摘要： A base station of the cellular telephone forward link power control system transmits frames initially at a high default transmit power level, then decreases the power level incrementally until either a frame erasure is detected, triggering an immediate sharp increase in transmission power, or until a predetermined period of time has elapsed, after which the base station performs a fast downward move in the transmit power level. The fast downward move constitutes a sharp reduction in the transmit power level. In one example, the fast downward move is performed if one hundred consecutive frames are successfully transmitted without a frame erasure. By providing the fast downward move in transmit power, the power transmitted is decreased on the average. In particular, the fast downward move allows the amount of transmit power to be reduced significantly in circumstances where slow incremental decreases in power would result in excess power being employed. Method and apparatus embodiments are disclosed.

摘要： PROBLEM TO BE SOLVED: To provide a reverse link channel structure in which data transmission characteristic in a reverse link has been taken into consideration. SOLUTION: Mechanisms are provided to quickly assign resources (e.g., a supplemental channel) as needed, and to quickly de-assign the resources when not needed or to maintain system stability. The reverse link resources may be quickly assigned or de-assigned by short messages exchanged on control channels on forward and reverse links. A reliable acknowledgment/negative acknowledgment scheme and an efficient retransmission scheme are provided. Mechanisms are also provided to control a transmission power and/or data rate of a remote terminal to achieve high performance and avoid instability. COPYRIGHT: (C)2008,JPO&INPIT

摘要： Techniques for power control of serving and non-serving base stations are disclosed. In one aspect, power control commands for a plurality of base stations are combined to form a single command to control the plurality of base control. In another aspect, an "Or-of-up" rule is used to combine the power control commands. In yet another aspect, a channel quality indicator is used to power control a serving base station. Various other aspects are also presented. These aspects have the benefit of providing efficient power control between a mobile station and both serving and non-serving base stations, thus avoiding excessive interference and increasing capacity.

摘要： PROBLEM TO BE SOLVED: To effectively utilize few frequencies and to increase capacity by applying an interference elimination technique of separating respective reception signals of SIC (Successive Interference Canceller) or the like. SOLUTION: At the time of transmitting signals on the channel of the same space, time, and frequency, each radio transmitter autonomously changes transmission power according to a predetermined hopping pattern. A radio receiver is mounted with the SIC and detects desired signals and interference signals. Since power hopping is performed by respectively different hopping patterns for the transmission output of the respective signals, a desired relation is satisfied between the reception power of the respective signals and thus the signals are separated.

摘要： PROBLEM TO BE SOLVED: To attain high quality of communication, to reduce transmission power and to increase the communication capacity by controlling transmission power on the basis of a synthesis reception signal power/interference signal power ratio of at least two channels used for transmission and a predetermined object reception signal power/interference signal power ratio. SOLUTION: An SIR synthesis section 8 outputs a reception SIR that is an SIR obtained by combining reception signal power (S) of channels in a transmission ON state to an object SIR comparison section 10 on the basis of reception signal power (S) and interference power (I) for each channel (control channel + a plurality of communication channels) received from an SIR measurement section 6 and a transmission ON/OFF state of each channel received from a transmission ON/OFF discrimination section 7. In the case of reception SIR object SIR, the section 11 decides a control bit indicating decrease in the transmission power.
