A method, performed by a user equipment (UE), for transmitting Buffer Status Reporting (BSR) information from the UE to a base station (BS) in a wireless telecommunication network, includes storing data to be transmitted, via a logical channel, in a transmission buffer, the logical channel being provided with a priority level and a specific Prioritized Bit Rate (PBR) parameter indicating a resource level to allocate to the UE for transmitting the stored data, wherein the BSR information represents an amount of data present in the transmission buffer of the UE, receiving new uplink data belonging to a logical channel for which no data already existed in the UE transmission buffer, and transmitting Buffer Status Reporting information upon receipt of the new uplink data.
