Vertaling van "frequency division multiple access" in Chinees
频分多址
The first generation of mobile communication system using frequency division multiple access (FDMA) analog modulation, the system is the fundamental flaw of the spectrum utilization low, signaling interfere with voice service.
第一代移动通信系统采用频分多址（FDMA）的模拟调制方式，这种系统的主要缺点是频谱利用率低， 信令干扰话音业务。
the network hub platoon consists of the TDMA and frequency division multiple access (FDMA) multiband sections and the baseband and hub support sections
网络中枢排由时分多址和频分多址（FDMA）多频段分队以及基带和中枢保障分队组成
Figure 1 schematically illustrates a mobile (cellular) telecommunication system 1 in which users of mobile telephones 3-0, 3-1, and 3-2 can communicate with other users (not shown) via a base station 5 and a telephone network 7. In this embodiment, the base station 5 uses an orthogonal frequency division multiple access (OFDMA) technique for transmitting the downlink data to the mobile telephones 3; and the mobile telephones 3 use a single carrier frequency division multiple access (FDMA) technique to transmit their uplink data to the base station 5. The base station 5 is responsible for allocating resources in both the uplink and the downlink for each mobile telephone 3 and informs each scheduled mobile telephone 3 of its allocations using a number of CCEs in the PDCCH. The present invention has specific relevance to the way in which the base station 5 allocates the CCEs for resource allocation.
图1图解说明了移动（蜂窝）通信系统1，其中，移动电话3-0、3-1和3-2的用户可通过基站5和电话网络7与其他用户（未显示）通信。在该实施例中，所述基站5使用正交频分多址（OFDMA）技术将下行数据传输给移动电话3；所述移动电话3使用单载波频分多址（FDMA）技术将其上行数据传输给基站5。所述基站5负责在用于每个移动电话3的上行链路和下行链路中分配资源，并使用PDCCH中的多个CCE为每个调度移动电话3通知其分配情况。本发明特别涉及基站5分配用于资源分配的CCE的方法。
The present invention relates to control signalling for the allocation of resources within a communication system. The invention has particular, although not exclusive relevance to the efficient allocation of control channel resources used to signal the allocation of physical resource blocks (PRBs) for uplink and/or downlink user data communications in a frequency division multiple access (FDMA) communication system.
本发明涉及用于在通信系统内进行资源分配的控制信令。本发明特别关于（但并不限于）用于在频分多址（FDMA）通信系统中对用于上行和/或下行用户数据通信的物理资源块（PRB）的分配进行信令的控制信道资源的有效分配。
