    • The invention relates to a method for scheduling resources for uplink transmissions in a radio access network comprising access points which own pre-assigned resources. The invention also relates to an access point (5-7), a user terminal (1-4) and an access point controller 8. Characteristic features of the invention are that each AP places its resources to the disposition of other APs in the access network, and that an AP (7) transmits a blocking signal (BLOCK R3) if it does not allow a UT (3) , which is served by an AP (5) in another cell, to use its resources (R3). A UT that detects a blocking signal from an AP that owns the resources on which the UT is transmitting immediately stops transmission on said resources. The signal quality of a detected blocking signal may be used for setting the transmission power on the resources the UT has borrowed from the AP which transmits the blocking signal. Based on statistics on the APs which transmit blocking signals long-term pre-allocation of resources among the APs is made.
    • 本发明涉及一种用于在包括具有预分配资源的接入点的无线电接入网络中调度用于上行链路传输的资源的方法。 本发明还涉及接入点(5-7),用户终端(1-4)和接入点控制器8.本发明的特征是每个AP将其资源放置在接入中的其他AP的配置 并且如果AP(7)不允许由另一小区中的AP(5)服务的UT(3)使用其资源(R3),则AP(7)发送阻塞信号(BLOCK R3)。 检测来自拥有UT发送的资源的AP的阻塞信号的UT立即停止在所述资源上的传输。 检测到的阻塞信号的信号质量可以用于设置UT从发送阻塞信号的AP借用的资源上的发送功率。 基于传输阻塞信号的AP的统计数据,进行了AP间的资源长期预分配。

    • Radio resources are allocated to communication between a mobile station (40) and a base station (20). The available set of radio resources may comprise radio resources primarily assigned to a neighbouring cell if the 5 mobile station (40) experience an instantaneous low level of co-channel interference from such neighbouring cells. The existence of interference is preferably deduced from signal quality measurements of pilot signals. The allocation may concern uplink and/or downlink (54) communication. Devices (41) for performing the measurements are located in the mobile station (40), while devices for performing the evaluation (22), selection (23) and actual allocation (24) can be placed in different parts of the communications system- in the mobile station (40), in a base station (20) or In a core network node (70), or as a distributed means.
    • 无线电资源被分配给移动台(40)和基站(20)之间的通信。 如果5个移动站(40)经历来自这些相邻小区的同信道干扰的瞬时低电平,则可用的一组无线电资源可以包括主要分配给相邻小区的无线电资源。 干扰的存在优先从导频信号的信号质量测量推导出来。 该分配可以涉及上行链路和/或下行链路(54)通信。 用于执行测量的设备(41)位于移动台(40)中,而用于执行评估(22),选择(23)和实际分配(24)的设备可以放置在通信系统的不同部分 移动台(40),基站(20)或核心网络节点(70)中,或作为分布式装置。
