    Abstract: A method for user equipment (UE) service handover from the serving cell to a target cell includes information regarding a handover timer and an associated handover execution condition. For scheduled handover to be performed upon expiration of the handover timer, the associated handover execution condition comprises one or more abort conditions for aborting the scheduled handover. For two-stage triggered handover to be performed upon receipt of a subsequent triggering message, the handover timer is a handover validity timer and the associated handover execution condition comprises receipt of the handover triggering message prior to expiration of the handover validity timer.

    Abstract: A server, method, and computer-readable storage medium for coverage prediction in wireless networks. The server includes a memory storing instructions and a processor operably connected to the memory, which is configured to execute the instructions to cause the server to identify a region of interest (RoI) for the coverage prediction; determine, using a neural network, a set of values for a system performance metric for areas in the RoI, respectively; and generate the coverage prediction for the RoI which associates the areas in the RoI with a determined value in the set of values. The set of values for the system performance metric is determined based on a plurality of data samples for a set of RoIs which include at least one of building height, terrain height, foliage height, clutter data that classifies land cover, line-of-sight indication data, antenna height, and ground truth data for the system performance metric.

    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: Methods and apparatuses for resource allocation and timing handling in a wireless communication network. A method of operating a base station (BS) in the wireless communication network includes communicating with at least a first parent BS of the BS in the wireless communication network according to a slot pattern of the BS. The slot pattern indicates slots on which the BS can receive and slots on which the BS can transmit. The method further includes receiving discovery information about a neighbor BS in the wireless communication network and determining whether to add the neighbor BS as a second parent BS of the BS based on the discovery information about the neighbor BS. The method further includes determining a resource allocation to the second parent BS based on the slot pattern of the BS and communicating with the second parent BS based on the determined resource allocation.

    Abstract: Methods and apparatuses for maintaining network information. A method for operating a base station (BS) in a wireless communication network includes receiving a neighbor discovery signal block (NDSB) from a neighbor BS in the wireless communication network, generating measurement information based on the NDSB, and generating a path metric for the neighbor BS based on the generated measurement information. The method further includes determining whether the neighbor BS as an interferer neighbor BS based on comparison of the path metric to a threshold and updating network information maintained at the BS based on the determination of whether the neighbor BS is the interferer neighbor BS.

    Abstract: The present invention relates to a method for transmitting, by a terminal, a sounding reference signal (SRS) or a physical uplink shared channel (PUSCH) in a mobile communication system. A communication method for a terminal in a communication system which supports the combination of configuration carrier using FDD scheme and configuration carrier using TDD scheme, in accordance with an embodiment of the present invention, comprises the steps of: receiving SRS transmission setting information from a base station; receiving uplink data scheduling information from the base station; determining whether or not the simultaneous transmission of the SRS transmission and the uplink data occurs; and setting the transmission of the uplink data or the SRS so that when the simultaneous transmission of the SRS transmission and the uplink data occurs, the sum of the respective transmission powers of the first and second symbols in an FDD cell and the first and second symbols of a TDD cell is not greater than the maximum transmission power of the terminal, wherein the timing of the first symbol in the FDD cell corresponds to the timing of the first symbol in the TDD cell, and the timing of the second symbol in the FDD cell corresponds to the timing of the second symbol in the TDD cell. In accordance with an embodiment of the present invention, defining the SRS transmission method of the terminal in a wireless communication system causes the terminal to effectively transmit the uplink data.

    Abstract: A method and a network entity in a wireless communication system sharing spectrum resources. The method includes identifying a coordination phase to identify at least one neighboring network entity using the shared spectrum resources and perform reservation of the shared spectrum resources and transmitting, during the coordination phase, a coordination request message to the at least one neighboring network entity. The method further includes receiving, during the coordination phase, a coordination response message from the at least one neighboring network entity and determining an amount of the shared spectrum resources to reserve based on the coordination response message. The method further includes transmitting, to at least one terminal in a cell of the network entity, a data transmission using at least some of the determined amount of the reserved resources.
