Downlink control for ultra reliable communications

Abstract

For downlink control, a method receives by use of a processor, at User Equipment, a control channel with a first aggregation level in a Transmission Time Interval. The method attempts to decode the control channel. In response to the control channel being successfully decoded, the method determines a first downlink control information (DCI) with a first number of bits based on the received control channel; determines whether to decode the first DCI to determine a second DCI with a second number of bits based on the first DCI; and determines the second DCI with a second number of bits based on the decoded first DCI if determined to decode the first DCI. The method transmits data according to the second DCI if the second DCI is an uplink grant. The method receives data according to the second DCI if the second DCI is a downlink assignment.

What is claimed is: 
     
         1 . A method at a device, the method comprising:
 receiving a Semi-Persistent Scheduling (SPS) configuration for a first set of Physical Uplink Shared Chanel (PUSCH) transmissions;   receiving a downlink control information (DCI) scheduling a second Uplink (UL) transmission;   determining if any of the first set of PUSCH transmissions overlap with the second PUSCH transmission; and   in response to the determining a PUSCH transmission of the first set of PUSCH transmissions overlaps with the second UL transmission dropping the PUSCH transmission of the first set of PUSCH transmissions.
