    • A method for transmitting an uplink channel sounding pilot is used in the Long Term Evolution Project. The method includes: receiving, by a User Equipment, an uplink channel sounding pilot scheduling signaling; and transmitting, by the User Equipment, an uplink channel sounding pilot according to an indication in the uplink channel sounding pilot scheduling signaling. The uplink channel sounding pilot scheduling signaling includes one of or a combination of indication information including transmission starting time, a transmission period, duration, a subcarrier index, a subframe index, a long block index and a frequency band of the uplink channel sounding pilot. A system for transmitting an uplink channel sounding pilot, a base station and a User Equipment are also disclosed. With the use of the invention, a User Equipment may be dynamically scheduled to transmit an uplink channel sounding pilot, a solution for carrying the uplink channel sounding pilot scheduling signaling is provided, and a solution for determining the position of the uplink channel sounding pilot in the subframe is also be provided, thereby the position of the uplink channel sounding pilot in the subframe can more accurately reflect the conditions of the channel on which uplink and/or downlink processing is performed according to the uplink channel sounding pilot.
    • 在长期演进项目中使用用于发送上行链路信道探测导频的方法。 该方法包括:由用户设备接收上行信道探测导频调度信令; 并且根据上行链路信道探测导频调度信令中的指示,由用户设备发送上行链路信道探测导频。 上行链路信道导频调度信令包括上行信道探测导频中的发送开始时间,发送周期,持续时间,子载波索引,子帧索引,长块索引和频带之间的指示信息之一或组合。 还公开了一种用于发送上行链路信道探测导频,基站和用户设备的系统。 利用本发明,用户设备可以被动态调度以发送上行链路信道探测导频,提供用于携带上行链路信道探测调度信令的解决方案,以及用于确定上行链路信道探测飞行员的位置的解决方案 还提供子帧,由此,子帧中的上行链路信道探测导频的位置可以更准确地反映根据上行链路信道探测导频执行上行链路和/或下行链路处理的信道的条件。

    • A method, a system and a device for indicating and transmitting the preamble are used to solve the problem existing in the prior art, which reduces the resource utilization efficiency due to that the user equipment (UE) sends the preamble to the evolution base station through the physical random access channel (PRACH) selected by itself in the present random access. The method includes: determining the channel signature associated with the PRACH assigned to the terminal side; sending the determined channel signature to the terminal side, and indicating the terminal side to transmit the preamble using the PRACH associated with the channel signature. Adopting said method can improve the resource utilization efficiency.
    • 用于指示和发送前导码的方法,系统和设备用于解决现有技术中存在的问题,这降低了资源利用效率,这是由于用户设备(UE)将前导码发送到演进基站,通过 在当前随机接入中自身选择的物理随机接入信道(PRACH)。 该方法包括:确定与分配给终端侧的PRACH相关联的信道签名; 将确定的信道签名发送到终端侧,并且指示终端侧使用与频道签名相关联的PRACH来发送前导码。 采用该方法可以提高资源利用效率。
