Abstract
A method and apparatus for controlling transmission of an RPC channel during a handoff in a mobile communication system, wherein. only one AN is selected among a plurality of ANs to transmit reverse power control information to an AT. For this purpose, a Forward Link Selection message received at an AN from an RNC. Alternatively, a DRC cover received at an AN from AT can be used. The DRC cover indicates at least one of ANs excluding an AN having the worst chennel condition for the AT.
Claims29
A method of controlling transmission of reverse power control information in a mobile communication system having an AT (Access Terminal), a plurality of ANs (Access Networks) in an active set communicable with the AT at soft handoff, and an RNC (Radio Network Controller) connected to the plurality of ANs, comprising the steps of:
- selecting at least one of the ANs excluding an AN having the worst channel condition for the AT;
- and
- transmitting reverse power control (RPC) information from only the selected AN to the AT.
A method of controlling transmission of reverse power control information in an AN (Access Network) of a mobile communication system having an AT (Access Terminal), a plurality of ANs in an active set communicable with the AT during soft handoff, and an RNC (Radio Network Controller) connected to the plurality of ANs, comprising steps of:
- receiving a message from the RNC for selecting at least one of the ANs;
- excluding an AN having the worst channel condition for the AT from the RNC;
- determining whether to transmit reverse power control information to the AT according to the received message;
- and
- transmitting the reverse power control (RPC) information to the AT if transmission of the reverse power control information is determined.
A method of controlling transmission of reverse power control information in an AN (Access Network) of a mobile communication system having an AT (Access Terminal), a plurality of ANs in an active set communicable with the AT during soft handoff, and an RNC (Radio Network Controller) connected to the plurality of ANs, comprising steps of:
- receiving information indicating at least one of the ANs excluding an AN having worst channel condition from the AT;
- determining whether to transmit reverse power control information to the AT according to the information received;
- and
- transmitting the reverse power control information to the AT if transmission of the reverse power control information is determined.
An apparatus for controlling transmission of reverse power control information in an AN (Access Network) of a mobile communication system having an AT (Access Terminal), a plurality of ANs in an active set communicable with the AT during soft handoff, and an RNC (Radio Network Controller) connected to the plurality of ANs, comprising:
- a receiver for receiving a message for selecting at least one of the ANs excluding an AN having the worst channel condition for the AT from the RNC;
- a controller for determining whether to transmit reverse power control information to the AT according to the received message;
- and
- a transmitter for transmitting the reverse power control information to the AT if transmission of the reverse power control information is determined.
