摘要： A linear iterative channel estimation scheme and corresponding pilot allocation scheme are provided to perfect a channel model that cancels the Inter- Carrier Interference (ICI) for multi-carrier systems (e.g., OFDM, SC-FDMA, MC- CDMA, etc.) under high mobility conditions. Two issues of the linear iterative channel estimation scheme of the channel model, namely, overloaded pilots and increased Gauss noise are specifically addressed by exemplary embodiments. With the iterative channel estimation scheme provided by the present invention, the minimum pilot number is equal to the length of multi-path delay, and the Gauss noise is not increased.

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。本发明提供了一种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的自适应方案，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： 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.

摘要： A technique for operating a wireless communications system that supports multi-user multiple-input multiple-output (MU-MIMO) communications between a base station and multiple mobile stations involves generating inter-cell interference information at the mobile stations and providing the inter-cell interference information to the base station. The base station uses the inter-cell interference information to calculate channel quality indicators (CQIs) and then makes scheduling decisions in response to the CQIs. Data is transmitted from the base station to the mobile stations according to the scheduling decisions.

摘要： The invention provides methods and apparatus for transmitting and receiving a source data block in a wireless communication system using hybrid automatic retransmission request protocol. According to the scheme provided by the invention, at transmitting side, the source data block or part of source data block that is not decoded correctly at receiving side is divided into a plurlaity of data segements, each the plurality of data segments may be paded with known data to expand the data segments to be a predetermined lengthen, the data segment is encoded with linear code to be a data packet including the data segment and a redundancy information segment or including only redundancy information, and after that the encoded data packets are transmitted. At the receiving side, when each of the received data packets includes a data segment and a redundancy information segment, decoding is performed directly based on the received data packet, decoding is performed based on the received reduandancy information segment and an data segment and redundancy information segment extracted from buffered data packets with a first and second chance to restore the data segment that is not decoded correctly in previous decoding processing. With the additional decoding chance, the scheme provided by the invention can improve decoding probability and thus the transmission efficiency of the system.

摘要： In multi-carrier systems, distributed resource allocation of the resources of multiple user equipments (UEs) can result in better frequency diversity gain but can also induce Inter-Carrier Interference (ICI) between UEs. This ICI can become quite serious in a high mobility environment. Based on a novel radio channel model for ICI cancellation in multi-carrier systems and an iterative channel estimation scheme for ICI cancellation in multi-carrier systems, the present invention provides a simplified equalization scheme in the frequency domain to determine and remove ICI of both a targeting UE as well as other UEs.
