摘要： A method and apparatus for reducing the peak to average power ratio of an OFDM signal. The method involves operating on the signal only after it is converted to the time domain where the signal is compared to a power threshold and any signal above the power threshold is considered undesirable. A reduced signal is produced by reducing the magnitude to the power threshold whenever it exceeds that threshold. The delta between the original signal and reduced signal is the clipped signal. The clipped signal is multiplied by a g-function, and then subtracted from the original signal to produce a first iteration of a peak-reduced signal. The process can then be repeated using the first peak-reduced signal in place of the original signal to produce the second iteration of a peak-reduced signal. This process can be repeated each time bringing the peaks closer to the power threshold. The g-function can be defined either to allow for per-symbol cyclic signal processing or non-cyclic processing that is symbol time independent.

摘要： Methods and systems for multi-protocol transmissions in shared spectrum are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. Generally, multi-protocol transmissions as described herein may be performed sequentially (e.g. in a time division multiplexing fashion) or concurrently (e.g. during the same or an overlapping time interval). For concurrent transmissions, an OFDM transmitter may be configured to map or assign the different OFDM signals to different subsets of the available OFDM subcarriers such that the data contained therein can be transmitted at the same or during an overlapping time interval. In one application, an LTE transmitter is configured to use different subsets of the LTE subcarriers for concurrent LTE and 802.11 transmissions that can respectively be decoded by LTE and 802.11 receivers.

摘要： A first radio network node (HBS1) adapts its physical cell identifier (PCI1) based on a comparison of its PCI1 to a second PCI (PCI2) used by a neighboring interfering second radio network node (e.g., another HBS2 or a macro node). The first radio network node HBS1 determines the second PCI based on one or more radio measurements performed on a cell 402 and/or on a UE 404 served by the second node. The adaptation of the cell identifier PCI1 is used for one or more radio network management tasks, e.g., resource management such as interference mitigation in a heterogeneous network, radio network planning, etc.

摘要： Methods and systems for multi-protocol beacon operation in shared spectrum (unlicensed band) are disclosed where an OFDM transmitter is configured to generate transmissions associated with one OFDM technology or protocol using subcarriers of another OFDM technology. In one application, an LTE transmitter (LTE-U) uses LTE subcarriers to generate an interpolated 802.11 (e.g. Wi-Fi) beacon transmission that can be understood by Wi-Fi receivers, for example to reserve the channel for a subsequent LTE transmission. For instance a W-LAN preamble is generated where STF and LTF fields consist in respectively 12 and 52 subcarriers mapped at their respective frequency locations among the 2048 LTE subcarriers with the remaining subcarriers set to 0. In some implementations, the use of beacons can be useful in implementations where it is desirable to gain prioritized access to reserve the channel. Examples of suitable LTE transmissions that would benefit from prioritized channel access include delay or time-sensitive LTE transmissions or transmissions that must occur within a certain time window and/or with a certain periodicity such as LTE control data or signals (e.g. PDCCH), and/or synchronization or reference signals such as the Discovery Reference Signal (DRS) for LAA-LTE). An LTE transmitter can exploit the 802.11 channel access to gain prioritized channel access for transmitting 802.11 Wi-Fi beacons generated using its LTE subcarriers to ensure LTE transmissions take priority over other types of LTE and/or Wi-Fi traffic.

摘要： A home base station (HBS) (104, 801) performs radio channel measurements to detect one or more user equipments (UEs) (107) not served by the HBS which may be in a potentially interfering environment caused at least in part by the HBS. A database (812) of historical channel data (channel fingerprinting) of the HBS coverage area is used to predict the channel conditions and expected interference signal power seen by the detected UE(s). Based on a combination of the radio measurements (813) and historical channel data, the HBS can accurately and adaptively reduce its transmit power to a level that reduces or eliminates interference with the detected UE(s), while also not significantly degrading communication quality between other UEs served by the HBS.
摘要翻译：家庭基站（HBS）（104,801）执行无线电信道测量以检测不由HBS服务的一个或多个用户设备（107），所述HBS可能至少部分地由HBS引起潜在的干扰环境。使用HBS覆盖区域的历史信道数据（信道指纹）的数据库（812）来预测检测到的UE看到的信道状况和预期的干扰信号功率。基于无线电测量（813）和历史信道数据的组合，HBS可以将其发射功率精确和自适应地降低到降低或消除对所检测到的UE的干扰的水平，同时也不会显着降低由HBS服务的其他UE。
