  • Method and device for scheduling of feedback
    Patent number: 9960897
    Abstract: The present disclosure provides a method in a communication device for scheduling of feedback. The method includes determining, for a data transmission, a resource element to be scheduled for a feedback signal being responsive to the data transmission. The resource element is determined to be within a feedback time limit. The feedback time limit indicates a maximum allowable time period between transmitting the data transmission and receiving the feedback signal. The feedback time limit is dependent on a type of resource allocated to the data transmission and/or a type of traffic associated with the data transmission. The method further includes transmitting, to a wireless device, a feedback scheduling instruction indicating the resource element.
