    • A cyclic shift of a reference signal is quantized as a combination of a cell specific cyclic shift with an outcome of a pseudo-random hopping, and an indication of the cell specific cyclic shift is broadcast in the cell. In one embodiment the cyclic shift is quantized as a modulo operation on a sum of the cell specific cyclic shift, the outcome of the pseudo-random hopping, and a user specific cyclic shift, in which case an indication of the user specific cyclic shift is sent in an uplink resource allocation and a user sends its cyclically shifted reference signal in the uplink resource allocated by the uplink resource allocation. The cyclic shift may also be quantized according to length of the reference signal as cyclic_shift_symbol=(cyclic_shift_value*length of the reference signal)/12; where cyclic_shift_value is between zero and eleven and cyclic_shift_symbol is the amount of cyclic shift given in reference signal symbols.
    • 参考信号的循环移位被量化为小区特定循环移位与伪随机跳变的结果的组合,并且在小区中广播小区特定循环移位的指示。 在一个实施例中,循环移位被量化为对小区特定循环移位,伪随机跳跃的结果和用户特定循环移位之和的模运算,在这种情况下,用户特定循环移位的指示是 在上行链路资源分配中发送,并且用户在由上行链路资源分配分配的上行链路资源中发送其循环移位的参考信号。 循环移位也可以根据参考信号的长度量化为cyclic_shift_symbol =(cyclic_shift_value *参考信号的长度)/ 12; 其中,cyclic_shift_value在零和十一之间,而cyclic_shift_symbol是参考信号符号中给出的循环移位量。

    • A method for signaling between a mobile apparatus (10) and a network node (12) is described. The method includes generating a message that includes a scheduling request. Determining whether a second indication (e.g., an acknowledgment) is to be transmitted in a sub-frame with the first indication is also included. The method includes, in response to a determination that the second indication is not to be included, the message is configured in a first configuration and, in response to a determination that the second indication is to be included, the message also includes the second indication and the message is configured in a second configuration. The first configuration is distinct from the second configuration. The method also includes sending the message, via a wireless transmitter, in the sub-frame. Apparatus and computer-readable media are also described.
