Abstract
When a base station has just a small amount of data to transmit to a served UE, the base station will transmit the data to the UE in a DCI message on a PDCCH, rather than using the DCI message to allocate PDSCH resources to carry the data and transmitting the data on the allocated PDSCH resources. Further, the base station could advantageously make use of a standard DCI message format but could transmit the data in DCI message fields that would otherwise be used to allocate PDSCH resources or otherwise to facilitate PDSCH transmission, since those DCI message fields would not be needed when the data is transmitted in the DCI message itself.
