    • Transmission of random access preamble structures within a cellular wireless network is based on the use of cyclic shifted constant amplitude zero autocorrelation (“CAZAC”) sequences to generate the random access preamble signal. A pre-defined set of sequences is arranged in a specific order. Within the predefined set of sequences is an ordered group of sequences that is a proper subset of the pre-defined set of sequences. Within a given cell, up to 64 sequences may need to be signaled. In order to minimize the associated overhead due to signaling multiple sequences, only one logical index is transmitted by a base station serving the cell and a user equipment within the cell derives the subsequent indexes according to the pre-defined ordering. Each sequence has a unique logical index. The ordering of sequences is identified by the logical indexes of the sequences, with each logical index uniquely mapped to a generating index. When a UE needs to transmit, it produces a second sequence using the received indication of the logical index of the first sequence and an auxiliary parameter and then produces a transmission signal by modulating the second sequence.
    • 蜂窝无线网络内的随机接入前同步码结构的传输是基于使用循环移位恒幅零自相关(“CAZAC”)序列来生成随机接入前同步信号的。 按照特定顺序排列预定义的序列集合。 在预定义的序列集合内,是序列的有序组,其是预定义序列集合的适当子集。 在给定的小区内,可能需要发信号通知多达64个序列。 为了最小化由于信令多个序列引起的相关开销,仅由服务于小区的基站发送一个逻辑索引,并且小区内的用户设备根据预定义的顺序导出后续索引。 每个序列都有唯一的逻辑索引。 序列的顺序由序列的逻辑索引识别,每个逻辑索引唯一映射到生成索引。 当UE需要发送时,它使用接收到的第一序列的逻辑索引的指示和辅助参数产生第二序列,然后通过调制第二序列来产生传输信号。

    • A method is described for operating a cellular network, where the cellular network uses a plurality of frequency division multiplexing (FDM) bands for wireless communication from user equipment (UE) to a base station (NodeB). At least one band-specific cell parameter is computed for at least one the plurality of FDM bands by a serving NodeB. The band-specific cell parameters are transmitted from the NodeB serving a first cell to a NodeB serving a second cell. The band-specific cell parameters may be computed in response to scheduling information and/or channel specific measurements made by the NodeB. A UE receives a first Power Configuration, a Second Power Configuration, and a Scheduling Message indicative of an FDM band from the set comprising at least from First FDM band and Second FDM band. UE transmits with the First Power Configuration if the Scheduling Message was indicative of First FDM band, and with the Second Power Configuration otherwise.

    • UE-initiated accesses within a cellular network are optimized to account for Doppler shift. A user equipment (UE) receives information that designates a particular access slot as high-speed and designates another access slot as low-speed within a given cell. The UE determines its relative speed to a serving base station (NodeB) within the cell. The UE selects either a baseline structure or an alternate structure if the relative speed is less than a threshold value or only an alternate structure if the relative speed exceeds the threshold value. The UE transmits a signal to the NodeB using the selected structure, such that the baseline structure is transmitted only in the designated low-speed access slot and that the alternate structure is transmitted only in the designated high-speed request slot.
    • UE发起的蜂窝网络中的接入被优化以考虑多普勒频移。 用户设备(UE)以特定小区的速度接收指定特定接入时隙的信息,并指定另一接入时隙为低速。 UE确定其与小区内的服务基站(NodeB)的相对速度。 如果相对速度小于阈值,则UE选择基线结构或替代结构,或者如果相对速度超过阈值,则UE选择替代结构。 UE使用所选择的结构向NodeB发送信号,使得仅在指定的低速接入时隙中发送基线结构,并且仅在指定的高速请求时隙中发送替代结构。

    • Transmitting a ACK/NACK response in a wireless cellular network by mapping the data value into a cyclic shifted version of a reference signal. A subframe is formed with a plurality of symbols with certain symbols designated as reference signal (RS) symbols. The receiver and transmitter both know when an ACK/NACK response is expected. If an ACK/NACK response is not expected, then an RS is inserted in the duration of symbols designated as RS symbols. If an ACK/NACK response is expected, then the ACK/NACK response is embedded in one or more of the symbols designated as RS symbols. The subframe is transmitted to a receiver, and the receiver can determine the ACK/NACK value in the RS symbol, if present, and also use the RS symbol for coherent demodulation of a CQI (channel quality indicator) or data.
    • 通过将数据值映射到参考信号的循环移位版本中,在无线蜂窝网络中发送ACK / NACK响应。 子帧由具有指定为参考信号(RS)符号的某些符号的多个符号形成。 接收机和发射机都知道何时预期ACK / NACK响应。 如果不期望ACK / NACK响应,则在指定为RS符号的符号的持续时间内插入RS。 如果期望ACK / NACK响应,则将ACK / NACK响应嵌入被指定为RS符号的一个或多个符号中。 子帧被发送到接收机,并且接收机可以确定RS符号中的ACK / NACK值(如果存在),并且还使用RS符号来进行CQI(信道质量指示符)或数据的相干解调。
