Abstract:
1. A method of supporting gated transmission of a fundamental channel assigned to a mobile station for communication with a first base station during soft handoff from the first base station to a second base station adjacent to the first base station in a mobile communication system, comprising the steps of: transmitting by the first base station to the second base station handoff request message including information whether the MS is transmitting data on the channel to the first base station in a reverse gating mode; determining by the second base station whether to support the reverse gating mode in data transmission on the channel from the MS to the second base station after the handoff in response to the handoff request message; transmitting by the second base station to the first base station a handoff request acknowledgement message including information whether the second base station provides the reverse gating mode and a reverse power control delay value indicating a transmission power control time point after the handoff; and transmitting by the first base station to the mobile station a handoff direction message including the information whether the second base station provides the reverse gating mode and the reverse power control delay value in response to the handoff request acknowledgement message.
