Title: ADAPTING RESOURCE ELEMENT POWER CONTROL DYNAMIC RANGE IN DOWNLINK FOR SHORTENED TRANSMISSION TIME INTERVAL
Abstract:
A network node is provided. Processing circuitry of the network node is configured to configure a wireless device with a transmission time interval, TTI for use in operating a first physical channel. The physical channel includes a first reference radio resource. Determine the power control dynamic range scheme, the determination includes: if the TTI is greater than the threshold, selecting a first power control dynamic range for the first physical channel; and if the TTI is less than the threshold, selecting a second power control dynamic range for the first physical channel, the second power control dynamic range being different from the first power control dynamic range. A power for the first reference radio resource in the first power control dynamic range is the same as a power for the first reference radio resource in the second power control dynamic range.
