    摘要: A dynamic carrier selection method and system permit units operating on a first carrier to change to a second carrier when performance of the first carrier becomes unacceptable. Carrier quality measurements are taken in which carrier quality is a function of interference and multi-path fading and carrier-signal strength. The carriers are ranked according to measured quality in a carrier candidate list. The carrier candidate list is used to permit units to determine which carrier they should switch to when the carrier there currently operating on is determined to have unacceptable performance. Carrier measurements are retaken in response to a carrier change by unit or a predetermined time period having elapsed.

    摘要: Wireless communication terminals and methods are disclosed that determine acoustic ranging synchronized to RF communication signals. A communication terminal can include a RF transceiver, a microphone, and a controller. The controller synchronizes a clock in response to known timing characteristics of received RF communication signals. The controller determines an acoustic signal generation time relative to the RF communication signal synchronized clock at which the other communication terminal will generate an acoustic signal. The controller determines an acoustic signal receipt time relative to the RF signal synchronized clock when the acoustic signal from the other communication terminal is detected in the microphone signal. The controller further determines a propagation time of the acoustic signal from the other communication terminal to the microphone based on a difference between the acoustic signal generation time and the acoustic signal receipt time, and determines a range to the other communication terminal in response to the propagation time of the acoustic signal.

    摘要: Packet transmissions between a base station and terminals are performed using half-duplex uplink and downlink transmission intervals with adaptive intra-interval packet retransmission and packet expansion. The uplink and downlink transmission intervals used for communication with a terminal may be offset commensurate with a degree of symmetry of information flow between the terminal and the base station. The offset between the uplink and downlink transmission intervals may be adaptively adjusted based on a type of information being communicated between terminals and the base station. For example, different offsets may be used for voice and data communications. In some embodiments of the present invention, uplink and downlink transmission intervals for communications with a terminal have substantially equal durations. For example, voice packet transmissions between the base station and the terminal may use uplink and downlink transmission intervals having substantially equal durations.

    摘要: Transmitter and receiver functionality are separated in dual-mode radio transceivers to support high-rate services. Transceivers with highly asymmetric requirements that need only a high-rate transmission or only high-rate reception functionality are supported by including a high-rate transmitter to support pushing data out or a high-rate receiver to support pulling data into the transceiver at high data rates.
