FLEXIBLE SHORT TRANSMISSION TIME INTERVAL (TTI) RESOURCE ALLOCATION

Abstract:

A network node, wireless device and methods for short transmission time interval, sTTI, resource allocation in a communication network are provided. The network node includes processing circuitry configured to determine a downlink control information, DCI, message. The DCI message includes a bit field of at least two bits. Each bit corresponds to a group of at least one short Control Channel Element, sCCE, of a configured sPDCCH region. The processing circuitry is configured to transmit the DCI message to a wireless device. The bit field indicates whether the group of at least one sCCE is used for data transmission to the wireless device.
