    摘要: A wireless communication device for receiving a frame (200) corresponding to a transmission time interval, the frame having a control channel (210) including at least two control channel elements (212, 214) and an embedded bit sequence, the location of which indicates a portion of the control channel used for radio resource assignment, wherein the portion of the control channel used for radio resource assignment may be less than the entire control channel of the frame having the embedded bit sequence, and wherein the at least two frames may use different portions of the control channel for radio resource assignment.

    摘要: A method (400, 500) and apparatus for synchronization for a wireless communication device (300) using multiple synchronization channels. An initial cell search can be performed (420) by the wireless communication device (300). During the initial cell search, a primary synchronization symbol can be acquired (430) only on a center synchronization channel of a plurality of synchronization channels. The plurality of synchronization channels can include the center synchronization channel and a plurality of secondary synchronization channels. The primary synchronization symbol can be associated with the plurality of secondary synchronization channels. A frequency translation can be executed (460) to change a receive channel to acquire one of the secondary synchronization channels.

    摘要: A method and apparatus is provided for transmitting an orthogonal frequency domain multiple access (OFDMA) signal including a synchronization channel signal transmitted within a localized portion of a bandwidth of the OFDMA signal, the synchronization channel signal having predetermined time domain symmetry within the localized portion of the bandwidth and including information for providing at least partial cell identification information. The synchronization channel signal enables an initial acquisition and cell search method with low computational load which provides OFDMA symbol timing detection and frequency error detection and frame boundary detection and cell specific information detection in an OFDMA system supporting multiple system bandwidths, both synchronized and un-synchronized systems, a large cell index and an OFDMA symbol structure with both short and long cyclic prefix length.
