ABSTRACT:
The transmission of high-speed data traffic in IPDLs at a base station of a cellular communications network is controlled. An IPDL is identified which occurs within a set of time slots of a given channel. The channel may comprise a dedicated time slot channel or a packet-oriented time slot channel. More specifically, the channel may comprise a Dedicated Physical Control Channel or a High Speed Downlink Shared Channel. The information within a time slot of the set is shifted. In accordance with one aspect of the invention, the information is shifted to a reduced portion of the time slot of the channel by reducing a spread spectrum factor for the signal carrying the information and increasing the transmission power of the signal. A remaining portion of the time slot spans at least a duration of the identified IPDL. In accordance with another aspect of the invention, the information within the time slot is shifted to another time slot of the channel.
