    摘要: A scheduler at a base station may schedule packet data traffic based on a ranking metric that varies directly with the mobile station's scheduling downlink transmission rate and a delay factor indicative of the staleness of the corresponding queued data. The ranking metric may advantageously vary in a direct non-linear fashion with the delay factor to allow for delay sensitive data, such as VoIP data, to be scheduled with increased urgency when quality of service is about to be compromised. The scheduler may attempt to pack a multi-user downlink physical layer packet by selecting a tentative rate and determining if an aggregate amount of data in the packet may be increased by transmitting the packet at a lower rate. If so, additional queued data is added to the packet and the transmission rate for the packet is lowered. Such an approach allows for greater link efficiency to be achieved.

    摘要: Carrier frequency selection is enabled in transmitting packet data between a radio transceiver and a mobile station and in a wireless communication network with shared packet data service. The packet data service permits transmission of packet data along a packet data link comprising a plurality of shared packet data channels, such as that provided by the N×EV-DO protocol. Each channel is characterized by a unique carrier frequency. Packet data may be divided and transmitted among the plurality of channels. Packet data may be transmitted along a first of the plurality of channels. Upon receiving a negative acknowledgement indicative of an erroneous packet transmission in accordance with known error control schemes such as HARQ, retransmission data may be transmitted along a second of the plurality of channels. As multiple carrier frequencies are used to transmit packet data and retransmission data, frequency diversity is added to time diversity inherent in retransmission protocols.

    摘要: A method of managing macro network coverage among a plurality of repeaters deployed to extend coverage of one or more base stations may include receiving feedback information from at least two repeaters indicative of macro network coverage at locations corresponding to each repeater, determining a coverage status of the macro network based on the feedback information, and sending a control signal to at least one repeater instructing the repeater to adjust one or more operating parameters based on the determined coverage status.

    摘要: Techniques for supporting handoff of terminals between a packet-switched network and a circuit-switched network are described. In an aspect, handoff between packet-switched and circuit-switched networks may be facilitated by a designated network entity in the packet-switched network. The designated network entity may interface with both the packet-switched network and the circuit-switched network, perform circuit-switched call origination, and perform handoff procedure. In one design, a first terminal may communicate with the packet-switched network for a packet-switched call with a second terminal. The first terminal may initiate handoff to the circuit-switched network via the designated network entity. The first terminal may perform handoff from the packet-switched network to the circuit-switched network based on an inter-MSC handoff procedure. The first terminal may then communicate with the circuit-switched network for the circuit-switched call with the second terminal after the handoff.
