Abstract: A method and apparatus improve the design and control of amplification stages in a radio frequency (RF) transmitter, so as to reduce its power consumption. In some aspects, the transmitter is operable to transmit an output RF signal at a target power level, which may vary over a wide dynamic range. For each target power level in the dynamic range, a control module in the transmitter configures operational settings of amplification stages of the transmitter in order to produce the output RF signal having the appropriate target power level, while consuming minimal power from the power source.

Abstract: Techniques to determine the position of a terminal under the coverage of a repeater in a wireless communication system. In an aspect, an identification code is transmitted for each repeater and used by the terminal (or a PDE) to unambiguously identify the repeater. The identification codes for the repeaters in the system can be implemented with PN sequences at defined offsets that are specifically reserved for repeater identification. In another aspect, the identification code for each repeater is transmitted using a spread-spectrum signal designed to have minimal impact on the performance of the system and to be recoverable by the terminal in similar manner as for a forward modulated signal. In this way, no additional hardware is required for the terminal to recover the identifier signal. In one specific design, the spread spectrum identifier signal is generated in accordance with and conforms to the IS-95 CDMA standard.

Abstract: A method for adjusting a power level in a communications network which includes a first plurality of signal-transmission-elements adapted to receive signals coupled to a second plurality of signal-transmission-elements adapted to transmit the signals, the method including de-activating at least some of the first plurality so that the signals are not received in the first plurality and de-activating at least some of the second plurality so that the signals are not transmitted from the second plurality. The method includes injecting a reference signal having a predetermined injected power level at the first plurality, receiving the reference signal at the second plurality, measuring a received power level of the reference signal at the second plurality, comparing the injected and received power levels, and, responsive to the comparison, setting a gain of at least one of the signal-transmission-elements comprised in the first and second pluralities.
