FIELD: radio engineering, communication.
SUBSTANCE: allocation of downlink resources, in which data on 1 layers are monitored, is received. A resource-specific bit (ACK/NACK) is generated for each of those resources. From a pattern of said resources, an algorithm is selected from a first algorithm that bundles resources in a first mode and a second algorithm that bundles resources in a second mode. The selected algorithm is used on the resource-specific bits that correspond to the downlink resources, bundled according to the selected mode, to generate l reply bits which are then transmitted. At the network side a NACK reply bit is received, and based on a pattern of the allocated downlink resources, a first algorithm that bundles resources in a first mode or a second algorithm that bundles resources in a second mode is selected. A bundling window and layer combination which gives the resource for retransmitting the NACK data is determined from the selected algorithm.
EFFECT: providing correct interpretation of data transmitted between eNB and UE, while selecting the same mode of bundling resources at both ends of the transmitting/receiving link.
