    Abstract: Co-existence muting gaps can be included in an LTE protocol over unlicensed spectrum to enable a more efficient sharing with other wireless technologies, including wireless local area networks (WLANs). For example, an LTE protocol can be altered to include muting gaps that align with a WLAN beacon. In another example, a WLAN access point (AP) can create an information element (IE) that describes muting gaps available to WLAN stations (STAs) such that STAs can remain in a low power state until a muting gap is available. In yet another example, a cell tower and WLAN can be configured such that WLAN beacons occur when the cell tower is not transmitting during selected portions of LTE frames.

    Abstract: Systems and methods disclosed herein describe a centralized-processing cloud-based RAN (C-RAN or cloud-RAN) architecture that offers reduced front-haul data-rate requirements compared to common-public-radio-interface (CPRI) based C-RAN architectures. Base-band physical-layer processing can be divided between a BBU Pool and an enhanced RRH (eRRH). A frequency-domain compression approach that exploits LTE signal redundancy and user scheduling information can be used at the eRRH to significantly reduce front-haul data-rate requirements. Uniform scalar quantization and variable-rate Huffman coding in the frequency-domain can be applied in a compression approach based on the user scheduling information wherein a lossy compression is followed by a lossless compression.

    Abstract: A user equipment (UE) can reserve shared spectrum between two wireless protocols upon the request from a tower. For example, an enhanced node B (eNB or eNodeB) transmits a message to associated UEs including a set of candidate UEs, a length of time to reserve, and a frequency band to use. UEs perform medium sensing on the specified spectrum if a UE finds its identifier in the set of candidate UEs. Candidate UEs transmit a clear to send (CTS) message with channel reservation information if the medium is idle. A result of the success or failure of the CTS transmission attempt is sent back to the eNB. Upon receiving the feedback information from the UEs, the eNB starts sending data to those UEs that sent the positive feedback on the channel reservation.

    Abstract translation: 用户设备（UE）可以根据来自塔的请求来在两个无线协议之间预留共享频谱。 例如，增强节点B（eNB或eNodeB）向包括一组候选UE的相关UE发送消息，要预留的时间长度和要使用的频带。 如果UE在候选UE集合中找到其标识符，则UE在指定频谱上执行介质感测。 候选UE如果介质空闲，则发送具有信道预留信息的清除发送（CTS）消息。 CTS传输尝试的成功或失败的结果被发回到eNB。 在从UE接收到反馈信息之后，eNB开始向在信道预留上发送正反馈的那些UE发送数据。
