摘要： In one aspect of the teachings herein, a radio network node advantageously adapts the transmission duration of a synchronization signal with respect to transmission of the synchronization signal in different directions. For example, the radio network node uses a shorter transmission duration in beam directions that are associated with better reception conditions and a longer transmission duration in beam directions that are associated with poorer reception conditions. As a consequence of varying the transmission duration according to received-signal qualities known or expected for the different directions, the radio network node can shorten the overall time needed to complete one synchronization-signal transmission cycle and use less energy, as compared to using a more conservative, longer transmission time in all beam directions.
摘要翻译：在本文的教导的一个方面中，无线电网络节点有利地适应关于同步信号在不同方向上的传输的同步信号的传输持续时间。例如，无线电网络节点在与更差的接收条件相关联的波束方向上使用更短的传输持续时间，并且在与更差的接收条件相关联的波束方向上使用更长的传输持续时间。作为根据对于不同方向已知或预期的接收信号质量改变传输持续时间的结果，无线电网络节点可以缩短完成一个同步信号传输周期所需的总时间并且使用较少的能量，与使用更保守，所有波束方向的传输时间更长。

摘要： A method performed by a first communication node (511) in communication with a second communication node (512). The second node (512) is a receiver or transmitter of data in a frame (800). The frame (800) comprises one first set of time-frequency resources (801) reserved for control information, and a second set of time-frequency resources (802) reserved for data. The first node (511) determines that a third set (803) is to be used for communication of information with a third communication node (513). The information is control information, data information, or one or more signals related to one or more measurement procedures. The first node (511) determines a direction of communication in the third set (803), based on the information to be communicated. The first node (511) performs transmission or reception to or from the third node (513) in the determined direction, and in the third set (803).

摘要： Signal properties of a signal section (106) comprising a training sequence are compared with corresponding signal properties of other signal sections (108, 110). At a too large discrepancy, co-sequence interference is concluded to be present. The used signal property can preferably be a signal-to-noise ratio measure or a signal statistics measure. If the existence of co-sequence interference (102) is concluded, measures can be taken to avoid such interference and to mitigate the effects of the interference. A method for mitigating effects of co-sequence interference in channel estimation comprises a joint detection and estimation procedure performed under constrictions assuming presence of co-sequence interference.
摘要翻译：将包括训练序列的信号部分（106）的信号特性与其它信号部分（108,110）的相应信号特性进行比较。在一个太大的差异上，共序干扰得出结论。所使用的信号特性可以优选地是信噪比测量或信号统计测量。如果存在共序干扰（102），则可以采取措施避免这种干扰并减轻干扰的影响。用于减轻协同干扰在信道估计中的影响的方法包括在假设存在协同干扰的收缩下执行的联合检测和估计过程。
