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: Various communication systems may benefit from inter-operator device-to-device operation. For example, communication systems of the third generation partnership project (3GPP) long term evolution (LTE) advanced (LTE-A) release12/13 (Rel-12/13) or future releases may use such operation with respect to D2D communications. A method can include preparing, at a network element operated by an operator, radio resource information related to one or more operators other than the operator. The method can also include broadcasting, by the network element, the radio resource information. The radio resource information can be configured to permit a user equipment served by the network element to perform device-to-device discovery and/or communication with another user equipment served by at least one of the one or more operators.

Abstract: Configuration of various radio systems may have a number of possible benefits. For example, small cell configuration may be useful for interference mitigation. A method, in certain embodiments, can include determining a virtual subframe index for a cell. The method can also include communicating the virtual subframe index for the cell by communicating a time division duplex configuration and a relative subframe offset.

Abstract: Various embodiments of the present invention provide a method for cell reselection, comprising: receiving, at a user equipment, system information from a network node that is shared by two or more operator networks, wherein the system information comprises first information associated with at least one operator network related to one or more neighboring cells for the user equipment; determining whether there is an operator network accessible to the user equipment in the at least one operator network, based at least in part on the first information; and performing a cell reselection procedure only when one or more accessible operator networks are determined.

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.
