    • A burst may include a three-bit tail sequence derived from a four-bit Enhanced General Packet Radio Service (EGPRS)-2 tail sequence. A legacy wireless transmit/receive unit (WTRU) may be multiplexed onto an Orthogonal Sub-channel (OSC) resource, and may receive a burst including four-bit Quadrature Phase Shift Keying (QPSK)-type tail sequences that decode to legacy three-bit Gaussian Minimum Shift Keying (GMSK)-type or 8PSK-type tail sequences. The legacy WTRU processes the tail sequences, unaware that the burst was received on an OSC sub-channel or that the tail sequences were encoded as QPSK-type tail sequences. An OSC QPSK tail sequence may be chosen such that it corresponds to the legacy GMSK tail sequence format when decoded on an OSC sub-channel, but also so that a power-versus-time mask, power constraint, or other criteria on the other MUROS sub-channel may be optimized. Different tail sequences may be used in OSC bursts, depending upon whether the WTRUs multiplexed onto a timeslot are legacy WTRUs or include OSC-specific features.
    • 突发可以包括从四比特增强型通用分组无线业务(EGPRS)-2尾部序列导出的三比特尾部序列。 传统的无线发射/接收单元(WTRU)可以被复用到正交子信道(OSC)资源上,并且可以接收包括四码相位相移键控(QPSK)型尾部序列的突发, 位高斯最小移位键控(GMSK)类型或8PSK型尾序列。 遗留WTRU处理尾部序列,不知道在OSC子信道上接收到突发,或者尾部序列被编码为QPSK型尾部序列。 可以选择OSC QPSK尾部序列,使得其在OSC子信道上解码时对应于传统GMSK尾序列格式,而且还使得功率对时间掩码,功率约束或其他MUROS上的其他标准 子通道可能被优化。 根据多路复用到时隙上的WTRU是否是传统的WTRU或包括OSC特有的特征,可以在OSC突发中使用不同的尾部序列。
