摘要： The invention relates to methods for establishing a radio bearer between a network element terminating radio resource control protocol and a mobile terminal. The invention provides RNC for establishing a radio bearer between the RNC and a mobile terminal, especially adapted mobile terminals and a system comprising the network element and at least one mobile terminal. In order to reduce the delays implied by the signaling in the procedure the invention proposes two mechanisms. The first mechanism aims at reducing the delay implied by setting up the radio link for the radio bearer by preconfiguring a pool of resources comprising a set of at least radio bearer configuration and making the available radio bearer configurations known to the mobile terminals. The second mechanism aims at avoiding the delay implied by the explicit assignment of a radio network temporary identifier by signaling a set of available identifiers from which the mobile terminal may choose an identifier.

摘要： An allocation section 101 in a base station apparatus of the present invention sets the transmission rate of a transmit signal for a communication terminal apparatus based on a DRC signal transmitted from that communication terminal apparatus. A power margin information detector 117 detects power margin information from a demodulated signal generated by a demodulator 115, and, using that power margin information, a power setting section 118 makes a setting so as to give the minimum transmission power value at which received signal characteristics in each communication terminal apparatus meet the desired quality. Using the set transmission power value, the base station apparatus transmits a transmit signal of the set transmission rate to a communication terminal apparatus. By this means it is possible to suppress interference to a communication terminal apparatus that performs adaptive modulation communication with another base station apparatus and a communication terminal apparatus that performs adaptive modulation communication with the local base station apparatus at the same time.

摘要： Priority determining section 107 determines priority of each communication terminal apparatus based on the information indicating the channel quality of the downlink. Transmission destination determining section 108 estimates the direction in which each communication terminal apparatus exists from the information indicating the direction of arrival of the signal and determines the communication terminal apparatuses to which downlink high-speed packet transmission is performed based on the direction in which each communication terminal apparatus exists and priority. AAA transmission control section 154 calculates a transmission weight based on the direction of arrival of the signal sent from the communication terminal apparatus determined by transmission destination determining section 108. Then, AAA transmission control section 154 multiplies the signals sent from antenna elements 101 to 103 by transmission weights. When adaptive array is used, this makes it possible to carry out effective downlink high-speed packet transmission.

摘要： A mobile communication system which is capable of, when carrying out mobile communication using a shared channel, increasing in efficiency of transmission timing of the data transmission rate request value to prevent wasteful power consumption and hence reduce power consumption. The mobile station apparatus 102 of the mobile communication system measures CIR of the received signal from the base station apparatus 101 at the CIR measuring section 306, and decides the data transmission rate request value corresponding to the measured CIR value at the rate request value deciding section 307. Also, it detects an error of the received signal at the CRC section 304, and, when no error is found, calculates a difference between the average data transmission rate from the base station apparatus 101 and the data transmission request value at the rate request value transmission controlling section 308. Then, it transmits the data transmission rate request value to the base station apparatus 101 only when the obtained difference is larger than a threshold value.

摘要： The invention relates methods for time aligning uplink transmissions by a mobile terminal in a mobile communication system, and to methods for performing a handover of a mobile terminal to a target aggregation access point. The invention is also providing apparatus and system for performing these methods, and computer readable media the instructions of which cause the apparatus and system to perform the methods described herein. In order to allow for aligning the timing of uplink transmissions on uplink component carriers, where different propagation delays are imposed on the transmissions on the uplink component carriers, the inventions suggests to time align the uplink component carriers based on a reference time alignment of a reference cell and a reception time difference or propagation delay difference between the downlink transmissions in the reference cell and the other radio cells, the uplink component carriers of which need to be time aligned.
