    Abstract: Apparatuses (including base stations and terminals), systems, and methods for supporting both wideband and narrowband communications are described. In one aspect, a base station supporting first type terminals operating on a first bandwidth and second type terminals operating on a second bandwidth is described, having an information formatter, a transceiver, and a controller. The information formatter generates a Low-end Master Information Block (L-MIB) and a Low-end System Information Block (L-SIB), which are transmitted by the transceiver to first type and second type terminals. The L-MIB includes control information on an L-subframe configuration for supporting a second type terminal and a sub-band configuration of the L-subframe, while the L-SIB includes information on downlink reception and uplink transmission of the second type terminal. When the base station receives a Random Access Channel (RACH) preamble request from one of the terminals, the base station performs the random access procedure.

    Abstract: An electronic device, a base station, and a method for managing a shared spectrum. The electronic device includes a processor configured to cause the electronic device to obtain coexistence measurement reports (CMRs) from the plurality of BSs; identify interference relationships among the plurality of BSs based on the CMRs; assign a set of BSs to one or more basic allocation units (BAUs) in a plurality of BAUs based on the interference relationships; and transmit a spectrum access grant (SAG) to the set of BSs, wherein the SAG includes BAU assignments for the set of BSs. Each BAU in the plurality of BAUs is a time/frequency unit and the set of BSs includes a primary BS and a secondary BS. The secondary BS can transmit in the one or more BAUs when a transmission of the secondary BS does not interfere with a transmission of the primary BS.

    Abstract: Methods and apparatuses for neighbor discovery and wireless inter-connection in a wireless communication system. A method for operating a base station (BS) in the wireless communication network includes generating measurement information regarding neighboring BSs of the BS in the wireless communication network; determining a first parent BS of the neighboring BSs to connect to based on the measurement information; performing an initial access procedure with the first parent BS to connect to the first parent BS; identifying an end-to-end route for the BS for transfer of data between a user equipment (UE) and a gateway via the wireless communication network; and transferring the data between the gateway and the UE based on the identified end-to-end route.

    Abstract: Methods and apparatuses for multi-path end-to-end connectivity in a wireless communication system. A BS apparatus includes a processor configured to identify congestion in the wireless communication network experienced by the BS. The processor is further configured to generate congestion feedback information indicating the congestion in the wireless communication network. The BS also includes a transceiver operably connected to the processor. The transceiver is configured to transmit the congestion feedback information to at least one other BS in the wireless communication network. The processor is configured to identify multiple of the paths that respective portions of the data are split between to be transferred between a gateway and a UE. The multiple paths are determined based at least in part on the congestion feedback information. The transceiver is configured to transfer, via the wireless communication network based on the identified multiple paths, data between the UE and the gateway.
