    • It is an object of the present invention to actualize a packet scheduling method and a device thereof that improve a throughput of packet data transmitted and received in a way that suppresses deterioration in communication quality due to interference between packet data signals. The packet scheduling method includes a step of receiving each of wireless signals transmitted from a plurality of terminals, a determination step of determining a combination of the terminals having an interference-suppressed relationship and the terminals having a mutually-interfered relationship among the plurality of terminals based on the respective signals received, and a step of controlling a packet data transmission timing to each terminal by permitting the terminals having the interference-suppressed relationship to transmit predetermined packet data and permitting the terminals having the mutually-interfered relationship to transmit the packet data by time sharing according to the determined combination.
    • 本发明的目的是实现一种分组调度方法及其装置,其以抑制由分组数据信号之间的干扰导致的通信质量恶化的方式提高发送和接收的分组数据的吞吐量。 分组调度方法包括接收从多个终端发送的无线信号的每一个的步骤,确定具有干扰抑制关系的终端的组合和多个终端之间具有相互干扰关系的终端的确定步骤 基于所接收的各个信号,以及通过允许具有干扰抑制关系的终端来发送预定分组数据并允许具有相互干扰关系的终端来发送分组数据来控制到每个终端的分组数据传输定时的步骤 通过根据确定的组合进行时间分配。

    • A radio terminal receives a directional multibeam from a radio base station and obtains each of correlation between orthogonal code series of the received directional multibeam and its own orthogonal code series to determine an orthogonal code series having the highest autocorrelation and further advertises orthogonal code series identification information identifying this orthogonal code series to the radio base station through an uplink physical channel. In comparison with a previous technique, this can shorten the time to be taken until the radio base station recognizes an orthogonal code series having the highest autocorrelation and a satisfactory reception condition in the radio terminal. Thus, it is possible to increase the speed of the loop control between the radio base station and the radio terminal, thereby improving the throughput of a channel to be used for the transmission of user data.
    • 无线终端从无线基站接收定向多波束,并且获得接收的定向多波束的正交码序列与其自己的正交码序列之间的每个相关性,以确定具有最高自相关性的正交码序列,并进一步通告正交码序列识别信息 通过上行链路物理信道将该正交码序列识别到无线基站。 与之前的技术相比,这可以缩短在无线电基站识别无线电终端中具有最高自相关性和令人满意的接收条件的正交码序列之后的时间。 因此,可以提高无线基站与无线终端之间的环路控制的速度,从而提高用于发送用户数据的信道的吞吐量。
