Abstract
A method and apparatus communicate a transport block in an unlicensed uplink transmission on a wireless network. Downlink Control Information (DCI) can be sent on a control channel. The DCI can schedule an unlicensed uplink (UL) transmission for a UE. The DCI can include a field that indicates whether the UE should apply a scaling factor when determining a Transport Block Size (TBS). A transport block can be received in the unlicensed UL transmission based on the sent DCI.
Claims17
An apparatus comprising:
- a controller that controls operations of the apparatus;
- and
- a transceiver that
- sends downlink control information (DCI) on a control channel, the DCI scheduling an unlicensed uplink transmission for a user equipment (UE), and
- receives a transport block in the unlicensed uplink transmission based on the sent DCI,
- wherein the DCI comprises a modulation and coding scheme field,
- wherein a value in the modulation and coding scheme field in the DCI indicates whether a size of the transport block is determined from an earlier DCI transmitted for the same transport block.
An apparatus comprising:
- a transceiver configured to receive downlink control information (DCI) on a control channel, the DCI scheduling an unlicensed uplink transmission for the apparatus;
- and
- a controller coupled to the transceiver, the controller configured to determine a transport block size for the unlicensed uplink transmission,
- wherein the transceiver is configured to transmit a transport block in the unlicensed uplink transmission based on the received DCI,
- wherein the DCI comprises a modulation and coding scheme field, and
- wherein a value in the modulation and coding scheme field in the DCI indicates whether the transport block size is determined from an earlier DCI received for the same transport block.
A method in a user equipment (UE), the method comprising:
- receiving downlink control information (DCI) on a control channel, the DCI scheduling an unlicensed uplink transmission for the UE;
- and
- determining a transport block size for the unlicensed uplink transmission;
- and
- transmitting a transport block in the unlicensed uplink transmission based on the received DCI,
- wherein the DCI comprises a modulation and coding scheme field, and
- wherein a value in the modulation and coding scheme field in the DCI indicates whether the transport block size is determined from an earlier DCI received for the same transport block.
