Abstract
A system and method is provided which allows for the dynamic interpretation of a transport block size field in a Layer 1/Layer 2 (L1/L2) control channel, such that for any first H-ARQ transmission, the transport block size indication field will indicate the size of the transport block. For any retransmission, the transport block size indication bits can be transformed into dedicated bits for indicating the RV used as it relates to circular buffering. A robust bit field for indicating new data transmission (e,g, new data indication (NDI)) is therefore introduced, and from a UE perspective it is possible to determine how to interpret the transport block size field.

A method of signaling, comprising:
- receiving control channel data;
- determining whether the control channel data is at least one of:
- a retransmission, new data and a first transmission;
- and
- dynamically interpreting the control channel data based on the determination,
- wherein the control channel data includes a transport block size field,
- wherein the transport block size field is interpreted as indicative of a transport block size in response to determining that the control channel data is at least one of:
- new data and a first transmission, and
- wherein the transport block size field is interpreted as indicative of a redundancy version in response to determining that the control channel data is a retransmission.
An apparatus, comprising:
- a processor;
- and
- a memory unit communicatively connected to the processor and including:
- computer code configured to receive control channel data;
- computer code configured to determine whether the control channel data is at least one of:
- a retransmission, new data and a first transmission;
- and
- computer code configured to dynamically interpret the control channel data based on the determination,
- wherein the control channel data includes a transport block size field, wherein the transport block size field is interpreted as indicative of a transport block size in response to determining that the control channel data is at least one of:
- new data and a first transmission, and
- wherein the transport block size field is interpreted as indicative of a redundancy version in response to determining that the control channel data is a retransmission.
A system, comprising:
- a transmitter configured to encode a signal and transmit the signal;
- and
- a receiver configured to receive the signal, to determine whether the signal is at least one of:
- a retransmission, new data and a first transmission and to decode the signal, wherein the decoding of the signal is performed at least by dynamically interpreting control channel data based on the determination,
- wherein the control data includes a transport block size field,
- wherein the transport block size field is interpreted as indicative of a transport block size in response to determining that the signal is at least one of new data and a first transmission, and
- wherein the transport block size field is interpreted as indicative of a redundancy version in response to determining that the signal is a retransmission.
A method, comprising:
- encoding a data signal;
- and
- transmitting control channel data associated with the encoded data signal, the control channel data being configured to be dynamically interpreted,

- wherein the transport block size field is indicative of a transport block size when transmitting at least one of:
- new data and a first transmission, and
- wherein the transport block size field is indicative of a redundancy version when transmitting a retransmission.
