摘要： A transmission of information within a wireless cellular network may include a first and second group of samples. A first group of samples is created comprising at least a first and a last subgroup, wherein the last subgroup is same as the first subgroup. A second group of samples created. A transformed set of samples produced by jointly transforming the created first and second group with a discrete Fourier transform (DFT). The transformed set of samples is expanded to produce an expanded set, and the expanded set is transformed with an inverse discrete Fourier transform (IDFT) to produce an OFDM symbol with a fractional payload. The first group of samples is a reference signal (RS), which is known to the receiver before the transmission occurs, while the second group of samples is information data.

摘要： A cell within cellular network includes user equipment (UE) that transmits data to a base station (eNB). When a UE does not have data to transmit, it may enter a low power mode (DRX) having silent intervals during which the eNB does not expect to receive a transmission from the UE and the UE is not required to monitor DL control channels from the eNB. While in DRX mode, the UE may detect an event, such as data ready for transmission or a need to request a timing adjustment (TA) update. The UE transmits a scheduling request indicator (SRI) to the eNB in response to detection of the event, wherein the SRI carries information identifying the triggering event.

摘要： 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.

摘要： 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.
摘要翻译： 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。
