    • An apparatus and method for processing fast feedback payload data to generate symbols for transmission through a fast feedback channel in a wireless network are presented. The technique first encodes payload data using a tail biting convolutional code. The encoded bits are then de-multiplexed to five different data subblocks in a sequential fashion. Subblock interleaving is then used to interleave the data of the subblocks according to a predetermine scheme. A bit selector then selects interleaved subblock bit for output. The selected bits may then be modulated by a modulator using quadrature phase shift keying (QPSK). The resulting symbols may then be mapped to a predetermined fast feedback subcarriers within a feedback channel.
    • 提出了一种用于处理快速反馈有效载荷数据以生成用于通过无线网络中的快速反馈信道进行传输的符号的装置和方法。 该技术首先使用尾巴卷积码对有效载荷数据进行编码。 然后,编码比特以顺序方式解复用到五个不同的数据子块。 然后使用子块交织来根据预定方案来交织子块的数据。 然后,位选择器选择交织的子块位以进行输出。 然后可以使用正交相移键控(QPSK)由调制器调制所选择的比特。 所得到的符号然后可以被映射到反馈信道内的预定快速反馈子载波。

    • 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.
    • 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。
