Abstract:
1. A method, performed by a user equipment (TYE), for transmitting Buffer Status Reporting (BSR) information from the UE to a base station (BS) in a wireless telecommunication network, said method comprising: 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 said BSR information represents an amount of data present in the transmission buffer of the UE; receiving new uplink data; determining whether said new uplink data belongs to a logical channel for which no data already existed in the UE transmission buffer and for which a non null PBR is defined; and the transmitting of the BSR information upon receipt of said new uplink data in dependence on said determination, wherein the transmission of the BSR information is triggered when said new uplink data belongs to a logical channel, respectively to a channel of a group of logical channels, having a non null PBR value and a priority level lower than that of a logical channel, respectively than that of a group of logical channels, for which the buffer already contains data to transmit, and for which sufficient resources have already been allocated by the base station to the UE.
