    • PROBLEM TO BE SOLVED: To carry out interference level measurement on each available channel of the frequency band for each radio link to be commissioned channels, in a method of channel allocation in a fixed radio link network.
      SOLUTION: Based on the interference measurements, best transmission and reception channels for the link are selected. Thereafter, the radio link can be commissioned and measurements in the next radio link to be commissioned can be started. Instead of using a fixed and pre-set channel for the fixed radio link, a channel is assigned autonomously and automatically when commissioning the link, depending on interference measurement results and/or distance measurement results. The possibility for automatic channel selection decreases the amount of commissioning work by removing the need for detailed frequency planning and fixed channel setting at the factory for each radio.

    • 要解决的问题:在固定无线电链路网络中的信道分配的方法中,对要被调试的每个无线电链路的频带的每个可用信道执行干扰电平测量。

      解决方案:基于干扰测量,选择链路的最佳发送和接收信道。 此后,可以对无线电链路进行调试,并且可以开始下一个无线电链路中的测量。 代替固定无线电链路使用固定和预设信道,根据干扰测量结果和/或距离测量结果调试链路时,自动和自动分配信道。 自动频道选择的可能性通过消除在每个广播的工厂需要详细的频率规划和固定频道设置来减少调试工作量。 版权所有(C)2008,JPO&INPIT

    • An access node /base station is allocated one or more root sequences for use with RACH preambles in the cell. The access node broadcasts an index for one of the root sequences and a basic cyclic shift parameter. A user equipment UE receives the index and parameter, determines all of the root sequences that are allocated to the cell (directly from the index and inherently from it if more than one root is allocated), and selects a sequence from among all cyclic shifts (including zero shift) of all of the allocated root sequences. The access node is required to make available in the cell a predetermined minimum number of cyclic shifts, but by selecting its sequence from among all cyclic shifts of all allocated root sequences, the UE's selection is not limited to be from among that minimum number. The UE sends on the RACH a preamble signal with the selected sequence.
    • 为接入节点/基站分配一个或多个根序列,以便与小区中的RACH前导码一起使用。 接入节点广播一个根序列的索引和基本的循环移位参数。 用户设备UE接收索引和参数,确定分配给小区的所有根序列(直接来自索引,并且如果多于一个根被分配则固有地根据该根序列),并从所有循环移位中选择一个序列 包括所有分配的根序列的零移位)。 接入节点需要在小区中提供预定的最小数量的循环移位,但是通过从所有分配的根序列的所有循环移位中选择其序列,UE的选择不限于该最小数目。 UE以所选择的序列在RACH上发送前同步码信号。

    • A detect decision is made by non-coherently combining results from correlating a preamble (CAZAC) sequence with base/root sequences used in the cell and setting a detection threshold based on those combined results. Another threshold can be set based on coherently combining results from correlating the preamble sequence, in which case the detect decision is based on satisfying either one of the thresholds. Where the sequence repeats in the same preamble, the results that are combined are from correlating the first instance of the CAZAC sequence and from correlating the second instance of the CAZAC sequence. Where the sequence does not repeat, different segments of the CAZAC sequence, each less than the whole and not necessarily of the same length, are correlated for a partial correlation on each segment, then the segments are combined and used to set the detection threshold. Detection may be done in stages, adjusting the threshold after the first stage based on comparing the results of non-coherent and coherent combining.
    • 通过非相干地组合来自将前导码(CAZAC)序列与在小区中使用的基本/根序列相关联的结果并基于那些组合的结果设置检测阈值来进行检测决定。 可以基于相关地组合来自相关前同步码序列的结果来设置另一阈值,在这种情况下,检测决定基于满足阈值中的任何一个。 在同一前导码中重复序列的情况下,组合的结果来自将CAZAC序列的第一个实例与CAZAC序列的第二个实例相关联。 在序列不重复的情况下,CAZAC序列的不同部分(每个小于整体而不一定相同的长度)与每个片段上的部分相关相关,然后将片段组合并用于设置检测阈值。 可以分阶段地进行检测,基于比较非相干和相干组合的结果来调整第一阶段之后的阈值。
