    Abstract: PROBLEM TO BE SOLVED: To provide a newly improved time tracking loop for synchronizing the timing of a communication signal with the timing of a receiver which receives the communication signal.
    SOLUTION: A signal receiver quickly and highly precisely captures and tracks a received spread spectrum signal by using the accumulated object of overlapped samples. The accumulated object of the samples is formed by grouping the prescribed number of successive samples together. Then, the accumulated object of the overlapped samples is generated by overlapping the prescribed section of the accumulated object of the adjacent accumulated samples. The accumulated object of the overlap samples is generated, and transmitted to a timing discriminator, and a timing error showing a difference between the timing of the received spread spectrum signal and the timing of the signal receiver is determined. The timing discriminator compares the overlap accumulation signal transmitted first with the overlap accumulation signal transmitted the next, and determines the updated timing error. Afterwards, the timing of the receiver is adjusted according to the timing error. The accumulated object of the samples is overlapped so that the system timing can be more quickly adjusted than the case of using discrete samples.

    Abstract translation: 要解决的问题：提供一种新改进的时间跟踪环，用于使通信信号的定时与接收通信信号的接收机的定时同步。 解决方案：信号接收器通过使用重叠样本的累积对象，快速高精度地捕获并跟踪接收的扩频信号。 通过将规定数量的连续采样分组在一起而形成样本的累积对象。 然后，通过重叠相邻累积样本的累积对象的规定部分来生成重叠样本的累积对象。 生成重叠采样的累积对象，并将其发送到定时鉴别器，并且确定表示接收的扩展频谱信号的定时与信号接收机的定时之间的差的定时误差。 定时鉴别器将首先发送的重叠累加信号与下一次发送的重叠累加信号进行比较，并确定更新的定时误差。 然后，根据定时误差调整接收机的定时。 样本的累积对象重叠，使得可以比使用离散样本的情况更快地调整系统定时。 版权所有（C）2009，JPO＆INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide methodology or an algorithm efficient for evading loss of Walsh codes required to construct a high-speed channel.
    SOLUTION: Systems and techniques involve spread-spectrum communications using a scheduler 206, or similar component, configured to maintain a plurality of spreading sequence assignments and a plurality of available spreading sequences each being orthogonal to the assigned spreading sequences. Also, the scheduler 206 may be configured to select a spreading sequence from a group of the available spreading sequences having the same length. The selected spreading sequence is generated from a block of codes and is selected based on the number of the available spreading sequences that can be generated using the same block of codes.

    Abstract: The systems and methods described herein support efficient SDM operation in IAB networks. A first node receives a semi-static resource allocation from a CU based on at least one multiplexing capability of the first node. The first node also receives from the CU one or more resource conditions for using allocated resources of the semi-static resource allocation, and the first node communicates with a second node based on the semi-static resource allocation and the one or more resource conditions. The at least one multiplexing capability includes at least one of SDM or FDM, including full duplex or half duplex. The at least one multiplexing capability is also with respect to one or more transmission direction combinations of the first node.

    Abstract: The punctured pilot channel comprises information symbols of uncertain sign punctured into a sequence of pilot channel symbols of predetermined sign. The apparatus includes an information sign demodulation circuit for determining the sign of the information symbols in response to the pilot channel symbols. A continuous pilot generator generates a non-punctured pilot channel of predetermined sign from the information symbols and the pilot channel symbols. In a first embodiment, the information sign demodulator further comprises a dot product circuit for calculating a dot product of the pilot channel symbols and the punctured information symbols, and a threshold comparator for comparing the dot product to a predetermined threshold.
