Abstract: PROBLEM TO BE SOLVED: To provide techniques of efficiently performing signal acquisition in a wireless communication system.SOLUTION: Each base station transmits a TDM pilot 1 generated with a PN1 sequence and a TDM pilot 2 generated with a PN2 sequence. Each base station is assigned a specific PN2 sequence that uniquely identifies that base station. A terminal uses the TDM pilot 1 to detect the presence of a signal and uses the TDM pilot 2 to identify base stations and obtain accurate timing. For signal detection, the terminal performs delayed correlation on received samples and determines whether a signal is present. If a signal is detected, the terminal performs direct correlation on the received samples with the PN1 sequences for K1 different time offsets and identifies K2 strongest TDM pilot 1 instances. For time synchronization, the terminal performs direct correlation on the received samples with the PN2 sequences to detect the TDM pilot 2.
Abstract translation: 要解决的问题：提供在无线通信系统中有效地执行信号获取的技术。解决方案：每个基站发送用PN1序列产生的TDM导频1和用PN2序列生成的TDM导频2。 为每个基站分配唯一标识该基站的特定PN2序列。 终端使用TDM导频1来检测信号的存在，并使用TDM导频2来识别基站并获得准确的定时。 对于信号检测，终端在接收到的采样上执行延迟相关，并确定信号是否存在。 如果检测到信号，则终端对接收到的样本与用于K1不同时间偏移的PN1序列进行直接相关，并识别K2最强的TDM导频1实例。 对于时间同步，终端对PN2序列的接收样本进行直接相关，以检测TDM导频2。

Abstract: PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate defining new control channels in legacy wireless networks.SOLUTION: Control data resources for new systems are defined in the legacy wireless network specification. Legacy devices are still supported after new control data resources are implemented. The new control data resources are reserved over the general data resources to avoid the interference over legacy control and reference signal resources (S802). In addition, new system devices create a substantially non-interfered global control segment not including data communication resources over new control resources (S804). Control data are transmitted over the segment using beacon-based technologies, reuse schemes, and/or the like (S806).
Abstract translation: 要解决的问题：提供有助于在传统无线网络中定义新控制信道的系统和方法。解决方案：传统无线网络规范中定义了新系统的控制数据资源。 在实施新的控制数据资源之后，仍然支持传统设备。 新的控制数据资源通过一般数据资源保留，以避免对传统控制和参考信号资源的干扰（S802）。 另外，新的系统设备创建一个基本上不受干扰的全局控制段，不包括新的控制资源上的数据通信资源（S804）。 控制数据通过使用基于信标的技术，重用方案等的片段（S806）来传送。

Abstract: PROBLEM TO BE SOLVED: To provide a channel estimation method which reduces estimation error even in the edge of a given subband.SOLUTION: Pilot signals are received (504) within a given subband. A determination is made as to whether a subcarrier of interest is near the edge of a subband. If the given carrier is near the edge of a subband, pilot signals received in a neighboring subband are utilized (508). The pilot signals of the entire neighboring subband or a predetermined portion of the neighboring subband are utilized to estimate the channel response (512). If the assigned subcarrier is not near the edge of a subband, neighboring pilots need not be considered and the channel response is estimated (512) without the use of pilot signals in neighboring subbands.

Abstract: PROBLEM TO BE SOLVED: To provide dynamic resource allocation systems, apparatus, and methods for selectively improving the ability of a receiver to determine a channel estimate in an OFDMA system.SOLUTION: A wireless communication system 100 can use a common pilot channel configuration to aid channel estimation in receivers in communication with the system. A receiver may be unable to demodulate received data due to an inaccurate channel estimate. The receiver can communicate to a transmitter in the system a request for additional channel estimation resources. The wireless communication system can provide additional channel estimation resources by inserting dedicated pilot channels into one or more of the frequencies allocated to symbols for the receiver. If the receiver is still unable to demodulate the received data, the wireless communication system can incrementally insert additional pilot channels in the symbol associated with the receiver.
