Abstract: PROBLEM TO BE SOLVED: To avoid leakage into the Rx chain of Tx signals.SOLUTION: A duplex radio transceiver 50, coupled to baseband circuitry and to an antenna 32, includes a receive chain 48, a transmit chain 46, and a duplexer 49. The transmit chain includes filter components 52 and 56 that attenuate signals originating from the transmit chain in a receive frequency band by a stop-band attenuation that is approximately equal to or greater than the stop-band attenuation of the duplexer in the receive frequency band. Similarly, the receive chain includes filter components 68 and 72 that attenuate signals in a transmit frequency band by a stop-band attenuation that is approximately equal to or greater than the stop-band attenuation of the duplexer in the transmit frequency band. A bias control circuit 74 senses a power level associated with radio signals in the transmit chain and adjusts an amplifier 66 in the receive chain responsive to the power level.

Abstract: A method for estimating a size of reverse link resources provided by a base-station transceiver system (BTS), including performing respective first, second, and third measurements of first, second, and third signal strengths received at the BTS. The method also includes comparing the first measurement with the second measurement so as to determine an initial minimum signal strength, and adding at a predetermined time an aging value to the initial minimum signal strength so as to form an updated minimum signal strength. The method further includes forming a comparison between the updated minimum signal strength and the third measurement, determining from the comparison a minimum of the updated minimum signal strength and the third measurement to be a minimum received signal strength, and determining the size of the reverse link resources provided by the BTS in response to the minimum received signal strength.

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.

Similarly, the receive chain (48) includes filter components (68,72) that attenuate signals in a transmit frequency band by a stop-band attenuation that is approximately equal to or greater than the stop-band attenuation of the duplexer in the transmit band. A bias control circuit (74) senses a power level associated with radio signals in the transmit chain and adjusts an amplifier (66) in the receive chain responsive to the power level.

Abstract: A method for communicating between a mobile transceiver in a multistory building and a wireless communication network external to the building, the building including alternating even and odd floors and having a near side and a far side, the method including dividing a plurality of slave transceivers into a main sub-group of slave transceivers and a diversity sub-group of slave transceivers, the transceivers being operative to transmit signals of a type which are conveyed over the wireless communication network. The method further includes positioning at the near side of at least one of the even floors one of the slave transceivers from the main sub-group and positioning at the far side of the at least one of the even floors one of the slave transceivers from the diversity sub-group, and also positioning at the near side of at least one of the odd floors another one of the slave transceivers from the diversity sub-group and positioning at the far side of the at least one of the odd floors another one of the slave transceivers from the main sub-group. The method further includes conveying a signal between the wireless communication network and the mobile transceiver via one or more of the plurality of slave transceivers positioned in the building.
