Claim of US Patent No. 10,368,343

1. A method of operation of a network node in a cellular communications network, comprising:transmitting a downlink assignment to a wireless device, the downlink assignment comprising an indication of whether the downlink assignment applies to a single transmit time interval or multiple consecutive transmit time intervals;
transmitting a downlink data transmission to the wireless device during a single transmit time interval or multiple downlink data transmissions to the wireless device during multiple consecutive transmit time intervals according to the downlink assignment where the multiple downlink data transmissions comprise at least two different data values;
determining whether the wireless device supports multiple transmit time interval downlink assignment;
determining whether a service type of a service associated with the downlink transmission to the wireless device is a guaranteed bit rate service type; and
upon determining that the wireless device supports multiple transmit time interval downlink assignment and determining that the service type of the service associated with the downlink transmission to the wireless device is a guaranteed bit rate service type:
determining a number of consecutive transmit time intervals to be scheduled for downlink data transmission to the wireless device, the determined number of consecutive transmit time intervals being greater than or equal to 1; and
scheduling the multiple downlink data transmissions to the wireless device during the determined number of consecutive transmit time intervals.
