摘要： Systems and methods of providing a NPRACH preamble in a multefire system are described. A UE configured for multefire NB-IoT or eMTC operation receives, from an eNB, access information that includes a SIB on a narrowband channel of an unlicensed band. Based on the access information, the UE transmits a NPRACH preamble in two or six contiguous uplink subframes. The NPRACH preamble is transmitted in two or six contiguous subframes. When two subframes are used, four symbol groups each having a 266.7 μs CP and two symbols are transmitted without a gap therebetween. When six subframes are used, four symbol groups each having a 266.7 μs CP and five symbols are transmitted without a gap therebetween.

摘要： The present disclosure provides apparatuses, systems, methods, and machine readable storage medium for communications in a Narrow Band Internet of Things (NB-IoT) system in a sub-1 GHz band. In an embodiment, an apparatus for a user equipment (UE) includes a memory interface and a processor. The memory interface is operable to receive a configuration of a frame from a memory, the frame is to be used for communications in a Narrow Band Internet of Things (NB-IoT) system in a sub-1 GHz band, wherein the frame includes one or more anchor channels and one or more data channels. The processor is operable to encode uplink (UL) communication data for a base station or decode downlink (DL) communication data from the base station based on the configuration of the frame.

摘要： A method and apparatus is disclosed herein for resource allocation in a wireless communication system are disclosed. In one embodiment, the method comprises allocating portions of the resources available to a subset of base stations of the plurality of base stations to serve a subset of UTs from clusters of base stations with cluster sizes including at least one with two or more base stations, where each of the portions of resources are allocated to serve one UT via a user-dependent cluster of base stations; and scheduling UT transmissions over the subset of base stations and scheduling slots, wherein within each of the scheduling slots one or more user terminals are scheduled for transmission, each by its user-dependent cluster of base stations.

摘要： A telecommunication network may operate to enable a wake up signals (WUSs) within the telecommunication network. A mobility management entity (MME) may estimate a coverage enhancement (CE) level of a user equipment (UE), determine, based on the CE level, a number of repetitions for a wake up signal (WUS) for the UE, and cause a WUS for UE to be transmitted to a radio access network (RAN) node corresponding to the UE. The RAN node may inform the MME that the RAN node has disabled the WUS feature, and may cause system information to be broadcast to UEs in IDLE mode, indicating that the WUS feature of the RAN node has been disabled. A UE may determine a paging occasion (PO) determine a maximum WUS duration, minimum offset, and start location of the WUS.

摘要： Described herein are methods and apparatus for implementing discontinuous reception (DRX) states in user equipments (UE) in order to conserve battery power. In particular, methods and apparatus for signaling the UE to transition between different DRX states using L1 signaling such as over the physical downlink control channel (PDCCH) are described.
