摘要： Orthogonal Frequency Division Multiplexing (OFDM) is a typical multi-carrier technique that has been applied by many advanced wireless communication systems, e.g., 3GPP Long Term Evolution (LTE) and WiMAX. In order to support high mobility transmission, the sub-carrier spacing of multi-carrier systems is made large enough to overcome the Doppler frequency offset. However, this large sub-carrier spacing results in lower transmission efficiency since the CP (Cyclic Prefix) consumes a considerable of radio resources. The present invention provides an adaptive scheme to determine the sub-carrier spacing in which the default sub-carrier spacing is set to support lower mobility, while the adaptively adjusted sub-carrier spacing based on User Equipment (UE) mobile velocities is set to support higher mobility.
摘要翻译：正交频分复用（OFDM）是一种典型的多载波技术，已经被许多先进的无线通信系统应用，例如3GPP长期演进（LTE）和WiMAX。为了支持高移动性传输，多载波系统的子载波间隔足够大以克服多普勒频率偏移。然而，由于CP（循环前缀）消耗相当多的无线电资源，所以这种大的子载波间隔导致较低的传输效率。本发明提供一种自适应方案，用于确定其中默认子载波间隔被设置为支持较低移动性的子载波间隔，而基于用户设备（UE）移动速度的自适应调整的子载波间隔被设置为支持更高的流动性

摘要： A cellular phone system where a random access channel burst has a preamble comprising two Zadoff-Chu sequences to mitigate the effects of Doppler Frequency Offset. Upon reception of a random access channel burst by a base station, division is applied to the two sequences recovered from the preamble of the received burst to provide a quotient sequence. For some embodiments, the base station correlates the quotient sequence with a Zadoff- Chu sequence to identify the user equipment that transmitted the random access channel burst. Other embodiments are described and claimed.

摘要： The present invention provides a transmission method and apparatus for cancelling inter-carrier interference in wireless communication systems. Particular carriers are not used for data transmission but carry weighted data to cancel the ici interference of a first group of interfering sub-carriers onto a second group of victim sub-carriers. The weights are inversely proportional to the frequency offset between the interfering sub-carriers and the victim sub-carriers.

摘要： The present invention provides a space-time-frequency encoding and decoding method and apparatus used in a wireless communication system. With the encoding method provided in the invention, transmission code words and their redundant elements are properly allocated on space-time-frequency units, so that the transmission codes and their partial redundancies can be transmitted via different antennas. Accordingly, at the receiving side, the redundant elements and the corresponding code word elements can be combined, so as to enhance the SNR and diversity gains for a part of the elements in the code words, and hence enhance the reception quality for the overall data stream.
