摘要： A scheduler (60) at a base station (36) 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： A wireless communication network has radio resources for use to support calls over circuit switched (CS) and packet switched (PS) channels. The network uses such radio resources to first support CS calls and thereafter uses the leftover radio resources to support PS calls. The present invention provides method and apparatus that effectively schedule and support incoming CS calls based on frame-offset selection so as to maximize the leftover radio resources that could be used to support PS calls.

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 NxEV-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.
摘要翻译：在无线电收发器和移动台之间以及在具有共享分组数据服务的无线通信网络中传送分组数据时启用载波频率选择。分组数据服务允许沿着包括由NxEV-DO协议提供的多个共享分组数据信道的分组数据链路传输分组数据。每个通道的特征在于唯一的载波频率。分组数据可以在多个信道之间分割和发送。分组数据可以沿多个信道中的第一个发送。在根据诸如HARQ的已知错误控制方案接收到指示错误分组传输的否定确认时，重传数据可以沿多个信道中的第二个发送。由于多个载波频率用于发送分组数据和重传数据，所以频率分集被添加到重传协议固有的时间分集中。

摘要： Techniques for sending and receiving signaling messages on shared and dedicated channels in a wireless communication system are described. A user equipment (UE) may receive a first signaling message on a shared channel during a first time period, receive a second signaling message on a dedicated channel during a second time period, and receive a third signaling message on the shared channel during a third time period. The UE may receive traffic data on the shared channel during all time periods. The UE may be handed over from a source Node B to a target Node B during the second time period. The UE may receive the first signaling message via the source Node B, receive the second signaling message via the source and target Node Bs, and receive the third signaling message via the target Node B.

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.

摘要： In a Time-Division Duplex (TDD) data frame, wherein time slots are allocated to downlink and uplink transmissions, time slots are allocated to pending communication signals beginning at the start of the data frame for one of downlink and uplink transmissions, and are allocated to pending communication signals beginning at the end of the frame for the other of downlink and uplink transmissions. When one or more time slots allocated to downlink and/or uplink transmissions are not utilized for actual communication signal transmission, the non-utilized time slot(s) occur towards the middle of the TDD data frame rather than at the end. This reduces the probability of base station/subscriber terminal interference with another sector or cell utilizing a different downlink/uplink time slot allocation.
摘要翻译：在其中时隙被分配给下行链路和上行链路传输的时分双工（TDD）数据帧中，时隙被分配给在数据帧的开始处开始的未决通信信号，以用于下行链路和上行链路传输，并且被分配给用于下行链路和上行链路传输中的另一个传输的帧的结尾处开始的未决通信信号。当分配给下行链路和/或上行链路传输的一个或多个时隙不用于实际的通信信号传输时，未使用的时隙发生在TDD数据帧的中间而不是末端。这降低了基站/用户终端利用不同的下行链路/上行链路时隙分配与另一扇区或小区干扰的概率。
