摘要： Dedicated pilot signals are transmitted from a transmitting device to a receiving device through a multicarrier MIMO channel in addition to data signals and common pilot signals. The dedicated pilot signals may be used by the receiving device to validate whether a predetermined beamforming matrix (i.e., a beamforming matrix identified by the receiving device) was used by the transmitting device to precode the transmitted data. If a different beamforming matrix was used for the preceding, the receiving device may use this matrix to demodulate the received data.

摘要： Machine-readable media, methods, apparatus and system for transmitting ACK/NACK signal in a wireless communication system are described. In some embodiments, a sequence corresponding to one of acknowledge (ACK) information and non-acknowledge (NACK) information may be determined. Then, the sequence may be mapped onto a transmission channel for later transmission from the mobile station to a base station. In some embodiments, the transmission channel may be allocated with at least a part of three feedback mini-tiles (FMTs), wherein each of the FMTs comprises two subcarriers contiguous in frequency domain by six orthogonal frequency division multiplexing (OFDM) symbols contiguous in time domain and the three FMTs being discontinuous in frequency domain.

摘要： Embodiments of the present invention may help facilitate improved performance for high throughput, mobile wireless networks, e.g., IEEE 802.16m, mobile implementations for 3GPP Long Term Evolution (LTE) including LTE advanced mobile phone networks, and other types of high bandwidth networks. In some embodiments, provided are orthogonal sequences with desirable correlation properties for, e.g., 4-6 bits of information, among other things, typically achieving improved performance at varied vehicle speeds. In some embodiments, correlation distances for 6 bits may be less than 3.86, for 5 bits may be less than 3.12, and for 4 bits may be less than 1.95. Additionally, in some embodiments, dedicated coding for PFBCH information may be provided to achieve improved performance for most (if not all) information bits at a relatively wide range of vehicle speeds. Different code sequences for different tiles in one PFBCH channel may be applied for same messages to overcome error floors in high speed scenarios.
摘要翻译：本发明的实施例可以帮助促进针对高吞吐量的移动无线网络（例如IEEE 802.16m，用于包括LTE高级移动电话网络的3GPP长期演进（LTE））的移动实现以及其他类型的高带宽网络的改进的性能。在一些实施例中，所提供的是具有例如4-6位信息的期望相关特性的正交序列，其中通常在变化的车辆速度下实现改进的性能。在一些实施例中，6位的相关距离可以小于3.86，因为5位可能小于3.12，对于4位可能小于1.95。另外，在一些实施例中，可以提供用于PFBCH信息的专用编码，以在相对较宽的车速范围内为大多数（如果不是全部）信息比特实现改进的性能。一个PFBCH信道中的不同瓦片的不同码序列可以应用于相同的消息以克服高速场景中的错误帧。

摘要： Briefly, in accordance with one or more embodiments, data transmitted from a transmitter is received in a downlink channel, and channel quality data is fed back to the transmitter in a first uplink channel or in a second uplink channel. Channel quality data is feedback at a lower rate on the first uplink channel and channel quality data is feedback at a higher rate on the second uplink channel in the event there is a higher amount of data to be fed back. Link adaptation may be utilized to select a transmission rate on the second uplink channel, wherein the transmission rate is selected based at least in part on a channel condition or a user location.
