Mobile station and transmission diversity weighting control method

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 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.

Description

technical field [0001] The present invention relates to a mobile station and a weight control method. More specifically, the present invention relates to a method for transmitting the same data from a plurality of base stations to a mobile station on a first channel, and during communication on the first channel, intermittently from a base station to a mobile station on a second channel. A mobile station in a communication system in which the mobile station transmits other data, and a method for controlling the weighting of the mobile station. Background technique [0002] ·Closed-loop transmit diversity system [0003] In a closed-loop transmit diversity system, a mobile phone communication system has multiple antenna elements. The system (1) performs different amplitude and phase control on a plurality of identical transmitted data signals according to the feedback information transmitted from the mobile station, (2) controls the pilot signal with the amplitude and phase...

AI Technical Summary

Problems solved by technology

As a result, at the beginning of the time slot SL3' where the base station transmits packets, the transmitter cannot adopt weights consistent with the FBI when α = 1.0, and cannot reflect the performance of the fast handover operation itself

Therefore, in the case where data (packets) transmitted to the mobile station itself are transmitted in bursts, that is, when data is transmitted intermittently by the schedule of the base station, a problem occurs that cannot effectively reflect the performance of the fast handover operation itself. question
