摘要： A transmission power control apparatus includes a transmission power control signal extracting section, transmission power control signal storage section, transmission power control determination section, and transmission power changing section. The transmission power control signal extracting section extracts a transmission power control signal from a reception signal containing a transmission power control signal. The transmission power control signal storage section sequentially stores transmission power control signals output from the transmission power control signal extracting section. The transmission power control determination section determines whether an instruction to increase/decrease transmission power based on a plurality of transmission power control signals stored in the transmission power control signal storage section is repeatedly generated. The transmission power changing section stops transmission power updating operation if the determination result from the transmission power control determination section indicates that the transmission power is repeatedly increased/decreased. A transmission power control method is also disclosed (Fig. 1).

摘要： In a telecommunication system (10) for providing multimedia broadcast services to many user equipments (40-45), a physical random access channel (39) is provided for uplink transmission of power control information from the user equipments to a radio site (30, 35). Based upon a comparison of signal-to-noise ratios (53) each particular user equipment sends (55) or inhibits from sending a power control signal to the radio site to which it is coupled. When the radio site of the telecommunication system detects a power control signal (73), the radio site adjusts the transmission power of a broadcast channel intended for reception by multiple user equipments (75) to be incrementally greater than the previous power (81). For lack of detection of a power control signal, adjusts the transmission power of a broadcast channel to be incrementally lower than the previous power.

摘要： A radio communication system comprises a primary station adapted to transmit a series of data packets on a downlink channel to a secondary station. The primary station determines a property relating to the Doppler spread of the downlink channel and uses this property in the determination of suitable parameters for packet transmission. Possible properties from which an indication of the Doppler spread can be derived include the received signal to interference ratio and the transmitted power control commands. Possible parameters for packet transmission include transmission power, modulation and coding scheme, delay before retransmission of a packet received in error, and spreading factor. By determining packet transmission parameters based on uplink signal properties or on transmitted power control commands, the need for the secondary station to measure radio channel properties and signal these to the primary station is removed, thereby reducing signalling traffic and overall interference levels and extending battery life.

摘要： To determine a level of loading, the system enters a period of silence during which a designated remote unit continues to transmit but other transmissions are interrupted. The base station and designated remote unit perform closed loop power control on a reverse link signal. A first series of power control commands and a first corresponding transmit gain adjustment value is stored. Normal operation is resumed. A second series of commands and a second corresponding transmit gain adjustment value is stored. A level of loading is determined based upon the first and second transmit gain adjustment values. In another embodiment in the period of silence all the remote stations cease transmission, and the base station measures a power of RF test signal injected into base station receiver. In yet another embodiment in the period of silence all the remote stations cease transmission. And the base station measures a value reflecting gain of an AGC circuit of the base station's receiver. Second measured values.

摘要： A method and apparatus for dynamically adjusting the signal-to-interference ratio (SIR) threshold used to control signal transmission power in closed loop communication systems. The closed loop power control comprises an inner loop that provides up/down transmission power control commands to a transmitter based upon a comparison of the SIR for a received signal to the threshold SIR. The outer loop dynamically adjusts the threshold SIR using historic inner loop power control information. When it is detected that the inner loop is not acceptably performing power control, the target SIR is not changed, or may be increased or decreased more or less than 0.5 dB or 0.5 dB/99, respectively.
