摘要:
There is a problem that no unique specific detailed regulation is existent with respect to mobile station status information to be notified by mobile stations to a fixed station, so that the operations of the mobile stations within a communication system may be different from one another and hence no efficient scheduling (wireless resource assignment) of the uplink can be achieved. A communication method includes a transmission process in which to multiplex a transport channel, on which data is transferred from an upper order layer, with a physical data channel and transmit the multiplexed channel to a fixed station; a status notification process in which to notify status information including information related to a transmission power margin to be used for a scheduling; and a transmission control process in which to receive a result of the scheduling to control the transmission process. In the status information notification process, indexes added to respective predetermined transmission power margin levels as divided between the upper and lower limits of the transmission power margin are notified of as the status information.
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.

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.

A base station control apparatus (3) sorts a plurality of base stations (2) into a base station of an E-DCH active set and a base station of an active set for soft handover (conventional active set), in accordance with data reception status at the base stations (2).
摘要:
According to a communications method according to the present invention, data is transmitted from a base station to two or more terminals via a common channel, and transmission power, with which the data is transmitted from the base station to the two or more terminals, is controlled according to a reception state of at least one of the two or more terminals. Furthermore, the terminal transmits reception capability information at a time of selection combining, and at least one of the two or more base stations receives the reception capability information at the time of selective combining and notifies the reception capability information to a radio network controller (RNC) which controls the two or more base stations. When a connection request is issued to the terminal, the RNC refuses assignment of a dedicated channel to the connection request when determining that the assignment of the dedicated channel to the terminal cannot be done based on the reception capability information at the time of selective combining.
