摘要:
A mobile communications terminal divides a plurality of multipath signals associated with radio signals transmitted from a plurality of base stations 5 using an S-CCPCH into groups by base station, i.e., by transmit source, maximum-ratio-combines a plurality of multipath signals associated with each same base station 5 which is a transmit source into a composite signal, decodes the composite signal, and selects a composite signal having a good decoded result from among decoded composite signals.

In order to carry out high-speed packet communications using a large-volume transmission channel like an E-DCH, uplink communication quality must be good. However, in a state in which a link imbalance occurs, a mobile station cannot estimate the uplink communication quality from downlink communication quality. Therefore, the mobile station calculates a path loss from the setting power of a common pilot channel which is notified from a base station, and the received power of the common pilot channel received thereby, and also estimates the received power in the base station on the basis of this path loss. The mobile station further judges the uplink communication quality by estimating the SIR in the base station by using the interference power notified from the base station and the estimated received power.

摘要:
A communication mode which should be set to a mobile communication terminal having a function of switching between an autonomous mode and a scheduling mode is determined based on an amount of interference in each of the communication modes in the cell of a base station, and/or communication characteristics of each of the communication modes, and a signal indicating an amount of communication data notified from the mobile communication terminal. The base station then notifies the determined communication mode to the mobile communication terminal.
