Abstract: A technique includes determining a number of available resources for a category of user devices, determining a number of user devices, within the category of user devices, that are connected to a base station, determining whether the number of available resources is greater than or equal to the number of connected user devices, allocating resources to one or more user devices within the category of user devices using a scheduling-based resource allocation if the number of available resources for the category is greater than or equal to the number of connected user devices within the category of user devices, and otherwise, allocating resources to one or more user devices within the category of user devices using a contention-based resource allocation if the number of available resources for the category is less than the number of connected user devices within the category of user devices.

Abstract: A technique may include receiving, by a user device in a wireless network, an indication of a set of uplink time-frequency resources to be used for an uplink transmission from the user device to both a master cell and a slave cell, determining, by the user device, a timing advance associated with the master cell, and performing a single transmission, by the user device, of a block of data to both of the master cell and the slave cell via the set of uplink time-frequency resources using the timing advance associated with the master cell.

Abstract: 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.

Abstract: 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.

Abstract: 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.
