    • In a 3rd Generation Partnership Project, 3GPP, communication system a base station comprises a scheduler allocating communication resource of at least one of a Physical Uplink Shared CHannel, PUSCH, and a Physical Downlink Shared CHannel, PDSCH to a User Equipment (UE). The scheduling may either be a dynamic scheduling wherein a resource allocation for a single frame is provided to the UE or a persistent scheduling wherein a resource allocation for a plurality of frames is provided to the UE. A resource allocator assigns resource of a Physical Uplink Control CHannel, PUCCH, to the UE dependent on whether dynamic scheduling or persistent scheduling is performed by the scheduler for the UE. The UE transmits uplink control data on a physical uplink channel which is selected as the PUCCH or the PUSCH in response to whether persistent scheduling is used for the UE. The invention allows e.g. reduced PUCCH loading.
    • 在第三代合作伙伴计划3GPP中,通信系统基站包括向物理设备(UE)分配物理上行链路共享信道,PUSCH和物理下行链路共享信道中的至少一个的通信资源的调度器。 调度可以是动态调度,其中向UE提供单个帧的资源分配,或者持续调度,其中向UE提供多个帧的资源分配。 资源分配器根据UE的调度程序是否执行动态调度或持续调度,向UE分配物理上行链路控制信道PUCCH的资源。 响应于是否对UE使用持续调度,UE在被选择为PUCCH或PUSCH的物理上行链路信道上发送上行链路控制数据。 本发明允许例如 减少PUCCH负载。
