Abstract: First and second level discovery messages for device-to-device discovery are determined to be going to be transmitted, resource(s) are requested for transmission of at least the second level discovery message, and allocated resource(s) of a second type are received. The first level discovery message is transmitted on either a selected resource of the first type or a selected one of the allocated resource(s). The second level discovery message is transmitted on a selected one of the more allocated resource(s) of the second type, A first level discovery message is received on a resource of either a first type or a second type. It is determined whether the received message is of interest or not and if the message is of interest, then it is determined whether a second level discovery message is available and if so, the second level discovery message is received on a resource of the second type.

Abstract: Embodiments of the disclosure provide methods and apparatuses for managing a COMP set in a communication system employing an ASA scheme. According to the method, change information about an affected cell is received, wherein the change information uses an ASA frequency band and overlaps with a protected area of a primary system authorized with the ASA frequency band. The change information is then sent to a serving node coordinating transmission within constituent cells of a CoMP set, to indicate a change of the CoMP set, wherein the affected cell is one of the constituent cells of the CoMP set.

Abstract: Systems, methods, apparatuses, and computer program products for D2D synchronization in, for example, partial coverage scenarios are provided. One method includes sending, by a network node, information to at least one user equipment in a network. The information may be used by the at least one user equipment to determine whether the at least one user equipment is a full-coverage idle mode user equipment or a downlink-only idle mode user equipment. When, for instance at least one of a pair of device-to-device (D2D) user equipment is outside of the network coverage area, the method includes indicating via a cellular broadcasting message to the downlink-only idle mode and the full-coverage idle mode user equipment to send at least one synchronization signal. The method may then include configuring a RRC_Connected mode user equipment at cell-edge to monitor whether there are user equipment sending synchronization signals.

Abstract: Various communication systems may benefit from techniques and systems for resource allocation. For example, communication systems of the third generation partnership project may benefit from device to device discovery resource allocation methods and systems. A method can include determining that downlink data transmission may cause conflict between uplink control channel transmission and device to device discovery signal transmissions or that uplink shared channel transmissions may conflict with device to device discovery signal transmissions; and requesting a user equipment to report device to device discovery needs based on the determining.

Abstract: Systems and techniques for synchronization between in-coverage and out-of coverage user devices. A base station configures in-coverage and out-of coverage synchronization signals and configures user devices to recognize synchronization signals as in-coverage or out-of-coverage. An in-coverage device furnishes an in-coverage synchronization signal upon detection of an out-of coverage signal, and may continue to furnish the signal upon continued detection of an out-of-coverage signal that is not synchronized to the network. An out-of-coverage device may receive and synchronize to an in-coverage signal if available, or an out-of-coverage signal if available, or may generate and transmit its own out-of-coverage signal if no in-coverage or out-of-coverage signal is available. Signals may include rank information to indicate relay sequence information, and user devices may be configured to respond to signals based on the rank information—such as favoring a signal whose rank indicates that the signal represents a lower relay order number.
