Embodiments use the principles of self-organizing networks to allocate resources to allow spectrum owners to share spectrum with wireless carriers according to defined license conditions. A spectrum licensee holds the licensing conditions of the spectrum licensed by the spectrum owners. This licensed spectrum is referred to as secondary spectrum. A self-organizing network server requests access to secondary spectrum. The spectrum licensee grants access to the secondary spectrum along with the licensing conditions for access. The self-organizing network server monitors the conditions associated with the license and/or delegates the responsibility for monitoring conditions associated with the license to others. When the license conditions are met, enhanced Node B systems may begin using the secondary spectrum according to the license conditions. When the license conditions are no longer met, enhanced Node B systems discontinue use of the secondary spectrum.

A test system is provided. Said test system comprises a device under test, a measurement equipment, and a remote source simulator. In this context, the remote source simulator is adapted to simulate a remote video source, wherein the remote video source is adapted to transmit a video comprising at least one detection pattern to the device under test. Furthermore, the device under test is adapted to display the video. In addition to this, the measurement equipment is adapted to detect the at least one detection pattern with respect to the device under test and to determine the number of detection patterns having been received by the device under test.

Apparatuses, methods, and systems are disclosed for switching a communication mode of a remote UE. One apparatus includes a processor (405) and a radio transceiver (425) that communicates with a relay unit (120). Here, the processor (405) decides to handover the relay unit (120) and determines a group of one or more remote units (105) associated with the relay unit (120), wherein the relay unit (120) is a relay for the group. The processor (405) selects a target base unit (110) of a mobile communication network based on the relay unit (120) and the group of one or more remote units (105) and determines a first subgroup of remote units (105) from among the group of one or more remote units (105) that cannot be supported by the target base unit (110). The processor (405) also sends, to a remote unit (105) in the first subgroup of remote units (105), a command to resume communication with the mobile communication network without using the relay unit (120).

A method performed by a connectivity-related network entity is provided. The method includes: receiving, from a Packet Data Network (PDN) gateway and a Serving Gateway (SGW), a Short Message Service (SMS) message to be sent in a downlink; determining to use a control plane only, out of the control plane and a user plane, for transferring the SMS message; transmitting a trigger message to a user equipment to initiate establishment of connectivity with the user equipment via the control plane only and not via the user plane, wherein the user equipment starts a timer when the establishment of the control plane connectivity is initiated; receiving a response message from the user equipment; encapsulating the SMS message in a security protected Non-Access Stratum (NAS) message; and transmitting the security protected NAS message to the user equipment, in receipt of which the user equipment stops the timer.

Logic may signal capability and interference control between a base station and a user equipment in an aerial vehicle. Logic may receive capabilities information from a user device to indicate that the user device is part of an aerial vehicle (AV-UE). Logic may transmit a measurement configuration to establish a trigger event based on a height or other measurement to instruct the AV-UE to transmit, in response to detection of the trigger event, a measurement report to the base station comprising interference information for downlink communications. And logic may transmit capabilities information from a user device to indicate that the user device is part of an aerial vehicle (AV-UE) and receive a measurement configuration to establish a trigger event based on a height or other measurement to instruct the AV-UE to transmit, in response to detection of the trigger event, a measurement report to the base station.

A user equipment is configured for use in a wireless communication system. The user equipment in this regard is configured to detect an orientation of an equipment coordinate frame defined for the user equipment relative to an earth coordinate frame defined for Earth. The user equipment is also configured to determine, based on the detected orientation, a set) of beams defined in the equipment coordinate frame which does not include any beam pointing in one or more predefined directions in the earth coordinate frame. The user equipment is further configured to perform a beam sweep or scan on the determined set of beams.

A terminal and a method for configuring such a terminal are provided for a user subscribed to an operator of a communication network, referred to as the nominal network, in order to access a communication service. The terminal is configured to access a first communication service via a first network access point. When the terminal is connected to a communication network other than the nominal network, referred to as a visited network, the terminal obtains data indicating whether the terminal can access a second communication service via said first network access point. In the case where the terminal cannot access the second communication service via the first network access point, the terminal determines a second network access point to be used by the terminal in order to access the second communication service and configures itself to be able to access the second communication service via the second network access point.

Disclosed are: a communication method for incorporating an IoT technique with a 5G communication system for supporting a higher data transmission rate than that of a 4G system or a subsequent system; and a system therefor. The present invention can be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security, safety, and the like) on the basis of a 5G communication technique and IoT-related techniques. A method for transmitting and receiving a signal by a base station in a mobile communication system comprises the steps of: receiving a handover request message including a first information related to a device-to-device (D2D) service for a handover target terminal; and allocating D2D resources to the terminal based on the handover request message. A communication method and device of the base station and network equipment in the mobile communication system, according to the present invention, can quickly provide, to the base station to which the terminal moves, a D2D service authorized indication of the terminal for a PLMN provided from the base station of a region to which the terminal moves, even though the terminal moves to the region at which the different PLMNs are provided, and can allow the terminal to endlessly use the services, since the terminal is allocated with the resources for the D2D services during the movement thereof.
