摘要： For a communication between two UEs that passes through a network node, a total number of transmission attempts for a same set of data is divided between first and second data transmission attempt(s). The first data transmission attempt(s) are allowed to be performed from a first one of the two UEs toward the network node. The second data transmission attempt(s) are allowed to be performed from the network node or from a second network node toward a second one of the two UEs. Performance of the first and second data transmission attempt(s) is coordinated based on the division to cause communication of the set of data from the first UE to the second UE. A single network node may perform the first and second data transmission attempts, or a first network node performs the first data transmission attempts while a second network node performs the second data transmission attempts.

摘要： Various communication systems may benefit from appropriate synchronization signal design. For example, third generation partnership project (3GPP) long term evolution advanced (LTE-A) releases 12 and 13 (Rel 12/13) may benefit from such design for device to device (D2D) communications. In particular, synchronization signals may be designed to benefit proximity services (ProSe)/D2D discovery and communication. A method can include transmitting a cellular synchronization signal on a first resource. The method can also include transmitting a device to device synchronization signal on a second resource. The first resource can be different from the second resource. The cellular synchronization signal and the device to device synchronization signal can share a same base sequence.

摘要： There are provided measures for mobility management for device-to-device communications. Such measures exemplarily include receiving a radio handover request message indicating that a radio handover of at least one communication endpoint utilizing device-to-device communication is to be hidden from core network, and determining, based on device-to-device context information, which is information on said device-to-device communication, and/or on information on said at least one communication endpoint, whether a notification of said radio handover is to be transmitted.

摘要： There is provided a method in a network element of a radio communication network, the method comprising: grouping, by the network element, a plurality of discovery patterns into at least two groups, wherein each discovery pattern comprises one or more discovery slots on radio resources for detecting discovery signals by a network node; associating at least one of the groups with a first spatial parameter and at least one other group with a second spatial parameter; and transmitting configuration information enabling a network node to utilize a discovery pattern belonging to a group associated with a spatial parameter that corresponds to spatial information of the network node.
