    • A subscriber (1001) provides a cumulative adjustment value in memory. Upon transmission of the inbound signal to a base station (102), the subscriber (1001) receives a relative adjustment value. The base station (102) calculates the relative adjustment value based on receipt of the inbound signal against a time window. The subscriber (1001) sums the adjustment value with the cumulative adjustment value to create a new cumulative adjustment value. The subscriber (1001) stores the new cumulative adjustment value in memory, and a subsequent inbound signal is transmitted using the new cumulative adjustment value. Alternatively, the subscriber (1001) obtains a priori information as to when a base station (102) transmits a burst. Upon receipt of the burst, the subscriber (1001) calculates a time delay between when the burst was transmitted and when the burst was received. The subscriber (1001) stores the time delay, and advances the transmission timing by the time delay.
    • 订户(1001)在存储器中提供累积调整值。 在将入站信号发送到基站(102)时,订户(1001)接收相对调整值。 基站(102)基于对时间窗口的入站信号的接收来计算相对调整值。 订户(1001)将调整值与累积调整值相加以创建新的累积调整值。 订户(1001)将新的累积调整值存储在存储器中,并且使用新的累积调整值发送后续的入站信号。 或者,订户(1001)获得关于基站(102)何时发送突发的先验信息。 在接收到突发之后,用户(1001)计算在发送突发和接收到突发之间的时间延迟。 用户(1001)存储时间延迟,并且将发送定时提前时间延迟。

    • An outbound message (200) identifies a slot type associated with each timeslot in a scheduling period. In one embodiment, the outbound message further identifies at least an address of a first subscriber group assigned to transmit in a first timeslot (206) if the slot type of the first timeslot is of a first type and an address of a second subscriber group assigned to transmit in a second timeslot (208) if the slot type of the second timeslot is of a second type, wherein the first type and the second type could be the same or different. In a second embodiment, the outbound message further identifies at least a group address associated with a plurality of subscriber units assigned to transmit in a first timeslot if the slot type of the first timeslot is of a first type. In yet a third embodiment, the outbound message further identifies an address of a first subscriber group assigned to transmit in a first timeslot if the slot type of the first timeslot is of the first type, and a second timeslot (210) of a second type.
    • 出站消息(200)标识与调度周期中的每个时隙关联的时隙类型。 在一个实施例中,如果第一时隙的时隙类型是第一类型并且第二用户组的地址是第一时隙(206),则出站消息还标识至少被分配用于在第一时隙(206)中传输的第一用户组的地址 如果第二时隙的时隙类型是第二类型,则在第二时隙(208)中传输,其中第一类型和第二类型可以相同或不同。 在第二实施例中,如果第一时隙的时隙类型是第一类型,则出站消息进一步标识与被指派为在第一时隙中传输的多个用户单元相关联的至少一个组地址。 在又一第三实施例中,如果第一时隙的时隙类型是第一类型,则出站消息还标识被分配用于在第一时隙中传输的第一用户组的地址,并且第二类型的第二时隙(210) 。

    • A radio frequency communications system (100) includes wireless terminals (102) communicating with base sites (104) over a radio frequency channel (106). The base sites are interconnected to each other and other network elements via a packet network. A radio frequency channel (400) includes time slots (406, 408) for transmission of delay-sensitive data, such as streaming audio and video, and non-delay-sensitive data. A method and apparatus are provided for determining whether a time slot in the radio frequency channel is to be allocated to delay-sensitive data or non-delay-sensitive data (704, 706, 708). Each packet of data transmitted over the wireless channel has a type of service field (900). The type of service field has a precedence or priority value (902) and a service type (904). The priority values are used to determine which packet should be transmitted across the radio frequency channel next and the service type determines the transmission protocol.
    • 射频通信系统(100)包括通过射频信道(106)与基站(104)通信的无线终端(102)。 基站经由分组网络彼此互连和其它网络元件。 射频信道(400)包括用于传输诸如流式音频和视频之类的延迟敏感数据和不延迟敏感数据的时隙(406,408)。 提供一种方法和装置,用于确定射频信道中的时隙是否被分配给延迟敏感数据或非延迟敏感数据(704,706,708)。 通过无线信道发送的每个数据分组具有一种服务字段(900)。 服务类型具有优先级或优先权值(902)和服务类型(904)。 优先级值用于确定哪个分组应在下一个射频信道上传输,业务类型决定传输协议。
