Probing for Increased Capacity in Reliable Low-Latency Communication

A method performed in a receiving node of radio network for processing quality information on transport blocks, the method comprising the steps of:

• receiving a first transport block using a set of transport transmission properties;
• receiving a probing block, said probing block using a set of probing transmission properties having a reduced transmission robustness in relation to the set of transport transmission properties used for the first transport block;
• communicating an acknowledgment in response to decoding of the probing block;
• and
• discarding the decoded probing block.

A transmitting node in a radio network comprising:

• processing circuitry comprised of at least one processing unit and at least one memory, wherein the processing circuitry is configured as a plurality of modules including:
• a data module configured to provide a first and a second transport block comprising payload data using a set of transport transmission properties;
• a probing module configured to provide a probing block using a set of probing transmission properties, said probing transmission properties having a reduced transmission robustness in relation to the set of transport transmission properties;
• a communication module configured to transmit the first and second transport blocks and the probing block in between the transmission of the first and second transport blocks to a receiving node;
• a transmission property module configured to reconfigure the set of transport transmission properties in response to a success acknowledgment for decoding of the probing block provided by the receiving node.

A receiving node in a radio network comprising:

• processing circuitry comprised of at least one processing unit and at least one memory, wherein the processing circuitry is configured as a plurality of modules including:
• a decoding module configured to decode a first transport block and a second transport block, using a set of transport transmission properties, to retrieve payload data;
• a probing module configured to:
• decode a probing block using a set of probing transmission properties having a reduced transmission robustness in relation to the set of transport transmission properties,
• discard the probing block after decoding, and
• provide an acknowledgment indicative to a decoding result of the probing block;
• a communication module configured to receive the first and second transport blocks and the probing block in between the first and second transport blocks from a transmitting node and transmit the acknowledgment to said transmitting node.
