled for a first transmission in the data stream;
- and
- scheduled to be retransmitted in the data stream;
- and
- a comparison of a first redundancy indication corresponding to the data element scheduled for the first transmission and a second redundancy indication corresponding to the data element scheduled to be retransmitted, at least one of the first and second redundancy indications pertaining to at least a size of the data element, the reception timing indicating a reception time interval in which the data element is scheduled to be received after transmission of the acknowledgment signaling.
A radio node for a Radio Access Network, RAN, the radio node comprising processing circuitry to configure the radio node to:
- transmit acknowledgement signaling associated to a data stream, the acknowledgement signaling comprising a retransmission indication, which indicates whether the data stream has been correctly received or not, the retransmission indication being determined based on associating, with the data stream, a data element received at a reception timing, the reception timing being determined based on:
- whether the data element is one of:
- scheduled for a first transmission in the data stream;
- and
- scheduled to be retransmitted in the data stream;
- and
- a comparison of a first redundancy indication corresponding to the data element scheduled for the first transmission and a second redundancy indication corresponding to the data element scheduled to be retransmitted, at least one of the first and second redundancy indications pertaining to at least a size of the data element, the reception timing indicating a reception time interval in which the data element is scheduled to be received after transmission of the acknowledgment signaling.
