Abstract: A base station receives multiple first signals from multiple mobile terminals over a first radio channel (e.g., a RACH, a CPCH, etc.). Multiple acknowledgement signals are generated for transmission over an acquisition indication channel (AICH) during a same access time slot. Each acknowledgement signal is responsive to one of the mobile terminals and includes a signature sequence of bits associated with the first signal received from that mobile terminal. An AICH transmission power profile is determined for the access time slot. If the AICH transmission power profile exceeds a predetermined maximum transmission power parameter, then a first portion of the an AICH transmission power profile is adjusted. Thereafter, the acknowledgement signals are transmitted over the AICH in accordance with the adjusted AICH transmission power profile.

Abstract: The transmit power of a radio transmitter associated with a transmitting node communicating with a receiving node is controlled based on a propagation delay time associated with communication between the transmitting node and the receiving node. A power control loop is established for controlling a transmission power level for transmitting a signal from the transmitting node to the receiving node. A response time of the power control loop is reduced based on the propagation delay time.

Abstract: An inherent non-observability of the thermal noise power level is circumvented by estimating an upper limit of the thermal noise power level by time evaluations. An instantaneous total received wideband power is measured in a receiver. Preferably, also an instantaneous sum of powers of all links used in the same cell is provided. A quantity (P′), preferably the difference between the instantaneous total received wideband power and the instantaneous sum of powers of all links used in the same cell, is followed (110) during a time period (TLag). A minimum value (PMIN) of that quantity is then used as an estimate of the thermal noise power level upper limit. Preferably, the time period is configured as a sliding window. An improved determination of noise rise can then be calculated and used for controlling traffic within the cell.
