    • Methods and apparatus for sounding reference signals (SRS) configuration and transmission. The methods include receiving configuration of wireless transmit/receive unit (WTRU) -specific SRS subframes for transmitting SRS and upon receipt of a trigger, transmitting the SRS for a number of antennas. The SRS transmissions may occur in each subframe of a duration of WTRU-specific SRS subframes that start a number of WTRU-specific SRS subframes after a triggering subframe. For multiple SRS transmissions from multiple antennas, cyclic shift multiplexing and different transmission combs may be used. The cyclic shift for an antenna may be determined from a cyclic shift reference value. The cyclic shift determined for each antenna providing a maximum distance between cyclic shifts for the antennas transmitting SRS in a same WTRU-specific subframe. SRS transmissions from multiple antennas in the WTRU-specific subframe may be done in parallel. Methods for handling collisions between SRS and physical channels are presented.
    • 用于探测参考信号(SRS)配置和传输的方法和装置。 该方法包括接收用于发送SRS的无线发射/接收单元(WTRU)特定的SRS子帧的配置,并且在接收到触发时,发射用于多个天线的SRS。 SRS传输可以发生在触发子帧之后开始多个WTRU特定的SRS子帧的WTRU特定的SRS子帧的持续时间的每个子帧中。 对于来自多个天线的多个SRS传输,可以使用循环移位复用和不同的传输梳齿。 可以从循环移位参考值确定天线的循环移位。 为每个天线确定的循环移位提供了在同一WTRU特定子帧中发送SRS的天线的循环移位之间的最大距离。 来自WTRU特定子帧中的多个天线的SRS传输可以并行完成。 介绍了处理SRS和物理通道之间冲突的方法。
