ABSTRACT:
A method of scheduling uplink transmissions from a plurality of source user equipments to a base station is disclosed. The method comprises the steps of determining the amount of data in the data buffer of each of the user equipments, comparing the amount of data in the data buffers of the user equipments to obtain, for each user equipment, a relative indicator, the relative indicator indicating how full that user equipment's data buffer is in comparison to the data buffers of the other user equipments, and scheduling uplink transmissions in dependence on the relative indicators. In this way, each user equipment is given some knowledge of the state of the buffer in the other user equipments. The user equipments are therefore able to make more efficient scheduling decisions. This can improve the throughput and give lower packet delivery delays.
