    • A variable length sequence number is used to identify data units in a communication channel. The sequence number associated with the most recent data that has been received successfully and the sequence number expected with the next new data message to be received are examined to determine the minimum size sequence number necessary to unambiguously identify to the transmitter incorrectly received data that must be retransmitted in a later message. The receiver provides the transmitter with the sequence number associated with the last successfully received byte of data and the sequence number associated with the next expected byte of data. The receiver communicates this information to the transmitter using a NAK control message. The transmitter then uses the sequence number of the next byte of data to be transmitted and the information received in the control message from the receiver to determine the smallest number of bits necessary to represent the sequence numbers for both data transmissions and the retransmission of data that was not received properly by the receiver.
    • 可变长度序列号用于识别通信信道中的数据单元。 检查与已经成功接收的最新数据相关联的序列号以及预期接收到的下一个新数据消息的序列号,以确定明确识别发射机所必需的最小大小序列号,这些数据必须是 在稍后的消息中重传。 接收器向发射机提供与最后成功接收的数据字节相关联的序列号以及与下一个预期数据字节相关联的序列号。 接收机使用NAK控制消息将该信息传送给发射机。 然后,发射机使用要发送的数据的下一字节的序列号和来自接收机的控制消息中接收的信息来确定表示数据传输的序列号所需的最小比特数,并且重传数据的数据, 接收机没有正确接收到。

    • A method for switching cells by a mobile equipment of a communication system. The mobile transmits a signal coded with a spreading code indicating the mobile's intent to switch cells and the coded information also identifies to which cell the mobile wants to switch. The coded information contains channel measurement adjustment information that is continuously transmitted to the cell which is currently serving the mobile. The flow of channel measurement adjustment information is therefore not disturbed by the application of the method of the present invention. Because the coded information identifies the target cell and indicates the mobile's intent to perform a cell switching procedure, the amount of processing done by the cells is significantly reduced thus increasing the likelihood of a successful switching procedure.
    • 一种通过通信系统的移动设备切换小区的方法。 移动台发送用指示移动台切换小区的意图的扩展码编码的信号,并且编码信息还标识移动台想要切换到哪个小区。 编码信息包含连续发送到当前正在为移动台服务的小区的信道测量调整信息。 因此,通过应用本发明的方法,不会妨碍信道测量调整信息的流动。 由于编码信息识别目标小区并且指示移动台执行小区切换过程的意图,所以小区完成的处理量显着减少,从而增加成功切换过程的可能性。

    • A method for performing network control in wireless communication systems and a network entity for performing the same. The method and network entity pool at least one network parameter at the network entity, from at least two active set base transceiver stations and determine a current status of a mobile in the wireless communication system, using the pooled network parameters. The active set base transceiver stations may include a serving base transceiver station and a target base transceiver station. The network parameter may be a confidence metric and/or an error metric for each of a plurality of hypotheses, a power up/power down signal, and/or a measured signal-to-noise ratio and/or energy parameter of a pilot signal from the mobile. The current status of the mobile to be determined may be the mobile's decision to switch to the target base transceiver station transceiver or which base transceiver station transceiver the mobile is currently communication with. The network entity may be a base station controller or a base transceiver station in the active set of base transceiver station transceivers for the mobile in question.
