1. A method performed by a wireless access node for triggering a wireless device to provide feedback to communication resource allocations transmitted from the wireless access node, comprising:
generating a downlink control message comprising:
a set of wireless downlink communication resource allocations; and
a plurality of allocation feedback control fields comprising:
a resource group ID field identifying a current allocation group for the set of wireless downlink communication resource allocations among a plurality of allocation groups;
a feedback triggering group indicator specifying a set of triggering allocation groups among the plurality of allocation groups that the wireless device is to be triggered to provide the feedback; and
a feedback timing indicator specifying a timing control information for triggering the feedback from the wireless device, wherein the timing control information comprises a non-numerical value for indicating to the wireless device to delay providing the feedback, and wherein a number of times that the feedback timing indicator for next downlink control messages having the resource group ID field as the current allocation group is the non-numerical value is limited to a predefined maximum number before all pending and unacknowledged wireless downlink communication resource allocations in the current allocation group are acknowledged by the wireless device; and
transmitting the downlink control message to the wireless device to control the wireless device in providing the feedback with respect to all the pending and unacknowledged wireless downlink communication resource allocations belonging to the set of triggering allocation groups according to the feedback timing indicator.
