Mobile station and weighting control method
First Claim
1. A method of controlling weighting of a mobile station in a communication system for transmitting the same data from a plurality of base stations to a mobile station on a first channel and transmitting other data from one base station to the mobile station intermittently on a second channel during communication on the first channel, said method comprising:
- in a first state in which the same data is being received from the plurality of base stations on the first channel and data is not being received on the second channel, a step of deciding weight in such a manner that first weighting is applied to signals received from respective ones of the base stations and performing prescribed control based upon the signals to which the first weighting has been applied;
in a second state in which the same data is being received from the plurality of base stations on the first channel and data is being received from one base station on the second channel, a step of deciding a weight in such a manner that second weighting is applied to signals received from respective ones of the base stations and performing the prescribed control based upon the signals to which the second weighting has been applied; and
an adaptive control step of adaptively controlling timing of transition from the second weighting to the first weighting when the second state has changed to the first state.

Abstract
In a first state in which the same voice data is being received from a plurality of base stations on a first channel (DPCH) and a packet is not being received on a second channel (HS-PDSCH), weight is decided in such a manner that first weighting is applied to signals received from respective ones of the base stations and prescribed control is performed based upon the signals to which the first weighting has been applied. In a second state in which the same voice data is being received from a plurality of base stations on the first channel and a packet is not being received on the second channel, weight is decided in such a manner that second weighting is applied to signals received from respective ones of the base stations and prescribed control is performed based upon the signals to which the second weighting has been applied. When the second state has changed to the first state, transition time (protection time) TMR at which there is a transition from second weighting to first weighting is controlled adaptively.

9. A mobile station in a communication system for transmitting the same data from a plurality of base stations to a mobile station on a first channel and transmitting other data from one base station to the mobile station intermittently on a second channel during communication on the first channel, said mobile station comprising:
-
a first receiver for receiving the same data from the plurality of base stations on the first channel;
a second receiver for receiving other data from one base station intermittently on a second channel;
a weight calculation unit which, in a first state in which the same data is being received from the plurality of base stations on the first channel and data is not being received from any base station on the second channel, is for deciding weight in such a manner that first weighting is applied to signals received from respective ones of the base stations, and in a second state in which the same data is being received from the plurality of base stations on the first channel and data is being received from one base station on the second channel, is for deciding a weight in such a manner that second weighting is applied to signals received from respective ones of the base stations;
a transition timing decision unit for deciding a timing at which there is a transition from the second weighting to the first weighting when the second state has changed to the first state; and
a controller for performing prescribed control based upon the weighted signals. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A mobile station for receiving data of the same content from both a first base station, which transmits data of the same content by antenna diversity using first and second antennas, and a second base station, which transmits data of the same content by antenna diversity using third and fourth antennas, comprising:
a weighting phase controller for changing a length of time over which phase control relating to the first and second antennas of the first base station is performed at a priority higher than that of phase control relating to the third and fourth antennas of the second base station in accordance with a reception interval of HS-PDSCH transmitted using the first and second antennas. - View Dependent Claims (18)

19. A mobile station for receiving data of the same content from both a first base station, which transmits data of the same content by antenna diversity using first and second antennas, and a second base station, which transmits data of the same content by antenna diversity using third and fourth antennas, said mobile station having:
-
a receiver which, in a case where the first base station is a base station that transmits HS-PDSCH to the mobile station using the first and second antennas, is for receiving a command signal from said first base station, said command signal being a signal for giving phase control relating to the first and second antennas of the first base station a higher priority than phase control relating to the third and fourth antennas of the second base station; and
a transmitter for transmitting a signal for phase control in accordance with the command signal to the first and second base stations. - View Dependent Claims (20)
