1. A method of scheduling data transmission of a group of wireless devices, in a wireless communication network, comprising:
determining a relative transmission timing relation between a reference wireless device out of the group of wireless devices and at least one wireless device out of the group of wireless devices; and
scheduling the data transmission of the at least one wireless device based on the indicated relative transmission timing relation in response to a scheduling request,
wherein the scheduling request comprises an information element and wherein the information element comprises at least an identity of the reference wireless device, a minimum and a maximum relative transmission timing relation between said reference wireless device and the at least one wireless device out of the group of wireless devices, and
wherein the minimum and maximum relative transmission timing relation between the reference wireless device and all wireless devices from said group of wireless devices are sent to a master wireless device out of the group of wireless devices,
sending the minimum and maximum relative transmission timing relation between the reference wireless device and the at least one wireless device to at least another wireless device, wherein the scheduling request is sent by each wireless device out of the group of wireless devices to at least one scheduler in the wireless communication network.
