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:
The present invention relates to a mobile wireless communication system including a base station and a mobile station, and has an object to obtain a communication system capable of reducing power cons To attain the above object, a base station (1) transmits control information on the number of to-be-received HS-SCCHs to a mobile station (2) through an HS-PDSCH without making the control information go through a process by an RRC layer process block (901). The mobile station (2) changes settings on the number of to-be-received HS-SCCHs based on the control information on the number of to-be-received HS-SCCHs received from the base station (1) without making the control information go through a process by an RRC layer process block (101).

A communication system capable of changing transmission format of data to change transmission rate according to quality information of the downlink. The probability of transmission collision causing interference is reduced by setting the values of transmission periods of mobile stations to prime numbers which are not multiples of one another.

A mobile station includes an amount-of-data information determining means for monitoring data which are stored on a communication-service-by-communication-service basis or on a transmit-channel-by-transmit-channel so as to determine communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information. The mobile station transmits the communication-service-by-communication-service or transmit-channel-by-transmit-channel amount-of-data information determined by the amount-of-data information determining means to a base station.
摘要:
A communications system is provided with a mobile station and a base station, the mobile station including a radio link control unit for outputting or inputting data which are transmitted or received via a radio channel to or from a higher-level protocol layer, a media access control unit for outputting or inputting the data via a logical channel to or from the radio link control unit, a physical layer control unit for outputting or inputting the data via a transport channel to or from the media access control unit, and for controlling radio communications, and a radio resource control unit for outputting or inputting control data to or from the radio link control unit, media access control unit, and physical layer control unit. The mobile station multiplexes report information therefrom into a channel for packet data transmission so as to transmit the report information to the base station, and the base station carries out assignment of radio resources using the report information which it receives from the mobile station.

A portable radio determines (S1, S2) an upper limit (STEPLIM) of transmission power corresponding to the temperature (T), makes a decision (S3, S4) whether the set value (STEPn) of transmission power in the next slot exceeds the upper limit (STEPLIM) or not, provides (S5, S7) a control signal value (Vc) corresponding to the set value (STEPn) of transmission power to variable gain blocks (11, 13) if the upper limit (STEPLIM) is not exceeded, otherwise provides (S6, S7) a control signal value (Vc) corresponding to the upper limit (STEPLIM) of transmission power to the variable gain blocks (11, 13).
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.

A scrambling unit (54) IQ-multiplexes the output signal of a spectrum-spreader (52) and the output signal of a distributor (53) to generate a complex signal (I signal, Q signal). In this generation, the amplitude factors (βcc(I), βcc(Q)) for ADPCC are determined while the signal power of the I-axis and the signal power of the Q-axis are taken into consideration.
