Abstract
Various example embodiments relate to generation of coded transport blocks in connection with hybrid automatic repeat request (HARQ) process(es). A device may generate a plurality of protocol data units (PDU) for transmission. The PDUs may be stored in at least one HARQ buffer. The device may determine to transmit at least one coded transport based on identifying at least two of the PDUs for generating the coded transport block(s). Apparatuses, methods, and computer programs are disclosed.
Claims16
An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- generate a plurality of protocol data units for transmission;
- store the plurality of protocol data units in at least one hybrid automatic repeat request buffer;
- determine to transmit at least one coded transport block by combining at least two of the plurality of protocol data units, wherein the determination is based on one of:
- receiving a re-transmission grant that indicates one of a plurality of re-transmission modes and comprises a first identifier of a hybrid automatic repeat request process associated with the re-transmission grant, and
- receiving a transmission grant that comprises a second identifier of a hybrid automatic repeat request process and, in response determining that the second identifier belongs to a first set of hybrid automatic repeat request process identifiers;
- generate the at least one coded transport block based on the at least two of the plurality of protocol data units;
- and
- transmit the at least one coded transport block.

An apparatus, comprising:
- at least one processor;
- and
- at least one memory including computer program code;
- wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to:
- transmit a re-transmission grant, wherein the re-transmission grant indicates one of a plurality of re-transmission modes and at least one identifier of a hybrid automatic repeat request process associated with the re-transmission grant;
- in response to the transmitted re-transmission grant, receive at least one coded transport block generated based on a plurality of protocol data units, wherein the plurality of protocol data units is associated with the hybrid automatic repeat request process;
