摘要： A multiple access, spread-spectrum communication system processes a plurality of information signals received by a Radio Carrier Station (RCS) over telecommunication lines for simultaneous transmission over a radio frequency (RF) channel as a code-division-multiplexed (CDM) signal to a group of Subscriber Units (SUs). The RCS receives a call request signal that corresponds to a telecommunication line information signal, and a user identification signal that identifies a user to receive the call. The RCS includes a plurality of Code Division Multiple Access (CDMA) modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a CDM processed signal. The RCS includes a system channel controller coupled to receive a remote call. An RF transmitter is connected to all of the modems to combine the CDM processed signals with the global pilot code signal to generate a CDM signal. The RF transmitter also modulates a carrier signal with the CDM signal and transmits the modulated carrier signal through an RF communication channel to the SUs. Each SU includes a CDMA modem which is also synchronized to the global pilot signal. The CDMA modem despreads the CDM signal and provides a despread information signal to the user. The system includes a closed loop power control system for maintaining a minimum system transmit power level for the RCS and the SUs, and system capacity management for maintaining a maximum number of active SUs for improved system performance.

摘要： PROBLEM TO BE SOLVED: To preferentially handle emergency communication or the like by a simple and effective method, when issuing the emergency communication or the like. SOLUTION: In the case of emergency in a mobile station 200, a special call 206 is changed to an emergency mode from a normal one, and a mobile station side communication section 206 transmits radio waves, where the power (power spectral density) of a transmission signal at a center frequency f 0 of a carrier wave is high. A base station 100 receives the radio waves, where the power (power spectral density) of the transmission signal is high at the center frequency f 0 of a carrier wave from the mobile station 200 that issues the emergency communication. The base station 100 transmits a suppression signal for suppressing signal strength to the other mobile station. Only the mobile station 200 issuing the emergency communication establishes a communication path with the base station 100. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a method, by which the output of an access packet (PA) transmitted from a mobile station (MS) can be controlled so that the input variations of the receiver of a transmitting-receiving base station is reduced.
SOLUTION: At a level of the transmitting-receiving base station (BTS), output information, indicating the transmission power (TPo(BTS)) of a broadcast channel (BCCH), is included on the broadcast channel. At the level of the mobile station (MS), the output received on this channel is measured; this measured output value (RP(MS)) is compared with the transmission power obtained from transmission power information contained in the broadcast channel(BCCH), to deduce the estimated propagation loss from the mobile station (MS) to the transmitting-receiving base station (BTS); and optimal transmission power for the access packet (PA) is determined, using the estimated propagation loss and parameters of a system. The method can be utilized for radiotelephony, particularly, a GSM system and a TETRA system.

摘要： PROBLEM TO BE SOLVED: To enhance a control method for initial power ramp-up during a communication channel setting period between a subscriber unit and a base station in a wireless CDMA communication system.
SOLUTION: A system and method of controlling transmission power during the establishment of a channel in the CDMA communication system utilize the transmission of a short code from the subscriber unit to the base station during initial power ramp-up. The short code is a sequence for detection by the base station which has a much shorter period than a conventional spreading code. The ramp-up starts from a power level that is guaranteed to be lower than the required power level for detection by the base station. The subscriber unit quickly increases transmission power while repeatedly transmitting the short code until the signal is detected by the base station. Once the base station detects the short code, it sends an indication to the subscriber unit to cease increasing transmission power. The use of short codes limits power overshoot and interference to other subscriber stations and permits the base station to quickly synchronize to the spreading code used by the subscriber unit.

摘要： PROBLEM TO BE SOLVED: To control transmission power in a cellular radio system by a little signal quantity taking the special necessity of a packet-switching link into consideration. SOLUTION: A terminal apparatus measures (30, 31) a control signal from a base station before the establishment of connection and during a long rest between packets and compares its signal power (R0) with an objective level which the base station holds. The base station notifies the transmission power by the control signal, too, and the terminal apparatus regards the same power as the transmission power by correcting only a difference (t0-R0) between the objective level and quality for a link to be measured (32). The quality (RXQUAL) for the link to be measured is transmitted as an acknowledgement message and the transmission power is changed so as that the quality reaches a definite objective level at a transmission side. The maximum width of the change is decided by the length of the packet. The base station uses the maximum power at first in packet transfer to a down link direction and then corrects the transmission power based on measured information in an acknowledgement message transmitted from the terminal apparatus.

摘要： PROBLEM TO BE SOLVED: To provide a service providing apparatus or the like capable of making communication with a desired communication opposite party while securing the security. SOLUTION: A near distance communication system is provided with a cash register 1 and Bluetooth(R) mobile terminals 2, which make near distance communication with each other. While the cash register 1 applies a searching request processing and a connection request processing to a Bluetooth(R) mobile terminal 2, the cash register 1 reduces the transmission power to be connected only to a desired Bluetooth(R) mobile terminal 2, and the cash register 1 increases the transmission power when the cash register 1 provides a service. Thus, the cash register 1 can surely be connected to the desired Bluetooth(R) mobile terminal 2, and after the cash register 1 has been once connected to the Bluetooth(R) mobile terminal 2, the cash register 1 can provide the service to the Bluetooth(R) mobile terminal 2 even when the Bluetooth(R) mobile terminal 2 moves over a comparatively wide range.

摘要： When performing base station selection type transmission power control, transmission of the dedicated physical control channel signal by non-transmitting base stations is halted while minimizing the impact on uplink transmission power control. This decreases downlink interference and increases downlink channel capacity. At a base station, reception quality measuring unit 506 compares the measured uplink reception quality with a target quality, forms a TPC signal on the basis of the results of this comparison, and communicates the contents of this TPC signal to transmission power controller 507. When the base station in question is a non-transmitting base station, transmission power controller 507 transmits the dedicated physical control channel signal only if the contents of the communicated TPC signal instruct a decrease, and otherwise halts transmission of the dedicated physical control channel signal.
