A network node comprised in a wireless communication network is for managing allocation of uplink resources regarding remaining data blocks of an uplink transmission performed by a device. The network node sends, to the device, first allocation information that identifies uplink resources that have been allocated to the device for uplink transmission of said remaining data blocks. The remaining data blocks being associated with the allocated uplink resources, respectively. The network node also sends, to the device, and the device receives, a second allocation information that identifies one or more of said allocated uplink resources identified by the first allocation information, wherein said second allocation information further identifies one or more of said remaining data blocks as data blocks to be excluded by the device.

A method, node, and system are provided that overcome problems with using inaccurate estimates of a current round trip time RTT for verifying the ACK/NACK information received in an ACK/NACK report, e.g., a piggy-backed ACK/NACK (PAN). This is accomplished by de-coupling the RTT from the ACK/NACK analysis performed in the sending node that receives the ACK/NACK report. As a result, unnecessary re-transmissions are avoided, communication delays are decreased, and spectrum and other system resources are used more efficiently.
