An object of the present disclosure is to provide a radio-layer mechanism, which brings the IP and radio protocol layers closer and simplifies the radio protocols for future mobile networks, so that the extreme high transmission speed that these networks will be capable of may be efficiently utilized. The object is achieved by a method (900) in an access point adapted to schedule transmissions of packets to and/or from a radio communication device. The method comprising determining (910) radio resources needed for at least one packet to be sent to a radio communication device, scheduling (920) the at least one packet without segmentation on radio resources, whereby all the necessary amount of radio resources that a transmission of the at least one packet will need can be scheduled at a time, and transmitting (930) scheduling information indicating the scheduled resources to the radio communication device.
