It is presented methods and apparatuses for uplink resource utilization in a telecommunication system. More particularly, embodiments disclosed herein relate to a method performed in a user equipment (4), said user equipment (4) having data (Di) ready to transmit, the data pertaining to a traffic class (i). The method comprises establishing a connection with a radio network node (2) and receiving threshold parameter sets (Thi) from the radio network node (2). Each threshold parameter set (Thi) comprising at least a minimum size limit (Si) associated with respective traffic class (i). The threshold parameter sets (Thi) are used to determine if the amount of data that the user equipment (4) has ready to transmit is large enough to be transmitted or if it has been waiting long enough to be transmitted. If it is the UE (4) transmits the data to the radio network node (2). There are also presented a corresponding method performed in the network node (2) and a user equipment (4) and a network node (2) for performing the methods.
