1. Method carried out in a User Equipment (UE) for controlling uplink transmission of data to a base station of a wireless network, comprising:
transmitting, to the base station, a buffer status report (BSR) indicative of a data level value of a transmit buffer of the UE;
determining a packet arrival rate of data entering the transmit buffer, wherein the packet arrival rate is determined at a point in time between transmission of said BSR and a preceding BSR, or concurrently with obtaining the data level value;
transmitting, to the base station, information indicative of the packet arrival rate;
receiving uplink resource information from the base station, in response to the BSR and said information; and
transmitting data from the buffer using the received resource information.
