    摘要: 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.

    摘要: A License Assisted Access (LAA) enhanced NodeB (eNB), user equipment (UE) and communication methods therebetween operating in a Long Term Evolution unlicensed band (LTE-U) are generally described. The eNB may transmit a request to the UE for information regarding a Wireless Local Area Network (WLAN) over which the UE may be able to communicate. The WLAN information may include an LTE-U channel and time window for reporting. The UE may obtain the WLAN information through communication with an access point (AP). Measurement information of the LTE-U channel may also be obtained by or on behalf of the UE. The UE may transmit the WLAN information to the eNB. The eNB may use the WLAN information or submit the WLAN information to a network entity to perform channel selection, UE grouping or localization, appointing delegate UEs to perform channel sensing or scheduling UEs in a same group or proximity.

    摘要: 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.
