An obstacle recognition method and apparatus, and a related device are provided. The method includes: obtaining an actual path loss value between a first AP and a second AP, path loss value pairs between a terminal and a plurality of AP pairs, and path loss values of the plurality of AP pairs; obtaining, based on the path loss value pairs between the terminal and the plurality of AP pairs, an AP pair similar to an AP pair formed by the first AP and the second AP; obtaining a second path loss value between the first AP and the second AP based on a path loss value of the similar AP pair; and comparing the second path loss value between the first AP and the second AP with the actual path loss value, to determine whether an obstacle exists between the first AP and the second AP.

The present invention relates to a method and an apparatus for a base station transmitting a downlink signal for a machine-type communication (MTC) terminal. More specifically, the present invention relates to a method for transmitting and receiving PBCH, PRACH, PDSCH, PDCCH or EPDCCH for a low cost and enhanced coverage MTC terminal, and an apparatus therefor. Particularly, provided are an apparatus and a method for a base station transmitting a control channel, the method comprising the steps of repeatedly transmitting a control channel comprising control information, and repeatedly transmitting downlink data channel (PDSCH) on the basis of information for a subframe ending the control channel being repeatedly transmitted.

Embodiments of an apparatus and method are disclosed. In an embodiment, a method of multi-link communications involves at a first multi-link device, generating a management frame having reduced neighbor report (RNR) information related to the first multi-link device, and at the first multi-link device, transmitting the management frame having one of the RNR information and a multi-link element (ML IE) or both the RNR information and the ML IE to a second multi-link device.

A method of initiating handover of a wireless device includes determining one or more of a low battery condition, a low power headroom, and a high buffer status of a wireless device. The wireless device can be attached to a first access node deploying multiple radio access technologies over a first coverage area. The method further includes identifying a second access node deploying a single radio access technology over a second coverage area encompassing a location of the wireless device, and initiating handover of the wireless device from the first access node to the second access node based at least in part on the one or more of the low battery condition, low power headroom, and high buffer status of the wireless device. Systems and devices relate to initiating handover of a wireless device.

A system described herein may provide for the use of modeling techniques to generate models associated with various locations or regions (e.g., sectors) associated with one or more radio access networks (“RANs”) of a wireless network, as well as for one or more mobile radio units (“MRUs”) that include wireless network infrastructure and which may be dynamically moved from one location to another. The system may identify attributes of a location within the network at which the MRU is located, and may automatically configure base stations of the RAN as well as the wireless network infrastructure of the MRU in order to optimize the operation of the RAN, as well as to gain optimal usage of the MRU.

A dual band LTE small cell base station communicates on both licensed bands and unlicensed bands. The small cell base station modifies the communication protocol utilized by the licensed band to enable communication over an unlicensed band. This modification involves replacing the physical (PHY) layer of the licensed band communication protocol with the PHY layer of a to-be-used protocol in an unlicensed band.
