Abstract

According to one aspect of the invention, in a radio communications system comprising at least one base station (BS1, BS2) provided with means for transmitting data via a communication link (BCCH; V), wherein the data is divided into a plurality of data packets and being transmitted via the communication link to at least one receiving station (UE). To reduce power consumption it is proposed that the downloading of the data packets is halted if it is determined that a data packet has not been received or a corrupted data packet has been received by the receiving station, the missing or corrupted data packet is retransmitted via the same or a different communication link at a later time.

Dependent claims

A method for downloading data in a radio communications system, the system including at least one base station with means for transmitting data via a communication link, the method which comprises:

dividing data into a plurality of data packets;
transmitting the data packets via the communication link to at least one receiving station;
halting a download of the data packets upon determining that a handover of the receiving station is due;
subsequently resuming the download of the data packets via a new communication link after a conclusion of the handover;
using a broadcast link to continue the download of data packets if a system load or a number of receiving stations exceed a predetermined threshold;
and
when the system load or the number of receiving stations lies below the predetermined threshold, using at least one dedicated channel to continue the download of data packets.
