    • Structure of a multi-carrier flexible spectrum wireless cell is determined from received synchronization or broadcast channels of detected individual carriers. The determined structure is used to select an intended carrier for initial access or cell reselection to the flexible spectrum wireless cell. The structure may have carriers compatible with an earlier version (LTE/Release 8) of a communication standard and with a later version (LTE-A/Release 9). The received synchronization channels can inform of: relative positions of the individual carriers in a spectrum band of the multi-carrier structure; relative timing alignments of the received synchronization channels; contents of the received synchronization channels; and/or layer 1 cell-carrier identifiers. The synchronization channels may have a different structure as between the earlier and later versions, and the different structure is used to select the carrier that is compatible with the user equipment making the selection.
    • 从接收到的检测到的个体载波的同步或广播信道确定多载波灵活频谱无线小区的结构。 所确定的结构用于选择用于初始接入或小区重选的目的载波到灵活频谱无线小区。 该结构可以具有与通信标准的较早版本(LTE /版本8)和更高版本(LTE-A /版本9)兼容的载波。 所接收的同步信道可以通知:多载波结构的频谱带中各个载波的相对位置; 所接收的同步信道的相对定时对准; 收到的同步信道的内容; 和/或第1层小区载体标识符。 同步信道可以具有与较早版本和较新版本之间不同的结构,并且不同的结构用于选择与进行选择的用户设备兼容的载波。
