Systems and methods for downlink scheduling that mitigate PDCCH congestion
Abstract:
Systems and methods are disclosed for improving Physical Downlink Control Channel (PDCCH) allocation for improved downlink scheduling. In some embodiments, a method of operation of a network node in a cellular communications network comprises 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 (TTI) or multiple consecutive TTIs, and transmitting a downlink data transmission to the wireless device during a single TTI or multiple downlink data transmissions to the wireless device during multiple consecutive TTIs according to the downlink assignment. In this manner, the network node does not need to transmit, and the wireless device does not need to receive/decode, a separate downlink assignment in each TTI. This may be beneficial to, e.g., mitigate PDCCH congestion.
