DATA INDICATOR FOR DCI SCHEDULING MULTIPLE CELLS: abstract simplified (18018620)

• This abstract for appeared for patent application number 18018620 Titled 'DATA INDICATOR FOR DCI SCHEDULING MULTIPLE CELLS'

Simplified Explanation

This abstract describes a method for operating a network node in a wireless communication system. The network node configures a message called downlink control information (DCI) to schedule communication with a user equipment (UE) in multiple serving cells. The DCI message does not include a specific field called new data indicator (NDI) for at least one of the serving cells. The network node then transmits this DCI message to the UE. On the UE side, it receives the DCI message which schedules communication in multiple serving cells. The DCI message also does not include an explicit NDI field for a specific serving cell. In response, the UE determines the NDI value associated with the scheduled communication for that serving cell or identifies if there is a new data transmission scheduled for that serving cell.

Original Abstract Submitted

A method of operating a network node in a wireless communication system includes configuring a downlink control information (DCI) message that schedules uplink or downlink communications with a user equipment (UE) in a plurality of serving cells. The DCI message does not include an explicit new data indicator (NDI) field for at least one of the serving cells scheduled by the DCI message. The network node transmits the DCI message to the UE. A method performed by a UE includes receiving a DCI message that schedules uplink or downlink communications in a plurality of serving cells. The DCI message does not include an explicit NDI field for a serving cell scheduled by the DCI message. In response, the UE determines an NDI value associated with scheduled communications for the serving cell or determines that the scheduled communications for the serving cell contains a new data transmission.
