Abstract
A radio telecommunications system and method of operating the same is described which provides a reduce delay for transfer of packet data. Before a data transmission is released in one direction (uplink or downlink) a channel is reserved in the other direction. The channel reservation may be held for a certain period of time, e.g. 5 seconds after which the channel is released. The present invention is particularly useful when there is a large asymmetry in data transfer between uplink and downlink.
