Arrangement for Reliable Relaying

A terminal device comprising:

• at least one processor;
• and
• at least one non-transitory memory including computer program code;
• the at least one memory and the computer program code configured, with the at least one processor, to cause the terminal device at least to perform:
• in response to receiving configuration information from an access node, configuring the terminal device based on the configuration information;
• decoding any received primary uplink resources according to a configuration of the terminal device;
• and
• in response to decoding of a primary uplink resource being successful, causing transmitting a transport block corresponding to the decoded primary uplink resource on a secondary uplink resource using a pre-defined starting position to a target network node according to the configuration, wherein the target network node is the access node or a terminal device.

A method comprising:

• selecting one or more terminal devices connected to an access node for relaying a signal from the source terminal device to the access node based at least on radio link measurements;
• configuring, by generating configuration information and causing transmitting the configuration information, each of the one or more terminal devices to
• decode each received primary uplink resource, and
• if the decoding is successful, causing transmitting a transport block corresponding to the decoded primary uplink resource on a secondary uplink resource using a pre-defined starting position to a target network node, wherein the one or more terminal devices are configured by the access node to use different secondary uplink resources and different pre-defined starting positions and the target network node is the access node or one of the one or more terminal devices, at least one terminal device being configured by the access node to use the access node as the target network node;
• and
• receiving at least one transport block transmitted from the source terminal device via one or more terminal devices of the one or more terminal devices on one or more secondary uplink resources.

A method comprising:

• in response to receiving configuration information from an access node, configuring a terminal device based on the configuration information;
• decoding any received primary uplink resources according to a configuration of the terminal device;
• and
• in response to decoding of a primary uplink resource being successful, causing transmitting a transport block corresponding to the decoded primary uplink resource on a secondary uplink resource using a pre-defined starting position to a target network node according to the configuration, wherein the target network node is the access node or a terminal device.
