上行信号的发送时间确定方法及设备
摘要：
本发明实施例提供一种上行信号的发送时刻时间确定方法及用户设备，方法包括：用户设备确定该用户设备的定时提前组中的参考小区；所述用户设备根据所述用户设备接收到所述参考小区的下行信号的时间和所述定时提前组的TA值，确定所述定时提前组的上行信号的发送时间。本发明实施例解决了现有技术中没有给出用户设备如何确定TA组的上行信号的发送时间的问题，从而保证了用户设备根据确定的发送时间发送的上行信号到达基站的时间与基站期望其到达时间的误差在可接受范围之内。
摘要（英）：

An embodiment of the invention provides a method and user equipment for determining time of a sending moment of uplink signals. The method includes that the user equipment determines a reference cell in a timing advance group of the user equipment; and the user equipment determines sending time of uplink signals of the timing advance group according to time that the user equipment receives downlink signals of the reference cell and a timing advance (TA) value of the timing advance group. The embodiment solves the problem in the prior art that the user equipment can not determine the sending time of the uplink signals of the TA group, and therefore an error between time for the uplink signals sent by the user equipment according to determined sending time to arrive a base station and arriving time expected by the base station is made sure to be within an acceptable range.
