Abstract: A mobile device receives a signal, from a base station, comprising a primary synchronization sequence (PSS) and a secondary synchronization sequence (SSS). The mobile device utilizes two different sampling rates to perform the PSS synchronization and the SSS detection individually. For example, the mobile device synchronizes to the received PSS at a first sampling rate such as 0.96 MHz, which is determined based on the PSS transmission rate and/or the length of the received PSS. The mobile device detects the received SSS at a second sampling rate such as 1.92 MHz, which equals to the sampling rate for an analog-to-digital conversion at the mobile device. The received PSS and associated symbol timing are detected through the PSS synchronization to support the SSS detection. The detected SSS is used to acquire cell-specific parameters such as cell ID. The acquired cell-specific parameters ensure proper communications between the mobile device and the base station.

Abstract: A mobile device receives a signal comprising a PSS and a SSS. The mobile device performs iterative MFHT utilizing a reduced number of MFH branches. At each iteration, frequency offset estimation and Cell-ID detection are concurrently performed. An iteration starts with selecting initial frequency offsets spanning a frequency offset estimation range. The selected initial frequency offsets are placed in the MFH branches. A particular MFH branch with a maximum PSS correlation peak magnitude is selected at the iteration. A frequency offset estimate in the selected MFH branch is utilized for frequency control. The frequency offset estimation range utilized for the current iteration is reduced for the next iteration. A Cell-ID is declared if the Cell-ID is consistently detected not only within a particular iteration on the basis of having detected consistent cell ID information for the first and second halves of a radio frame, but also from iteration to iteration.

Abstract translation: 移动设备接收包括PSS和SSS的信号。 移动设备利用减少数量的MFH分支执行迭代MFHT。 在每次迭代时，同时执行频偏估计和小区ID检测。 迭代开始于选择跨越频率偏移估计范围的初始频率偏移。 所选择的初始频率偏移位于MFH分支中。 在迭代中选择具有最大PSS相关峰值幅度的特定MFH分支。 所选MFH分支中的频率偏移估计用于频率控制。 用于当前迭代的频率偏移估计范围在下一次迭代中减少。 如果基于已经检测到无线电帧的第一和第二半部分的一致的小区ID信息，而且从迭代到迭代，则不仅在特定迭代中一致地检测小区ID，否则将声明小区ID。

Abstract: A wireless communication device (e.g., generally, a device) includes a communication interface and a processor configured to support communications with one or more other devices. In an example of operation, the device supports first communications based on a first communication protocol with a first network coordinator device and identifies a second network coordinator device that operates based on a second communication protocol when supporting those first communications. The device also determines one or more operational parameters associated with the second network coordinator device. When one or more conditions is/are appropriate, the device interworks the first communications and second communications based on the second communication protocol with the second network coordinator device. The degree of interworking is based on one or more considerations associated with one or more of the first and second communication protocols, the first and second network coordinator devices, local and/or remote operating conditions, etc.

Abstract: Aspects of a method and system for an OFDM joint timing and frequency tracking system may include tracking carrier frequency and symbol timing in an Orthogonal Frequency Division Multiplexing (OFDM) signal based on at least a reference symbol set. A receiver frequency and timing may be adjusted based on the tracked carrier frequency and symbol timing. The carrier frequency may be tracked by generating an output signal as a function of a frequency offset Δf, and the symbol timing may be tracked by generating an output signal as a function of a guard time Δtg. The received OFDM signal may be fast Fourier transformed to generate the reference symbol (RS) set. The receiver frequency and timing may be adjusted coarsely prior to fine adjustment. The coarse receiver frequency and the timing adjustment may be based on processing a primary synchronization signal and a secondary synchronization signal.
