Resource allocation size dependent transport block size signaling

A method for transmitting a transport block and a related control channel in a mobile communication system, the method being performed by a transmitting apparatus and comprising:

• selecting for a transport block to be transmitted from a combination of a transport block size and resource allocation size out of plural predefined combinations of transport block size and resource allocation size, wherein the transport block sizes predefined by said combinations for a given resource allocation size have non-consecutive transport block size indices,
• determining, based on the selected combination of transport block size and resource allocation size, a transport block size indicator indicative of an offset to the minimum transport block size index yielded by the resource allocation size of said selected combination, and
• transmitting the transport block and a control channel comprising the transport block size indicator and a resource allocation size indicator indicative of the transport block size and resource allocation size of said selected combination.

A receiving apparatus for receiving a transport block in a mobile communication system, the receiving apparatus comprising:

• a receiver section that receives a control channel comprising a transport block size indicator and a resource allocation size indicator for a transmission of a transport block destined to the receiving apparatus,
• a processing section that determines a transport block size index based on the resource allocation size indicator and the transport block size indicator, wherein the resource allocation size indicator is determining the minimum or maximum transport block size index of a subset of non-consecutive transport block size indices of all available transport block size indices and the transport block size indicator determines the transport block size index from the subset of non-consecutive transport block size indices corresponding to the transport block size of the transport block, and
• an extraction section that extracts the transport block from the shared channel based on the resource allocation size indicator defining the number of resource blocks used to transmit the transport block and based on the selected transport block size index indicating the size of the transport block.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor of a receiving apparatus, cause the receiving apparatus to receive a transport block in a mobile communication system, by:

• receiving a control channel comprising a transport block size indicator and a resource allocation size indicator for a transmission of a transport block destined to the receiving apparatus, determining a transport block size index based on the resource allocation size indicator and the transport block size indicator, wherein the resource allocation size indicator is
• determining the minimum or maximum transport block size index of a subset of non-consecutive transport block size indices of all available transport block size indices and the transport block size indicator determines the transport block size index from the subset of non-consecutive transport block size indices corresponding to the transport block size of the transport block, and
• extracting the transport block from the shared channel based on the resource allocation size indicator defining the number of resource blocks used to transmit the transport block and based on the selected transport block size index indicating the size of the transport block.
