Abstract

The present invention provides methods and apparatus for a wireless system, broadcasting a plurality of data packets to at least one wireless terminal (115). The wireless system comprises a plurality of base stations (103, 105) that interfaces to a backbone network (107) in order to receive the plurality of data packets from a service source (101). Data packets are sent to a wireless terminal by a first base station transmitting a first channel burst and by a second base station transmitting a second channel burst, in which corresponding time offsets of the channel bursts, as characterized by amounts phase shifts, are different. Consequently, when the wireless terminal executes a handover from the first base station to the second base station, a probability that some of the data packets are lost, as result of practical network considerations, is reduced.
